Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping structure for an in-mold cooling device. Background Technology

[0002] Because aluminum has a low melting point, oil-free stamping is required during stamping. During stamping production, the punch generates high temperatures, causing aluminum powder to stick to the punch and form lumps, resulting in product damage, burrs, and the punch seizing the stripper insert. This traditional structure cannot be used, and the mold must be improved and optimized. Furthermore, the efficiency of cooling and forming of stamped parts during the stamping process is low, resulting in low efficiency of continuous and stable production of injection molded parts inside the mold. Therefore, a blanket is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a stamping structure for an in-mold cooling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping structure for an in-mold cooling device, comprising a moving mold and a fixed mold, wherein the moving mold is disposed on the fixed mold, the punch is disposed in the middle of the moving mold, the injection connector tooth hole and the first flow channel hole are disposed inside the moving mold, and the injection connector tooth hole and the first flow channel hole are disposed outside the punch, the stripper plate insert and the lower die cutting edge are disposed in the middle of the fixed mold, and the stripper plate insert is located outside the lower die cutting edge, the flow groove and the second flow channel hole are disposed between the middle of the moving mold and the fixed mold, and a drive conveying pipe is disposed in the middle of the upper end of the moving mold.

[0005] Preferably, a heat dissipation frame is provided between the moving mold and the fixed mold, a discharge pipe is provided at the bottom of one end of the heat dissipation frame, a solenoid valve is fixedly installed at the middle of the outer end of the heat dissipation frame, and a conveying pipe is fixedly installed at the outer end of the solenoid valve.

[0006] Preferably, nozzles are uniformly fixedly installed on both inner ends of the fixed mold.

[0007] Preferably, the bottom end of the fixed mold is fixedly installed at the upper edge of the fixed mold, and the nozzle is located outside the contact end face of the moving mold and the fixed mold.

[0008] Preferably, the injection connector hole is the baffle coolant injection connector hole, and the first flow channel hole is the baffle coolant flow channel hole.

[0009] Preferably, the flow channel is a baffle plate coolant flow channel, and the second flow channel hole is a coolant flow channel hole for the stripper plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This product does not require oil during production, thus effectively solving the temperature problem through punch cooling. Continuous cooling of the punch using industrial alcohol and nitrogen-hydrogen eliminates the problem of punch buildup due to high temperatures, ensuring product quality. The mixed coolant of industrial alcohol and nitrogen-hydrogen is directly delivered to the area around the punch through the injection joint and first flow channel holes, quickly absorbing the high temperature and preventing aluminum powder from sticking together and forming buildup. This eliminates defects such as product damage and burrs at the source. The coolant flows through the flow channel into the second flow channel hole, specifically cooling the stripper plate insert to prevent it from jamming due to thermal expansion, ensuring the stability of continuous production. The heat dissipation frame, in conjunction with nozzles, sprays coolant, covering the contact surfaces of the moving and stationary dies, accelerating overall die heat dissipation, improving cooling efficiency, ensuring product quality and yield, eliminating buildup and deformation, and eradicating the high-temperature problem of the punch. Combined with uniform die cooling, this significantly reduces product damage, burrs, and dimensional deformation, especially meeting the stringent requirements of high-precision oil-free stamping of aluminum materials, improving production efficiency and ensuring continuous and stable production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3The present invention provides an embodiment of an in-mold cooling device stamping structure, comprising a moving mold 8 and a fixed mold 9. The moving mold 8 is disposed on the fixed mold 9. A punch 1 is disposed in the middle of the moving mold 8. An injection connector tooth hole 4 and a first flow channel hole 5 are disposed inside the moving mold 8, and the injection connector tooth hole 4 and the first flow channel hole 5 are disposed outside the punch 1. A stripper plate inlet 2 and a lower die cutting edge 3 are disposed in the middle of the fixed mold 9, and the stripper plate inlet 2 is located outside the lower die cutting edge 3. A flow channel 6 and a second flow channel hole 7 are disposed between the middle of the moving mold 8 and the fixed mold 9. A drive conveying pipe 10 is disposed in the middle of the upper end of the moving mold 8.

A solenoid valve 13 is fixedly installed in the middle of the outer end of the heat dissipation frame 11. A delivery pipe 14 is fixedly installed in the outer end of the solenoid valve 13.

[0019] The two inner ends of the fixed mold 9 are evenly fixed with nozzles 15.

[0020] The bottom end of the fixed mold 9 is fixedly installed at the upper edge of the fixed mold 9, and the nozzle 15 is located on the outside of the contact end face of the moving mold 8 and the fixed mold 9.

[0021] The injection connector hole 4 is the stop plate coolant injection connector hole, and the first flow channel hole 5 is the stop plate coolant flow channel hole.

[0023] Working principle: The closed-loop cooling system directly and actively cools the punch 1 and stripper plate insert 2, solving the problem of high-temperature buildup during oil-free aluminum stamping. The cooling medium, a mixture of industrial alcohol and nitrogen-hydrogen, circulates in the internal flow channel of the mold, continuously absorbing heat. The industrial alcohol and nitrogen-hydrogen coolant enters the mold system through the stop plate coolant injection joint thread hole 4, flows through the stop plate coolant flow channel hole 5 to the area around the punch 1, directly cooling the punch. The high-temperature punch 1 transfers heat to the coolant, preventing aluminum powder from sticking together and forming buildup. The coolant continues to flow into the stripper plate insert 2 area through the stop plate coolant flow channel 6. The coolant cools the stripper plate insert 2 through the stripper plate insert coolant flow channel hole 7, preventing it from seizing up due to high temperature. The external coolant enters the heat dissipation frame 11 through the delivery hose and delivery pipe 14 and is sprayed out from the nozzle 15 to cool the moving mold 8 and the stationary mold 9, allowing the internal stamped parts to cool down and form quickly. The solenoid valve 13 controls the coolant flow rate to ensure stable cooling.
