Molding machine, clamping system, burr detection method, and abnormality detection method

摘要

A molding machine able to detect a burr or other abnormality by detecting the position of tie bars. A control device detects an occurrence of burrs according to whether or not displacement amounts of pistons associated with the tie bars, using position sensors which detect the position of the pistons. The position sensors detect position from the start of injection to the completion of the injection to determine whether detected values are within a permissible range.
