DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-3 , a casting part casting demolding device includes a bottom plate 1. A buffer pad 17 is fixedly connected to the upper end of the bottom plate 1, which is used for buffering and protecting the cast parts that fall off during demolding to prevent them from being damaged.

[0022] Two first plates 2 are fixedly connected to the upper end of the bottom plate 1. A sliding plate 3 is slidably connected to the side wall of the first plate 2. The side walls of the two sliding plates 3 that are close to each other are fixedly connected with a placing ring 4. An inverted casting mold 6 is arranged on the placing ring 4. The side wall of the first plate 2 is elastically connected to the side wall of the placing ring 4 through a plurality of springs 5.

[0023] The knocking mechanism includes an L-shaped plate 7 fixedly connected to the upper end of the base plate 1, two hydraulic cylinders 8 are fixedly connected to the upper end of the L-shaped plate 7, the movable ends of the two hydraulic cylinders 8 are fixedly connected to a fixed plate 9, and a plurality of knocking rods 10 are fixedly connected to the lower end of the fixed plate 9.

[0024] The intermittent extension and retraction of the movable shafts of the two hydraulic cylinders 8 can drive the fixed plate 9 and the plurality of knocking rods 10 to move up and down intermittently, and intermittently knock the casting mold 6 without manual knocking, thereby reducing the labor intensity of manual operation.

[0025] The moving mechanism is used to drive the casting mold 6 to move back and forth during the knocking process. The moving mechanism includes a vertical rod 11 rotatably connected to the upper end of the base plate 1, and the side wall of the vertical rod 11 is fixedly connected to an incomplete gear 12. The side wall of the placement ring 4 is fixedly connected to a toothed plate 13, and the incomplete gear 12 meshes with the toothed plate 13 during rotation.

[0026] The upper end of the vertical rod 11 is fixedly connected to a rifle rod 14, the side wall of the rifle rod 14 is threadedly connected to a threaded sleeve 15, the side wall of the threaded sleeve 15 is fixedly connected to a connecting plate 16, and the side wall of the connecting plate 16 is fixedly connected to the side wall of the movable shaft of one of the hydraulic cylinders 8.

[0027] During the intermittent extension and retraction of the movable shaft of the hydraulic cylinder 8, the threaded sleeve 15 will be driven to move up and down on the side wall of the rifle rod 14 through the connecting plate 16, thereby driving the rifle rod 14 to rotate intermittently forward and backward. At this time, the vertical rod 11 will drive the incomplete gear 12 to rotate intermittently forward and backward. When the incomplete gear 12 rotates and engages with the tooth plate 13, the tooth plate 13 will drive the placement ring 4 to move, and drive the casting mold 6 to move. At this time, the springs 5 ​​on both sides of the placement ring 4 will be driven to contract and extend respectively. When the incomplete gear 12 rotates and separates from the tooth plate 13, under the elastic force of multiple springs 5, the placement ring 4 will be driven to move to its original position, and then during the intermittent extension and retraction of the hydraulic cylinder 8, the placement ring 4 will drive the casting mold 6 to move back and forth, thereby accelerating the demolding of the cast parts, avoiding the need to manually lift and shake the casting mold in the prior art, thereby accelerating the demolding efficiency, thereby cooperating with automatic knocking to improve the demolding efficiency.

[0028] When demoulding the cast part, first place the casting mold 6 upside down on the placement ring 4 (such as Figure 2 As shown), the intermittent extension and retraction of the movable shafts of the two hydraulic cylinders 8 are then adjusted to drive the fixed plate 9 and the plurality of knocking rods 10 to move up and down intermittently, and to knock the casting mold 6 intermittently;

[0029] During the intermittent telescopic movement of the movable shaft of the hydraulic cylinder 8, the connecting plate 16 drives the threaded sleeve 15 to move up and down along the side wall of the rifled rod 14, thereby driving the rifled rod 14 to rotate intermittently in the positive and negative directions. At this time, the vertical rod 11 drives the incomplete gear 12 to rotate intermittently in the positive and negative directions. When the incomplete gear 12 rotates and meshes with the toothed plate 13, the toothed plate 13 drives the placement ring 4 to move, driving the casting mold 6 to move, and driving the springs 5 on both sides of the placement ring 4 to contract and extend respectively. When the incomplete gear 12 rotates and separates from the toothed plate 13, at this time, under the elastic force of the multiple springs 5, the placement ring 4 is driven to move back to its original position. Therefore, during the intermittent telescopic movement of the hydraulic cylinder 8, the placement ring 4 drives the casting mold 6 to move back and forth, accelerating the demoulding of the cast parts, avoiding the need to manually lift and shake the casting mold in the prior art, thereby accelerating the demoulding efficiency, and cooperating with the automatic knocking to improve the demoulding efficiency;

[0030] The finally demoulded cast parts will fall on the buffer pad 17 and can be collected therefrom.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
