Description

Technical Field

[0001] The invention relates to the technical field of metal casting, in particular to a casting device used for pump processing. Background Art

[0002] A casting mold refers to a model used to obtain qualified parts. Ordinary manual modeling often uses wooden models and plastic models, while mechanical modeling often uses metal models, such as aluminum models and iron models.

[0003] Through searching the prior art, it was found that Chinese patent with publication number CN214977701U discloses a demolding device for a brake pump casting mold, which can drive the fan to move back and forth through the movement of the upper mold groove. When the upper mold groove moves upward, the fan will be moved to the top of the upper mold groove.

[0004] However, it is worth considering that when the movable mold and the fixed mold are separated, the temperature of the surface of the casting is still relatively high. It needs to be cooled by a fan for a period of time before the staff can remove the casting from the fixed mold. While waiting for the casting, the casting has been on the fixed mold, resulting in the fixed mold having to wait for the temperature of the surface of the casting to drop to within the preset range before the casting can be separated from the fixed mold. The time interval between the two castings is relatively long, which reduces the casting efficiency of the casting mold and has certain limitations.

[0005] Therefore, in order to solve the above problems, a related facility that better meets the usage requirements is needed. Summary of the invention

[0014] After the raw material is formed, the lifting seat and the movable mold are driven to move upward by the first hydraulic telescopic rod, and at this time the second tension spring is in a tensioned state, and the second tension spring applies a pulling force to the movable block and the support column to make the support column close to the inclined surface on the support plate. As the lifting seat continues to move upward, the fixed column slides upward relative to the prism, the first tension spring is in a tensioned state, and the first slide block slides down relative to the first rectangular hole. When the movable mold is separated from the casting, the lifting seat drives the inclined surface on the support block to contact the slide plate through the fixed plate. As the lifting seat continues to move upward, the support block pushes the slide plate to move horizontally, increasing the length of the slide plate in the second groove, and the first compression spring is in a compressed state. The first compression spring applies pressure to the slide plate. The slide plate is made to fit tightly against the inclined surface on the support block.

As the lifting seat moves upward, the lifting seat drives the fixed column, the first slider, the prism and the support box to move upward synchronously, and the end of the support column slides on the inclined surface of the support plate. When the support column moves upward, the support plate pushes the movable block and the clamping block to move. When several clamping blocks clamp the exposed casting, the end of the support column away from the movable block slides from the inclined surface of the support plate to the side of the support plate facing the fixed column. As the lifting seat continues to move upward, the lifting seat drives the fixed column, the clamping block and the casting to move upward synchronously, and finally the casting is separated from the fixed mold. When the blanking assembly needs to move the casting from the top of the fixed mold to the blanking station, the first hydraulic telescopic rod drives the lifting seat to move continuously upward, and the end of the support column away from the movable block slides into the first slide groove, and the second tension spring drives the movable block and the clamping block to move synchronously, so that the several clamping blocks no longer clamp the casting, and as the lifting seat and the clamping block continue to move upward, the lifting seat and the clamping block are moved upward synchronously. Move up, several clamping blocks are no longer located on one side of the casting, and the fixation of the casting is released. The unloading assembly can move the casting from the top of the fixed mold to the unloading station. According to the shape of the casting, the pressing ring is driven to move up by the second hydraulic telescopic rod. The pressing ring no longer presses the bottom of the support plate, and the limitation on the position of the support plate is released. The staff drives the support plate to slide relative to the guide plate and the annular box to change the initial position of the support plate. The second tension spring drives the movable block and the support column to move synchronously with the support plate, so as to adjust the initial spacing between the clamping block and the casting. The pressing ring is driven to move down by the second hydraulic telescopic rod. The bottom of the pressing ring presses the top of the support plate, so that the support plate can be fixed relative to the guide plate and the annular box.

[0039] Working principle: When the lifting unit drives the lifting seat 4 to move downward so that the movable mold 3 and the fixed mold 2 are molded together, the raw material is injected into the mold cavity of the movable mold 3 and the fixed mold 2 through the pouring pipe 5. When the raw material is formed, the lifting unit drives the lifting seat 4 and the movable mold 3 to move upward, and the movable mold 3 is separated from the casting to expose the molded casting. The casting is driven upward by the ejector, and the casting is no longer adhered to the inner wall of the mold cavity of the fixed mold 2. At this time, the driving structure drives a number of clamping blocks 6 to clamp the casting. As the lifting seat 4 continues to move upward, the clamping blocks 6 pull the casting out of the fixed mold 2, and the pulled out casting is moved from the top of the fixed mold 2 to the unloading station through the unloading assembly. There is no need for the staff to directly take the casting, which reduces the time interval between two castings, improves the casting efficiency, and is convenient for practical use.

[0040] After the raw material is formed, the lifting seat 4 and the movable mold 3 are driven to move upward by the first hydraulic telescopic rod 12, and at this time the second tension spring 22 is in a tensioned state, and the second tension spring 22 applies a pulling force to the movable block 15 and the support column 16, so that the support column 16 is in close contact with the inclined surface on the support plate 18. As the lifting seat 4 continues to move upward, the fixed column 13 slides upward relative to the prism 21, the first tension spring 17 is in a tensioned state, and the first slide block 24 slides down relative to the first rectangular hole 23. When the movable mold 3 is separated from the casting, the lifting seat 4 drives the inclined surface on the support block 40 to contact the slide plate 37 through the fixed plate 39. As the lifting seat 4 continues to move upward, the support block 40 pushes the slide plate 37 to move horizontally, increasing the length of the slide plate 37 in the second groove 36. The first compression spring 38 is in a compressed state, and the first compression spring 38 applies pressure to the slide plate 37 so that the slide plate 37 is in close contact with the inclined surface on the support block 40. When the deformation of the first compression spring 38 reaches a preset value, as the support block 40 moves upward, the support block 40 drives the slide plate 37, the fixed block 35, the lifting plate 31 and the ejector rod 32 to move upward synchronously, and the lifting plate 31 slides relative to the first guide column 33. The design of the first guide column 33 allows the lifting plate 31 to move smoothly in the vertical direction. The design of the anti-slip plate 34 prevents the lifting plate 31 from separating from the first guide column 33. When the ejector rod 32 drives the casting to move upward, the casting is no longer adhered to the inner wall of the cavity of the fixed mold 2.
