Abstract: An injection molding machine includes a connection member that connects a nozzle touch mechanism and a fixed platen. The connection member has: an arm part that rises upward from a support frame part on a side of the fixed platen; and a platen connection part that is provided on an upper section of the arm part and serves as a second connection section connected to the fixed platen. The platen connection part has: a connection pin that is fixed to the arm part and extends in a left-right direction coinciding with the width direction of a machine frame; and a rotary member that is fixed to the fixed platen and can rotate around the connection pin, wherein the connection pin is disposed so as to pass through the center axis of a nozzle and include a plane parallel to a mount surface of the machine frame.

Abstract: A mold clamping mechanism includes a seal member for sealing in lubricant that has leaked from a through-hole, attached to a peripheral side surface of a tie bar exposed from the moving platen, and a housing that is separate from the moving platen, contacts a surface of the moving platen, and covers the tie bar, from the moving platen to the seal member, and the seal member.

Abstract: A bracket is disposed on both side surfaces of both ends of each of a rear platen side rail and a movable platen side rail. The bracket includes a screw hole. When an adjustment bolt is tightened, the adjustment bolt presses the rear platen side rail or the movable platen side rail. A rear platen and a movable platen are aligned to each other by finely adjusting the directions of the rear platen side rail and the movable platen side rail.
