[0002] An injection mold is a mold used in the injection molding process to produce a variety of plastic products, such as plastic parts, containers, toys, etc. Injection molds are usually composed of multiple components, including a mold base, a mold core, a mold cavity, etc. During the injection molding process, plastic particles are heated and melted and injected into the mold cavity. After a certain pressure and cooling time, the mold is opened and the molded plastic product is taken out. The design and manufacture of injection molds need to consider factors such as material fluidity, cooling time, and molding quality to ensure that the quality and shape of the final product meet the requirements. Injection molds are widely used in industrial production and are one of the key tools for the production of plastic products. The production of plastic bowls usually relies on injection molds.

[0003] However, in the process of removing the material from the traditional injection mold, the mold needs to be opened first, and then the plastic bowl needs to be removed from the mold cavity by a suction cup. The two actions are continuous rather than synchronous, so there are problems of low efficiency and long cycle, which reduces the injection efficiency of the plastic bowl. Utility Model Content
