Description
Technical field
The present invention relates to a kind of fork interlock elevating mechanism that is applied to die cylinder underneath type plastic injecting and blowing blow moulding machine, belong to the plastics machinery field.
Background technology
At present; Common one-step method plastic injecting and blowing blow moulding machine mainly is made up of injection device, up-down turn device, blowing device, stripper apparatus, hydraulic system, air-channel system, electric-control system and microcomputer automatic control system etc.; Lifting action is fully independently with respect to folding mould action, and hoist cylinder is positioned at same axis with main shaft and is in the main shaft bottom and directly be connected, and causes the plug injury accident for protecting the mould plug when capstan head is made lifting action, not run into upper mould; Have to after the mould die sinking puts in place, do again the capstan head vertical motion; And after capstan head decline puts in place, do mould assembling action again, and just to accomplish an idle loop and must walk 5 steps, i.e. die sinking, capstan head rise, transposition is advanced, capstan head descends and matched moulds; Cycle period is long, and production efficiency is low.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art; A kind of employing fork link gear is provided, in an idle loop, 5 original steps is shortened to 3 steps; Circulation time significantly shortens, the underneath type plastic hollow make-up machine fork interlock elevating mechanism of enhancing productivity.
The technical scheme of underneath type plastic hollow make-up machine fork interlock elevating mechanism of the present invention is: comprise the workbench that is installed on the support, bed die and mold are installed on the workbench, install crossbeam on the mold; Bed die connects down sill, and sill connects the folding mould oil cylinder down, in a side of upper and lower mould capstan head is set; Plug is installed on the capstan head, and plug matches with upper and lower mould, and main shaft is installed in the capstan head; Main shaft is driven by elevating mechanism, and workbench connects the transposition casing down, it is characterized in that described elevating mechanism comprises that the main shaft lower end connects fork; One of fork is shaped on first fulcrum; The other end of fork is shaped on second fulcrum, and first fulcrum connects sill through coupling assembling, and second fulcrum connects the fulcrum oil cylinder that is in contraction state through second joint; Be shaped on the 3rd fulcrum on the fulcrum oil cylinder, the 3rd fulcrum connects the transposition casing through cylinder pedestal.
Underneath type plastic hollow make-up machine fork interlock elevating mechanism of the present invention, during work, the piston rod of fulcrum oil cylinder is in contraction state all the time; Same-action is equal to a connecting rod, and fork first fulcrum connects sill, during die sinking; The folding mould oil cylinder drives sill and rises, and drives first fulcrum simultaneously and rises, and drives main shaft then and is installed in the capstan head rising on the main shaft; Thereby having realized that die sinking and capstan head rise carries out synchronously, and in like manner sill descends during mould assembling action, drives first fulcrum and descends; Then the capstan head that drives main shaft and be installed on the main shaft descends, thereby having realized that matched moulds descends with capstan head carries out synchronously, i.e. capstan head and the folding mould up-down (folding) that links.When main shaft rose, second fulcrum was only done slight swing, guaranteed that the main shaft lower end is positioned near the position, center of fork all the time, and main shaft rises steadily.But when machine debugging (manual state); Then sill remains static, and just the position of first fulcrum is fixed, and this moment, the piston rod of fulcrum oil cylinder was made expanding-contracting action; Just can realize that second position of the fulcrum rotates around first fulcrum; Be that fork rotates around first fulcrum, and drive main shaft and the capstan head that is installed on the main shaft is done elevating movement, realize the capstan head hand-operated lifting.This programme adopts the fork interlock to go up and down, and compared with present technology, action is simple, in the idle loop 5 original steps is shortened to 3 steps, and circulation time significantly shortens, and enhances productivity.
Underneath type plastic hollow make-up machine fork interlock elevating mechanism of the present invention; The center of said fork is shaped on the bearing loose slot, and the lower end of main shaft is equipped with bearing and bearing block, and the both sides of bearing block are equipped with ball bearing; Ball bearing matches with the bearing loose slot; Make main shaft lower end (bottom) be positioned near the position of fork mid point all the time, thereby make the speed of capstan head lifting action and stroke be about the half the of folding mould action all the time, upper mould can not run into the plug that is installed on the capstan head when so just having guaranteed the folding mould; Mechanism is safe and reliable, meets the requirement of annotating blow moulding fully.Described coupling assembling comprises first joint that connects first fulcrum, and first joint connects screw mandrel, and screw mandrel has screw rodb base, and screw rodb base connects sill, and is easy to connect, firm.
