[0002] In the processing of battery vehicle lights, it is necessary to install corresponding headlight covers to gather light for use, and mold injection molding is often used for processing and manufacturing of the headlight covers, and demolding is often inconvenient during the injection molding process; Patent No. CN202222688832.X discloses an injection mold for the production of electric vehicle headlight covers, including a fixed plate, an electric push rod is fixedly installed at the top center of the fixed plate, and the top of the electric push rod is fixedly connected to a movable plate; a limit spring is fixedly installed on both sides of the movable plate, and the movable plate is elastically connected to the fixed plate through the limit spring; a lower mold is fixedly connected to the left top of the movable plate; a demolding structure is symmetrically installed inside the lower mold, and an upper mold is correspondingly arranged on the top of the lower mold; a feed port is opened inside the center of the upper mold. The injection mold for producing the electric vehicle lamp cover, after injection molding is completed, the movable plate moves down for demoulding, the motor drives the toothed plate to move through the gear, and then the fixed plate drives the movable plate to move, and then the replacement mold is moved to the bottom of the upper mold for injection molding, and then the lamp cover is taken out and the injection molding process is carried out at the same time, which reduces the waste of time and increases the efficiency of lamp cover processing.

[0003] The disadvantage of the above-disclosed injection mold is that during the injection molding process, the injected glue will cause the air inside the mold cavity to be discharged, so an exhaust needle needs to be designed. However, the traditional exhaust needle is embedded in the mold and is inconvenient to replace. Based on this, we design an injection mold for electric vehicle lights. Summary of the invention

[0020] The above-mentioned design utilizes the pressed and tilted connecting strip 17 to facilitate tilting out the metal exhaust needle 13 , so as to facilitate better removal of the metal exhaust needle 13 , and has good convenience.

[0021] refer to Figure 1 and Figure 3 As shown, in the present embodiment, a mold stabilizing assembly is provided on one side of the mold base 1, and the mold stabilizing assembly includes an L-shaped connecting seat 6, a horizontal connecting plate 9 and two telescopic cylinders 11, and the two telescopic cylinders 11 are embedded in the top of the L-shaped connecting seat 6, and connecting rods 8 are installed at the output ends of the two telescopic cylinders 11, and the two connecting rods 8 are connected to the bottom of the horizontal connecting plate 9; a strip groove 20 is provided at the top of the horizontal connecting plate 9, and a sliding member 21 is slidingly provided inside the strip groove 20, and an extension strip 10 is provided at the top of the sliding member 21, and the extension strip 10 is connected to the mold top plate 4.

[0022] The above-mentioned design can limit the side and top of the mold top plate 4 to avoid high pressure during injection, which will produce a large reaction force on the lower mold body 2 and the upper mold body 3 of the car light injection molding, thereby increasing the gap between the lower mold body 2 and the upper mold body 3 of the car light injection molding, effectively ensuring the injection molding accuracy.

[0023] In the present technical solution, further, in order to better blow-cool the side of the lower mold body 2 and the upper mold body 3 of the headlight injection molding, a blowing strip 7 is provided on the inner side of the L-shaped connecting seat 6, and the blowing strip 7 and the two telescopic cylinders 11 are connected to an external air source pump.
