Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to an injection mold for an automobile handbrake base. Background Art

[0002] In automobile processing, injection molds are crucial in the processing of auto parts. They can accurately manufacture complex-shaped auto parts. In the face of a series of plastic accessories such as the car handbrake base, injection molds can better perform their injection molding, meeting the high standards of automobile manufacturing for quality and performance, and are an indispensable part of auto parts manufacturing.

[0003] When the ejector pin of an existing injection mold pushes the product out of the mold, the friction between the mold, the surface, and the product often prevents the product from being completely removed in one go. The ejector pin needs to push the product back and forth multiple times, resulting in low material removal efficiency after injection molding. Therefore, an injection mold for an automobile handbrake base is proposed. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides an injection mold for an automobile handbrake base, which provides a set of injection molds that can be used for the production of automobile handbrake bases and can be used for self-feeding. By combining the physical contact pushing and pneumatic blowing discharge methods, the handbrake base product can quickly leave the mold cavity and be discharged outside the mold, which can effectively improve the efficiency of the automobile handbrake base injection molding process.

[0005] The technical solution adopted by the utility model to solve its technical problems is an injection mold for a car handbrake base, including an injection mold, a discharge part and an air pump. The injection mold includes a female mold and a male mold. The male mold is located on one side of the female mold. The adjacent sides of the female mold and the male mold are each provided with a mold cavity. The surface area of ​​the mold cavity of the female mold is larger than the surface area of ​​the mold cavity of the male mold, and the mold cavities of the female mold and the male mold are matched to form an injection cavity for the car handbrake base. The discharge part includes a mounting seat.

[0006] By adopting the above technical solution, a set of injection molds with independent unloading capabilities is provided for the production of automobile handbrake bases through an assembly consisting of an injection mold, a discharge part, and an air pump. By combining the unloading methods of physical contact pushing and pneumatic blowing discharge, the handbrake base product can quickly leave the mold cavity and be discharged outside the mold, which can effectively improve the efficiency of the injection molding process of the automobile handbrake base.

[0007] Specifically, the mounting seat is installed in the mother mold, and the mounting seat is equipped with electric push rods corresponding in number to the upper mold cavity of the mother mold.

[0008] Specifically, a top block is installed at the output end of the electric push rod, and one end of the top block away from the electric push rod passes through the mold cavity of the mother mold and is flush with the inner surface of the mold cavity of the mother mold.

[0009] By adopting the above technical solution, through the cooperation between the electric push rod and the ejector block, the electric push rod can push the ejector block, so that the ejector block enters the mold cavity to eject the injection molded product.

[0010] Specifically, exhaust ports are provided at equal distances on the outer periphery of the top block away from one end of the electric push rod, the inner cavity of the top block is a hollow structure, and an air pipe communicating with the exhaust port is connected to one side of the top block.

[0011] By adopting the above technical solution, through the exhaust ports provided on the periphery of the top block, after the end of the top block is pushed into the mold cavity, the exhaust ports on the periphery of the top block can blow air between the inner wall of the mold cavity and the injection-molded product. Based on the air pressurization, the product is quickly separated from the mold cavity, and at the same time, auxiliary cooling of the injection-molded product is achieved, thereby greatly shortening the operation time of unloading the material outside the mold after the automobile handbrake base is re-injected.

[0012] Specifically, a gas distribution box is provided on one side of the mounting base, and the exhaust end of the gas distribution box is connected to the air inlet end of the air pipe.

[0013] Specifically, the air pump is installed on one side of the mother mold, and the exhaust end of the air pump is connected to the air inlet end of the air separation box.

[0014] By adopting the above technical solution, high-pressure air is provided to the exhaust port of the top block through the air pump.

[0015] The beneficial effects of the utility model are as follows: through the assembly consisting of the injection mold, the discharge part and the air pump, a set of injection molds with independent unloading is provided for the production of the base of the automobile handbrake. By combining the unloading methods of physical contact pushing and pneumatic blowing and discharging, the handbrake base product can quickly leave the mold cavity and be discharged outside the mold, which can effectively improve the efficiency of the injection molding process of the automobile handbrake base, and solve the problem that the ejector of the existing injection mold cannot completely remove the product at one time due to the friction between the mold, the surface and the product during the process of pushing the product out of the mold, and the ejector needs to push the product back and forth multiple times, resulting in low unloading efficiency after the product is injected.

The injection mold 1 includes a female mold 11 and a male mold 12. The male mold 12 is located on one side of the female mold 11. A mold cavity 13 is provided on the adjacent side of the female mold 11 and the male mold 12. The surface area of ​​the mold cavity 13 of the female mold 11 is larger than the surface area of ​​the mold cavity 13 of the male mold 12, and the mold cavity 13 of the female mold 11 and the male mold 12 are matched to form an injection cavity for the car handbrake base. The discharge part includes a mounting seat 2.

[0024] When in use, the injection mold 1, the discharge part and the air pump 3 provide a set of injection molds capable of autonomous unloading for the production of the automobile handbrake base. By combining the unloading methods of physical contact pushing and pneumatic blowing discharge, the handbrake base product can quickly leave the mold cavity and be discharged outside the mold, which can effectively improve the efficiency of the injection molding process of the automobile handbrake base.

[0025] The present invention further comprises that the mounting seat 2 is mounted in the mother mold 11 , and the mounting seat 2 is provided with electric push rods 21 corresponding in number to the mold cavity 13 on the mother mold 11 .

[0026] The utility model also includes that a top block 22 is installed at the output end of the electric push rod 21 , and the end of the top block 22 away from the electric push rod 21 passes through the mold cavity 13 of the mother mold 11 and is flush with the inner surface of the mold cavity 13 of the mother mold 11 .

[0027] During use, based on the cooperation between the electric push rod 21 and the ejector block 22 , the electric push rod 21 can push the ejector block 22 so that the ejector block 22 enters the mold cavity to eject the product after injection molding.

[0028] The utility model also includes that the outer periphery of the top block 22 away from one end of the electric push rod 21 is equidistantly provided with an exhaust port 221 , the inner cavity of the top block 22 is a hollow structure, and one side of the top block 22 is connected to an air pipe 222 communicating with the exhaust port 221 .

[0029] During use, by utilizing the exhaust port 221 provided on the periphery of the top block 22, after the end of the top block 22 is pushed into the mold cavity, the exhaust port 221 on the periphery of the top block 22 can blow air between the inner wall of the mold cavity and the injection molded product. Based on the air pressurization, the product is quickly separated from the mold cavity, and at the same time, auxiliary cooling of the injection molded product is achieved, thereby greatly shortening the operation time of unloading the material outside the mold after the automobile handbrake base is re-injected.
