## 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.

## Claims

### Claim 1

A hollow ice-making forming mould, comprising an inner membrane (1) which is in a fixed shape after being charged with 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 (1, 2) are hermetically connected with the base plate (3) respectively, a cavity (6) for pouring cooling liquid is formed between the inner and outer membranes (1, 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) in a detachable way. A zipper (21) is disposed on the outer membrane (2) to allow conveniently opening the outer membrane (2).

### Claim 2 (depends on 1)

The hollow ice-making forming mould of claim 1, wherein: a waterproof membrane is arranged at a back of the zipper (21).

### Claim 3 (depends on 1)

The hollow ice-making forming mould of claim 1, wherein: an air inlet (41) is disposed at bottom of the air filling and water injecting member (4) to connect to the air cavity (5), the air inlet (41) is provided with a switch to control its open and close.

### Claim 4 (depends on 1)

The hollow ice-making forming mould of claim 1, wherein: at least one liquid inlet (42) is provided on one side of the air filling and water injecting member (4) where the member is connected to the mould cavity (6).

### Claim 5 (depends on 1)

The hollow ice-making forming mould of claim 1, wherein: the base plate (3) is a metal base plate.

### Claim 6

A usage of a hollow ice-making forming mould, comprising the following steps:
1) filling air to an air cavity (5) formed by an inner membrane (1) and an base plate (3) through an air filling and water injecting member (4), closing an air inlet (41) when the shape of the inner membrane (1) is fixed, and using the air-filled inner membrane (1) as a mould core;
2) connecting an outer membrane (2) and the air filling and water injecting member (4), and closing a zipper (21);
3) injecting the to be molded cooling liquid into a mould cavity (6) between the inner membrane (1) and the outer membrane (2) through the air filling and water injecting member (4), until the shape of the outer membrane (2) is fixed under an effect of liquid tension;
4) placing the liquid filled mould into a cooling environment;
5) detaching the connection part between the outer membrane (2) and the air filling and water injecting member (4) after the liquid becomes a molded ice, then unzipping the zipper (21) of the outer membrane (2), releasing the air from the air cavity (5), disassembling the mould and removing the mould core to obtain the molded ice block.
