The limit rod 5 is used to limit the movement path of the upper mold 1;
[0025] Specifically, when using the automobile valve forming mold, the staff first replaces the internal components of the automobile valve forming mold through the fixing device 6 and the limiting device 8 according to the specifications of the automobile valve to be produced, and then drives the upper mold 1 to drive the upper module 2 to move through the power device. When the upper mold 1 and the lower mold 3 are in contact with each other, the upper module 2 and the lower module 4 are in contact with each other at the same time. At this time, the staff injects the molten metal into the interior of the automobile valve forming mold through the casting port, and then uses the cooling device 7 to cool the molten metal. When the metal part is cooled and formed, the automobile valve is demolded by the demolding device 9. Finally, the staff takes out the formed automobile valve to complete the operation.
[0026] Embodiment 2: By Figure 1 , 2 As can be seen from Figure 3, the fixing device 6 includes: two first shells 601, which are respectively installed on the inner walls of both sides of the upper mold 1; two buttons 602, which are respectively installed inside the two first shells 601; two cams 603, which are respectively installed inside the two first shells 601 and plugged with the inner walls of the two buttons 602; two cross bars 604, which are respectively installed inside the two first shells 601 and plugged with the inner walls of the two cams 603; two first springs 605, which are respectively sleeved on the outer walls of the two cross bars 604 and pressed against the inner walls of the two first shells 601; The inner wall of the shell 601 is provided with a plurality of saw teeth, and grooves are processed between the saw teeth. The outer wall of the button 602 is provided with a plurality of raised small squares, which can move in the inner wall grooves of the first shell 601 when subjected to force, and the bottom is a sawtooth structure. The cam 603 is the only rotatable component in the fixing device 6, and the outer wall is provided with 4 saw teeth, which can move on the edge saw teeth of the first shell 601. The outer wall of the cross bar 604 is provided with two protrusions for limiting the first spring 605; wherein, the button 602 can drive the cam 603 to make the cross bar 604 compress the first spring 605 to perform telescopic movement inside the first shell 601;
[0027] In the specific implementation process, it is worth pointing out that the inner wall of the first housing 601 is provided with a plurality of saw teeth, and grooves are processed between the saw teeth, the outer wall of the button 602 is provided with a plurality of raised small squares, which can move in the inner wall grooves of the first housing 601 when subjected to force, and the bottom is a sawtooth structure, the cam 603 is the only rotatable component in the fixing device 6, and the outer wall is provided with 4 saw teeth, which can move on the edge saw teeth of the first housing 601, and the outer wall of the cross bar 604 is provided with two protrusions for limiting the first spring 605;
[0028] Specifically, based on the above-mentioned embodiment 1, when the staff replaces the upper module 2, they first press the button 602, and the button 602 moves toward the cam 603 after being subjected to force. When the cam 603 is subjected to force, the saw teeth will convert the linear motion into rotational motion. When it moves to the sawtooth edge of the first shell 601, the sawtooth of the cam 603 is about to leave the slide rail. When the movement continues, the cam 603 will slide into the sawtooth of the button 602. At this time, the staff releases the button 602, and the sawtooth of the cam 603 is separated from the first shell 601. The contact of the serrated edge of the shell 601 increases the rotation amplitude. When the serrated edge of the cam 603 disengages from the serrated edge of the button 602 and slides again until the serrated edge of the cam 603 is located in the middle position of the serrated edge of the first shell 601, the cam 603 and the first shell 601 complete the fixing operation. At the same time, the cross bar 604 is compressed by the force of the first spring 605 to fix the upper module 2. When preparing to replace the upper module 2, the staff can follow the above steps to retract the cross bar 604 and cancel the fixing operation of the upper module 2.
[0029] Embodiment 3: By Figure 1 and 2 It can be seen that the cooling device 7 includes: a water inlet pipe 701, which is connected to the upper side of the lower mold 3; a cavity 702, which is processed inside the lower mold 3; a drain pipe 703, which is connected to the side of the lower mold 3 away from the water inlet pipe 701; the water inlet pipe 701 is connected to the external water supply device, and then the external cooling water can be transported into the cavity 702 to achieve the cooling of the automobile valve; wherein, the external cooling water can be transported into the cavity 702 through the water inlet pipe 701, and then discharged from the drain pipe 703;
[0030] 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 702 to achieve the cooling of the automobile valve;
[0031] Specifically, based on the above-mentioned embodiment 1, when the automobile valve 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 702 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 703 to complete the work.
[0032] Embodiment 4: By Figure 1 , 2As can be seen from Figure 4, the limiting device 8 includes: two second shells 801, which are respectively installed inside the lower mold 3; two cross plates 802, which are respectively installed inside the two second shells 801 and are respectively plugged into the inner wall of the lower mold 3; four second springs 803, which are respectively installed inside the two second shells 801 and respectively pressed against the outer walls of the two cross plates 802; the cross plate 802 can move inside the second shell 801 when subjected to force, and the cross plate 802 can be inserted into the groove processed by the lower module 4. The cross plate 802 can limit the lower module 4 through the second spring 803 when not interfered by external force; wherein, the cross plate 802 moves inside the second shell 801 to compress the second spring 803 to release the limit;
[0033] In the specific implementation process, it is worth pointing out that the horizontal plate 802 can move inside the second housing 801 when subjected to force, and the horizontal plate 802 can be inserted into the groove processed by the lower module 4. The horizontal plate 802 can limit the lower module 4 through the second spring 803 when not interfered by external force;
[0034] Specifically, on the basis of the above-mentioned embodiment 1, when the staff replaces the lower module 4, the staff first pulls out the cross plate 802 through the groove. After the cross plate 802 is subjected to force, it will move inside the second shell 801 and compress the second spring 803 until the outer wall of the cross plate 802 is separated from the groove of the lower module 4. The staff can then take out the lower module 4 and replace it with a new lower module 4. At this time, the staff slowly releases the cross plate 802. At this time, the force on the second spring 803 becomes smaller and smaller until the worker completely releases the cross plate 802. The second spring 803 is no longer subjected to force and returns to its initial shape, and pushes the cross plate 802 to move into the groove of the lower module 4, and finally completes the limiting operation.
[0035] Embodiment 5: By Figure 1 and 2 It can be seen that the demoulding device 9 includes: two bases 901, which are respectively installed inside the lower mold 3; two seesaws 902, which are respectively connected to the inner walls of the two bases 901 through rotating shafts; two third springs 903, which are respectively installed at the bottoms of the two seesaws 902 and fixedly connected to the inner wall of the lower mold 3; when the seesaw 902 is subjected to force, the two ends of the seesaw 902 can move in opposite directions through the base 901, and movable blocks are respectively installed on both sides of the bottom of the lower module 4, and the movable blocks can move on the inner wall of the lower module 4 when subjected to force; wherein, the seesaw 902 can be demoulded through the base 901, and the third spring 903 supports the seesaw 902;
[0036] In the specific implementation process, it is worth pointing out that when the seesaw 902 is subjected to force, the two ends of the seesaw 902 can move in opposite directions through the base 901, and movable blocks are respectively installed on both sides of the bottom of the lower module 4, and the movable blocks can move on the inner wall of the lower module 4 when subjected to force;
[0037] Specifically, based on the above-mentioned embodiment 1, when performing the demolding operation, the staff steps on the seesaw 902. Since the seesaw 902 is connected to the inner wall of the base 901 through a rotating shaft, the stepped end of the seesaw 902 is forced to move downward, and the seesaw 902 away from the stepped end begins to move upward. When the outer wall of the seesaw 902 fits with the bottom of the movable block, the staff continues to apply force to the seesaw 902 until the seesaw 902 lifts the movable block. At the same time, the movable block will lift the formed automobile valve, and the staff can remove the automobile valve. After removing it, the seesaw 902 is released. At this time, the movable block is no longer under force and returns to its initial position. At this time, the third spring 903 begins to support the seesaw 902 to prevent the seesaw 902 from tilting when the demolding operation is not performed.
