Description

An injection mold that is easy to maintain

Technical Field

The utility model relates to the field of injection molds, in particular to an injection mold which is easy to maintain.

Background Art

An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification.

The injection mold is divided into a movable mold and a fixed mold, and is installed above a support platform and a driving mechanism by bolts. However, after the current fixed mold is installed above the support platform, the bolts need to be removed before the fixed mold can be repaired, which does not achieve the effect of easy maintenance and reduces the maintenance speed of the injection mold. To this end, we propose an injection mold that is easy to maintain to solve the above problems.
