Abstract

PURPOSE:To obtain the said mouthpiece easily by a method wherein when a core block is fixed in a female mold a plate is penetrated so as to shield a passage between the core block and the female mold, the core block and the female mold are connected by this plate, the core block is hanged in the female mold and a great number of circular holes are penetrated scatteringly on the plate. CONSTITUTION:A core block b is provided with a symmetrically tapered portion 6, a smooth surface externding toward the other end along the axial direction and a projecting plate 4 extending rectangularly to the axis in the middle. On the other hand, the female mold a is divided into two portions, an outer front portion 1 and a base portion 5 along the projecting plate 4 and both these portions are connected with bolts 9 as the projecting plate 4 is put between them so that the core block 4 is hanged in the female mold. A great number of circular holes 8 are penetrated at intervals on the projecting plate part 4 facing the passage 7 provided between the female mold a and the core block b to obtain a mouthpiece for molding the resin tube body. Thus, it becomes to easy to adjust the flow of resin and to mold the tube body.
