There is provided a control system for an apparatus for taking out a molded product, the apparatus performing appropriate operation when a collision occurs while a servo system control section is manually operated. When a collision detection section outputs an operation stop command, a deviation clearing section performs clearing operation to bring deviations in a servo system control section to zero with the servo system control section kept on. Positioning is completed as the deviations are brought to zero, which enables operation to be performed again. When a retracting operation is performed after the operation is stopped, servomotors are operated according to an operation command, which allows smooth retraction from the collision state.

An injection molding machine includes: a timing belt wound around a driving-side rotation member and a driven-side rotation member and configured to transmit power from the driving-side rotation member to the driven-side rotation member; a driving-side rotation detecting unit configured to detect a rotational speed of the driving-side rotation member; a driven-side rotation detecting unit configured to detect a rotational speed of the driven-side rotation member; and an abnormality detecting unit configured to detect an abnormality in the timing belt based on a relative speed difference between the rotational speed of the driving-side rotation member detected by the driving-side rotation detecting unit and the rotational speed of the driven-side rotation member detected by the driven-side rotation detecting unit in a predetermined period after the driving-side rotation member starts to rotate from a stopped state.

A method to predict the remaining useful life of a plasticizing screw for an injection molding machine is provided. The method comprises: creating an energy-pressure ratio distribution estimate for normal operation of the screw for a mold; creating a temporally local energy-pressure ratio distribution estimate from real time data for the screw for the mold; comparing the local distribution with the distribution for normal operation; and generating an alert if the comparison of the two distributions predicts that the remaining useful life is negligible.

A vertical injection molding machine includes a mold clamping device configured to clamp a mold, an injection device provided on the mold clamping device, the injection device being configured to inject an injection material, a controller including an operation terminal, the operation terminal provided on an operation side of the vertical injection molding machine, and a safety fence surrounding other three sides of the vertical injection molding machine except for the operation side. Alight curtain and a cover are provided on the operation side. The light curtain includes a plurality of spaced light sources and the same number of light receiving sensors, the light curtain being configured to detect an entry into the mold clamping device from the operation side. The cover is disposed on or above the light curtain.

An insert molding includes a lithium-ion battery, temperature measurement element and a pressure measurement element disposed close to the lithium-ion battery to sense temperature and pressure around the lithium-ion battery during insert molding; and a molding resin that covers the lithium-ion battery, the temperature measurement element, the pressure measurement element and a cover member.

An injection molding machine includes: a mold clamping unit; an injection unit; and a safety cover that surrounds the mold clamping unit and the injection unit. The safety cover includes a detachable panel that is attached to an opening. The safety cover includes a door portion that moves between a position where the door portion blocks a second portion of the opening and a position where the door portion does not cover the opening. The safety cover has a size that is smaller than the opening but greater than the second portion. A detachable panel has a first stopper that restricts an opening motion of the door portion when only the second portion is open. The safety cover is provided with a second stopper that restricts the opening motion of the door portion when the opening is entirely open and the detachable panel is removed.
