Ultrasonic washing type sand removal head of casting mold

Abstract

The invention relates to an ultrasonic washing type sand removal head of a casting mold. The ultrasonic washing type sand removal head of the casting mold comprises a fixed base. A lifting air cylinder is installed on the upper surface of the fixed base. A plurality of ejector cores are installed on the lower surface of the fixed base. The ejector cores correspond to sand shooting holes in position. The fixed base is of a hollow structure provided with an inner cavity. A water inlet pipe communicated with the inner cavity of the fixed base is installed on the upper surface of the fixed base. Each ejector core is of a hollow pipe structure provided with a water guiding channel, wherein a plurality of jet holes which are communicated with the water guiding channel and arranged with one above another are formed in the side wall of the ejector core, and the jet holes are obliquely arranged downwards relative to the central axis of the ejector core. Ultrasonic generation pipes are installed in the water guiding channels. Each ultrasonic generation pipe comprises an emitting end and a guiding-in end. The emitting ends penetrate through the fixed base to be arranged in the water guiding channels. The guiding-in ends are fixedly connected with sealing covers at the lower ends of the ejector cores. The lower ends of the emitting ends are in electric contact with the upper ends of the guiding-in ends.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to the cleaning technology of casting moulds. Background technique [0002] At present, many castings are covered with iron mold sand, and the coated sand is generally made of phenolic resin, which will collapse at high temperature and fall off the mold automatically by the weight of the sand, but for the sand in the sand shooting hole of the iron mold, Relying on its own weight, it cannot completely fall off, so manual cleaning is required later, so the labor intensity is relatively high, and the production cost will also increase accordingly, and manual cleaning will inevitably cause omissions. At present, the mechanical cleaning device that has appeared uses the top core to be inserted into the sand shooting hole to drop the sand from the mold. This method requires the top core to be in contact with the inner wall of the sand shooting hole. The pressure will cause some damage to...

[0002] At present, many castings are covered with iron mold sand, and the coated sand is generally made of phenolic resin, which will collapse at high temperature and fall off the mold automatically by the weight of the sand, but for the sand in the sand shooting hole of the iron mold, Relying on its own weight, it cannot completely fall off, so manual cleaning is required later, so the labor intensity is relatively high, and the production cost will also increase accordingly, and manual cleaning will inevitably cause omissions

At present, the mechanical cleaning device that has appeared uses the top core to be inserted into the sand shooting hole to drop the sand from the mold. This method requires the top core to be in contact with the inner wall of the sand shooting hole. The pressure will cause some damage to the inner surface of the sand shooting hole, thus affecting the normal use of the mold
