METHOD AND SYSTEM FOR OPERATING AN INJECTION MOLDING MACHINE

摘要

According to embodiments of the present invention, there is provided a method and system for operating an injection molding machine. For example, a molding system (100) to manufacture a molded article (103) in a mold-cavity system (200) by using a molding material (101) is provided. The system (100) including pressure-control system (126) coupled with the system (200); and controller (160) operatively coupling to system (126), controller (160) having controller-usable memory (162) tangibly embodying set of controller-executable instructions (500) to direct controller (160), including mold-unpack instructions (520), including instructing controller (160) to control system (126) to reduce, after solidification, at least in part, of material (101) being located in a nub region (214) of system (200), internal pressure of material (101) received in system (200) while system (200) remains isolated from stream of flowable-molding material, beyond any reduction of internal pressure in material (101) resulting from cooling of material (101), so that reduction in internal pressure of material (101) is enough to permit safe opening of system (200) while permitting safe extraction of article (103).

主权项

1. A molding system (100) being configured to manufacture a molded article (103) by using a molding material (101), the molding system (100) comprising:
a mold-cavity system (200) for forming, in use, the molded article (103); the mold-cavity system (200) including:
a primary parting line (224) defined between a cavity portion (210) and a neck portion 206 and;a secondary parting line (222) defined between the neck portion (206) and a top portion (204); a controller (160) operatively coupling to the a mold-moving actuator, the controller (160) having a controller-usable memory (162) tangibly embodying a set of controller-executable instructions (500) being configured to direct the controller (160), the set of controller-executable instructions including a mold open instruction (902) configured to:
cause initial separation of the top portion (204) and the neck portion (206) relative to the secondary parting line, while keeping the primary parting line un-opened, while maintaining at least some clamp force.
