Description
Technical field
The present invention relates to a kind of core-pulling mechanism of flared pipe fitting injection molding, belong to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic product, as plastic pipe, flared pipe fitting particularly at first needs during the demoulding enlarging place is loosed core after the demoulding, could the flared pipe fitting body be ejected outside the mould by the mould ejecting mechanism.Structure is taken off in traditional general employing of flared pipe fitting mould enlarging place by force, though take off simple in structurely by force, processing cost is low, and flared pipe fitting is pulled easily when loosing core, and causes product rejection.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of employing enlarging punishment to cut eight, the curved pin of dovetail structure and locked mode matches, big slide block compressing small slide block when loosing core and finish enlarging and loose core, and the demoulding is flared pipe fitting injection molding core-pulling mechanism smoothly.
The technical scheme of flared pipe fitting injection molding core-pulling mechanism of the present invention is: comprise mould top clamping plate and Bottom clamp plate, top clamping plate connects solid plate, the mould pin is installed on the Bottom clamp plate, ejector retainner plate and thimble compound plate are set in the mould pin, connect thimble on the ejector retainner plate, on the mould pin moving platen is installed, the flared pipe fitting that moulding is arranged between moving platen and the solid plate, it is characterized in that Bottom clamp plate one side erector block, on the I-shaped piece slide block is set, enlarging slide block octahedron is set in the slide block, the octahedral head of enlarging slide block 4 big slide blocks of enlarging arranged in a crossed manner and 4 enlarging small slide blocks, wherein the big slide block of enlarging contacts with the oblique dovetail groove of the octahedral head of enlarging slide block, the enlarging small slide block contacts with the octahedral header planes of enlarging slide block, the big slide block of enlarging and enlarging small slide block combination mutually cooperate with the enlarging of flared pipe fitting, in the enlarging slide block octahedron connecting rod is set, the head of connecting rod connects the slide block core, the slide block core matches with the inwall of flared pipe fitting, the afterbody of connecting rod connects the oil cylinder of loosing core, be shaped on oblique chute in the octahedral centre of enlarging slide block, the curved pin of connection locked mode under the solid plate, the curved pin of locked mode matches with oblique chute.
Flared pipe fitting injection molding core-pulling mechanism of the present invention, when loosing core, at first drive moving platen and solid plate die sinking by injection machine power, during die sinking, because the curved pin of the locked mode under the solid plate cooperates with the octahedral oblique chute of enlarging slide block, drive the octahedra outwards slip of enlarging slide block, because the big slide block of enlarging is that oblique dovetail groove contacts with the octahedral head of enlarging slide block, the outer sliding big slide block of enlarging that is equivalent to of enlarging slide block octahedron is along tiltedly dovetail groove downslide (radial contraction), and the big slide block of enlarging is when gliding, the setting because the big slide block of enlarging and enlarging small slide block cross one another, thereby compressing enlarging small slide block glides simultaneously (contraction), make the big slide block of enlarging and enlarging small slide block from the enlarging demoulding of flared pipe fitting, this moment, the mould die sinking finished, the enlarging place demoulding of flared pipe fitting is finished, but the slide block core is still in the inwall of flared pipe fitting, so by the oil cylinder drivening rod of loosing core the slide block core is loosed core from the inwall of flared pipe fitting again, so far, flared pipe fitting is loosed core and is finished, by ejecting mechanism flared pipe fitting is ejected outside the mould at last, the demoulding is finished.The curved pin of the locked mode of this programme has possessed locked mode (pinning slide block during matched moulds) simultaneously and has loosed core (the octahedra slip of enlarging slide block loosed core) effect, reduce power, save cost, the big slide block of enlarging contacts with the octahedra dovetail groove of enlarging slide block, slide balance is good, and the demoulding is smooth.
Flared pipe fitting injection molding core-pulling mechanism of the present invention, the circle cover is installed in the described slide block, installing connecting rods fixed block in the circle cover, the afterbody of connecting rod is fixed in the connecting rod fixed block, and the connecting rod fixed block connects the oil cylinder of loosing core, and the connecting rod fixed block has been arranged, connecting rod is installed reliable, it is convenient to connect the oil cylinder of loosing core, and between connecting rod fixed block and the enlarging slide block octahedron stopper slot is arranged, and prevents that enlarging slide block octahedron from skidding off.Be equipped with the opening folder in the described connecting rod fixed block, be equipped with spacer pin in the enlarging slide block octahedron, spacer pin matches with the opening folder, to the octahedra position-limiting action that rises of enlarging slide block.Described I-shaped piece outer end wall is installed tank plate, and the oil cylinder of loosing core is installed on the tank plate, and the oil cylinder of loosing core is easy for installation, firm.
