The prior art & die casting machine performs casting by injecting a cavity of a plunger holder. Effect of large speed and injection pressure The hydraulic cylinder of the plunger in the sash controls the filling condition and appropriately controls the injection. For example, the melt starts to be emitted without causing the melt in the injection sleeve to be low. Next, the tip of the melt is switched to a high speed before solidification is performed to cool the melt. Then, the injection pressure is rapidly increased and the liquid is solidified. The metal smelting liquid such as Sau is shot from the molten metal by the quality of the cast product. Therefore, the driving melts the melt to correspond to the exit velocity and the injection pressure of the molten fluid between the casting cycles. In the initial injection stage of the cavity, when the injection speed is changed to the inlet of the cavity in the mold for the air to be entangled, the melt is filled in the cavity, and the molten liquid is filled into the cavity to fill the cavity. Melting and melting The first drawing shows an injection device of a conventional die casting machine. In the die casting machine 100 shown in Fig. 1, the mold 110 has a cavity 111 in which the melt is filled, and the mold hole 111 is connected to the cavity 111 to connect the injection sleeve π 2 to be inserted into the injection sleeve 丨 2 The injection plunger 丨 3 is injected into the cavity 1 1 1 by the molten solution supplied from the liquid supply port 4 4 with the long shank 5 toward the mold U 0 . The plunger 11 3 is driven via a rod 1 25 connected to the piston 1 22. The hydraulic cylinder 120 has an injection cylinder chamber 119 and a pressurization cylinder chamber 123 that are integrally formed. In the injection cylinder chamber 121, there is built therein

The ascending characteristic makes the casting close to the boundary! . In other words, when the pressure at the time of supercharging is controlled, the occurrence of the burr is reduced, and the curve of the rise and the rise time is obtained, whereby the die-cast product in which the flow rate of the hydraulic oil is performed is also performed. That is, the supercharging control, however, is the same as the above, and the counter valve 135 at the time of supercharging is required to be immediately controlled to stop the supercharging. If such a valve is provided, it is possible to adjust the valve opening of the servo valve or the like immediately. θ causes the price of the hydraulic device 130 to be different from the other. If the pressure at the time of supercharging is not controlled, the flow regulating valve cannot produce a burr on the precise split surface, j $ condition, mold accuracy, etc. , from the mold one. ...The reason for the decrease in the quality of the cast product is to use the feedback control to implement the shot: J:J, the machine's shot-out* can be reduced in real time, and the force control can be manufactured, and the generation of the princess can realize the other of the present invention.

After switching to the high speed VH than the low pressure 1 output speed V, the melt starts to the cavity 6: the moving speed of the plunger 63 decreases, and the injection speed 丫 decreases rapidly = Ϊ Ϊ t The speed Vd indicates that the control device 4 detects the deceleration start point of the deceleration start from the position information of the plunger 63 detected by the position detector 49 based on the position data previously stored in the memory 42 indicating the deceleration start point L. The ejection speed V of the dazzling liquid filled in the cavity 61 is lowered and the plunger 63 is several When the forward pressure is not possible, the injection pressure P rises and is expressed as the third pressure pd. Further, the slope of the third speed Vd indicating the deceleration of the plunger 63 is adjusted by adjusting the valve of the servo valve 28 by the control device 40. The degree of injection is adjusted to 2197-5775-PF(M).ptd, page 20, 1274611, and the invention (16) is adjusted to the dynamic pressure control of the hydraulic oil filling portion 21 of the hydraulic cylinder 2.

Description of Invention (18) A second embodiment of the pressure of the present invention will be described with reference to Figs. 4 and 3. Fig. 3 is a view showing an example of the injection/emission velocity waveform referred to in the first embodiment. Fig. 4 is a structural diagram of the injection device of the second embodiment of the present invention. Further, in Fig. 4, the same structure as that of the injection device of the die casting machine of the application form of the second embodiment is used. In the same J apparatus, the injection μ of the first embodiment described with reference to Fig. 2 is used to drive the injection piston $1, and the slanting plug 6 is driven by a so-called inlet throttle. Therefore, the control servo valve 28 of the first embodiment is necessary for control in which the flow rate is relatively large. When the value of "beta" is limited, the capacity of '28 is limited." It is also difficult to properly perform the high-speed shot of the word "speaking" in Fig. 3. The second starting point D = shown in Fig. 4 is an injection device that overcomes the above-mentioned problems, and the servo M is applied in the servo mode, and the servo valve 28 having a small capacity can be used for high-speed injection. Capacity change The difference between the die casting machine injection device shown in Fig. 4 and Fig. 2 is as follows. In the injection molding machine shown in Fig. 4, the first flow path 27 and the second flow path 26 shown in Fig. 4 are added between the third flow path 27 and the second flow path 26, and the road (second action liquid increasing device) 70 is added. Further, a front outer loop circuit (first action liquid increasing device) 8 that recirculates the operating oil to the space s of the hydraulic cylinder 2 is added from the first hydraulic booster port. For example, when it reaches a stage where the operating oil for the low-speed injection control of the servo valve 28 can be miniaturized, it is the second action liquid increasing device of the present invention.
