  • Patent number: 11997440
    Abstract: Provided is a management device capable of communicating with a counting device that counts the number mold opening and closing cycles. The management device includes a memory and a processor. The processor outputs one or more index values that can be used for determining a next maintenance timing, by using a first value that is a count value acquired from the counting device, and one or more second values that are count values, at a last maintenance time, stored in the memory.

  • Patent number: 8033487
    Abstract: When the rocking side wall is to be opened, the rocking side wall is rotated about a shaft body and a cutout surface comes into contact with a side surface on the upper side of a connection plate When the rocking side wall is further opened with the cutout surface in contact with the side surface on the upper side of the connection plate, the rocking side wall is rotated about the shaft body in operative association with the connection plate. In the middle of the opening motion of the rocking side wall, a rocking axis of the rocking side wall moves from the shaft body to the shaft body. When the rocking side wall is rotated about the shaft body placed closer to the outside than the shaft body, the rocking side wall is opened while being further away from rough crush blades and the crush blades, and this widen the opening between the rocking side walls.
