    • A molding die (10) includes an upper die (12), upper-die pins (24) arranged in the upper die to be movable up and down, springs (30) arranged in the upper die to urge the upper-die pins downwardly, a lower die (11), lower-die pins (44) arranged in the lower die to be movable up and down and springs (30) arranged in the die to urge the pins upwardly. In molding, a hollow primary molded piece (45) is accommodated in a cavity (50) defined by the upper die and the lower die. Then, the piece is mounted on the pins with retained apart from a concave bottom surface of the lower die. Before closing the molding die, it is started to inject molten resin into the cavity. As a result, the molten resin enters a space between the primary molded piece and the concave bottom surface of the lower die. Even after completing to close the molding die, the injection of the molten resin is continued.
    • 一种模制的(10)包括在所述上部(12)上部的上部(24),其布置引脚为可上下移动,在上部布置的弹簧(30),其向下推动上部销 ,低级的(11)下的销(44)在布置在下部的是可上下移动,并在管芯布置的弹簧(30)向上推动销。 在成型,中空一次成形品(45)被容纳在由上限定的腔体(50)和所述的下部。 然后,将片被安装在销从下部的凹底表面保持分开。 前关闭其,它开始熔化的树脂注入到腔中的成型。 其结果是,熔融树脂进入一次成形品和下的凹状的底部表面之间的空间。 即使在完成关闭该熔融树脂的注入继续进行成型。
