Pressurizeed with the liquid level 7a of the raw material 7 to flowing into because of pressure differential, then possess the function as compression casting device 1.
First, illustrate former approach, i.e. illustrate that the pressure of the inside for making melting chamber 20 rises relative to the pressure of die cavity 30
Method.Using force (forcing) pump 41 make rare gas to melt chamber 20 inside import and to melt chamber 20 inside pressurize
(the 1st pressurization operation of Fig. 4).The reduced pressure of die cavity 30, therefore, the pressure differential of the internal pressure and die cavity 30 that melt chamber 20 becomes
Height, the liquid level 7a for flowing into the raw material 7 of mold 2 are pressurized.Now, the pressure melted in chamber 20 is detected at least with pressure transducer 43
Power.When pressure transducer 43 detects the pressure that melts in chamber 20 becomes the pressure of regulation, control device 52 stops by pressurizeing
Pump 41 supplies rare gas and stops pressurization with the time of regulation to chamber 20 is melted (pressure of Fig. 4 keeps operation).During this period

Method.Rare gas are imported into the inside in melting chamber 20 using force (forcing) pump 41 and the internal pressurization in chamber 20 will be melted and certain is remained
The degree of kind (for example, atmospheric level).In latter method, pressure change will not be made to higher than this using force (forcing) pump 41.Here,
That is, discharge the internal gas of die cavity 30 using exhaust pump 51, the internal pressure of die cavity 30 reduce at leisure (Fig. 4 the 1st plus
Pressure operation).The internal pressure for melting chamber 20 is uprised with the pressure differential of die cavity 30, and the liquid level 7a for flowing into the raw material 7 of mold is pressurized.
Now, the pressure in die cavity 30 is detected at least with pressure transducer 53.When pressure transducer 53 detects the pressure in die cavity 30
When power becomes the pressure of regulation, control device 52 stops using exhaust pump 51 to the aerofluxuss of die cavity 30 and with the time stopping of regulation
Pressurization (pressure of Fig. 4 keeps operation).During this period, the pressure that control device 52 maintains this constant with the time by regulation
Mode controls exhaust pump 51.After it have passed through the stipulated time, control device 52 restarts the aerofluxuss of rare gas again, from the pressure
Start to reduce pressure (the 2nd pressurization operation of Fig. 4).
