Detailed Description

To further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solutions of the present invention and are not to limit the present invention.

The first embodiment of the utility model describes a device for limiting a casting molding middle sand box, which comprises a bottom plate 6 and two box clamping devices 8;

a U-shaped plate 4 is fixed at one end of the bottom plate, and a cushion block 10 is fixed on the upper end surface of the bottom plate;

the box clamping device comprises a clamping frame 5, a sliding shaft 2 and two pressure rods 3, wherein a fixing lug 16 on one side of the clamping frame is fixed with the sliding shaft, two ends of the sliding shaft penetrate through sliding holes 9 in the U-shaped plate, and the sliding holes of the U-shaped plate are used as sliding ways for the sliding shaft to slide up and down;

the two compression bars are positioned at the upper side and the lower side of the clamping frame and are respectively fixed on the clamping frame through triangular support plates 12, and the compression bars are in contact with the U-shaped plate;

and one side surface of the clamping frame is in threaded connection with two adjusting bolts 1.

In the second embodiment, the present embodiment is further described with respect to the flask stop device in the first embodiment, wherein a pressure pad 7 is fixed to the pad block.

In a third embodiment, the third embodiment further describes a flask-limiting device for a cast molding flask according to the first embodiment, wherein two ends of the sliding shaft on the bottom side of the flask clamper are provided with threads, and nuts are screwed on the threads.

In the fourth embodiment, which is a further description of the flask stop device in the first embodiment, four corners of the bottom plate are respectively connected with the adjusting feet 11 by screw threads.

The working principle is as follows: in use, as shown in fig. 4 and 5, the clamping frames of the upper and lower box holders are respectively clamped on the upper box body 14 and the lower box body 15 of the sand box 13, the clamping method is that when the upper box body and the lower box body are buckled together to wait for taking off the upper box body, the device is placed at the sand box to enable the clamping frames of the two box holders to be respectively inserted at the sand box to enable the inner side surfaces of the clamping frames to be contacted with the side surfaces of the sand box, as shown in fig. 4, then each adjusting bolt is adjusted to enable the adjusting bolt to be propped against the side surfaces of the sand box to clamp the sand box, the clamping of the sand box is completed, then handles at the two sides of the upper box body are held by hands to lift the upper box body, the upper box body is lifted, because the sliding shaft is matched with the sliding hole, and the two pressing rods are contacted with the U-shaped plate, the movement of the clamping frames can be limited, the clamping frames can only vertically move up and down, the upper box body is vertically lifted, and when the sliding shaft is lifted to move to the uppermost end of the sliding hole, as shown in fig. 5, the upper box body is turned over by 180 degrees by holding the upper box body, after turning, because two pressure rods are also in contact with a U-shaped plate, the clamping frame vertically slides downwards, then the upper box body is lightly placed by holding the upper box body and then placed on a cushion block, at the moment, the clamping frame is vertically slid downwards, the upper box body is ensured to be horizontally placed on the cushion block, the sand mold is prevented from being influenced due to partial placement, meanwhile, handles on two sides of the upper box body are held by holding the upper box body after mold removal is finished, the upper box body is turned over by 180 degrees after the uppermost end of the sliding hole is lifted, then the upper box body is lightly placed on the lower box body by holding the upper box body, the positioning effect can be achieved, alignment between the upper box body and the lower box body is ensured, the device can limit the upper box body in the lifting and placing processes, and four adjusting feet at the bottom of the bottom plate are used for horizontally placing the adjusting bottom plate.
