Due to the limited space of the workshop, the sand boxes in a factory are often of fixed specifications and quantities under the premise of meeting the production needs of casting products. When taking on new castings, they will be restricted by the specifications of the sand boxes. When the height of the casting is too high or the molding height does not match the height of the sand box, the casting cannot be combined in the sand box. To address this problem, some sand box processing structures are disclosed in the prior art, such as a sand mold casting sand box heightening structure and a heightenable sand box disclosed in the authorized patent document with application number CN202122941687.7. The sand box heightening structure includes a frame surrounded by four heightening plates connected end to end and other components.

[0003] Since the size of the heightening plate in the above scheme is fixed, the size of the heightening structure supported by the heightening plate is fixed, so that the above-mentioned heightening structure can only adapt to one size of sand box, which reduces its practicality and adaptability. In addition, when a side of the heightening structure is damaged, this side of the heightening structure needs to be replaced, resulting in waste. Based on this, the present application proposes a universal heightening tooling for sand boxes for cast steel. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a universal heightening tool for a sand box for steel casting, comprising a universal part 1, a length adjusting part 2 and a compensating part 3. One end of the universal part 1 and one end of the length adjusting part 2 are both provided with a limit clamp, and the thickness value of the universal part 1 is the same as the thickness value of the length adjusting part 2, and the height value of the universal part 1 is the same as the height value of the length adjusting part 2. With such an arrangement, when the heightening tool is spliced, the other end of the universal part 1 can be inserted into the limit clamp adjacent to it, and the other end of the length adjusting part 2 can also be inserted into the limit clamp adjacent to it. Then, bolts are used to connect the other end of the universal part 1 or the other end of the length adjusting part 2 to the limit clamp adjacent to it, so as to realize the splicing of the heightening tool.

[0023] The limiting clamp includes an outer clamping piece 6 and an inner clamping piece 7. The outer side of one end of the universal part 1 and the outer side of one end of the length adjusting part 2 are fixed with the outer clamping piece 6, and the inner side of one end of the universal part 1 and the inner side of one end of the length adjusting part 2 are fixed with the inner clamping piece 7. The other end of the universal part 1, the other end of the length adjusting part 2 and the outer clamping piece 6 are all provided with threaded holes 5 adapted to bolts. Through the setting of the threaded holes 5, the connection between the universal part 1 and the length adjusting part 2 or two adjacent length adjusting parts 2 can be achieved by using bolts, which is convenient for splicing of the tooling.

[0024] The top of the inner clamp 7 and the top of the outer clamp 6 are in the same plane, and a fixing hole 8 is provided at the bottom end of the inner clamp 7. The fixing hole 8 is located below the universal part 1. Through the arrangement of the inner clamp 7 and the fixing hole 8, the heightening tooling can be connected to the sand box by bolts.

[0025] The height values ​​of the length adjusting piece 2, the universal piece 1, the outer clip 6 and the compensation piece 3 are the same, the length value of the compensation piece 3 is the same as the length value of the length adjusting piece 2, and the thickness value of the compensation piece 3 is twice the thickness value of the length adjusting piece 2. By using the compensation piece 3, two adjacent length adjusting pieces 2 can be connected together.

[0026] From the above description, it can be known that when the heightening tool is spliced, the number of length adjustment parts 2 or compensation parts 3 can be increased according to needs, so that the size of the heightening tool can adapt to a variety of sand boxes, thereby improving the adaptability of the tool. When the heightening tool is in use, only the damaged parts need to be replaced, and the remaining parts can continue to be used, thereby reducing costs.

[0027] The universal part 1 is L-shaped, and the corner of the universal part 1 is an arc-shaped structure protruding outward, and there is a smooth transition between the arc-shaped structure and the end of the universal part 1. A reinforcing member 4 is fixed to the inner wall of the universal part 1, and the reinforcing member 4 is L-shaped and fixedly connected to the inner wall of the arc-shaped structure. By setting the reinforcing member, the strength of the corner of the universal part 1 can be improved, and the service life of the heightening tooling can be extended.

[0028] In summary: when the universal heightening tooling for the cast steel sand box is implemented, the user uses the same steel plate material as the sand box to make the universal part 1, the length adjustment part 2 and the compensation part 3 according to the actual situation to meet the strength requirements of safe production. The user adjusts the number of the length adjustment parts 2 and the number of the compensation parts 3 according to the size of the sand box. During the splicing process, if the compensation part 3 is not needed, the user inserts one end of the length adjustment part 2 and one end of the universal part 1 into the matching limit clamps respectively, and the universal part 1 can be connected to the length adjustment part 2 by bolts, and the connection between two adjacent length adjustment parts 2 can be achieved by bolts. The length adjustment part 2 and the universal part 1 can be spliced ​​into the heightening tooling as shown in the attached figure. Figure 5 As shown; if the compensating member 3 is needed, the end of the universal member 1 is connected to the length adjusting member 2 by bolts and a limiter, and the other end of the length adjusting member 2 and the other end of the universal member 1 or the ends of two adjacent length adjusting members 2 away from the limiter connected thereto are connected by the compensating member 3, as shown in the attached Figure 1 shown.

[0029] When the heightening tool is in use, the heightening tool is placed on the top of the sand box, and the heightening device is fixed to the sand box by bolts to achieve heightening of the sand box. Figure 2 shown.
