Abstract
PURPOSE:To form by injection a product with uniform dimension and quality, eliminating defective product, by controlling metallic die cooling with a temperature sensor and at the same time controlling molding processes with a timer. CONSTITUTION:As soon as filling of a resin in a metallic dies 3 and 4 is started, a timer 8 is actuated and at the same time a temperature sensor 6 is actuated. After the timer notified that a minimum forming time has passed and temperature measured by the temperature sensor 6 has dropped to a specified temperature set by a temperature judging device 7, the metallic dies 3 and 4 are fully opened. Products with uniform dimension and quality are produced by using the timer and temperature sensor in parallel, even if the temperature in the metallic dies drops excessively due to, for instance, abnormality in the time of the forming cycle.
