The invention provides a boiling structure of a sand shooting box, and relates to the technical field of sand shooting modeling. The boiling structure comprises a shell, at least one permeable plate arranged in the shell and a connecting mechanism used for connecting each permeable plate to the inner wall of the shell, wherein a gap is formed between each permeable plate and the shell; annular sealing strips are arranged in the gaps between the permeable plates and the shell, so that independent cavities are formed between the permeable plates and the shell; ventilation holes are formed in the permeable plates; and air inlets are formed in the positions, corresponding to the cavities, of the wall of the shell. According to the arrangement, the permeable plates separately form the independent cavities without mutual influence, even if one permeable plate is damaged, the operation of other permeable plates is not influenced, a sand shooting machine can still work, and the damaged permeable plate can be replaced after shutdown; and in addition, the permeable plates do not need to be bonded by a sealant, so that gas is not interfered by the smearing condition of the sealant, and the sand shooting is more stable and uniform.
Description
technical field [0001] The invention relates to the technical field of sand shooting molding, and more specifically, relates to a boiling structure of a sand shooting box and the sand shooting box. Background technique [0002] In the prior art, the boiling structure of the sand-shooting box is mainly composed of a plurality of ventilating plates, and the venting plate is provided with vent holes, and there is a gap between the venting plate and the inner wall of the sand-shooting box. The high-pressure gas enters into the sand-shooting box from the air-venting hole on the air-permeable plate, so that the molding sand in the sand-shooting box rolls and boils, so as to be better ejected from the sand-shooting port of the sand-shooting box. However, in the prior art, at the turning corner of the sand shot box, two air-permeable plates are vertically arranged and sealed by a sealant. This form mainly has the following problems: first, the flow of air will be affected by the sh...
