Characteristics of precision mold parts processing machine tools
Precision mold parts processing is one of the most effective methods of mold processing. Compared with traditional processing techniques, precision mold parts processing machine tools adopt a procedure that reduces the number of workpiece installations and operating steps, while maintaining directional positioning and perfect manufacturing process. However, in order to ensure the precision of mold parts processing, improve the quality of production and reduce production costs, precision mold parts processing machine tools have strong oxidizing properties and also exhibit the following characteristics:
(1) It has a certain lower deformation resistance and a certain temperature range.
(2) The cutting volume is relatively large, the wear degree is relatively low, and the surface roughness is low
(3) The high and balanced surface strength of quenching.
(4) The quality requirements for the grinding wheel and the cooling environment are unstable, and precision mold processing machine tools are not prone to damage and cracks.
What are the material requirements for precision mold parts?
Under the current technical conditions, the cost of hardened film deposition technology (mainly equipment) is relatively high, and it is still only used on some precision, long-life mold parts. If a heat treatment center is established, the cost of applying hardened film will be greatly increased. If more mold parts adopt this technology, my country's mold parts manufacturing level can be improved as a whole.
In addition to the high enough strength and toughness required for mold parts during operation, their surface properties are crucial to the working performance and service life of mold parts. To improve these properties, relying solely on the improvement and improvement of the base material is very limited and uneconomical. However, through surface treatment technology, you can often get twice the result with half the effort. This is why surface treatment technology has developed rapidly. These surface properties refer to: wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc.
The purpose of carburizing mold parts is mainly to improve the overall strength and toughness of mold parts, that is, the working surface of mold parts has high strength and wear resistance. The technical idea introduced is to use lower-grade materials, that is, through Carburizing and quenching are used to replace higher grade materials, thereby reducing manufacturing costs. Hardened film deposition technology was first applied to tools (knives, cutting tools, measuring tools, etc.) with excellent results. Many cutting tools have adopted hardened film coating as a standard process. The currently more mature hardened film deposition technologies are CVD and PVD. In order to increase the bonding strength of the film workpiece surface, a variety of enhanced CVD and PVD technologies have been developed. Mold parts have been coated with hardened film technology since the 1980s.
Spark wire cutting processing of precision mold parts
The basic principle of wire EDM processing of mold parts is. The mold accessories are connected to the positive pole of the pulse power supply, and the electrode wire is connected to the negative pole. After adding a high-frequency pulse power supply between the mold accessories and the electrode wire, a strong pulse electric field will be generated between the mold accessories and the electrode wire, causing the working fluid medium between them to Pulse discharge occurs due to ionization breakdown, and the discharge of electric spark is used to ablate mold parts materials. During the ablation process, under the interpolation control of the machine tool CNC system, the stepper motor causes the workbench to move the mold parts relative to the electrode wire according to the required processing shape orbit. As the electrode wire passes, electric sparks By continuously ablating the metal material between the mold parts and the electrode wire, the required shape of the mold parts can be gradually cut out.
Like all EDM machining methods, there are also issues with polarity effects in wire EDM machining. In order to obtain better surface machining quality and higher dimensional accuracy, the corrosion of the electrode wire needs to be minimized as much as possible during the machining process. Therefore, the electrode wire is connected to the negative electrode of the pulse power supply and the mold fitting is connected to the positive electrode, so that the electrode wire suffers minimal corrosion. In order to reduce processing errors caused by the ablation of the electrode wire, the electrode wire needs to be continuously moved axially to prevent excessive ablation of the electrode wire at a certain position. In addition, during the processing, a large amount of liquid medium needs to be continuously injected into the discharge gap to ensure that the electrode wire is fully cooled and flushed, and to ensure that normal spark discharge can be continuously formed between the electrode wire and the mold parts. , to prevent arc discharge.
What are the essential characteristics of precision mold parts?
01.Wear resistance
When the precision mold parts blank is plastically deformed in the mold cavity, it both flows and slides along the cavity surface, causing severe friction between the cavity surface and the blank, causing the mold to fail due to wear. Therefore, the wear resistance of materials is one of the most basic and important properties of molds.
Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear amount and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
02.Strong toughness
Most of the working conditions of molds are very harsh, and some often bear large impact loads, resulting in brittle fracture. In order to prevent mold parts from suddenly breaking during operation, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organizational state of the material.
03. Fatigue fracture performance
During the working process of the mold, fatigue fracture is often caused under the long-term action of cyclic stress. Its forms include small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
04.High temperature performance
Precision mold parts When the working temperature of the mold is high, the hardness and strength will decrease, leading to early wear or plastic deformation of the mold and failure. Therefore, the mold material should have high
anti-tempering stability to ensure that the mold has high hardness and strength at the working temperature.
05. Heat and cold fatigue resistance
Some molds are in a state of repeated heating and cooling during the working process, which causes the surface of the cavity to be subjected to tension and pressure changes, causing surface cracks and peeling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy, resulting in Mold failure. Hot and cold fatigue is one of the main forms of failure of hot work molds. This type of mold should have high cold and hot fatigue resistance.
6. Corrosion resistance
When some molds, such as plastic molds, are working, due to the presence of chlorine, fluorine and other elements in the plastic, highly corrosive gases such as HCI and HF are decomposed after being heated, which erodes the surface of the mold cavity, increases its surface roughness, and aggravates wear and failure.
