[0014] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 4 As shown: A temperature control valve core powder pressing device includes a base 1 and an extrusion module. The extrusion module is installed on the base 1. The device also includes a forming component, which is installed on the base 1 and located directly below the extrusion module. This allows the extrusion module to press the valve core powder into the forming component. The forming component includes a cutting module, a pressing module, and a lifting module. The extrusion module can press the valve core powder into the cutting module, and the cutting module can cut the extruded valve core powder, leaving a fixed amount of valve core powder at the cutting module. The pressing module is located above the cutting module, and the lifting module is located below the cutting module. The pressing module and the lifting module are adapted to each other and work together to press the fixed amount of valve core powder cut at the cutting module into the valve core copper sleeve. The cutting module includes a pusher cylinder 17 and a forming mold. The pusher cylinder 17 is connected to the forming mold and is used to push and pull the forming mold. The forming mold includes a support frame 6, an upper template 7, a lower template 8, and a cutting plate 18. The support frame 6 is fixedly installed on the base 1. The upper template 7 and the lower template 8 are fixedly installed on the support frame 6. The cutting plate 18 is slidably disposed between the upper template 7 and the lower template 8. The upper template 7 and the lower template 8 are used to block the upper and lower sides of the cutting plate 18, respectively. The cutting plate 18 is fixedly connected to the piston rod of the pusher cylinder 17, and the pusher cylinder 17 is fixedly installed on the base 1. The top and bottom walls of the cutting plate 18 are respectively connected to the upper template 7 and the lower template 8. 8. The upper template 7 is fixedly connected to the extrusion module. The upper template 7 is provided with a feeding hole, and the cutting plate 18 is provided with a forming hole 19. The extrusion module can squeeze the valve core powder into the forming hole 19 through the feeding hole. The lower template 8 is provided with a detection hole. The valve core material in the forming hole 19 can enter the detection hole. The detection hole has a bucket-shaped structure with a larger top and a smaller bottom, which reduces the passage of powder and makes the powder in the detection hole only able to emerge from it under a certain pressure. When the pushing cylinder 17 pushes the cutting plate 18 to move, when the forming hole 19 is misaligned with the feeding hole and the detection hole, the valve core powder between the three can be cut off, so that a certain amount of valve core powder remains in the forming hole 19. The lower template 8 has a discharge hole at the end away from the pusher cylinder 17. The pressing module and the lifting module are directly above and below the discharge hole, respectively. When the forming hole 19 of the cutting plate 18 moves above the discharge hole, the pressing module can press the valve core powder in the forming hole 19 into the valve core copper sleeve at the lifting module through the discharge hole. The lifting module includes a lifting cylinder 15 and a fixture 16. The lifting cylinder 15 is fixedly installed on the base 1. The fixture 16 is provided at the end of the piston rod of the lifting cylinder 15. The lifting cylinder 15 is used to lift the fixture 16. The fixture 16 is used to install the valve core copper sleeve. The fixture 16 is adapted to the discharge hole so that the valve core copper sleeve on the fixture 16 can be connected to the discharge hole. The pressing module includes a pressing cylinder 11 and an ejector pin 13. The pressing cylinder 11 is fixedly installed at the upper template 7. The piston rod end of the pressing cylinder 11 is provided with an ejector pin 13 that is adapted to the discharge hole. The pressing cylinder 11 is used to drive the ejector pin 13 to press the valve core powder in the forming hole 19 into the valve core copper sleeve.

[0015] The bottom of the lower template 8 is equipped with a photoelectric sensor for detecting material discharge from the detection hole. The photoelectric sensor is used to detect whether material is being discharged from the detection hole and to determine whether the forming hole 19 is filled with valve core powder.

[0016] The extrusion module includes a fixed frame 2, an extrusion motor 3, an extrusion screw 4, a hopper 5, and an extrusion sleeve 25. The extrusion motor 3 and the hopper 5 are both fixedly installed on the base 1 through the fixed frame 2, with the extrusion motor 3 located directly above the hopper 5. The extrusion sleeve 25 is installed at the bottom of the hopper 5 and is fixedly installed on the upper template 7. The extrusion sleeve 25 is adapted to the feed hole at the upper template 7. The output shaft of the extrusion motor 3 is equipped with the extrusion screw 4, which extends through the hopper 5 into the extrusion sleeve 25. When the extrusion motor 3 drives the extrusion screw 4 to rotate, it can extrude the valve core powder in the hopper 5 through the extrusion sleeve 25 into the feed hole of the upper template 7, thereby allowing the valve core powder to enter the forming hole 19 of the cutting plate 18. The valve core powder can then be initially pressed into a cylindrical structure in the forming hole 19.

[0017] A guide sleeve 9 is installed in the discharge hole. When the lifting module lifts the valve core copper sleeve, the bottom of the guide sleeve 9 is inserted into the valve core sleeve, so that the valve core powder in the forming hole 19 can be pressed into the valve core copper sleeve more accurately.

[0018] The pressing module is equipped with a first positioning mechanism, which includes a mounting plate 12 and a first positioning rod 14. The mounting plate 12 is fixedly installed at the end of the piston rod of the pressing cylinder 11, and the first positioning rod 14 is fixedly installed at the bottom of the mounting plate 12. The length of the first positioning rod 14 is greater than the length of the ejector pin 13. The first positioning rod 14 is adapted to the first positioning hole 20 opened at the cutting plate 18, so that the pressing cylinder 11 can simultaneously drive the ejector pin 13 and each of the first positioning rods 14 to press down. The first positioning rod 14 can be inserted into the first positioning hole 20 first to position the cutting plate 18. Then the first positioning rod 14 is inserted into the lower template 8, so that the forming hole 19 and the guide sleeve 9 are accurately positioned, and the ejector pin 13 is inserted into the guide sleeve 9 more accurately.

[0019] A second positioning mechanism is installed at the upper template 7. The second positioning mechanism includes a positioning cylinder 22, a connecting plate 23, and several second positioning plates. The positioning cylinder 22 is fixedly installed on one end of the upper template 7 near the pushing cylinder 17. A connecting plate 23 is installed at the piston rod of the positioning cylinder 22. Several second positioning rods 24 are installed at the bottom of the connecting plate 23. The second positioning rods 24 are adapted to the second positioning holes 21 set at the cutting plate 18. The positioning cylinder 22 can drive the second positioning rods to press down, so that the second positioning rods 24 can be inserted into the second positioning holes 21 of the upper template 7, the cutting plate 18, and the lower template 8 in sequence, so that the feeding hole, the forming hole 19, and the detection hole are accurately positioned.

[0020] A limiting block 10 is installed at the end of the lower template 8 away from the pushing cylinder 17. The limiting block 10 is used to position the cutting plate 18 and the lower template 8.

[0021] The specific implementation process is as follows: When using this temperature control valve core powder pressing device, the pushing cylinder 17 drives the cutting plate 18 to retract, aligning the feeding hole at the upper template 7 with the forming hole 19 of the cutting plate 18 and the detection hole of the lower template 8. The positioning cylinder 22 drives each of the second positioning rods 24 to press down. The second positioning rods 24 pass through the upper template 7, the second positioning hole 21 of the cutting plate 18, and the lower template 8 in sequence, thus accurately positioning the upper template 7, the cutting plate 18, and the lower template 8. Then, the extrusion motor 3 starts, driving the extrusion screw 4 to rotate. The extrusion screw 4 squeezes the valve core powder in the hopper 5 through the extrusion sleeve 25 into the feeding hole, the forming hole 19, and the detection hole. The extrusion screw 4 continues to squeeze, causing the valve core powder to emerge from the bottom of the detection hole. After the photoelectric sensor detects the valve core powder emerging, it sends a signal to the corresponding controller. The controller controls the piston rod of the positioning cylinder 22 to retract, aligning the second positioning rod 24 with the second positioning hole. 21 separates, releasing the cutting plate 18, while the extrusion motor 3 stops. Then, the pushing cylinder 17 pushes the cutting plate 18, causing the feed hole, forming hole 19, and detection hole to misalign. The forming plate then cuts the valve core powder, leaving a quantitative amount of valve core powder in the forming hole 19, until the cutting plate 18 is pressed against the limit block 10. The lifting cylinder 15 then lifts the fixture 16 containing the valve core copper sleeve, connecting the valve core copper sleeve with the guide sleeve 9. Then, the pressing cylinder 1... The piston rod of 1 extends, pressing down the first positioning rod 14 and the ejector pin 13. The first positioning rod 14 is inserted into the first positioning hole 20 and the lower template 8 at the cutting plate 18. Then the ejector pin 13 is inserted into the forming cavity of the cutting plate 18, and the valve core and valve diaphragm in the forming cavity are pressed into the valve core copper sleeve through the guide sleeve 9, thus completing the pressing of the valve core powder. Finally, the pressing module, the lifting module and the module are reset in sequence, ready to perform the next work of pressing the valve core copper sleeve into powder.

[0022] This temperature control valve core powder pressing device uses an extrusion module to squeeze valve core powder into the forming hole 19 of the cutting plate 18. Driven by a pushing cylinder, the cutting plate 18, in conjunction with the upper template 7 and lower template 8, cuts the material, leaving an appropriate amount of valve core powder in the forming hole. The cutting plate 18 is then pushed between the pressing module and the lifting module, allowing the pressing module to press the valve core material from the forming hole 19 into the valve core copper shell placed at the lifting module. This completes the quantitative pressing of the valve core powder, effectively improving the accuracy of valve core powder usage and increasing valve core production efficiency.
