Dual-purpose plastic mold

Abstract

The invention discloses a dual-purpose plastic mold. The dual-purpose plastic mold comprises an upper mold plate and a lower mold plate; a mold cavity is formed in one face, opposite to the upper moldplate, of the lower mold plate; the upper mold plate comprises an upper mold plate body and a reinforcing plate, the reinforcing plate is movably placed on one side, opposite to the lower mold plate,of the upper mold plate; the upper mold plate body comprises a cavity base body and a core insert block; stop blocks which extend inwards are arranged on the inner sides of the two side walls of thecavity base body, the core insert block is arranged inside the cavity base body in a built-in mode, a convex part is arranged on one side, facing the reinforcing plate, of the core insert block, and the two sides of the convex part are arranged on the stop blocks in a clamped mode; and a plurality of longitudinal springs are installed between the core insert block and the inner top surface of thecavity base body at equal intervals. According to the dual-purpose plastic mold, through the structural design of an upper module, the size of the cavity of the plastic mold used for forming a plasticproduct can be changed, so that the forming requirements of the non-foamed plastic product and the foamed plastic product can be met, the application occasion of the mold is increased, the mold costis reduced, and the market prospect is wide.

Description

technical field [0001] The invention relates to a plastic mold, in particular to a dual-purpose plastic mold. Background technique [0002] With the advancement of science and technology and the development of society, people's demand for plastic products in daily life is increasing. Plastic products often need to be shaped by molds to achieve the required shape, so the use of plastic molds has also increased greatly. . [0003] In daily life, it is often necessary to use foamed plastic products. For the same plastic product, foamed products and non-foamed products have different requirements on the mold, among which, the most important thing is the different requirements on the filling amount in the mold during the molding process. At present, the industry uses different molds to produce foamed plastic products and non-foamed plastic products with the same structure, which causes a large number of molds to be hoarded, resulting in increased production costs.
