Abstract
The utility model relates to a spiral water-cooling cooling structure of an eccentric shaft sleeve in a conical sand making machine. The cooling structure comprises a lower case of a conical sand making machine, wherein spiral grooves are formed in the excircle face of an eccentric shaft sleeve in the conical sand making machine; the excircle face of the eccentric shaft sleeve tallies with the inner wall of a main shaft assembling shaft hole to form spiral water-cooling cavities; water inlet and outlet grooves are vertically formed in the inner walls of the main shaft assembling shaft hole and are respectively communicated with the spiral water-cooling cavities; a water inlet hole is formed in the upper part of the water inlet groove and is communicated with a water inlet pipe; a water outlet hole is formed in the lower part of the water outlet groove and is communicated with a water outlet pipe. The cooling structure has the advantages that the eccentric shaft sleeve continuously carries out conduction cooling on inner and outer copper sleeves of a main shaft and the main shaft, thus reducing the operating temperatures of the inner and outer copper sleeves of the main shaft and the main shaft, ensuring that the temperature rise of tin in the materials forming the inner and outer copper sleeves of the main shaft can not exceed the melting point of tin, avoiding honeycomb structures of the inner and outer copper sleeves of the main shaft and then preventing the inner and outer copper sleeves of the main shaft from being fractured and broken and the sand making machine from failing to operate.
