されている。Thereafter, both members 44 and 46 return to their reference positions by the action of the servo motor, and as shown in FIG.
The air cylinder 52 supporting the frame member 46 extends and
Then, the heating plate 44 is integrally lowered from the reference position along the rail 42 and stops at a predetermined position above the silver mold 18. Along with this, the sheet is unwound by one pitch. Since the lower part of the frame member 46 is open, the frame member 46 can surround the silver mold 18, and the heating plate 44 can hold the sheet and heat the silver mold 1.
Close cavity 8. At this time, the pattern on the sheet is placed at a regular position (synchronization position II) with respect to the molding surface of the silver mold.

シートを極端に伸ばすことなく予備成形できる。In this state, first, the cavity of the female mold is evacuated through the ventilation hole 58 of the first mold 18. After that, the heating plate 44
The sheet 32 is peeled off from the surface of the heating section 44a by sending compressed air through the ventilation hole 50 of the sheet 32 as shown in FIG. It is attached to the molding surface of No. 18. In addition, in the case of deep tightening, that is, when the molding surface of the female mold is deep, the sheet can be removed by moving a part of the heating plate 44 toward the gate-shaped molding surface side while holding the sheet with a cylinder (not shown) and vacuuming. Can be preformed without excessive stretching.

On the other hand, according to the former method, no air remains in the special female mold for forming the sheet, so there is no need to provide a large number of ventilation holes. Therefore, it is possible to reduce the number of traces of ventilation holes that occur on the surface of the molded product.
