Abstract

PURPOSE:To make it possible to detect the misblowing of a resin and to stop each mold, by means of a compressed air path, whose one end opens to a blow mold and the other end connects to a flow control valve and an air pressure transducer via an outer pipe, at the bottom mold of an injection blow molding machine. CONSTITUTION:The sleeve 11 is inserted into the bottom mold 10 of the movable platen 9, to which the blow mold 3 is attached, to open the annular compressed air hole 12 which connects to the outer pipe 14 via the path 13. The pipe 14 is equipped with the flow control valve 15 and the air pressure transducer 16. When the closed- end parison is burst or damaged by the air blowing pressure, the air leaks into the mold 3 and flows into the valve 15 via the hole 12, and the transducer 16 is operated to detect the misblowing and to stop the mold 3.
