[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] Traditional high-quality valve castings need to be manually removed from the casting mold after casting. It is difficult to quickly remove the formed valve from the casting mold, which seriously affects the production efficiency of the mold and makes the casting device for high-quality valve castings very inconvenient to use. Therefore, a high-quality valve casting casting device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 A high-quality valve casting casting device in this embodiment includes a base plate 1, a support plate 2 is fixed on the top of the base plate 1, a lower mold 3 is fixed on the top of the support plate 2, and a pushing component is slidably connected inside the support plate 2, and the pushing component is used to push the casting to move.

[0023] In addition, two linkage components 7 are fixed to the top of the pushing component, and the linkage components 7 are used to drive the pushing component to move. Two limit blocks 8 are fixed to the bottom of the support plate 2, and the limit blocks 8 are used to push the plug-in block 702 to move. A linkage rod 9 is fixed to the inside of the linkage component 7 and passes through the top of the support plate 2. An upper mold 10 is fixed to the top of the two linkage rods 9, and a driving component is fixed to the top of the upper mold 10. A sealing block is fixed to the bottom of the upper mold 10, and a sealing groove matched with the sealing block is opened on the top of the lower mold 3. The sealing block and the sealing groove can effectively improve the sealing of the connection between the lower mold 3 and the upper mold 10, thereby making the whole more stable.

[0024] Furthermore, the pushing assembly includes a pushing plate 4 slidably connected to the supporting plate 2, sliding blocks are fixed on the front and rear sides of the pushing plate 4, a sliding groove slidably connected to the sliding block is provided inside the supporting plate 2, and the sliding connection between the sliding block and the sliding groove makes the movement of the pushing plate 4 more stable, a pushing rod 5 penetrating into the lower mold 3 is fixed on the top of the pushing plate 4, a pushing block 6 is fixed on the top of the pushing rod 5, and a driving assembly is used to drive the upper mold 10 to move, and the driving assembly includes a cylinder 11 fixed to the telescopic end of the upper mold 10, and the telescopic end of the cylinder 11 faces downward. Through the set cylinder 11, the upper mold 10 can be pushed to close the mold with the lower mold 3, and a casting pipe is fixed to the right side of the lower mold 3, a fixed plate 12 is fixed to the outer surface of the cylinder 11, and a fixed rod 13 fixed to the bottom of the fixed plate 12 is fixed to the bottom of the fixed plate 12.

[0025] In general, the cylinder 11 is provided to push the upper mold 10 and the lower mold 3 to close the mold, and the linkage rod 9 can move together with the upper mold 10, so as to facilitate the subsequent removal of the casting.

[0026] See also Figure 2-3In order to facilitate the removal of the casting, the linkage assembly 7 in this embodiment includes a fixed block 701, a plug-in block 702, a support block 703 and a reset spring 704. The fixed block 701 is fixed to the top of the pushing assembly, the plug-in block 702 is slidably connected to the fixed block 701, and the plug-in block 702 is plugged into the linkage rod 9. The upper and lower sides of the plug-in block 702 are provided with inclined surfaces on the side opposite to the two limit blocks 8. The length of the top inclined surface of the plug-in block 702 is greater than the length of the bottom inclined surface of the plug-in block 702. When the plug-in block 702 is plugged into the linkage rod 9, the top inclined surface is entirely located inside the linkage rod 9, and only a portion of the bottom inclined surface is located inside the linkage rod 9, so that when the linkage rod 9 moves upward, the linkage rod 9 will push the bottom of the plug-in block 702 to pull the fixed block 701 to move upward.

[0027] In addition, the opposite sides of the two plug-in blocks 702 are fixed to the support block 703, a sponge pad is fixed to the inner bottom wall of the fixed block 701, a friction strip is fixed to the outer surface of the support block 703, and the opposite sides of the two support blocks 703 are fixed to the reset spring 704, and the reset spring 704 is fixed to the fixed block 701. The set reset spring 704 can accumulate elastic potential energy, so that the plug-in block 702 can be reset.

[0028] In general, when the linkage rod 9 pulls the fixed block 701 to move upward, the plug-in block 702 will come into contact with the limit block 8, thereby squeezing the plug-in block 702 to move, so that the inclined surface of the plug-in block 702 can be completely located inside the linkage rod 9, so that the linkage rod 9 can squeeze the inclined surface, so that the linkage rod 9 and the plug-in block 702 are separated.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] When the cylinder 11 pushes the upper mold 10 and the lower mold 3 to close the mold, the linkage rod 9 will move downward, so that the linkage rod 9 moves downward and is inserted into the interior of the fixed block 701 and contacts the inclined surface at the top of the plug-in block 702, thereby squeezing the plug-in block 702, so that the plug-in block 702 moves to the outside of the fixed block 701, and the reset spring 704 accumulates elastic potential energy. When the linkage rod 9 is completely inserted into the interior of the fixed block 701, the elastic potential energy accumulated by the reset spring 704 will reset the plug-in block 702, so that the plug-in block 702 is inserted into the interior of the linkage rod 9 to fix the linkage rod 9. After the casting is formed, when the cylinder 11 pulls the linkage rod 9 to move upward, the plug-in block 702 is pressed. The inclined surface at the bottom of 02 is not completely located inside the linkage rod 9, which will pull the fixed block 701, the push plate 4, the push rod 5 and the push block 6 to move upward together and thus eject the casting. When the plug-in block 702 moves to fit with the limit block 8, the inclined surface of the limit block 8 will squeeze the plug-in block 702, thereby moving the plug-in block 702, so that the inclined surface at the bottom of the plug-in block 702 is completely located inside the linkage rod 9. At this time, when the linkage rod 9 moves upward, it will squeeze the inclined surface at the bottom of the plug-in block 702, so that the linkage rod 9 and the plug-in block 702 lose connection and are separated from the fixed block 701. The overall structure is simple, which effectively improves the efficiency of casting removal, making the overall structure more practical.
