Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die with a rapid cooling function. Background Technology

[0002] During the production of stamping dies, the die temperature rises due to frictional heat after prolonged stamping operations. If not cooled in time, it will not only affect the precision and surface quality of the stamped parts, but may also cause the die to deform or be damaged due to overheating, shortening the die's service life. Traditional stamping die cooling methods mostly adopt single-stage cooling or simple circulation structures, which have problems such as frequent coolant replacement, low cooling efficiency, and long die cooling time, resulting in low production efficiency and difficulty in ensuring the precision stability of the die during long-term use. In addition, the heat dissipation structure of traditional cooling systems is simple, the hot water heats up slowly, and the coolant's cooling capacity recovers slowly, which cannot provide a continuous and efficient cooling effect for the die, restricting the application of stamping dies in high-frequency, high-precision production scenarios. Therefore, we have launched a new stamping die with rapid cooling function. Utility Model Content

[0003] The main purpose of this invention is to provide a stamping die with a rapid cooling function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stamping die with rapid cooling function includes a lower die box. A die groove is provided in the middle of the upper end of the lower die box. A fixing frame is fixedly installed at each of the four corners of the upper end of the lower die box through a support frame. A telescopic cylinder is inserted and fixedly installed in the middle of the upper end of the fixing frame. An upper die is fixedly installed at the output end of the telescopic cylinder through a fixing plate. A cooling mechanism is provided at the left and right ends of the lower die box. A first cavity groove is provided on the inner surface of the lower die box. A second cavity groove is provided in the lower part of the interior of the lower die box. Water passage holes are provided on the inner left and inner right walls of the second cavity groove. The first cavity groove and the second cavity groove are interconnected through the water passage holes.

[0005] Preferably, the cooling mechanism includes a cold water tank and a heat sink, which are arranged in a left-right correspondence. A water pump is fixedly installed at the upper end of both the cold water tank and the heat sink through a connecting pipe. An input pipe is provided at the upper end of the water pump located on the left, and a connecting pipe is provided at the upper end of the water pump located on the right. Several heat dissipation holes are provided at the front and rear of the upper end of the heat sink. A cross-shaped frame is provided at the upper end of the heat sink, and a cooling component is provided at the upper end of the cross-shaped frame. A delivery pipe is fixedly installed through the rear of the outer surface of both the cold water tank and the heat sink, and a valve is provided on the outer surface of the delivery pipe.

[0006] Preferably, the input pipe and the connecting pipe pass through the left and right walls of the lower mold box and extend into the interior of the first cavity groove.

[0007] By adopting the above technical solution: the through design of the input pipe and the connecting pipe provides a channel for the cooling water to enter the first cavity groove inside the lower mold box, so that the cold water can directly contact the mold part that needs to be cooled and realize heat exchange.

[0008] Preferably, the cold water tank and the heat dissipation tank are interconnected via a delivery pipe and a valve.

[0009] By adopting the above technical solution, the delivery pipe connects the cold water tank and the heat exchange tank, making it convenient to transport the water cooled by the heat exchange tank to the cold water tank for storage through the delivery pipe.

[0010] Preferably, the lower part of the cooling assembly penetrates the cross-shaped frame and the upper wall of the heat sink and extends into the interior of the heat sink.

[0011] By adopting the above technical solution, the cooling components are inserted deep into the heat dissipation tank, which can directly perform forced convection heat dissipation on the high-temperature medium inside the tank, and accelerate the dissipation of heat to the outside air.

[0012] Preferably, the cooling assembly includes a motor and two drive rods. A rotating rod is fixedly mounted on the output end of the motor. Two first pulleys are fixedly mounted on the upper outer surface of each rotating rod, arranged vertically. A cooling fan is mounted at the lower end of each drive rod, which is arranged front-to-back. The upper outer surfaces of both drive rods are rotatably connected to a cross-shaped frame via bearings. A second pulley is fixedly mounted on the upper outer surface of each drive rod. A first transmission belt is shared between the upper first pulley and the front second pulley, and a second transmission belt is shared between the lower first pulley and the rear second pulley. Three sets of stirring blades are provided on the lower outer surface of the rotating rod.

[0013] By adopting the above technical solution: the motor drives the rotating rod to rotate, which in turn drives the driving rod to rotate through the first pulley, the first transmission belt, and the second transmission belt, so that the front and rear cooling fans operate synchronously, forming multi-angle air convection, covering a larger area inside the cooling tank, improving heat dissipation efficiency, and the stirring blades facilitate stirring of hot water, thereby accelerating heat dissipation.

[0014] Preferably, the outer surfaces of the two cooling fans do not contact each other with the inner surfaces of the rotating rod and the heat sink.

[0015] By adopting the above technical solution, friction and collision between the cooling fan and the rotating rod or the inner wall of the cooling tank can be prevented when the cooling fan rotates, thus avoiding wear of the components.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A circulating cooling system is formed by components such as water pump, cold water tank, inlet pipe, connecting pipe, heat dissipation tank and delivery pipe. Cold water can quickly flow into the first cavity and second cavity of the lower mold box to cool the mold. After absorbing heat, the hot water is forced to dissipate heat through the heat dissipation tank and then flows back to the cold water tank. This avoids the drawback of the traditional cooling method that requires frequent replacement of coolant, shortens the mold cooling time, increases the usage frequency of stamping molds, and thus improves the overall production efficiency. 2. Through the cooling components, the cooling fan accelerates the dissipation of heat from the hot water in the cooling tank through air convection. At the same time, the three sets of stirring blades on the lower part of the outer surface of the rotating rod stir the hot water, accelerate the heat exchange inside the hot water, and make the hot water temperature drop rapidly. This ensures that the coolant can quickly restore its cooling capacity, providing a stable and efficient cooling effect for the mold and ensuring the accuracy and service life of the mold during long-term use.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A stamping die with rapid cooling function includes a lower die box 1. A die groove 2 is provided in the middle of the upper end of the lower die box 1. Fixing frames 3 are fixedly installed at the four corners of the upper end of the lower die box 1 through support frames. Telescopic cylinders 4 are inserted and fixedly installed in the middle of the upper end of the fixing frames 3. An upper die 5 is fixedly installed at the output end of the telescopic cylinder 4 through a fixing plate. A cooling mechanism 6 is provided at the left and right ends of the lower die box 1. A first cavity groove 7 is provided on the inner surface of the lower die box 1. A second cavity groove 8 is provided in the lower part of the interior of the lower die box 1. Water passage holes 9 are provided on the inner left and inner right walls of the second cavity groove 8. The first cavity groove 7 and the second cavity groove 8 are interconnected through the water passage holes 9.

[0023] In this embodiment, the cooling mechanism 6 includes a cold water tank 60 and a heat sink 61, which are arranged in a left-right correspondence. A water pump 62 is fixedly installed at the upper end of both the cold water tank 60 and the heat sink 61 via a connecting pipe. An input pipe 63 is provided at the upper end of the water pump 62 located on the left, and a connecting pipe 64 is provided at the upper end of the water pump 62 located on the right. Several heat dissipation holes 65 are provided at the front and rear of the upper end of the heat sink 61. A cross-shaped frame 66 is provided at the upper end of the heat sink 61. A cooling assembly 67 is provided at the end. A conveying pipe 68 is fixedly installed on the rear of the outer surface of the cold water tank 60 and the heat sink 61. A valve 69 is provided on the outer surface of the conveying pipe 68. The input pipe 63 and the connecting pipe 64 pass through the left and right walls of the lower mold box 1 and extend into the interior of the first cavity groove 7, respectively. The cold water tank 60 and the heat sink 61 are interconnected through the conveying pipe 68 and the valve 69. The lower part of the cooling assembly 67 passes through the cross-shaped frame 66 and the upper wall of the heat sink 61 and extends into the interior of the heat sink 61.

[0024] The above scheme involves feeding water into the cold water tank 60 through the inlet above the cold water tank 60. During the stamping operation, when the left-side water pump 62 is started by the control, the water pump 62 draws cold water from the cold water tank 60 and delivers it to the first cavity 7 and the second cavity 8 of the lower mold box 1 through the input pipe 63. At the same time, the hot water that has absorbed heat flows into the heat dissipation tank 61 through the connecting pipe 64. After being cooled by the cooling component 67, the valve 69 is opened by the controller, and the delivery pipe 68 connects the cold water tank 60 and the heat dissipation tank 61, so that the cooled water in the heat dissipation tank 61 can flow back to the cold water tank 60, forming a circulation loop.

[0025] In this embodiment, the cooling assembly 67 includes a motor 671 and two drive rods 674. A rotating rod 672 is fixedly mounted on the output end of the motor 671. Two first pulleys 673 are fixedly mounted on the upper part of the outer surface of the rotating rod 672, arranged vertically. A cooling fan 675 is provided at the lower end of each drive rod 674, arranged front-to-back. The upper part of the outer surface of each drive rod 674 is rotatably connected to a cross-shaped bracket 66 via bearings. Together, a second pulley 676 is fixedly installed on the upper part of the outer surface of both driving rods 674. A first transmission belt 677 is provided between the upper first pulley 673 and the front second pulley 676. A second transmission belt 678 is provided between the lower first pulley 673 and the rear second pulley 676. Three sets of stirring blades 679 are provided on the lower part of the outer surface of the rotating rod 672. The outer surfaces of the two cooling fans 675 do not contact the inner surfaces of the rotating rod 672 and the cooling tank 61.

[0026] The above scheme works as follows: the controller turns on the motor 671 to drive the rotating rod 672 to rotate. The rotation of the rotating rod 672 drives the three sets of stirring blades 679 below to rotate, stirring and dissipating heat from the water inside. At the same time, the rotating rod 672 drives the first pulley 673 on it to rotate. The first transmission belt 677 and the second transmission belt 678 drive the second pulleys 676 at the front and rear to rotate respectively. This causes the two driving rods 674 to rotate synchronously, driving the cooling fan 675 at the lower end to force heat dissipation from the hot water in the heat dissipation tank 61. The heat is dissipated to the outside through the heat dissipation holes 65, thereby achieving the purpose of cooling. During the rotation of the cooling fan 675, a gap is maintained between it and the rotating rod 672 and the inner surface of the heat dissipation tank 61 to avoid friction interference, ensuring stable and efficient acceleration of airflow and improving heat dissipation efficiency.

[0027] It should be noted that this utility model is a stamping die with a rapid cooling function. During use, when the die is stamping, the telescopic cylinder 4 drives the upper die 5 to move downward along the support frame, cooperating with the die groove 2 of the lower die box 1 to complete the stamping operation. During the stamping operation, the left water pump 62 is started by the controller, drawing cold water from the cold water tank 60 and delivering it to the first cavity groove 7 and the second cavity groove 8 of the lower die box 1 through the input pipe 63. The cold water flows between the two cavity grooves through the water hole 9, absorbing the heat of the die to cool the die groove 2. The hot water after absorbing heat flows into the heat dissipation tank 61 through the connecting pipe 64. The motor 671 drives the rotating rod 672 to rotate, driving the first pulley 6 Rotating rod 672 drives the front and rear second pulleys 676 to rotate via the first transmission belt 677 and the second transmission belt 678, respectively. This causes the two drive rods 674 to rotate synchronously, driving the cooling fan 675 at the lower end to forcibly dissipate heat from the hot water in the cooling tank 61. The heat is dissipated to the outside through the cooling holes 65. At the same time, the rotation of the rotating rod 672 drives the three sets of stirring blades 679 on the lower part of the outer surface to stir the hot water, accelerating the flow of hot water and the dissipation of heat, thus improving the heat dissipation efficiency. After cooling, the water flows back to the cold water tank 60 through the conveying pipe 68 after the controller opens the valve 69, forming a circulation loop to continuously provide cooling for the mold, ensuring the accuracy and service life of the mold during long-term use.
