Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model being further illustrated, the content of embodiment is not as the restriction to protection domain of the present utility model.
Fig. 3 illustrates the three-dimensional, exploded view of the shaped platform with sealing device of the present utility model. As it is shown on figure 3, similar with existing shaped platform, the shaped platform 1 with sealing device of the present utility model includes shaped platform lower plate 15, shaped platform upper plate 13 and the print platform 12 being fixed on the upper surface of described shaped platform upper plate 13.
Wherein, from existing shaped platform adopt square seal ring carry out seal different, in this utility model, as shown in Figure 4, described shaped platform lower plate 15 be all around wound with a circle felt bar 18. Surrounding inside described felt bar 18 is respectively arranged with a top board 19. Described top board 19 is movable to be arranged, and it can felt bar 18 described in pushing tow outward. Further, four interior angle places of described felt bar 18 are respectively arranged with a fillet jacking block 17. The rounded shape in one end towards described felt bar 18 of described fillet jacking block 17, fits with four fillets with molding bucket outer frame body 3 described later. As shown in Figure 4, wherein, four described top boards 19 form unfilled corner tetragon, and four described fillet jacking blocks 17 lay respectively at four unfilled corner places of described unfilled corner tetragon.
The surrounding of the upper surface of described shaped platform lower plate 15 is respectively fixed with a spring location-plate 21. Preferably, each described spring location-plate 21 is equal apart from the distance of the side of described shaped platform lower plate 15. As shown in Figure 4, four described spring location-plates 21 form an airtight tetragon. Described spring location-plate 21 is positioned at described top board 19 described spring location-plate 21 and described top board 19 one_to_one corresponding.
Wherein, it is both provided with multiple compression spring 20 between each described top board 19 with each corresponding described spring location-plate 21 and between each described fillet jacking block 17 and described spring location-plate 21, is also both provided with a compression spring 20. Preferably, it is provided with multiple locating slot in the lateral surface of described spring location-plate 21. One end of described compression spring 20 is positioned at described locating slot. In such manner, it is possible to realize the location of described compression spring 20, it is prevented that it comes off or channels bit. Described compression spring 20 can top board 19 and fillet jacking block 17 described in pushing tow, and by felt bar 18 described in described top board 19 and fillet jacking block 17 pushing tow, realize the sealing between shaped platform 1 and molding bucket outer frame body 3 thereby through described felt bar 18.
Described shaped platform upper plate 13 is fixed on described spring location-plate 21, to realize the connection between described shaped platform upper plate 13 and described shaped platform lower plate 15. Preferably, as it is shown on figure 3, described shaped platform upper plate 13 is fixed on described spring location-plate 21 by multiple screws 14. So so that between described shaped platform lower plate 15 and shaped platform upper plate 13, assembly and disassembly are convenient, quick.
Additionally, in this utility model, it is preferable that the downside of described shaped platform lower plate 15 is provided with the pin-and-hole 16 being connected with lower support system 2. So, described shaped platform 1 can be connected with lower support system 2 by described pin-and-hole 16, consequently facilitating drive described shaped platform 1 to move up and down in molding bucket outer frame body 3.
In use, described shaped platform lower plate 15 is placed in molding bucket outer frame body 3, and supports by frock below described shaped platform lower plate 15. Then, described spring location-plate 21 is arranged on the upper surface of shaped platform lower plate 15, by the felt bar 18 that cuts along molding bucket outer frame body 3 surrounding winding forming. Then, top board 19, fillet jacking block 17 are placed in shaped platform lower plate 15, compression spring 20 is sequentially arranged in the locating slot of spring location-plate 21. Wherein, the fillet of fillet jacking block 17 ensures four fillet consistent size with molding bucket outer frame body 3, and fillet jacking block 17 withstands on felt bar 18, and felt bar 18 will deform upon so that it is fit completely with four fillets of molding bucket outer frame body 3. So, withstanding on felt bar 18 by compressing the elastic force of spring 20 by top board 19 and fillet jacking block 17, pressing and extruding felt bar 18 makes it be close to four faces of molding bucket outer frame body 3 and four fillets, plays sealing function. Afterwards, with screw 14, shaped platform upper plate 13 is fixed on spring location-plate 21. Finally, print platform 12 is fixed on shaped platform upper plate 13. So, the installation of described shaped platform 1 is just completed.
Afterwards, as illustrated in fig. 1 and 2, lower support system 2 is connected with the shaped platform lower plate 15 of shaped platform 1 by pin-and-hole 16. Lower support system 2 and connecting plate 9 are fixed by screw. Connecting plate 9 is fixed by screws on the guide pin bushing 11 being positioned at outside molding bucket outer frame body 3. Wherein, the sidepiece of molding bucket outer frame body 3 is provided for the vertical holes of described connecting plate 9 traverse, in order to described connecting plate 9 moves up and down.Guide pin bushing 11 is set on guide rod 10, and guide pin bushing 11 is connected with ball screw assembly, 4. Driven gear 8 is fixed on the lower end of ball screw assembly, 4, and driving gear 7 is connected with decelerator 6, and decelerator is connected with motor 5. Motor 5 drives decelerator 6 to rotate, and drives driving gear 7 and driven gear 8 to rotate by decelerator 6. The rise and fall campaign rotarily driving ball screw assembly, 4 of driven gear 8. Ball screw assembly, 4 drives guide pin bushing 11 to move up and down on guide rod 10, and drives connecting plate 9 to slide up and down by guide pin bushing 11. So, lower support system 2 follows connecting plate 9 and guide pin bushing 11 moves up and down. Owing to shaped platform 1 is connected by pin-and-hole with lower support system 2, thus driving shaped platform 1 to do integral elevating motion.
Shaped platform of the present utility model have employed a kind of new sealing device and replaces customization sealing ring, and simple in construction, cost of manufacture is low. And after felt bar weares and teares, there is automatic compensating action, favorable sealing property under the effect of compression spring force, stablize, it is not necessary to frequently change.
Above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to embodiment of the present utility model. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here cannot all of embodiment be given exhaustive. Every belong to apparent change that the technical solution of the utility model extended out or the variation row still in protection domain of the present utility model.
