    • The present invention has an object of eliminating the holding pin trace of a composite-molding of the dichromatic molding by refilling with resin by the pushing pin and preventing the lateral-shift of the primary molding during the refilling. It is made possible to fill closed recess and cavity with resin through a communicating hole formed in the primary molding by the pushing pin. A primary cavity mold 11 and a secondary cavity mold 12 are juxtaposed at symmetrical positions of a fixed plate 1. Core molds 14 closing alternately with both thereof are juxtaposed on a rotary table 7 installed on a movable platen 4. Holding pins 15 of the primary molding 30 and a resin pushing pin 16 are installed in the core mold 14 in a way to appear and disappear in respect to a cavity. The primary molding 30 is held in contact with the surface of the secondary cavity mold by the holding pin 15. A pin hole 20 for refilling resin is formed to be opened on a surface of the core mold by retracting the pushing pin 16. A secondary cavity including the pin hole 20 is refilled with a different material resin by injection. The holding pin 15 is retracted and sunk in the surface of the cavity mold. The pushing pin 16 is moved forward to force the resin for refilling the pin hole 20 into the resin in the cavity. The regions not filled with resin due to the holding pin 15 are refilled up.
    • 本发明的目的是通过用推脂销填充树脂来消除二色成型件的复合成型的保持销迹线,并防止在再填充期间初级成型件的横向偏移。 通过推模形成在一次成型体中的连通孔,可以将树脂密闭的凹部和腔体填充。 主腔模11和次腔模12并置在固定板1的对称位置。 与其两者交替关闭的芯模14并置在安装在可动台板4上的旋转台7上。 一次成型体30的保持销15和树脂推压销16以相对于空腔出现和消失的方式安装在芯模14中。 主模30通过保持销15与二次模模的表面保持接触。 通过缩回推压销16,在芯模的表面上形成用于再填充树脂的销孔20。 包括针孔20的次级腔通过注射再填充不同的材料树脂。 保持销15缩回并沉入空腔模具的表面。 推动销16向前移动以迫使树脂将针孔20再填充到空腔中的树脂中。 由于保持销15而不填充树脂的区域被再填充。
