Evaporative pattern casting sand box

Abstract

The invention discloses an evaporative pattern casting sand box. The evaporative pattern casting sand box comprises an upper sand box body and a turbine discharging machine. The lower side of the upper sand box body is connected with a middle sand box body. The lower side of the middle sand box body is connected with a lower sand box body. The outer side of the lower sand box body is provided withan opening sealing plate. The outer side of the opening sealing plate is provided with a power plug. The inner end of each water supply pipe is connected with a cooling cavity. The outer sides of thecooling cavities are connected with the upper sand box body, the middle sand box body and the lower sand box body through reinforced fixing rods. Air permeable plates are connected between the cooling cavities. A fine screen and a coarse screen are fixed into each air permeable plate. The evaporative pattern casting sand box is provided with the upper sand box body, the middle sand box body and the lower sand box body. The box bodies of the evaporative pattern casting sand box can be disassembled. The interior of the evaporative pattern casting sand box can be overhauled conveniently, and theworking dimensions of the evaporative pattern casting sand box can also be changed. Accordingly, the evaporative pattern casting sand box can be used for conducting casting operation on different types of models, and the usage efficiency of the evaporative pattern casting sand box is improved.

Description

Technical field [0001] The invention relates to the technical field of lost foam casting devices, in particular to an lost foam casting sand box. Background technique [0002] Lost foam casting is a new type of casting method in which metal liquid occupies the vaporized model space and solidifies and cools to form castings. In the lost foam casting process, the indispensable device is the casting sand box, but currently some casting sand boxes There are still certain problems in use. For example, the use of some foundry flasks has certain limitations. Because its size is difficult to change, it can only be used for casting of fewer types of models, which reduces the cost of the foundry flask. Use efficiency, and some casting sand boxes have poor performance, and it is inconvenient to clean and repair the inside of the casting sand boxes. Therefore, we propose a lost foam casting sand box to solve the above-mentioned problems. Summary of the invention [0003] The purpose of the p...
