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.

[0021] When the traditional valve body mold is formed, the valve body is cast, which makes the molded valve body fit tightly with the mold. When the mold is cooled, the workers take out the valve body because the valve body fits tightly with the mold, which increases the difficulty of taking out the valve body and increases the labor cost;

[0022] In view of this, the utility model provides a valve body mold. The valve body mold solves the problem that the traditional valve body is difficult to remove after cooling by casting through a cooling device and a demolding device. The cooling device can quickly cool the cast valve body, thereby reducing the required waiting time.

[0025] Specifically, when using the valve body mold, the staff first drives the upper mold 2 to descend through a power device until the upper mold 2 is fitted with the lower mold 1. At this time, the staff injects the molten metal into the upper mold 2 through the pouring port 3, and eliminates the bubbles generated during casting through the vibration device 8. The cooling device 7 is then used to cool the molten metal. When the metal part is cooled and formed, the demolding device 5 is used to demold the valve body inside the lower mold 1 and the upper mold 2. Finally, the staff takes out the formed valve body to complete the operation.

[0026] Embodiment 2: By Figure 1 , 2As can be seen from Figure 3, the demoulding device 5 includes: two limit rods 501, which are provided and are both installed above the upper mold 2; a horizontal plate 502, which is installed above the two limit rods 501; an insertion rod 503, which is plugged into the inner wall of the horizontal plate 502; a demoulding rod 504, which is installed on the outer wall of the insertion rod 503 and is plugged into the inner wall of the horizontal plate 502; a rotating rod 505, which is rotatably connected to the inner wall of the lower mold 1 through a bearing; a first bevel gear 506, which is installed on one side of the rotating rod 505; a second bevel gear 507, which is meshed and connected to the outer wall of the first bevel gear 506; a threaded rod 508, which is installed on the inner wall of the second bevel gear 507, and is rotatably connected to the inner wall of the lower mold 1 through a bearing; a demoulding plate 509, which is provided The second bevel gear 507 can convert the lateral force on the first bevel gear 506 into a vertical force, and the demoulding operation is completed by changing the direction of the force. When the threaded rod 508 is subjected to force, it can rotate on the inner wall of the lower mold 1 through the bearing. The two ends of the demoulding plate 509 are plugged with the lower mold 1 through the limit columns, so that the demoulding plate 509 can only move in a specified direction when subjected to force; wherein the insertion rod 503 can limit the demoulding rod 504 through the horizontal plate 502, and the rotating rod 505 can drive the first bevel gear 506 to drive the second bevel gear 507 to rotate, thereby causing the threaded rod 508 to drive the demoulding plate 509 to move upward to perform the demoulding operation;

[0027] In the specific implementation process, it is worth pointing out that the second bevel gear 507 can convert the lateral force on the first bevel gear 506 into a vertical force, and complete the demoulding operation by changing the direction of the force. When the threaded rod 508 is subjected to force, it can rotate on the inner wall of the lower mold 1 through the bearing.

[0028] Furthermore, vertical rods 6 are respectively installed at the four corners of the top of the upper mold 2 and are fixedly connected to the outer wall of the lower mold 1;

[0029] Specifically, on the basis of the above-mentioned embodiment 1, the worker first pulls out the insertion rod 503 from the inner wall of the horizontal plate 502. At this time, the demoulding rod 504 is no longer limited by the insertion rod 503. Then the worker presses the demoulding rod 504 downward, and the upper valve body is separated from the upper mold 2 by force. The worker first takes the upper valve body out of the upper mold 2, and then rotates the rotating rod 505. The rotating rod 505 is rotated by force and drives the first bevel gear 506 to rotate at the same time. When the first bevel gear 506 rotates, it will drive the second bevel gear 507. At the same time, the first bevel gear 506 will convert the lateral force it receives into a vertical force through the second bevel gear 507. The second bevel gear 507 drives the threaded rod 508 to rotate upward. At this time, the demoulding plate 509 threadedly connected to the threaded rod 508 is forced to be lifted up, and then the lower valve body inside the lower mold 1 is demoulded. Finally, the worker takes out the lower valve body.

[0031] In the specific implementation process, it is worth pointing out that the water inlet pipe 701 is connected to the external water supply device, so that the external cooling water can be transported into the cavity 703 to achieve cooling of the valve body;

[0032] Specifically, based on the above-mentioned embodiment 1, when the valve body needs to be cooled, the staff turns on the external water supply equipment connected to the water inlet pipe 701. At this time, the cooling water is introduced into the interior of the cavity 703 through the water inlet pipe 701. At this time, the metal parts can be cooled by heat conduction, and then the cooling water is discharged from the drain pipe 702 to complete the work.

[0033] Embodiment 4: By Figure 1 , 2 As can be seen from Figure 4, the vibration device 8 includes: a base 801, which is arranged below the lower mold 1; a slide rail 802, which is installed above the base 801; a slider 803, which is slidably connected to the outer wall of the slide rail 802; two heat insulation boxes 804 are provided, and are respectively installed on both sides of the outer wall of the slider 803; two vibration motors 805 are provided, and are respectively provided inside the two heat insulation boxes 804; two limit blocks 807 are provided, both of which are installed above the base 801; two cross bars 806 are provided, which are respectively installed on the outer walls of the two heat insulation boxes 804, and are respectively plugged into the inner walls of the two limit blocks 807; two springs 808 are provided, which are respectively installed The base 801 supports the whole device, and the slider 803 can slide along the outer wall of the slide rail 802 when it is stressed.

When the cross bar 806 is stressed, it can reciprocate through the limit block 807 and the spring 808. Among them, the vibration motor 805 can drive the heat insulation box 804 to drive the slider 803 to slide along the outer wall of the slide rail 802, and at the same time, the cross bar 806 compresses the spring 808 inside the limit block 807 to reciprocate.

When the crossbar 806 is subjected to force, it can reciprocate through the limit block 807 and the spring 808;

[0035] Specifically, on the basis of the above-mentioned embodiment 1, when the staff is ready to remove the bubbles generated in the mold due to casting, the workers can start the vibration motor 805 through an external power supply. After the vibration motor 805 is powered on, it will drive the heat insulation box 804 to vibrate, and the heat insulation box 804 will transfer the force received to the slider 803, so the slider 803 is forced to slide along the outer wall of the slide rail 802, thereby driving the lower mold 1 and the upper mold 2 to move. At this time, the bubbles inside the mold are removed due to the vibration, and when the vibration motor 805 drives the heat insulation box 804 to move, the cross bar 806 on the outer wall of the heat insulation box 804 will be forced to move at the same time, and compress the spring 808 inside the limit block 807, and reciprocate through the spring 808.
