Fixture for thermoplastic forming of special-shaped film

The utility model provides a clamp for thermoplastic molding of a special-shaped film. The clamp comprises a clamp bottom plate and a clamp top plate, a protrusion is arranged on the upper surface of the clamp bottom plate. A groove is formed in the lower surface of the clamp top plate; the bulge is matched with the groove; the clamp bottom plate is connected with the clamp top plate through bolts. According to the clamp, the protrusions are arranged on the clamp bottom plate, the grooves are formed in the clamp top plate, the structures of the protrusions are matched with the structures of the grooves, the protrusions correspond to the shapes of the two faces of the supporting film, and it is guaranteed that the shaped supporting film structure meets the use requirement. The clamp is low in cost, easy to use and stable in clamping, plastic can be heated and softened only in the low-temperature environment of 80 DEG C, the thin film can be molded to work, and the thickness of the thin film cannot be changed.
