Sand floating machine

Abstract

The invention provides a sand floating machine, which comprises an air blower, a sand bucket, and an air delivery duct communicated with the sand bucket and the air outlet of the air blower, wherein the air inlet of the air blower is communicated with a refrigerating device. The refrigerating device is a flat plate type cooler, and the flat plate type cooler is fixedly arranged at the air inlet of the air blower. The sand floating machine provided by the invention has the advantages of being simple in structure and convenient to use, reducing the heat generated by long-time work of the air blower and floating sand, preventing the floating sand from clogging, and reducing the sand bucket cleaning number.

Description

technical field

[0001] The invention relates to the field of casting, in particular to a floating sand machine. Background technique

[0002] Floating sand machine is a commonly used sand hanging equipment in the investment casting industry such as gelatinous wax method. It is often used on precision casting products. To make the casting mold, it is necessary to pre-manufacture a wax mold according to the shape and size of the product, and then stick it on the surface of the wax mold. slurry, and then put the wax model into the floating sand machine to make the sand stick to the surface of the wax model, and repeat the actions of dipping slurry and sticking sand until a mold with a certain thickness is formed on the surface of the wax model, and then heated to melt the wax model and flow out, that is Make a mold into which molten metal can be cast. In the sand floating machine of the prior art, the blower is directly connected to the sand barrel, and the airflow blows to th...
