Accompanying drawing explanation
Fig. 1 is the structural representation of die casting machine of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, described die casting machine comprises:
Clamping System 100, it comprises, the inwall of plate 1, middle plate 4, tailgate 8, described plate 1 is provided with fixed mold 2, the inwall of described middle plate 4 is provided with the moving mold 3 corresponding with described fixed mold 2, be provided with sprue bush 11 corresponding with described fixed mold 2 and moving mold 3, between described middle plate 4 and tailgate 8, be provided with and bend elbow force-expanding machine structure 7, on described middle plate 4, thimble oil circuit board 5 is housed, the sidewall of described middle plate 4 is connected with thimble oil cylinder 6, and the sidewall that locked mode oil circuit board 9, described tailgate 8 are housed on described tailgate 8 is connected with Mode-locking oil cylinder 10;
Preferably, in described hydraulic system 300, also comprise fast energy storage device 18, described fast energy storage device 18 is connected with described injection oil circuit board 19.
Preferably, described injection system 200 also comprises different valve 14, and described different valve 14 is located in the fluid pressure line of injection system 200, for controlling oily flow.
Preferably, described injection system 200 also comprises fast row's accumulator 24, and described quick row can be provided with servo valve 240 by device.Servo valve 240 provides one dynamic to control in real time to whole injection system 200, machine setting more fast, more accurate; The metal flow of whole injection process is more steady; Can produce according to predefined die-casting technological parameter; Realize more efficient, higher-quality production.
Preferably, the injection direction of described injection system 200 is parallel with the die joint of fixed mold 2 with described moving mold 3, this structure is very beneficial for the discharge of pressure chamber and mold cavity air, easily makes die cavity form high vacuum, is beneficial to the foundry goods of producing high densification, high strength, high-air-tightness.
Described die casting machine is divided into Clamping System 100, injection system 200 and hydraulic system 300 three parts.
Injection system work subsequently, oscillating oil cylinder 15 is pushed outwardly to injection oil cylinder by injection oil cylinder 16 together with barrel 17 and tilts to Squeezing die casting machine left-external side, by the soup ladle in soup feeding machine, to barrel 11, inject molten metal, oscillating oil cylinder 15 is ajusted, then translation oil cylinder 13 pistons pull whole injection mechanism, make the mouth of barrel 17 arrive sprue bush 11 belows.Now hoist cylinder 12 rises, and the mouth of barrel 17 enters sprue bush, trace regulate oscillating oil cylinder 15 and translation oil cylinder 13 pistons make barrel mouth and sprue bush closely sealed.After this injection oil cylinder 16 is started working.Injection process is divided into three phases, and the first stage, pumping plant oil circuit board 20 fuel feeding, enter injection oil cylinder 16 back cavities through injection oil circuit board 19, and the piston stroking upward in injection oil cylinder 16 promotes drift and rises, and drift promotes again the molten metal rising in barrel 17.Now flow is little, and speed is slow.Second stage, fast energy storage device 18 is opened, pressure oil enters the back cavity of injection oil cylinder 16 fast, different valve 14 is opened simultaneously, and the oil of injection oil cylinder 16 ante-chambers enters back cavity fast, and back cavity is rodless cavity, utilize the pressure differential of back cavity and ante-chamber, form differentially, the piston in injection oil cylinder 16 moves ahead fast, and drift promotes molten metal and enters fast mold cavities shaped.Phase III, injection approaches terminal, and the piston of shot sleeve 16 moves ahead and is obstructed, and speed is slack-off, close rapidly different valve 14, pressure oil in fast energy storage device 18 flows slack-off suddenly, produces by " water hammer ", and hydraulic oil impacts the drift in barrel in the mode of high-pressure pulsating stepping, make drift to force mode stepping, the molten metal brute force leaving in sprue bush 11 enters foundry goods, makes casting forming densification, and the shrinkage cavity shrinkage porosity of foundry goods inside obtains molten metal and supplements in time and disappear.
Finally, Clamping System work, moving mold 2 is opened with fixed mold 3,6 oil-feeds of thimble oil cylinder, roof fall shaped casting from die cavity, completes a working cycles.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
