Flip thermoforming machine

Abstract

The invention discloses a turning hot-pressing molding machine which comprises a rack, an upper mould heating plate, a lower mould heating plate, an upper mould lifting mechanism, a lower mould lifting mechanism and a hot-pressing mould, wherein a clamping turning device is arranged on the rack, and comprises a driving clamping turning structure and a driven clamping and turning structure; the driving clamping turning structure comprises a rotary bracket, a turning wheel rotatably mounted on the rotary bracket, and a clamping air cylinder fixed on the turning wheel and rotating along with the turning wheel; the clamping air cylinder is provided with a piston rod, and a driving clamping part is arranged at the front end of the piston rod; the driven clamping and turning structure comprises a fixed side plate, and a driven clamping part rotatably connected onto the fixed side plate; the clamping air cylinder is arranged between the fixed side plate and the turning wheel; the ejection direction of the piston rod faces the driven clamping part; a space in which the hot-pressing mould is clamped and turned is defined by the driven clamping part and the driving clamping part; the clamping turning device further comprises a driving mechanism for driving the turning wheel to rotate. According to the invention, the design is ingenious, the structure is compact, and the hot-pressing mould can be clamped and turned.

Description

technical field [0001] The invention relates to a silica gel hot-pressing forming machine, in particular to an overturning hot-pressing forming machine with a holding and overturning device. Background technique [0002] In the production of silicone prosthetic breasts, silicone bras or silicone breast pads, after the silicone gel is packed into a film bag and sealed, it needs to be cured and shaped by a hot pressing mold. At present, high-grade prosthetic breasts are filled with lightweight silica gel, that is, light polymer microbeads are mixed in the silicone gel to further reduce the specific gravity of the silicone gel composition. However, when this kind of silicone gel filled with light polymer microbeads is made by a traditional thermocompression molding machine, the light polymer microbeads will float up during the molding and heating molding process, resulting in the failure of the cured silicone product. The overall specific gravity is not uniform, resulting in t...

However, when this kind of silicone gel filled with light polymer microbeads is made by a traditional thermocompression molding machine, the light polymer microbeads will float up during the molding and heating molding process, resulting in the failure of the cured silicone product. The overall specific gravity is not uniform, resulting in the defect that the appearance, elasticity and hand feel of the product are poor locally
