[0002] Injection molds are tools used to produce plastic products; they also give them a complete structure and precise dimensions. Injection molding is a processing method used for mass production of complex parts. Specifically, the injection molding machine injects molten plastic into the mold cavity under high pressure. After cooling and solidification, the resulting molded product is formed. The mold frame is a crucial component of the mold, providing the necessary structure and support to ensure proper function during the injection molding process.

[0003] The existing mold frame for injection molds is mainly composed of a movable mold frame, a fixed mold frame, guide columns and guide sleeves. The movable mold frame slides on the guide columns under the drive of the hydraulic rod. Since the movable mold frame and the guide columns are in direct contact, when there is offset contact friction between the movable mold frame and the guide columns, it will cause wear of the movable mold frame, making the movable mold frame unable to match the fixed mold frame, thereby reducing the service life of the movable mold frame. For this reason, the present invention provides a guide mechanism for a mold frame for injection molds. Utility Model Content
