Description

Technical Field

[0001] The utility model belongs to the field of mold sand cores, and particularly relates to a mold sand core head pressing device. Background Art

[0002] Core head is a special term in casting. Core head refers to the protruding part on the pattern, which forms a core seat in the mold and places the core head; or it refers to the overhanging part of the core, which does not form the outline of the casting, but falls into the core seat to position and support the core.

[0003] At present, a Chinese utility model with announcement number: CN210996326U provides a sand core clamping device, including a gear, a bracket, a gear frame, a slide, a bearing, a lifting frame, a base plate, a handle, a pressure plate, a clamping plate and a tightening buckle; the gear is connected to the shaft of the handle through a key connection, and the inner ring of the bearing is connected to the shaft of the handle through an interference fit; the left end of the gear frame is connected to the side of the bracket by welding, and the outer ring of the bearing is connected to the inner ring of the gear frame by an interference fit; the slide is connected to the front of the bracket by welding at two places, and the bottom surface of the bracket is connected to the upper surface of the base plate by welding; the upper surface of the pressure plate is connected to the lower end of the lifting frame by welding; in summary, it can be seen that the clamping method of the existing sand core clamping device is improved, and the force is converted into the clamping force of the pressure plate by rotating the handle. The operation is simple and easy for novices to learn, the function of clamping the mold is increased, the displacement of the mold is reduced during the clamping process, and the stability of the equipment is improved.

[0004] When the mold needs to be replaced, the clamping device needs to adjust the tightening buckles on both sides. When reinstalling the mold, in order to ensure the cooperation between the mold and the pressure plate, the position of the clamping plate needs to be repeatedly adjusted to ensure that the mold is directly under the pressure plate. This operation is inconvenient to repeatedly adjust. At the same time, when the handle is turned, after the pressure plate is tightened, releasing the force on the handle will cause rebound and lose the clamping effect on the mold, which brings inconvenience to the operator.
