A valve is a basic component in a piping system and is generally composed of a valve body, a valve cover, a valve core, and other structures. It has various styles and functions and a wide range of uses. Some valve bodies are formed by casting during the production process. During casting, the punch and the die are combined with each other, and the raw material in the feed cavity enters the die, and then the punch and the die cooperate to form the valve body.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, this embodiment provides an embodiment of a casting device for valve casting.

After the replacement is completed, the die 3 is placed on the workbench 1, and the cross hole 6 on the fixed plate 5 is aligned with the cross hole 6 on the workbench 1. Then the insertion rod 7 is inserted into the cross hole 6 until the cross block 8 moves to the top of the fixed plate 5, and the cross block 8 is rotated to a state where the angle is perpendicular to the cross hole 6. At this time, the insertion rod 7 can tighten the fixed plate 5 and the workbench 1 under the elastic action of the first spring 9, thereby fixing the die 3 on the workbench 1, completing the replacement of the die 3, thereby increasing the scope of application of the device.

[0027] One end of the insertion rod 7 is provided with a plurality of tooth grooves 10 . The provision of the tooth grooves 10 can increase the friction force at one end of the insertion rod 7 , making it easier to pull the insertion rod 7 .

[0028] A plurality of first electric telescopic rods 11 are fixedly installed inside the workbench 1, and a plurality of limit blocks 12 connected to the first electric telescopic rods 11 are fixedly installed on the die 3. By setting the first electric telescopic rods 11 and the limit blocks 12, the plurality of first electric telescopic rods 11 are started at the same time and extended into the limit blocks 12, so that the die 3 can be clamped and fixed, thereby preventing the die 3 from shaking when the punch 2 is pressed down, causing defects or damage to the valve.

[0029] A plurality of second electric telescopic rods 13 are fixedly installed on the workbench 1, and a push plate 14 is installed at the output end of the second electric telescopic rods 13. An arc-shaped hole 15 adapted to the push plate 14 is opened on the punch 2. Through the arrangement of the second electric telescopic rods 13, the push plate 14 and the arc-shaped hole 15, the plurality of second electric telescopic rods 13 are started to drive the push plates 14 to descend until the push plates 14 descend to the bottom of the punch 2 through the arc-shaped hole 15, so that the valve stuck on the punch 2 after casting is completed can be pushed to make it fall, without the need for personnel to manually deduct the valve, thereby reducing the risk of injury.

[0030] A connecting block 16 is fixedly installed at the output end of the second electric telescopic rod 13, and a plurality of mounting holes 17 are provided on the connecting block 16. A second spring 18 is fixedly installed inside the mounting hole 17, and a clamping block 19 is fixedly installed at one end of the second spring 18. A clamping hole 20 is provided on the push plate 14, and a plurality of grooves for matching with the clamping block 19 are provided inside the clamping hole 20. Through the arrangement of the connecting block 16, the mounting hole 17, the second spring 18, the clamping block 19 and the clamping hole 20, the clamping hole 20 on the push plate 14 is aligned with the connecting block 16 and pushed, and the clamping block 19 is squeezed and contracted into the mounting hole 17. When the clamping block 19 moves to the position of the groove, the clamping block 19 is engaged with the groove under the elastic action of the second spring 18, and the installation of the push plate 14 and the connecting block 16 is completed. When the push plate 14 is pulled, the clamping block 19 is squeezed and contracted into the mounting hole 17, and can be disassembled and replaced when the push plate 14 is damaged.

[0031] One end of the block 19 is configured to be arc-shaped. The arc-shaped configuration of one end of the block 19 can reduce the friction on the surface of the block 19, making it easy for the block 19 to move in the hole 20, thereby facilitating the disassembly and installation of the push plate 14.

[0032] A plurality of bases 21 are arranged under the workbench 1, a plurality of pressure plates 22 slidably connected to the bases 21 are fixedly installed at the bottom of the workbench 1, a plurality of shock absorbers 23 connected to the pressure plates 22 are fixedly installed inside the pressure plates 22, and the vibrations generated during the operation of the device can be buffered by the arrangement of the bases 21, the pressure plates 22 and the shock absorbers 23, so as to prevent the parts on the device from loosening due to the vibrations and reduce the service life of the device.

[0033] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a casting device for valve casting provided in this embodiment is as follows:

[0034] When replacing the die 3, the multiple cross blocks 8 are rotated to the same angle as the cross hole 6, and then the multiple insertion rods 7 are pulled until the cross block 8 is pulled to the bottom of the workbench 1 to replace the die 3. After the replacement is completed, the die 3 is placed on the workbench 1, and the cross hole 6 on the fixed plate 5 is aligned with the cross hole 6 on the workbench 1. Then the insertion rod 7 is inserted into the cross hole 6 until the cross block 8 moves to the top of the fixed plate 5. When the cross block 8 is rotated to a state where the angle is perpendicular to the cross hole 6, the insertion rod 7 can tighten the fixed plate 5 and the workbench 1 under the elastic action of the first spring 9, thereby fixing the die 3 on the workbench 1, completing the replacement of the die 3, thereby increasing the scope of application of the device.

[0035] In summary, in the present embodiment, according to a casting device for valve casting of the present embodiment, the friction force at one end of the plug rod 7 can be increased by setting the tooth groove 10, so as to facilitate pulling the plug rod 7. By setting the first electric telescopic rod 11 and the limit block 12, a plurality of first electric telescopic rods 11 are started at the same time to extend them into the limit block 12, so as to clamp and fix the die 3, so as to prevent the die 3 from shaking when the punch 2 is pressed down, thereby causing defects or damage to the valve. By setting the second electric telescopic rod 13, the push plate 14 and the arc hole 15, a plurality of second electric telescopic rods 13 are started to drive the push plate 14 to descend, until the push plate 14 descends to the bottom of the punch 2 through the arc hole 15, so as to push the valve stuck on the punch 2 after the casting is completed to make it fall, without the need for personnel to manually deduct the valve, thereby reducing the risk of injury. By setting the connecting block 16, the mounting hole 17, the second spring 18, the clamping block 19 and the clamping hole 20, the clamping hole 20 on the push plate 14 is aligned with the When the quasi-connecting block 16 is pushed, the block 19 is squeezed and retracted into the mounting hole 17. When the block 19 moves to the position of the groove, the block 19 is engaged with the groove under the elastic action of the second spring 18, completing the installation of the push plate 14 and the connecting block 16. When the push plate 14 is pulled, the block 19 is squeezed and retracted into the mounting hole 17, and can be disassembled and replaced when the push plate 14 is damaged. The arc-shaped setting of one end of the block 19 can reduce the friction force on the surface of the block 19, so that the block 19 is easy to move in the card hole 20, which is convenient for disassembly and installation of the push plate 14. Through the setting of the base 21, the pressure plate 22 and the shock absorber 23, the vibration generated when the device is running can be buffered, and the parts on the device can be prevented from loosening due to vibration, which reduces the service life of the device. Through the setting of the base 21, the pressure plate 22 and the shock absorber 23, the vibration generated when the device is running can be buffered, and the parts on the device can be prevented from loosening due to vibration, which reduces the service life of the device.
