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.
For example, the equipment debugging mode of the mold should be appropriate. In the case of warm runner, the power wiring should be correct, the cooling water path should meet the planning requirements, and the parameters of the injection molding machine, die-casting machine and press in the production of the mold should match the planning requirements, etc. In the correct use of the mold, it is also necessary to carry out timely maintenance of the mold. The guide post, guide sleeve and other parts with relative motion of the mold shall be frequently filled with lubricating oil. For the forging die, plastic die, die-casting die and other molds, the lubricant or mold lifting agent shall 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 mold. With the strengthening of planning and manufacturing of mold, the realization of new mold skills, more and more attention has been paid to the quality of mold. Quality is always a new topic. Quality is advancing with the change of mold skills.
