Abstract
The present invention provides a molding apparatus by which it is possible to make a frame located around a mold contact thermoplastic resin. In the molding apparatus of the present invention, the thermoplastic resin extruded from an extruding machine in a sheet form is adsorbed onto a cavity surface of the mold. As a result, the thermoplastic resin is shaped into a shape according to the cavity surface. The molding apparatus includes a frame that is positioned around the mold and is movable relative to the mold. In the frame, a suction part to suck the thermoplastic resin is provided.
Claims16
A molding apparatus that adsorbs thermoplastic resin extruded in a sheet form from an extruding machine, onto a cavity surface of a mold, and shapes the thermoplastic resin into a shape according to the cavity surface, comprising a frame that is positioned on a perimeter of the mold and is movable relative to the mold, wherein
- a suction part for sucking the thermoplastic resin is provided in the frame.
A molding method, comprising:
- a sucking step in which air is sucked in from a suction part provided in a frame positioned on a perimeter of a mold so as to adsorb thermoplastic resin extruded from an extruding machine in a sheet form onto the frame, and to bond the thermoplastic resin to the frame;
- and
- a shaping step in which the thermoplastic resin facing a cavity surface of the mold is adsorbed onto the cavity surface, to shape the thermoplastic resin into a shape according to the cavity surface.
