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

Embodiment 1

[0038] Example 1: Please refer to Figure 1-7 , an injection mold device, including an injection gun head 1, a fixed mold 5, a movable mold 8 and a hydraulic cylinder 12, the injection gun head 1 is a hollow cylinder, and the outer wall of the right end of the injection gun head 1 is fixedly connected with a plastic guide tube 2, The plastic guiding cylinder 2 is in the form of a hollow rectangular body, the right side of the plastic guiding cylinder 2 is provided with a hole and the injection gun head 1 is located in the hole, the top surface and the inner wall of the bottom surface of the plastic guiding cylinder 2 are fixedly connected with a set of springs A3. One end of the group spring A3 away from the inner wall of the plastic guiding cylinder 2 is fixedly connected with a clamping block 4, the clamping block 4 is in the shape of a quarter ellipsoid, and the front and rear walls and the left and right wall surfaces of the clamping block 4 are attached to the inner wall o...

Embodiment 2

[0045] Example 2: Please refer to Figure 8-9 , On the basis of the first embodiment, the transmission shaft of the hydraulic cylinder 12 is fixedly connected with a connecting plate 27, and a detection sensor 28 is fixedly installed on the connecting plate 27, and the detection sensor 28 corresponds to the position of the outer frame 82. The detection sensor 28 is used to detect the position of the outer frame 82, so that when the outer frame 82 is out of contact with the fixed mold 5 during the injection molding process, a signal is sent in time to cooperate with the control circuit to alarm and retract the drive shaft of the hydraulic cylinder 12.

[0046] A detection cylinder 29 is fixedly connected to the right side of the piston rod 15. The detection cylinder 29 is a hollow convex body. A thermometer 30 is fixedly installed in the detection cylinder 29. Set the temperature of the injection gun head 1 to detect the temperature of the injection gun head 1, so as to prevent...

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...
