Description

Technical Field

[0001] The utility model belongs to the technical field of V-method casting, and relates to a gating and risering fixing device for V-method casting process. Background Technique

[0002] V-method casting is a casting method that uses vacuum-sealed molding, also known as negative pressure molding or vacuum molding. It seals the sand box with a plastic film and uses a vacuum pump to extract the air inside the mold, forming a pressure difference between the inside and outside of the mold, so that the dry sand is compacted to form the required cavity. This casting method does not use adhesives, simplifies the sand treatment work, reduces the labor intensity of molding and cleaning the casting from adhering sand, and the recovery rate of used sand can reach more than 95%.

[0003] During the V-method casting process, especially during the sand filling and vibration compaction process of V-method casting, there is a problem that the gating and risering offset, resulting in the deformation of the gating system. Therefore, we design a gating and risering fixing device for V-method casting process. Summary of the Invention

[0004] The purpose of the utility model is to provide a gating and risering fixing device for V-method casting process to solve the problem of gating and risering offset and resulting in the deformation of the gating system as mentioned in the above background technique.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A gating and risering fixing device for V-method casting process includes two transverse connecting rods, four longitudinal connecting rods and a square frame. One end of the four longitudinal connecting rods is welded to the two ends of the two transverse connecting rods. Two connecting rods are welded to the middle parts of the two transverse connecting rods respectively. One end of the four connecting rods is welded to the four corners of the square frame. Two reinforcing connecting rods are arranged between the two transverse connecting rods. The length of the reinforcing connecting rods is equal to the width of the square frame. A gating and risering perforation position is formed between the two reinforcing connecting rods.

[0006] In the above-mentioned gating and risering fixing device for V-method casting process, the lengths of the two transverse connecting rods are both 500 millimeters, and the distance between the two transverse connecting rods is 57 millimeters.

[0007] In the above-mentioned gating and risering fixing device for V-method casting process, the distance between the two longitudinal connecting rods on the same transverse connecting rod is 400 millimeters.

[0008] In the above-mentioned gating and risering fixing device for V-method casting process, the length of the square frame is 60 millimeters.

[0009] In the above-mentioned gating and risering fixing device for V-method casting process, the length of the longitudinal connecting rod is 80 millimeters.

[0010] Compared with the prior art, the advantages of the riser fixing device for the V-process casting process of the present utility model are as follows: The claw feet at both ends are fixed on the sand box through four longitudinal connecting rods, so that the fixing device cannot move left and right. The riser passes through the square frame in the middle and there is a riser perforation position formed between the reinforcing connecting rods, so that the riser can be fixed, ensuring that the riser does not shift during the sand adding and vibration compaction process.
