Description

Technical Field

[0001] The utility model belongs to the technical field of sand casting, and particularly relates to a sand collecting device for sand casting. Background Technique

[0002] Sand casting refers to a casting method for producing castings in a sand mold. Castings of steel, iron, and most non-ferrous alloys can be obtained by sand casting. Since the molding materials used in sand casting are inexpensive and easily available, and the mold manufacturing is simple, it can adapt to single-piece production, batch production, and mass production of castings. For a long time, it has been the basic process in casting production.

[0003] The existing sand collecting method is to manually carry the upper and lower parts of a small sand box and pour the sand in the sand box into a sand collecting box or a sand collecting bin. For a large sand box, the upper and lower parts of the sand box are lifted by a crane, and then the sand box is moved above the sand collecting box or the sand collecting bin, and then the sand box is flipped to pour the sand in the sand box into the sand collecting box or the sand collecting bin. This results in low efficiency in collecting sand, and at the same time, it is time-consuming, laborious, and costly.

[0004] Therefore, in order to solve the above problems, it is necessary to design a sand collecting device for sand casting. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sand collecting device for sand casting to solve the technical problem of inconvenient sand collection.

[0006] To solve the above technical problem, the utility model provides a sand collecting device for sand casting, including:

[0007] A sand collecting box and a support block located in the sand collecting box; wherein

[0008] A placing portion is provided on the support block;

[0009] Rotating shafts are arranged on both sides of the support block and are respectively connected to the sand collecting box by bearings;

[0010] A lower sand box is arranged in the placing portion;

[0011] A plurality of bolts penetrate through the support block and are engaged with the lower sand box to fix the lower sand box in the placing portion;

[0012] The rotating shaft is adapted to drive the support block and the lower sand box to rotate when rotating, so that the used sand in the lower sand box is poured into the sand collecting box.

[0013] Further, cushion blocks are arranged on both sides of the lower sand box; wherein

[0014] The cushion blocks are arranged in the placing portion; and

[0015] The cushion blocks are in contact with the lower sand box and the inner wall of the placing portion.

[0016] Further, one end of any of the rotating shafts is connected with a coupling; among which

[0017] The other end of the coupling is connected with a motor; and

[0018] The motor is adapted to drive the rotating shaft to rotate through the coupling.

[0019] Further, a first support frame is arranged on the outer side of the sand collecting box;

[0020] A discharge pipe is arranged at the bottom of the sand collecting box.

[0021] Further, a second support frame is arranged on one side of the first support frame; among which

[0022] The motor is fixed on the second support frame.

[0023] The beneficial effects of the present utility model are as follows:

[0024] (1), by removing the upper sand box and the formed casting, at this time, the motor is started, and the motor drives the rotating shaft to rotate a certain angle through the coupling. The rotating shaft drives the other rotating shaft to rotate through the lower sand box, so that the lower sand box is turned over. At this time, the sand material in the lower sand box falls into the sand collecting box and is discharged through the discharge pipe at the bottom of the sand collecting box. Through the above steps, the effects of convenient sand collection and improved sand collection efficiency are achieved.

[0025] (2), in the present utility model, the cushion blocks are selected with models adapted to the length of the lower sand box to ensure that the cushion blocks are in contact with the inner walls of the lower sand box and the placing part, so as to achieve the effects of adapting to different models of lower sand boxes and preventing the lower sand box from moving.
