Abstract
A quality management device and a die-cast molding machine capable of suitably inspecting quality in relation to the amount of blowholes of a die-cast product which is cast according to a PF die casting method are provided. A quality management deviceperforms the quality management of the die-cast product formed according to the pore free die casting method of supplying oxygen to a cavity Ca and an injection sleevecommunicated with the cavity Ca and, in that state, ejecting a melt in the injection sleeveinto the cavity Ca. Further, the quality management devicehas a vacuum sensorwhich detects the air pressure in the cavity Ca and a control devicewhich makes good/defective judgment of quality of the die-cast product in relation to the amount of blowholes based on the air pressure detected by the vacuum sensorduring injection.
