PURPOSE:To indicate relation between a screw position and a pressure in a mold at an indicator when the condition of the machine is to be monitored by a method wherein the screw position and the internal pressure of the mold upon injection is memorized into a memory moment by moment. CONSTITUTION:When the injection molding machine is effecting injection, an address generator 20 outputs addresses sequentially from address 0 and assigns the address sequentially through an address switching circuit 21. The value of pulse counter 15 at that moment in that address or the position of the screw, is memorized in the memory 16 while the value of an A/D converter 17 at that moment or the value of internal pressure of the mold is memorized in the memory 18 respectively. When a monitor command is inputted from a manual operating input device 24, a CPU11 switches the address switching circuit 21 to CPU side and accessions the memory. Therefore, the position of the screw is read out of the memory 16 and the internal pressure of the mold, memorized in respective addresses, is read out of the memory 18 while the relation between the screw position and the internal pressure of the mold may be indicated in a graph on the picture of a CRT indicating device 25 through a CRT control circuit 12.
