Correct maintenance method of plastic mold parts

Regular maintenance of plastic mold parts plays a vital role in the service life of the mold. The annual maintenance procedures required for each injection molding location depend on the different mold cycles. The following are some plastic mold parts maintenance tips that each mold user can use to ensure the effective operation of mold components such as hot runners, heaters, guide posts and ejector pins, and molding inserts to prevent unexpected situations.

1. Check whether there is early warning signs of rust or moisture at the air vents. If you find rust or moisture near the hot runner exhaust hole, it means internal condensation or the water pipe may be broken. Moisture can cause a fatal short circuit to the heater. If the machine is not running year-round and needs to be shut down at night or on weekends, the chances of this condensation occurring will increase.

2. Remember to remind the operator not to "clean" the hot nozzle at the gate. If the operator happens to see a small piece of stainless steel at the nozzle of the mold fitting, it may be a nozzle assembly. "Clearing" this seeming obstruction often ruins a hot mouthpiece. In order not to damage the hot nozzle, please confirm the nozzle type of the hot runner system before taking action, and ensure that all operators are well-trained and can identify the different types of nozzles they come into contact with.

3. Sliding stop buckle. For machines that run year-round, this job should be done once a week. The end of the year is a good time to perform routine lubrication and maintenance on these parts.

4. Interactively verify the resistance value of the heater. You should have measured the resistance of the heater when you first started using it, and again at the end of the year to compare. If the resistance value fluctuates by ±10%, you should consider replacing the heater to ensure that it does not fail at a critical moment in the production process. If the initial resistance value has never been measured, measure it once and use the resulting value as reference data for future inspections of the heater.

5. Check whether there are signs of wear between the guide post and the guide sleeve. Look for signs of scratches or abrasions. This kind of wear on plastic mold parts is caused by lack of lubrication. If the marks are new, you can also extend the life of the guide posts and bushings by lubricating them. If the wear is severe, it should be replaced with new parts. Otherwise, the cavity and core parts may not fit well, resulting in parts with different cavity wall thicknesses.

What role do stamping die parts play in high-end processing?

1. Provide more services and form an industrial chain

At present, domestic private mold companies generally have advanced equipment resources. The technical application of stamping die parts is relatively advanced. New technologies can be widely and rapidly adopted in industries. From design and manufacturing to related material production and heat treatment, an industrial chain is formed 

2. Reduce resource consumption and waste emissions

It is necessary to promote the pilot project of circular precision economy in my country's stamping die parts industry, focusing on reduction, reuse and resource conversion to reduce resource consumption and waste emissions, and actively implement preferential policies for comprehensive utilization of national resources. 

3. Easily process fine areas

The basic requirements for stamping die parts processing are to obtain high precision, smooth part surface quality, and easy-to-machine fine areas. Stamping die parts can be adjusted to larger tolerances during semi-finishing, saving calculation time. Choose tools better than those used for finishing, or remove roots beforehand to avoid tool collisions at corners during finishing

All in all, stamping die parts have found that during actual machining, especially finishing, the PTP file output is larger when using fixed axis milling. Another arc interpolation method provided by high-quality stamping die parts, which greatly reduces post-processing matters, reduces the machine's pre-read load, and can easily achieve high feed speeds. Maintains very high finish and surface quality

How to choose the right materials for mold parts is the key to smooth mold production

1. Good mechanical processing performance. Choose a steel grade that is easy to cut and can produce high-precision parts after processing.

2. Excellent polishing performance. The working surface of injection molded parts often needs to be polished to a mirror surface, Ra≤0.05μm. The hardness of the steel is required to be HRC35~40. A surface that is too hard can make polishing difficult. The microstructure of the steel should be uniform and dense, with very few impurities and no defects or pinpoints.

3. Good wear resistance and fatigue resistance. The injection mold cavity is not only washed by high-pressure plastic melt, but also affected by alternating hot and cold temperature stresses. General high-carbon alloy steel can obtain high hardness through heat treatment, but it has poor toughness and is prone to surface cracks, so it should not be used. The selected steel type should enable the injection mold to reduce the number of polishing and repairs, maintain the dimensional accuracy of the cavity for a long time, and achieve the service life of the planned mass production.

4. Corrosion resistant. For some types of plastics, such as polyvinyl chloride and flame-retardant plastics, steel types with corrosion resistance must be considered.

Main factors affecting precision mold injection molding

The basis for judging precision injection molding is the accuracy of the injection molded product, that is, the dimensional tolerance, geometric tolerance and surface roughness of the product. There must be many related conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molds, injection molding processes and injection molding equipment. When designing plastic products, engineering plastic materials should be selected first, and engineering plastics that can be used for precision injection molding must use materials with high mechanical properties, dimensional stability, good creep resistance, and resistance to environmental stress cracking. Secondly, an appropriate injection molding machine should be selected based on the selected plastic material, finished product dimensional accuracy, piece weight, quality requirements and expected mold structure. During the processing process, the factors that affect precision injection molded products mainly come from the accuracy of the mold, injection shrinkage, and the change range of the environmental temperature and humidity of the product. 

In precision injection molding, molds are one of the keys to obtaining precision plastic products that meet quality requirements. The molds used for precision injection molding should actually meet the requirements of product size, accuracy and shape. However, even if the accuracy and size of the mold are consistent, the actual size of the molded plastic products will be inconsistent due to differences in shrinkage. Therefore, effectively controlling the shrinkage rate of plastic products is very important in precision injection molding technology.

Whether the mold design is reasonable or not will directly affect the shrinkage rate of plastic products. Since the mold cavity size is calculated by adding the size of the plastic product to the estimated shrinkage rate, the shrinkage rate is recommended by the plastic manufacturer or the engineering plastics manual. A value within a range, which is not only related to the gate form, gate position and distribution of the mold, but also to the crystallization orientation of the engineering plastic.

It is related to the shape, size, distance to the gate and location of the plastic product. The main factors that affect the shrinkage of plastics include thermal shrinkage, phase change shrinkage, orientation shrinkage, compression shrinkage and elastic recovery, and these influencing factors are related to the molding conditions or operating conditions of precision injection molded products. Therefore, the relationship between these influencing factors and injection molding conditions and their apparent factors must be considered when designing the mold, such as injection pressure, cavity pressure and mold filling speed, injection melt temperature and mold temperature, mold structure and gate form and distribution. , as well as the influence of factors such as gate cross-sectional area, product wall thickness, reinforcing filler content in plastic materials, crystallinity and orientation of plastic materials. The influence of the above factors also varies due to different plastic materials, other molding conditions such as temperature, humidity, continued crystallization, internal stress after molding, and changes in the injection molding machine.

Because the injection molding process is a process of transforming plastic from solid powder or granules to liquid melt and then to solid products. From pellets to melt, and then from melt to finished products, the process must go through the effects of temperature field, stress field, flow field, density field, etc. Under the combined action of these fields, different plastics are thermosetting or thermoplastic, crystalline or Amorphous, reinforced or non-reinforced polymers have different structural morphologies and rheological properties. Any factors that affect the above fields will inevitably affect the physical and mechanical properties, size, shape, accuracy and appearance quality of plastic products. In this way, the intrinsic relationship between process factors and polymer properties, structural morphology and plastic products will be expressed through plastic products. Analyzing these intrinsic relationships clearly is of great significance to rationally formulating injection molding processing technology, rationally designing and manufacturing molds according to drawings, and even rationally selecting injection molding processing equipment. There are also differences in injection pressure and injection rate between precision injection molding and ordinary injection molding. Precision injection molding often uses high-pressure or ultra-high-pressure injection and high-speed injection to obtain smaller molding shrinkage. Based on the above reasons, in addition to considering the design elements of general molds when designing precision injection molds, the following points must also be considered:

①Adopt appropriate mold size tolerances;.

②Prevent molding shrinkage errors;

③Prevent injection molding deformation;

④Prevent demoulding deformation;

⑤ Minimize mold manufacturing errors;

⑥Prevent mold accuracy errors;

⑦Maintain mold accuracy.
