In use, the built-in brake spring 8-2 of mode transfer brake motor 8 presets certain compression stress, brake piston 8-3 is made to compress disk brake pad 8-4 under spring force, disk brake pad 8-4 produces static torque under the effect of frictional force, thus make output shaft 8-5 be in on-position, be now with the Y-valve 13 of meta off-load function to be in unloading condition, when injection machine needs mode transfer precession to do, the left electromagnet 208 of Y-valve 13 obtains electric, spool in electromagnetic force lower slider to left electromagnet 208 one end, pressure oil enters Y-valve 13 from P mouth, shuttle valve 12 is connected to by the second oil pipe 27, the steel ball 12-1 entered in shuttle valve 12 Hou mono-tunnel control oil promotion shuttle valve 12 moves to right-hand member and is shut by shuttle valve 12 home loop, now control oil and enter unlatching chamber 8-6 from shuttle valve 12 meta by brake circuit 20 and joint 17, produce an opening pressure contrary with tripping spring 8-2 active force, act on brake piston 8-3 and overcome default tripping spring 8-2 compression stress, when opening pressure is greater than the compression stress of tripping spring 8-2, thrust on disk brake pad 8-4 reduces gradually, now a road hydraulic oil enters gerotor motor 8-1 by the first loop 28 and the second hydraulic fluid port 16, make it the turning moment produced under the driving of hydraulic oil, when this turning moment is greater than the static torque of disk brake pad 8-4 generation, then motor output shaft 8-5 starts to turn clockwise, mode transfer pinion 21 is driven to rotate, and then drive mode transfer bull gear 2 to rotate, final drive 4 mode transfer screws 5 rotate along pull bar 6 and form mode transfer action forward, now gerotor motor 8-1 reuse mouth enters shuttle valve 12 by second servo loop 29, then enters Y-valve 13 from the first hydraulic fluid port 15 by the first oil pipe 14, lets out in fuel tank eventually through T mouth.Electromagnet power-off at the end of mode transfer, the spool of Y-valve 13 is reset to meta under spring force, now mode transfer brake motor 8 and shuttle valve 12, first hydraulic fluid port 15, second hydraulic fluid port 16 connect fuel tank, steel ball 12-1 is in centre, the obstructed oil of brake circuit 20, therefore brake piston 8-3 promotes disk brake pad 8-4 and compresses under tripping spring 8-2 effect, produces specified static torque and output shaft 8-5 is maintained static reliably, thus define brake force.
Operation principle when mode transfer moves back is substantially identical with above-mentioned, during mode transfer, the right electromagnet 209 of Y-valve 13 obtains electric, spool in electromagnetic force lower slider to right electromagnet 209 one end, pressure oil enters Y-valve 13 from P mouth, shuttle valve 12 is connected to by the first oil pipe pipe 14, the steel ball 12-1 entered in shuttle valve 12 Hou mono-tunnel control oil promotion shuttle valve 12 moves to left end and is shut by shuttle valve 12 home loop, now control oil and enter unlatching chamber 8-6 from shuttle valve 12 meta by brake circuit 20 and joint 17, produce an opening pressure contrary with tripping spring 8-2 active force, act on brake piston 8-3 and overcome default tripping spring 8-2 compression stress, when opening pressure is greater than tripping spring 8-2 compression stress, thrust on disk brake pad 8-4 reduces gradually, now a road hydraulic oil enters gerotor motor 8-1 by second servo loop 29 and the first hydraulic fluid port 15, make it the turning moment produced under the driving of hydraulic oil, when this turning moment is greater than the static torque of disk brake pad 8-4 generation, then motor output shaft 8-5 starts to be rotated counterclockwise, mode transfer pinion 21 is driven to rotate, and then drive mode transfer bull gear 2 to rotate, final drive 4 mode transfer screws 5 rotate along pull bar 6 and form mode transfer action forward, now gerotor motor 8-1 reuse mouth enters shuttle valve 12 by the first loop 28, then enters Y-valve 13 from the second hydraulic fluid port 16 by the second oil pipe 27, lets out in fuel tank eventually through T mouth.Electromagnet power-off at the end of mode transfer, the spool of Y-valve 13 is reset to meta under spring force, now mode transfer brake motor 8 and shuttle valve 12, first hydraulic fluid port 15, second hydraulic fluid port 16 connects fuel tank, brake piston 8-3 promotes disk brake pad 8-4 and compresses under spring 8-2 effect, producing specified static torque makes output shaft 8-5 maintain static reliably, thus define brake force pinning mode transfer pinion 21 and then force fixing mode transfer bull gear 2 to make it not rotate action, thus eventually through the engagement between gear limit assembly such as mode transfer such as mode transfer screw 5 grade rotation loosen, play restriction mode transfer structure in process of production due to motor internal leakage, the mode transfer that hydraulic circuit is revealed and the lower mode transfer screw 5 produced of machine vibration impact rotates and causes loosens.
A kind of braking anti-loose structure for hydraulic injection molding machine formula gear mould adjusting mechanism of the utility model; solve in original hydraulic motor mould adjusting mechanism and loosen because motor internal leakage, hydraulic circuit leakage and the lower mode transfer gear produced of machine vibration impact rotate the mode transfer caused; make the stability of injection machine, reliability improves greatly; the method result is compact simultaneously; install, transformation is convenient, with low cost, braking is reliable.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
