Abstract

The invention discloses an ejection assembly of a mould and a demoulding method utilizing the ejection assembly. The mould is provided with a hollowed-out part, a part of the surface of a to-be-demoulded product is provided with a contact area and an edge area, the edge area is connected with the contact area, and the edge area is located at the edge of the contact area and internally provided with a positioning part. The ejection assembly comprises an ejector rod assembly and an ejector pin assembly, the upper end of the ejector rod assembly penetrates through the hollowed-out part, and the upper end face of the ejector rod assembly makes contact with the contact area. The top end of the ejector pin assembly makes contact with the positioning part. According to the ejection assembly of the mould, the ejector rod assembly is arranged to make contact with the contact area of the product, and the ejector pin assembly is arranged to make contact with the positioning part arranged in the edge area of the product so that the ejector rod assembly and the ejector pin assembly can be utilized to simultaneously push the to-be-demoulded product to move, the probability of local twist deformation or whitening of the to-be-demoulded product due to the fact that all parts of areas of the to-be-demoulded product cannot be demoulded simultaneously is decreased, and thus the product is protected against damage in the demoulding process.

Description

technical field [0001] The invention relates to an ejection structure of a mold, in particular to an ejection assembly of a mold and a demoulding method using the ejection assembly. Background technique [0002] Industrial production often uses molds as a tool for manufacturing shaped products to save energy while improving production efficiency. In the related art, the mold has an ejection structure, and a positioning structure adapted to the ejection structure is constructed on the molded product. The ejection structure can push the molded product to move to the outside of the mold by cooperating with the positioning structure, so as to complete the demoulding of the product. However, in related technologies, the positioning structure on the molded product will destroy the structural integrity of the molded product, resulting in a decrease in the structural strength of the molded product and affecting product quality. Contents of the invention [0003] The present appli...
