Abstract

The invention relates to an injection mold. The injection mold comprises a mold plate group and a molding mechanism, wherein the molding mechanism is arranged in the mold plate group; the molding mechanism comprises a pouring gate, a runner and a mold cavity; the mold cavity comprises a frame-shaped mold cavity for molding the periphery of a frame-shaped product; a connection passage is formed inside the mold cavity, two ends of the connection passage are respectively communicated with two opposite sides of the frame-shaped mold cavity, so as to mold ridges inside the frame-shaped product; the pouring gate is perpendicular to an extension plane of the mold cavity; the runner comprises a main runner and an auxiliary runner; the main runner is simultaneously communicated with the pouring gate and the frame-shaped mold cavity in one side of the connection passage, and one end of the main runner is provided with an oblique main intersection runner; one end of the auxiliary runner is provided with an oblique auxiliary intersection runner, and the other end of the auxiliary runner is communicated with the frame-shaped mold cavity in the other side of the connection passage; the main intersection runner and the auxiliary intersection runner span over the connection passage and are intersected. By adopting the injection mold, the utilization rate of raw materials is higher, and the waste of the raw materials can be effectively reduced.

Description

technical field [0001] The present disclosure relates to the field of product manufacturing, and in particular, to an injection mold. Background technique [0002] In the related art, when producing plastic products, injection molding is generally used for production. Some frame-shaped products, in addition to the four sides of the frame, have a rib in the frame as a reinforcing rib or divider. like figure 1 As shown, in the related art, when injection molding a product of this shape, it is generally necessary to use the form of double runners for injection molding. However, this injection molding method will cause more raw materials to remain in the runner, resulting in more waste. SUMMARY OF THE INVENTION [0003] To overcome the problems in the related art, the present disclosure provides an injection mold. [0004] According to an embodiment of the present disclosure, an injection mold is provided, including a template group and a molding mechanism, wherein the mol...
