A pressure measuring device for an injection molding machine having a plasticizing screw operated by a rotary drive and an injection drive includes a load detector having a deformation zone which forms part of a transmission member of the injection drive and is of reduced cross section, and a sensor. The deformation zone elastically deforms in response to a driving force acting on the transmission member, with the sensor measuring a change in shape of the deformation zone.

An injection unit in which an offset load is not applied to a ball screw for moving an injection screw. A pusher plate is provided that is moved while being guided by guide rods extending between front and rear plates, and is mounted with the injection screw and the ball screw so as to be rotatable but axially immovable. The ball screw is threadedly engaged with a nut mounted to the rear plate so as to be unrotatable and axially immovable. A support plate is coupled through coupling rods to the ...

A digital-to-analog converter using capacitors and an operational amplifier, which can be highly integrated due to its small area and which can rapidly perform a stable converting operation. The digital-to-analog converter includes a data input unit, a first conversion unit, a second conversion unit, and a signal output unit. When digital data is input to the data input unit, the data input unit is connected to the first conversion unit or the second conversion unit. The first conversion unit ch...

A controller of an injection molding machine which compensates a delay in an injection velocity changeover and a delay at the time of changeover to the pressure-holding process, and is capable of more accurate and stable injection velocity control and changing control from the injection velocity control to pressure control. In the injection process, a motion command is outputted in every sampling period .tau. according to the command injection velocity. When a screw position overshoots the set v...

An injection molding machine that distinctively displays operation parameters attributed to molds, which are set by designating a mold to be used, and the other operation parameters, to thereby prevent setting errors. The machine has storage means for storing and saving the operation parameters attributed to molds, which are determined by molds, with respect to each mold, and storage means for operation parameters to be applied for operating the injection molding machine. In the storage means fo...

A drive assembly for rotating and translating a shaft comprising a hollow shaft motor and a fluid cylinder. The hollow shaft motor rotates the shaft and the fluid cylinder moves the shaft lengthwise. The drive is particularly useful in the injection unit of an injection-molding machine. In one preferred embodiment the injection unit includes a hollow electric motor and a hydraulic cylinder. A first cylinder wall of the hydraulic cylinder is joined to a rotor of the hollow motor. A second cylinde...

Disclosed is a drive unit operable to translate and rotate a shaft, the drive unit including: (i) a hollow electric motor having a rotor, (ii) a fluid cylinder, (iii) means for connecting the shaft to the rotor of the hollow electric motor, (iv) means permitting the shaft to move lengthwise coupled with the fluid cylinder, and (iv) means connecting the fluid cylinder to the shaft, whereby the shaft may be rotated by the hollow electric motor and moved lengthwise by the fluid cylinder, and wherei...
