Description

Technical Field

[0001] This utility model relates to the field of pressure casting mold technology, and in particular to a pressure casting mold for processing copper valves. Background Technology

[0002] In the field of copper valve manufacturing, pressure casting is a key forming process. It uses high pressure to rapidly inject molten metal into a mold cavity to obtain high-precision, high-quality copper valve castings. The pressure casting mold, as the core component of this process, directly affects the production efficiency, quality, and cost of copper valves.

[0003] Currently, there are many inconveniences in the installation and disassembly of pressure casting molds for copper valve processing. Traditional installation methods often rely on bolt fastening structures, requiring operators to spend a lot of time tightening and loosening the bolts, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pressure casting mold for copper valve processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressure casting mold for processing copper valves includes a base plate. Four sliding rods are fixedly installed on the top of the base plate. The top of the four sliding rods is fixedly installed on the same top plate. A hydraulic cylinder is fixedly installed on the bottom of the top plate. A lifting plate is fixedly installed on the telescopic end of the hydraulic cylinder. All four sliding rods pass through the lifting plate and are slidably connected to it. An upper mold is provided at the bottom of the lifting plate, and a lower mold is provided at the top of the base plate. Two "T"-shaped grooves are provided at the bottom of the lifting plate and the top of the base plate. Two "T"-shaped sliders are fixedly installed at the bottom of the upper mold and the top of the lower mold. Insertion holes are provided on the outer walls of both sides of the upper mold and the lower mold. Two mounting boxes are fixedly installed at the bottom of the lifting plate and the top of the base plate. Limiting components are provided in all four mounting boxes.

[0007] Preferably, the limiting component includes a threaded rod that passes through and is threadedly connected to one side of the outer wall of the mounting box. A stop block is rotatably connected to one end of the threaded rod inside the mounting box, and a knob is fixedly installed at the other end of the threaded rod outside the mounting box. Two circular holes are formed on one end of the inner wall of the mounting box, and an insertion rod is provided in each of the two circular holes. A common movable block is fixedly installed at the end of the two insertion rods near the stop block. A spring is fixedly connected between the movable block and the inner wall of the mounting box at the end with the circular holes. A guide rod is fixedly installed between the two inner walls of the mounting box, and the stop block is slidably fitted onto the guide rod.

[0008] Preferably, the "T"-shaped slider is adapted to the "T"-shaped groove.

[0009] Preferably, positioning blocks are fixedly installed at the bottom of the lifting plate and the top of the base plate.

[0010] Preferably, the vertical cross-sections of both the abutment block and the movable block are right-angled trapezoidal shapes.

[0011] Preferably, the insertion hole and the circular hole have the same diameter.

[0012] The beneficial effects of this utility model are:

[0013] By setting a limit component, the upper and lower molds can be positioned accurately by cooperating with the "T"-shaped slider and the "T"-shaped groove and the positioning block. By rotating the knob, the threaded rod is rotated, which drives the abutment block to move. The inclined plane is used to move the moving block, which in turn allows the insertion rod to be inserted into the insertion hole to complete the installation and fixation. When disassembling, the spring force is used to remove the insertion rod from the insertion hole, which improves work efficiency and reduces the difficulty of operation. Attached Figure Description

Detailed Implementation

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

[0019] Reference Figures 1-3A pressure casting mold for processing copper valves includes a base plate 10. Four sliding rods 6 are fixedly installed on the top of the base plate 10. A top plate 1 is fixedly installed on the top of the four sliding rods 6. A hydraulic cylinder 2 is fixedly installed on the bottom of the top plate 1. A lifting plate 4 is fixedly installed on the telescopic end of the hydraulic cylinder 2. All four sliding rods 6 pass through and are slidably connected to the lifting plate 4. An upper mold 7 is provided at the bottom of the lifting plate 4, and a lower mold 11 is provided at the top of the base plate 10. Two "T"-shaped grooves 5 are provided at the bottom of the lifting plate 4 and the top of the base plate 10. Two... Each "T"-shaped slider 13 has insertion holes 15 on both outer walls of the upper mold 7 and the lower mold 11. Two mounting boxes 9 are fixedly installed on the bottom of the lifting plate 4 and the top of the base plate 10. Limiting components are provided in all four mounting boxes 9. The "T"-shaped slider 13 is adapted to the "T"-shaped slide groove 5. Positioning blocks 8 are fixedly installed on the bottom of the lifting plate 4 and the top of the base plate 10. The positioning blocks 8 provide a reference for the installation of the upper mold 7 and the lower mold 11. When the upper mold 7 and the lower mold 11 abut against the two positioning blocks 8 respectively, it indicates that the insertion hole 15 on the upper mold 7 or the lower mold 11 is aligned with the round hole 17 on the mounting box 9.

[0020] The limiting component includes a threaded rod 12 that passes through and is threadedly connected to the outer wall of one side of the mounting box 9. One end of the threaded rod 12 inside the mounting box 9 is rotatably connected to a stop block 20, and the other end of the threaded rod 12 outside the mounting box 9 is fixedly mounted with a knob 14. Two round holes 17 are opened on the inner wall of one end of the mounting box 9. An insertion rod 16 is provided in each of the two round holes 17. The same moving block 19 is fixedly mounted on the end of the two insertion rods 16 near the stop block 20. A spring 18 is fixedly connected between the moving block 19 and the inner wall of the end of the mounting box 9 with the round hole 17. A guide rod 3 is fixedly mounted between the inner walls of both sides of the mounting box 9. The stop block 20 is slidably fitted on the guide rod 3. The vertical cross-section of both the stop block 20 and the moving block 19 is a right trapezoid. The stop block 20 moves under the drive of the threaded rod 12, and its inclined surface cooperates with the inclined surface of the moving block 19 to achieve the pushing action on the moving block 19. The diameter of the insertion hole 15 and the round hole 17 are the same.

[0021] In use, the two "T"-shaped sliders 13 on the upper mold 7 are respectively located in the two "T"-shaped grooves 5 on the lifting plate 4, and the two "T"-shaped sliders 13 on the lower mold 11 are respectively located in the two "T"-shaped grooves 5 on the base plate 10. The upper mold 7 and lower mold 11 are respectively abutted against the two positioning blocks 8. When the upper mold 7 and lower mold 11 abut against the two positioning blocks 8, the insertion holes 15 on the upper mold 7 and lower mold 11 are aligned with the round holes 17 on the mounting box 9. At this time, the threaded rod 12 is rotated by turning the knob 14. Because the threaded rod 12 is rotatably connected to the abutment block 20 and... The guide rod 3 is set to guide the block 20 so that it does not rotate, and thus the block 20 can move. When the block 20 moves, the inclined surface on the block 20 cooperates with the inclined surface on the moving block 19, so that the moving block 19 can move towards the upper mold 7 or the lower mold 11. The spring 18 is compressed, and the insertion rod 16 is inserted into the insertion hole 15 through the round hole 17, thus realizing the installation and fixation of the upper mold 7 or the lower mold 11. Conversely, the elastic force generated by the compression of the spring 18 can make the insertion rod 16 move away from the insertion hole 15, thus realizing the disassembly of the upper mold 7 or the lower mold 11.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
