FIELD: foundry, in particular, casting equipment. SUBSTANCE: mold half have ejectors and counterpushers mounted on common plate. Counterpushers are provided with through beveled slots. Pins mounted in this mold half are provided with beveled portions engageable with counterpusher bevels. Pins are connected with hydraulic cylinders. Upon crystallization of castings, hydraulic cylinders actuate pins to move them till pin beveled portions cooperate with counterpusher bevels. When counterpushers come into contact with separation surface, they carry away plate with ejectors while following the path of separation of halves. Casting is ejected by ejectors and left in other mold half. Ejection apparatus may be used for pressure die, box and investment casting, for producing cores, as well as for casting in permanent metal molds. EFFECT: wider operational capabilities, increased efficiency and reliable retaining of castings in predetermined mold half. 1 dwg |
