The quality of plastic mold includes the following aspects:
(1) product quality: stability and consistency of product scale, surface finish of product, utilization rate of product data, etc;
(2) service life: under the premise of ensuring product quality, the number of working cycles that the mold can complete or the number of parts produced;
(3) application and maintenance of mould: whether it is the most convenient to use, simple to demould, and the production assistant time is as short as possible;
(4) repair cost, repair cycle, etc.
The fundamental way to improve the quality of mould: the planning of mould is the most important step to improve the quality of mould. Many factors need to be taken into account, including the selection of mould data, the usability and safety of mould structure, the machinability of mould parts and the convenience of mould repair, which should be considered as fully as possible at the beginning of the planning. The manufacturing process of mould is also an important part to ensure the quality of mould. The processing method and precision in the process of mould manufacturing will also affect the service life of mould. The accuracy of each part has a direct impact on the installation of the whole mold. In addition to the impact of the accuracy of the equipment itself, it is necessary to improve the processing methods of the parts and advance the skill level of the fitter in the process of mold grinding to advance the processing accuracy of the mold parts. In order to improve the wear resistance of the surface of the die parts, the surface of the main parts of the die is strengthened, and then the die quality is improved. The correct use and maintenance of the mold is also a major factor in advancing the quality of the mold.
