Description
Technical field
The present invention relates to a kind of plastic chair mould chair leg sticks up rod-type core pulling clamping mechanism, belong to injection mold field.
Background technology
Plastic, such as plastic chair etc. are produced using injection mold.The species of plastic chair has a lot, specific construction
Different.When producing a kind of plastic chair with hollow chair leg and Rattan-shaped seat support, the chair leg demoulding of hollow needs core pulling,
The Rattan-shaped seat support demoulding is also required to core pulling, and chair leg core pulling is usually to complete before mould die sinking, stable to guarantee core pulling.But
In actual production, because the volume of plastic chair mould is larger, injection pressure is big, and the core pulling oil cylinder of hollow chair leg bears very big pressure
Power, is susceptible to the mould situation that rises, so needing to arrange clamping mechanism on chair leg core-pulling mechanism, to prevent the mould that rises.Chair leg has 4
Root, is divided into two and lower two in injection, and the clamping mechanism that traditional moulds connect root chair leg adopts cover half side chain mould mostly
Mode, installs lock module in the cover half side of mould, and lock module keeps off outside core-pulling slide block, reaches and prevents core-pulling slide block because of injection
The phenomenon that the mould that rises occurs retreating in pressure big two occurs.And the separation of lock module relies on mould die sinking power to complete.Lower two
Root chair leg locked mode generally adopts slide block structure, complex structure.
Content of the invention
The invention aims to overcoming the shortcoming of prior art, one kind is provided using twice-die-opening and to stick up bar structure phase
In conjunction with automatically being pushed using spring force, make the plastic chair of lock module core pulling in the case that the seat support insert of mould does not mold
Mould chair leg sticks up rod-type core pulling clamping mechanism.
The technical scheme that plastic chair mould chair leg of the present invention sticks up rod-type core pulling clamping mechanism is：Including mould moving platen with calmly
Template, solid plate installs gate plate, installs seat support chair back insert in moving platen, and moving platen and seat support chair back insert arrange chair
Seat foot insert, installs backrest insert in solid plate, backrest insert is matched with seat support chair back insert and constitutes chair back die cavity, the chair back
The injection mo(u)lding chair back in die cavity, seat support chair back insert is matched with seat support chair leg insert and constitutes seat support die cavity, notes in seat support die cavity
Molded seat support, the top surface of seat support chair leg insert and bottom surface match with solid plate and moving platen respectively the upper chair leg die cavity of composition and
Hollow chair leg and lower hollow chair leg in difference injection mo(u)lding in lower chair leg die cavity, upper chair leg die cavity and lower chair leg die cavity, upper hollow
Chair leg and lower hollow chair leg respectively has core pulling clamping mechanism it is characterised in that the core pulling clamping mechanism of described upper hollow chair leg includes
Upper core_pulling pole in upper hollow chair leg, the outer end of upper core_pulling pole connects upper core-pulling slide block, and upper core-pulling slide block is arranged on to be taken out
In core support, upper core pulling support is arranged on seat support chair leg insert outer wall top, and upper core-pulling slide block is by upper core pulling oil cylinder through upper cylinder
Bar connects drive core pulling, and upper core-pulling slide block arranges locked mode projection, arranges locked mode through groove, locked mode through groove in described solid plate
Middle setting bearing pin, activity setting locked mode bar on bearing pin, one of locked mode bar is matched with locked mode projection, described moving platen outer wall
Push rod is installed, push rod withstands on below the other end of locked mode bar, in described gate plate, compression spring is set, passes through in compression spring
Depression bar, 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；Described lower middle empty chair
The core pulling clamping mechanism of foot includes the lower core_pulling pole in lower hollow chair leg, and the outer end of lower core_pulling pole connects lower core-pulling slide block,
Lower core-pulling slide block is arranged in lower core pulling support, and lower core pulling support is arranged on seat support chair leg insert outer wall bottom, lower core-pulling slide block
Connected through lower cylinder rod by lower core pulling oil cylinder and drive core pulling, lower core-pulling slide block arranges lower locked mode projection, under arranging in moving platen
Locked mode groove, lower locked mode projection and lower locked mode fit depressions, described seat support chair leg insert side wall installs die sinking oil cylinder, die sinking
Oil cylinder connects solid plate.
The invention discloses a kind of plastic chair mould chair leg sticks up rod-type core pulling clamping mechanism, during injection, because upper locked mode is convex
Block and locked mode bar and the locked mode effect of lower locked mode projection and lower locked mode groove, make core-pulling slide block and lower core-pulling slide block in injection pressure
Standing fast under power, effectively preventing mould from rising by mould it is ensured that being molded quality.During the demoulding, upper and lower chair leg core pulling before this, then seat support cunning
The dynamic demoulding, the last chair back, seat support and chair leg ejection device.The feelings being mainly characterized by not molding in seat support chair leg insert of this programme
Under condition, core_pulling pole and the unblock core pulling of lower core_pulling pole in realization.First, moving platen and seat support chair back insert are driven by injection machine power
With solid plate die sinking, because die sinking oil cylinder installed by seat support chair leg insert side wall, die sinking oil cylinder connects solid plate, therefore, seat support chair
Foot insert is motionless, the lower locked mode on the lower locked mode projection on lower core-pulling slide block making to be arranged in seat support chair leg insert and moving platen
Groove departs from, and realizes lower core_pulling pole core pulling.Meanwhile, push rod is driven to move during moving platen die sinking, push rod is departed from locked mode bar, locked mode
One of bar, in the presence of compression spring and depression bar, tilts around bearing pin, so that the other end of locked mode bar and upper locked mode projection is taken off
From core_pulling pole core pulling in realization.Then, mold cylinder efficient, drive seat support chair leg insert to mold with solid plate, by the top of mould
Go out mechanism by outside the product ejection die of molding, complete product stripping.This programme is dexterously taken off with sticking up rod-type using twice-die-opening
Mould combines, and in realization, core_pulling pole and lower core_pulling pole core_pulling demoulding simultaneously, reach mould upper and lower chair leg in the case of not molding
Complete the purpose of core pulling, both prevented from rising by mould it is ensured that product is molded quality, and the demoulding is smoothly, production efficiency is high.
