Description
Technical field
The present invention relates to the mould emptier of female branch tee pipe joint mould, belong to the mould of plastics field.
Background technology
Because low cost, high efficiency that plastic is produced become inevitable trend to mould Dai Gangyi.Therefore replace cast iron, coupling also just to take exception to joint for plastic tube (for example female branch tee pipe joint).And the production of plastic must be based on mould, so carry out and take off the screw thread Study on Technology in the multi-faceted mould automatically, reduce mould and manually take off screw thread labour intensity outward, improve mould production efficiency and injector utilization rate, and all significant to the exploitation of taking off threaded mold in the mould automatically.
Summary of the invention
The objective of the invention is the internal thread fuse of tee pipe coupling to be deviate from automatically smoothly, enhance productivity, reduce the outer artificial labour intensity of mould, cost-effective female branch tee pipe joint mold releasability mechanism in order to provide a kind of mould by three somatotypes.
The technical scheme of female branch tee pipe joint mold releasability of the present invention mechanism is: comprise base plate and panel, base plate connects cushion block through guide pillar, back mold shaft board, back model cavity plate and back mode-gear plate, panel connects front mould chain wheel plate through guide pin bushing, the front mould gear plate, front mould shaft bearing plate and front mould cavity plate, guide pillar matches with guide pin bushing, hot mouth is installed in the panel, form die cavity between back model cavity plate and the front mould cavity plate, hot mouth is communicated with die cavity, the female branch tee pipe joint that moulding is arranged in the die cavity, it is characterized in that installing on the described base plate back mould central shaft, back template strand wheel and back mould central gear are installed on the back mould central shaft, back mould central gear connects back mould screw thread fuse, and the head of back mould screw thread fuse contacts with the back internal thread of female branch tee pipe joint; Described hot mouth is installed the front mould central shaft outward, and front mould sprocket wheel and front mould central gear are installed on the front mould central shaft, and the front mould central gear connects front mould screw thread fuse, and the head of front mould screw thread fuse contacts with the preceding internal thread of female branch tee pipe joint; Inner slide and outer slide are installed in the described front mould cavity plate and the model cavity plate outside, back, the slide block central shaft is installed in the outer slide, the slide block central gear is installed on the slide block central shaft, the slide block central gear connects slide block screw thread fuse, and slide block screw thread fuse contacts with the side internal thread of female branch tee pipe joint; Described front mould shaft bearing plate connects the slide block lock dog down, be shaped on the lock dog inclined-plane on the outer slide, the lock dog inclined-plane matches with the slide block lock dog, the outer slide outer wall is installed the slide block oil motor, the slide block oil motor connects the slide block central shaft, and contiguous block is installed in the outer slide bottom surface, in the bottom surface of back mode-gear plate the slide block oil cylinder is installed, the piston rod of slide block oil cylinder connects contiguous block, is equipped with the twice parting assembly between front mould chain wheel plate and outer slide outer wall.
Female branch tee pipe joint mold releasability of the present invention mechanism, during die sinking, because of the effect of twice parting assembly, mould carries out the somatotype first time earlier, and the twice parting assembly is broken away from, and the injector die sinking stops.At this moment, drive the front mould sprocket rotation by injector power, the front mould sprocket wheel drives the front mould central shaft, the front mould central shaft drives the front mould central gear, the front mould central gear drives front mould screw thread fuse and rotates, because front mould screw thread fuse rotates the acting in conjunction of the reaction force and the front mould pre-compressed spring spare that take off screw thread, front mould gear plate, front mould shaft bearing plate shrink back, the preceding internal thread of extracting front mould screw thread fuse and female branch tee pipe joint out breaks away from, and realizes the somatotype second time of mould.Injector continues die sinking, and back model cavity plate is realized the somatotype for the third time between the forward and backward mould of mould along with the action of injector retreats into the end.At this moment be installed in the slide block oil motor work on the outer slide, drive the slide block central gear by the slide block central shaft, the slide block central gear drives slide block screw thread fuse and rotates, because slide block screw thread fuse rotates the acting in conjunction of the reaction force and the sliding block prepressing spring part that take off screw thread, inner slide and outer slide shrink back, and the side internal thread of extracting slide block screw thread fuse and female branch tee pipe joint out breaks away from.Then, the slide block oil cylinder that is fixed on the mode-gear plate bottom surface, back moves outward by contiguous block promotion outer slide.Then, injector power drives back template strand wheel and rotates, back template strand wheel drives back mould central shaft, back mould central shaft drives back mould central gear, back mould central gear drives back mould screw thread fuse and rotates, because back mould screw thread fuse rotates the reaction force that takes off screw thread and ejects the female branch tee pipe joint, realize taking off screw thread automatically in the mould thread core submodule of back, take out by manipulator at last.Then, slide block oil cylinder pulling inner and outer slider resets.Injector can begin matched moulds, by the effect of slide block lock dog, inner and outer slider is resetted again.Then, mould at somatotype place for the third time, for the second time the somatotype place, the somatotype place is closed in succession for the first time, carries out next circulation through high-voltage lock mould, injection moulding, pressurize, preformed, cooling.This programme deviates from the internal thread fuse of tee pipe coupling by three somatotype demouldings automatically smoothly, enhances productivity, and reduces the outer artificial labour intensity of mould, saves cost, has the good effect of highly significant.
Female branch tee pipe joint mold releasability of the present invention mechanism; described twice parting assembly comprises and is installed in fixture block in the front mould gear plate outer wall that fixture block has the compression spring, on the outer slide outer wall pull bar is installed; on the front mould chain wheel plate outer wall briquetting is installed, briquetting and pull bar match with fixture block.During die sinking, move on the briquetting and push down fixture block, make in the fixture block and contract, fixture block and pull bar disengage, and die sinking is smooth.The slide block pin is installed in the described slide block screw thread fuse, pin spline pin is installed in the outer slide, pin spline pin matches with the slide block pin, because slide block screw thread fuse needs to bump extremely with front mould screw thread fuse sidewall arc surface during injection mo(u)lding, therefore also need the slide block pin in the slide block screw thread fuse, the slide block pin does not change when making the rotation of slide block screw thread fuse take off screw thread, and assurance slide block pin and front mould screw thread fuse are intact to be bumped extremely.
