ABSTRACT:
In apparatus for measuring injection speed of a die cast machine, there are provided a pulse generator responsive to a movement of an injection plunger for producing a pulse signal, a detector for detecting a width of the pulse signal to produce pulse width data, a memory device successively storing the pulse width data between commencement and termination of injection, and an arithmetic operation circuit for calculating an average speed in a predetermined high speed section of a stroke of the injection plunger based on pulse width data stored in the memory device.
