DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The following will be combined Figure 1-Figure 4 The injection mold of the vehicle lamp housing according to the embodiment of the utility model is described in detail.

[0020] Example:

[0021] The lamp housing injection mold provided by the utility model embodiment refers to Figures 1 to 4 As shown, it includes a base plate 1, a lower mold base 2 is fixedly installed on the base plate 1, a lower injection mold body 3 of a headlight housing is arranged on the lower mold base 2, a bracket 8 is fixedly connected to the base plate 1, a hydraulic rod 29 is fixedly installed on the top of the bracket 8, a lifting plate 10 is fixedly installed on the piston rod end of the hydraulic rod 29, and an upper injection mold body 11 of the headlight housing is fixedly installed on the bottom of the lifting plate 10. In this structure, the hydraulic rod 29 drives the upper injection mold body 11 of the headlight housing on the lifting plate 10 to move downward, thereby merging with the lower injection mold body 3 of the headlight housing on the lower mold base 2, and then the headlight can be injection molded.

[0022] refer to Figures 1 to 4 As shown, the four end corners of the lifting plate 10 are slidably connected with guide rods 12, the lower ends of the guide rods 12 are fixedly mounted on the base plate 1, and the lower ends of the guide rods 12 are fixedly mounted on the bracket 8. This structure uses the guide rods 12 to guide the up and down movement of the lifting plate 10, thereby guiding the up and down movement position of the injection mold 11 on the lamp housing.

[0023] refer to Figures 1 to 4 As shown, the two front side walls of the lower injection mold 3 of the lamp housing are fixedly connected with shaft rods 4, and the shaft rod 4 is rotatably connected to the lower mold base 2. The two rear side walls of the lower injection mold 3 of the lamp housing are fixedly connected with push rods 5. The two front side walls of the lower mold base 2 are fixedly connected with pillars 6. The pillars 6 are rotatably connected with hydraulic rods 7. The piston rod end of the hydraulic rod 7 is rotatably connected to the push rods 5. In this structure, the lower injection mold 3 of the lamp housing can be rotatably connected on the lower mold base 2 through the shaft rod 4. When it is necessary to clean or take materials from the lower injection mold of the headlight housing, the personnel can start the hydraulic rod 7 on the pillar 6 to extend the push rod 5, and the push rod 5 pushes the lower injection mold 3 of the headlight housing to flip in front of the lower mold base 2, so that the lower injection mold 3 of the headlight housing is erected, which is convenient for personnel to take the materials and clean the lower injection mold 3 of the headlight housing. When taking materials and cleaning with this structure, personnel will not put their hands between the upper and lower injection molds, and the use and maintenance of the mold will be safer.

[0024] refer to Figures 1 to 4 As shown, a concave groove 13 is provided on the lower mold base 2 , and the lower injection mold body 3 of the lamp housing is embedded in the concave groove 13 . This structure utilizes the concave groove 13 to facilitate the lower injection mold body 3 of the lamp housing to be received into the lower mold base 2 .

[0025] refer to Figures 1 to 4As shown, two arc-shaped positioning grooves 14 are provided on the rear side of the lower mold base 2, and the arc-shaped positioning grooves 14 are adapted to be snap-fitted with the push rod 5. When the lower injection mold body 3 of the lamp housing is used horizontally, the push rod 5 can be snapped into the arc-shaped positioning grooves 14, thereby limiting the position of the push rod 5, thereby positioning the lower injection mold body 3 of the lamp housing, thereby ensuring that the upper and lower mold bodies are accurately merged during the later injection molding of the lamp.

[0026] It should be noted that the injection mold in the above embodiment is used for injection molding of the headlight shell, which belongs to the field of headlight injection molding equipment, and the specific mold structure and mold cooling pipeline of the above-mentioned lower injection mold 3 of the headlight shell and the upper injection mold 11 of the headlight shell have been disclosed, and this application does not improve the specific structure of the lower injection mold 3 of the headlight shell and the upper injection mold 11 of the headlight shell, so it will not be elaborated here.

[0027] The implementation principle of the injection mold for the headlight housing in the embodiment of the present application is as follows: when it is necessary to remove materials or clean and maintain the lower injection mold of the headlight housing, personnel can start the hydraulic rod 7 on the pillar 6 to extend the push rod 5, and the push rod 5 pushes the lower injection mold 3 of the headlight housing to flip in front of the lower mold base 2 through the shaft 4, so that the lower injection mold 3 of the headlight housing is erected, which is convenient for personnel to take the materials and clean the lower injection mold 3 of the headlight housing. When removing materials and cleaning this structure, personnel will not put their hands between the upper and lower injection molds, and the use and maintenance of the mold will be safer.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
