| description | The utility model provides a low-pressure pouring mould with a pressure warning function. A first pressure relay and a second pressure relay are arranged on a first air pipe and a third air pipe respectively. The first pressure relay and the second pressure relay extend into the first air pipe and the third air pipe respectively. The first pressure relay and the second pressure relay are both provided with a normally open contact. The negative electrode of a battery of a buzzer is connected with a negative electrode line of the buzzer. The negative electrode of a battery of a second buzzer is connected with a negative electrode line of the buzzer. According to the structure, the defects that in the prior art, an upper mould body and a lower mould body are not combined tightly, so that the whole structure is complicated, the pouring effect of the upper mould body and the lower mould body is difficult to guarantee, and a device capable of warning an operator of the pressure of compressed air fed in the pouring process is not provided are overcome. |
