[0028] Specifically, by connecting the cooling cavity 220 on the two mould seats 200 through the connecting pipe 231, the external water source is injected into the cooling cavity 220 of one mould seat 200, and then flows out from the cooling cavity 220 of the other mould seat 200, so that the water flow can flow between the two mould seats 200 to reduce the temperature with less pipeline, and the traditional multiple pipelines for water supply and drainage to different mould seats 200 are saved. By slidingly connecting the arc block 300 inside the cooling cavity 220, when the arc block 300 moves to the bottom of the cooling cavity 220, the water in the cooling cavity 220 can surround the outside of the mould cavity 210 in all directions, realizing the overall heat dissipation of the plastic bottle in the mould cavity 210 in the initial state. When the arc block 300 moves to the inside of the cooling cavity 220, the arc block 300 blocks the middle space of the mould cavity 210, so that the water in the cooling cavity 220 flows between the top and bottom of the mould cavity 210 through the communication groove 320 inside the arc block 300 to reduce the temperature, thereby realizing the key cooling of the bottle mouth and bottle bottom of the plastic bottle in the mould cavity 210.

[0029] As shown in Figure 2 In the embodiment, the top of the machine table 100 is fixed with a control box 110, and two air cylinders 111 are fixedly installed on the outside of the control box 110.
