A method for monitoring abnormality of a mold-clamping mechanism of a molding machine and a molding machine for estimating abrasion amount without disassembling a mold-clamping mechanism in the molding machine for inspection, and making it possible to be operated until the time just before a quality deficiency of a product occurs, perform maintenance with minimum disassembly for inspection, and improve productivity. A die casting machine 10 using a toggle mechanism 30 for a mold- clamping mechanism 16, and a strain gauge 40 is stuck to the toggle mechanism 30. The strain gauge 40 is connected to stress judging means 47 via the signal amplifier 42. An abrasion amount is calculated from data stored in the stress judging means 47, and if a timing of maintenance of a mold-clamping mechanism is judged from correlation of the abrasion amount and quality of a molded product, maintenance can be performed with minimum disassembly for inspection, thus making it possible to improve productivity.
