The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of two-plate type mould clamping mechanism, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also Fig. 2, shown in Figure 3, Fig. 2 is according to two-plate type mould clamping mechanism schematic diagram of the present utility model, and Fig. 3 is the side view of Fig. 2.Two-plate type mould clamping mechanism of the present utility model, it mainly comprises: moving platen (11), solid plate (9), gripper shoe (20), Mode-locking oil cylinder, controlling organization, solid plate (9) and gripper shoe (20) support four pull bars (10), constitute frame structure, moving platen (11) and pull bar (10) are slidingly matched, wherein: described matched moulds plate is two, comprises moving platen (11) and solid plate (9); The piston rod (21) of direct express oil cylinder (13) is installed on the moving platen (11); Also be provided with a cover mode transfer device on described two-plate type mould clamping mechanism, the baffle plate (14) on the moving platen (11) can be fitted with the end face of clasp nut (12) on the mode transfer device; The cylinder barrel of Mode-locking oil cylinder is fixed on the solid plate (9), and its piston is connected with moving platen (11) by pull bar (10), clasp nut (12).
See also Fig. 3, Fig. 4, shown in Figure 5 again; pull bar (10) cooperates with clasp nut (12); baffle plate (14) is provided with lucky system (17); two folding oil cylinders (15) promote two clasp nuts (12) respectively; described two clasp nuts (12) connect two other clasp nut (12) by two push rods (16) respectively; on described baffle plate (14), also be provided with the system of closely connecing (18); lucky making sheet (19) is installed on clasp nut (12), and the said structure acting in conjunction can make the mode transfer of clamping more convenient.
See also Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, shown in Figure 11, pull bar (10) is provided with detent mechanism, the detent mechanism of clasp nut (12) obvolvent pull bar (10).Therefore when both obvolvents, the power that Mode-locking oil cylinder mesohigh oil acts on the pull bar can pass to moving platen by clasp nut, and then required clamp force is provided.Four pairs of grooves that pull bar (10) and the cross section at clasp nut (12) place of matching are designed to along the circumferential direction all arrange and projection can make both cooperations tightr.
Be used as piston rod that part of thick of Mode-locking oil cylinder in the pull bar (10) than remainder.
Under the certain condition of oil cylinder operating pressure, the size of clamp force depends primarily on the diameter of oil cylinder, but cylinder diameter cross conference and bring restriction such as bulk, leak, make a series of problems such as maintenance, therefore adopt four Mode-locking oil cylinders that required clamp force is provided here.
Below the simple locked mode process of describing.See also Fig. 2, Fig. 3, Fig. 4, shown in Figure 5 again, with the detent mechanism of clasp nut 12 obvolvent pull bars 10.When locked mode, be fixed on the solid plate 9 by cylinder barrel, the piston rod 21 that is installed in the direct express oil cylinder 13 on the moving platen 11 promotes moving platen 11 and moves around, when paste when neat the left side of 14 inner faces of the baffle plate on the moving platen 11 and clasp nut 12,17 whiles of Ji system on the baffle plate 14 contact and send signal with the inclined-plane on the pull bar 10 and give controlling organization (as PLC controller of the prior art, do not draw among the figure), illustrate that moving platen 11 has been incorporated into the position, controlling organization promptly sends next instruction, start folding oil cylinder 15, allow two folding oil cylinders 15 promote 12 rotations of two clasp nuts respectively, these two clasp nuts 12 drive two other clasp nut 12 rotations by two push rods 16 respectively, when closely the connecing system 18 on being installed in baffle plate 14 is sensed the lucky making sheet 19 that is contained on the clasp nut 12, stop 15 actions of folding oil cylinder this moment, clasp nut is rotated in place.The left chamber cut-in pressure oil of four the oil cylinder groups (high pressure cylinder) on the solid plate 9 produces a power and through clasp nut 12 power is delivered to moving platen 11 by pull bar 10 (being the high pressure cylinder piston rod), and then mould is closed tightly subsequently.Analyze from the transitive relation of power, the positioning form of this obvolvent pull bar is compared with general direct press type, can make the contraction in length of pull bar force part, thereby has improved the rigidity of clamping system.This mechanism bears the template of clamp force effect and has only 11 two of solid plate 9 and moving platens, 20 supporting positioning actions that play pull bar of back support plate, and do not bear clamp force.Therefore have relatively simple for structure, the characteristics of good rigidly.
During die sinking, opposite with above-mentioned steps, i.e. the right ventricle's cut-in pressure oil by four oil cylinder groups on the solid plate 9 at first, this moment, mould was opened slightly, pull bar 10 is to left movement, and the power between itself and the clasp nut 12 weakens gradually, finishes die sinking by folding oil cylinder 15, direct express oil cylinder 13 then.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
