Firstly, an operator installs the equipment on an injection molding machine through a glue scraping mechanism 9, the glue scraping mechanism 9 is connected with a driving device, a feeding pipe 2 is externally connected with a solvent colloid, the operator can place a mold below a glue outlet 3 and then discharge the solvent colloid into the feeding pipe 2, the solvent colloid in the feeding pipe 2 is discharged into a rubber pipe 1, when a proper amount of solvent colloid is in the rubber pipe 1, the discharging is stopped, the driving device can be started to drive the glue scraping mechanism 9 to move downwards, the glue scraping mechanism 9 moves downwards to drive a cylindrical push block 4 to move downwards, the cylindrical push block 4 moves downwards to drive a first alloy piston 5 to move downwards, the first alloy piston 5 moves downwards to push the solvent colloid in the rubber pipe 1 to be discharged through the glue outlet 3, the solvent colloid drops into a mold product, meanwhile, the cylindrical push block 4 moves downwards to scrape the solvent colloid remained on the inner wall of the rubber pipe 1 into a material storage tank 6, so can prevent that the solute colloid from remaining and leading to extravagantly in rubber tube 1, the solute colloid in stock chest 6 passes through feed port 7 and drops to cylinder ejector pad 4 in, when having the appropriate amount solute colloid on the mould, can start drive arrangement and drive and scrape gluey mechanism 9 rebound and drive cylinder ejector pad 4 rebound, cylinder ejector pad 4 drives first alloy piston 5 rebound, and then scrape gluey mechanism 9 rebound and pass through check valve 81 with the solute colloid in the cylinder ejector pad 4 and push into rubber tube 1 in, and simultaneously, still through inlet port 8 with the air suction stock chest 6 in, after cylinder ejector pad 4 rebound, close drive arrangement, cylinder ejector pad 4 also stop moving. When the sol is required to be sprayed into the mold, the operation is carried out according to the above steps.
Initially, the first spring 97 is in a stretching state, when the frame 91 is installed on an injection molding machine, the guide rod 93 can be connected with the driving device, and further when a mold is placed below the glue outlet 3 and a proper amount of sol is discharged in the rubber hose 1, the driving device can be started to drive the guide rod 93 to move downwards, the guide rod 93 moves downwards to drive the cylindrical push block 4 to move downwards, and further drive the first alloy piston 5 to move downwards to push out the sol to be sprayed in the mold, meanwhile, the guide rod 93 moves downwards and further drives the sliding sleeve 95 to move downwards through the connecting rod 94, the sliding sleeve 95 moves downwards and drives the hollow slide rod 96 to move downwards through the first spring 97, and due to the action of the first spring 97, the hollow slide rod 96 drives the second alloy piston 98 to move upwards to reset, and similarly, when a proper amount of sol is sprayed in the mold, the driving device is started to drive the guide rod 93 to move upwards and further drive the first alloy piston 5 to move upwards, meanwhile, the hollow slide rod 96 is driven to move upwards, the hollow slide rod 96 is blocked when moving upwards and contacting with the rack 91, the second alloy piston 98 stops moving, the sliding sleeve 95 continues to move upwards to enable the first spring 97 to be stretched, when the cylindrical push block 4 moves upwards and resets, the second alloy piston 98 pushes the solvent colloid in the cylindrical push block 4 into the rubber tube 1 through the one-way valve 81, and when the first alloy piston 5 moves upwards and resets, the driving device is closed.
Initially, the blocking rod 109 is clamped into the clamping groove 1010 to fix the blocking rod 102, the second spring 103 is in a compressed state, when the cylindrical push block 4 moves upwards, the cylindrical push block 4 moves upwards to drive the inclined block 1014 to move upwards, when the inclined block 1014 moves upwards to contact with the guide wheel 1013, the inclined block 1014 enables the guide wheel 1013 to move outwards, the guide wheel 1013 moves outwards to drive the cross rod 1012 to move outwards, the cross rod 1012 moves outwards to drive the movable rod 105 to move outwards, the third spring 107 stretches, the movable rod 105 moves outwards to drive the blocking rod 109 to move outwards, the blocking rod 109 moves outwards to be separated from the clamping groove 1010, the blocking rod 102 moves downwards to block the feeding hole 7 under the action of the second spring 103, and further when the second alloy piston 98 pushes out the sol in the cylindrical push block 4, the sol cannot be pushed into the feeding hole 7, and when the cylindrical push block 4 continues to move upwards to reset, the cylindrical push block 4 also drives the blocking rod 102 to move upwards, second spring 103 compresses, and when putty pole 102 rebound made draw-in groove 1010 move to draw-in groove 109 inboard, because of the effect of third spring 107, movable rod 105 inwards moved and drives draw-in groove 109 inward movement and insert in draw-in groove 1010, and then draw-in groove 109 and draw-in groove 1010 cooperation are fixed with putty pole 102, and when cylinder ejector pad 4 moved down, cylinder ejector pad 4 made putty pole 102 break away from with feed port 7. In this way, the second alloy piston 98 is prevented from pushing a portion of the sol into the feed hole 7.
After the device is used, an operator can pull the baffle 17 to swing upwards to open, then the baffle 17 does not block the first opening 16, the contact block 13 can be pulled to move upwards, the contact block 13 moves upwards to drive the contact rod 12 to move upwards, the contact rod 12 moves upwards to drive the sliding block 14 to move upwards, the sliding block 14 moves upwards to drive the annular scraping blade 15 to move upwards, and the annular scraping blade 15 moves upwards to scrape off residual solvent colloid on the inner wall of the cylindrical push block 4. When the annular scraping blade 15 moves upwards to the maximum stroke, the solvent colloid drops out of the cylindrical pushing block 4, the contact block 13 is pushed to move downwards to drive the contact rod 12 to move downwards, the contact rod 12 drives the annular scraping blade 15 to move downwards through the sliding block 14 to reset, the contact block 13 stops being pushed, and the pushing baffle 17 swings downwards to reset. Therefore, the influence of the residual mass of the sol on the movement of the second alloy piston 98 can be prevented.
When the cylindrical push block 4 moves downwards, the second alloy piston 98 pumps air into the storage tank 6 through the air inlet hole 8, the filter cotton 20 filters the air, and the filtered air is pumped into the storage tank 6. After the filter cotton 20 is used for a long time, an operator can pull the net-shaped cover plate 21 out of the net-shaped hollow cylinder 19, take out the filter cotton 20, place new filter cotton 20 into the net-shaped hollow cylinder 19, and plug the net-shaped cover plate 21 back into the net-shaped hollow cylinder 19. Thus, impurities in the air can be prevented from affecting the quality of the sol.
Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
