A kind of injection mold device

Abstract

The invention relates to the technical field of injection molding, and discloses an injection mold device, which includes an injection gun head, a fixed mold, a movable mold and a hydraulic cylinder. The inner wall of the bottom surface is fixedly connected with a set of springs A, and the ends of the two sets of springs A away from the inner wall of the plastic guide tube are fixedly connected with a clamp block. The side of the plastic guide tube away from the injection gun head is fixedly connected with the fixed mold, and the upper and lower ends of the fixed mold side Both sockets A are provided, and inserting rods are sleeved in the two sockets A. The left ends of the two inserting rods are fixedly connected to the movable mold. The corresponding sides of the inserting rod and the movable mold are provided with mold cavities. The pressure makes the circulating cooling pipe separate from the fixed mold and the movable mold, avoiding the cooling of the raw material during the injection molding process, resulting in increased resistance or even blockage, and the circulating cooling pipe is automatically connected to the fixed mold and the movable mold after the injection molding is completed, so as to ensure the cooling of the raw material forming.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection mold device. Background technique [0002] Injection molding is a method for the production and modeling of industrial products. After combining two molds with a power source such as a hydraulic cylinder, the melted plastic raw materials are injected into the cavity for cooling and molding, so as to make various shapes of plastic products. [0003] The existing patent number CN107139398B proposes an injection mold, which has the advantage that the mold is less affected by temperature changes, but in the process of injection molding, it is unavoidable that two molds will be caused by maintenance errors or failure of the power source. The joint is not tight enough or has depressions. At this time, the injection of raw materials will lead to leakage. The leaked raw materials will accumulate in the gap between the two molds, and the two molds will stick togethe...

Problems solved by technology

[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
