Their material selection, design, and manufacturing process are directly related to the quality, production efficiency, and cost of plastic products. The quality of mold design and manufacturing has a decisive impact on the accuracy, consistency, and production efficiency of the product.
[0003] Comparative Publication No. CN 213108030 U A plastic product production injection mold, including an upper mold, a lower mold plate, a support plate and a lower mold base, the base surface of the lower mold plate is provided with a molding cavity and a rectangular hole, the inner wall of the molding cavity is connected with a gear through a rotating shaft, the gear is meshed with a horizontally arranged movable rod, and is meshed with a vertically arranged driving rod, the base surface of the lower mold base is provided with a through hole, the bottom of the through hole is threadedly connected with a plug, and a spring is arranged inside, preferably, a convex mold core is fixedly arranged at the bottom of the upper mold, and the convex mold core is matched with the molding cavity, preferably, the support plate is fixedly connected to the bottom of the lower mold plate, and the lower mold base is fixedly connected to the bottom of the support plate, preferably, the The interior of the lower template is provided with a guide hole connected to the molding cavity, and the movable rod and the guide hole are slidably connected. Preferably, the base surface of the movable rod is provided with teeth meshing with the gear. The upper mold moves downward, pressing the drive rod to drive the gear to rotate, thereby driving the drive rod to move toward the interior of the molding cavity. The upper mold fits the top of the lower template, and plastic is injected into the molding cavity. The punch core cooperates with the molding cavity for injection molding. At the same time, under the action of the movable rod, the side of the plastic product is formed into a hole. After molding, the upper mold moves upward, and the drive rod moves upward under the action of the spring, thereby driving the gear to rotate, thereby driving the movable rod to be retracted from the molding cavity, and the molded part in the molding cavity can be taken out.
