Description

Technical Field

[0001] This utility model relates to the field of automatic stamping equipment technology, and in particular to an automatic stamping equipment for injection mold shells. Background Technology

[0002] Stamping equipment generally includes a punch and a die opposite to the punch, the die having a stamping cavity formed thereon. When stamping is required, the part to be stamped is first positioned on the die, and then the punch moves toward the die and passes through the part to be stamped into the stamping cavity. The part to be stamped is stamped by the punch to form a groove.

[0003] However, traditional stamping equipment often relies on the punch to apply force to the workpiece for hard stamping, which can easily cause bending deformation of the workpiece and stamping machine parts, thus affecting the stamping accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic stamping equipment for injection mold shells, which aims to improve the problem of deformation of stamped parts and stamping machine components caused by traditional punch hard stamping, thus affecting stamping accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic stamping device for injection mold shells, comprising a base plate, a power output structure fixedly installed on the top of the base plate, a push block fixedly connected to one side of the power output structure, a protective structure fixedly connected to one side of the push block, a fixed stamping block fixedly connected to the top of the base plate, a limit rod 1 uniformly fixedly connected to one side of the fixed stamping block, the inner wall of the push block slidably connected to the outer wall of the limit rod 1, a transmission structure rotatably connected to one side of the push block, a connecting block 1 rotatably connected to one side of the transmission structure, a connecting cylinder 2 uniformly fixedly connected to one side of the connecting block 1, the inner wall of the connecting cylinder 2 slidably connected to the outer wall of the limit rod 1, a sliding stamping block fixedly connected to one side of the connecting cylinder 2, the inner wall of the sliding stamping block slidably connected to the outer wall of the limit rod 1, and a stamping mold installed on the opposite side of the sliding stamping block and the fixed stamping block.

[0006] By adopting the above technical solution, the power output structure drives the push block to move forward, causing the transmission structure to change angle, which in turn pushes the sliding stamping block forward. The movement of the protection structure provides a certain buffer resistance for the forward stamping. Connecting block one and connecting rod two complete the extrusion of the stamping die, reducing the damage of hard impact to mechanical parts, reducing stamping noise, and preventing the stamping die from displacement due to hard impact from affecting stamping accuracy. The power output structure drives the push block to move backward, causing the transmission structure to change angle, which drives connecting block one to move backward, pulling the sliding stamping block backward, thus avoiding damage to mechanical parts from sudden pressure drops.

[0007] Preferably, the power output structure includes a servo motor, the bottom of which is fixedly mounted on the top of the base plate.

[0008] Preferably, the output end of the servo motor is fixedly connected to an eccentric wheel, one side of the eccentric wheel is rotatably connected to a connecting rod, and one side of the connecting rod is rotatably connected to a connecting cylinder.

[0009] Preferably, a limiting block is slidably connected to the outer wall of the connecting cylinder, the bottom of the limiting block is fixedly connected to the top of the base plate, and one end of the connecting cylinder is fixedly connected to one side of the pushing block.

[0010] Preferably, the protective structure includes two connecting strips, one side of which is fixedly connected to one side of the push block, and a limiting rod two is fixedly connected to the inner wall of the connecting strip, with one end of the limiting rod two fixedly connected to the inner wall of the push block.

[0011] Preferably, a connecting block two is slidably connected to the outer wall of the limiting rod two, a viscous damper is fixedly installed on one side of the connecting block two, and one side of the viscous damper is fixedly installed on one side of the pushing block.

[0012] Preferably, the transmission structure includes several connecting rods three, one side of which is rotatably connected to one side of the push block, and the other side of which is rotatably connected to a connecting rod two, one side of which is fixedly connected to one side of the connecting block one.

[0013] Preferably, one side of the connecting rod three is rotatably connected to the connecting rod four, and one side of the connecting rod four is rotatably connected to one side of the connecting block two.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the power output structure drives the push block to move forward, causing the transmission structure to change angle, which in turn drives the sliding stamping block to move forward. The movement of the protective structure provides a certain buffer resistance for the forward stamping. The connecting block one and the connecting rod two complete the extrusion of the stamping die, reducing the damage of hard impact to mechanical parts, reducing stamping noise, and preventing the stamping die from displacement due to hard impact from affecting stamping accuracy. The power output structure drives the push block to move backward, causing the transmission structure to change angle, which drives the connecting block one to move backward, pulling the sliding stamping block backward, thus avoiding damage to mechanical parts from sudden pressure drops.

[0016] 2.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-5An embodiment of this utility model provides an automatic stamping device for injection mold shells, including a base plate 1. A power output structure is fixedly installed on the top of the base plate 1. A push block 8 is fixedly connected to one side of the power output structure. A protective structure is fixedly connected to one side of the push block 8. A fixed stamping block 14 is fixedly connected to the top of the base plate 1. A limit rod 19 is uniformly fixedly connected to one side of the fixed stamping block 14. The inner wall of the push block 8 is slidably connected to the outer wall of the limit rod 19. A transmission structure is rotatably connected to one side of the push block 8. A connecting block 11 is rotatably connected to one side of the transmission structure. A connecting cylinder 29 is uniformly fixedly connected to one side of the connecting block 11. The inner wall of the connecting cylinder 29 is slidably connected to the outer wall of the limit rod 19. A sliding stamping block 10 is fixedly connected to one side of the connecting cylinder 29. The inner wall of the sliding stamping block 10 is slidably connected to the outer wall of the limit rod 19. A stamping mold 20 is installed on the opposite side of the sliding stamping block 10 and the fixed stamping block 14.

[0026] Specifically, the power output structure drives the push block 8 to move forward on the limit rod 9, which in turn causes the transmission structure to change angle, driving the connecting block 11 to move forward, and then pushing the connecting cylinder 19 and the sliding stamping block 10 to move forward. The movement of the protective structure provides a certain buffer resistance for the forward stamping. The connecting block 11 and the connecting rod 12 complete the extrusion of the stamping die 20, completing the stamping of the injection mold shell, reducing the damage of hard impact to mechanical parts, reducing stamping noise, and preventing the stamping die 20 from being affected by the displacement due to hard impact, thus improving the stamping accuracy. The power output structure drives the push block 8 to move backward on the limit rod 9, which in turn causes the transmission structure to change angle, driving the connecting block 11 to move backward, and then pulling the connecting cylinder 19 and the sliding stamping block 10 backward. The movement of the transmission structure provides a certain buffer space for the backward stretching, avoiding the sudden drop in pressure that could damage mechanical parts. This improves the problem of deformation of stamped parts and stamping machine parts caused by the hard stamping of traditional punches, which affects stamping accuracy.

[0027] Reference Figure 1 , Figure 2 The power output structure includes a servo motor 2. The bottom of the servo motor 2 is fixedly installed on the top of the base plate 1. An eccentric wheel 3 is fixedly connected to the output end of the servo motor 2. A connecting rod 4 is rotatably connected to one side of the eccentric wheel 3. A connecting cylinder 6 is rotatably connected to one side of the connecting rod 4. A limit block 7 is slidably connected to the outer wall of the connecting cylinder 6. The bottom of the limit block 7 is fixedly connected to the top of the base plate 1. One end of the connecting cylinder 6 is fixedly connected to one side of the push block 8.

[0028] Specifically, the servo motor 2 drives the eccentric wheel 3 to rotate, which in turn drives the connecting rod 4 to rotate, causing the connecting cylinder 6 to move within the limit block 7, and driving the push block 8 to slide back and forth. Power output is completed through a simple mechanical structure, making inspection and maintenance more convenient.

[0029] Reference Figure 3 , Figure 4 The protective structure includes two connecting strips 5. One side of the connecting strip 5 is fixedly connected to one side of the push block 8. A limit rod 16 is fixedly connected to the inner wall of the connecting strip 5. One end of the limit rod 16 is fixedly connected to the inner wall of the push block 8. A connecting block 15 is slidably connected to the outer wall of the limit rod 16. A viscous damper 18 is fixedly installed on one side of the connecting block 15. One side of the viscous damper 18 is fixedly installed on one side of the push block 8.

[0030] Specifically, when the transmission structure moves forward, it drives the connecting block 2 15 to slide forward. The other side of the viscous damper 18 connected to the rear of the connecting block 2 15 is behind the push block 8. The sliding rod of the viscous damper 18 slides through the hole of the push block 8 on the inner wall of the push block 8. The viscous damper 18 provides a certain buffer resistance for forward stamping, reduces the damage of hard impact stamping to mechanical parts, reduces stamping noise, and avoids the displacement of the stamping die 20 caused by hard impact, which affects the stamping accuracy. The connecting strip 5 and the limiting rod 2 16 fixed on the push block 8 limit the sliding of the connecting block 2 15, so that the connecting block 2 15 provides a stable sliding direction for the transmission structure.

[0031] Reference Figure 3 , Figure 4 The transmission structure includes several connecting rods 13. One side of the connecting rod 13 is rotatably connected to one side of the push block 8. The other side of the connecting rod 13 is rotatably connected to the connecting rod 12. One side of the connecting rod 12 is evenly fixedly connected to one side of the connecting block 11. One side of the connecting rod 13 is rotatably connected to the connecting rod 17. One side of the connecting rod 17 is rotatably connected to one side of the connecting block 15.

[0032] Specifically, by pushing block 8, connecting rod 3 13 moves forward, which in turn changes the angle between connecting rod 3 13 and connecting rod 2 12, causing connecting rod 2 12 to move forward and pushing connecting block 1 11 forward. At the same time, the movement of connecting rod 3 13 causes connecting rod 4 17 to move forward, which in turn causes the protective structure to operate. By pushing block 8, connecting rod 3 13 moves backward, which in turn changes the angle between connecting rod 3 13 and connecting rod 2 12, causing connecting rod 2 12 to move backward and pulling connecting block 1 11 backward. The change in the angle between connecting rod 3 13 and connecting rod 2 12 provides a certain buffer space for backward stretching, avoiding damage to mechanical parts from a sudden drop in pressure.

[0033] Working principle: During use, the servo motor 2 drives the eccentric wheel 3 to rotate, which in turn drives the push block 8 to move forward on the limit rod 9. This causes the angle between the connecting rod 13 and the connecting rod 12 to change, pushing the connecting cylinder 19 and the sliding stamping block 10 forward. The connecting rod 13 drives the connecting block 15 to slide forward. The sliding rod of the viscous damper 18 slides through the hole in the push block 8 on the inner wall of the push block 8. The connecting block 11 and the connecting rod 12 complete the extrusion of the stamping die 20, completing the stamping of the injection mold shell. The pressure is driven by the servo motor 2 to rotate the eccentric wheel 3, which in turn drives the push block 8 to move backward on the limit rod 9. This causes the angle between the connecting rod 13 and the connecting rod 12 to change, which in turn pulls the connecting cylinder 19 and the sliding stamping block 10 to move backward. At the same time, the movement of the connecting rod 13 drives the connecting rod 17 to move backward, which in turn drives the connecting block 15 to slide backward. The sliding rod of the viscous damper 18 slides through the hole of the push block 8 on the inner wall of the push block 8. The connecting block 11 and the connecting rod 12 separate from the stamping die 20.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
