  • Patent number: 11911820
    Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.

  • Patent number: 9962870
    Abstract: An injection molding machine includes first and second injection units. When it is detected that the first injection unit malfunctions, information that notifies the other injection unit (that is, second injection unit) the fact that the first injection unit is malfunctioning is outputted. The second injection unit that has acquired the malfunction information from the first injection unit carries out a malfunction process based on a preset malfunction process setting corresponding to other-injection-unit malfunction information.
