Embodiment Construction
[0019] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as image 3 As shown, this application provides:
[0021] A mold device for solving the problem of secondary injection molding easily damaged plastic parts, including a female mold 1 and a male mold 6. The gap between the female mold 1 and the male mold 6 constitutes a cavity for inserting a hard rubber product 2 There is a mold cavity for forming the soft rubber product 3 between the hard rubber product 2 and the cavity, and the part facing the male mold 6 in the contact position between the female mold 1 and the hard rubber product 2 is replaced by an elastic member 7 .
[0022] Based on the above-mentioned embodiments, the technical problem that the present application intends to solve ...

The invention relates to the field of injection molds, in particular to a mold device for solving a problem that an appearance leather grain surface of a plastic part product is prone to being damaged by secondary injection molding. The mold device comprises a female mold and a male mold, wherein a gap between the female mold and the male mold forms a cavity used for accommodating a hard rubber product, a mold cavity used for forming a soft rubber product is formed between the hard rubber product and the cavity, and the part, facing the male mold, of the contact part of the female mold and the hard rubber product is replaced by an elastic piece. The elastic piece is used for replacing the female mold to be pressed on the surface of the hard rubber product, and the technical problem of how to prevent the iron female mold from crushing the surface of the hard rubber product during mold assembly during secondary injection molding of the soft rubber product is solved.
Description
technical field [0001] The invention relates to the field of injection moulds, in particular to a mold device for solving the problem of skin texture on the appearance of plastic parts easily damaged by secondary injection molding. Background technique [0002] The front windshield sealing strip product on the car is a secondary insert injection molding (ASA hard rubber + TPE soft rubber), and the formed parts (ASA hard rubber) need to be placed on the TPE soft rubber mold for injection molding. [0003] Such as figure 1 As shown, this type of windshield sealing strip product is a two-color molding product. Due to structural reasons, it cannot be formed by a conventional two-color mold, so it can only be molded by secondary insert injection molding. The method is to pass the hard rubber product with a good appearance Manual or mechanical hands are put back into the soft rubber mold for local overmolding, because the appearance surface will be directly pressed by the cavity ...
