[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 4 The utility model provides an embodiment: a mold for forming a double-sided chamfered fork part, including a lower mold base 1, the outer wall of the lower mold base 1 is fixedly connected to a positioning rod 2, the outer wall of the positioning rod 2 is slidably connected to a middle plate 3, the outer wall of the positioning rod 2 is slidably connected to an upper mold base 4, the interior of the upper mold base 4 is fixedly connected to an upper pad 5, the outer wall of the upper mold base 4 is fixedly connected to a top seat 6, a stamping assembly is arranged inside the top seat 6, and the stamping assembly is used to stamp and form the device, the interior of the upper mold base 4 is fixedly connected to a mounting plate 8, the interior of the lower mold base 1 is fixedly connected to a fixing plate 9, the outer wall of the fixing plate 9 is fixedly connected to a slide seat 10, and the interior of the slide seat 10 is slidably connected to A slide rod 11 is connected, one end of the slide rod 11 is fixedly connected to a plug plate 12, the other end of the slide rod 11 is fixedly connected to a fixing ring 13, the outer wall of the plug plate 12 is fixedly connected to a limiting block 14, the outer wall of the fixing ring 13 is fixedly connected to a slide button 16, and the outer wall of the slide rod 11 is sleeved with a limiting spring 15; the stamping assembly includes a main punch 7, the outer wall of the main punch 7 is fixedly connected to the inside of the top seat 6; the outer wall of the slide seat 10 is slidably connected to the inside of the mounting plate 8, the outer wall of the limiting block 14 is slidably connected to the inside of the slide seat 10, one end of the limiting spring 15 is fixedly connected to the inside of the slide seat 10, and the other end of the limiting spring 15 is fixedly connected to the outer wall of the fixing ring 13;

[0026] Specifically, when it is necessary to quickly and firmly fix the lower die base 1 and the upper die base 4, the upper die base 4 is compressed downward along the guidance of the positioning rod 2, which enables the slide 10 to slide smoothly into the interior of the mounting plate 8. At the same time, the mounting plate 8 pushes the plug plate 12 to slide inside the slide 10, and the slide rod 11 pushes the fixing ring 13, so that the fixing ring 13 can compress the limit spring 15, and the limit block 14 moves inside the slide 10 to limit the position of the plug plate 12. When the plug plate 12 completely slides into the interior of the mounting plate 8, the limit spring 15 will rebound and push the fixing ring 13, so that the fixing ring 13 resets the plug plate 12, which enables the plug plate 12 to be firmly stuck in the interior of the mounting plate 8, thereby quickly achieving firm fixation of the lower die base 1 and the upper die base 4. The whole process not only ensures the stability of the mold during processing, but also ensures the smooth progress of the processing operation, effectively simplifies the mold assembly process, and improves work efficiency and accuracy.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The outer wall of the lower die base 1 is fixedly connected with a lower pad 17, and the outer wall of the lower pad 17 is slidably connected with a concave die plate 18; the inside of the concave die plate 18 is fixedly connected with a chamfering insert 28, and the outer wall of the chamfering insert 28 is slidably connected with a material strip 27; the inside of the concave die plate 18 is fixedly connected with a ejector 19, and the inside of the ejector seat 6 is fixedly connected with a waste ejector rod 20; the outer wall of the upper die base 4 is fixedly connected with a water pump 21, the output end of the water pump 21 is fixedly connected with a water pipe 22, one end of the water pipe 22 is fixedly connected with a cooling pipe 23, and one end of the cooling pipe 23 is fixedly connected with a water storage barrel 24; the inside of the water storage barrel 24 is fixedly connected with a connecting pipe 25, one end of the connecting pipe 25 is fixedly connected to the inside of the water pump 21, and the inside of the upper die base 4 is fixedly connected with a cooling fan 26;

[0028] Specifically, when it is necessary to demold the device and waste quickly, the water pump 21 cooperates with the connecting pipe 25 to draw water from the water storage barrel 24 and transport it to the cooling pipe 23 through the water pipe 22. The cooling pipe 23 surrounds the interior of the upper mold base 4 to quickly cool and shape the molded device to ensure the accuracy of the device size and shape. At the same time, the ejector 19 and the waste ejector rod 20 cooperate to eject the molded device and the waste at the same time. In this process, the ejector 19 uses the pushing force to make the device smoothly ejected from the mold, and the waste ejector rod 20 pushes the waste out of the mold. This not only improves the convenience of the mold, but also significantly speeds up the production efficiency of the mold, ensuring that the device can be demolded quickly and accurately after molding, and through the effective cooling of the cooling pipe 23, the quality and dimensional stability of the finished product are guaranteed.

[0029] Working principle: When the lower die base 1 and the upper die base 4 need to be quickly assembled, the upper die base 4 is compressed downward along the guidance of the positioning rod 2, so that the slide 10 can slide into the interior of the mounting plate 8, and the mounting plate 8 will push the plug plate 12 to slide inside the slide 10, and then the slide rod 11 pushes the fixing ring 13 to compress the limit spring 15, wherein the limit block 14 slides inside the slide 10 to limit the position of the plug plate 12, when the plug plate 12 completely slides into the interior of the mounting plate 8, the limit spring 15 will rebound and push the fixing ring 13 to reset the plug plate 12, so that the plug plate 12 can be stuck in the interior of the mounting plate 8, thereby achieving the effect of quickly and firmly fixing the lower die base 1 and the upper die base 4, improving the stability of the mold and ensuring the smooth processing process. The upper pad 5 and the concave mold plate 18 are both embedded with chamfer inserts 28, so that the mold can be chamfered on both sides, thereby reducing the machining process, avoiding the secondary clamping of parts, stabilizing product quality, shortening the production cycle, and reducing production costs. When it is necessary to quickly demold the device and waste, the water flow in the water storage barrel 24 is extracted by the water pump 21 in cooperation with the connecting pipe 25, and then transported to the cooling pipe 23 by the water pipe 22, so that the cooling pipe 23 surrounds the inside of the upper mold base 4 to cool and shape the molded device, and then the ejector 19 and the waste ejector rod 20 cooperate to eject the device and the waste at the same time, thereby achieving the effect of quickly cooling and demolding the molded device, improving the convenience of the mold, and accelerating the production efficiency of the mold.
