Non-time dependent calculated variables based on measured strain are used to effectively determine an optimal hold profile for an expanding crosslinking polymer part in a mold cavity. A system and/or approach may first inject molten expanding crosslinking polymer into a mold cavity, then measure strain at the mold cavity or at another location within the injection molding system, and then calculate at least one non-time dependent variable during an injection molding cycle. Next, the system and/or method commences a hold profile for the part, and upon completing the hold profile, the part is ejected from the mold cavity, whereupon a cure profile is commenced.

An operation setting device includes a first step of inputting an operation sequence and an operation position of the ejector by touching a desired point in a graph displayed on the setting display screen, a second step of inputting operation parameters including an operation speed, an operation position, an operation time, and an operation pattern of the ejector on the basis of the operation position thus input, and a third step of displaying in the graph and numerically displaying in a numerical value display part of the setting display screen the operation position and the operation parameters thus input. The operation position and operation parameters for each operation set in the first step to the third step are displayed in the graph and numerically displayed in the numerical value display part.

Provided is an injection molding system that uses an identification code, collectively manages the specifications and combinations of an injection molding machine and peripheral devices, and secures a suitable production state for a combination of a wide variety of specifications. An injection molding system include: an injection molding machine; a plurality of peripheral devices; an identification code attached to the injection molding machine and each of the plurality of peripheral devices, and having identification information of the injection molding machine and each of the plurality of peripheral devices; a code reader that reads the identification code; and a management unit including a storage unit that stores a correct combination of the identification code of the injection molding machine and the plurality of peripheral devices, and a confirmation determination unit for confirming whether the correct combination stored in the storage unit matches the identification code read by the code reader.

A system for programming a protection device for a molding machine includes a controller for actuating a plurality of molding machine actuators in an actuation sequence, each distinct actuation constituting a respective machine component actuation of an associated machine component. An HMI is operable to: present a GUI specific to a chosen machine component actuation; and for each of a plurality of other machine component actuations, define within the GUI, based on operator input, a rule specifying a state of the chosen machine component actuation relative to a state of the other machine component actuation for preventing interference between the two machine component actuations. The controller is configured, based on the rules defined within the GUI, to trigger an action, upon violation of any one of the rules, for reducing a risk of interference between the chosen machine component actuation and a respective one of the other machine component actuations.

A molding machine includes: a mold that forms a molded product; an extrusion pin that transmits to the molded product an extrusion force for demolding the molded product from the mold, wherein the extrusion pin is inserted in the mold; and a control device configured to control the extrusion force of the extrusion pin. The control device controls the extrusion force at a first timing elapsed a first elapsed period so as to be greater than the extrusion force at second timing elapsed a second elapsed period. The first elapsed period is an elapsed period from a predetermined start point. The second period is an elapsed period from the start point and a shorter than the first elapsed period.

There is disclosed a method (400) of ejecting a molded article (310, 312) from an injection mold (100). The method (400) comprises: during a second portion of the mold opening cycle of the injection mold (100), the second portion occurring later in time relative to a first portion of the mold opening cycle of the injection mold (100): controlling velocity of at least one of: (i) the moveable mold half (102, 502) relative to the stationary mold half (104, 504), (ii) the ejector (230) relative to the moveable mold half (102, 502); and (iii) an ejector actuator linked to the core insert (112, 114, 512, 514); and (iv) a stripper actuator that is linked to the stripper sleeve (116, 516); the controlling executed such that the molded article (310, 312, 506) is ejected from the molding component with a substantially zero departure-velocity along the first axis of operation.
