Description

Inversed port of III-shaped tray forklift hole secondary core-pulling mechanism
Technical field
The present invention relates to a kind of inversed port of III-shaped tray forklift hole secondary core-pulling mechanism, belong to mould of plastics field, for the production of plastic pallet.
Background technology
Various medicine foods, machinery equipment, plastics chemical industry, raw material etc., in warehousing and logistics progress, are often used pallet.The kind of pallet is many, by shape, divides, and has III-shaped, matrix pattern and two-sided lattice type etc., III-shaped pallet, and the shape of its bottom panel is as river word, and forklift hole crosses bottom panel.The edge of prior art tray forklift hole is without falling mouth, in real work, if utilize carrying fork truck pallet, the fork of fork truck can easily inject without in the forklift hole falling mouthful, if but utilize go-cart transportation tray, because go-cart is Manual-pushing, forklift hole is not shaped with down mouth, the fork of go-cart is difficult to insert, so have people to design to be shaped with down the pallet of mouthful forklift hole.But forklift hole is shaped with down after mouth, and the core-pulling slide block of forklift hole has just had back-off, the demoulding of can not directly loosing core.
Summary of the invention
The object of the invention is in order to overcome the shortcoming of prior art, a kind of employing twice core pulling is provided, make back-off on slide block from forklift hole, fall mouthful to deviate from smoothly, overcome pallet product in storage and transportation, fork truck and go-cart can not both general difficult problems, make pallet adapt to the wide inversed port of III-shaped tray forklift hole secondary core-pulling mechanism of handbarrow scope.
The technical scheme of inversed port of III-shaped tray forklift hole secondary core-pulling mechanism of the present invention is: comprise compound plate and lower compound plate, described upper compound plate connects cavity plate through cushion block, mount type cavity insert in cavity plate, on described lower compound plate, mould pin is installed, mount type central layer on mould pin, core is installed in core plate to be inserted, core is inserted and cavity block forms die cavity, described lower compound plate connects, lower roof plate, thimble is installed on upper plate, thimble is inserted through core plate and core, ejection cylinder is installed on lower roof plate, the piston rod that ejects of ejection cylinder connects lower compound plate, in described lower compound plate, sprue bush is installed, sprue bush connecting passage frame, runner frame connects cast gate, cast gate is communicated with die cavity, planker is installed respectively in the both sides of described core plate, planker connects I-shaped piece, on I-shaped piece, slide block is installed, slide block stretches in die cavity, slide block is driven through the piston rod of loosing core by the oil cylinder of loosing core, it is characterized in that described slide block comprises top shoe and sliding block, in sliding block, be shaped with spring groove, mounting spring in spring groove, one of spring connects sliding block by first screw, the other end of spring connects top shoe by second screw, on sliding block, be shaped with stopper slot, mounting limit pin under top shoe, spacer pin matches with stopper slot.
Shaped tray forklift hole secondary core-pulling mechanism for inversed port of the present invention, during the demoulding, first by injection machine, drive upper compound plate, cushion block, cavity plate moves upward together with cavity block, mould die sinking, the oil cylinder of loosing core again drives the outwards motion on planker slowly simultaneously of sliding block and I-shaped piece, at this moment the spring in tight state originally, because lacked the squeezing action of sliding block, make top shoe along with the motion of sliding block downward landing slowly under the effect of spring, Deng spacer pin, from one end of stopper slot, slide into the other end, then drive top shoe outwards motion together, until complete, loose core.When installing because cast gate at mould pin here, so mould pin will be arranged on to plastics machine charging aperture here here, so after slipper block loose core finishes, ejection cylinder work, lower roof plate and lower compound plate are separated, because lower compound plate is fixed on plastics machine, so in fact exactly lower roof plate is moved up, recycling thimble ejects pallet product, has so just completed the demoulding.This programme adopts twice core pulling mode, slide block is divided into upper and lower slide block, first sliding block outwards slides, slowly landing downwards of top shoe when sliding block outwards slides, when sliding block slides into after certain distance, drive again upper slip to loose core together, back-off on top shoe from falling mouth, is deviate from forklift hole smoothly, its reasonable in design, stable action, reliable, particularly overcome pallet product in storage and transportation, the difficult problem that fork truck and go-cart can not be used simultaneously, makes pallet adapt to handbarrow scope wide.
Shaped tray forklift hole secondary core-pulling mechanism for inversed port of the present invention, is equipped with location guide in the spring described in it, has had location guide, plays fixing spring effect, also spring is play the guiding role simultaneously, makes upper and lower slide block separately easily.On sliding block described in it, gib block is installed, is shaped with chute in top shoe, chute matches with gib block, and top shoe is prolonging slowly landing downwards of gib block.
