Description

Technical Field

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

[0002] Injection molds are tools used to manufacture plastic products. They play a key role in the injection molding process. Injection molds are usually composed of an upper mold and a lower mold. The upper mold is fixed on the fixed plate of the injection molding machine, and the lower mold is fixed on the movable plate of the injection molding machine. The structural design of the injection mold must take into account factors such as the shape, size and production process of the plastic product.

[0003] When the injection mold is used, if the injection mold is damaged inside, it needs to be disassembled to inspect and repair the inside. However, in order to ensure good injection molding, the injection mold is generally sealed and fixed, and it is difficult to disassemble it, which greatly affects the maintenance work of the mold. It cannot be disassembled and repaired quickly. In actual use, the existing injection molds have insufficient fixing stability and are difficult to adjust, which leads to low efficiency in injection molding production.

[0004] For this reason, an easy-to-fix injection mold is proposed. Utility Model Content
