The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, shown in Fig. 2, the present invention includes solid plate 1, moving platen 4, four pull bars 3 and die cylinder 5, four pull bars 3 are successively through after moving platen 4 and solid plate 1 locating hole separately, one end of four pull bars 3 and solid plate 1 are affixed, solid plate 1 is vertically fixed on injection machine support, the other end of four pull bars 3 and moving platen 4 form and are slidably matched, four pull bars 3 are fixed on injection machine support, the solid plate center that is positioned at four pull bars has solid plate groove 8, a matched moulds half mold 6 is housed in solid plate groove 8, the moving platen center that is positioned at four pull bars has moving platen groove 9, another matched moulds half mold 7 is housed in moving platen groove 9, two matched moulds half molds 6, 7 are positioned on same axis, moving platen 4 outer side center are connected with the connecting rod of die cylinder 5, the present invention also comprises that 2, four pole plate 2 of pole plate that eight block structures are identical are arranged on respectively the interior junction of pull bar and solid plate 1 separately, and other four pole plate 2 are arranged on respectively the interior junction of pull bar and moving platen 4 separately.
As shown in Figure 1 and Figure 2, a side of the pole plate 2 that described eight block structures are identical has groove, and 16 iron cores 10 that are wound with respectively coil windings 11 are vertically distributed on by row, column on the pole plate groove of wearing outside pull bar centre bore, and iron core 10 flushes with pole plate 2.
Sensor connection control system are housed for controlling the speed of flow and then the control cylinder rod of die cylinder 5 on the support position that is about to close at two matched moulds half molds.Control system and support are originally not shown in FIG..Die cylinder is controlled Flow-rate adjustment speed by control system, and it is provided with sensor for FEEDBACK CONTROL closure pressing speed on two moulds are about to close the support of locating, and reduces inertia impact.
The present invention supports the use pole plate 2 and two matched moulds half molds, and while guaranteeing that two matched moulds half molds close, the spacing of four pole plate and other four pole plate is zero, for guaranteeing to provide best magnetic assisted lock mould.
The mould assembling action that die cylinder 5 of the present invention is realized, first, realize fast reasonable shifting formwork, i.e. rapid mould-moving when two matched moulds half molds close far away, before being about to close, matched moulds half mold reduces moving platen translational speed by controlling the flow of die cylinder 5, inertia impact while guaranteeing matched moulds is little, realizes steady matched moulds.Then, cylinder rod provides thrust and realize locked mode under magnetic force is auxiliary.Wherein cylinder rod thrust size deducts assisting magnetic size for required clamp force.Die cylinder of the present invention is realized the function of shifting formwork and locked mode, during shifting formwork, realizes speed regulate by control system feedback flow control valve.During locked mode, auxiliary lower of magnetic force, need provide less hydraulic coupling, reduce emptying risk far away.
Operation principle of the present invention is:
During work, first according to the selected eight supporting pole plate of mold thickness, be installed on respectively the place, four angles of solid plate 1 and moving platen 4.According to required rapid mould-moving speed, by control system, control the flow of die cylinder 5, when shifting formwork to matched moulds half mold 6 and another matched moulds half mold 7 are about to close, by sensor feedback, control in time flow to reduce speed.Complete the shifting formwork action of die cylinder 5.When mould closes, the iron core energising in pole plate 2, makes the pole plate of the cover half utmost point one side and the pole plate of the dynamic model utmost point one side produce phase different pole, be respectively the N utmost point and the S utmost point, the generation magnetic force that attracts each other, provides clamp force, the locked mode action of auxiliary now die cylinder 5.Because pole plate is arranged on respectively solid plate and moving platen four jiaos, the magnetic force size attracting each other is identical, magnetic force equalization stable.The burden that can alleviate die cylinder by magnetic assisted lock mould, to guarantee oil cylinder optimum working efficiency, prevents oil cylinder emptying.
