PCT No. PCT/JP85/00600 Sec. 371 Date Jun. 30, 1986 Sec. 102(e) Date Jun. 30, 1986 PCT Filed Oct. 29, 1985 PCT Pub. No. WO86/02592 PCT Pub. Date May 9, 1986.A monitor device for a screw position and an internal die pressure is used by an injection molding machine for driving a screw (29) by a servo motor (27). During injection, a sequentially updated address from an address generator (20) is supplied to first and second memories (16, 18) through an address switching circuit (21) to designate addresses of the memories (16, 18) so that the output from a pulse counter (15), which represents the screw position, and the output from an analog/digital converter (17), which represents the internal pressure of a die (30), are sequentially stored in the first and second memories (16, 18). During monitoring, the values stored in the first and second memories (16, 18) are read out through the address switching circuit (21) which has performed switching, and the relationship between the screw position and the internal die pressure is displayed on a display unit (25).
