Description

Plastic chair mould chair foot sticks up rod-type core-pulling lock mold mechanism
Technical field
The present invention relates to a kind of plastic chair mould chair foot and stick up rod-type core-pulling lock mold mechanism, belong to injection mold field.
Background technology
Injection mold is used to produce plastic, such as plastic chair etc..The kind of plastic chair has a lot, and concrete structure is the most different.Produce a kind of have in the plastic chair of empty chair foot and Rattan-shaped seat support time, the chair foot demoulding of hollow needs to loose core, and the Rattan-shaped seat support demoulding is also required to loose core, and chair foot is loosed core and usually completed before mould die sinking, stable to guarantee to loose core.But in actual production, owing to the volume of plastic chair mould is relatively big, injection pressure is big, and the oil cylinder of loosing core of middle empty chair foot bears the biggest pressure, is susceptible to the mould situation that rises, so needing to arrange clamping mechanism on chair foot core-pulling mechanism, to prevent the mould that rises.Chair foot has 4; it is divided into two and lower two when injection; the clamping mechanism connecting root chair foot in traditional moulds uses cover half side chain mould mode mostly; lock module is i.e. installed in the cover half side of mould; lock module keeps off outside core-pulling slide block, reaches to prevent core-pulling slide block from occurring that the phenomenon retreating the mould that rises occurs because of injection pressure big two.And the separation of lock module relies on mould die sinking power and completes.Lower two chair foot locked modes generally use slide block structure, and structure is complicated.
Summary of the invention
The invention aims to overcome the shortcoming of prior art; one is provided to use twice-die-opening and stick up bar structure and combine; utilizing spring force to press down, the plastic chair mould chair foot making lock module loose core in the case of the seat support insert not die sinking of mould sticks up rod-type core-pulling lock mold mechanism.
nullThe technical scheme that plastic chair mould chair foot of the present invention sticks up rod-type core-pulling lock mold mechanism is: include that mould moving platen and cover half are pulled，Gate plate is installed on solid plate，Moving platen is installed seat support chair back insert，Seat support chair foot insert is set on moving platen and seat support chair back insert，Solid plate is installed backrest insert，Backrest insert matches with seat support chair back insert and constitutes chair back die cavity，The injection mo(u)lding chair back in chair back die cavity，Seat support chair back insert matches with seat support chair foot insert and constitutes seat support die cavity，Injection mo(u)lding seat support in seat support die cavity，The end face of seat support chair foot insert and bottom surface are pulled with cover half respectively and moving platen matches constitutes upper chair foot die cavity and lower chair foot die cavity，Empty chair foot and lower middle empty chair foot in distinguishing in injection mo(u)lding in upper chair foot die cavity and lower chair foot die cavity，In upper, empty chair foot and lower middle empty chair foot are respectively arranged with core-pulling lock mold mechanism，It is characterized in that the core-pulling lock mold mechanism of described upper middle empty chair foot includes being positioned at the upper core_pulling pole of middle empty chair foot，The outer end of upper core_pulling pole connects upper core-pulling slide block，Upper core-pulling slide block is arranged on looses core in support，On support of loosing core be arranged on seat support chair foot insert outer wall top，Upper core-pulling slide block loosed core from above oil cylinder through oil cylinder rod connect drive loose core，Locked mode projection is set on upper core-pulling slide block，Described solid plate arranges locked mode through groove，Locked mode through groove arranges bearing pin，On bearing pin, activity arranges locked mode bar，One of locked mode bar is matched with locked mode projection，Described moving platen outer wall installs push rod，Push rod withstands on below the other end of locked mode bar，Described gate plate arranges compression spring，Through depression bar in compression spring，Depression bar inserts in the other end of locked mode bar，And compression spring is pressed in above the other end of locked mode bar；The core-pulling lock mold mechanism of described lower middle empty chair foot includes the lower core_pulling pole being positioned in lower middle empty chair foot; the outer end of lower core_pulling pole connects lower core-pulling slide block; lower core-pulling slide block is arranged on down looses core in support; under support of loosing core be arranged on seat support chair foot insert outer wall bottom; lower core-pulling slide block loosed core by down oil cylinder through lower cylinder rod connect drive loose core; lower locked mode projection is set on lower core-pulling slide block; moving platen arranges lower locked mode groove; lower locked mode projection and lower locked mode fit depressions; described seat support chair foot insert sidewall installs die sinking oil cylinder, and die sinking oil cylinder connects solid plate.
The invention discloses a kind of plastic chair mould chair foot and stick up rod-type core-pulling lock mold mechanism; during injection; due to upper locked mode projection and locked mode bar and lower locked mode projection and the locked mode effect of lower locked mode groove; core-pulling slide block and lower core-pulling slide block is made to stand fast under injection pressure; effectively prevent mould from rising mould, it is ensured that injection quality.During the demoulding, the most upper and lower chair foot is loosed core, then the seat support slip demoulding, the last chair back, seat support and chair foot ejection device.This programme be mainly characterized by the case of seat support chair foot insert not die sinking, it is achieved upper core_pulling pole and lower core_pulling pole unlock looses core.First, moving platen and seat support chair back insert and solid plate die sinking is driven by injection machine power, owing to seat support chair foot insert sidewall installs die sinking oil cylinder, die sinking oil cylinder connects solid plate, therefore, seat support chair foot insert is motionless, makes the lower locked mode projection being arranged on the lower core-pulling slide block in seat support chair foot insert depart from the lower locked mode groove on moving platen, it is achieved lower core_pulling pole is loosed core.Meanwhile, driving push rod to move during moving platen die sinking, push rod departs from locked mode bar, and one of locked mode bar, under the effect of compression spring and depression bar, tilts around bearing pin, makes the other end of locked mode bar depart from upper locked mode projection, it is achieved upper core_pulling pole is loosed core.Then, die sinking cylinder efficient, drive seat support chair foot insert and solid plate die sinking, by the ejecting mechanism of mould by outside the product ejection die of molding, complete product stripping.This programme uses twice-die-opening dexterously and sticks up the rod-type demoulding and combine, it is achieved upper core_pulling pole and lower core_pulling pole core_pulling demoulding simultaneously, reaches mould upper and lower chair foot in the case of not die sinking and completes the purpose loosed core, both the mould that rises had been prevented, ensureing product injection quality, the demoulding is smooth again, and production efficiency is high.
