Method and inspection device used for the cyclic production of injection molded parts

Method for monitoring output in the cyclic and process-controlled production of injection-molded parts (10) in multi-cavity casting molds with row-by-row disposition of the injection-molded parts by monitoring the handling of the injection-molded parts (10) in cooling cavities of the post-cooler following removal from the injection molds by means of sensors (28, 40, 50, 60) particularly photoelectric barriers (60, 60′, 60″), characterized in that an inspection is carried out following the filling and an inspection is carried out following the emptying of the cooling cavities of the post-cooler where the inspection takes place row by row by means of fixedly disposed sensors located in proximity to the post-cooler, and the cooling cavities are obligatorily moved to and past the sensors in order to recognize errors, either the absence of an injection-molded part (10) or the retention of individual injection-molded parts (10) and immediate initiation of a safety intervention.

Monitoring device (40, 50) for the cyclic and process-controlled production of injection-molded parts (10) in multi-cavity casting molds with row-by-row disposition of the injection-molded parts by monitoring the handling of the injection-molded parts (10) following removal from the injection molds (8, 9) and the cooling cavities in the post-cooler by means of sensors (28), particularly by means of photoelectric barriers (60), characterized in that at least one sensor (28) is fixed relative to the rows of injection-molded parts, where the sensors (28) are disposed so that all cooling cavities obligatorily pass by for a check of each position in the row, where the sensor monitoring takes place in proximity to the injection molds (10) and/or to a post-cooler for immediate recognition of errors and initiation of a safety intervention.
