ABSTRACT:
The present invention relates to a mass production device for ice carvings mainly for the automatic production of ice carvings. The invention has a conveyor belt, molding dies, a cooling water tank, a freezing mixture tank, a boring device, an injection device, a temperature rising device and a stripping device. Filtered and cool water is poured into the dies, and the dies delivered into a freezing mixture tank through the conveyor belt for freezing the surface of water in the dies first. A boring hole is used for injection of coloring liquid and decorative objects to be embedded in the frozen carvings. When the dies exit from the freezing mixture tank, they enter a temperature rising device to slightly raise their temperature to facilitate removal of the dies by means of hydraulic cylinder of the stripping device. Ice carvings are thus accomplished through automatic production.
