[0031] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] As Figure 1-6 shown, a casting pouring and molding processing device includes a bottom mold 1 and a top mold 2, and a pouring cavity formed by enclosing the two, including:

[0033] A lifting block 3 slidably disposed at the bottom of the pouring cavity, which is driven to lift the casting;

[0034] Folded dust cleaning arms 4 circumferentially and arrayedly disposed on the lifting block 3, which include support rods 41 rotatable relative to the lifting block 3, and the support rods 41 rotate to a predetermined angle as the lifting block 3 moves upward;

[0035] A rotating ring 6 slidably engaged with the lifting block 3 through a keyway.

[0036] Specifically, the top mold 2 can move vertically along the axis of the bottom mold 1. When the upper end surface of the top mold 2 is flush with the upper end surface of the bottom mold 1, a pouring cavity is formed between the two. By default, the top of the lifting block 3 is flush with the bottom surface of the pouring cavity. A cylinder is provided at the bottom of the lifting block 3, and the folded dust cleaning arm 4 is located on the outer wall of the cylinder and will not interfere with the normal pouring process. The above technical processes are well-known technical common sense to those skilled in the art and will not be elaborated here.

[0037] Further, the casting liquid is injected into the casting cavity. After cooling, the casting liquid forms. Subsequently, the top mold 2 is moved upward, and the lifting block 3 is driven to lift the formed casting upward, so that the casting is demolded. During the upward movement of the lifting block 3, the support rod 41 rotates to a predetermined angle and contacts the bottom surface of the bottom mold 1. Subsequently, the rotating ring 6 can be driven to rotate manually or by a motor, thereby driving the lifting block 3 and the folding dust cleaning arm 4 provided thereon to rotate, and scraping the bottom surface of the bottom mold 1 through the support rod 41 to clean the inside of the bottom mold 1 and avoid the residue of slag ash after the casting cools down.

[0038] In the above technology, through the setting of the folding dust cleaning arm 4, during the upward movement of the lifting block 3, the support rod 41 rotates to a predetermined angle and contacts the bottom surface of the bottom mold 1. Subsequently, the rotating ring 6 can be driven to rotate manually or by a motor, thereby driving the lifting block 3 and the folding dust cleaning arm 4 provided thereon to rotate, cleaning the inside of the bottom mold 1 and avoiding the residue of slag ash after the casting cools down.

[0039] As an embodiment further provided by the present utility model, the folding dust cleaning arm 4 further includes:

[0040] A rotating rod 43 rotatably arranged, the end of which is rotatably connected to the support rod 41;

[0041] A brush rod 42 rotatably arranged at the first end of the support rod 41, and a resisting block 45 is arranged at the rotating part of the brush rod 42. The resisting block 45 can abut against the lifting block 3 to adjust the angle between the support rod 41 and the brush rod 42;

[0042] A sliding seat 32 slidably arranged, which is rotatably connected to the second end of the support rod 41, and the sliding seat 32 moves synchronously with the lifting block 3 through a transmission component.

[0043] Specifically, in the initial state, the resisting block 45 abuts against the bottom side of the lifting block 3, and the angle between the brush rod 42 and the support rod 41 is small, while the support rod 41 is close to the side wall of the bottom cylinder of the lifting block 3, so that the support rod 41, the brush rod 42 and the rotating rod 43 are all within the vertical projection of the lifting block 3. When the lifting block 3 moves upward, the sliding seat 32 is driven to move upward through the transmission component, so that the second end of the support rod 41 moves upward and approaches the rotating shaft of the rotating rod 43, and the angle between the support rod 41 and the outer wall of the cylinder gradually increases, driving the resisting block 45 to slide radially toward the edge of the lifting block 3. At the same time, the resisting block 45 is subject to the frictional resistance of the lifting block 3, and this frictional resistance points to the axis of the lifting block 3. The resisting block 45 rotates due to this frictional resistance until it stops rotating when it no longer abuts against the lifting block 3, so that the angle between the brush rod 42 and the support rod 41 increases, and the brush rod 42 extends out of the vertical projection range of the lifting block 3, as Figure 3 shown in the state, and contacts the inner wall of the bottom mold 1, and the dust is cleaned through the bristles provided on the brush rod 42;

[0044] Subsequently, the jacking block 3 is driven to move downward until the upper end surface of the jacking block 3 returns to the initial state flush with the bottom surface of the casting cavity. The sliding seat 32 moves downward driven by the transmission assembly, causing the second end of the support rod 41 to move downward. The included angle between the support rod 41 and the rotating rod 43 increases, and the support rod 41 approaches the outer wall of the cylinder. The brush rod 42 is driven by the first end of the support rod 41 to approach the jacking block 3. Subsequently, the abutting block 45 of the brush rod 42 abuts against the edge of the jacking block 3. At this time, the frictional resistance of the jacking block 3 against the abutting block 45 points to the edge of the jacking block 3, causing the abutting block 45 to rotate and drive the included angle between the brush rod 42 and the rotating rod 43 to become smaller, presenting a folded state as shown in Figure 5 shown.

[0045] As yet another embodiment further provided by the present utility model, the transmission gear set 5 includes:

[0046] A toothed ring 51 rotatably arranged and meshing with the first rack 33 for transmission, and a plurality of teeth are provided on the inner wall of the toothed ring 51;

[0047] An internal gear 52 rotatably arranged and meshing with the inner tooth surface of the toothed ring 51, and a driving gear 53 meshing with the second rack 34 is provided on its rotating shaft.

[0048] Specifically, the transmission assembly includes a first rack 33 arranged on the slide rail 31 and a second rack 34 arranged on the sliding seat 32. When the jacking block 3 moves upward, it drives the first rack 33 to move upward, thereby causing the toothed ring 51 to rotate. Taking the rotation direction of the toothed ring 51 at this time as the positive direction, subsequently, the internal gear 52 is driven by the toothed ring 51 to rotate positively, thereby driving the driving gear 53 to rotate positively. Moreover, the number of teeth and the radius of the driving gear 53 are both larger than those of the internal gear 52. Therefore, the tangential speed of the driving gear 53 is greater than that of the internal gear 52. The driving gear 53 drives the second rack 34 to slide. At this time, the sliding direction of the second rack 34 is the same as that of the first rack 33, but the stroke of the second rack 34 is longer than that of the first rack 33, causing the second rack 34 to move upward relative to the first rack 33, thereby driving the sliding seat 32 to move upward relative to the cylinder. When the jacking block 3 moves downward, the second rack 34 moves downward relative to the first rack 33, thereby driving the sliding seat 32 to move downward relative to the cylinder.

[0049] As yet another embodiment further provided by the present utility model, a tension spring 44 for pulling the support rod 41 is provided on the rotating rod 43.

[0050] Specifically, in the initial state, the brush rod 42 and the rotating rod 43 approach each other through the tension spring 44. As the jacking block 3 moves upward, the angle between the brush rod 42 and the rotating rod 43 gradually increases. At this time, the tension spring 44 is stretched to the limit, as shown in Figure 3 shown. The gravity of part of the support rod 41 and the brush rod 42 is offset by the tension of the tension spring 44, so that the angle of the support rod 41 is fixed.

[0051] As yet another embodiment further provided by the present utility model, both ends of the elastic member 46 are respectively disposed on the same side of the support rod 41 and the brush rod 42.

[0052] Specifically, a recess is provided in the middle of the elastic member 46. When the angle between the support rod 41 and the brush rod 42 is relatively small, the elastic member 46 is bent with the recess as the axis. At this time, the elastic member 46 is in a deformed and energy-storing state. When the angle between the support rod 41 and the brush rod 42 increases to nearly 180°, the deformation potential energy of the elastic member 46 is restored to the unbent state, thereby supporting and fixing the angle between the support rod 41 and the brush rod 42.

[0053] Working principle: The top mold 2 can move vertically along the axis of the bottom mold 1. When the upper end surface of the top mold 2 is flush with the upper end surface of the bottom mold 1, a casting cavity is formed between them. The casting liquid is injected into the casting cavity and forms a shape after cooling. Then, the top mold 2 is moved upward, and the lifting block 3 is driven to lift the formed casting upward to demold the casting. During the upward movement of the lifting block 3, the first rack 33 is driven to move upward, so that the toothed ring 51 rotates. Taking the rotation direction of the toothed ring 51 at this time as the positive direction, then the internal gear 52 is driven to rotate positively by the toothed ring 51, thereby driving the driving gear 53 to rotate positively. Moreover, the number of teeth and the radius of the driving gear 53 are both larger than those of the internal gear 52. Therefore, the tangential speed of the driving gear 53 is greater than that of the internal gear 52. The driving gear 53 drives the second rack 34 to slide. At this time, the sliding direction of the second rack 34 is the same as that of the first rack 33, but the stroke of the second rack 34 is longer than that of the first rack 33, so that the second rack 34 moves upward relative to the first rack 33, thereby driving the sliding seat 32 to move upward relative to the cylinder, so that the second end of the support rod 41 moves upward and approaches the rotating shaft of the rotating rod 43. The angle between the support rod 41 and the outer wall of the cylinder gradually increases, driving the abutting block 45 to slide radially toward the edge of the lifting block 3. At the same time, the abutting block 45 is subjected to the frictional resistance of the lifting block 3, and this frictional resistance points to the axis of the lifting block 3. The abutting block 45 rotates due to this frictional resistance until it stops rotating when it no longer abuts against the lifting block 3, so that the angle between the brush rod 42 and the support rod 41 increases, and the deformation potential energy of the elastic member 46 is restored to the unbent state, thereby supporting and fixing the angle between the support rod 41 and the brush rod 42. The brush rod 42 extends out of the vertical projection range of the lifting block 3, as Figure 3 shown in the state. Subsequently, the rotating ring 6 can be rotated manually or by a motor, and the ash can be cleaned by the bristles provided on the brush rod 42.

[0054] Subsequently, the jacking block 3 is driven to move downward until the upper end surface of the jacking block 3 returns to the initial state flush with the bottom surface of the casting cavity, causing the second rack 34 to move downward relative to the first rack 33, thereby driving the sliding seat 32 to move downward relative to the cylinder. The sliding seat 32 moves downward driven by the transmission component, causing the second end of the strut 41 to move downward. The angle between the strut 41 and the rotating rod 43 increases, and the strut 41 approaches the outer wall of the cylinder. The brush rod 42 is driven by the first end of the strut 41 to approach the jacking block 3. Subsequently, the abutting block 45 of the brush rod 42 abuts against the edge of the jacking block 3. At this time, the frictional resistance of the jacking block 3 against the abutting block 45 points to the edge of the jacking block 3, causing the abutting block 45 to rotate and drive the angle between the brush rod 42 and the rotating rod 43 to become smaller, presenting a folded state as shown in Figure 5 . The elastic member 46 is bent with the recess as the axis. At this time, the elastic member 46 is in a state of deformed energy storage.

[0055] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
