A kind of injection mold and the demoulding method of this mold

Abstract

The invention provides an injection mold and a demoulding method of the mold. A formed plastic product in the mold can be rapidly and effectively separated from the mold through the injection mold. The demoulding method comprises the following steps that firstly, a front mold block and a rear mold block on the outer surface of the formed plastic product are separated and located at the two ends of a through hole in a mold base; secondly, a core mold block on the inner surface of the formed plastic product is moved to the position above the through hole, and the plastic product moves to the position above the through hole along with the core mold block; thirdly, a push rod of the core mold block moves forwards relative to a sleeve of the core mold block, the sleeve can be telescopically connected with the push rod, two side blocks, hinged to the sleeve, of the core mold block move forwards along with the push rod, and meanwhile the two side blocks contract towards the inner side under pulling of the sleeve; and fourthly, the plastic product is separated from the core mold block and falls down from the through hole.

Description

technical field [0001] The invention relates to an injection mold and a demoulding method of the mold. Background technique [0002] The existing demoulding methods for injection molds on the market are generally only suitable for plastic products with simple inner surface structures, but it is difficult to achieve automatic demoulding for plastic products with complex surface structures, resulting in the need to manually remove plastic products from the mold Take out, reducing production efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide an injection mold capable of realizing automatic demoulding of plastic products, and a demoulding method of the mold. [0004] In order to achieve the above object, the invention provides a kind of injection mold, and it is used for molding a plastic product, and injection mold comprises: [0005] a base, the middle of which forms a through hole; [0006] The mold part includes a fron...
