Technical Field
[0001] This utility model belongs to the field of stamping forming technology, specifically a stamping forming mold for an oil pump holder. Background Technology
[0002] With the development of science and technology, 70% of the parts in the current automobile and motorcycle parts production are produced by stamping dies. Some sheet metal parts are usually obtained by cold stamping. Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the required parts. In the existing oil pump seat stamping die, if the gap between the elastic stripper plate and the punch is too large, the strip material is prone to shifting during unloading. If ordinary cylindrical springs are used, their elasticity will decrease after long-term use, resulting in insufficient unloading force. Scrap or parts may get stuck in the die, causing equipment overload and shutdown, or even damage to the punch. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1 to 4The present invention includes a support 1, an upper die base 2 fixedly connected to the inner wall of the support 1, a stamping push rod 24 provided at the top of the upper die base 2, a rack frame 17 fixedly connected to the bottom of the upper die base 2, a pad 6 fixedly connected to the bottom of the pad 6, an upper clamping plate 7 fixedly connected to the bottom of the pad 6, an upper template 8 fixedly connected to the inner wall of the upper clamping plate 7, a stamping assembly provided on the inner wall of the upper die base 2, and a lower die base 3 fixedly connected to the inner wall of the support 1. The inner wall of the upper die set 8 is rotatably connected to two rotating rods 16. The outer walls of both rotating rods 16 are fixedly connected to synchronous pulleys 19. The teeth of the synchronous pulleys 19 are meshed with a synchronous belt 20. The teeth of the rack frame 17 are meshed with a gear 18. One of the rotating rods 16 is fixedly connected to a gear 21. The teeth of the gear 21 are meshed with a rack frame 22. The outer wall of the rack frame 22 is slidably connected to a top block frame 23. The inner wall of the upper die set 8 is equipped with a cooling assembly. The stamping assembly includes pressure rods 10. Multiple pressure rods 10 are slidably connected to the inner wall of the upper die set 2. The bottom ends of the multiple pressure rods 10 are fixedly connected to pressure plates 9. The outer walls of the pressure rods 10 are equipped with springs 11. The inner wall of the upper die set 2 is fixedly connected to multiple guide sleeves 4. The inner walls of the guide sleeves 4 are slidably connected to guide pillars 5. The top of one pad 6 is fixedly connected to a lower clamping plate 15. The top of the lower clamping plate 15 is fixedly connected to a lower die set 13. The top block frame 2... 3. The lower die base 3, the pad 6 and the cooling water channel 2 14 are slidably connected to the inner wall. The rack frame 2 22 is slidably connected to the inner wall of the lower die base 3. Multiple springs 11 are set at the bottom end of the upper die base 2. The pressure plate 9 is slidably connected to the outer wall of the upper template 8. Multiple guide pillars 5 are fixedly connected to the top end of the lower die base 3. The stamping push rod 24 is installed at the top end of the bracket 1. The rack frame 1 17 is slidably connected to the inner wall of the lower die base 3. The gear 1 18 is fixedly connected to the outer wall of the rotating rod 16.
[0023] In use, the upper die holder 2 and the lower die holder 3 are fixedly connected to the inner wall of the support 1. The stamping push rod 24 is installed between the top of the support 1 and the top of the upper die holder 2. Four guide sleeves 4 are fixedly connected to the inner wall of the upper die holder 2. Four guide pillars 5 are fixedly connected to the top of the lower die holder 3 and slide on the inner wall of the guide sleeves 4. The spring 11 and the outer wall of the pressure rod 10 are connected between the upper die holder 2 and the pressure plate 9. The rack frame 17 is fixedly connected to the bottom of the upper die holder 2, and its tooth ends mesh with the gear 18. The two synchronous pulleys 19 are fixedly connected to the outer wall of the rotating rod 16 and, through the lower die holder 3 and the synchronous belt 20, enable the gear 18 and the gear 21 to rotate together. The tooth ends of the rack frame 22 mesh with the gear 21 and slide on the top block frame. The inner wall of the mold base 23 allows the top block 23 to slide on the inner wall of the lower mold base 3, the pad 6, and the lower clamping plate 15, allowing the raw material to be placed on the top of the lower mold plate 13. The upper mold base 2 then moves the stamping assembly downwards via the stamping push rod 24, causing the rack frame 17 to move downwards via the rotating rod 16, gear 18, synchronous wheel 19, synchronous belt 20, and gear 21. The pressure plate 9 fixes the raw material, and the upper mold plate 8 stamps the raw material. After stamping, the upper mold base 2 moves the stamping assembly upwards via the stamping push rod 24, causing the rack frame 17 to indirectly move the rack frame 22 upwards. The rack frame 22 then pushes the stamped part upwards through the top block 23 to detach it from the lower mold plate 13, achieving the effect of convenient demolding of the stamped part.
[0024] The cooling assembly includes a cooling water channel 12, which is disposed on the inner wall of the upper template 8 and installed on the inner wall of the upper clamping plate 7. The inlet of the cooling water channel 12 is connected to a water tap. A cooling water channel 2 14 is installed on the inner wall of the lower template 13, and the inlet of the cooling water channel 2 14 is connected to a water tap.
[0025] In use, cooling water channel 12 is installed on the inner wall of the upper clamping plate 7 and the upper template 8, and cooling water channel 2 14 is installed on the inner wall of the lower template 13. When the upper template 8 and the lower template 13 generate heat through repeated friction of the raw materials, the local temperature rises, which reduces the hardness of the materials of the upper template 8 and the lower template 13. When the cooling water channel 12 and the cooling water channel 2 14 are connected to the water source, the upper template 8 and the lower template 13 are cooled down respectively, achieving the effect of heat dissipation of the upper template 8 and the lower template 13.
[0026] The raw material is placed on the top outer wall of the lower template 13, and then the stamping push rod 24 is activated to push the upper mold base 2 and the stamping assembly downward. The pressure plate 9 fixes the raw material through the spring 11 and the pressure rod 10, and the upper template 8 stamps the raw material through the lower template 13. The rack frame 17 and the rack frame 22 are driven by the gear 18, the synchronous wheel 19, the rotating rod 16, the synchronous belt 20 and the gear 21, so that the rack frame 17 and the rack frame 22 move together. When the upper mold base 2 moves downward, the rack frame 22 moves downward. When the upper mold base 2 moves upward, the rack frame 22 drives the top block frame 23 and the stamping part to move upward, so that the stamping part is separated from the lower template 13, achieving the effect of convenient demolding of the stamping part.
[0027] After multiple stamping operations, the upper die plate 8 and the lower die plate 13 are heated. The water flow through the cooling water channel 12 and the cooling water channel 2 14 cools the upper die plate 8 and the lower die plate 13, thus achieving the effect of heat dissipation for the upper die plate 8 and the lower die plate 13.
