[0007] Further technical solution: A rotating shaft is rotatably installed on the second movable frame, and a support plate is fixedly installed on the rotating shaft. A second rotating power component that drives the rotating shaft to rotate is fixedly installed on the second movable frame. The support plate is arc-shaped and is arranged coaxially with the rotating shaft. A card slot is provided on the support plate. The projection of the card slot to the base is V-shaped, and the card slot is located at the end of the support plate with a larger opening.

[0008] Further technical solution: two groups of guide rods are rotatably installed on the lower surface of the base, the guide rods are slidably connected to the lifting plate, a third telescopic part is provided on the base to drive the guide rods to rotate, two groups of winches are fixedly installed on the base, a pull wire is wound around the winch, and the movable end of the pull wire is fixedly connected to the lifting plate.

[0009] Further technical solution: a second telescopic member is fixedly mounted on the base, a connecting frame is rotatably mounted on the output end of the second telescopic member, and the connecting frame is rotatably connected to the two sets of guide rods.

[0010] Further technical solution: A first protective plate and a second protective plate are fixedly installed on the surface of the lifting plate away from the base, and the second rack is located between the first protective plate and the second protective plate.

[0011] Further technical solution: a turntable is rotatably installed on the base and a fourth telescopic part is rotatably installed on the base to drive the turntable to rotate back and forth. A through groove corresponding to the lower mold is opened in the middle of the turntable and a limiting groove for limiting the position of the lower mold is fixedly installed on the turntable.

[0012] Further technical solution: A baffle is slidably installed on the turntable, the baffle is flush with the upper surface of the turntable and is used to close the through slot on the turntable, a mounting groove is opened on the side of the baffle, a first rack is fixedly installed in the mounting groove, a first rotating power component is fixedly installed on the turntable, and a first gear meshing with the first rack is fixedly installed at the output end of the first rotating power component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The lifting plate drives the breaker rod to move upward, and the breaker rod and the breaker cone can separate the molding sand. The breaker rod can drill multiple groups of rectangular through holes on the molding sand in the upper mold and the lower mold. Due to the existence of the through holes in the molding sand, the connection area between the molding sand wrapped around the casting and the upper mold and the lower mold is reduced, and the restrictive force of the upper mold and the lower mold is reduced. At this time, the first telescopic member drives the cross plate to move upward, so that the support plate can pull the casting out of the mold through the excess metal formed by the pouring port and the riser. There is no need to knock the molding sand in the mold, which avoids damage to the casting and ensures the quality of the casting.

[0015] 2. Before the first telescopic member contracts and pulls out the casting, the second telescopic member is reciprocated to contract and then extend to a set length, while maintaining the rotation of the breaker rod. The second telescopic member drives the guide rod to rotate in two directions by a set angle through the connecting frame. The guide rod drives the lifting plate to rotate and thereby tilt the breaker rod. When the breaker rod is tilted, it can contact with more molding sand and separate the molding sand, thereby further reducing the restriction of the molding sand in the mold on the casting, further reducing the pulling force required to remove the casting, and ensuring that the casting can be removed without damage.

[0016] 3. When the breaker rod completes the drilling of the molding sand and cleans it again, the lifting plate moves downward and resets. At this time, the fourth telescopic member extends or contracts to drive the turntable to rotate, and the turntable drives the lower mold to rotate through the limit groove. The molding sand wrapped around the casting is kept fixed because the support plate is inserted into the molding sand. Therefore, the shear force generated when the lower mold rotates will cause the molding sand between the two groups of through holes to break, thereby disconnecting the molding sand wrapped around the casting from the lower mold and the upper mold. After that, the first telescopic member can take the casting out of the mold, realizing the non-destructive removal of the casting and ensuring the quality of the casting.

The adjusting screw 16 is movable, and the support plate 19 is installed on the second mobile frame 15. The second mobile frame 15 is rotatably installed with a rotating shaft 17. The support plate 19 is fixedly mounted on the rotating shaft 17. The second mobile frame 15 is fixedly installed with a second rotating power member 18 that drives the rotating shaft 17 to rotate. The support plate 19 is arc-shaped and coaxially arranged with the rotating shaft 17. A card slot 20 is provided on the support plate 19. The projection of the card slot 20 to the base 1 is V-shaped, and the card slot 20 is located at the end opening of the support plate 19. The lower surface of the base 1 is provided with a lifting plate 22 that can move up and down. The lower surface of the base 1 is rotatably installed with two sets of guide rods 21. The guide rods 21 and the lifting plate 2 2 sliding connection, a third telescopic member 32 is provided on the base 1 to drive the guide rod 21 to rotate, two sets of hoists 23 are fixedly installed on the base 1, a pull wire 24 is wound around the hoist 23, and the movable end of the pull wire 24 is fixedly connected to the lifting plate 22, a second telescopic member 25 is fixedly installed on the base 1, and a connecting frame 26 is rotatably installed on the output end of the second telescopic member 25, and the connecting frame 26 is rotatably connected to the two sets of guide rods 21. The lifting plate 22 is a circular shape and a plurality of groups of rectangularly distributed crushing rods 27 are rotatably installed on the lifting plate 22. A plurality of groups of spaced-apart crushing cones 28 are fixedly installed on the crushing rods 27. The surface of the lifting plate 22 away from the base 1 is connected by a mounting frame 30 is slidably installed with four groups of second racks 31 distributed in a rectangular pattern on two parallel planes. The rectangle surrounded by the second racks 31 corresponds to the rectangle surrounded by the breaking rod 27. The second racks 31 are engaged with the second gears 29 fixedly installed on the end of the breaking rod 27. A group of second gears 29 located at the corner of the rectangle is engaged with only one group of second racks 31. A third telescopic member 32 is fixedly installed on the lifting plate 22 to drive one group of second racks 31 to move back and forth. A first protective plate 33 and a second protective plate 34 are fixedly installed on the surface of the lifting plate 22 away from the base 1. The second rack 31 is located between the first protective plate 33 and the second protective plate 34.

[0028] In actual application of this embodiment, after the lower mold 9 and the upper mold 10 are prepared, they are placed on the base 1, and then casting is carried out from the pouring port opened on the upper mold 10. After the casting is cooled, the casting is taken out. When taking out the casting, the position of the support plate 19 is adjusted according to the position of the excess metal formed by the pouring port and the riser. After the position of the support plate 19 on the cross plate 13 is adjusted by the first movable frame 14, the position of the first movable frame 14 is fixed by the fixing screw, and then the position of the second movable frame 15 is adjusted by the adjusting screw 16, so that the excess metal formed by the pouring port and the riser is aligned with the position of the card slot 20. After the first telescopic member 12 is aligned, the horizontal plate 13 is driven downward by the first telescopic member 12 to move the support plate 19 close to the upper mold 10. In the initial state, the opening of the support plate 19 faces the upper mold 10. The support plate 19 stops moving after it approaches the molding sand in the upper mold 10. At this time, the support plate 19 is driven to rotate by the second rotating power member 18. Due to the setting of the card slot 20, the end of the support plate 19 is a pointed structure. At this time, the support plate 19 can be inserted into the molding sand. When the support plate 19 contacts the excess metal formed by the pouring port and the riser, it stops rotating. At this time, the position of the casting can be fixed by the support plates 19 on both sides.

[0029] In the initial state, the guide rod 21 is in a vertical state. After the casting position is fixed, the winch 23 is received by the pull wire 24 to drive the lifting plate 22 to move upward, and at the same time, the third telescopic member 32 drives one group of supporting second racks 31 to move back and forth. Since three of the four groups of second gears 29 located at the corners of the rectangle are engaged with the two staggered groups of second racks 31, and the remaining group of second gears 29 is only engaged with one group of second racks 31, so that when one group of second racks 31 moves back and forth, the second gear 29 can drive the other multiple groups of second racks 31 to move back and forth, thereby causing the crushing rod 27 to continue to rotate back and forth. When the crushing rod 27 contacts the molding sand in the lower mold 9, the molding sand can be separated by the crushing rod 27 and the crushing cone 28, and the separated molding sand falls downward. The lifting plate 22 stops moving as the breaker rod 27 rises and penetrates the upper mold 10. The breaker rod 27 can drill a plurality of rectangular through holes in the molding sand inside the upper mold 10 and the lower mold 9. Since the breaker rod 27 is distributed in the area close to the side wall of the lower mold 9, the breaker rod 27 will not contact the internal casting when it moves upward. Due to the presence of the through holes in the molding sand, the connection area between the molding sand wrapped around the casting and the upper mold 10 and the lower mold 9 is reduced, and the restrictive force of the upper mold 10 and the lower mold 9 is reduced. At this time, the first telescopic member 12 drives the cross plate 13 to move upward, so that the support plate 19 can pull the casting out of the mold through the excess metal formed by the pouring port and the riser. There is no need to knock the molding sand in the mold, which avoids damage to the casting and ensures the quality of the casting.

[0030] Before the first telescopic member 12 contracts and pulls out the casting, the second telescopic member 25 is reciprocated to contract and then extend to a set length, while maintaining the rotation of the breaker rod 27. The second telescopic member 25 drives the guide rod 21 to rotate in two directions by a set angle through the connecting frame 26. The guide rod 21 drives the lifting plate 22 to rotate and thereby tilt the breaker rod 27. When the breaker rod 27 is tilted, it can contact with more molding sand and separate the molding sand, thereby further reducing the restriction of the molding sand in the mold on the casting, further reducing the pulling force required to remove the casting, and ensuring that the casting can be removed without damage. After the casting is taken out, the support plate 19 fixing the casting is released, and the sand can be subsequently removed.

[0031] In an example of this embodiment, the second rotating power member 18 is a second motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The support plate 19 is driven to rotate by the second motor, and the first telescopic member 12, the second telescopic member 25, and the third telescopic member 32 are divided into the first, second, and third electric telescopic rods. Of course, they can also be other components that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the horizontal plate 13 to move up and down, the second telescopic member 25 drives the guide rod 21 to rotate, and the third electric telescopic rod drives the breaking rod 27 to rotate.

[0032] like Figure 1 、 Figure 6 As shown, a container corner casting and molding device with anti-damage demoulding function provided by the present invention is provided. A turntable 2 is rotatably installed on the base 1, and a fourth telescopic member 35 that drives the turntable 2 to rotate back and forth is rotatably installed on the base 1. A through groove corresponding to the lower mold 9 is opened in the middle of the turntable 2, and a limiting groove 3 for limiting the position of the lower mold 9 is fixedly installed on the turntable 2.

[0033] Specifically, a baffle 4 is slidably installed on the turntable 2. The baffle 4 is flush with the upper surface of the turntable 2 and is used to close the through slot on the turntable 2. A mounting slot 5 is opened on the side of the baffle 4. A first rack 6 is fixedly installed in the mounting slot 5. A first rotating power component 7 is fixedly installed on the turntable 2. A first gear 8 meshing with the first rack 6 is fixedly installed at the output end of the first rotating power component 7.

[0034] When the present embodiment is actually used, in the initial state, the baffle 4 closes the through-slot on the turntable 2, and the lower mold 9 is placed in the limiting groove 3. The molding sand in the lower mold 9 can be supported by the baffle 4, and the limiting groove 3 is in contact with the outer side of the lower mold 9. When the casting is taken out, the first rotating power member 7 drives the baffle 4 to move outward to open the through-slot on the turntable 2 through the meshing first gear 8 and the first rack 6. At this time, the crushing rod 27 can clean the molding sand upward. When the crushing rod 27 completes the drilling and cleaning of the molding sand again, the lifting plate 22 moves downward to reset. At this time, the fourth telescopic member 35 extends or contracts to drive the turntable 2 to rotate. The turntable 2 drives the lower mold 9 to rotate through the limiting groove 3. The molding sand wrapped around the casting is kept fixed by the support plate 19 inserted into the molding sand. Therefore, the shear force generated when the lower mold 9 rotates will cause the molding sand between the two groups of through holes to break, thereby disconnecting the molding sand wrapped around the casting from the lower mold 9 and the upper mold 10. Then the first telescopic member 12 can take the casting out of the mold, realizing the non-destructive removal of the casting and ensuring the quality of the casting.

[0035] In one embodiment of the present invention, the fourth telescopic member 35 is a fourth electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the turntable 2 is driven to rotate by the fourth electric telescopic rod.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
