Detailed description of the invention:
Below in conjunction with accompanying drawing, detailed description of the invention is elaborated: in one embodiment of the present of invention figure shown in Fig. 1 ~ Fig. 3, a kind of precise injection machine clamping mechanism, include: the structural frame be made up of solid plate 3, moving platen 5, rear pattern plate 9, guide pillar 4, guide pillar 4 is located between solid plate 3 and rear pattern plate 9, moving platen 5 is enclosed within can along guide pillar slippage on guide pillar 4, also be provided with moving platen rapid moving mechanism, Mode-locking oil cylinder mechanism; Wherein:
The rectangular in cross-section of described structural frame guide pillar 4, described moving platen 5 four bights on guide pillar cylinder, lower cylinder is provided with roller 11, guide pillar 4 medial surface is provided with roller 1; Because four bights of moving platen 5 are equipped with roller, limit moving platen 5 and move in the plane at its place, can only move in the direction perpendicular to this plane.When roller has wearing and tearing, the spacer thickness at adjustable roller seat back is to adjust the gap between roller and guide pillar.Because the friction between moving platen and guide pillar is rolling friction and gap between adjustable roller and guide pillar, therefore the depth of parallelism between moving platen and solid plate can be guaranteed completely.The present invention also takes following measure: the solid plate 3 of described structural frame is fixed on injection machine support, the rear pattern plate 9 of structural frame is shelved on the rolling element 12 of injection machine support, the rear pattern plate 9 of structural frame is strip hole with the fixing threaded hole 13 of injection machine support, the direction in strip hole and structural frame guide pillar axial direction homophase.The elastic deformation produced after holding guide pillar tension by the gap between strip hole, thus avoid the distortion of structural frame, ensure the depth of parallelism between moving platen and solid plate.
Described moving platen rapid moving mechanism is made up of motor deceleration case 20, the gear 10 be meshed for a pair and tooth bar 7, directive wheel 71, described motor deceleration case 20 is arranged on rear pattern plate 9 dorsal part, gear 10 is arranged on reduction box 20 output shaft, tooth bar 7 one end is fixed on moving platen 5 dorsal part, the other end is shelved on gear 10 through the through hole of rear pattern plate, directive wheel 71 is arranged on the side of rear pattern plate through hole inner chamber hole wall, directive wheel 71 touches with tooth bar 7 dorsal part, and described moving platen rapid moving mechanism has two groups to be symmetricly set on structural frame both sides.Oil cylinder is adopted to be compared with driving force with traditional Injection Motor Template, this structure is without the need to being equipped with the oil pump of large discharge and jumbo fuel tank, again because the friction between moving platen and guide pillar is rolling friction, required drive is minimum, appropriate structural frame is installed to be moved by hand propelled moving platen, therefore simplify mechanism, minimizing energy consumption, achieve beyond thought effect.
Fig. 4 ~ Fig. 5 gives Mode-locking oil cylinder structural scheme of mechanism.In figure, described Mode-locking oil cylinder mechanism is by four oil cylinders 6, locked mode gripper shoe 8 and transmission mechanism, the through hole 91 that rear pattern plate 9 is provided with for the break-through of oil cylinder 6 piston rod forms, described locked mode gripper shoe 8 is in cross, described transmission mechanism is by motor deceleration case 80, the sector 81/82 be meshed for a pair, power transmission shaft 83, position-sensing switch 84/85 forms, described four oil cylinders 6 with moving platen 5 axial line for symmetrical centre is distributed on moving platen 5 dorsal part, power transmission shaft 83 is arranged on rear pattern plate 9 by bearing, locked mode gripper shoe 8 is arranged on the axle that to stretch out outside power transmission shaft 83 on front side of rear pattern plate 9, a pair sector 81/82 is arranged on another axle journal of power transmission shaft 83 of rear pattern plate dorsal part respectively---on motor deceleration case 80 output shaft neck, two described position-sensing switches 84/85 are arranged on criss-cross one of locked mode gripper shoe 8 and refer on the position, the left and right sides of 88 rotary motion trace, described position-sensing switch 85 right lateral position is the through hole 91 for the break-through of oil cylinder 6 piston rod that criss-cross each finger after locked mode gripper shoe 8 is rotated covers in rear pattern plate 9 completely, described position-sensing switch 84 left lateral position is the through hole 91 for the break-through of oil cylinder 6 piston rod that criss-cross each finger after locked mode gripper shoe 8 is rotated opens rear pattern plate 9 completely.For improving the stressed situation of locked mode gripper shoe and transmission mechanism power transmission shaft further, the present invention also takes following measure: locked mode gripper shoe 8 is arranged on the axle that to stretch out outside power transmission shaft 83 on front side of rear pattern plate as to be installed by intermediate plate 87, described intermediate plate 87 1 side end face is directly installed on by screw in the axial end of power transmission shaft 83, its axial line certain radius of intermediate plate 87 opposite side tip to face distance be circumferentially provided with several blind holes, stage clip 86 is provided with in blind hole, locked mode gripper shoe 8 dorsal part compression press spring 86 is fixed on intermediate plate, locked mode gripper shoe 8 and rear pattern plate 9 end face are mutually across a certain distance.When locked mode gripper shoe bears Mode-locking oil cylinder transmitting force, the further compression press spring of locked mode gripper shoe, eliminate described in a determining deviation, be adjacent on rear pattern plate end face, power be passed on rear pattern plate; When after Mode-locking oil cylinder constraint relief, locked mode gripper shoe is separated reset with rear pattern plate, retains certain spacing, alleviates the resistance that locked mode gripper shoe is rotated.
This structure is work like this: moving platen enters the closed position of moving platen and solid plate fast by starting moving platen rapid moving mechanism, the transmission mechanism of locked mode gripper shoe starts subsequently, locked mode gripper shoe is driven to rotate until the cross of locked mode gripper shoe stops operating after respectively referring to cover in completely the through hole for cylinder piston rod break-through of rear pattern plate, then Mode-locking oil cylinder mechanism oil cylinder starts, cylinder piston rod is overhanging until cylinder piston rod and locked mode gripper shoe touch, under the drive of Mode-locking oil cylinder, moving platen and solid plate are completely closed, wait for injection moulding.Otherwise, injection moulding terminates rear cylinder piston rod and returns oil cylinder, the transmission mechanism of locked mode gripper shoe starts, locked mode gripper shoe is driven to rotate until the cross of locked mode gripper shoe stops operating after respectively referring to open completely the through hole for cylinder piston rod break-through of rear pattern plate, then moving platen rapid moving mechanism is started, moving platen is return fast, and the piston rod of oil cylinder, by the through hole of rear pattern plate, is return and do not stopped.The advantage of this structure compared with traditional mechanism is that the plunger of Mode-locking oil cylinder or piston rod do not move when moving platen folding mould moves, and only making micro-stroke when locked mode action can meet the demands, therefore required oil mass is few, only needs a little fuel tank just passable; Rotation due to locked mode gripper shoe provides and allows the support of cylinder piston rod rod end, and substantially reduce the length of guide pillar needed for matched moulds, integral body reduces, and reduces equipment manufacturing cost, the space that the equipment of saving occupies, and is also conducive to transport simultaneously.
Describe embodiments of the present invention by reference to the accompanying drawings above, the structure that embodiment provides is not construed as limiting the invention, and in this area, those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain.
