Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1-Figure 4 , the embodiment of the present invention provides an injection mold (corresponding to the mold according to the present invention), which can be reduced as figure 1 The deformation of the injection molded part shown (corresponding to the molded part according to the invention) thus increases the production yield of the injection molded part.

[0032] The injection mold that the embodiment of the present invention discloses is used for producing such as figure 1 The injection molded part shown, as described in the background art, figure 1 The injection molded part described in includes a bottom plate 01 and a support plate 02 perpendicular to the bottom plate 01 .

[0033] The disclosed injection mold ...

Abstract

The invention provides a mould for producing moulded pieces. The mould comprises sliding blocks for limiting at least a part of a moulded cavity; each of the sliding blocks can slide between a first position and a second position; the first positions correspond to a die closing state of the mould; and the second positions correspond to a die opening state of the mould. The mould further comprises pushing components arranged in the sliding blocks; the pushing components are able to move relative to the sliding blocks, so that at least in the early stage of a sliding process during which the sliding blocks slide to the second positions from the first positions, the pushing components are abutted against the moulded pieces and do not move with the sliding blocks integrally. According to the mould, the problem that the yield is low due to the fact that the deformation of the moulded pieces produced at present is large can be solved.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a mould, which is improved in preventing deformation of molded parts. Background technique [0002] Injection molded parts (molded parts) are relatively common structural parts and are widely used in products. Injection molded parts are made of integral injection molding of plastic, which has the advantages of fast processing and high strength. Since the injection molded part is formed by pouring the plastic into the cavity of the mold after being heated and then cooled, the shape stability of the injection molded part is the bottleneck of the product quality. How to improve the shape stability of injection molded parts is the current research direction of mold developers. [0003] Please refer to figure 1 , figure 1 It is a common injection molded part structure, and the injection molded part includes a base plate 01 and a support plate 02, and the support plate 02 is arranged on the b...
