Abstract
The utility model discloses a mouth flaring mould core, which is characterized in that the mouth flaring mould core comprises a plurality of flaring blocks with sector section, each flaring block is formed by a working part and a connecting part, the working part and the connecting part are arranged in step shape, a sliding groove is arranged on the connecting part, an inclined surface is arranged on the internal side wall of each flaring block, a clearance is kept between every two flaring blocks, and after the flaring blocks are arranged on the same circumference, a tampered hole for inserting a driving shaft is formed in the middle of the circumference. The utility model has the advantages that the operation is convenient, the design and the matching of the dimension and the angle of the mouth flaring mould core are ideal, and the production efficiency and the precision of pipe fittings are greatly improved.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of bloated mouthful of core rod.
Background technology
Pvc pipe road in pipe fitting in the pipeline of automobile, air-conditioning or the architectural engineering, its pipe end all will form through rise pipe or draw operation.In the plumber's preface that rises, mouthful core rod that expands is one of part important in the bulging mould, its dimensional accuracy and angle are very important, can it directly has influence on the piece that expands distending, whether flexible, and can the oral thermometer face that expand behind the distending slick and slyly engage the projection that formation is slick and sly if moving, expand in the prior art mouthful core rod size and angle design cooperate not ideal enoughly, can not obtain accurate pipe fitting.
The utility model content
The utility model provides a kind of size and angle design a reasonably bloated mouthful core rod at the weak point of above-mentioned technology.
The realization the technical solution of the utility model is as follows:
A kind of bloated mouthful of core rod, comprise that a plurality of cross sections are the bloated piece of fan shape, these bloated pieces are made up of operate portions and connecting portion, operate portions and connecting portion are step-like layout, wherein connecting portion is provided with chute, the internal face of each bloated piece is an inclined-plane, expands in twos and leaves the gap between the piece, and these bloated pieces are arranged in back taper hole that supplies driving shaft to insert of formation in the middle of this circumference on the same circumference.
The outside wall surface of the operate portions of described bloated piece is provided with projection,
The outside wall surface of the operate portions lower end of described bloated piece is the chamfering setting.
Projection on the outside wall surface of described operate portions is positioned at the root of this operate portions, and this projection is made up of curved portions and rake.
The covering of the fan radian of described bloated piece is between 45 °～60 °.
The gap of described adjacent bloated interblock is between 3～6mm.
The gradient on the inclined-plane of described bloated piece is between 80 °～100 °.
The beneficial effects of the utility model are: easy to operate, mouthful core rod that expands size and angle design cooperate desirablely, improved the production efficiency and the precision of pipe fitting greatly.
