Injection mold with automatic sprue residual material removing function

Abstract

The invention discloses an injection mold with an automatic sprue residual material removing function. The injection mold comprises a fixed mold plate, a sprue runner with a downward opening is formed in the fixed mold plate, a sealing plate cavity is formed in the left end wall of the sprue runner in a communicating mode, a sealing plate nut cavity is formed in the upper end wall of the sealing plate cavity in a communicating mode, a left line wheel cavity is formed in the left side of the sealing plate nut cavity, a sealing plate belt wheel cavity extending backwards is formed in the right side of the sealing plate nut cavity, and the left end wall of the sealing plate belt wheel cavity is connected with a sealing plate lead screw in a running fit mode, wherein the sealing plate lead screw extends rightwards into the sealing plate belt wheel cavity, penetrates through the sealing plate nut cavity leftwards and extends leftwards into the left line wheel cavity. After an automatic induction cavity is filled with hot melt plastic, the lower side of the sprue runner is blocked by the sealing plate, and injection molding residual materials are pushed out, so that automatic cleaning of the sprue runner residual materials after injection molding is achieved, the workload of operators is reduced, the production efficiency is improved, and the residual material cleaning effect is better; and in addition, the work of cutting off sprues after plastic parts are formed is omitted, so that materials are saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the related technical field of injection molds, in particular to an injection mold with the function of automatic removal of gate residual material. Background technique [0002] In injection molding, it is necessary to use the sprue to input hot-melt plastic to form the plastic part, but if the operation is improper, the residual material is easy to remain in the sprue, so it is often necessary to manually clean the sprue, which not only increases the workload of the operators, but also reduces the cost. Production efficiency, and the effect of manual cleaning is not good. In addition, after the plastic part is formed, the gate needs to be manually removed, which increases the burden on workers and the production cost of the enterprise, and causes a certain waste of raw materials.
