Production efficiency.
Embodiment 1:A kind of mold for concrete wire pole production, referring to Fig. 1 to Fig. 8.
It includes the upper mold 1 and lower mold 2 of the equal semicircular in shape in section, is formed after upper mold 1 and the docking of lower mold 2 interior
Portion's cavity is matched with the shape of concrete wire pole;The both side ends of upper mold 1 are equipped with respectively along the setting of upper mold length direction
Upper ear plate 3, the both side ends of lower mold 2 are equipped with the lower ear plate 4 along the setting of lower mold length direction respectively.
In the design, one-to-one upper perforation 14, lower perforation 13 are respectively equipped on the upper ear plate 1 and lower ear plate 2, when
After upper mold 1 and about 2 lower mold dock, 4 face contact of upper ear plate 3 and lower ear plate, at this point, the upper perforation 14, lower perforation 13
It corresponds, meanwhile, the aperture of the upper perforation 14 is greater than the aperture of the lower perforation 13, and on the inner wall of the lower perforation 13
Equipped with internal screw thread.
Further, a screw rod 5 is respectively equipped with above the upper ear plate 3 of 1 left and right sides of upper mold, the screw rod 5 is logical
The bearing 6 for crossing both ends is arranged on the side wall of upper mold 1, and one end of the screw rod extends to the outside of mold, and extends to mould
Screw rod end outside tool is in positive rib body shape, if interval has several to be consolidated upper ear plate 3 and lower ear plate 4 on the screw rod 5
Fixed clamp device.
Specifically, the clamp device includes the casing 12 that docking is fixed on the peripheral upper ear plate 1 of perforation 14, casing 12
It is embedded in and swivel bearing 19 is installed, further include driven wheel of differential 11, revoling tube 18,11 sets of driven wheel of differential in revoling tube
18 upper end is simultaneously fixed therewith, and the lower end of the revoling tube 18 is mounted in the inner ring of swivel bearing 19, and from mantle
Gear 11 can be rotated by swivel bearing 19.
It further, further include the drive bevel gear 7 that is mounted on screw rod 5 and can be rotated with screw rod 5, the active conical tooth
Wheel 7 and 11 engaged transmission of driven wheel of differential, are also equipped with a guide sleeve 10 in the surface for being located at driven wheel of differential 11, draw
Guide sleeve cylinder 10 is fixed on the side wall of upper mold 1 by fixed plate, and internal screw thread is equipped in guide sleeve 10.
It further include bolt 8, at least two stress ribs 17 being provided symmetrically in the middle part of sliding channel of the bolt 8, institute
The inner wall for stating revoling tube 18 is equipped with and the one-to-one guiding groove 21 of the 17 number same position of stress rib, guidance
Slot 21 runs through the both ends of revoling tube 18.
Further, limit plate 9 is equipped at the top of the bolt 8 above guide sleeve 10, the middle and upper part of the bolt 8 is set
There is the first external screw thread 16, the lower end of the bolt 8 is equipped with the second external screw thread 15, meanwhile, the lower end of the bolt is tapered.
During installation, the bolt 8 is located at turnbarrel 18, in guide sleeve 10, at this point, stress rib 17 corresponds
In guiding groove 21, in screw motion, when the lower end of the bolt 8 is separated with lower perforation 13, first external screw thread
16 are threadedly coupled with the internal screw thread in guide sleeve 10, when the bolt is downwardly into lower perforation 13, the second outer spiral shell
Line 15 is threadedly coupled with lower perforation 13, at this point, first external screw thread 16 is separated with the internal screw thread in guide sleeve.
The mold of the design is when in use:
1, upper mold is buckled on lower mold after skeleton being placed in lower mold;
2, a sleeve is arranged on the screw rod end for extending to mold exterior(The prior art), the electric drill or spiral shell of sleeve and outside
The connection of bolt motor(The prior art), rotary screw rotates later;
3, before screw rod rotation namely when original state, as shown in figure 4, at this point, in the first external screw thread 16 and guide sleeve 10
Internal screw thread be threadedly coupled, the lower end of bolt is located in upper perforation and separates with lower perforate, under being greater than due to the aperture of upper perforation
The aperture of perforation, therefore, bolt lower end at this time are not contacted with upper perforation inner wall;At this point, bolt by the first external screw thread with
The threaded connection of guide sleeve guarantees the relatively fixed of bolt, and is unlikely to fall downwards.
When screw rod rotation, power when screw rod rotates is rotated by active conical tooth wheel drive driven wheel of differential, and driven
While bevel gear rotates, the turnbarrel being fixedly connected with driven wheel of differential telemechanical in swivel bearing, and due to bolt side
Stress rib on wall is in guiding groove 21, therefore, can then drive stress rib to turn by driven wheel of differential rotation
It is dynamic, and then the rotation of bolt is driven, when bolt rotates, due to the reason that the first external screw thread is threadedly coupled with guide sleeve, bolt
To move down, meanwhile, stress rib slides in guiding groove 21, at this point, bolt relative rotation sleeve moves down, finally by
Fig. 4 state is to state transformation shown in Fig. 5.
When carrying out above-mentioned movement, downwards due to bolt rotation, hereafter, the second externally threaded lower end enters in lower perforation,
Then the second external screw thread is connect with lower perforated thread, at this point, the first external screw thread is removed out of guide sleeve, bolt and guide sleeve
Threaded connection relation is released, bolt is slidably connected with guide sleeve realization;And continue to move down with bolt, limit plate 9
To be against on the upper surface of guide sleeve, at this point, the second external screw thread continues to keep connecting with lower perforated thread, with bolt after
Continuous rotation, limit plate consolidate one guide sleeve, upper mold downward pressure to realize to upper mold and lower mold
Fixed, end-state can be found in shown in Fig. 6, and during above-mentioned movement, stress rib is always positioned in guiding groove simultaneously
The rotation of bolt is driven, and when needing to separate upper/lower die, it is only necessary to contra rotating screw.
What the embodiment of the present invention was announced is preferred embodiment, and however, it is not limited to this, the ordinary skill people of this field
Member, easily according to above-described embodiment, understands spirit of the invention, and make different amplification and variation, but as long as not departing from this
The spirit of invention, all within the scope of the present invention.
