Liquid plastic mold is a supporting product for liquid plastic bottle molding. The quality of the mold will directly affect the molding effect of the liquid plastic bottle. So, how to improve its quality?

1. The design of the mold should be reasonable, and the optimal structural scheme should be selected as much as possible for manufacturing. The designers should fully consider the technical requirements of the mold and the feasibility and craftsmanship of its structural design.

2. For the design of the mold, it is the key link to improve the overall quality of the mold, and we need to fully consider all aspects of the influencing factors. It mainly includes the selection of mold materials, the usability and safety of mold structure, the processing performance of mold parts and the convenience of mold maintenance.

3. For the selection of plastic mold materials, it is necessary to consider not only meeting the actual requirements of customers, but also material costs and other issues. In addition, it is also necessary to choose according to factors such as the type of mold, the way of use, and the processing speed.

4. In the mold structure design stage, the structure should be designed as compact as possible, easy to operate, and at the same time, the mold parts should have sufficient rigidity and strength. If the mold structure allows, the corner positions of each surface of the mold parts should be designed as rounded transitions as much as possible to avoid stress concentration. For the cavity, the die and a part of the core and punch, etc., a combined or inlaid structure can be used to eliminate the stress concentration phenomenon. For those slender punch or core parts, the structure needs to be Take appropriate protective measures. If it is a cold die, it should be equipped with a device that can prevent the workpiece or waste from clogging.
