METHOD FOR DETECTING INSERT OBJECTS IN AN INJECTION-MOULDED PART

摘要

The present invention is characterized in that the inserts 1, 8 are located in the cavity 3 surrounded by the mold wall 4 of the mold 5 before the start of the injection molding cycle, (1, 8) in the injection-molded part (2), which are connected to the injection-molded part (2) rigidly. According to the invention, at least one temperature sensor or pressure sensor (6, 7) is provided in the mold wall (4) to measure at least one measured Record and analyze the values. Based on the analysis, it is determined whether the inserts 1, 8 were present at certain positions in the cavity 3 during the injection molding cycle. Finally, after the injection molded parts are separated, the injection molded parts 2 are classified as acceptable or defective based on the analysis of the measured values.
