Description

Technical Field

[0001] This invention relates to the field of valve wax molds, and in particular to a mold head welding device for valve wax molds. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid transport systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.

[0003] In valve production, it is necessary to first make a wax mold body, and then weld small mold heads. Currently, the welding of mold heads is done manually by heating metal equipment, which is inefficient and can easily burn the operator.

[0004] Therefore, it is necessary to design an automatic welding device for valve wax mold heads. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that the current welding of mold heads is done manually by heating metal equipment, which is inefficient and can easily burn the operator.

[0006] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a mold head welding device for valve wax molds, the welding device including a plate frame, a welding groove opened on the surface of the plate frame, a conveyor belt provided at the bottom of the plate frame, support plates rotatably connected to both ends of the conveyor belt, a first telescopic pump provided below the conveyor belt, and the support plates connected to the first telescopic pump.

[0007] A rotating rod is rotatably connected to the inner wall of the welding groove. A second telescopic pump is installed inside the rotating rod. A square plate is slidably connected inside the rotating rod. The square plate is located in front of the second telescopic pump. A push rod is connected between the square plate and the second telescopic pump. A support rod is fixedly connected to the front end of the rotating rod. A movable rod is hinged to the front surface of the square plate. The movable rod is hinged to the support rod. A support plate is hinged to the other end of the support rod.

[0008] A support arm is slidably connected to the rear side of the plate frame, and a control block is fixedly connected to the other end of the support arm. A third telescopic pump is fixedly connected to the bottom of the control block, and a fixed head is fixedly connected to the bottom of the third telescopic pump. Two opposing arc grooves are opened on the side wall of the fixed head, and support blocks are slidably connected inside the two arc grooves.

[0009] A tension spring connects the support blocks, and the opposite surfaces of the support blocks are all inclined surfaces. A fourth telescopic pump is installed inside the fixed head. A top rod is fixedly connected to the bottom of the fourth telescopic pump, and a top block is fixedly connected to the other end of the top rod. The bottom of the top block is an inclined surface that matches the opposite surface of the support block.

[0010] The control block has a rotating plate rotatably connected inside. The bottom of the control block has a circular groove. A vertical rod is fixedly connected to the bottom of the rotating plate. The vertical rod passes through the circular groove. A circular block is fixedly connected to the other end of the vertical rod. A welding rod is rotatably connected to the surface of the circular block. A welding head is fixedly connected to the other end of the welding rod. A first motor is provided on the top of the control block. The output end of the first motor is fixedly connected to the rotating plate.

[0011] A ring of circular holes is formed on the surface of the circular block. A slot is formed at the upper end of the welding rod. A plug is inserted into the slot. A button is fixedly connected to the outside of the plug. A spring is fixedly connected between the inside of the button and the welding rod.

[0012] A fan is fixedly connected to the bottom of the plate frame. One end of the fan is connected to an air duct, and the other end of the air duct is fixedly connected to a fan head, which faces the welding groove.

[0013] A second motor is installed on one side of the frame, and the second motor is fixedly connected to the rotating rod.

[0014] The welding head is equipped with a heating wire inside.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. With the conveyor belt in place, in the initial state, the first telescopic pump retracts downward, driving the conveyor belt away from the welding groove, so as not to hinder the welding operation. The mold head is welded in the welding groove. After the welding is completed, the first telescopic pump extends upward, thereby driving the conveyor belt to move upward, catch the welded wax mold, and transport it to the left side of the device for collection.

[0017] 2. By setting up a support plate, the second telescopic pump is controlled to retract, causing the square plate to move inward towards the rotating rod. This causes the movable rod to drive the support plate to retract. Then, one end of the rotating rod with the support plate is inserted into the tail of the wax mold body. After that, the second telescopic pump is controlled to drive the push rod to push the square plate outward. At this time, the movable rod will drive the support plate to open outward, achieving the effect of fixing the wax mold body.

[0018] 3. After the wax mold body is fixed by the top block, the mold head is inserted into the fixed head. When the fourth telescopic pump pushes the top rod downward, the top block will move downward and push the support block outward. The surface of the support block will contact the inner surface of the mold head. The third telescopic pump is started to send the bottom surface of the fixed mold head downward to fit against the wax mold body, in preparation for welding. After welding is completed, the fourth telescopic pump pulls the top rod upward, and the top block moves upward. The tension spring will pull the support block back and release the fixation of the mold head.

[0019] 4. By setting the insertion rod, adjust the position of the welding rod so that the welding head contacts the mold head to be welded. Then start the first motor. The first motor drives the rotating plate to rotate, and the welding rod drives the welding head to rotate accordingly, automatically welding the mold head. The spring always pulls the button towards the welding rod side, so that the insertion rod is inserted into the round hole, fixing the welding rod and the round block. Pull the button outward to disengage the insertion rod, and the position of the welding rod can be adjusted. Attached Figure Description

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0030] Please see Figure 1-8 The welding device includes a plate frame 1, with a welding groove 2 on the surface of the plate frame 1. A conveyor belt 3 is installed at the bottom of the plate frame 1, and support plates 4 are rotatably connected to both ends of the conveyor belt 3. A first telescopic pump 5 is installed below the conveyor belt 3, and the support plates 4 are connected to the first telescopic pump 5. In the initial state, the first telescopic pump 5 retracts downward, driving the conveyor belt 3 away from the welding groove 2 without hindering the welding operation. The mold head performs welding in the welding groove 2. After welding is completed, the first telescopic pump 5 extends upward, thereby driving the conveyor belt 3 to move upward, catch the welded wax mold, and transport it to the left side of the device for collection.

[0031] A rotating rod 6 is rotatably connected to the inner wall of the welding groove 2. A second telescopic pump 7 is installed inside the rotating rod 6. A square plate 8 is slidably connected inside the rotating rod 6. The square plate 8 is located in front of the second telescopic pump 7. A push rod 9 is connected between the square plate 8 and the second telescopic pump 7. A support rod 10 is fixedly connected to the front end of the rotating rod 6. A movable rod 11 is hinged to the front surface of the square plate 8. The movable rod 11 is hinged to the support rod 10. A support piece 12 is hinged to the other end of the support rod 10. The second telescopic pump 7 is controlled to retract, causing the square plate 8 to move into the rotating rod 6. This causes the movable rod 11 to drive the support piece 12 to retract. Then, one end of the rotating rod 6 with the support piece 12 is inserted into the tail of the wax mold body. After that, the second telescopic pump 7 is controlled to drive the push rod 9 to push the square plate 8 outward. At this time, the movable rod 11 will drive the support piece 12 to open outward, achieving the effect of fixing the wax mold body.

[0032] A support arm 13 is slidably connected to the rear side of the plate frame 1. A control block 14 is fixedly connected to the other end of the support arm 13. A third telescopic pump 15 is fixedly connected to the bottom of the control block 14. A fixed head 16 is fixedly connected to the bottom of the third telescopic pump 15. Two opposing arc grooves are opened on the side wall of the fixed head 16. Support blocks 17 are slidably connected inside the two arc grooves. After the wax mold body is fixed, the mold head is inserted into the fixed head 16. When the two support blocks 17 are pushed outward, the surface of the support blocks 17 will contact the inner surface of the mold head, thereby fixing the mold head. Then, the third telescopic pump 15 is started to send the fixed mold head downward to fit against the wax mold body, in preparation for welding.

[0033] A tension spring 18 connects the support blocks 17. The opposing surfaces of the support blocks 17 are all inclined. A fourth telescopic pump 19 is installed inside the fixed head 16. A push rod 20 is fixedly connected to the bottom of the fourth telescopic pump 19. A top block 21 is fixedly connected to the other end of the push rod 20. The bottom of the top block 21 is an inclined surface that matches the opposing surface of the support block 17. When the fourth telescopic pump 19 pushes the push rod 20 downward, the top block 21 will push the support block 17 outward to fix the mold head. After welding is completed, the fourth telescopic pump 19 pulls the push rod 20 upward, and the top block 21 moves upward. The tension spring 18 will pull the support block 17 back to release the fixation of the mold head.

[0034] A rotating plate 22 is rotatably connected inside the control block 14. A circular groove 23 is provided at the bottom of the control block 14. A vertical rod 24 is fixedly connected to the bottom of the rotating plate 22. The vertical rod 24 passes through the circular groove 23. A circular block 25 is fixedly connected to the other end of the vertical rod 24. A welding rod 26 is rotatably connected to the surface of the circular block 25.

The output end of the first motor 28 is fixedly connected to the rotating plate 22. After the welding rod 26 is adjusted to a position so that the welding head 27 contacts the mold head to be welded, the first motor 28 is started. The first motor 28 drives the rotating plate 22 to rotate, thereby the welding rod 26 drives the welding head 27 to rotate, and the mold head is automatically welded.

[0035] A circular hole 29 is formed on the surface of the circular block 25. A slot is formed at the upper end of the welding rod 26. A rod 30 is inserted into the slot. A button 31 is fixedly connected to the outside of the rod 30. A spring 32 is fixedly connected between the inside of the button 31 and the welding rod 26. The spring 32 always pulls the button 31 toward the welding rod 26, so that the rod 30 is inserted into the circular hole 29, thus fixing the welding rod 26 and the circular block 25. Pulling the button 31 outwards disengages the rod 30, allowing the position of the welding rod 26 to be adjusted.

[0036] A fan 33 is fixedly connected to the bottom of the frame 1. One end of the fan 33 is connected to an air duct 34, and the other end of the air duct 34 is fixedly connected to a blower head 35, which faces the welding tank 2. When the fan 33 is started, the fan 33 sends air from the air duct 34 to the blower head 35, which sprays air onto the welding tank 2 to dry the welded wax model.

[0037] A second motor 36 is provided on one side of the plate frame 1. The second motor 36 is fixedly connected to the rotating rod 6. The second motor 36 can control the rotation of the rotating rod 6, so that the rotating rod 6 drives the wax mold body to change its surface.

[0038] The welding head 27 is equipped with an electric heating wire inside; the electric heating wire heats the welding head 27 after being energized, and then welds the mold head.
