Description

Technical Field

[0001] The utility model belongs to the technical field of casting, in particular to a casting mold fastening device. Background Art

[0002] Casting refers to a metal forming process. During the metal casting process, molten metal is poured into a pre-made mold and the metal inside the mold is solidified and fixed. Since the casting mold has a certain shape and size, different casting molds can be used to produce metal parts or blanks of different shapes and sizes. After the casting mold is closed, the fastening device will be controlled to fasten the upper mold and the lower mold to avoid misalignment of the upper mold and the lower mold, so as to better cast metal parts.

[0003] After searching, a patent document with patent announcement number CN218591800U discloses a fastening device for casting mold processing, including a base plate, and also includes: a fastening assembly, the fastening assembly is fixed on the base plate, the fastening assembly includes a first cylinder, a first fixed plate, a motor, a rotating shaft, and a second fixed plate, the first cylinder is fixed on the base plate, the first fixed plate is fixed on the push rod of the first cylinder, the motor is fixed on the first fixed plate, one end of the rotating shaft is fixed on the top of the output shaft of the motor, and the other end is fixed on the second fixed plate. When it is in use, the position of the second box body on the first box body will not be dislocated under the touch or impact of external force, which can ensure the accuracy of the cavity surrounded by the two sand molds in the second box body and the first box body, and ensure the accuracy of the cast product.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing fastening device for casting mold processing, during use, the second fixing plate is driven to rotate by controlling the motor to rotate the second box body until the second box body is rotated and adjusted to the top of the first box body, so that the first box body and the second box body are completely closed. However, it is not convenient to limit the rotation angle of the second box body, and it is not convenient to determine the rotation angle of the second box body, which will cause the rotation angle of the second box body to be too large or too small, which is not conducive to the complete closure of the first box body and the second box body.

[0006] 2. In the use of the existing fastening device for casting mold processing, the distance between the second box body and the first box body is adjusted by controlling the first cylinder, the position of the second box body is adjusted by controlling the rotation of the motor, and the height of the second limit assembly is adjusted by controlling the second cylinder. In this way, the existing fastening device for casting mold processing needs to be powered on before it can be used, which limits the applicable site of the existing fastening device for casting mold processing and reduces the applicable scope of the existing fastening device for casting mold processing.

[0007] Therefore, we provide a casting mold fastening device to solve the above-mentioned problems. Utility Model Content
