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 being configured to manufacture a molded article in a mold-cavity system by using a molding material, the molding system comprising:
a pressure-control system being coupled with the mold-cavity system; and a controller operatively coupling to the pressure-control system, the controller having a controller-usable memory tangibly embodying a set of controller-executable instructions being configured to direct the controller, the set of controller-executable instructions including:
mold-unpack instructions, including instructing the controller to control the pressure-control system to reduce, after solidification, at least in part, of the molding material being located in a nub region of the mold-cavity system, internal pressure of the molding material received in the mold-cavity system while the mold-cavity system remains isolated from a stream of flowable-molding material, beyond any reduction of the internal pressure in the molding material resulting from cooling of the molding material, so that the reduction in the internal pressure of the molding material is enough to permit safe opening of the mold-cavity system while permitting safe extraction of the molded article from the mold-cavity system.
