Description

Technical Field

[0001] This application belongs to the technical field of automotive contour casting, and particularly relates to a bottom die cooling plate for a gravity casting mold of an automotive wheel hub. Background Art

[0002] Gravity casting of automotive molds refers to the process in which molten metal is injected into a mold under the action of the earth's gravity to form a casting. This casting method utilizes the earth's gravity to make the molten metal flow naturally into each part of the mold, thereby forming the required casting. It is often used in the production of various non-ferrous castings, including the manufacture of automotive parts. During the casting process, the molten metal needs to be cooled by a bottom die cooling plate.

[0003] For the existing bottom die cooling plates of contour gravity casting molds, most of them have low cooling efficiency. When producing contours, it often takes a long time to cool, which will greatly reduce the production efficiency of contours, thereby increasing production costs and reducing production benefits, and is not efficient to use.

[0004] Therefore, we propose a bottom die cooling plate for a gravity casting mold of an automotive wheel hub to solve the above problems. Utility Model Content

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-4 , a bottom die cooling plate for gravity casting mold of automobile wheel hub, including a bottom die body 1, a cooling pipe 2 is arranged inside the bottom die body 1, two fixing holes 10 are opened inside the bottom die body 1, and an inverse die groove 11 is opened on the upper surface of the bottom die body 1. The top die can be conveniently installed and disassembled by relying on the fixing holes 10, which increases the production efficiency. At the same time, the shape of the formed wheel hub is controlled by using the inverse die groove 11, which improves the use effect.

[0024] The bottom surface of the bottom die body 1 is fixedly connected with a liquid storage tank 3, and the outer surface of the bottom die body 1 is fixedly connected with a support cylinder 12. The outer surface of the support cylinder 12 is fixedly connected with a mounting plate 13. By the cooperation of the support cylinder 12 and the mounting plate 13, the convenience of fixing the position of the bottom die body 1 can be improved, and the stability of the bottom die body 1 during use is increased by relying on the support cylinder 12.

[0025] The outer surface of the support cylinder 12 is fixedly connected with a firm ring 14. The bottom end of the firm ring 14 is fixedly connected with the upper surface of the mounting plate 13. The firm ring 14 can increase the fixed connection area between the support cylinder 12 and the mounting plate 13, make the connection relationship between the two more firm, prevent the connection between the two from cracking after long-term use, and increase the durability of the device.

[0026] One end of the cooling pipe 2 is fixedly communicated with the upper surface of the liquid storage tank 3. Two auxiliary handles 15 are fixedly connected to the upper surface of the mounting plate 13. A rubber sleeve 16 is fixedly connected to the outer surface of each auxiliary handle 15. Through the cooperation of the auxiliary handle 15 and the rubber sleeve 16, a good force-bearing position can be provided for the mounting plate 13, which increases the convenience when the position of the device needs to be changed. At the same time, the rubber sleeve 16 can increase the anti-slip effect when lifting or moving the device.

[0027] Two stabilizing rings 17 are fixedly connected to the outer surface of each auxiliary handle 15. The bottom ends of each group of stabilizing rings 17 are fixedly connected to the upper surface of the mounting plate 13. The stabilizing rings 17 can increase the fixed connection area between the auxiliary handle 15 and the mounting plate 13, making the connection relationship between the two more firm, preventing the connection from breaking after long-term use, and increasing the service life of the device.

[0028] An auxiliary water pump 4 is arranged inside the liquid storage tank 3. The other end of the cooling pipe 2 penetrates through the liquid storage tank 3 and is fixedly communicated with the water outlet end of the auxiliary water pump 4. A support block 18 is fixedly connected to the outer surface of the auxiliary water pump 4. The bottom surface of the support block 18 is fixedly connected to the inner bottom wall of the liquid storage tank 3. The support block 18 can play a role in supporting the auxiliary water pump 4, providing a good support point for the auxiliary water pump 4, improving the stability of the auxiliary water pump 4 during operation, and further increasing the stability during use.

[0029] Four auxiliary cylinders 5 are fixedly connected to the bottom surface of the liquid storage tank 3. A semiconductor refrigeration sheet 6 and a heat dissipation fan 9 are respectively fixedly connected to the inner wall of each auxiliary cylinder 5. A heat dissipation fin 7 is fixedly connected to the bottom surface of each semiconductor refrigeration sheet 6. A plurality of ventilation holes 8 arranged at equal intervals are formed in the outer surface of each auxiliary cylinder 5. A reinforcing block 19 is fixedly connected to the outer surface of each auxiliary cylinder 5. The upper surface of each reinforcing block 19 is fixedly connected to the bottom surface of the liquid storage tank 3. The reinforcing block 19 can increase the fixed connection area between the auxiliary cylinder 5 and the liquid storage tank 3, improve the firmness of the connection between the two, increase the service life of the auxiliary cylinder 5, and reduce the aging speed of the auxiliary cylinder 5.

[0030] The working principle of the present utility model is as follows: During use, first connect the auxiliary water pump 4, the semiconductor refrigeration sheet 6, the heat dissipation fin 7 and the heat dissipation fan 9 to the power supply, and lift the bottom die body 1 to a suitable position through the auxiliary handle 15. The stabilizing ring 17 can increase the firmness of the auxiliary handle 15. Then, rely on the cooperation of the support cylinder 12 and the mounting plate 13 to fix the bottom die body 1. When it is necessary to cool the bottom die body 1, start the auxiliary water pump 4 and the semiconductor refrigeration sheet 6. Use the suction force generated by the auxiliary water pump 4 to pump the coolant inside the liquid storage tank 3 into the cooling pipe 2, and rely on the cooling pipe 2 to flow inside the bottom die body 1, and finally transmit it back to the liquid storage tank 3 again. During the flow of the coolant inside the bottom die body 1, it can effectively absorb the heat generated by the bottom die body 1, and cool the liquid storage tank 3 by generating a certain power of refrigeration on the upper surface of the semiconductor refrigeration sheet 6, thereby cooling the coolant inside the liquid storage tank 3, preventing the coolant temperature from being too high and reducing the heat absorption effect. At the same time, rely on the heat dissipation fin 7 and the ventilation hole 8 to timely discharge the heat generated during the operation of the semiconductor refrigeration sheet 6, and use the suction force generated when the heat dissipation fan 9 rotates to further improve the heat dissipation effect, achieving the purpose of efficient heat dissipation, effectively increasing the production efficiency, and saving the production cost.
