Abstract

The present invention prevents breakage of a moving actuator of a movable die board relative to a stationary die board in a die clamping device for an injection molding machine. A die clamping device is provided with a movable die board moving means for bringing a movable die board (3) close to / away from a stationary die board (2) in the horizontal direction, the movable die board moving means comprising: an actuator (41) for moving / driving the movable die board (3); a clevis pin for connecting a tip end of an actuation rod (42) of the actuator (41) with the movable die board (3); a clevis pin fixing member for supporting the central shaft of the clevis pin in the direction perpendicular to the moving direction of the movable die board and fixing the clevis pin to the movable die board; and a clevis pin connection member for connecting the actuator and the clevis pin. The clevis pin connection member has a support structure rotatable by the clevis pin and is supported by the movable die board via the clevis pin fixing member, and the clevis pin, the clevis pin connection member, and the tip end portion of the actuator are arranged in series.

Description

technical field [0001] The invention relates to a mold plate opening and closing device of an injection molding machine, in particular to a connection mechanism between an action end of an actuator capable of driving a movable mold plate forward and backward and a movable mold plate. Background technique [0002] Conventionally, in the mold plate opening and closing mechanism of the injection molding machine, as described in Patent Document 1 and Patent Document 2, hydraulic or electric actuators are directly fixed to the movable mold plate and the fixed mold plate. or as Figure 16 , Figure 17 As shown, the connection between the movable mold plate and the actuator consists of a pressing member 61 mounted on the movable mold plate 3 and an actuator 41 having a groove portion that engages with the pressing member 61 in an engaging manner. 42, the pressing member 61 and the front end 45 of the operating rod 42 of the actuator 41 are connected with a slight gap S1, S2.
