Description

Technical Field

[0001] The utility model relates to the field of casting molds, in particular to a pneumatic demoulding device. Background Art

[0002] Casting products all require a mold, and then mold sand is covered on the mold. After the mold sand is formed, demolding is carried out. After demolding, a mold shape appears in the mold sand, and then pouring is carried out, so that the final product comes out. In the process of demolding, it is found that after the mold sand is formed, in order to demold, it is sometimes done manually. In the process of demolding, because the mold sand fits the mold more firmly after forming, a certain amount of strength is required to complete the demolding work manually. In this way, the operator will not have the strength to complete the work after a long time, and the work efficiency will be significantly reduced. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pneumatic demoulding device to solve the problems of high labor intensity and low work efficiency in the current casting mold demoulding process relying on manual labor.

[0005] A pneumatic demoulding device is provided, comprising:

[0006] A base, on which a plurality of guide pillars are fixedly arranged, and a mold bottom plate is fixedly arranged on the upper end of each guide pillar;

[0007] A lifting plate, the lifting plate is located between the base and the bottom plate of the mold, and forms a sliding fit with each guide column. A plurality of top columns are arranged at the upper end of the lifting plate, and a top hole for the top columns to pass through is provided on the bottom plate of the mold. A roller is arranged at the lower end of the lifting plate;

[0008] A push cylinder is horizontally arranged on the base, the push cylinder is connected to a push block, and the push block is provided with an inclined surface for cooperating with a roller;

[0009] The pushing cylinder drives the pushing block to move horizontally on the bottom plate, and the pushing block abuts against the roller via the inclined surface, driving each top column on the lifting plate to extend from the bottom plate of the mold.

[0010] Furthermore, a guide rail is arranged on the base, a slider is arranged at the lower end of the push block, the slider forms a sliding fit with the guide rail, and the push block moves linearly along the guide rail.

[0011] Furthermore, a wheel seat is arranged at the lower end of the lifting plate, and the roller is arranged on the wheel seat.

[0012] Furthermore, a guide bearing is arranged on the lifting plate, and the lifting plate forms a sliding fit with the guide column via the guide bearing.

[0013] Furthermore, the guide column includes a large-diameter column and a small-diameter column, and the lifting plate forms a sliding fit with the small-diameter column.

[0014] The beneficial effects of the utility model are:

[0015] The pneumatic demoulding device of the utility model can realize automatic demoulding by pushing the cylinder to move horizontally to drive the lifting plate to move up and down. Compared with the previous manual demoulding, it is more efficient and easier for people. It can improve work efficiency under the same working time.

[0016] The push cylinder is arranged horizontally to prevent the molding sand particles at the upper end from falling into the cylinder, thus ensuring the service life of the push cylinder.

[0028] A lifting plate 3, the lifting plate 3 is located between the base 1 and the mold bottom plate 2, and forms a sliding fit with each guide column 6, a plurality of top columns 31 are arranged on the upper end of the lifting plate 3, a top hole for the top columns 31 to pass through is provided on the mold bottom plate 2, and a roller 32 is arranged on the lower end of the lifting plate 3;

[0029] A push cylinder 4 is horizontally arranged on the base 1, and the push cylinder 4 is connected to a push block 41, and the push block 41 is provided with an inclined surface for cooperating with the roller 32;

[0030] The pushing cylinder 4 drives the pushing block 41 to move horizontally on the bottom plate, and the pushing block 41 abuts against the roller 32 via the inclined surface, driving each top column 31 on the lifting plate 3 to extend from the mold bottom plate 2.

[0031] In this embodiment, the number of guide pillars 6 is preferably 4, and the number of top pillars 31 is preferably 4.

[0032] The angle of the inclined surface on the push block 41 is less than 45°, and the angle should not be too large. In this embodiment, the inclined surface angle is preferably 30°.

[0033] The front end of the push cylinder 4 is connected to the push block 41 through a connecting rod.

[0034] The push cylinder 4 is arranged horizontally to prevent the molding sand from above from falling into the cylinder.

[0035] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, a guide rail 51 is disposed on the base 1 , and a slider 52 is disposed at the lower end of the push block 41 . The slider 52 forms a sliding fit with the guide rail 51 , and the push block 41 moves linearly along the guide rail 51 .

[0036] The guide rail 51 and the bottom plate are fastened with bolts, and the push block 41 and the slider 52 are also fastened with bolts. The cross section of the slider 52 is a U-shaped structure.

[0037] Specifically, as an optional implementation in this embodiment, Figure 2 Figure 3 As shown, a wheel seat is arranged at the lower end of the lifting plate 3, and the roller 32 is arranged on the wheel seat.
