    • An injection molding system for forming a molded plastic part including a die having a pair of die halves which mate along their joining surfaces to form a parting line and define a mold cavity, a plurality of ejection pins within at least one of the die halves and operable to move the finished molded part in a direction away from at least one of the die halves, a gate removably mounted to one of the die halves, and a runner. The gate includes an inlet and an outlet having an edge surface extending in a direction generally opposite to the movement of the molded part upon ejection from the mold cavity. Upon separation of the two die halves, the ejection pins are then further operable to remove excess cooled plastic material from the gate and the runner.
    • 一种用于形成模制塑料部件的注模系统,所述模制塑料部件包括具有一对半模的模具,所述模具沿其接合表面配合以形成分型线并限定模腔,所述模具半部中的至少一个中的多个喷射销和 可操作地使成品模制件沿远离至少一个模具半部的方向移动,可移除地安装到模具半部之一的浇口和流道。 所述门包括入口和出口,所述入口和出口具有在与所述模腔排出时沿大致与所述模制部件的运动相反的方向延伸的边缘表面。 在分离两个半模时,喷射销然后可进一步操作以从浇口和流道移除多余的冷却塑料材料。
