Description
Technical field
The present invention relates to a kind of inversed port of III-shaped tray forklift hole secondary core-pulling mechanism, belong to the mould of plastics field, be used to produce plastic pallet.
Background technology
Various medicine foods, machinery equipment, plastics chemical industry, raw material etc. often use pallet in warehousing and logistics progress.The kind of pallet is many, by the shape branch, III-shaped, matrix pattern and two-sided grid type etc. is arranged, III-shaped pallet, and the shape of its bottom panel is as the river word, and forklift hole crosses bottom panel.The edge of prior art tray forklift hole does not have down mouth, in real work, if utilize the fork truck transportation tray, the fork of fork truck can inject in the forklift hole that does not have mouth easily, if but utilize the go-cart transportation tray, because being manpower, go-cart promotes, forklift hole is not shaped on down mouth, the fork of go-cart is difficult to insert, so have the people to design to be shaped on down the pallet of mouthful forklift hole.After but forklift hole was shaped on down mouth, the slide block of loosing core of forklift hole had just had back-off, the demoulding of can not directly loosing core.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of employing secondary to loose core, make the back-off on the slide block fall mouthful to deviate from from forklift hole smoothly, overcome the 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 following compound plate, the described compound plate of going up connects cavity plate through cushion block, mount type cavity insert in the cavity plate, on the described compound plate down the mould pin is installed, mount type central layer on the mould pin, core is installed in the core plate to be inserted, core is inserted and cavity block constitutes die cavity, in the connection of described compound plate down, lower roof plate, thimble is installed on the upper plate, thimble passes core plate and core is inserted, on lower roof plate, install and eject oil cylinder, the piston rod that ejects that ejects oil cylinder connects compound plate down, in the compound plate sprue bush is installed under described, sprue bush connects the runner frame, the runner frame connects cast gate, cast gate is communicated with die cavity, the both sides of described core plate are installed planker respectively, planker connects the I-shaped piece, on the I-shaped piece slide block is installed, slide block stretches in the die cavity, slide block is driven through the piston rod of loosing core by the oil cylinder of loosing core, and it is characterized in that described slide block comprises top shoe and sliding block, is shaped on spring groove in the sliding block, mounting spring in the spring groove, one of spring connects sliding block by the first screw, and the other end of spring connects top shoe by the second screw, is shaped on stopper slot on sliding block, top shoe is installed spacer pin down, and spacer pin matches with stopper slot.
Shaped tray forklift hole secondary core-pulling mechanism for inversed port of the present invention, during the demoulding, at first drive and go up compound plate by injection machine, cushion block, cavity plate and cavity block move upward together, the mould die sinking, the oil cylinder of loosing core again drives sliding block and the outwards motion on planker slowly simultaneously of I-shaped piece, at this moment originally be in the spring of tight state, because lacked the squeezing action of sliding block, make top shoe along with the motion of sliding block slowly downward landing under the effect of spring, slide into the other end Deng spacer pin from an end of stopper slot, drive top shoe outwards motion together then, loose core up to finishing.Because when installing because cast gate at the mould pin here, so will be installed in the plastics machine inlet capable to the mould pin here here, so after slide block is loosed core end, eject oil cylinder work, lower roof plate and following compound plate are separated, because compound plate is fixed on the plastics machine down, so in fact exactly lower roof plate is moved up, utilize thimble that the pallet product is ejected again, so just finished the demoulding.This programme adopts the secondary mode of loosing core, slide block is divided into upper and lower slide block, at first sliding block outwards slides, slowly landing downwards of top shoe when sliding block outwards slides, after sliding block slides into certain distance, driving upward slip again looses core together, back-off on the top shoe from falling mouth, is deviate from forklift hole smoothly, its reasonable in design, stable action, reliable, particularly overcome the pallet product in storage and transportation, the difficult problem that fork truck and go-cart can not be used simultaneously, it is wide to make pallet adapt to the handbarrow scope.
Shaped tray forklift hole secondary core-pulling mechanism for inversed port of the present invention is equipped with location guide in its described spring, and location guide has been arranged, and plays the fixing spring effect, also spring is play the guiding role simultaneously, makes upper and lower slide block separately easily.On its described sliding block gib block is installed, is shaped on chute in the top shoe, chute matches with gib block, and top shoe is prolonging slowly landing downwards of gib block.
