[0002] A thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside. According to the production process, it can be divided into tube cutting, bulging, segmentation, spinning, bottom cutting, cleaning and drying, etc. The spinning process is an advanced processing technology with little or no cutting that combines the process characteristics of forging, extrusion, stretching, bending, ring rolling, cross rolling and rolling. It is widely used in the processing and forming of rotating parts.

A sliding block 304 is fixedly connected, and the chassis 3 is slidably connected to the connecting rod 303. A connecting rod 1 308 is fixedly connected to the bottom outer wall of the connecting rod 303. Two connecting rods 1 308 are fixedly connected through a connecting rod 2 309, one end of one connecting rod 1 308 is fixedly connected to a rack 311, and one end of the other connecting rod 1 308 is slidably connected to a receiving tube 314.

A one-way valve 310 is fixedly assembled on the end of the reflux pipe 307 away from the gear 313, and the reflux pipe 307 is fixedly connected to the liquid inlet pipe 305 through the one-way valve 310.

[0022] According to the above structure, cooling liquid is connected to the liquid inlet pipe 305. When the sleeve mold 1 is moved downward by the downward pressure of the tail top of the spinning machine, the external pipe 103 is engaged with the injection pipe 306, and the external pipe 2 101 is engaged with the return pipe 307.
