Abstract

The utility model provides a long-distance core-pulling structure of a circular tube shaped die, which enables a slide insert not to be interfered with an ejector pin, so that the operation life of the die is long. The long-distance core-pulling structure comprises a front die, a rear die, a front die core, a rear die core and a slide insert, a hollow cavity enclosed by the front die core and the rear die core is a cavity, and one end of the slide insert is positioned in the cavity. The long-distance core-pulling structure is characterized by further comprising a movable insert and a movable insert supporting ejector pin, the movable insert is positioned in a movable insert mounting slot enclosed by the front die core and the rear die core, the movable insert mounting slot is positioned below one side of the cavity, the slide insert penetrates through two side ends of the movable insert, the other end of the slide insert is clamped in a vertical linear guide rail slot of a cylinder core-pulling slide, one side of the cylinder core-pulling slide far away from the cavity is externally connected with a horizontally-moving cylinder, the bottom of the movable insert is supported on the movable insert supporting ejector pin, and the bottom of the movable insert supporting ejector pin is fixedly and tightly connected with a combination of an ejector retainer plate and an ejector plate.

Description

A kind of length of pipe shape mould is apart from loosing core structure

Technical field

The utility model relates to the mould structure technical field, is specially the long apart from loosing core structure of a kind of pipe shape mould.

Background technology

The length of existing pipe shape mould is apart from loosing core structure, and its row position mold insert and thimble often interfere and mold damage, makes that the life-span of mould is short.

Summary of the invention

The utility model provides the long apart from loosing core structure of a kind of pipe shape mould, and it makes row position mold insert and thimble can not interfere, and makes life span of mold long.

A kind of length of pipe shape mould is apart from loosing core structure; It comprises front mould, back mould, preceding die, back die, row position mold insert; The cavity that die, back die are surrounded before said is a die cavity; Said row position mold insert one end is positioned at said die cavity, it is characterized in that: it also comprises movable insert, movable insert supporting thimble, said movable insert be positioned at said before the movable insert mounting groove that surrounded of die, back die; Said movable insert mounting groove is positioned at a side-lower of said die cavity; Said row position mold insert runs through the two side ends of said movable insert, the other end of said row position mold insert be installed in the capable position of loose core of oil cylinder vertically in the line slideway groove, the capable position of said loose core of oil cylinder away from the external oil cylinder that moves horizontally of cavity side; The bottom supporting of said movable insert is in said movable insert supporting thimble, and the bottom of said movable insert supporting thimble is fastenedly connected the combination of face needle plate, end needle plate.

It is further characterized in that: the cross section of said movable insert mounting groove is a convex; The bottom of said movable insert is a boss structure; The boss structure of said movable insert is loaded on the bottom of said movable insert mounting groove, and the height of the boss structure of said movable insert is less than the height of the bottom cell body of said movable insert mounting groove;

Between the top of said movable insert bottom, movable insert supporting thimble support spring is installed.

After adopting the structure of the utility model, during die sinking, front mould, preceding die rise; Afterwards, the combination of face needle plate, end needle plate rises, and drives movable insert supporting thimble and rises; Movable insert supporting thimble promotes movable insert and rises, and movable insert drives row position mold insert, product rises, and separates thereby make product accomplish with the back model cavity; The capable position of loose core of oil cylinder on the mould begins to carry out the level motion of loosing core, and product is barred from movable insert near die cavity one side, and a row position mold insert is separated with product; Product freely falls, and row position mold insert and thimble can not interfere in the whole process, make life span of mold long.
