Abstract
The invention discloses a loose core type mould which comprises an outer mould, an inner mould and a positioning locking device, wherein the inner mould is arranged in the inner cavity of the outer mould; an inner locking wedge block is arranged on the external surface of the inner mould; an outer locking wedge block which is matched with the inner locking wedge block is arranged on the internal surface of the outer mould; and the inner mould is positioned and locked with the outer mould through the positioning locking device. The loose core type mould has the advantages that the structure is reasonable, the mould does not need to be hung and moved by using a crane in the whole production line, the mould is suitable for the allocation of flow line production, the labor intensity is reduced, and the production cost is saved.
Description
Technical field
The present invention relates to a kind of mould, is a kind of Drawing-Core mould specifically.
Background technology
At present in the pile tube manufacturing mould of used manufacturing pile tube all by on cover mold and lower cover mould form, all lock during the cover mold matched moulds up and down in process of production with the screw rod nut, when the tie down screw nut, all be to operate with the strong wind big gun, this action need expends very strong labour, and this can not adapt to the supply and demand ability in the current mode of production and social labor power market; And screw rod nut frequency of utilization height, being easy to damage, this just causes the consumption of screw rod nut very big.Need after cloth finishes to sling mould to next station with loop wheel machine, this process just needs very big space, and very occupied ground if still adopt the mode of existing lifting, makes that automatic assembly line layout difficulty is big, and the production safety management difficulty is big.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome weak point of the prior art, a kind of Drawing-Core mould of rational in infrastructure, handled easily is provided.
Technical scheme: for realizing above-mentioned technical problem, the technical solution used in the present invention is: a kind of Drawing-Core mould, comprise external mold, internal mold and positioning and locking device, described internal mold is located in the inner chamber of external mold, locking contract piece is provided with on the inner surface of described external mold and the suitable outer locking contract piece of interior locking contract piece in being provided with on the outer surface of described internal mold; Described internal mold is by positioning and locking device and external mold positioning and locking.
Operation principle of the present invention: internal mold is done relative horizontal rectilinear motion in external mold, and the moment that the inclined-plane produced by interior outer locking contract piece makes internal mold with external mold locking with separate.
Described positioning and locking device is the positioning and locking screw rod; Tail end at described internal mold is provided with the first location pilot hole, be provided with on described external mold and the corresponding second location pilot hole in pilot hole position, first location, described positioning and locking screw rod after inserting the first location pilot hole, the second location pilot hole is successively locked described internal mold and external mold.
Directly to be rolled to the centrifugal displacement of need not slinging on the centrifuge in order making after finishing cloth, also to be provided with centrifugal running wheel in the outside of described external mold.
Described internal mold is identical with the external mold shape during locking.
Beneficial effect: compared with prior art, advantage of the present invention is: rational in infrastructure; Mould need not to be fit to the streamline production distribution with the loop wheel machine mobile station of slinging in the whole production flow process, and can reduce working strength of workers, saves production cost.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is done further explanation.
As depicted in figs. 1 and 2, a kind of Drawing-Core mould comprises external mold 1, internal mold 2 and positioning and locking device 3, and internal mold 2 is located in the inner chamber of external mold 1, locking contract piece 4 in being provided with on the outer surface of internal mold 2 is provided with the outer locking contract piece 5 suitable with interior locking contract piece 4 on the inner surface of external mold 1; Also be provided with centrifugal running wheel 6 in the outside of external mold 1; In external mold 1 inner chamber, be provided with anchor point; Wherein positioning and locking device 3 is the positioning and locking screw rod, tail end at internal mold 2 is provided with the first location pilot hole, on external mold 1, be provided with and the corresponding second location pilot hole in pilot hole position, first location, when internal mold 2 moved to anchor point, the positioning and locking screw rod after passing the first location pilot hole, the second location pilot hole was successively locked internal mold 2 and external mold 1.Internal mold 2 is identical with external mold 1 shape during locking.
Before the locking, internal mold 2 is the U type; When internal mold 2 moves to anchor point in the external mold 1, the inclined-plane of interior locking contract piece 4 overlaps fully with the inclined-plane of outer locking contract piece 5, make internal mold 2 closed and locked and form a spue line, this moment, internal mold 2 was the O type, and then loaded onto the positioning and locking screw rod with internal mold 2 and external mold 1 positioning and locking.After the locking, by cloth tube linear uniform motion cloth in internal mold 2, finish cloth after this mould directly be rolled on the centrifuge centrifugal; Unclamp the positioning and locking screw rod after the pile tube manufacture process finishes, internal mold 2 is ejected with hydraulic jack to external mold 1 Way out and depart from anchor point, this moment, internal mold 2 openings and separated with the pile tube body, ejected the pile tube goods at last, and whole process of production is finished.After adopting this mould, do not need the displacement of slinging in whole process of production, safety has obtained guarantee.
Among the present invention, interior locking contract piece 4 preferably is welded on the both sides of internal mold 2 spue lines, can make internal mold 2 closed fully when locking like this.
The shape of this mould can be designed to polygon or circle according to producing needs.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
