Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and relates to an in-mold film lamination injection mold for a commercial vehicle air outlet grille assembly. Background Art

[0002] Injection mold processing is a process. According to the shape of a product, a cavity matching the shape of the product is provided in the mold. By injecting a plastic material into the cavity of the mold, the product can be taken out after cooling and shaping. Injection processing has the advantages of low cost and short cycle, and is widely applied especially to air outlet grilles of automobile accessories.

[0003] In the prior art, for example, the one with patent publication number CN218227667U discloses a molding mold for an automobile air conditioner outlet grille. The outer peripheral surfaces of a left mold and a right mold are both attached to the inner wall of a sliding chute inside a sliding rail, a limiting step is provided on the side of the right mold facing the left mold, the limiting step is in the shape of a "square" (Chinese character hui), a groove is formed on the side of the left mold facing the right mold, and the shape of the groove matches that of the limiting step; in the molding mold for the automobile air conditioner outlet grille, by arranging a limiting plate, a screw rod and the limiting step, when the screw rod rotates, the limiting plate moves downwards, the limiting plate extrudes the limiting step, so that the limiting step presses against the left mold, the pressure between the left mold and the right mold is increased, higher pressure is required for raw material leakage, so the mold is more suitable for high-speed and high-pressure injection molding, the limiting step increases the leakage path of the product between the left mold and the right mold, thereby prolonging the time required for product leakage, has stronger air tightness, can effectively improve the sealing performance of the product, and makes the whole device suitable for high-pressure and high-speed injection molding production.

[0004] However, in the above disclosed solution, since the length of the air outlet grille is relatively long, certain deflection is prone to occur at both ends of the grille during the mold opening and separation process, and combined with uneven force distribution during angled lifter movement, cracks exist at both ends of the demolded air outlet grille. For this reason, we design an in-mold film lamination injection mold for a commercial vehicle air outlet grille assembly. Summary of the Invention

[0005] The object of the utility model is to provide an in-mold film lamination injection mold for a commercial vehicle air outlet grille assembly, so as to solve the problem raised in the above background art.

[0006] The objective of this utility model can be achieved through the following technical solution: an in-mold coating injection mold for a commercial vehicle air vent grille assembly, comprising an upper injection mold body and a lower injection mold base connected to the upper injection mold body, wherein the air vent grille assembly is injection molded within the upper injection mold body and the lower injection mold base, a mold base is installed at the bottom end of the lower injection mold base, an upper mold sprue plate is installed at the top of the upper injection mold body, a sprue panel is installed at the top of the upper mold sprue plate, a hot sprue position is installed at the center of the top of the sprue panel, a mold opening base plate is installed at the top of the base plate of the mold base, vertical ejector pins are installed at the four corners of the top of the mold opening base plate, and a mold opening pad is installed at the top of each vertical ejector pin, the four mold opening pads being located at the four corners of the air vent grille assembly.

[0007] In the aforementioned in-mold coating injection mold for commercial vehicle air vent grille assembly, an integrally formed air vent grille assembly module is provided at the top of the lower injection mold base. A grille assembly mold core is provided at the top of the air vent grille assembly module. An integrally formed grille assembly forming cavity is opened at the bottom of the upper injection mold body. The grille assembly forming cavity corresponds to the air vent grille assembly module and forms the air vent grille assembly component. This design aims to achieve better integral injection molding of the air vent grille, ensuring that the air vent grille has good strength.

[0008] In the aforementioned in-mold coating injection mold for commercial vehicle air vent grille assembly, guide post holes are provided at the four corners of the top of the lower injection mold base. Each guide post hole contains a guide post to connect to the guide hole of the upper injection mold body. The purpose of this design is to ensure good mold closing accuracy after the upper injection mold body and the lower injection mold base are closed, and to provide good guiding effect during the mold opening process.

[0009] In the aforementioned in-mold coating injection mold for the commercial vehicle air vent grille assembly, the top of the mold opening base plate is further provided with multiple core inserts, each of which passes through the air vent grille assembly module and corresponds to the air vent grille assembly component. This arrangement facilitates better injection molding of the air vent grille assembly and also makes mold opening easier.

[0010] In the aforementioned in-mold coating injection mold for the commercial vehicle air vent grille assembly, multiple inclined ejector connectors are installed at the top of the mold opening base plate. An inclined ejector rod seat is installed on the inner side of each inclined ejector connector, and an inclined ejector rod body is installed at one end of each inclined ejector rod body. A forming inclined ejector head is provided at one end of each inclined ejector rod body, and each forming inclined ejector head contacts the undercut portion of the air vent grille assembly. This arrangement facilitates better ejection of the formed air vent grille assembly from the mold cavity.

[0011] Compared with existing technologies, the advantages of this utility model of in-mold coating injection mold for commercial vehicle air vent grille assembly are as follows: Vertical ejector pins are installed at the four corners of the top of the mold opening base plate, and each vertical ejector pin has an opening pad at its top. These four opening pads are located at the four corners of the air vent grille assembly. This ensures that during the mold opening and separation process, the turbulence caused by the length of the air vent grille assembly is reduced, facilitating better separation of the air vent grille assembly from the mold cavity and preventing cracks at both ends of the ejected air vent grille.
