A thermoplastic material sheet (note: it is not limited to a film-like material, but may also be a repulsive material such as a synthetic fiber woven fabric or a non-woven fabric) is fixed between both molds, and the middle mold d is heated. . Heating is medium sized d
Blow hot air from the air pipe mentioned above into the vent hole 1.
This is done by evacuation from 2. Needless to say, the degree of heating and the heating time are adjusted to the softening temperature of the adherend and the time required for molding. The above-mentioned adhered thermoplastic material sheet is thus molded into a hollow shape in the gaps 10 to 11 between the two molds. The materials of both molds do not necessarily have to be the same; for example, if the middle mold d is made of stainless steel and the outer mold e is made of a heat conductive light metal such as aluminum, the heat conduction to the material sheet that is the molded object will be improved. As a result, molding efficiency can be improved. In addition, the outer mold e
It is also possible to add a preheating device such as electric heating. The mold of the present invention has the following features: except that the middle mold d is hollow, the outer mold e is separable, and a predetermined gap 10 to 11 is secured between the two molds; In other words, there is no particular limitation on the shape of the middle mold d and the concave shape of the gap 10 component of the outer mold e. Therefore, the mold of the present invention can produce molded products of a wide variety of shapes and dimensions using a thermoplastic material sheet.
