How to open the mold to ensure the perfection of the precision mold!

1. Release of vehicle body process data

The body design department releases the product digital model, and the engineers in the engineering development department conduct process pre-analysis and pre-quotation (as bidding comparison data) based on the product digital model. They use the body process digital model to conduct bidding for precision plastic molds and corresponding process analysis. The bidding process will not be discussed in detail here, but the mold development management will be discussed briefly after the bid is determined (that is, the mold factory is determined).

2. Feasibility analysis of vehicle body parts manufacturing process (mold developer and engineering development department)

After receiving the digital model of the car body process, the precision mold developer conducts a process feasibility analysis on each part. In principle, mold factories are required to conduct CAE analysis (ie part formability simulation analysis) on all newly developed parts.

The role of CAE analysis:

Through CAE analysis, we can more intuitively observe the forming process of parts and sheets;

Shorten the mold design and analysis cycle;

Predict the possibility of precision molds;

Adopt optimized design to minimize the consumption of precision molds and steel and reduce manufacturing production costs;

Preemptively identify potential risks in molds and parts before manufacturing;

Ensure the rationality of mold design and reduce design costs;

By analyzing potential problems of precision parts, mold factories can promptly make reasonable suggestions for design changes and advance development work more efficiently. The development department can make full use of the on-site production and debugging experience based on the mold factory's CAE analysis results of the parts to check whether the process parameters are reasonable and whether the drawing supplement is reasonable, and timely propose solutions for risks such as wrinkling or cracking of parts.

3. Design and countersigning of DL diagram

After the CAE analysis is completed, the mold DL drawing design can be carried out, and in most cases it can also be done at the same time.

DL diagram design is design layout - stamping process analysis and design, which can also be called mold process flow chart. It includes: size of part piece, stamping direction and angle, stamping process arrangement, feeding direction, scrap knife distribution and cutting edge direction. , scrap removal direction indication, CH hole, left and right parts identification, labeling of each process, etc.

At the same time, the DL diagram also needs to reflect the stamping equipment of the relevant process, the height of the mold, the material of the mold, the working stroke of the blank holder or clamping plate, the positioning method of the sheet, and the pressure analysis of the completed process, etc.

After the DL design is completed, in principle, an internal audit should be completed at the mold factory. After the rectification of the internal audit issues is completed, it can be provided to the development department of the OEM and counter-signed. The counter-signing of the DL drawing is very critical and will directly lead to the later design of the mold, and It also has a great impact on the later mold development cycle. If the DL drawing is changed later, it will cause a lot of waste in the development cycle and cost. The engineering development department mainly reviews the rationality of the part process, the correctness of the machine parameters, The rationality of process supplementation, material utilization rate, and the convenience of feeding materials should be reviewed based on the conditions of the press.

4. Mold structure drawing design and countersigning

The order of countersigning on precision mold structure drawings: countersigning on drawing mold drawings - countersigning on shaping and flanging molds - countersigning on trimming and punching molds. Because the casting and processing cycle of the mold is a hard time and cannot be compressed, in order to ensure the progress of the project, the mold structure diagram design link is very important. The mold design link should be advanced as much as possible to gain time for subsequent mold manufacturing.

The first sampling of the mold is usually a semi-manual sample, which only requires shaping. The remaining trimming and punching can be completed by wire cutting. Therefore, the drawing mold and shaping and flanging molds should be designed first, and then trimming and punching are carried out. Mold drawing design.

The mold factory designs the mold structure diagram according to the guidance of the DL drawing. After the design is completed, it also passes the internal review. After the problems are rectified, it can be reviewed and countersigned by the development department of the OEM.

The OEM development department should focus on:

Mold functionality

Structural stability and strength

Mold production safety

Compliance of mold parameters with mass production press

Ease of commissioning and production

The material of the main parts of the mold and the consistency of the terms required by the technical agreement

For problems discovered during the review, the mold factory should be required to make rectifications as much as possible. Some problems may have little impact on product functions, etc., but may affect the convenience of operations and may also reduce production efficiency. In order to meet the deadline and schedule, the mold factory may not be very cooperative with the changes. At this time, the OEM developers (engineers) ) courage and determination, because changes in the design stage are faster than changes in the later stage (after the mold is formed). At this time, the designers of the mold factory need to think differently and look at the problem from the perspective of the production department. Some controversial issues require objective discussions among multiple parties to find the best solution. During the mold drawing review process, engineering development technicians are required to be firm and have strong technical and on-site debugging experience, which can reduce many problems in the later stage.

5. Casting digital model release and foam mold review and rectification

After the mold structure drawing design review is completed, the foam mold can be produced. During the foam real mold stage, the project team needs to release casting data to ensure the castability of the real mold. The foam real mold is a material formed by high-temperature foaming of polystyrene. NC processing is performed according to the mold structure diagram, and Consider appropriate mold machining allowance (8-10 days) and foam shrinkage.

The production cycle is generally about a week. After the production is completed, it needs to be reviewed on site. First, to ensure consistency with the mold structure drawing. The second is to check whether the problems that occurred in the mold structure drawing review have been rectified in place, or whether the problems were not found in the design drawing review. The review is an indispensable process in the mold production process, because it is the last step in the mold structure change. Entering the casting stage, the mold structure is difficult to change.

6. Mold casting

After the production and rectification is completed, it can be shipped to the foundry for casting. The specific process will not be discussed in detail here. The mold casting cycle is 15-20 days. The mold casting will be transported back to the mold factory for casting inspection, mainly to check whether there are any large castings. Defects, such as casting cracks, etc. Among them, defects such as sand inclusions inside the castings need to be processed before they can be seen. 

7. NC digital model release and NC processing of molds

After the precision mold casting is completed, NC processing can be carried out, but the premise is that the NC data has been released. The mold factory can perform NC programming based on the NC data of the product, and then perform NC processing of the mold. The NC processing of the mold can be roughly divided into: Long milling- Assembly - semi-finishing - finishing, etc. During the NC processing, it can be found whether the casting has defects such as sand inclusions or cracks. After the NC processing is completed, the mold needs to be heat treated to achieve the required hardness. The NC of the mold The processing cycle is generally 20-25 days. When the project development time is tight, it is very important to reasonably arrange the NC processing time. Engineering developers can go to the site to control the progress and supervise the mold factory to prepare a reasonable processing plan. Try not to let the CNC machining machine idle to ensure progress.

8. Mold fitter, debugging, and sampling process

The fitter stage of precision molds includes: mold benchmarking - mold clamping - mold trial - sampling, etc. After NC processing of the mold, there is still a certain margin for subsequent fitter work. The fitter debugging mainly checks the grinding rate of the upper and lower molds, and the grinding and grinding of the guide. efficiency to ensure that qualified stamping parts are punched out. Through mold fitter debugging, the quality of the mold can be identified, and the size of the blank can also be determined.

9. Mold pre-acceptance

After the precision mold factory completes the production of all contracted molds within the planned time and passes the self-debugging, it can apply to the development department of the main engine factory for pre-acceptance. The mold factory needs to provide the self-inspection report of the mold and the qualification rate of the stamped parts. The development department of the main engine factory After receiving the pre-acceptance application from the mold factory, organize personnel to go to the mold factory for pre-acceptance. The mold is mainly inspected from three aspects: static and dynamic stamping parts quality of the mold. The dynamic and static inspections are performed in accordance with the standards. The stamping parts inspection is divided into surface inspection and Three aspects: quality, shape and size accuracy and stiffness.

In principle, problems found during the pre-acceptance process must be packaged and shipped after the mold factory has completed rectification. However, if some problems do not affect the production quality and are difficult to rectify, they are allowed to be left to the mass production site by the mold factory under tight schedules. Self-dispatched fitter personnel continue to make rectifications.

10. Debugging and acceptance of mold mass production site

Due to differences in machine tools, mold surface grinding rates, etc., it is necessary to ensure the quality of the parts. After the mold is pre-accepted, it needs to be debugged after it is moved to the mass production site. Generally, the first round of grinding and mixing time for drawing molds is 1-2 months, and the entire mold debugging cycle lasts for half a year or more. The debugging process of the mold mass production site always focuses on the following aspects:

The stamping parts need to be clamped on the welding fixture to verify the coordination of the mold, clamp, inspection tool, inspection tool and welding fixture;

To ensure the accuracy of stamping parts, place the stamping parts on the inspection tool for inspection. The required pass rate is generally above 90%;

Problems found on stamping parts on inspection tools or problems or defects reported during welding and debugging must be rectified by the mold factory; Compliance inspection of mold dynamic and static inspection items;

The reliability of continuous production of molds on mass production presses, that is, the continuous production scrap rate is required to be less than 2%

The mold debugging and rectification cycle is long. After the above rectifications are completed and production runs stably for 3 months, the engineering development department can organize the mold user, security personnel, quality inspection personnel, etc. to conduct the final acceptance of the mold and sign the final acceptance report. 

After the final acceptance of the precision mold, the mold development work is completed in stages. However, as long as the mold is not scrapped and the mold life cycle continues, the work of the engineering development department will never end, but will be handed over to the production system and process department for use, management, maintenance, etc. With good use and maintenance, molds can extend their service life, reduce scrap rates, improve production efficiency, and bring considerable economic benefits to the company.
