Abstract
PURPOSE: To prevent the bubbles from being generated and eliminate the cause of the reduction in strength by a method wherein through-holes are provided at the upper end parts of the female mold corresponding to the parts where the shape of the molding changes sharply.
CONSTITUTION: When a resin such as polyester is poured into the cavity through a pouring hole 10 opened in the female mold 1, the resin layer b penetrates rightward and leftward so as to sandwich a glass fiber mat 8 interposed between the molding surfaces 5. Due to the pressure of the resin, the air present between the molding surfaces 5 is forced outwards through the mat 8 held between the mat-nipping portion 9 and the molding surface 5 facing thereto. The poured resin such as polyester flows into small recesses 7, irrespective of the presence of the portions where the shape of the molding changes sharply, and the air is discharged via the through-holes 3 instead of remaining in the recesses 7. After the overflow of the poured resin is confirmed, the through-holes 3 are plugged 12.
