Description

Technical Field

[0001] The utility model relates to the technical field of forging dies or installation thereof, in particular to a forming die for an automobile bracket. Background Art

[0002] After the automobile bracket production process is completed, in order to speed up the separation of the automobile bracket from the mold, it is often necessary to add mold auxiliary components to accelerate demolding. The Chinese utility model patent, authorization announcement number "CN218080212U", discloses a special molding mold for an automobile shock absorber bracket, including a base, a support rod is arranged on the surface of the base, a top seat is fixed on the surface of the support rod, a hydraulic cylinder is fixed on the surface of the top seat, a pressure plate is fixed on the lower end of the hydraulic cylinder, a lower mold seat is fixed on the surface of the base, an upper mold seat is fixed on the lower surface of the pressure plate, mold cavities are provided on the surfaces of the lower mold seat and the upper mold seat, a convex hole and a transverse channel are provided on the inner side surface of the lower mold seat, a convex pin is slidably connected in the convex hole, a convex nozzle is arranged on the outer end of the transverse channel, and an air guide tube is fixedly connected to the outer end of the convex nozzle.

[0003] The above technical solution adopts a pneumatic ejection component, which can lift the convex pin through air guide, which can facilitate the ejection of the bracket workpiece after forging and pressing, and facilitate the removal of the material. The automobile bracket is usually ejected with a large force. Since the force between the automobile bracket and its mold is large at the beginning, when it is ejected at one end, the force between the automobile bracket and the mold will be reduced by an order of magnitude, that is, the automobile bracket is very easy to detach from the mold. Since its force is only the ejection force, the automobile bracket cannot be controlled to be zero at the instant of ejection from the mold, that is, when the automobile bracket is ejected, it has an initial velocity. If the operator does not take it out in time, the bracket will move downward. Since the convex pin falls by its own gravity, its falling rate is limited, and there is a possibility that the automobile bracket falls and collides with the naturally falling convex pin. At the same time, the automobile bracket that has just been produced has strong plasticity, and it is easy for the automobile bracket to collide with the convex pin and be damaged. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a forming die for an automobile bracket, which can solve the problem that the automobile bracket just produced has strong plasticity and is prone to collision damage.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a forming die for an automobile bracket, comprising a hydraulic press, a lower die being installed on the upper surface of the hydraulic press;

[0006] The ejection assembly is arranged inside the hydraulic press, and the ejection assembly includes three sliding columns, three sealing rings, three baffles, three springs, three sliding columns, three annular sleeves, three pistons, three piston rods, three connecting plates, an air pump, three first grooves, three second grooves and three sliding grooves. The three second grooves are all arranged on the hydraulic press, the three sliding grooves are all arranged on the hydraulic press, the three sliding columns slide inside the corresponding sliding grooves respectively, the three sealing rings are respectively sleeved on the corresponding sliding columns, and the three first grooves are all arranged on the lower mold.

[0007] Preferably, the three connecting plates are respectively sleeved on corresponding sliding columns, and the three piston rods are respectively adhered to the corresponding sliding columns.

[0008] Preferably, the three sliding columns are fixedly adhered to the inside of the hydraulic press, and the three baffles are respectively adhered to the corresponding sliding columns.

[0009] Preferably, one ends of the three springs are respectively adhered to the corresponding blocking sheets, and the other ends of the three springs are respectively adhered to the corresponding connecting plates, and the three connecting plates slide on the corresponding sliding columns respectively.

[0010] Preferably, an air pump is installed inside the hydraulic press, and the output end of the air pump is connected to three annular sleeves.

[0011] Preferably, a mold groove is provided on the surface of the lower mold, and an upper mold is installed on the hydraulic press.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The molding die for the automobile bracket is provided with a spring in the ejection assembly. The spring can be stretched and stored in energy during the ascending process of the sliding column. After the automobile bracket is ejected, the spring releases energy to pull the sliding column back to the inside of the second groove quickly. In this way, the automobile bracket will not collide with the sliding column and bend during the falling process, but will fall back into the inside of the mold groove. The overall force of the automobile bracket is evenly applied, and the excessive force at a certain point will not cause the automobile bracket to bend, thereby ensuring the integrity of the automobile bracket after being ejected.

[0014] (2) The automobile bracket forming mold is provided with three sliding columns to eject the automobile bracket, so that the force of pushing the automobile bracket is more uniform, thereby avoiding excessive concentration of force at a certain part of the automobile bracket and causing bending. The three sliding columns are used for ejection, which can avoid the phenomenon of damage to the automobile bracket due to concentrated force, thereby ensuring the integrity of the ejected automobile bracket.

[0027] See also Figure 1-6 , the utility model provides a technical solution: a forming die for an automobile bracket, comprising a hydraulic press 3, a lower die 2 is installed on the upper surface of the hydraulic press 3;

[0028] The ejection assembly is arranged inside the hydraulic press 3, and the ejection assembly includes three sliding columns 5, three sealing rings 6, three baffles 7, three springs 8, three sliding columns 9, three annular sleeves 10, three pistons 11, three piston rods 12, three connecting plates 13, an air pump 14, three first grooves 15, three second grooves 16 and three sliding grooves 17.

[0034] A mold groove 4 is formed on the surface of the lower mold 2 , and an upper mold 1 is mounted on the hydraulic press 3 .

[0035] When it is necessary to form an automobile bracket, first, the hydraulic press 3 is started to drive the upper mold 1 to move downward until it contacts the lower mold 2, and then the raw material is injected into the mold groove 4, and then cooled to form.

[0036] Secondly, start the hydraulic press 3 to drive the upper mold 1 to separate from the upper surface of the lower mold 2, and then start the air pump 14 to inflate the three annular sleeves 10. The inflation of the three annular sleeves 10 drives the corresponding pistons 11 to move upward respectively, and the upward movement of the three pistons 11 drives the corresponding piston rods 12 to move upward.

Then, after the automobile bracket is ejected, the spring 8 releases energy to pull the sliding column 5 back to the inside of the second groove 16 quickly, so that the automobile bracket will not collide with the sliding column 5 and bend during the falling process, but will fall back into the mold groove 4, so that the overall force of the automobile bracket is evenly applied, and there will be no excessive force at a certain point, which will cause the automobile bracket to bend, thereby ensuring the integrity of the automobile bracket after being ejected.

[0039] By arranging three sliding columns 5 to eject the automobile bracket, the force of pushing the automobile bracket is more uniform, thereby avoiding excessive concentration of force at a certain part of the automobile bracket and bending. The three sliding columns 5 can avoid the phenomenon of damage to the automobile bracket due to concentrated force, thereby ensuring the integrity of the ejected automobile bracket.
