Description

Technical Field

[0001] The utility model relates to an injection molding process technology, in particular to a two-color injection molding of soft and hard plastic automobile parts. Background Art

[0002] Two-color injection hard and soft plastic parts are special plastic products made by two-color injection molding technology. They combine the characteristics of hard plastic (usually rigid, high-strength plastic) and soft plastic (usually soft, elastic plastic). Nowadays, many car models have begun to use two-color injection products. Two-color injection molding refers to the molding process of injecting two different materials into the same mold, so that the injection molded parts are formed by two materials. Some of the two materials are different colors, and some are different in hardness and softness, thereby improving the aesthetics and assembly performance of the product. However, if the appearance of the two-color product itself is not good, it will not only fail to improve the aesthetics of the whole vehicle, but will even affect the aesthetics of the whole vehicle, which will directly reduce the consumer's desire to buy, thereby greatly reducing the value of the whole vehicle.

[0003] In two-color injection molding, hard glue is usually injected first, and then soft glue is injected. When injecting soft glue, the hard mold will be offset due to excessive pressure, which will cause the hard glue to be pulled or scraped.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a two-color injection molding of soft and hard plastic automobile parts to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A two-color injection-molded soft and hard plastic automobile part, comprising a soft plastic part and a hard plastic part, wherein a mounting groove is provided on opposite sides of the soft plastic part and the hard plastic part, and the hard plastic part contacts the inner wall of the mounting groove of the soft plastic part;

[0008] A connecting plate is fixedly connected to the inner wall of the installation groove of the hard plastic part, one end of the connecting plate is fixedly connected to the inner wall of the installation groove of the soft plastic part, and an art groove is opened at the junction of the soft plastic part and the hard plastic part.

[0009] Furthermore, in order to increase the strength and stability between the hard plastic parts, a plurality of reinforcing ribs are fixedly provided below the hard plastic parts, and a plurality of reinforcing plates are fixedly connected to opposite sides of every two reinforcing ribs.

[0010] Furthermore, in order to better assist the reinforcing ribs and improve the strength of the hard plastic parts, auxiliary frames 1 are fixedly installed at both ends of two of the reinforcing ribs, and auxiliary frames 2 are fixedly installed at one end of the other two reinforcing ribs, and parts of auxiliary frames 2 and 1 are fixedly connected to the hard plastic parts.

[0011] Furthermore, a plurality of auxiliary balls are arranged below the auxiliary frame 1.

[0012] Furthermore, in order to reinforce the structure or provide an additional support surface, a plurality of auxiliary plates are fixedly disposed below the hard plastic member, and one side of the auxiliary plate is close to one side of the second auxiliary frame.

[0013] Furthermore, an auxiliary groove is provided on one side of the hard plastic part.

[0014] The beneficial effects of the utility model are:

[0015] (1) By reserving the sealing position of the soft and hard plastic parts with the art groove, it can not only effectively solve the problem of the hard mold being offset due to excessive pressure, causing the hard plastic to be pulled and scraped, but also help to reserve a large debugging space for the process, and can also reduce the cracking of the soft and hard plastic joint position caused by poor bonding due to the thin edges.

[0016] (2) By coordinating the reinforcing ribs provided on the hard plastic parts with the reinforcing plates, it is possible to reduce the situation where the hard plastic parts cannot be fixed by a single ordinary reinforcing rib and to avoid instability in the production process caused by extreme processes.
