A molding machine able to stably detect an abnormality of a squeeze pin, for example, a die cast machine having a squeeze pin able to apply pressure to a melt of a cavity repeatedly performing a molding cycle including a pressing process making the squeeze pin advance and applying pressure to the melt of the cavity in a state where the melt is filled in the cavity and a spray process making the squeeze pin advance and performing at least one of lubrication and cooling of the squeeze pin in the state where the melt is not filled in the cavity, and, in the spray process, detecting a stroke of the squeeze pin and detecting an abnormality of the squeeze pin based on a comparison of the detection result about the stroke and a predetermined reference value.
