Description

The fast interface pipe fitting mold strong release mechanism of loosing core

Technical field

The utility model relates to a kind of fast interface pipe fitting mold strong release mechanism of loosing core, and belongs to mould of plastics field.

Background technology

In pipe laying process, sometimes need on a long tube, connect an other three-way pipeline, often adopt fast interface (or the quick coupling of expressing one's gratification) to connect, the main structure of fast interface comprises that an arc that is slightly larger than semicircle connects expansion plate, is shaped with three-limb tube (comprising straight tee (ST.TEE) and skew T) on arc connection expansion plate.Produce at present fast interface and generally adopt mould of plastics processing, before the demoulding of fast interface body, need to connect expansion plate to arc and be connected and loose core with three-limb tube.Prior art arc connection expansion plate employing two crashes and looses core, and needs two power of loosing core, and cost investment is large, and producing cost is high.Three-limb tube is loosed core and is adopted Angle Pin translation to loose core, although be to utilize the translation of mould die sinking power to loose core, without external power, cost is economized, mould inside complex structure, and action is unstable, and affects the clamp force of mould, causes product percent defective high.

Summary of the invention

The purpose of this utility model is the shortcoming in order to overcome prior art, provides a kind of arc to connect and expands one-sided strong the taking off of plate employing, and three-limb tube adopts loose core of oil cylinder, simple in structure, having stable behavior can ensure again product quality, the fast interface pipe fitting mold that production efficiency the is high strong release mechanism of loosing core simultaneously.

The loose core technical scheme of strong release mechanism of the utility model fast interface pipe fitting mold is: comprise compound plate and lower compound plate on mould, under upper compound plate, solid plate is installed, fixed die insert is installed in solid plate, two mould pin are installed on lower compound plate, on two mould pin, moving clamping plate is installed, moving platen is installed on moving clamping plate, moving die insert is installed in moving platen, between moving die insert and fixed die insert, die cavity is set, in die cavity, arrange arc connect expand plate insert and three-limb tube insert, arc connect expand that plate is inserted and three-limb tube is inserted and die cavity between gap have the quickening interface of injection mo(u)lding, arc connect expand plate insert is connected with the arc of accelerating interface expansion plate match, three-limb tube is inserted and is matched with the three-limb tube of accelerating interface, between two mould pin, upper plate and lower roof plate are set, thimble is installed on upper plate, thimble contacts with quickening interface through moving clamping plate and moving die insert, described in it is characterized in that, being positioned at arc connects on the moving platen that expands plate outside chute is set, strong de-outer slide is slidably installed on chute, strong de-outer slide connects arc connection expansion plate and inserts, and driven outer sliding by strong de-oiling cylinder, on the moving platen in three-limb tube outside, install and fixedly insert, the upper installation double sided slider bar of fixedly inserting, on double sided slider bar, arrange to loose core and insert, the connecting tee tube connector of inserting of loosing core is inserted, and drive and loose core in the upper outside cunning of double sided slider bar by the oil cylinder of loosing core.

The fast interface pipe fitting mold of the present utility model strong release mechanism of loosing core, when the demoulding, mould die sinking, first moved downwards by the dynamic model part of injection machine power driven mold, the cover half partial fixing of mould is on injection moulding machine template, moving die insert separates with fixed die insert, then strong de-oiling cylinder drives strong de-outer slide to slide to moving platen outside on chute, strong de-outer slide drives arc connection expansion plate to insert and forces to connect to expand plate from arc to pull out, now, arc connects expansion plate and has distortion slightly, but the ductility of utilizing plastic material itself to have, can automatically restore, can there is not impact to the quality of product.When arc connection expansion plate is de-by force, the oil cylinder of loosing core drives loosing core the outwards slip on double sided slider bar of inserting, loosing core inserts drives three-limb tube to insert and extract out from three-limb tube, finally by injection machine powered lower roof plate and upper plate, upper plate drives thimble by outside fast interface ejection die, and the demoulding completes.Compared with the prior art, structure is simpler, and the action of loosing core is more stable, and product quality is better, and production efficiency is higher.

The fast interface pipe fitting mold of the present utility model strong release mechanism of loosing core, described solid plate one side is installed lock module, looses core on inserting and is shaped with locked mode groove, and lock module matches with locked mode groove, and locked mode is firm, guarantee product quality.
