Referring to fig. 1 and 2, the utility model provides a sand mould casting sand box heightening structure, which comprises a frame body 1 formed by four heightening plates which are connected end to end in sequence.

Referring to fig. 3 and 4, in order to describe in detail the environment of use of the sand-mold casting flask heightening structure of the present embodiment, the present embodiment further proposes a sand-mold casting heightening structure, which includes a main box body 2 and the sand-mold casting flask heightening structure; the top of the main box body 2 is opened, and the frame body 1 is supported above the main box body 2.

In the specific use process of the sand mold casting heightening sand box, according to the requirement of the sand mold, the heightening structure with the proper height is placed on the main box body, and the sand box is integrally heightened, so that the sand mold is completely positioned in the sand box, and the high-temperature resistant particles can completely cover the outside of the cavity part of the sand mold.

In the embodiment, the sand mold casting sand box heightening structure and the heightenable sand box are provided, the sand box heightening structure comprises a frame body formed by sequentially connecting four heightening plates end to end, the top of the main box body is opened, and the frame body is supported above the main box body. Through the sand mould casting sand box of above-mentioned optimal design heightens the structure and can heighten the sand box, heightens the structure through setting up, highly carries out the dilatation to current not sand box of co-altitude, reduces the cost of customization sand box again, increases production efficiency, improves idle sand box utilization ratio, realizes that a case is multi-purpose, has also reduced the occuping of warehouse space simultaneously.

In a specific embodiment, the sand-mold casting heightening structure comprises a plurality of sand-mold casting sand box heightening structures arranged in sequence from top to bottom.

In order to realize the expansion of the heightening structure of the multi-level sand box, referring to fig. 1, in one embodiment of the heightening structure of the sand box of the present embodiment, at least one of the heightening plates has a first supporting projection 11 on an inner wall thereof, and the upper heightening structure is supported on the lower heightening structure by the first supporting projection; by adopting the design mode, a plurality of heightening plates can be directly welded in sequence to form the frame body, and then the first supporting lug is welded on the inner wall of the frame body, so that the processing is easy and the cost is low.

Accordingly, referring to fig. 3, the inner wall of the main case 2 is provided with at least one second supporting protrusion 21, and the lower end of the frame body 1 is supported in the main case 2 by the second supporting protrusion 21.

Referring to fig. 2 and 4, in another embodiment of the sand box heightening structure of the present embodiment, an upper stepped groove 12 opened along the top opening may be further provided on the inner wall of the frame 1; and/or the outer wall of the frame body 1 is provided with a lower step groove 13 arranged along the bottom opening; the vertical heightening structure is matched with the upper step groove and the lower step groove, so that the vertical heightening structure is standardized in size, and the modularization of the frame structure is realized.

Referring to fig. 5, in order to facilitate the whole sand mold to be placed into the sand box before casting or to be taken out of the sand box after casting, the heightened sand box of the embodiment further comprises a support base 3, the support base 3 is positioned in the main box body 2, and a sand mold support position is arranged on the top of the support base 3. When casting, the sand mold may be placed on the sand mold placement position of the support base 3, and then the sand mold 10 may be put into the sand box 20 through the support base 3.

In order to avoid the bottom leakage of the sand mold when the bottom groove of the sand mold is suspended, a supporting block 31 can be arranged on the supporting base 3, the bottom groove of the sand mold 10 is supported through the supporting block 31, and the bottom of the sand mold is prevented from being suspended.

In a further specific embodiment, a plurality of hoisting rods 4 are arranged on the supporting base 3, the hoisting rods 4 extend upwards from the supporting base 3 and are arranged around the sand mold placing position, and hoisting parts are arranged at the upper ends of the hoisting rods 4; the hoisting rod is convenient for integrally placing the supporting base and the sand mold into the sand box before casting, and integrally taking out the supporting base and the sand mold from the sand box after casting. In the concrete design of the hoisting rod, the hoisting rod can adopt a screw, and the lower end of the screw is arranged on the supporting base in a threaded manner.

Because in the casting field, the sand mould often divide into case and nowel, some have one or more middle casees in addition, need the mould assembling before the pouring, for guaranteeing that the metal liquid of die cavity the inside can not outflow during the mould assembling, put forward higher requirement to the die joint laminating sealing degree of case from top to bottom, nevertheless when actual operation, the condition of laminating not tight can be inevitable takes place, will ooze the metal liquid from the die joint gap that the sand mould contacted like this, commonly called "run out". Therefore, referring to fig. 6, in order to ensure the reliability of the closing of the upper and lower dies, a gravity pressure plate 5 is further arranged on the support base 3, the gravity pressure plate 5 is located above the sand mold placing position, and the closing of the upper and lower dies is pressed by the gravity pressure plate. In addition, the edge of the gravity pressing plate 5 can be provided with a clamping piece 51 matched with the hoisting rod 4, so that the gravity pressing plate is convenient to position.

In addition, a limit nut 6 installed in a threaded mode is sleeved on the hoisting rod 4, and the limit nut 6 is located above the gravity pressing plate 5; on the one hand, the gravity clamp plate passes through the holder and cooperates with the hoist and mount pole, and with the sand mould constraint on supporting the base, reliability when guaranteeing the bulk movement, on the other hand, when the sand mould was placed and is supported on the base, through rotatory stop nut, adjustable gravity clamp plate was to the packing force of sand mould, improved and compressed tightly the reliability, avoided gravity clamp plate position to remove simultaneously.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
