Description
Technical field
The invention belongs to injection molding technology field.
Background technology
Injection mold is a kind of instrument producing plasthetics, is also the instrument giving plasthetics complete structure and accurate dimension.Its occupation mode injects in the die cavity of injection mold by the material high pressure melted that is heated, and after cooling curing, obtains formed products.When existing moulding needs to manufacture screw thread, need to put into thread core in injection mold, after completing injection moulding, threaded moulding is taken out.
But because threaded moulding and thread core are in the state of threaded engagement, take off (screw thread preventing from destroying moulding) so moulding will be rotated from thread core after die sinking, but in actual production, moulding is taken off by artificial directly rotation on die casting machine, follow-up moulding can be stopped over like this produce, and the moulding temperature of just die sinking is very high, easily scalds workman.
Summary of the invention
The invention is intended to provide a kind of device not affecting the outer Leave out thread of machine that follow-up moulding is produced.
The device of the outer Leave out thread of the machine in this programme, be arranged on the cover half of injection machine, this cover half right-hand member has half groove for the formation of injection molding cavity, and this cover half inner transverse is furnished with the core groove communicated with half groove, is sliding combined with thread core in this core groove; Described cover half is the direction that core groove is vertical is furnished with removable bayonet lock, thread core side face has the annular slot coordinated with this bayonet lock; Described bayonet lock is affixed with the portable plate of band rake, and the inclined-plane of the wedge that the rake of this portable plate is arranged with cover half end face coordinates, and this wedge is fixedly connected with the push pedal outside cover half, this push pedal is fixed with the push rod that insertion cover half also can promote thread core.
Beneficial effect: (namely dynamic model is away from cover half after die sinking, both depart from relationship in a mutual action), push pedal is moved, make wedge promote portable plate to move (both rake/inclined-planes make moving horizontally of wedge be transformed into moving up and down of portable plate), thus bayonet lock exits from the draw-in groove of thread core, thread core obtains the free degree of horizontal direction movement, and then the movement of push pedal makes push rod promotion thread core move, thread core (now moulding is still coated on thread core) is released in core groove the most at last.After thread core cooling, moulding is rotated from thread core and takes off, meanwhile, the thread core that injection machine more renews can carry out the production of next moulding, the mode of the outer Leave out thread of this machine does not affect the production of follow-up moulding, enhance productivity, and after thread core cooling, Leave out thread can prevent workman from scalding.
Further, described push pedal has pilot hole, cover half is provided with the lead matched with pilot hole, ensure moving horizontally of push pedal.
Further, the face that described thread core is relative with push rod has push rod groove, the free end of push rod is positioned at this push rod groove, and push rod can be used for thread core to release core groove.
Further, described cover half has the spline groove perpendicular to core groove, bayonet lock is positioned at this spline groove, and the movement of bayonet lock double thread core is carried out spacing.
Further, be furnished with spring between described bayonet lock and spline groove bottom land, when after the contact that wedge departs from active board, bayonet lock can set back under the action of the spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device of the outer Leave out thread of embodiment of the present invention machine.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: cover half 1, dynamic model 2, thread core 3, draw-in groove 4, spline groove 5, bayonet lock 6, portable plate 7, wedge 8, push pedal 9, push rod 10, lead 11, moulding 12.
Embodiment is substantially as shown in Figure 1: de-external thread mechanism, comprises cover half 1 and dynamic model 2, cover half 1 right-hand member with half groove, the left end of dynamic model 2 with half groove, the involutory rear formation injection molding cavity of half groove on dynamic model 2 and cover half 1.
The inside of cover half 1 is provided with horizontal core groove, and this core groove communicates with injection molding cavity, and the direction that cover half 1 is inner vertical with core groove has the spline groove 5 communicated with core groove.Be sliding combined with thread core 3 in this core groove, the right-hand member of this thread core 3 is the thread forming portion that can insert injection molding cavity, in the middle part of thread core 3, side face has the draw-in groove 4 of annular.
Be furnished with bayonet lock 6 in the spline groove 5 of cover half 1, the bottom land of spline groove 5 is run through in the lower end of this bayonet lock 6, and the draw-in groove 4 of the lower end of this bayonet lock 6 and thread core 3 adapts.Be furnished with spring between bayonet lock 6 and spline groove 5 bottom land, the upper end of bayonet lock 6 is fixedly connected with by the portable plate 7 of bolt with cover half 1 end face.
The left end of thread core 3 has push rod groove, and the right-hand member of push rod 10 inserts in this push rod groove, and the left end of push rod 10 is fixedly connected with the push pedal 9 outside cover half 1, and this push pedal 9 is connected with straight-line feed motor.This push pedal 9 has pilot hole, and cover half 1 left end evagination forms lead 11, and this lead 11 inserts in pilot hole, and on lead 11, overcoat has spring.This push pedal 9 end face cylinder bolt is fixed with wedge 8, and this wedge 8 bottom surface flushes with cover half 1 end face, and the right-hand member of wedge 8 is inclined-plane (inclined-plane upward), and the one side that portable plate 7 is relative with wedge 8 has the rake coordinated with this inclined-plane.
The course of work of the present embodiment is: after die sinking, and dynamic model 2 is away from cover half 1, and moulding 12 still stays the place of thread forming portion of thread core 3.Push pedal 9 under the driving of straight-line feed motor, the elastic force that overcomes spring moves right, thus drives wedge 8 to move right, moving to right of wedge 8 makes portable plate 7 moves, and portable plate 7 moves and makes bayonet lock 6 moves, bayonet lock 6 exits from the draw-in groove 4 of thread core 3; After meanwhile, the thread core 3 that push rod 10 promotes to affranchise moves to right, and thread core 3 and moulding 12 release the core groove of cover half 1 the most at last, final grade for moulding 12 cools completely, manually moulding 12 is separated with thread core 3.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
