How to improve the quality of mould

The mold quality introduced by the mold manufacturer includes the following aspects:

⑴ Product quality: stability and conformity of product dimensions, surface finish of products, utilization rate of product materials, etc;

(2) Service life: on the premise of ensuring product quality, the number of working cycles that the mold can complete or the number of parts produced;

(3) Use and maintenance of the mold: whether it is convenient to use, easy to demould, and the auxiliary production time should be as short as possible;

(4) Maintenance cost, maintenance cycle, etc.

The basic way to improve mold quality: mold design is an important step to improve mold quality, and 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 the convenience of mold maintenance. These should be considered as comprehensively as possible at the beginning of design. The mold manufacturing process is also an important part to ensure the mold quality. The processing method and precision in the mold manufacturing process will also affect the service life of the mold. The accuracy of each component 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 process to improve the processing accuracy of the mold parts. The surface of the main forming parts of the die is strengthened to improve the surface wear resistance of the die parts, so as to improve the quality of the die. The correct use and maintenance of the mould is also a major factor to improve the quality of the mould.

For example, the installation and debugging methods of the mold should be appropriate. If there is a hot runner, the power wiring should be correct, the cooling water circuit should meet the design requirements, and the parameters of the injection molding machine, die-casting machine, and press machine in the production should conform to the design requirements. When using the mold correctly, it is also necessary to conduct regular maintenance for the mold. The guide pillar, guide sleeve and other parts with relative movement of the mold should be regularly filled with lubricating oil. For the forging mold, plastic mold, die-casting mold and other molds, the lubricant or mold lifting agent should be sprayed on the surface of the formed parts before each mold is formed.

With the development of society, more and more attention has been paid to the quality of molds. With the strengthening of mold design and manufacturing and the realization of new mold technology, more and more attention has been paid to mold quality. Quality is always a new topic, and the quality is improving with the improvement of mold technology.
