Problems solved by technology

The structure of the general thin-walled shell is complicated, and some have multiple buckle slots for installation. Due to the uneven cooling and heat during the injection molding process, the wall thickness of the injection molded part is uneven, and the thin-walled shell is easy to buckle during the demoulding process. , the buckle is easy to break, and it is not easy to demould, which reduces the product quality and increases the manufacturing cost. The production efficiency is low, and it is not suitable for large-scale promotion and use.

Abstract

The invention discloses an injection mould convenient for demoulding. The injection mould comprises an upper fixed plate and a lower fixed plate arranged under the upper fixed plate. The lower surface of the upper fixed plate is connected to a fixed mould plate. The lower surface of the fixed mould plate is provided with a fixed mould core. A moving mould plate is arranged on the lower fixed plate. A moving mould core is arranged on the upper surface of the moving mould plate. The moving mould plate and the fixed mould plate are selectively combined. The injection mould is characterized in that a runner is arranged in corresponding positions of the upper surface of the fixed mould plate and the fixed mould core. The fixed mould core and the moving mould core are combined to form a cavity of an injection mould for injection moulding. The provided injection mould can improve the demoulding efficiency, production efficiency, and injection mould quality, and reduce the production cost.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold that is easy to demould. Background technique [0002] Injection molding is a processing method used in the mass production of some complex structural parts, specifically refers to the injection of heated and melted materials into the mold cavity by high pressure, and the molded products after cooling and solidification. The most critical part in the injection molding process is the injection mold. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the fixed mold are separated to take out the plastic product when the mold is opened. Injection...
