Abstract

PURPOSE:To provide products of steady quality and functions by measuring exhaust with a flow meter via a gas hole made in a molding die, finding quickly abnormal conditions at the time of forming and feeding them back. CONSTITUTION:An injection molding die 10 consists of cores 20a and 20b, a sprue bush 30 and a bush lock pin 40. When molding, a bush 1 is loaded in a cavity 70 as an inserted object. Each end of gas holes 80 is connected with an exhaust passage 90 and further connected with a gas flow meter 110 via a guide pipe 100.
