How to improve the quality of precision mold parts?

1, the design of the parts should be reasonable
Choose the best structural plan as much as possible, and the designer of the part must consider the technical requirements of the part and its structure must meet the manufacturability and feasibility of mold manufacturing.
2, mold design is the most important step to improve mold quality
①. In addition to meeting customers' requirements for product quality, we also need to consider the cost of the material and its strength within the set period of the selected mold material. Of course, it must also be based on the type of mold, use of work methods, and processing. Factors such as speed and main failure modes are used to select materials.
②. When designing the mold structure, try to be as compact as possible, easy to operate, and ensure that the mold parts have sufficient strength and rigidity; when the mold structure allows, the corners of the mold parts should be designed as rounded transitions as much as possible to avoid stress concentrated;
③. In the design, the scope of disassembly and assembly must be reduced when repairing a certain part, especially when the wearing parts are replaced, the scope of disassembly and assembly should be reduced as much as possible.
3, the mold manufacturing process is also an important part of ensuring the quality of the mold
The processing method and processing accuracy in the manufacturing process of precision mold parts will affect the service life of the mold. The accuracy of each part directly affects the overall assembly of the mold. In addition to the accuracy of the equipment itself, it is necessary to improve the processing method of the parts and improve the technical level of the fitter in the mold grinding and matching process to improve the processing accuracy of the mold parts ;
4, Surface strengthening of the main forming parts of the mold
Improve the surface wear resistance of precision mold parts, so as to better improve the quality of the mold. For surface strengthening, different strengthening methods should be selected according to different use molds.
5, the correct use and maintenance of the mold is a major factor in improving the quality of the mold
The mold installation and debugging method should be appropriate. In the case of hot runners, the power supply wiring must be correct, the cooling water circuit must meet the design requirements, and the parameters of the injection molding machine, die casting machine, and press in the mold production must meet the design requirements, etc. .
