Description
Technical field
The utility model relates to a kind of circular arc pipe fitting die connecting rod formula arc bend core-pulling mechanism, belongs to injection mold field.
Background technology
Adopt injection mold to produce plastic pipe, such as circular arc (curved) pipe fitting etc., because circular arc pipe fitting is curved shape, cannot loose core and eject by straight line when product stripping.Therefore, someone devises a kind of rack-and-pinion rotary core pulling structure, and the main feature of this structure is that oil cylinder drives linear gear rack, linear gear rack and gears meshing, gear is fixed in cavity block, drives cavity block to rotate, and cavity block drives pipe fitting to rotate extraction around fuse.When loosing core, because whole die cavity all will rotate, mould inside structural wear is very large, and maintenance cost is high.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, there is provided a kind of and adopt connecting rod connected mode, oil cylinder linear drives, linkage block circular arc rotarily drives fuse and looses core, without the need to the whole rotation of die cavity, wear and tear little, the circular arc pipe fitting die connecting rod formula arc bend core-pulling mechanism that processing, maintenance cost economize.
The technical scheme of the utility model circular arc pipe fitting die connecting rod formula arc bend core-pulling mechanism is: comprise stationary mould for mould seat board and Bottom clamp plate, under top clamping plate, solid plate is installed, Bottom clamp plate installs two pieces of mould pin, two mould pin install moving platen, die cavity is shaped with between moving platen and solid plate, the circular arc pipe fitting of injection mo(u)lding is had in die cavity, circular arc pipe fitting inner wall has circular arc fuse, ejector retainner plate and lower ejector retainner plate are set between two pieces of described mould pin, connecting ejector pin on upper ejector retainner plate, thimble contacts with circular arc pipe fitting bottom surface through moving platen, it is characterized in that arranging arc chute in described moving platen, circular arc linkage block is set in arc chute, the head of circular arc linkage block connects circular arc fuse, the afterbody of circular arc linkage block connects connecting rod through pivot pin, connecting rod distribution is flexibly connected linear slider, linear slider to be loosed core action by oil cylinder band action straight line.
Circular arc pipe fitting die connecting rod formula arc bend core-pulling mechanism of the present utility model, primary structure arranges arc chute in described moving platen, circular arc linkage block is set in arc chute, the head of circular arc linkage block connects circular arc fuse, the afterbody of circular arc linkage block connects connecting rod through pivot pin, connecting rod distribution is flexibly connected linear slider, and linear slider to be loosed core action by oil cylinder band action straight line.This programme adopts oil cylinder linear drives, and connecting rod connects, linkage block Circular Sliding, and drive circular arc fuse rotary core pulling, structure is simple, having stable behavior, reliable, and handling ease, cost is economized, easy to maintenance.
Circular arc pipe fitting die connecting rod formula arc bend core-pulling mechanism of the present utility model, be provided with straight line in described moving platen and loose core groove, linear slider is arranged at straight line and looses core in groove.Had straight line to loose core groove, linear slider is arranged conveniently, looses core steadily.
