[0002] The charging gun is a tool used to charge cars. In order to facilitate the use of operators, it is designed in the shape of a gun. The shell of the charging gun is usually made of plastic. Therefore, when processing the charging gun, an injection mold is required to process the shell of the charging gun.

[0003] Although there are many kinds of injection molds currently, there are still some problems. For example, the injection mold of the charging gun currently includes an upper mold, a lower mold and an injection port. When the charging gun needs to be processed, the upper mold and the lower mold can be closed, and then the molten plastic is injected into the injection port, and then the injection mold is cooled, so that the charging gun can be processed. In the prior art, the upper and lower molds need to be docked with each other before injection molding. However, due to the heavy weight of the template, auxiliary tools are needed to adjust the position of the two during docking, which is cumbersome, time-consuming and labor-intensive.

Both ends of the linkage rod 35 are rotatably connected to the connecting seat 34 provided on the first docking plate 31 and the support rod 33.

[0028] The driven adjustment unit includes a second docking plate 311, a second abutment seat 312 and a transmission rod 313. One end of the second docking plate 311 is rotatably connected to the side wall of the lower mold 1, and the second abutment seat 312 is fixed to the other end of the second docking plate 311. The transmission rod 313 is arranged between two adjacent second docking plates 311 and connected to the first docking plate 31.

[0029] The positioning and adjusting mechanism 3 is provided in the present invention, so that when the upper mold 2 is docked with the lower mold 1, the support rod 33 in the active adjustment unit can be driven to move by the gravity of the upper mold 2, and then the first docking plate 31 is driven to be synchronously linked by the linkage rod 35. When the first docking plate 31 rotates, the second docking plate 311 in the driven adjustment unit is synchronously linked by the transmission rod 313, so that the first abutment seat 32 and the second abutment seat 312 are respectively abutted against the side wall of the upper mold 2, and the position of the upper mold 2 is adjusted, so that the upper mold 2 can be quickly positioned and docked with the lower mold 1.

The elastic force of the return spring 39 enables the support rod 33 to be quickly reset.

[0034] See also Figure 1-Figure 4 In this embodiment, the first abutting seat 32 and the supporting seat 36 are both rotatably connected with an adjusting roller 310, and the upper mold 2 can move quickly when docking with the lower mold 1 through the rotation of the adjusting roller 310.

[0035] See also Figure 1-Figure 4 In this embodiment, the active adjustment unit is symmetrically arranged on the left and right sides of the lower mold 1, and the passive adjustment unit is symmetrically arranged on the front and back sides of the lower mold 1, so that when the upper mold 2 is docked with the lower mold 1, the upper mold 2 can be stressed all around and adjusted.

[0036] Working principle: When using the injection mold, first place the upper mold 2 on the lower mold 1. At this time, the upper mold 2 abuts against the supporting seat 36, and drives the support rod 33 to slide, and drives the first docking plate 31 to rotate through the support rod 33 and the linkage rod 35. When the first docking plate 31 rotates, the first docking plate 31 drives the second docking plate 311 to rotate synchronously through the transmission rod 313, so that the first abutting seat 32 and the second abutting seat 312 abut against the upper mold 2, and push the upper mold 2 to move, so that the upper mold 2 and the lower mold 1 can be quickly positioned and docked.

[0037] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
