Description
Technical field
The invention belongs to technical field of buildings, it is related to a kind of mold closing screw for producing pile tube pipe die.
Background technology
Pile tube manufacturing belongs in manufacture type heavy industry production type, the production process of pile tube, and the use to pipe die rises
Very important effect, and pipe die mold closing screw is the position of pipe die most critical, the quality to pile tube plays sizable work
With, when pipe die lacks mold closing screw or unurgent mold closing screw, the defects such as the spillage of pile tube are will result in, so, in pile tube
Industry, is all studied pile tube mold closing screw further.
Chinese patent literature discloses a kind of T-shaped mold closing screw [application number：201020296888.5] by screw rod, spring
Seat, spring, nut composition, accompany spring between spring base and spring base, one end of T-shaped screw rod stretch into successively spring base, spring,
Spring base coordinates with nut again, using the T-shaped mold closing screw, it is not necessary to which special messenger goes a mold closing screw to be suspended to upper mould from lower mould side
Side, will not also cause damage to original equipment when pneumatic impact spanner is urgent, save part labour.The mistake being molded in tubular pile centrifugal
Cheng Zhong, eliminates and there is very big potential safety hazard.But the spring base of the program and nut are not fixedly connected with pipe die, in matched moulds
When such as run into vibrations, spring base, which easily loosens, causes screw rod be connected loosening, generation free travel, so that pipe die generation with nut
Leakage, the matched moulds intensity of the mold closing screw still has much room for improvement.

Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Produce the mold closing screw of pile tube pipe die as shown in figure 1, a kind of, including be used for and upper mould fix upper fixed seat 1
And be used for and lower fixed seat 2 that lower mould is fixed, some screws 3 are respectively equipped with described upper fixed seat 1 and lower fixed seat 2,
Spring 4 is arranged with described upper fixed seat 1, bolt 5, which sequentially passes through to be spirally connected with lower fixed seat 2 after spring 4 and upper fixed seat 1, to be consolidated
It is fixed.
The one end of spring 4 away from upper fixed seat 1 is inserted with a guide sleeve 6, and the end of described spring 4 is resisted against guiding
On the guiding end face 7 of set 6.Bolt 5 includes bolt head 51 and key 52, the connection of described guide sleeve 6 and bolt head 51
Place is provided with can reduce the friction drag reduction mechanism 8 of frictional force when bolt head 51 is rotated and contacted with guide sleeve 6.
Friction drag reduction mechanism 8 can be ball bearing or other bearings, directly in bolt head 51 or can also be oriented to
Ball etc. is embedded on end face 7, for reducing frictional force, the speed that bolt 5 is spirally connected with lower fixed seat 2 is improved.
In the present embodiment, with reference to shown in Fig. 2 and Fig. 4, friction drag reduction mechanism 8 includes being located at guiding end face 7 and/or bolt
Some raised items 9 on 5 heads, the curved strip of raised item 9, it is preferable that be oriented to the projection on end face 7 and/or the head of bolt 5
Bar 9 is uniformly distributed in a ring.
In conjunction with shown in Fig. 3, Fig. 5 and Fig. 6, bolt 5 is to be arranged with one on hexagon socket head cap screw or outer-hexagonal bolt, bolt 5
The individual jump ring 10 that can prevent bolt 5 from departing from upper fixed seat 1, described jump ring 10 is located in upper fixed seat 1, in upper fixed seat 1
With jump ring lock chamber 101, when bolt 5 is moved up and when departing from lower fixed seat 2, by the position-limiting action of jump ring 10, bolt 5
It is always positioned inside upper fixed seat 1, prevents bolt 5 from dropping.
Upper fixed seat 1 is provided with lead 11 close to the side of spring 4, and described spring 4 is set in outside lead 11, described
Lower fixed seat 2 close to the side of upper fixed seat 1 provided with being spirally connected post 12, described bolt 5 and the post 12 that is spirally connected is spirally connected fixation.
Lower fixed seat 2 and the post 12 that is spirally connected is integral type structure or split-type structurals.As shown in figure 5, when lower fixed seat 2 and spiral shell
When connecing post 12 for split-type structural, described lower fixed seat 2 is provided with the post fixing hole 13 that is spirally connected, and the post 12 that is spirally connected snaps onto the post that is spirally connected
In fixing hole 13, there is convenient disassembly.And the lower fixed seat 2 of integral structure and the post 12 that is spirally connected then have structural strength
High advantage.
In matched moulds, lower fixed seat 2 is fixed on lower mould with screw 3, and bolt 5 passes through guide sleeve 6, spring 4 and upper fixation
Jump ring 10 is inserted in so that bolt 5 and upper fixed seat 1 now will in inseparable structure on the key 52 of bolt 5 after seat 1
Upper fixed seat 1 is fixed on mould, and upper fixed seat 1 is corresponding with the position of lower fixed seat 2.During matched moulds, rotating bolt 5 makes spiral shell
Bolt 5 is spirally connected with lower fixed seat 2, during form removal, and same rotating bolt 5 makes bolt 5 be separated with lower fixed seat 2.Either matched moulds is still
Form removal, bolt is all the time on upper fixed seat 1, therefore efficiency is greatly enhanced.Due to upper fixed seat 1 and lower fixed seat 2 with it is upper
Mould is fixedly connected with lower mould, therefore improves the intensity of matched moulds, and bolt 5 will not be made to depart from pipe die.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although more used herein upper fixed seat 1, lower fixed seat 2, screw 3, spring 4, bolt 5, bolt head 51,
Key 52, guide sleeve 6, it is oriented to end face 7, friction drag reduction mechanism 8, raised item 9, jump ring 10, lead 11, the post 12 that is spirally connected, is spirally connected
The terms such as post fixing hole 13, jump ring lock chamber 101, but it is not precluded from the possibility using other terms.Using these terms only
Merely to more easily describing and explaining the essence of the present invention；Being construed as any additional limitation is all and this
What spirit was disagreed.
