The quality of plastic mold includes the following aspects:
⑴Product quality: product scale stability, fit, product surface finish, product data utilization rate, etc .;
⑵ Service life: on the premise of ensuring product quality, the number of working cycles that the mold can complete or the number of manufactured parts;
⑶The use and maintenance of the mold: whether it is the most convenient to use, the demolding is simple, and the production assistance time is as short as possible;
⑷ Repair cost, repair periodicity, etc.

The fundamental way to improve the quality of the mold: the planning of the mold is the most important step to advance the quality of the mold. Many factors need to be considered, including the selection of mold information, the usability and safety of the mold structure, the processability of the mold parts and the The convenience of mold repair, these should be considered as much as possible at the beginning of planning. The manufacturing process of the mold is also an important part of ensuring the quality of the mold. The processing methods 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 installation of the mold. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the processing method of the parts and advance the skill level of the fitter in the mold grinding process to advance the processing accuracy of the mold parts. Surface strengthening of the first forming parts of the mold to advance the surface wear resistance of the mold parts, and then better advance the quality of the mold. The correct use and maintenance of the mold is also a major factor in advancing the quality of the mold.
For example, the equipment debugging mode of the mold should be appropriate. In the case of a hot runner, the power supply wiring must be correct, the cooling water channel must meet the planning requirements, and the parameters of the injection molding machine, die casting machine, and press during the production of the mold must match the planning requirements. and many more. When using the mold correctly, it is necessary to maintain the mold on time. The guide pillars, guide sleeves and other parts of the mold that have relative motion should be filled with lubricating oil. The molds such as forging molds, plastic molds, and die casting molds are Before forming each mold, lubricant or mold release agent should be sprayed on the surface of the formed parts.
With the development of society, the quality of molds has been paid more and more attention. With the strengthening of planning and manufacturing molds, and the realization of new mold skills, mold quality has been paid more and more attention. Quality is a topic that is often said and new, and quality is advancing with the improvement of mold skills.
