The embodiment of the utility model provides an in, be sealing area through setting up hot bent district 200, can reduce the heat in the hot bent district 200 and scatter and disappear, keep the heat degree in the hot bent district 200, can also set up the forced air cooling in last lower mould district 100, keep last lower mould district 100 to be in the cooling to dispel the heat to the mould, and set up sealing area and can effectively prevent scattering and disappearing of protective gas in the hot bent processing production of needs protective gas, have the practicality. Through the arrangement of the movable door 500, on one hand, heat dissipation in the hot bending area 200 can be prevented, and on the other hand, the upper die 300 and the lower die 400 can conveniently enter and exit the upper die area 100 and the lower die area 200, so that the production efficiency is improved. The movable door 500 can be vertically arranged, the control mechanism controls the movable door 500 to move upwards to open, and controls the movable door 500 to move downwards to close; the movable door 500 may be laterally disposed, and the control mechanism controls the movable door 500 to move outward to open and controls the movable door 500 to move inward to close. In other embodiments, a movable door 500 may be disposed between the upper and lower mold sections 100 and 200, and the side of the upper and lower mold sections 100 away from the hot bending section 200 is opened to facilitate the movement of the upper mold 300 and the lower mold 400 into the upper and lower mold sections 100.
