METHOD FOR PRESSURE MOLDING OF RESIN MOLDING PRESS

摘要

PURPOSE:To mold a molded item with a high quality always even though there exists fluctuation in viscosity of a molding material by performing the operation under a condition where specified ranges of allowance are provided to each final mold clamping position and press output when press molding is performed in a resin molding press. CONSTITUTION:After a slide 5 and a bed 4 are each provided, a molding material such as a sheet-like composite resin and a sheet-like engineering resin is placed between a top mold 8 and a bottom mold 9 and the rigid slide 5 is moved slidingly toward the bed 4 part below by actuating several pressurizing cylinder 6 provided in parallel in a crown 2 part to press-mold a molding material 11. in such the resin molding press as this, a specified range of allowance is provided as a final mold clamping position for pressing and a required width for adjustment is provided to the output of the pressing cylinder in such a way that the mold is closed at the final mold clamping position of this specified range of allowance. It is thereby possible to cope flexibly with the situation even if there exists fluctuation in viscosity of the molding material.
