Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, and particularly relates to a powder metallurgy mold for a shock absorber valve seat. Background Art

[0002] Shock absorbers can be mainly divided into hydraulic and pneumatic types from the perspective of the damping material. There is also a variable-damping shock absorber. Shock absorbers are mainly used to suppress the oscillation when the spring rebounds after expansion and contraction and the impact from the road surface. During the production of the bottom valve of the shock absorber, a powder metallurgy forming die is required to produce the shock absorber valve seat.

[0003] The utility model patent with the publication number 202120274992.2 discloses a powder metallurgy forming die for a shock absorber bottom valve, including a bottom plate and a top plate. The center of the top surface of the bottom plate is fixedly connected with a lower die. Both sides of the center of the top surface of the lower die are provided with die cavities. Four corners of the top surface of the lower die are fixedly connected with guide rods. By using the cooperation of a limit plate, a support frame, a threaded rod, an anti-slip plate, a positioning sleeve, a push rod, a limit ring plate, a semi-elastic wear-resistant rubber ring, a fixed shaft, a limit groove, a rotating sleeve and a clamping groove, the utility model facilitates the rapid separation between the upper and lower dies, so that the powder metallurgy forming die has a higher production efficiency for the shock absorber bottom valve, and solves the problem that in the process of producing the shock absorber bottom valve by the powder metallurgy forming die, a large amount of time is consumed during the separation of the upper and lower dies because they cannot be separated quickly, resulting in a low production efficiency of the powder metallurgy forming die for producing the shock absorber bottom valve.

[0004] However, there are still some drawbacks in the actual use of the above device. More obviously, after the stamping work of the mold is completed, the produced valve seat placed in the die cavity is not convenient to take out, and a large amount of time is required to take it out of the die cavity, resulting in low production efficiency. During the process of removing the product in the die cavity, the mold cannot participate in the production process, further reducing the production efficiency.

[0005] Therefore, it is necessary to invent a powder metallurgy mold for a shock absorber valve seat to solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a powder metallurgy mold for a shock absorber valve seat. By arranging an L-shaped limit plate at one end of the lower mold, the L-shaped limit plate can be limited inside the bearing plate through a pin, so as to quickly limit and fix the L-shaped limit plate. At the same time, a driving component is arranged at the bottom end of the moving plate, which can effectively move the moving plate and the lower mold. After the stamping work is completed, the lower mold can be quickly removed to take out the product inside the mold cavity, and at the same time, a new lower mold can be quickly installed to participate in the production work, effectively improving the production efficiency, so as to solve the problem that after the mold completes the stamping work, the produced valve seat placed in the mold cavity is not convenient to take out, and it takes a lot of time to take it out of the mold cavity, resulting in low production efficiency. During the process of taking out the product in the mold cavity, the mold cannot participate in the production process, further reducing the production efficiency as mentioned in the above background technology.

The output end of the hydraulic cylinder 2 is fixedly connected to an upper mold 3. A lower mold 4 is arranged at the bottom end of the upper mold 3;

[0030] A movable plate 6 is slidably connected to the top end of the operating table 1. A bearing plate 61 is fixedly connected to one side of the movable plate 6. A limit groove 611 and a second jack 612 are arranged inside the bearing plate 61;

[0031] An L-shaped limit plate 41 is fixedly connected to one side of the lower mold 4. The L-shaped limit plate 41 is arranged inside the second jack 612. A first jack 411 is arranged at the top end of the L-shaped limit plate 41. The first jack 411 and the limit groove 611 are arranged corresponding to each other. A pin 5 is arranged inside the first jack 411 and the limit groove 611. By arranging the L-shaped limit plate 41, the L-shaped limit plate 41 can be inserted into the second jack 612 for limiting. At the same time, the first jack 411 and the limit groove 611 are in corresponding positions, so that the pin 5 can be inserted into the first jack 411 and the limit groove 611 to further limit the position of the L-shaped limit plate 41. The movement of the movable plate 6 drives the L-shaped limit plate 41 and the lower mold 4 to move. After the stamping work is completed, the lower mold 4 can be quickly removed to take out the product inside the mold cavity 43, and at the same time, a new lower mold 4 can be quickly installed to participate in the production work, effectively improving the production efficiency.

[0032] Slide rods 12 are symmetrically and fixedly connected to the top end of the operating table 1. A mold cavity 43 is arranged at the top end of the lower mold 4. Through grooves 42 are arranged on both sides of the bottom end of the lower mold 4. The through grooves 42 are slidably connected to the outer sides of the slide rods 12. By arranging the slide rods 12, the through grooves 42 are arranged corresponding to the slide rods 12 at the bottom end of the lower mold 4, so that the through grooves 42 slide on the outer sides of the slide rods 12, increasing the stability of the movement of the lower mold 4.

[0033] A chute 13 is provided inside the operating table 1. On both symmetric sides at the bottom of the operating table 1, a first mounting block 14 and a second mounting block 15 are respectively and fixedly connected.

A connecting block 62 is fixedly connected to the top of the driving block 63. A moving plate 6 is fixedly connected to the top of the connecting block 62. The connecting block 62 is slidably connected to the inside of the chute 13. By providing the driving block 63, the driving block 63 is threadedly connected to the lead screw 71. When the lead screw 71 rotates, it can effectively drive the driving block 63 to move. The connecting block 62 and the moving plate 6 are fixedly connected to the top of the driving block 63, so that the moving plate 6 can be effectively driven to move.

[0034] During specific use, start the driving motor 7 to drive the lead screw 71 to rotate, thereby driving the driving block 63 to move, and finally driving the L-shaped limiting plate 41, i.e., the lower die 4, arranged at the top of the bearing plate 61 to move. Move it to the inside of the support frame 11, start the hydraulic cylinder 2 to drive the upper die 3 to move downward to complete the die closing with the lower die 4, and perform the stamping work;

[0035] After the stamping is completed, start the driving motor 7 to drive the lower die 4 to move to the outside of the support frame 11, remove the bolt 5, and pull out the L-shaped limiting plate 41 from the inside of the second jack 612, which is convenient for removing the lower die 4, completing the mold removal work, and replacing it with a new lower die 4 to perform the stamping work again, effectively improving the stamping efficiency.
