[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] This utility model embodiment provides a rapid demolding device for pump body casting, such as... Figure 1-3 As shown, the system includes a fixed base 1 and a demolding mechanism 2. The top of the fixed base 1 is fixed to the demolding mechanism 2. The demolding mechanism 2 uses hydraulic power to lift the upper mold 6 upwards for demolding operations. The top of the fixed base 1 is connected to the demolding seat 4 via a connecting block. The demolding seat 4 can push the mold to a designated position on the demolding seat 4 via a transmission plate 8 and a hydraulic pushing power device. An automatic docking device 7 for fixing the casting mold is connected to the demolding seat 4. The automatic docking device 7 can fix the bottom of the lower mold 5 to facilitate separation from the upper mold 6 for demolding. A lower mold 5 is slidably connected to the top of the base 4. A hanging ear 51 is welded to the side of the lower mold 5. An upper mold 6 is set on the top of the lower mold 5. A demolding ear 61 is welded to the side of the upper mold 6. The demolding ear 61 is used to connect with the demolding mechanism 2 to facilitate the demolding operation of the mold. A transmission plate 8 is set behind the fixed base 1. A guide rail 9 for guiding and conveying the mold is connected to the top of the transmission plate 8. The transmission plate 8 is a smooth plane and its height is flush with the demolding base 4. The guide rail 9 is used to guide the mold during the conveying process and prevent the mold from deviating from the demolding base 4 when it moves.

[0024] like Figure 1-3 As shown, the automatic docking device 7 includes a servo motor 701, a track groove 702, a screw drive rod 703, a drive sliding seat 704, and a docking block 705. The bottom of the demolding seat 4 is fixed to the servo motor 701. Track grooves 702 are provided on both sides of the demolding seat 4. The drive sliding seat 704 is slidably connected inside the track groove 702. The output ends of the two-axis servo motors 701 are respectively fixed with screw drive rods 703. The screw drive rods 703 are threadedly connected to the drive sliding seats 704. After the mold is transported to the designated position of the demolding seat 4, the PLC controller sends a command to drive the two-axis servo motors 701 to rotate. The rotation of the servo motors 701 can drive the screw drive rods 703 to rotate. The rotation of the screw drive rods 703 can drive the drive sliding seats 704 to move closer or further apart. The movement of the two drive sliding seats 704 to move closer together can dock with the demolding seat 4 to fix the lower mold 5 and facilitate subsequent demolding operations.

[0025] The screw drive rod 703 has opposite threads, which can drive the drive slide seat 704 to move closer or further apart.

[0026] The docking block 705 is set at a height higher than the bottom edge of the lower mold 5, so that the docking block 705 can be moved to the edge of the lower mold 5 and the lower mold 5 can be snapped together.

[0027] like Figure 1-2 As shown, the demolding mechanism 2 includes a column 201, a fixed base 202, a hydraulic rod 203, a crossbeam 204, a vertical column 205, a horizontal column 206, a connecting seat 207, and an elastic docking block 208. The top of the fixed base 201 is fixed to the column 201, the side of the column 201 is welded to the fixed base 202, the top of the fixed base 202 is fixed to the hydraulic rod 203, the top of the hydraulic rod 203 is fixed to the crossbeam 204, the end of the crossbeam 204 away from the hydraulic rod 203 is fixed to the vertical column 205, the bottom of the vertical column 205 is welded to the horizontal column 206, the bottom of the horizontal column 206 is fixed to the connecting seat 207, the connecting seat 207 has an inner cavity, a spring is installed inside the inner cavity, and the end of the spring is fixed to the elastic docking block 208. An automatic docking device is also included. 7. After the lower mold 5 is fixed, the PLC controller controls the movement of the hydraulic rod 203. First, the hydraulic rod 203 descends, driving the crossbeam 204, vertical column 205, horizontal column 206, connecting seat 207 and elastic docking block 208 to move downwards. The spring is set so that when the elastic docking block 208 descends and contacts the demolding ear 61, it passes over the demolding ear 61. When it disengages, the elastic docking block 208 automatically pops out and docks with the demolding ear 61. When the position sensor detects that the elastic docking block 208 has moved below the demolding ear 61, the hydraulic rod 203 stops descending and begins to rise. When the hydraulic rod 203 rises, the elastic docking block 208 docks with the demolding ear 61. The lifting of the hydraulic rod 203 quickly disengages the upper mold 6 from the fixed lower mold 5.

[0028] The hydraulic rod 203 is driven by hydraulic control.

[0029] When the elastic docking block 208 is attached to the lower part of the demolding ear 61, it makes contact and docking. The end of the elastic docking block 208 that contacts the demolding ear 61 is convex at an upward angle, which facilitates docking with the cavity of the demolding ear 61.

[0030] Working principle: During use, the un-demolded mold is pushed to a designated position on the demolding seat 4 via the transmission plate 8 and hydraulic pusher. After the mold is delivered to the designated position on the demolding seat 4, the PLC controller sends a command to drive the two-axis servo motor 701 to rotate. The rotation of the servo motor 701 drives the screw drive rod 703 to rotate. The rotation of the screw drive rod 703 drives the drive sliding seats 704 to move closer or further apart. The movement of the two drive sliding seats 704 closer together allows them to dock with the demolding seat 4 to fix the lower mold 5. After the automatic docking device 7 fixes the lower mold 5, the PLC controller controls the movement of the hydraulic rod 203. First... The hydraulic rod 203 descends to drive the crossbeam 204, vertical column 205, horizontal column 206, connecting seat 207, and elastic docking block 208 to move downwards. The spring is designed so that when the elastic docking block 208 descends and contacts the demolding ear 61, it passes over the demolding ear 61. When it disengages, the elastic docking block 208 automatically pops out and docks with the demolding ear 61. When the position sensor detects that the elastic docking block 208 has moved below the demolding ear 61, the hydraulic rod 203 stops descending and begins to rise. When the hydraulic rod 203 rises, the elastic docking block 208 docks with the demolding ear 61. The lifting of the hydraulic rod 203 quickly disengages the upper mold 6 from the fixed lower mold 5.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
