置。[Scope of Claim for Utility Model Registration] 1. A melting/heating tank, a reciprocating pump installed inside the melting/heating tank, and a communication between the reciprocating pump and a dissolving tank outside the melting/heating tank to the reciprocating pump side. A supply path equipped with a check valve that only allows the flow of molten material is connected to a reciprocating pump and an injection nozzle to the mold outside the melting/heating tank, allowing only the flow of molten material to the mold side. a discharge path provided with a check valve that allows the reciprocating pump to reciprocate; a molten material recovery path that recirculates the reverse melting material discharged from the reciprocating pump to the supply side of the molten material to the reciprocating pump; 1. A hot chamber die-casting device comprising: a valve device for switching the discharge of molten material to a discharge path or a recovery path; and an air bleed valve provided on the upper end wall of a reciprocating pump and opened from the outside. 2. The supply route passes through the internal space of the melting and heating tank,
2. The hot chamber die-casting apparatus according to claim 1, wherein the recovery path circulates the molten material discharged from the reciprocating pump into the internal space of the melting and heat-insulating tank. 3. The hot chamber die-casting apparatus according to claim 1, wherein the recovery path circulates the molten material discharged from the reciprocating pump to the melting tank. 4. The collection path has an injection nozzle at its terminal,
4. The hot chamber die-casting apparatus according to claim 1, wherein the flow path resistance is set to be the same as that of a discharge path to an injection nozzle that injects the molten material into the mold. 5. The hot chamber die-casting apparatus according to claim 1, 2, 3 or 4, wherein the reciprocating pump is a bellows type pump that is axially expandable and retractable.
