However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0027] See Figures 1-7 A product inclined punching die structure includes an upper die assembly 1 and a lower die assembly 2. The upper die assembly 1 includes a punch component 3 for performing inclined punching on the workpiece die blank. The punch component 3 is movably disposed on the upper die assembly 1. The lower die assembly 2 includes a drive block 4 that cooperates with the punch component 3.

[0028] The workpiece blank is placed on the lower mold assembly 2. During the mold closing process of the upper mold assembly 1 and the lower mold assembly 2, the upper mold assembly 1 moves in the direction of pressing down on the workpiece blank, and the driving block 4 triggers the punch component 3 to move in the direction of acting on the side of the workpiece blank, so that the workpiece blank is pressed down by the upper mold assembly 1 to form an inclined surface, and the punch component 3 punches a hole on the inclined surface of the workpiece blank.

[0029] During the mold closing process, the drive block 4 can trigger the movement of the punch component 3, so that the workpiece blank forms an inclined surface and completes the punching during the mold closing process. After the workpiece is formed, no additional punching is required, which improves the processing accuracy and processing efficiency and effectively shortens the entire processing cycle.

[0030] The punch component 3 includes a slider 5, and a guide inclined surface mating part 6 is provided between the drive block 4 and the slider 5. During the mold opening and closing process, the drive block 4 triggers the slider 5 to move on the upper mold component 1 through the guide inclined surface mating part 6.

[0031] On the one hand, the design of the guide slope mating part 6 enables the drive block 4 to drive the slider 5 to move smoothly and accurately, ensuring the stability and reliability of the punch component 3 in the process of punching on the slope. On the other hand, since the upper mold assembly 1 moves up and down along the lower mold assembly 2, the guide slope mating part 6 can enable the drive block 4 to trigger the slider 5 to make a horizontal linear movement after the slider 5 comes into contact with the drive block 4.

[0032] In this embodiment, the guide slope mating part 6 includes a first slope disposed on the drive block 4 and a second slope disposed on the slider 5.

[0033] The punch component 3 also includes a punch 7, which is inclinedly disposed on the upper mold component 1 and connected to the slider 5.

[0034] The inclined setting of the punch 7 allows it to act directly on the inclined surface of the workpiece blank after forming, so as to realize the inclined surface punching.

[0035] The punch 7 is provided with a connecting block 8, and the slider 5 is provided with a sloping mounting position 9. One end of the connecting block 8 is connected to the punch 7, and the other end of the connecting block 8 is fixed on the sloping mounting position 9 so that the punch 7 is set at an angle.

[0036] The design of the connecting block 8 and the inclined assembly position 9 enables the punch 7 to maintain a stable tilt angle, ensuring the precise positioning and movement of the punch 7 during the punching process, and further improving the processing accuracy.

[0037] In this embodiment, the connecting block 8 is fixedly mounted on the inclined surface assembly position 9 by bolts.

[0038] The upper mold assembly 1 includes a pressure plate 15 that mates with the workpiece mold blank. The pressure plate 15 has a sloping part 16 that presses down on the workpiece mold blank to form a sloping surface on the workpiece mold blank. The pressure plate 15 has an inclined clearance limiting groove 17 corresponding to the connecting block 8. The clearance limiting groove 17 has an inclined through hole 18 that extends to the outside of the sloping part 16. During the mold closing process, the connecting block 8 moves to the clearance limiting groove 17, and the punch 7 acts on the sloping side of the workpiece mold blank towards the inclined through hole 18 to complete the sloping surface punching.

[0039] In this embodiment, the pressure plate 15 is fixed on the upper mold fixing plate, and a number of vertical plates are provided between the upper mold fixing plate and the upper template 12 at intervals.

[0040] The design of the inclined surface 16 of the pressure plate 15 and the clearance limiting groove 17 enables the workpiece blank to accurately form an inclined surface during the mold closing process. At the same time, the clearance limiting groove 17 provides movement space for the punch, ensuring that the punch 7 can smoothly act on the inclined surface and complete the punching, thus improving processing efficiency.

[0041] The upper mold assembly 1 also includes a first limiting block 10 and a second limiting block 11. The slider 5 is disposed between the first limiting block 10 and the second limiting block 11. During the mold opening and closing process, the slider 5 moves between the first limiting block 10 and the second limiting block 11.

[0042] The setting of the first limiting block 10 and the second limiting block 11 restricts the movement range of the slider 5 and prevents the slider from detaching from the upper mold assembly 1 during movement.

[0043] The upper mold assembly 1 includes an upper mold plate 12, a fixed seat 13 and a slider pad 14. The fixed seat 13 is fixed on the bottom of the upper mold plate 12, and the slider pad 14 and the second limiting block 11 are both fixed on the bottom of the fixed seat 13. The first limiting block 10 is fixed on one end face of the slider pad 14.

[0044] The slider pad 14 is provided with a limiting groove 23, and the slider 5 is provided with a limiting protrusion 24. The limiting protrusion 24 is embedded in the limiting groove 23 so that the slider 5 is limited to slide on the slider pad 14.

[0045] The design of the limiting groove 23 and the limiting protrusion 24 allows the slider 5 to slide smoothly on the slider pad 14, preventing the slider 5 from shifting or shaking during movement, and further improving the punching accuracy.

[0046] In this embodiment, limiting protrusions 24 are provided on both sides of the slider 5, and limiting grooves 23 are provided on both inner sides of the slider pad 14. The slider 5 is inserted into the slider pad 14 laterally, and the limiting protrusions 24 are supported on the corresponding limiting grooves 23 to prevent the slider 5 from falling off the slider pad 14 after the mold is opened.

[0047] The lower mold assembly 2 includes a lower mold core plate 19, the lower mold core plate 19 is provided with an insert 20, the insert 20 is provided with a side slope 21, the side slope 21 is provided with a through hole 22. After the mold is closed, the workpiece mold blank forms a slope between the side slope 21 of the upper mold assembly 1 and the lower mold assembly 2, and the punch component 3 punches a hole in the slope of the workpiece mold blank through the through hole 22 of the side slope 21.

[0048] In this embodiment, the lower mold assembly 2 also includes a template that cooperates with the lower mold core plate 19. These are all existing technologies and will not be described in detail here.

[0049] The design of the lower mold core plate 19 and the insert 20 enables the workpiece mold blank to accurately form an inclined surface during the mold closing process. At the same time, the through hole 22 provides a punching channel for the punch 7, ensuring that the punch 7 can smoothly act on the inclined surface and complete the punching, thus improving processing efficiency and quality.

[0050] A guide post assembly is provided between the upper mold assembly 1 and the lower mold assembly 2, and the upper mold assembly 1 and the lower mold assembly 2 perform opening and closing mold actions along the guide post assembly.

[0051] In this embodiment, the guide post assembly includes a guide post and a guide sleeve hole that mates with the guide post. The guide sleeve hole is fixedly disposed on the template of the lower mold assembly 2. The guide post is fixedly disposed on the template of the upper mold assembly 1, and a spring is sleeved on the outer side of the guide post.

[0052] Specifically, the workpiece blank is placed on the lower mold core plate 19 of the lower mold assembly 2. The upper mold assembly 1 closes under the action of the punch. While the pressure plate 15 and the insert 20 cooperate to form a slope on the side of the workpiece blank, the drive block 4 triggers the slider 5. As the upper mold assembly 1 descends, the slider 5 drives the punch 7 to move towards the slope on the side of the workpiece blank along the guide slope mating part 6, so that the punch 7 completes the slope punching action. When the mold opens, the upper mold assembly 1 moves upward, and the slider 5 drives the punch 7 to move along the guide slope mating part 6 in the reset direction. Finally, the workpiece is removed from the lower mold assembly 2.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
