    Abstract: A hydraulic mold clamping unit, in particular for an injection molding machines or a press, includes a fixed lower platen and an upper plated which is moved by an open-close mechanism in a vertical direction. The open-close mechanism includes at least one hydraulic cylinder of a first type having a double-acting piston, and at least one hydraulic cylinder of a second type. A hydraulic pump system is operatively connected to both sides of the hydraulic cylinder of first type, and a pressure accumulator is operatively connected to the hydraulic cylinder of second type. in order to realize an energy-efficient operation of the upper platen at little pressure build-up, a proportional or regulation valve is disposed in the pump system for modifying a back pressure in the hydraulic cylinder of first type, when closing the lower and upper platens.

    Abstract: A closure position detection mode is provided so as to obtain a rate of variation (which encompasses an amount of variation) in a physical quantity to a predetermined amount of movement of a movable platen or a crosshead, and detect, as a mold closure position, a position when the variation rate reaches a preset ratio. The mold clamping apparatus is previously operated in the closure position detection mode so as to store, as a reference value, the mold closure position at which a target mold clamping force is obtained. In production operation, the mold clamping apparatus is operated in the closure position detection mode so as to obtain an actual mold closure position (detection value). The mold clamping force is corrected on the basis of a deviation of the detection value from the reference value.

    Abstract: An electromechanical clamping device with hydraulic assistance. A thrust mechanism driven by an electric motor displaces two clamping jaws with respect to each other along a guide device. One clamping jaw is divided into two mutually displaceable part java. A chamber to hold pressure medium is formed between the part jaws. The first part jaw can be displaced along the guide device and locked with respect to the latter. One part jaw is provided with a first cylinder coupled to the output of the thrust mechanism. In order to close the clamping device, in a first step the thrust mechanism pulls the part jaws against the other clamping jaw, and in a second step the thrust mechanism delivers pressure medium from the first cylinder into the chamber between the two part jaws, with the first part jaw locked with respect to the guide device. To open the clamping device, in a first step a second cylinder arranged between the two part jaws pulls the part jaws against each other, with the first part jaw locked with respect to the guide device, and then in a second step the thrust mechanism forces the part jaw coupled to it in the opening direction, forcing the other part jaw with it, with the first part jaw unlocked from the guide device. The clamping device is provided for production machines, in particular for injection molding machines.

    Abstract: The invention relates to an electric injecting molder and an injection velocity and injection pressure controlling method for an electric injecting molder, and it is an object of the present invention to make it possible, in injection molding by an electric injection molder, to mold stable resin products having a minimized dispersion in the quality even if the operation environment varies. When an injection screw (23) disposed in an injection cylinder (22) is driven to move in forward and backward directions by an electric motor (29A) to inject resin material (3) in the injection cylinder (22) into a metal mold (1, 2) to fill the metal mold (1, 2), the electric motor (29A) is first velocity-controlled to fill the resin material (3) into the metal mold (1, 2), and, after the filling, the electric motor (29A) is pressure-controlled to replenish the resin material for shrinkage of the resin. Upon the velocity control, a velocity target value for the injection screw (23) is corrected in response to a force detection value so that the velocity target value for the injection screw (23) may decrease as the force detection value increases to perform velocity feedback control of the electric motor (29A) so that a velocity detection value from velocity detection means may be equal to the velocity target value.

    Abstract: A temperature regulator main body is connected to a cooling hole formed in a temperature regulating part under a hopper through a tube and comprises a tank for a cooling medium, a pump, a radiator, and a fan facing the radiator to send cold air and driven by a motor. By driving of the pump, the cooling medium circulates between the temperature regulating part under the hopper and the temperature regulator main body. A temperature sensor is provided to the temperature regulating part under the hopper. A controller for controlling an injection molding machine cools the circulating cooling medium by the fan and feedback controls the temperature of the temperature regulating part under the hopper when a temperature detected by the temperature sensor is higher than a preset temperature.
