Description
Technical field
The present invention relates to the rotary loose-core injection mould of a kind of ripple big syphon part, belong to mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic products, such as plastic pipe, particularly a kind of ripple big syphon part, the outer wall of this pipe fitting is bellows, and entire body is 135 ° of elbow shapes, is mainly used in blow-off line.Prior art produces such pipe fitting, because the radian of pipe fitting is larger, inner core pulling mostly adopts to crash and swings splicing pulled core structure, is divided into inwall fuse and two sections, enlarging fuse by fuse, and two sections of fuses are spliced by insert and form, adopt twice core pulling structure, twice core pulling just extracts fuse out after swinging, and internal structure is very complicated, and fuse often crashes, easy damage, inconvenient maintenance.And to loose core for twice be all that oil cylinder direct takes out mode, core pulling distance is long, and core-pulling mechanism stretches out outside mold, increases mould volume, makes mould only be suitable for large size plastic jetting-moulding device and could process, increase equipment investment.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, there is provided a kind of and adopt rotational structure, first time looses core for sidewall guiding is loosed core, second time is loosed core for rack-and-pinion rotary core pulling, fuse does not crash, having stable behavior of loosing core, reasonable in design, reduce mould volume, the rotary loose-core injection mould of ripple big syphon part reduced costs.
The technical scheme of the rotary loose-core injection mould of ripple big syphon part of the present invention is: comprise compound plate and lower compound plate on mould, under upper compound plate, solid plate is installed, in solid plate, fixed die insert is installed, lower compound plate installs mould pin, mould pin installs moving clamping plate, moving clamping plate installs moving platen, in moving platen, moving die insert is installed, the ripple big syphon part of injection mo(u)lding is had between moving die insert and fixed die insert, the inwall of ripple big syphon part has elbow fuse and enlarging fuse, be connected through gangbar between elbow fuse with enlarging fuse, described enlarging fuse is spliced to form by insert, under it is characterized in that described moving platen, swivel plate is set, swivel plate connects moving clamping plate through rotating shaft, swivel plate is arranged enlarging fuse to loose core block, enlarging fuse is loosed core block connection enlarging fuse, enlarging fuse is loosed core in block and is installed the axis of rolling, be positioned at enlarging fuse loose core block both sides solid plate outer wall install guide plate, guide plate arranges gathering sill of loosing core, described gathering sill of loosing core comprises straight guide groove and lower inclined guide groove, the two ends of the axis of rolling are stretched out enlarging fuse and to be loosed core block outer wall, and match with gathering sill of loosing core, described rotating shaft installs swing pinion, in moving clamping plate, tooth bar of loosing core is set, tooth bar of loosing core is meshed with swing pinion, tooth bar of loosing core is moved back and forth by powered belt action.
The invention discloses the rotary loose-core injection mould of a kind of ripple big syphon part, when loosing core, first run downwards by injection machine powered belt moving mold dynamic model part, moving platen is separated with solid plate die sinking, swivel plate follows dynamic model part to run downwards, in this die sinking process, because guide plate is arranged on solid plate, do not move, and enlarging fuse block of loosing core to be arranged on swivel plate and then dynamic model componental movement, therefore, stretch out the loose core axis of rolling of block two side of enlarging fuse to coordinate with gathering sill of loosing core, rolled along upper straight guide groove before this, now enlarging fuse block of loosing core is temporarily motionless, mould continues die sinking, enlarging fuse loose core block continue and then descending, to lower inclined guide groove place, the axis of rolling rolls along the track of lower inclined guide groove, enlarging fuse block of loosing core is driven outwards to slide, enlarging fuse block of loosing core drives enlarging fuse to loose core, loose core to enlarging fuse, rack work of loosing core is driven again by power, driven rotary pinion rotation, swivel plate on swing pinion driven rotary axle rotates, swivel plate drives above-mentioned whole enlarging fuse pulled core structure through gangbar, drive elbow fuse rotary core pulling, elbow fuse is extracted out smoothly from ripple big syphon part, finally by the ejecting mechanism of mould or manipulator, shaping ripple big syphon part is taken out outside mould, the demoulding completes.The enlarging fuse of this programme adopts the axis of rolling to coordinate drive to loose core with gathering sill, and elbow fuse adopts rotary core pulling, and both are combined with each other, compact conformation, reduce mould volume, reduces production cost.
The rotary loose-core injection mould of ripple big syphon part of the present invention, described power is oil cylinder or motor, as the machine of falling para-electric, servomotor etc.The described axis of rolling installs bearing, has had bearing, the axis of rolling rolls smooth.Described enlarging fuse is loosed core mounting limit plate in block outer end wall, mounting limit block on the two side of limiting plate, and described guide plate arranges stopper slot, and limited block matches with stopper slot, the mating shapes of described stopper slot and gathering sill of loosing core.Limited block and stopper slot carry out spacing to the axis of rolling and gathering sill of loosing core, and the action that makes to loose core is more accurate.Described enlarging fuse is loosed core under block and is arranged on T-shaped guide block, and T-shaped guide block is fixed on swivel plate, mounting plate on swivel plate, fixed head connect gangbar, had T-shaped guide block, enlarging fuse loose core block slide more steady, smooth and easy, gangbar is connected with fixed head, and interlock is reliable.The concrete technical scheme of described formation enlarging fuse has multiple, such as wherein one for comprising a conical surface insert, conical surface insert arranges oblique chute and oblique I-shaped, and oblique chute and oblique I-shaped arrange enlarging piece, and enlarging piece matches with the enlarging of ripple big syphon part.Be beneficial to the oblique sliding effect of oblique chute and oblique I-shaped, enlarging is deviate from smoothly, and this class formation is just becoming the common technology as the enlarging demoulding, also has similar patent application, no longer describes this structure in detail.
