<p>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 device 3 performs 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 sleeve 27 communicated with the cavity Ca and, in that state, ejecting a melt in the injection sleeve 27 into the cavity Ca. Further, the quality management device 3 has a vacuum sensor 51 which detects the air pressure in the cavity Ca and a control device 70 which 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 sensor 51 during injection.</p> |
