⑶The mold manufacturing process is also an important part of ensuring the quality of the mold. The processing method and processing accuracy in the mold manufacturing process will also 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 methods of the parts and improve the technical level of the fitter in the mold grinding process to improve the processing accuracy of the mold parts ; If the overall assembly effect of the mold does not meet the requirements, the probability of the mold moving in an abnormal state in the trial mold will increase, which will have a great impact on the overall quality of the mold. Luo Baihui, an expert in the mold industry, pointed out that in order to ensure that the mold has a good original precision-the quality of the original mold, in the manufacturing process, a reasonable high-precision processing method must be selected first, such as EDM, wire cutting, CNC machining, etc., while paying attention to the mold The accuracy inspection of the mold includes the processing accuracy of the mold parts, the assembly accuracy and the comprehensive inspection of the accuracy of the mold through the test and acceptance work. In the inspection, it is necessary to use high-precision measuring instruments as much as possible. For those mold parts with complex surface and curved structures, if Accurate measurement data cannot be achieved with ordinary rulers and vernier cards. At this time, precise measurement equipment such as a coordinate measuring instrument must be selected to ensure the accuracy of the measurement data.

(4) Surface strengthening of the main forming parts of the mold to improve the wear resistance of the surface of the mold parts, so as to better improve the quality of the mold. For surface strengthening, different strengthening methods should be selected according to different uses of molds. For example: the blanking die can be strengthened by electric spark, cemented carbide surfacing, etc., to improve the wear resistance and compressive strength of the surface layer of the mold parts; die-casting molds, plastic molds and other hot-processed mold steel parts can be nitrided (hard nitrogen Chemical) treatment to improve the wear resistance, heat fatigue resistance and corrosion resistance of the parts; drawing dies and bending dies can be treated with sulphurization to reduce the friction coefficient and improve the wear resistance of the material; carbonitriding (Soft nitriding) can be applied to the surface strengthening treatment of various molds. In addition, a technology called FCVA vacuum diamond coating developed in recent years can form a protective film on the surface of the part that is extremely strong and very smooth and uniform with the substrate. This technology is particularly suitable for mold surface protection. Treatment is also an effective way to improve the quality of molds. Of course, if the part is a trial product or the production batch is quite small, the surface strengthening treatment of the mold part is not necessary.

⑸ The correct use and maintenance of molds is also a major factor in improving mold quality. For example, the installation and debugging method of the mold 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. and many more. When using the mold correctly, it is also necessary to perform regular maintenance on the mold. The guide posts, guide sleeves and other parts of the mold should be filled with lubricating oil frequently. For forging molds, plastic molds, die-casting molds, etc. Lubricant or mold release agent should be sprayed on the surface of the molded part before molding. The planned protective maintenance of the mold and the data processing in the maintenance process can prevent possible problems in the mold production and improve the maintenance efficiency. Luo Baihui believes that if we want to improve the quality of molds, we must first consider the impact on mold quality in every link, and secondly, we must cooperate with all departments. The quality of the mould is the true embodiment of the mould enterprise's own strength.

Quality is the life of a brand, and the quality of molds will directly affect the quality, output, cost, cycle of new product production and old product replacement, the speed of corporate product structure adjustment and market competitiveness, so the economic situation Quality puts forward higher and higher requirements. Whether it is the designer and manufacturer of the mold, the designer of the part, or the user of the mold, it is a problem that should be actively concerned.
