referring to fig. 1 to 3, the utility model discloses a cabin body mold, including mold body 1, mold body 1 is used for the shaping of the cabin body. Set up in 1 diapire of mould body and place chamber 2, place 2 interior interference fit of chamber and have piston plate 3, piston plate 3 and place and be provided with the first spring 4 of a plurality of between the diapire in chamber 2. One side of the die body 1 is provided with a pneumatic part 5, and the pneumatic part 5 is communicated with the lower half part of the placing cavity 2.

The pneumatic part 5 comprises an air pump 51, and the air pump 51 is fixedly connected to the side wall of the mold body 1. One side of the die body 1 is provided with a three-way valve 52, and the output end of the air pump 51 is communicated with the input end of the three-way valve 52. One of the output ends of the three-way valve 52 is communicated with the lower half part of the placing cavity 2 through a pipeline. A heat dissipation cavity 53 is formed in the side wall of the die body 1, one end of the heat dissipation cavity 53 is communicated with the other output end of the three-way valve 52, and the other end of the heat dissipation cavity 53 is communicated with the outside of the die body 1.

The three-way valve 52 is adjusted to open one of the output ports, and the air pump 51 is operated to blow air into the placing chamber 2 or into the heat dissipation chamber 53.

The heat dissipation cavity 53 is arranged spirally downwards around the die body 1, and the gas can fully move in the die body 1. The semiconductor refrigerating sheet 12 is arranged in the heat dissipation cavity 53 and close to the three-way valve 52, and the semiconductor refrigerating sheet 12 works to reduce the temperature in the placing cavity 2, so that the cooling forming efficiency is further improved.

The top of the piston plate 3 is fixedly connected with a plurality of second springs 6, the top of each second spring 6 is fixedly connected with a push rod 7, and the elasticity of the plurality of second springs 6 is different. Slide hole 8 has been seted up to the position that the diapire corresponds push rod 7 in mould body 1, and push rod 7 first sliding connection is in corresponding slide hole 8, and the clearance between push rod 7 and the slide hole 8 is less, and cabin body raw materials can not get into.

When the first spring 4 and the second spring 6 are both in a natural state, the top surface of the push rod 7 is coplanar with the bottom wall in the die body 1. Blowing air towards the inner lower half part of the placing cavity 2 to drive the piston plate 3 to move upwards, stretching the first spring 4, driving the second spring 6 and the push rod 7 to move upwards by the piston plate 3, pushing the bottom of the cabin body by the push rod 7, and enabling the cabin body to be separated from the die body 1, wherein the push rods 7 have different thrusts due to different elastic forces of the second springs 6.
