Description

Technical Field

[0001] This utility model belongs to the field of automotive parts injection mold technology, and in particular relates to a double-piece injection mold for automotive headlight housing. Background Technology

[0002] As a crucial component of automobiles, automotive headlights typically rely on injection molds for their housing production. Currently, traditional automotive headlight housing injection molding largely follows a single mold production model for a single headlight housing (either the left or right headlight housing). This model requires separate molds for producing the left and right headlight housings, increasing both manufacturing and storage costs. Furthermore, the frequent mold changes during production reduce efficiency and fail to meet the demands of large-scale mass production.

[0003] To address the aforementioned issues, this invention proposes a dual-part injection mold for automotive headlight housings. By designing both the fixed mold and the moving mold as dual-part structures, it enables the simultaneous production of the left and right headlight housings, thereby improving production efficiency and reducing costs. Utility Model Content

[0004] The purpose of this utility model is to provide a double-piece injection mold for automotive headlight housings, thereby solving existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a double-panel injection mold for automotive headlight housing, comprising a fixed mold assembly and a moving mold assembly, both of which are double-panel structures;

[0007] The fixed mold assembly includes a left fixed mold and a right fixed mold, which are fixedly connected. The left fixed mold has a left fixed mold cavity, and the right fixed mold has a right fixed mold cavity.

[0008] The moving mold assembly includes a left moving mold and a right moving mold, which are fixedly connected. The left moving mold is provided with a left moving mold core that cooperates with the left fixed mold cavity, and the right moving mold is provided with a right moving mold core that cooperates with the right fixed mold cavity.

[0009] In one embodiment, when the fixed mold assembly and the moving mold assembly are closed, the left fixed mold cavity and the left moving mold core form the injection cavity of the left headlight housing, and the right fixed mold cavity and the right moving mold core form the injection cavity of the right headlight housing. The two injection cavities are respectively connected to the discharge port of the injection molding machine through their respective runners.

[0010] In one embodiment, the fixed mold component and the moving mold component have the same dual-structure.

[0011] In one embodiment, a connecting groove adapted to the connecting clip is provided at the junction of the left fixed mold and the right fixed mold. The connecting groove is a "U" shaped groove. A positioning groove is provided in the middle of the connecting groove. A positioning block is provided in the positioning groove. Mounting screw holes matching bolts are provided in the connecting grooves on both sides of the positioning groove.

[0012] In one embodiment, the shape and size of the connecting slot are adapted to the connecting clip, and the connecting slot and the connecting clip cooperate with each other.

[0013] In one embodiment, the shape and size of the positioning groove are adapted to the positioning block, and the positioning groove and the positioning block cooperate with each other.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model designs the fixed mold assembly as a double structure of left and right fixed molds, and the moving mold assembly as a double structure of left and right moving molds, which can simultaneously produce the left and right headlight housings, greatly improving production efficiency and reducing the time and cost of mold replacement.

[0016] 2. The left and right fixed molds, as well as the left and right moving molds, are precisely connected and positioned through the cooperation of connecting clips, bolts, positioning slots, and positioning blocks, ensuring the accuracy of mold assembly and thus ensuring the dimensional accuracy and quality stability of the left and right headlight housings produced by injection molding.

[0017] 3. The use of a dual-structure mold reduces the number of molds compared to separate left and right headlight housing molds, thereby lowering the manufacturing cost and storage space requirements, which helps companies control production costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
