Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a plastic product processing mould. Background Art

[0002] Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material, including products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fiber, it forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, with various additives added. It can be molded into a certain shape under certain temperature and pressure conditions and keep its shape unchanged at room temperature.

[0003] When processing plastic products, the plastic needs to be heated and melted, then injected into a mold and cooled to form. When using existing processing molds, it is mostly inconvenient to evenly distribute the plastic solution inside the mold, which can easily lead to incomplete injection molding of plastic products. In addition, when the plastic is easily injected, bubbles are easily generated in the solution, affecting the quality of the plastic products. Therefore, we propose a plastic product processing mold.
