A brake control method for an injection molding machine includes the steps of obtaining mold clamping force information indicating the mold clamping force of a mold opening/closing mechanism and determining whether or not the mold clamping force of the mold opening/closing mechanism exceeds a predetermined value, based on the mold clamping force information. When the mold clamping force of the mold opening/closing mechanism does not exceed the predetermined value and when a servo amplifier cuts off the supply of power to a servomotor that drives the mold opening/closing mechanism, a brake mechanism for applying braking force to the mold opening/closing mechanism is actuated. On the other hand, when the mold clamping force of the mold opening/closing mechanism exceeds the predetermined value, the brake mechanism will not be actuated.

A toggle mold closure assembly for injection presses includes: fixed, mobile and reaction planes, mounted on columns; a control unit of the toggle, having four pairs of levers, arranged symmetrically at two sides, in upper and lower parts of the structure, interconnected by a pin and to the reaction plane and mobile plane by respective pins; and an actuation unit of the control element. The control unit is placed on the axis of the toggle in the middle of the pairs of main side levers, which have an outward movement. The control unit is connected, by control connecting rods, to the levers of the toggle connected to the reaction plane, and is placed between the central connection pin of the levers and the reaction plane. The control unit is provided with heads for connection to the connecting rods external to the reaction plane and turned towards the reaction plane.

An injection molding machine capable of opening/closing a movable mold relative to a stationary mold by moving a crosshead backward and forward to move a movable platen backward and forward relative to a stationary platen through a toggle link. The injection molding machine includes a reciprocating mechanism that receives a counterforce exerted on the crosshead in the back-and-forth direction when the movable mold and the stationary mold are closed, and a load acquisition unit that acquires a load exerted on the reciprocating mechanism in a direction perpendicular to the back-and-forth direction of the crosshead.

An injection molding machine includes: a moving platen connected to a rear platen via a toggle link and configured to be moved closer to and away from a stationary platen; a guide rod support provided between the rear platen and the moving platen, and configured to support a guide rod for guiding a cross head of the toggle link; a safety rod fixed to the moving platen and extending toward the guide rod support; and a safety latch provided on the guide rod support and configured to restrict movement of the moving platen by engagement with the safety rod.

The present invention relates to a position determining mechanism for a rotary platen. The rotary platen is disposed to face a mold platen and is provided to be rotatable with respect to the mold platen. The position determining mechanism includes a position determination part which is provided to one platen of the mold platen and the rotary platen, and a position determination driving mechanism which is provided to the other platen, in which the position determination driving mechanism includes a press member and a pressing device, and when the press member is pressed by the pressing device and the press member is fitted into the position determination part, a rotation position of the rotary platen is determined.
