Abstract
The invention provides a separating binding post for mold core locating of a polyethylene electro-fusion pipe fitting. The separating binding post comprises a conducting column and a base body, and is characterized in that the base body is provided with a wiring groove and a locating groove; a wire passing hole is formed in the wiring groove; the bottom of the base body is provided with a locating pin groove; a locating pin is arranged in the locating pin groove; the lower portion of the locating pin is matched with a locating hole in a mold core of an injection molding machine. According to the separating binding post for mold core locating of the polyethylene electro-fusion pipe fitting, a resistance wire penetrates through the wiring groove and then is rotated and wound, operation is convenient, it is not required that an operator grips pliers to clamp the base body and enable the base body and the resistance wire to be clamped tightly, the labor intensity of the operator is reduced, and the working efficiency is improved; the locating groove is arranged in cooperation with polyethylene materials subjected to injection molding, so that the binding post does not disengage from the pipe easily, and locating is reliable.
Description
Technical field
The present invention relates to polyethylene fused pipe, particularly relate to polyethylene fused pipe core rod location separated type wiring terminal.
Background technique
Polyethylene fused pipe is to connect electro-fusion welding machine by wiring terminal, export constant voltage by electro-fusion welding machine and supply with the polyethylene fused pipe and the polyvinyl piping materials that have assembled, the resistive conductor that makes to be preset in pipe fitting produces heat, resistive conductor heats pipe fitting and tubing, the pipe fitting and the tubing molecular chain under certain pressure that reach molten state connect again, reach regulation rear tubular member weld interval and tubing and enter cooling stage, sub polyethylene subchain in the middle of cooling procedure in the middle of pipe fitting and tubing rearranges crystallization, to reach the object of pipe fitting and tubing welding.Existing wiring terminal comprises conductive pole and matrix, in conductive pole and matrix, have an axial threading hole, when assembling, resistive conductor is passed to axial threading hole, held again the matrix of pliers clamping wiring terminal by operator, it is out of shape slightly and clamps resistive conductor, finally the die cavity of putting into of wiring terminal is carried out to injection moulding as inserts, the shortcoming that this structure exists is: need operator to hold pliers pairs of posts and clamp, troublesome poeration, the labor intensity that has improved operator, has reduced manufacturing efficiency.
Summary of the invention
The object of the invention is the shortcoming existing in order to overcome prior art, provide a kind of simple to operate, reduce labor intensity of operating staff, the polyethylene fused pipe core rod of increasing work efficiency location separated type wiring terminal.
The technological scheme of polyethylene fused pipe core rod of the present invention location separated type wiring terminal is: the conductive pole and the matrix that comprise wiring terminal, it is characterized in that being shaped with connecting groove and locating slot on described matrix, in connecting groove, have threading hole, have location cotter way in the bottom of matrix, in the cotter way of location, locating stud being set, matches with the positioning hole in injection machine core rod in the bottom of locating stud.
The invention discloses a kind of polyethylene fused pipe core rod location separated type wiring terminal, when assembling, first the threading hole through connecting groove by resistive conductor, and the reserved certain length of the part of passing, rotate again wiring terminal, make through resistive conductor uniform winding partly on connecting groove, it is fixed, and reach conduction object, then the bottom of locating stud is inserted in the positioning hole of core rod, and match with the location cotter way of the matrix bottom of wiring terminal in locating stud top, the bottom surface of matrix contacts with core rod outer wall, now mould matched moulds, wiring terminal carries out injection moulding as inserts to polyethylene fused pipe, in the die sinking of molding and forming rear mold, core rod is extracted the inside of polyethylene fused pipe out, core rod drives the location cotter way of locating stud and matrix to be separated simultaneously, thereby ensure the outward appearance after whole product molding and forming.This programme polyethylene fused pipe core rod location separated type wiring terminal, adopt resistive conductor through connecting groove, be rotated winding, easy to operate, the pliers clamping matrix of holding that need not operator makes it to clamp with resistive conductor again, reduce labor intensity of operating staff, improve working efficiency, had locating slot, coordinated with the polythene material of injection moulding, make wiring terminal be difficult for deviating from from pipe fitting, location is reliable.
Polyethylene fused pipe core rod of the present invention location separated type wiring terminal, the top of described locating stud is frustoconic shape, there is chamfering bottom along circumference.Top frustoconic shape, is conducive to coordinate with the cotter way location, location of matrix bottom, and in the time loosing core, deviate from easily on top, and there is chamfering bottom along circumference, and the positioning hole that is conducive to core rod coordinates, and coordinates reliable, not easy to wear, distortion.Described connecting groove and locating slot are circular groove.
