Self-balancing hot runner with independent flow and pressure control |
摘要 |
A method for use in injection molding with the capability to have precise and adjustable control of the molten plastic flow when molding at least two nonÂidentical (i.e. with more than 50% difference in weight or form) or identical complex-shaped and intricate plastic parts at the same time, utilising a mold with at least two parting layers via a standard conventional injection machine. This invention incorporates the principle of having two valve pins in which their movements are back-to-back and can be independently opened and closed as controlled by stepper, servo or linear motors linked to a separate independent tool controller. The two valve pins are positioned at the floating half of the mold for sequential, stack or multi-layer mold with multiple cavities. |
