[detailed description of the invention]
Below with accompanying drawing, better embodiment of the present invention is described in further detail.
Please refer to Fig. 1 to Fig. 9, drawing-out mechanism of the present invention, be applied to a plastic mould, there is for the production of one the product 10 of square annular barb, this mould comprises caster 1000, male template 2000, male model board 3000 and a bottom plate 4000, it is characterized in that, this drawing-out mechanism comprises:
A branch of piece 100, its main body is cross section is foursquare column structure, its body top is provided with four inclined-planes, two inclined-planes of the first opposite side are respectively arranged with a T-shaped chute, mold cavity is inserted in its upper surface center when matched moulds participates in this product 10 shaping, and its lower end is fixedly arranged on this bottom plate 4000;
Two taper pins 200, the back of this taper pin 200 is provided with a T-type structure, two these taper pins 200 are movably set on the T-shaped chute on this bundle block 100 first opposite side inclined-plane in " eight " font respectively, this taper pin 200 upper end is provided with the head of a bending, the barb at this product 10 first diagonal angle shaping is participated in during matched moulds, this taper pin 200 offers a horizontal through hole and wears a pin 210, makes this taper pin 200 can be connected in this male template 2000 slidingly;
Two slide blocks enter son 300, this slide block enters son 300 and is movably set on the inclined-plane of this bundle block 100 second opposite side respectively, this slide block enters son 300 and has horizontal body 320 and an oblique arm 330, the horizontal body 320 that this slide block enters son 300 can be arranged in this male template 2000 respectively slidingly, and offer an oblique guide hole 340 respectively, this oblique arm 330 extends to mold cavity, match with the inclined-plane of this bundle block 100 second opposite side in the angle of inclination of this oblique arm 330, its upper end is respectively equipped with the head of a bending, the barb at this product 10 second diagonal angle shaping is participated in respectively during matched moulds,
Two Angle Pins 310, this Angle Pin 310 is to should enter the oblique guide hole 340 on son 300 and be fixedly arranged on this male model board by slide block;
One shutter 400, it connects this caster 1000 and this male template 2000 when matched moulds;
First limit pull rod 500, its one end is fixedly arranged on this male model board 3000, its other end is provided with a step surface, this step surface is movably set in the empty avoiding space of this bottom plate 4000, it is also arranged with a spring 510, this spring 510 connects this male model board 3000 and this bottom plate 4000, and when matched moulds, this spring 510 is compressed;
Second limit pull rod 600, its one end is fixedly arranged on this male model board 3000, and its other end is provided with a step surface, and this step surface is movably set in an activity space of this male template 2000.
During matched moulds, the bending head that the bending head that the center that mold cavity is inserted in the upper end of this bundle block 100 participates in this product shaping 10, two these taper pins 200 and two these slide blocks enter sub 300 fits in the square annular barb of this product 10 of type.
During first time die sinking, due to the effect of this shutter 400, this male template 2000 temporarily cannot be separated with this caster 1000, this bottom plate 4000 and this male model board 3000 separate by the elastic restoring force of the spring 510 on this first limit pull rod 500, thus this bundle block 100 first exits die cavity downwards, the motion that this bundle block 100 exits downwards simultaneously drives again this taper pin 200 to draw close to die cavity central motion in the horizontal direction, the bending head portion of this taper pin 200 exits the barb at this product 10 first diagonal angle respectively, until the step surface of this first limit pull rod 500 fastens the upper limit plane of this activity space on this bottom plate 4000, first time die sinking terminates.
During second time die sinking, because this first limit pull rod 500 fastens the upper limit plane of this activity space of on this bottom plate 4000, this male model board 3000 is separated with male template 2000, so this bundle block 100 exits mold cavity downwards with this taper pin 200 simultaneously, this slide block is entered son 300 by the Angle Pin 310 on this male model board 3000 to be promoted to die cavity central horizontal, the bending head portion that this slide block enters son 300 exits the barb at this product 10 second diagonal angle respectively, until the step surface of this second limit pull rod 600 fastens the lower limit plane of this activity space in this male template 2000, second time die sinking terminates.
During third time die sinking, the step surface of this second limit pull rod 600 fastens the lower limit plane of this activity space in this male template 2000, and this shutter 400 is opened, and this male template 2000 is separated with this caster 1000, is taken out by this product 10.
It is noted that the invention is not restricted to above-mentioned embodiment, any simple modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, equivalent variations and modification, all fall within the scope of protection of the present invention.
