Automatic demolding ejection type slide-free injection mold

Abstract

The invention discloses an automatic demolding ejection type slide-free injection mold. The automatic demolding ejection type slide-free injection mold comprises a fixed mold, a movable mold and a base, wherein the upper end of the base is connected with the bottom of the movable mold through a plurality of telescopic rods; an ejection rod is fixed at the upper end of the base; a plurality of groups of cooling mechanisms are arranged on the side wall of the movable mold; each cooling mechanism comprises a cooling cavity formed in the side wall of the movable mold and a heat dissipation box embedded in the side wall of the movable mold; a heat dissipation pipe communicating with the interior of the cooling cavity is arranged on the side wall of the heat dissipation box in a penetrating andinserting mode; and one-way valves are arranged at the two ends of the heat dissipation pipe. The automatic demolding ejection type slide-free injection mold has the advantages that a pressing block and a supporting plate are arranged, so that the pressing block and the supporting plate form a reserved space in a receding groove; and after cooling, an embedded material connected with a workpiece is reserved in the space, in the downward moving process of the movable mold, the embedded material and the pressing block are kept in a comprehensive abutting state, so that the workpiece can smoothlymove downwards along with the movable mold and is separated from the fixed mold, the mold opening action is completed, and the arrangement of an existing embedded block and a slide is replaced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an automatic demoulding ejection type injection mold without row positions. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain required products. Molds generally include two parts: moving mold and fixed mold. It can be separated or combined, take out the parts when separated, and inject the blank into the mold cavity to form when closed; [0003] In order to facilitate the demoulding of the whole, the existing injection molds are generally equipped with a row position and an insert mechanism to limit the position of the workpiece and facilitate the demoulding of the workpiece following the mold. In order to avoid collisions when the mold is closed, an additional reset is required. The mechanism helps to ...
