[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an automatic part-removing mechanism for a gravity casting machine, including a mounting frame 1, a receiving tray 101 and a mounting plate 2. The receiving tray 101 is provided inside the mounting frame 1, and the mounting plate 2 is provided on the side of the mounting frame 1 away from the receiving tray 101. A lifting cylinder 202 is connected to the middle of the mounting plate 2, and a movable seat 201 is connected to the bottom of the mounting plate 2. A connecting plate 3 is connected to the bottom of the lifting cylinder 202, and a guide rod 203 is connected to the upper side of the connecting plate 3. The outer side of the guide rod 203 is inserted into the movable seat 201. A sliding groove 301 is provided inside the connecting plate 3, and the sliding groove 301 is slidably connected to a sliding frame 302. One end of a pushing cylinder 303 is connected inside the sliding frame 302, and the other end of the pushing cylinder 303 is connected to the connecting plate 3. A sliding rail 304 is connected to the bottom of the sliding frame 302, and the outer side of the sliding rail 304 is slidably connected to a sliding block 305. The bottom of the sliding block 305 is connected to a clamping claw 4.

[0025] An adjusting gear 401 is provided on the upper side of the clamping claw 4, and one side of the adjusting gear 401 is connected to the sliding block 305. An adjusting cylinder 402 is provided on the upper side of the adjusting gear 401, and one side of the adjusting cylinder 402 is connected to the sliding block 305. The bottom of the adjusting cylinder 402 is connected to the adjusting gear 401 on the adjacent side. A transmission gear 403 is provided on one side of the adjusting gear 401, and the adjacent sides of the two adjusting gears 401 are engaged with the transmission gear 403. The upper sides of the slide groove 301 and the sliding frame 302 are both "T" shaped. The adjusting gear 401 is symmetrically arranged on both sides of the transmission gear 403. There are four sets of sliding blocks 305, and the four sets of sliding blocks 305 are symmetrically arranged at the sliding track 304. The clamping claws 4 are symmetrically arranged at the bottom of the sliding frame 302, and the upper sides of the two clamping claws 4 are symmetrically connected with sliding blocks 305.

[0026] In specific implementation, to facilitate the automatic gripping of workpieces by the casting machine, the pushing cylinder 303 installed inside the connecting plate 3 is activated, pushing the sliding frame 302 in the slide groove 301 to move to a suitable gripping position. The adjusting cylinder 402 inside the sliding frame 302 is then activated, pushing the adjusting gear 401 connected to it to move. This, in turn, through the meshing action of the adjusting gear 401 and the transmission gear 403, moves the adjusting gear 401 on the side away from the adjusting cylinder 402. This causes the symmetrically arranged clamping claws 4 at the bottom of the sliding frame 302 and the symmetrically connected sliding blocks 305 on the upper side of the sliding frame 302 to be pushed and unfolded along the sliding track 304. Then, the mounting plate 2 and... The lifting cylinder 202 installed at the movable seat 201 pushes the connecting plate 3, sliding frame 302 and clamping claw 4 downward until the clamping claw 4 is located on both sides of the workpiece. Then, the adjusting cylinder 402 is activated again to repeat the above-mentioned meshing operation of the adjusting gear 401 and the transmission gear 403, which drives the two clamping claws 4 to move closer to each other and clamp the workpiece. The lifting cylinder 202 is activated again to drive the connecting plate 3 to reset, thus realizing the automatic gripping of the workpiece. The automatic part removal mechanism of this gravity casting machine continuously adjusts the position of the clamping claw 4 through the cooperation of multiple components, which can realize the stable gripping of the workpiece, thereby realizing the initial automatic part removal of the workpiece and improving the part removal efficiency.

[0027] See Figure 1 , Figure 5 and Figure 6 It is known that a drive motor 5 is installed on one side of the movable seat 201. The output end of the drive motor 5 is connected to the drive gear 501 through a coupling. The outer side of the drive gear 501 meshes with the linear gear 502. The bottom of the linear gear 502 is connected to the mounting frame 1. The upper side of the mounting frame 1 is symmetrically connected with linear guide rails 503. The outer sides of the two linear guide rails 503 are slidably connected with guide seats 504. The tops of the two guide seats 504 are connected to the movable seat 201. The bottom of the receiving tray 101 is symmetrically connected with a movable plate 6. One side of the movable plate 6 is inserted into the movable track 601. The movable track 601 is equipped with a push cylinder 602. One side of the movable track 601 is connected to the mounting frame 1. One end of the push cylinder 602 is connected to the movable plate 6 on the adjacent side.

[0028] In specific implementation, to facilitate the transport of workpieces, the drive motor 5 installed on one side of the movable seat 201 is started. The output end of the drive motor 5 drives the drive gear 501 to rotate through the coupling. When the drive gear 501 rotates, it meshes with the linear toothed rail 502 on one side, thereby driving the movable seat 201 and the guide seat 504 at the bottom of the movable seat 201 to move along the linear guide rail 503 to the upper side of the receiving tray 101. At this time, the push cylinder 602 inside the movable rail 601 connected to the mounting frame 1 is started. The push cylinder 602 pushes the movable plate 6 connected to it to move along the groove inside the movable rail 601, which can push the receiving tray 101 connected to the movable plate 6 to move to the appropriate receiving position for receiving. The automatic part-retrieving mechanism of this gravity casting machine can smoothly transport the automatically retrieved workpiece to the appropriate position of the receiving tray 101 for placement, which facilitates the subsequent processing of the workpiece and reduces the labor intensity of the workers.

[0029] In summary, when using the automatic part-retrieving mechanism of this gravity casting machine, the push cylinder 303 and the adjusting cylinder 402 are activated to adjust the gripping positions of the sliding frame 302 and the clamping claw 4. The lifting cylinder 202 is activated until the clamping claw 4 is located on both sides of the workpiece. Then, the adjusting cylinder 402 and the lifting cylinder 202 are activated again to complete the automatic gripping of the workpiece. The drive motor 5 is activated, and through the meshing of the drive gear 501 and the linear toothed rail 502, the moving seat 201 and the guide seat 504 are moved along the linear guide rail 503 to the upper side of the receiving tray 101. The push cylinder 602 is activated, and the push cylinder 602 pushes the moving plate 6 to move along the groove inside the moving rail 601, which pushes the receiving tray 101 connected to the moving plate 6 to the appropriate receiving position for receiving materials.
