Embodiment Construction

[0016] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0017] The new type of injection mold according to the present invention includes a pouring system. The pouring system includes an injection main runner and several injection runners. The injection runner port is a tapered hole and the bottom opening is larger than the top. The injection runners are connected In the cavity, the outer wall of the injection sprue is provided with bolts, the inner wall is provided with a number of path baffles, a spherical mechanism is provided at the midpoint of the edge of the path baffle, and the other end of the spherical mechanism is provided with an adjustment handle, A circular casing is provided on the outside, and the surface of the circular casing is provided with four opposite openings, and two of the opening walls are provided with threads.

[0018] In this embodiment, the inner wall of the injection main runner port is strea...

Abstract

The invention discloses a novel injection mold. The novel injection mold comprises a casting system; the casting system comprises an injection molding main runner and multiple injection molding branchrunners; a port of the injection molding main runner is a conical hole, and the bottom end opening diameter is larger than the top end; and the injection molding branch runners communicate with a molding cavity. The novel injection mold is characterized in that multiple path baffle plates are arranged on the inner wall of the injection molding main runner; spherical mechanisms are arranged in theedge middle points of the path baffle plates; adjusting handles are arranged at the other ends of the spherical mechanisms; a circular outer shell is arranged at the external; and four opposite openings are formed in the surface of the circular outer shell. The path baffle plates are arranged on the inner wall of the injection molding main runner; the material flow can be adjusted from the injection molding main runner to buffer and decelerate materials; meanwhile, a spraying material flowing path can be changed, and the materials can be injected in the appointed injection molding branch runners to effectively prevent the material waste phenomenon; and the inner wall of the port of the injection molding main runner is streamlined, so that the material attached on the wall can be easily agglomerated as drops to save the cost.

Description

Technical field [0001] The invention relates to the field of molds, in particular to a new type of injection mold. Background technique [0002] An injection mold is a mold used when the injection molding method is used. Injection molding refers to a method in which materials melted by heat are injected into a mold cavity by high pressure, and after cooling and solidification, a molded product is obtained. Injection mold refers to a device that obtains a product with a certain shape after resin material is injected into a metal mold. [0003] In the prior art, a bolt valve is generally used in the injection molding runner to adjust the flow rate of injection molding, but it will cause a waste of raw materials. With the increase of the injection molding runner, there are relatively more bolts and the structure is more complicated. Inconvenient to come. Summary of the invention [0004] In order to solve the above-mentioned related problems, the present invention provides a novel i...
