PROBLEM TO BE SOLVED: To provide a resin pressurization casting device capable of adjusting pressure in a resin tank to become a target casing speed database selected by CAE or the like by obtaining loss including pipe resistance and resin viscosity change by measuring a pressure difference and a flow rate while passing the pipe from the resin tank for storing resin and a mold.SOLUTION: A resin pressurization casting device includes: a resin tank 1; a pipe 4 connecting the resin tank 1 and a mold 8; a flow rate measuring sensor 5 for measuring a resin amount; a resin pressurization sensor 6 for measuring a resin pressure; a target casting speed database 9; and a casting speed control part 10 that stores a measurement value of the flow rate measuring sensor 5, a measurement value of the resin pressurization sensor 6, and pressurization force data of the resin tank 1, obtains a loss coefficient caused by pipe resistance of the pipe 4, controls the pressurization force of the next step to the resin tank 1 and controls the speed of casting of the resin into the mold 8 based on the loss coefficient and information stored in the target casting speed database 9. |
