Further improvement is needed. For this reason, we propose a vehicle door frame sealing strip injection mold. Utility Model Content

[0005] The main purpose of the utility model is to provide an injection mold for a vehicle door frame sealing strip, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A vehicle door frame sealing strip injection mold comprises a bottom plate, a rotating component is installed at the lower end of the bottom plate, the upper end of the rotating component movably passes through the upper end of the bottom plate and is installed with two lower molds symmetrically distributed front and back, two guide columns are installed on the upper left and upper right parts of the bottom plate, a top plate is commonly installed on the upper ends of the four guide columns, a hydraulic cylinder is installed at the upper end of the top plate, the output end of the hydraulic cylinder movably passes through the upper end of the top plate and is fixedly connected to the upper mold, and a cooling component is installed at the front end of the top plate.

[0025] like Figure 1-Figure 4 As shown, a vehicle door frame sealing strip injection mold includes a base plate 1, a rotating component 10 is installed at the lower end of the base plate 1, the upper end of the rotating component 10 movably passes through the upper end of the base plate 1 and is installed with two lower molds 9 symmetrically distributed front and back, two guide columns 2 are installed on the upper left and upper right parts of the base plate 1, a top plate 4 is commonly installed on the upper ends of the four guide columns 2, a hydraulic cylinder 5 is installed on the upper end of the top plate 4, the output end of the hydraulic cylinder 5 movably passes through the upper end of the top plate 4 and is fixedly connected to the upper mold 7, and a cooling component 8 is installed at the front end of the top plate 4.

[0026] The rotating component 10 can improve work efficiency, reduce time waste, and increase production capacity. The specific structure is: the rotating component 10 includes a motor 101, and the motor 101 is a servo motor. The motor 101 is installed at the lower end of the base plate 1, and the output end of the motor 101 is transmission-connected with a connecting rod 102. The output end of the connecting rod 102 movably passes through the upper end of the base plate 1 and is fixedly connected with a rotating plate 103.

[0027] It takes a certain amount of time for the sealing strip to cool down naturally. In order to speed up the cooling of the sealing strip, the sealing strip is cooled by a cooling component 8. The specific structure is as follows: the cooling component 8 includes an L-shaped plate 81, which is installed at the front end of the top plate 4. A hollow plate 82 is installed at the lower end of the L-shaped plate 81. An electric valve tube 84 is inserted and connected to the front of the upper end of the hollow plate 82. The electric valve tube 84 is used to control the inlet and outlet of cold air. A plurality of exhaust holes 83 are provided at the lower end of the hollow plate 82.

[0028] In order to facilitate cold air to blow the surface of the sealing strip, the exhaust hole 83 is located above the lower mold 9.

[0029] Furthermore, the lower end of the rotating plate 103 is in active contact with the upper end of the bottom plate 1 , and the two lower molds 9 are both mounted on the upper end of the rotating plate 103 .

[0030] In order to improve the stability of the upper mold 7 when it moves up and down, the outer surfaces of the front and rear guide columns 2 are both movably sleeved with sliders 3, and the ends of the two sliders 3 close to each other are jointly installed with connecting plates 6, and the ends of the two connecting plates 6 close to each other are respectively fixedly connected to the left and right ends of the upper mold 7.

[0031] An injection tube 11 is inserted and connected to the upper left part of the upper mold 7, and the injection tube 11 is used to guide the injection molding material into the upper mold 7 and the lower mold 9.
