Claims

[Scope of Claim for Utility Model Registration] Upper and lower molds defining the product cavity, sleeves formed in the upper and lower molds to store molten metal, a counter plunger disposed inside the sleeve to receive the molten metal, and a counter inside the sleeve. A pressurizing plunger arranged to face each other above the perangier, a hot water inlet formed in the sleeve between the counter plunger and the pressurizing plunger, and a hot water inlet in the sleeve communicating the product cavity and the sleeve. It consists of an opening in the runner, a control port formed between the opening in the sleeve and the hot water supply port, a hot water storage means provided in the control port, and a hot water discharge device provided in the control port. When the counter plunger closes the opening with molten metal stored in the counter plunger, the stored molten metal is stored in the hot water storage means through the control port, and at least when the pressure plunger pressurizes the stored molten metal, A vertical pressure casting device characterized in that a control port is arranged so that the control port is blocked by a pressure plunger.
