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).
摘要:
Disclosed, amongst other things, is a method of post-mold cooling of a molded article, the molded article having just been molded within mold halves, the method comprising: receiving, in a post-mold device, the molded article; subjecting the molded article to post-mold cooling, the post-mold cooling including: implementing a first post-mold cooling process portion in the post-mold cooling device at a first temperature; and implementing a second post-mold cooling process in the post-mold cooling device portion at a second temperature, said second post-mold cooling temperature being greater than said first post-mold cooling temperature; determining a switch point; triggering at the switch point, a transition from the first post-mold cooling process portion to the second post-mold cooling process portion.
摘要:
A mold-tool system (100), comprising: a melt splitting device (102) being configured to interact with a melt distribution device (105), the melt splitting device (102) having: a single inlet (106); multiple outlets (108) being set apart from the single inlet (106), the multiple outlets (108) being configured for fluid communication with the melt distribution device (105); and uninterrupted melt channels (110) extending from the single inlet (106) and the multiple outlets (108).
摘要:
There is provided a method (300) of controlling melt pressure at a filter outlet (113) of a melt filter (112) in an injection unit (100) having an extruder (102) that is connectable to a melt accumulator (122) via the melt filter (112), the melt filter (112) being associated with a target melt pressure range, the method executable at a controller (126) associated with the injection unit (100), the method (300) comprising: appreciating (310) an indication of an actual melt pressure associated with the melt filter (112); responsive to the actual melt pressure not being within the target melt pressure range, determining (320) a remedial parameter that is instrumental in bringing the actual melt pressure within the target melt pressure range; releasing (330) a control signal to execute an action associated with the remedial parameter, thereby causing the actual melt pressure to fall within the target melt pressure range.
摘要:
A method (300, 400) of controlling a melt preparation device (102, 110) is provided. The melt preparation device (102, 110) is located upstream from a melt accumulator (122), the melt accumulator (122) and the melt preparation device (102, 110) being part of an injection unit (100) for preparing and injecting molding material and being associated with a target cycle time. The method (300, 400) comprises appreciating (310, 410) an operational parameter associated with the melt accumulator (122); appreciating (320, 420) a target performance indicator associated with operation of the injection unit (100); based on a comparison of the operational parameter to the target performance indicator, generating (330, 430) a control signal for controlling operation of the melt preparation device (102, 110), such that the melt preparation device (102, 110) prepares molding material in an amount sufficient to transfer to the melt accumulator (122) within an allocated portion of the target molding cycle time.
