Abstract
PURPOSE: To provide the titled device capable of enhancing the reliability and yield in producing a molded article having an insert by a method wherein ejector pins for detecting the mold releasing force and the deformation mode for the article, and an alarm is raised at the time when the mold releasing force reaches to a preset value.
CONSTITUTION: Load sensors 8, 11, 13 for detecting each deformation mode are connected with displaying parts 15A, 15B, 15C through amplifiers, respectively. When the measured load exceeds each of load values preset by setting dials 16A, 16B, 16C, a red lamp at one of alarm displaying parts 17A, 17B, 17C corresponding to the load value concerned is turned on. When the molded article 4 is separated from upper and lower molds 2, 1 almost simultaneously with a mold opening operation, a load of a profile 18 is applied to the load sensor 8, a load of a profile 19 is applied to the load sensor 11 by the projection of the ejector pin 3A and a load of a profile 20 is applied to the load sensor 13 by the projection of the ejector pin 5A. Each time when the three types of loads exceeds the preset values FA, FB, FC respectively, the alarm displaying is performed.
