Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically to a plastic injection mold which is easy to assemble. Background Art

[0002] A plastic injection mold is a tool used to produce plastic products. It is one of the essential equipment in the plastic injection molding process. Specifically, a plastic injection mold is composed of two or more molds, which are used to inject heated and molten plastic raw materials into the mold. After a certain pressure and temperature treatment, it is cooled and solidified to form a plastic product.

[0003] In the process of plastic injection molding, the existing plastic injection mold usually needs to flexibly replace the mold plate to adjust according to the shape and size of the plastic product, so that it can be used for injection molding of various plastic products. However, when replacing the template with mold grooves of various shapes or sizes, personnel usually need to hold professional tools to disassemble and replace the template. However, this not only makes the entire replacement process more cumbersome, but also increases the labor burden of personnel, which brings great troubles to actual use.

[0004] Moreover, during the plastic injection molding process after mold injection, some plastic residues and other impurities are sometimes generated. If these residues are not cleaned up, it will affect the quality of the product for the next injection molding, and even cause defects or bubbles on the product surface. The existing cleaning method is usually that personnel manually clean the upper mold and the lower mold separately, which undoubtedly increases the workload of the personnel, and the cleaning efficiency is also low, causing many inconveniences to the use.

[0005] In view of this, we propose a plastic injection mold that is easy to assemble. Utility Model Content
