Hollow Ice-Making Forming Mould and Usage Thereof

Abstract

A hollow ice-making forming mould comprises an inner membrane(1) which is in a fixed shape after charging air and an outer membrane (2) which is in a fixed shape after liquid injection and is disposed outside the inner membrane (1); a base plate(3) is arranged at the bottom of the outer membrane (2); the bottoms of the inner and outer membranes are hermetically connected with the base plate(3) respectively, wherein an airtight air chamber(5) is formed between the inner membrane (1) and the base plate(3), and a cavity(6) for pouring cooling liquid is formed between the inner membrane (1) and the outer membrane (2); an air filling and water injecting member(4) is provided at the top of the inner membrane (1); a top part of the outer membrane (2) is connected with an upper part of the air filling and water injecting member(4) by a detachable way. A usage of the mould comprises charging the air chamber(5) through an air inlet(41), closing the air inlet(41), connecting the outer membrane(2) and the air filling and water injecting member(4), injecting the liquid into the cavity(6) through an injection hole(42), disposing the mould in a cooling environment, detaching the connection between the outer membrane(2) and air filling and water injecting member(4), discharging the air of the air chamber and obtaining the molded ice block.
