It is necessary to first remove the upper mold and then start another ejecting mold device to eject the finished product. Then, the ejecting mold device must be closed before the next product can be processed. The entire operation process is relatively cumbersome, which reduces the processing efficiency of the equipment. Utility Model Content

[0024] Example: Refer to Figures 1 to 3A high-temperature die-casting mold for a battery pack bracket includes a bottom plate 1 and a support frame 2. The support frame 2 is fixedly mounted on one side of the top of the bottom plate 1. A lower mold 11 is fixedly mounted on the top of the bottom plate 1. A hydraulic rod 21 is fixedly mounted on the bottom of the support frame 2. An upper mold 22 is fixedly mounted on the telescopic end of the hydraulic rod 21. The upper mold 22 contacts the opposite side of the lower mold 11. An injection pipe 23 is connected to one side of the upper mold 22. A plurality of demolding components are arranged inside the lower mold 11. A cooling component is arranged inside the bottom plate 1.

[0025] The demoulding assembly includes a slide groove 3 and a driving rod 31. The slide groove 3 is provided at the bottom of the inner wall of the lower mold 11. The driving rod 31 is fixedly installed at the bottom of the upper mold 22. A spring 32 is fixedly installed at the bottom of the inner wall of the slide groove 3. A hollow top plate 33 is fixedly installed at the other end of the spring 32, and the hollow top plate 33 is slidably connected to the slide groove 3. A connecting groove 34 is provided inside the lower mold 11 and on one side of the slide groove 3. A connecting plate 35 is slidably connected inside the connecting groove 34. The connecting plate 35 is fixedly installed on one side of the bottom of the hollow top plate 33. The driving rod 31 and the opposite side of the connecting plate 35 are in contact with each other. When in use, the hydraulic rod 21 is started, and the telescopic end is used to push the upper mold 22 downward so that the driving rod 31 at its bottom is inserted into the corresponding connecting groove 34. The upper mold 22 is pressed against the top of the mold 11 and the lower mold 11 is pressed against the top of the mold 11. The upper mold 22 is pressed against the top of the mold 11 and the lower mold 11 is pressed against the top of the mold 11. The lower mold 11 is pressed against the top of the mold 11 and the lower mold 11 is pressed against the top of the mold 11. The lower mold 11 is pressed against the top of the mold 11 and the upper mold 22 is pressed against the top of the mold 11.

[0026] A plurality of limit columns 4 are fixedly installed in a rectangular array on the top of the base plate 1, and a plurality of limit blocks 41 are fixedly installed in a rectangular array on the outer surface of the upper mold 22. Each limit block 41 is movably mounted on the outer side of the limit column 4, so as to position the upper mold 22 and prevent the position of the upper mold 22 from being offset, thereby improving the stability of the movement of the upper mold 22.

[0027] The cooling assembly includes a water tank 5 fixedly installed at the bottom of the bottom plate 1, a water pump 51 is arranged at the bottom of the inner wall of the water tank 5, the water outlet of the water pump 51 is connected with a three-way pipe 52, both ends of the three-way pipe 52 are connected with connecting pipes 53, the other ends of the two connecting pipes 53 pass through the water tank 5, the bottom plate 1, and the lower mold 11, and are connected to the opposite side of the lower mold 11, a cooling cavity 54 is opened inside the lower mold 11, and a return pipe 55 is connected to the bottom of the cooling cavity 54, the other end of the return pipe 55 passes through the bottom plate 1 and the water tank 5, and a cooler 56 is fixedly installed at the end, and the return pipe 55 is fixedly installed at the water tank 5. When cooling is required, the water pump 51 is started to transfer the cold water in the water tank 5 to the cooling chamber 54 opened in the lower mold 11 through the connecting pipe 53. Since the two connecting pipes 53 are connected to the opposite sides of the lower mold 11, convection is formed inside, which can promote the heat exchange between the cold water and the lower mold 11 and improve the cooling efficiency of the equipment. Then, the water in the cooling chamber 54 flows into the cooler 56 through the return pipe 55 arranged below, and is cooled by the cooler 56 to become cold water and enter the inside of the water tank 5 again, forming a cycle.

[0028] One side of the water tank 5 is connected to a water inlet pipe 6, the bottom of the water tank 5 is connected to a water outlet pipe 61, a control valve is provided on the outside of the water outlet pipe 61, and an observation window 62 is provided on the front side of the water tank 5. The staff can observe the water level changes inside the water tank 5 through the observation window 62. When the water volume is small, the water tank 5 is filled with water through the water outlet pipe 61. When the processing is completed, the control valve outside the water outlet pipe 61 is opened to discharge the internal water.

[0029] A magnet 7 is provided on the side where the driving rod 31 and the connecting plate 35 are close to each other, and the two magnets 7 attract each other. Through the mutual cooperation between the two magnets 7, when the driving rod 31 moves upward, it can drive the connecting plate 35 to move at the same time. Since the connecting plate 35 is fixedly installed on one side of the hollow top plate 33, it can drive the hollow top plate 33 to move at the same time, which is convenient for ejecting the finished product inside, thereby improving the demoulding efficiency of the equipment.

[0030] There are four demoulding components, which are distributed in a rectangular array inside the lower mold 11. The hollow top plate 33 adopts a design that is wide at the top and narrow at the bottom. The slide 3 and the hollow top plate 33 match each other. By setting up four demoulding components distributed in a rectangular array, the finished product can be ejected quickly, thereby improving the demoulding efficiency of the equipment. Since both the hollow top plate 33 and the slide 3 adopt a design that is wide at the top and narrow at the bottom, the hollow top plate 33 can be limited. When the hollow top plate 33 is at the bottom of the slide 3, the surface of the hollow top plate 33 is flush with the bottom of the inner wall of the lower mold 11, thereby ensuring the quality of mold forming.

[0031] The working principle of the utility model is as follows: when in use, the hydraulic rod 21 is started, and the upper mold 22 is pushed downward by the telescopic end. During the movement, the driving rod 31 at the bottom is driven to move at the same time, so that it is inserted into the corresponding connecting groove 34 and the internal connecting plate 35 is squeezed. Since the connecting plate 35 is fixed on one side of the hollow top plate 33, it can drive the hollow top plate 33 to move at the same time until the bottom of the upper mold 22 contacts the top of the lower mold 11. At this time, the hollow top plate 33 is at the bottom of the slide groove 3, and the top is flush with the bottom of the inner wall of the lower mold 11. Then, the molten metal is injected into the cavity between the lower mold 11 and the hydraulic rod 21 through the injection pipe 23. Then, the water pump 51 is started to fill the water tank The cold water inside is transferred to the cooling cavity 54 provided in the lower mold 11 through the connecting pipe 53. Since the two connecting pipes 53 are connected at the opposite side of the lower mold 11, convection is formed inside, which can promote the heat exchange between the cold water and the lower mold 11, and improve the cooling efficiency of the equipment. When the finished product inside needs to be demoulded after cooling, the telescopic end of the hydraulic rod 21 is controlled to be retracted, so that the upper mold 22 drives the driving rod 31 at the bottom to move upward at the same time, and the magnet 7 set between the driving rod 31 and the connecting plate 35 and the elastic force of the spring 32 are used to jointly push the hollow top plate 33 to move upward, so that the finished product inside can be ejected, which is convenient for the staff to demould the processed finished product, and effectively improves the processing efficiency of the equipment.
