The specific embodiment
Novel die casting machine; On the basis of common die casting machine; At first remove the original travel switch on the injection position, the shot piston 11 of die casting machine is connected with grating chi mechanism with rotary encoder through connecting plate 5, and the pull bar front end of grating chi 2 and connecting plate 5 usefulness are equipped with jack panel 6 and are fastened together; Pull bar front end at grating chi 2 is fixed with positive stop 4 and limitation travel switch 3, play the injection backhaul spacing with injection work the initial point effect of posting a letter of opening.The base 8 of limitation travel switch 3 is fixed on the injection frame 10 of die casting machine, and the bearing 7 of rotary encoder 1 is fixed on the injection frame 10 of die casting machine, and rotary encoder 1 is connected with the Programmable Logic Controller of die casting machine.The model of rotary encoder 1 is: the XZ-550A type, the model of grating chi 2 is: XZC-550A type, Programmable Logic Controller (PLC) model are the S7-300C type that Siemens Company produces.
Extruding die casting I is installed between quiet template 24 of die casting machine and movable plate 25, and extruding die casting I mainly is made up of cover half, dynamic model two parts, and cover half comprises cover half core 14, solid plate 12; Cover half core 14 is connected with solid plate 12, and taper pin 17, wedge block 18 are installed on solid plate 12, and dynamic model comprises moving-mould-core 15, moving platen 13; Moving-mould-core 15 is connected with moving platen 13; Moving-mould-core 15 is provided with side slide 19, extrusion die 16, and moving platen 13 is connected with support 21, and support 21 is positioned at the outside of side slide 19; Extrusion oil cylinder 22 and extrusion piston 20 are installed on support 21, extruding reversal valve 9 is installed on die casting machine movable plate 25.
The extrusion die 16 of extruding die casting, extrusion piston 20, extrusion oil cylinder 22 are as the local feeding mechanism of pushing; Extrusion piston 20 reaches through extrusion oil cylinder on the extruding reversal valve 9 control extruding die castings; When carrying out the injection supercharging, accomplish being in the local extrusion modling of semisolid die casting in the die cavity.
The operation principle of the invention:
When injection started beginning, positive stop 4 was thrown off limitation travel switch 3, and slow shot begins, and is connected the rotary encoder 1 continuous detecting injection position on the shot piston, and (PLC) controls injection speed piecemeal through Programmable Logic Controller.
The secondary fast shot is when arriving desired location in the injection position, to start the two-speed driver's valve 30 on the former die casting machine, and two-speed accumulator 26 fuel feeding carry out the fast shot action.Three grades of superchargings also are when arriving according to the desired location that rotary encoder 1 records continuously, start the supercharging driver's valve 27 on the former die casting machine, supercharging accumulator 28 fuel feeding, and supercharging starts.
Meanwhile, by the external supercharging reversal valve of Programmable Logic Controller (PLC) control, the hydraulic pressure extrusion oil cylinder that starts on the extruding die casting carries out the part extruding to foundry goods synchronously.
The operation principle of extruding die casting: when die casting machine extruding die casting was in the matched moulds state, the taper pin 17 on the cover half slided to position shown in Figure 4 with the side slide on the dynamic model 19, and breaks away 19 by wedge block 18 wedgings.At this moment between moving-mould-core 3 and side slide 19 ends, between taper pin 17 and the side slide 19, all leave 4-6 millimeters spacing between wedge block 18 and the side slide 19.When Programmable Logic Controller (PLC) will push the compression signal notice extruding reversal valve 9 of die casting; Extrusion oil cylinder 22 commutates in the injection supercharging; Extrusion piston 20 reaches, extrusion die 16 carries out local extrusion modling to having formed semi-solid foundry goods 23 in the mold cavity in real time.Machine pressurize time-delay ends, extrusion oil cylinder 22 switching-overs, and machine die sinking after extrusion piston 20 backhauls, the side slide 19 on the dynamic model is thrown off wedge block 18, and taper pin 17 slips off side slide 19, draws back extrusion die 16, and die sinking ends, and the liftout tank 29 of die casting machine ejects foundry goods 23.To ending, whole local extrusion process is accomplished.
