Abstract
PURPOSE: To operate and display a maximum injection speed accurately by forming stripe patterns on the piston rod etc. of an injection plunger tip, generating pulse signals by irradiating a light beam thereto and electrically processing these.
CONSTITUTION: Stripe patterns 24 are formed at a predetermined pitch P on the outside surface of a piston rod 23 connected to an injection plunger tip 18 force- feeding the molten metal in a sleeve 15 into a cavity 14 or a shaft moving synchronously with the rod 23. A light beam is irradiated to these stripe patterns 24 and the quantity of the reflected light thereof is detected with a detector 25. The pulse signals are sent to an injection speed measuring and displaying circuit which in turn divides the predetermined pitch value by the minimum value of the period of the pulse signals to operate a maximum injection speed and digitally displays the same. This method enables the maximum injection speed to be set accurately according to casting conditions and improve the yield and quality of cast products.
