[0030] 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.

[0031] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a stamping die for furniture hardware, including a shell 1, a top plate 2 is fixedly connected to the top of the shell 1, a hydraulic rod 3 is fixedly connected to the bottom of the top plate 2, an upper mold 4 is fixedly connected to the output end of the hydraulic rod 3, a lower mold 5 is fixedly connected to the top of the shell 1, a lower mold 2 7 is fixedly connected to the inside of the shell 1, a limiting column 8 is fixedly connected to the inside of the shell 1, a cross bar 9 is slidably connected to the outer wall of the limiting column 8, a top column 11 is fixedly connected to the top of the cross bar 9, the outer wall of the top column 11 is slidably connected to the inside of the lower mold 2 7, a reset component is sleeved on the outer wall of the limiting column 8, a lower hook 12 is fixedly connected to the top of the cross bar 9, an upper hook 6 is fixedly connected to the bottom of the upper mold 4, and the upper hook 6 is engaged with one end of the lower hook 12, and the reset component includes a spring 10, the spring 10 is sleeved inside the outer wall of the limiting column 8, one end of the spring 10 is fixedly connected to the inside of the shell 1, and the other end of the spring 10 is fixedly connected to the top of the cross bar 9;

[0032] Specifically, first, the output end of the hydraulic rod 3 drives the upper mold 4 to slowly descend. As the output end of the hydraulic rod 3 gradually extends out, the upper mold 4 gradually fits with the lower mold 1 5 and the lower mold 2 7, applying sufficient pressure to the plate to cause it to deform according to the shape of the mold. In this process, the metal fibers of the plate will be rearranged to obtain the required shape of the hardware. When the hardware is stamped and formed, the output end of the hydraulic rod 3 will quickly retract, driving the upper mold 4 to lift. At this time, the upper mold 4 cleverly cooperates with the upper hook 6 and the lower hook 12 to enable the cross bar 9 to rise smoothly. The rising action of the cross bar 9 further drives the ejector column 11 to extend out of the lower mold 2 7, and the formed hardware is ejected from the mold by the power of the ejector column 11.

[0033] Reference Figure 3 and Figure 4 A box body 14 is provided on one side of the shell 1, a sealing cover 15 is provided on the top of the box body 14, a connecting pipe 17 is fixedly connected inside the sealing cover 15, a coil 13 is fixedly connected inside the sealing cover 15, the outer wall of the coil 13 is passed through the lower mold 5, the other end of the coil 13 is fixedly connected to a water pump 16, the output end of the water pump 16 is fixedly connected to the other end of the water pump 16, the input end of the water pump 16 is fixedly connected to the other end of the connecting pipe 17, a semiconductor heat sink 18 is fixedly connected to one side of the box body 14, a heat conduction plate 21 arranged in a linear array is fixedly connected to one side of the semiconductor heat sink 18, a heat sink 19 arranged in a linear array is fixedly connected to the other side of the semiconductor heat sink 18, a fan 20 is fixedly connected to the other side of the semiconductor heat sink 18, and the outer wall of the heat conduction plate 21 is passed through the box body 14;

[0034] Specifically, first, a proper amount of coolant is injected into the box body 14, and the cooling surface of the semiconductor heat sink 18 generates a low temperature through a specific refrigeration technology. This low temperature is quickly transferred to the coolant in the box body 14 through the heat conduction plate 21. The heat conduction plate 21 quickly and evenly transfers the low temperature generated by the semiconductor heat sink 18 to the coolant, thereby achieving cooling of the coolant. At the same time, the heating surface of the semiconductor heat sink 18 dissipates heat through the heat sink 19. The heat sink 19 has a large surface area and can increase the contact area with the air, thereby more effectively dissipating heat into the air. In order to further improve the heat dissipation effect, the fan 20 is started to draw in external air and blow it through the heat sink 19. In this way, the air flow not only takes away the heat on the heat sink 19, but also accelerates The heat dissipation process of the heating surface of the semiconductor heat sink 18, when the coolant passes through the cooling treatment of the semiconductor heat sink 18 in the box body 14, the water pump 16 starts to play its role. The water pump 16 extracts the coolant in the box body 14 through the connecting pipe 17, and pumps it into the coil 13 through its output end. The coil 13 serves as a channel for the flow of the coolant, and guides the coolant to the surrounding of the lower mold 5, so that it flows through the mold surface for heat dissipation. In this process, the coolant absorbs the heat generated by the lower mold 5 and takes the heat away through the coil 13. Finally, the coolant that has been cooled flows back into the box body 14 through the other end of the coil 13, forming a complete cycle. This cycle process is repeated continuously, ensuring that the coolant can continuously provide a stable heat dissipation effect for the lower mold 5.

[0035] Working principle: When the stamping die of furniture hardware is used, first when stamping the hardware, the output end of the hydraulic rod 3 extends to drive the upper mold 4 to descend so that the upper mold 4 fits with the lower mold 1 5 and the lower mold 2 7 to stamp the plate, then the output end of the hydraulic rod 3 retracts to drive the upper mold 4 to lift, and at the same time, the upper mold 4 drives the cross bar 9 to rise through the cooperation of the upper hook 6 and the lower hook 12, and then the cross bar 9 drives the top column 11 to extend out of the lower mold 2 7, and the molded hardware is driven out through the top column 11 for easy removal by the operator. When the lower mold 1 5 is cooled, the box 14 is injected with coolant. Then, the cooling surface of the semiconductor heat sink 18 generates low temperature and conducts it to the box 14 through the heat conduction plate 21 to cool the coolant. The heating surface of the semiconductor heat sink 18 increases the contact area with the air through the heat sink 19, and the fan 20 sucks in external air and blows it through the heat sink 19 to assist in heat dissipation. Then, the input end of the water pump 16 draws the coolant in the box 14 through the connecting pipe 17, and then pumps it into the coil 13 through the output end of the water pump 16, so that the coolant flows through the lower mold 5 to dissipate heat, and then the coolant returns to the inside of the box 14 through the other end of the coil 13, so that the coolant circulates.
