Problems solved by technology

Due to the existence of the bayonet and hole structure, the existing demoulding structure is stuck by the bayonet when demoulding, and the demoulding cannot be performed normally.
If the mold is forcibly removed, it will cause damage to the product or the mold

Abstract

The invention discloses an injection mold release mechanism. The injection mold release mechanism comprises an upper mold (1) and a lower mold (2), wherein the upper mold (1) is arranged on the lowermold (2) in a sliding fit manner; a mold release mechanism body and a product support (3) are arranged on the lower mold (2), and the mold release mechanism body comprises a first auxiliary mold release mechanism, a second auxiliary mold release mechanism and a third auxiliary mold release mechanism; the first auxiliary mold release mechanism is arranged on the lower mold (2) in a sliding fit manner; the second auxiliary mold release mechanism is arranged on the lower mold (2) in a sliding fit manner; the third auxiliary mold release mechanism is fixed on the lower mold (2); the third auxiliary mold release mechanism is in sliding fit with the first auxiliary mold release mechanism, the third auxiliary mold release mechanism and the product support (3); the product support (3) forms a bottom shape of a product (4) with the first auxiliary mold release mechanism, the second auxiliary mold release mechanism and the third auxiliary mold release mechanism. The mechanism can effectively perform mold release on the product provided with bayonet and pore structures.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a demoulding mechanism for injection molds. Background technique [0002] Injection mold is a tool for producing plastic products. As the requirements of the product assembly process become higher and higher, the product structure tends to be more and more integrated and complex, which makes many products on the market add many complex structures to the original basis, such as bayonets, holes and other structures that are combined with each other. Due to the existence of the bayonet socket and the hole structure, the existing demoulding structure is stuck by the bayonet socket during demoulding, and the demoulding cannot be performed normally. If the mold is forcibly removed, it will cause damage to the product or the mold. Therefore, based on the above reasons, there is an urgent need for a demoulding mechanism for injection molds, which can effectively demould product...
