Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to an injection mold, in particular to an injection mold that is easy to maintain. Background Art

[0002] Injection molds are an indispensable and important tool in the plastics processing industry. They are mainly used to produce various plastic products with complex shapes. When injection molds are used in conjunction with injection molding machines, highly efficient automated production can be achieved. The opening and closing of the mold, injection of plastic, cooling and ejection processes can all be completed through mechanical automation.

[0003] The reset rod in the injection mold is an indispensable component. It ensures the stable operation of the mold and the high-quality production of injection molded products by providing functions such as limiting, positioning, supporting and adjusting. Wear of the reset rod will lead to inaccurate mold reset. During the injection molding process, the reset rod plays an important role in ensuring that the mold opens and closes in place and maintains a stable position. If the reset rod is severely worn, the mold may deviate when opening and closing, resulting in unstable size of the plastic product and even possible shape deformation. This will not only reduce the quality of the plastic product, but also increase the scrap rate. Summary of the Invention
