Abstract
A connecting rod type core drawing mechanism of a one-outlet and four-cavity elbow pipe fitting die comprises an upper die plate and a lower die plate. A fixed die plate is installed at the lower portion of the upper die plate. A fixed die embedment block is installed at the lower portion of the fixed die plate. A die pin is installed on the lower die plate. A movable die plate is installed on the die pin. A movable die embedment block is installed on the movable die plate. Four die cavities are formed between the movable die embedment block and the fixed die embedment block and internally provided with injection molding elbow pipe fittings. Elbow cores and flat-head cores are arranged on the inner walls of the elbow pipe fittings. An outer slide block is arranged at the position, on one side of each flat-head core, of the movable die plate. The front end of each outer slide block is connected with the corresponding flat-head core. The two sides of each outer slide block are each connected with a connecting rod. A rotating shaft is arranged between the position, on one side of each elbow core, of the movable die plate and the movable die embedment block and provided with a rotating plate. The other ends of the connecting rods are connected with a rotating plate. Fixed blocks are arranged on the rotating plate and connected with the elbow cores. Core drawing oil cylinders are arranged at the positions, on one side of the outer slide blocks, of the outer wall of the movable die plate and drive the outer slide blocks to draw cores.
Description
Technical field
The present invention relates to a kind of one and go out four chamber bend pipe tools die connecting rod formula core-pulling mechanisms, belong to mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, such as plastic pipe etc., plastic pipe comprises straight-through pipe fitting, bend pipe tools, threeway four-way pipe fitting etc.Traditional moulds produces bend pipe tools, mostly adopts rotary core pulling mode, utilizes rack-and-pinion to coordinate and rotates, gear and tooth bar respectively need a power to drive, and such as this structure, for the production of the processing mold in mould four chamber, just needs installation 8 power, cause mould structure complicated, volume is large, and cost is high.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, providing a kind of connecting rod that adopts to loose core mode, two products can be driven to complete elbow simultaneously for power and flat mouth is loosed core, efficiency is high, cost is economized, having stable behavior, and loosing core reliable one goes out four chamber bend pipe tools die connecting rod formula core-pulling mechanisms.
The technical scheme that the present invention one goes out four chamber bend pipe tools die connecting rod formula core-pulling mechanisms is: comprise upper mould plate and lower bolster, under cope match-plate pattern, solid plate is installed, under solid plate, fixed die insert is installed, lower bolster is installed mould pin, mould pin installs moving platen, moving platen installs moving die insert, four die cavitys are set between moving die insert and fixed die insert, the bend pipe tools of injection mo(u)lding is had in four die cavitys, the inwall of bend pipe tools has elbow fuse and flat mouth fuse, the moving platen being positioned at flat mouth fuse side described in it is characterized in that arranges an outer slide, the front end of outer slide connects flat mouth fuse, the both sides of outer slide respectively connect a connecting rod, between the moving platen and moving die insert of elbow fuse side, a rotating shaft is being set, one piece of rotor plate is installed in rotating shaft, the other end connection of rotating plate of connecting rod, rotor plate installs fixed block, fixed block connecting bend fuse, the moving platen outer wall of described outer slide side installs oil cylinder of loosing core, oil cylinder of loosing core drives outer slide to loose core.
The invention discloses a kind of one and go out four chamber bend pipe tools die connecting rod formula core-pulling mechanisms, when loosing core, mould die sinking before this, then to loose core cylinder efficient, drive outer slide outward cunning is loosed core, outer slide directly drives flat mouth fuse to extract out from the flat mouth side of bend pipe tools, simultaneously, the connecting rod of outer slide both sides drives one piece of rotor plate to rotate around the shaft separately, the radian that rotor plate rotates designs at the very start, identical with the radian of elbow fuse, makes rotor plate drive fixed block on it, fixed block drives elbow fuse to rotate extraction from the inwall of bend pipe tools, has loosed core.Adopt the link-type core-pulling mechanism of this programme, the whole action of loosing core of two bend pipe tools (goes out two chambeies) is only driven by a power of loosing core (oil cylinder), but mould goes out four cavity configurations in the general employing one of design, namely a mould produces four products, and whole action of loosing core only needs two oil cylinders of loosing core, compared with existing 8 oil cylinders of loosing core, greatly save cost, and having stable behavior of synchronously loosing core, loose core more reliable, efficiency is higher.
Of the present invention one goes out four chamber bend pipe tools die connecting rod formula core-pulling mechanisms, described rotating shaft and be equipped with lower bearing and lower bearing between moving platen and moving die insert, makes axis of rotation more smooth and easy.Described rotor plate is shaped with brace, and connecting rod is connected on brace, easy to connect.Described moving platen arranges some wear-resistant blocks, and wear-resistant block is corresponding with rotor plate bottom surface, has had wear-resistant block, reduces the friction of moving platen and rotor plate, extends die life.
