Prominent operation and retrogressing operation.It addition, terminating the period starting to prominent operation from injection operation at a high speed, perform cold
But operation.
As shown in Figure 10 (b), die casting machine performs in the state of operating the most automatically, if arrive the beginning of low speed injection
Carve, then injection starts with the direction of rotation of regulation with electronic servomotor 10, controls its rotary speed and reaches predetermined
The rotary speed of low speed injection.If then arriving the start time of injection at a high speed, then penetrate with electronic servomotor 10 quilt
Speed-raising, controls its rotary speed and reaches the rotary speed of predetermined high speed injection.Penetrate with electronic servomotor 10
Rotation transmit to thread spindle 5, when penetrating with low speed via driving side drive 10a, Timing Belt 45 and the first drive 43
Rotary speed and at a high speed injection time rotary speed rotate and drive thread spindle 5.Thread spindle 5 is driven, then with screw thread if rotating
The nut body 7 that axle 5 screws togather is advanced by driving, as shown in Figure 10 (c), via relief means 31 and union body 8 and nut

In the case of speed, one-way clutch 12 dallies, and the supercharging revolving force of electronic servomotor 11 is not transmitted to thread spindle 5.
Thus, by driving control injection to reach so with electronic servomotor 11 with electronic servomotor 10 and supercharging
Rotating condition, perform the low speed injection operation in injection operation and at a high speed injection operation.
The rotation of the thread spindle 5 being rotated driving by injection with electronic servomotor 10 is reduced further after this state
Rotary speed, makes the rotary speed of the thread spindle 5 being rotated driving by the electronic servomotor 10 of injection be less than by supercharging with electronic
Servomotor 11 rotates the rotary speed of the thread spindle 5 driven, and in this stage, one-way clutch 12 is by the company of automatically switching to
Connecing state, the supercharging revolving force of electronic servomotor 11 is transferred to thread spindle 5.This revolving force is turned by nut body 7
It is changed to straight power, is transferred to penetrate piston 9 via relief means 31 and union body 8.As shown in Figure 10 (c), utilize
This supercharging power supply of electronic servomotor 11, gives required boost pressure to the motlten metal in mold,
Perform the supercharging operation after injection operation.Thus, the molding such as blowhole can be prevented bad.As shown in Figure 10 (a)～(c), supercharging
In operation, elastomer 36 keeps compressive state.
It addition, in described embodiment, before injection controls to start with the deceleration of electronic servomotor 10, start
Start the electronic servomotor 11 of supercharging, but the purport of the present invention is not limited only to this, also can start injection electrical servo
While the deceleration of motor 10 controls or start afterwards to start the electronic servomotor 11 of supercharging.
It addition, in above-mentioned embodiment, the supercharging driving force of electronic servomotor 11 obtain in supercharging operation
The thrust of piston 9, but as shown in Figure 10 (e), also can be by penetrating the driving force with electronic servomotor 10 and supercharging electricity consumption
The summation of the driving force of dynamic servomotor 11 obtains the thrust of the piston 9 in supercharging operation.
As described above, in supercharging operation, owing to elastomer 36 is compressed, therefore as shown in Figure 10 (d), supercharging operation
In, the advance amount that the advance amount (progressive position) that injection piston 9 starts from initial position starts from initial position than nut body 7
The decrement of (progressive position) few elastomer 36.Supercharging operation penetrates progressive position and the progressive position of nut body 7 of piston 9

11 carry out feedback control, as shown in Figure 10 (c), make injection piston 9 advance to the prominent stop position of regulation, stop at this position
On.Thus, the restoring force of the elastomer 36 compressed when utilizing supercharging operation, by injection piston 9 after die sinking operation starts
Biscuit is applied the pressure in extrusion direction, biscuit extrusion operation can be made to follow mold-break operations.Thus, can extrude from fixing mould
Product.
Prominent operation terminates, and proceeds to retreat operation, then drives the electronic servomotor 10 of injection to opposite direction and increase
Press with electronic servomotor 11.As shown in Figure 10 (b), at this moment, controller 13 control injection with electronic servomotor 10 with
And the supercharging driving of electronic servomotor 11, make to be driven the rotation speed of thread spindle 5 by the electronic servomotor 11 of supercharging
Degree is higher than the rotary speed being driven thread spindle 5 by injection with electronic servomotor 10.It addition, retreat the ending segment of operation, first
First stop the driving of the electronic servomotor 10 of injection, stop the electronic servomotor of supercharging afterwards, make injection piston stop
Only on the initial position of regulation.Thus, retreat in operation, can prevent one-way clutch 12 from switching to connection status, therefore can
Nut body 7 and injection piston 9 is reliably made to stop on the initial position of regulation.Thus, the one-tenth specified can stably be carried out
Type cyclic process.
It addition, the method is characterized in that, in prominent operation and retrogressing operation, control injection and use electronic servomotor
10 and the supercharging driving of electronic servomotor 11, make one-way clutch 12 not switch to connection status, for other
Structure is then not limited to described embodiment, can suitably be designed change.
Such as, in described embodiment, use and possess the device of the elastomers such as coil spring 36 as relief means
31, but also can use the device possessing oleo-gear, air bump, gas spring.
