[0027] It should be noted that the utility model is a molding mold for producing automobile decorative strips. When in use, the lower mold 1 and the upper mold 2 are first installed in the injection molding machine respectively, and then the injection molding machine is started to drive the upper mold 2 to move downward to close the mold with the lower mold 1, and then the material is injected into the lower mold 1. After the decorative strip is formed, the injection molding machine is started to drive the upper mold 2 to move upward, and then the processed decorative strip can be removed. When the decorative strip is attached to the lower end of the upper mold 2 and cannot be demoulded normally, the hydraulic cylinder 5 is started, and the output end of the hydraulic cylinder 5 pushes the first movable plate 8 to move downward. During the movement, the first movable plate 8 pushes the second movable plate 9 and the push plate 15 downward through the telescopic spring 10. As the first movable plate 8 moves further, and one side of the lower end of the rotating frame 12 contacts the limit block 14, thereby pushing the rotating frame 12 to rotate.

During the processing of the lower mold 1, the coolant delivery pipe can be connected to the quick connectors 20 at both ends of the cooling pipe 18 respectively. During the circulation of the coolant in the cooling pipe 18, the heat conducting plate 19 can conduct the heat of the lower mold 1 to the inside of the cooling pipe 18 through the heat conducting gel 17, and dissipate the heat through the coolant, thereby effectively reducing the mold temperature and extending the service life of the mold. By setting up a demolding mechanism, the decorative strip stuck to the lower end of the upper mold 2 can be pushed out during the demolding process to prevent the decorative strip from adhering to the mold surface, speed up the demolding speed of the decorative strip, and improve the production efficiency of automobile decorative strips. By setting up a heat dissipation component, during the molding process, the heat of the mold can be conducted to the inside of the cooling pipe 18 through the heat conducting plate 19, and the heat is conducted away with the flow of the coolant, which can effectively reduce the mold temperature and extend the service life of the mold.
