Abstract

PURPOSE:To reduce time of a vacuum formation and consumption of energy and improve an operation efficiency, by sucking and evacuating the air in a cavity space from upper and lower mold frames through a sprue runner in a operation which makes the vacuum in a mold apparatus. CONSTITUTION:When an upper mold platen 5 is lowered integrally with an upper mold 1, a vacuum cover 12, a pressure-resistant cylinder 4, the upper mold 1 is pushed down, being matched with a lower mold 2, and a parting face of upper and lower molds 1, 2 is sealed by sealing member 11. A vacuum pump being operated, air in a cavity space 3 is sucked, evacuated via a sprue runner 3a, an inner space 12' of the vacuum cover 12, an exhaust hole 12f, an exhaust pipe 12g, a vacuum is formed in the cavity space 3. At an injection stage the pressure-resistant cylinder 4 and its nozzle part 4b are lowered, a nozzle 4a is contacted to a sprue bush 3b and a molten resin in the pressure-resistant cylinder 4 is injected from the nozzle 4a. The molten resin is sucked and flows into every corners in the cavity space 3.
