[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1, please refer to Figures 1-4 A casting device for a brass fire-fighting butterfly valve, comprising: The base 100 has a fixed template 200 mounted on its top. The movable template 300 is mounted on the top of the base 100 and is driven by a linear motor. The top of the base 100 is equipped with a cleaning pipe 400, and the side of the fixed template 200 is equipped with a through coolant pipe 500. The moving template 300 is fitted with a fixed platform 601 on its side. The fixed template 200 is connected to a connecting rod 608 via an elastic telescopic rod 609 on its side. A top rod 610 is fitted on the side of the connecting rod 608. A transmission component for transmission is fitted between the fixed platform 601 and the top rod 610. The transmission component includes an elastic telescopic rod 602 fitted on the side of the fixed platform 601. A limiting block 603 is fitted on the side of the telescopic end of the elastic telescopic rod 602. There are two limiting blocks 603, which are symmetrical about the central axis of the fixed platform 601. A fixed block 604 is fixedly connected to the top of the base 100. The linear motor is activated, driving the moving template 300 driven by the linear motor to move towards the fixed template 200, and performing the corresponding casting and forming operation on the space located in the fixed template 200. During this process, the fixed platform 601 mounted on the moving template 300 moves together, causing the fixed platform 601 to drive the elastic telescopic rod 602 and the limiting block 603 to move towards the side closer to the fixed block 604.

[0020] A fixing rod 605 is fixedly connected to the side of fixing block 604, and a fixing block 606 is fixedly connected to the side of fixing rod 605. When the limiting block 603 moves to the fixing block 606, the limiting block 603 is restricted by the fixing block 606, which compresses the elastic telescopic rod 602 and moves it to the side of the fixing platform 601, so that the limiting block 603 can pass over the fixing block 606.

[0021] A sliding block 607 is slidably connected to the outer side of the fixed rod 605. When the limiting block 603 moves to the sliding block 607, the sliding block 607 is restricted by the fixed block 604 and cannot move. Similarly, the limiting block 603 moves past the sliding block 607 to the position between the fixed block 604 and the sliding block 607. At the same time, the moving template 300 and the fixed template 200 are attached to each other and the casting operation is performed.

[0022] The connecting rod 608 is located at the top of the sliding block 607 and is fixed to the sliding block 607. After the corresponding casting operation is completed, the moving template 300 is reset, and the fixed platform 601, the elastic telescopic rod 602, and the limiting block 603 are reset together. The limiting block 603 presses the sliding block 607 from the other side. At this time, the sliding block 607 is not restricted, so that during the reset process, the limiting block 603 can drive the sliding block 607 to move on the fixed rod 605 towards the fixed block 606. The sliding block 607 drives the connecting rod 608 fixedly connected to it to move, so that the connecting rod 608 drives the top rod fixedly connected to it to move. The mechanism 610 moves to eject the brass fire-fighting butterfly valve, which has completed its casting process within the fixed mold 200. When the limiting block 603 moves the sliding block 607 to the fixed block 606, the sliding block 607 is restricted by the fixed block 606 and cannot move further. The limiting block 603 then compresses the elastic telescopic rod 602, causing it to move and pass over the sliding block 607 and the fixed block 606. Subsequently, the sliding block 607 and the connecting rod 608 become ineffective and can be reset by the elastic telescopic rod 609. In this way, the brass fire-fighting butterfly valve can be ejected from the fixed mold 200 after the casting process is completed, reducing the possibility of the brass fire-fighting butterfly valve remaining attached to the fixed mold 200.

[0023] In use, the linear motor is activated, driving the moving template 300 to move towards the fixed template 200. This allows for the casting and molding of the material within the fixed template 200. During this process, the fixed platform 601 mounted on the moving template 300 moves along with it, causing the elastic telescopic rod 602 and the limiting block 603 to move closer to the fixed block 604. When the limiting block 603 reaches the fixed block 606, it is restrained by the fixed block 606, thus compressing the elastic telescopic rod. The retracting rod 602 moves towards the fixed platform 601, allowing the limiting block 603 to pass over the fixed block 606. When the limiting block 603 moves to the sliding block 607, the sliding block 607 is restricted by the fixed block 604 and cannot move. Similarly, the limiting block 603 moves over the sliding block 607 to a position between the fixed block 604 and the sliding block 607. At the same time, the moving template 300 and the fixed template 200 are attached to each other and the casting operation is performed. After the corresponding casting operation is completed, the moving... Template 300 then resets, and the fixed platform 601, elastic telescopic rod 602, and limiting block 603 reset together. Limiting block 603 presses against sliding block 607 from the other side. At this time, sliding block 607 is not restricted, allowing limiting block 603 to move sliding block 607 from fixed rod 605 to fixed block 606 during the reset process. Sliding block 607 then moves connecting rod 608, which is fixedly connected to it, causing connecting rod 608 to move top rod 610, which is fixedly connected to it. The brass fire butterfly valve, which has been cast and shaped within the fixed template 200, is ejected. When the limiting block 603 moves the sliding block 607 to the fixed block 606, the sliding block 607 is restricted by the fixed block 606 and cannot move further. The limiting block 603 then compresses the elastic telescopic rod 602 and moves, causing the limiting block 603 to pass over the sliding block 607 and the fixed block 606 in sequence. Subsequently, the sliding block 607 and the connecting rod 608 lose their function and can be reset under the action of the elastic telescopic rod 609.

[0024] Example 2, please refer to Figures 1-6Based on Embodiment 1, a cooling assembly 700 for inputting coolant is installed inside the coolant pipe 500. The cooling assembly 700 includes a hydraulic chamber 701 mounted on the side of the fixed template 200. One end of the hydraulic chamber 701 is slidably connected to a force-bearing rod 702 via a piston. When the limiting block 603 moves past the sliding block 607 to the position between the fixed block 604 and the sliding block 607, that is, when the moving template 300 and the fixed template 200 are in contact and casting is being performed, the fixed platform 601 moves to the force-bearing rod 702 and drives the force-bearing rod 702 to move to the side. In conjunction with the hydraulic chamber 701 slidably connected to the force-bearing rod 702 via a piston, the force-bearing rod 702 compresses the oil stored in the bottom of the hydraulic chamber 701 during the movement.

[0025] The other end of the hydraulic chamber 701 is slidably connected to a transmission rod 703 via a piston. A spring 704 is mounted on the side of the force-bearing rod 702. The end of the spring 704 away from the force-bearing rod 702 is mounted on the inner wall of the hydraulic chamber 701. A through rotating rod 705 is rotatably connected inside the coolant pipe 500. The rotating rod 705 is located on the side of the transmission rod 703 and is fixed to the transmission rod 703. A block 706 is mounted on the side of the rotating rod 705. When the oil stored in the hydraulic chamber 701 is compressed, the oil flows towards the side closer to the transmission rod 703, causing the transmission rod 703, which is slidably connected to the hydraulic chamber 701 via a piston, to extend out of the hydraulic chamber 701. The transmission rod 703 then drives the rotating rod 705, which is fixedly connected to it, to rotate at a certain angle. This causes the rotating rod 705 to rotate the block 706, which is fixedly connected to it, opening the coolant pipe 500, which was originally blocked by the block 706. In this case, the coolant pipe 500 can be opened, and the corresponding coolant can be pumped into the coolant pipe 500 through the liquid pump to perform the corresponding cooling operation on the cast brass fire butterfly valve, making the device easier to use.

[0026] When the fixed platform 601 is reset along with the moving template 300, the force-bearing rod 702 loses the function of the fixed platform 601 and can be reset under the action of the spring 704.

[0027] In use, based on Embodiment 1, when the limiting block 603 moves past the sliding block 607 to the position between the fixed block 604 and the sliding block 607, that is, when the moving template 300 and the fixed template 200 are in contact and casting is being performed, the fixed table 601 moves to the force-bearing rod 702 and drives the force-bearing rod 702 to move to the side. This, combined with the hydraulic chamber 701 connected to the force-bearing rod 702 via a piston sliding connection, causes the force-bearing rod 702 to compress the oil stored in the bottom of the hydraulic chamber 701 during its movement. The oil then flows towards the side closer to the transmission rod 703, driving the oil flow between the hydraulic chamber 701 and the force-bearing rod 702. A transmission rod 703, which is slidably connected to a piston, extends from the hydraulic chamber 701. The transmission rod 703 then drives the rotating rod 705, which is fixedly connected to it, to rotate at a certain angle. This causes the rotating rod 705 to rotate the block 706, which is fixedly connected to it, thus opening the coolant pipe 500, which was originally blocked by the block 706. In this case, the coolant pipe 500 can be opened, and the corresponding coolant can be introduced into the coolant pipe 500 by the liquid pump. When the fixed platform 601 is reset along with the moving template 300, the force rod 702 loses the function of the fixed platform 601 and can be reset under the action of the spring 704.

[0028] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary cleaning component 800 for improving the cleaning effect is installed on the top of the base 100. The auxiliary cleaning component 800 includes a rotating rod 2 801 rotatably connected to the base 100. An impeller 802 and a sprocket 1 803 are fixedly connected to the outer side of the rotating rod 2 801. The impeller 802 passes through the cleaning pipe 400, and part of the impeller 802 is located inside the cleaning pipe 400. After the casting operation is completed, cleaning fluid is introduced into the removed brass fire butterfly valve through the cleaning pipe 400 for corresponding cleaning operations. The rapidly flowing cleaning fluid drives the impeller 802 to rotate, which in turn drives the rotating rod 2 801 fixedly connected to it to rotate. The rotating rod 2 801 then drives the sprocket 1 803 fixedly connected to it to rotate.

[0029] A chain 804 is mounted on the outer side of sprocket 1 803. A pipe joint 805 is rotatably connected to the bottom of the cleaning pipe 400. A sprocket 2 806 is fixedly connected to the outer side of the pipe joint 805. The end of the chain 804 away from sprocket 1 803 is mounted on the outer side of sprocket 2 806. A nozzle 807 is mounted on the bottom of the pipe joint 805. When sprocket 1 803 rotates, it works in conjunction with the chain 804 mounted on the outer side of sprocket 1 803, causing sprocket 2 806, which is driven by the chain 804, to rotate. Sprocket 2 806 drives the pipe joint 805, which is fixedly connected to it, to rotate. This causes the pipe joint 805 to drive the nozzle 807 mounted on its bottom to rotate, causing the cleaning fluid to rotate and spray onto the brass fire-fighting butterfly valve, increasing the coverage area of ​​the cleaning fluid on the brass fire-fighting butterfly valve, thereby improving the cleaning efficiency of the device.

[0030] In use, based on Embodiment 1 and Embodiment 2, after the casting operation is completed, cleaning fluid is introduced into the removed brass fire-fighting butterfly valve through the cleaning pipe 400 for corresponding cleaning operations. The rapidly flowing cleaning fluid drives the impeller 802 to rotate, which in turn drives the rotating rod 801 fixedly connected to it to rotate. The rotating rod 801 drives the sprocket 803 fixedly connected to it to rotate. In conjunction with the chain 804 mounted on the outside of the sprocket 803, the sprocket 806, which is driven by the chain 804 and the sprocket 803, rotates. The sprocket 806 drives the pipe joint 805 fixedly connected to it to rotate, which in turn drives the nozzle 807 mounted at its bottom to rotate, so that the cleaning fluid is sprayed onto the brass fire-fighting butterfly valve.
