This phenomenon has become a problem that people in this field need to solve urgently. Utility Model Content
[0003] The utility model aims to provide a sliding sand box centering mechanism to solve the problems raised in the above background technology.
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a slip-off sand box centering mechanism, comprising an upper sand box and a lower sand box, wherein the upper sand box and the lower sand box are both connected to an external hydraulic cylinder;
[0005] The upper sand box includes a limiting block 1, a clamping sleeve, and a centering block 1, and the lower sand box includes a centering block 2;
[0006] The first limit block is fixedly installed on the outer side of the upper sand box, the clamping sleeve is fixedly installed above the inner wall of the upper sand box, the first centering block is fixedly installed between the clamping sleeve and the inner wall of the upper sand box, and the second centering block is fixedly installed on the outer side of the lower sand box;
[0007] A plurality of sand grooves are arranged on the surface of the upper sand box.
[0008] The utility model further illustrates that the front and rear of the upper sand box are fixed with stable slide grooves, and the front and rear of the lower sand box are fixed with stable blocks;
[0009] The stabilizing slide groove and the stabilizing block are aligned with each other.
[0010] The utility model further describes that the inner sides of the upper and lower ends of the stable slide groove are provided with arc angles;
[0011] The upper end of the stabilizing block is arc-shaped.
[0012] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the sand box adopted by the utility model squeezes the upper sand box and the lower sand box through the hydraulic cylinder, so that the two squeeze the gravel mutually, thereby forming. During the forming process, the upper sand box moves downward until it is blocked by the second center block, and at the same time, the lower sand box moves upward until it is inserted between the clamping sleeve and the inner wall of the upper sand box, and finally blocked by the first center block, so as to limit the upper sand box and the lower sand box to ensure that the sand after forming is located in the center position, improve the gravel forming quality, prevent the subsequent gravel from being scattered due to uneven force on one side, thereby fully improving the forming quality;
[0013] During molding, the upper sand box and the lower sand box are close to each other, and the stabilizing block is aligned with the stabilizing chute and inserted into the stabilizing chute, thereby playing a stabilizing role, preventing the sand box from shaking left and right and forward and backward during the molding process to affect the molding quality and improve the molding stability; and the stabilizing block at the arc-shaped upper end can be smoothly inserted into the stabilizing chute, thereby reducing the wear between the two and improving smoothness.
