How to improve the quality of plastic molds? The quality of the mold includes the following aspects:

⑴Product quality: product size stability, compliance, product surface finish, product material utilization rate, etc .;

⑵Using life: under the premise of ensuring the quality of the product, the number of operating cycles that the mold can complete or the number of parts produced;

(3) mold application protection: whether it is convenient to use, easy to demold, and the production support time is as short as possible;

⑷ Repair cost, repair period and so on.

The fundamental way to improve mold quality: mold design is an important step to improve mold quality. Many factors need to be considered, including the selection of mold materials, the usability and safety of mold structure, the processability of mold parts, and mold repair. Convenience, these should be considered as comprehensively as possible at the beginning of the design. The manufacturing process of the mold is also an important part to ensure 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 component directly affects the overall condition of the mold. In addition to the impact of the accuracy of the equipment itself, it is necessary to improve the processing method of the part and the skill level of the fitter in the mold grinding and matching process to improve the processing accuracy of the mold part. The appearance of the primary forming parts of the mold is strengthened to improve the wear resistance of the mold parts, thereby improving the quality of the mold. The correct use and protection of the mold is also a major factor in improving the quality of the mold.

For example, the mold device 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 machine must meet the design requirements during the production of the mold. and many more. When the mold is used correctly, the mold must be regularly protected and maintained. Lubricants should be frequently filled into the guide posts, guide sleeves and other parts of the mold. Lubricants such as forging dies, plastic dies, die-casting dies, etc. Lubricant or mold release agent should be sprayed on the surface of the molded parts before forming.

With the development of the society, the quality of molds has been paid more and more attention. With the enhancement of the design and production of molds, the realization of new mold skills, the quality of molds has received more and more attention. Quality is often a new topic, and quality is improving with the improvement of mold skills.
