[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] A mold for processing automobile headlight caps, see Figures 1 to 4 , comprising a base 1, an injection molding mechanism 2 is provided on the top of the base 1, a mold assembly 3 is provided inside the injection molding mechanism 2, a cooling mechanism 4 is provided inside the base 1, and a lamp holder forming part 5 is provided inside the mold assembly 3;

[0025] The mold assembly 3 includes a card plate 301, which is engaged with the inner side of the surface of the injection molding mechanism 2. A plurality of mold columns 302 are arranged on the top of the card plate 301. A buckle groove 303 is opened in the middle of the front and rear ends of the card plate 301. A left mold 304 is arranged on the left side of the mold column 302, and a right mold 305 is arranged on the right side of the mold column 302. The mold column 302 is inserted into the mold groove between the left mold 304 and the right mold 305. The gap between the mold column 302 and the mold groove constitutes a cavity. The left mold 304 and the right mold The surface of one side of 305 away from the mold column 302 is fitted with a positioning plate 306, and the positioning plate 306 is connected to the left mold 304 and the right mold 305 by bolts 307. Furthermore, the bottom of the left mold 304 and the right mold 305 is fitted with the surface of the clamping plate 301, and the left mold 304 and the right mold 305 form a detachable structure with the positioning plate 306 through bolts 307. The side of the positioning plate 306 away from the left mold 304 and the right mold 305 is connected to an electric push rod 308. The utility model uses an electric push rod 308 to effectively drive the left mold 304 and the right mold 305 to translate toward the mold column 302, and the fitted left mold 304 and right mold 305 together form a mold groove, so that the gap between the mold column 302 and the mold groove constitutes a cavity. After injection and cooling, the electric push rod 308 effectively drives the left mold 304 and the right mold 305 away from the mold column 302, so that the lamp holder molded part 5 is exposed. At this time, the lamp holder molded part 5 can be directly moved upwards, which is relatively fast and convenient. The mold column 302, the left mold 304 and the right mold 305 can all be disassembled and replaced, thereby improving the practicality of the device.

[0026] It is worth noting that the injection molding mechanism 2 includes a bracket 201, the bracket 201 is fixed to the top of the base 1, two groups of hydraulic cylinders 202 are arranged on the surface of the bracket 201, the movable end of the hydraulic cylinder 202 is connected to a top plate 203, a hot runner 204 is arranged on the top of the top plate 203, and a nozzle 205 is arranged at the bottom of the hot runner 204. In the utility model, the hydraulic cylinder 202 effectively drives the top plate 203 to move up and down. When the top plate 203 moves down to fit the top of the left mold 304 and the right mold 305, the molten liquid in the hot runner 204 can be sprayed into the cavity through the nozzle 205. When the top plate 203 moves up, it is convenient to provide a space for the lamp holder molding 5 to move out.

[0027] It is worth mentioning that the cooling mechanism 4 includes a water cooling box 401, which is engaged with the inside of the base 1, and a water pump 402 is provided on the front end surface of the water cooling box 401, and a group of water inlet pipes 403 are provided on the surface of the water pump 402, and a group of water outlet pipes 404 are provided on the rear end surface of the water cooling box 401, wherein the water inlet pipe 403 and the water outlet pipe 404 contain a section of foldable telescopic tube body, and hollow grooves are opened inside the left mold 304 and the right mold 305, and the water inlet pipe 403 is connected with the water outlet pipe 404 through the hollow groove. After the injection molding in the utility model is completed, the cold water inside the water cooling box 401 is effectively pumped from the water inlet pipe 403 to the hollow grooves opened inside the left mold 304 and the right mold 305 by the water pump 402, so as to cool the left mold 304 and the right mold 305, thereby cooling the lamp holder molding 5 and accelerating the cooling speed of the lamp holder molding 5. The water after heat exchange enters the water cooling box 401 from the water outlet pipe 404 for re-cooling and recycling.

[0028] Working principle: The electric push rod 308 drives the left mold 304 and the right mold 305 to move horizontally toward the mold column 302, and the left mold 304 and the right mold 305 that fit together form a mold groove, so that the gap between the mold column 302 and the mold groove forms a cavity, and then the hydraulic cylinder 202 drives the top plate 203 to move downward. When the top plate 203 moves downward to fit the top of the left mold 304 and the right mold 305, the nozzle 205 can spray the molten liquid in the hot runner 204 into the cavity, and then the water pump 402 pumps the cold water inside the water cooling box 401 through the water inlet pipe 403 to the left mold 3 04. In the hollow groove opened inside the right mold 305, the left mold 304 and the right mold 305 are cooled down, thereby cooling the lamp holder molded part 5 and accelerating the cooling speed of the lamp holder molded part 5. The water after heat exchange enters the water cooling box 401 through the outlet pipe 404 for re-cooling and recycling. After the injection molding and cooling are completed, the top plate 203 moves up to provide a removal space for the lamp holder molded part 5. Then, the electric push rod 308 drives the left mold 304 and the right mold 305 away from the mold column 302 to expose the lamp holder molded part 5. At this time, the lamp holder molded part 5 can be directly moved upward, which is relatively quick and convenient.
