Injection mold device

Abstract

The invention relates to the technical field of injection molding, and discloses an injection mold device. The injection mold device comprises an injection molding gun head, a fixed mold, a movable mold and a hydraulic cylinder; the outer wall of the right end of the injection molding gun head is fixedly connected with a plastic guide barrel, and the inner walls of the top face and the bottom faceof the plastic guide barrel are each fixedly connected with a spring A; clamping blocks are fixedly connected with the ends, away from the inner wall of the plastic guide barrel, of the two springs A; the face, away from the injection molding gun head, of the plastic guide barrel is fixedly connected with the fixed mold; insertion holes A are formed in the upper end and the lower end of the sideface of the fixed mold correspondingly; each inserting hole is provided with an inserting rod in a sleeved mode, and the left ends of the two inserting rods are fixedly connected with the movable mold; and mold cavities are formed in the faces, corresponding to the movable mold, of the inserting rods. A circulating cooling pipe is separated from the fixed mold and the movable mold through injection molding pressure, the problem that resistance is increased and even blockage is caused due to raw material cooling in the injection molding process is avoided, and the circulating cooling pipe is automatically connected with the fixed mold and the movable mold after injection molding is completed, so that cooling molding of the raw materials is ensured.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection molding mold device. Background technique [0002] Injection molding is a method of producing and modeling industrial products. After combining two molds with power sources such as hydraulic cylinders, the melted plastic raw materials are injected into the cavity for cooling and molding to make plastic products of various shapes. [0003] The existing patent No. CN107139398B proposes an injection mold, which has the advantage that the mold is less affected by temperature changes, but in the injection molding process, it is inevitable that due to maintenance errors or power source failures, two molds The junction is not tight enough or there is a depression. At this time, the injection of raw materials will cause leakage. The leaked raw materials will accumulate in the gap between the two molds, and after hardening, the two molds will stick together, resulti...

[0003] The existing patent No. CN107139398B proposes an injection mold, which has the advantage that the mold is less affected by temperature changes, but in the injection molding process, it is inevitable that due to maintenance errors or power source failures, two molds The junction is not tight enough or there is a depression. At this time, the injection of raw materials will cause leakage. The leaked raw materials will accumulate in the gap between the two molds, and after hardening, the two molds will stick together, resulting in damage to the tensile force generated when the power source pulls the mould. Equipment, and the process of separating and cleaning the two molds is extremely difficult, and the above molds have not been improved for the above conditions
