[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] According to a publicized injection mold with rapid demolding (publication number: CN214324085U), the injection mold with rapid demolding described in the above application can quickly close and demold the front mold and the rear mold through the principle of screw drive. While demolding is fast, it has a good protective effect on the product and prevents product damage.

[0004] However, in actual use, when the front and rear molds of the above-mentioned equipment are separated, the mold is pulled by the hydraulic devices at both ends of the mold body. However, the left and right sides of the mold body lack corresponding restraint structures. When demolding, the mold may move with the front or rear mold and tilt, which will damage the mold body. In view of this, we propose an injection mold that can avoid damage to the workpiece. Utility Model Content
