Abstract
The invention provides an exit mechanism applied in a plastic mold for production of a product with an annular barb structure. The exit mechanism is characterized by comprising: a chocking block; at least two angle pins; at least two slider inserts; at least two inclined guide pillars; an opening and closing controller; a first limit pull rod; and a second limit pull rod. By controlling the order of mold opening, during the first mold opening, the chocking block first exits from a cavity center, and the motion drives the horizontal movement of the angle pins towards the center of the mold cavity through T-shaped grooves for exiting from the barb of a product first diagonal. During the second mold opening, the chocking block and the angle pins continue exiting from the mold cavity downward so as to generate exit space for the slider inserts to exit. Driven by the inclined guide pillars, the slider inserts move toward the center of the mold cavity so as to exit from the barb of a product second diagonal. The exit mechanism of the invention solves the technical problem that exit becomes impossible when the product has an annular barb structure in the prior art, and is characterized by clever design and stable exit.

[specific embodiment]
The below combines accompanying drawing that preferred embodiments 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, be used to produce one have a square annular barb product 10, this mould comprises a caster 1000, a male model plate 2000, a male model board 3000 and a bottom plate 4000; It is characterized in that this drawing-out mechanism comprises:
A branch of 100; Its main body is that the cross section is foursquare column structure; Its main body top is provided with four inclined-planes; Be respectively arranged with a T type chute on two inclined-planes of first opposite side, its upper surface is inserted the center of mold cavity and is participated in this product 10 of moulding when matched moulds, 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 on the T type chute that " eight " font is movably set in these bundle piece 100 first opposite side inclined-planes respectively; These taper pin 200 upper ends are provided with the head of a bending; Participate in the barb at these product 10 first diagonal angles of moulding during matched moulds; This taper pin 200 offers a horizontal through hole and wears a pin 210, and this taper pin 200 can be connected on this male model plate 2000 slidingly;
Two slide blocks are gone into son 300; This slide block is gone into son 300 and is movably set in respectively on the inclined-plane of these bundle piece 100 second opposite side; This slide block is gone into son 300 and is had a horizontal main body 320 and an oblique arm 330; The horizontal main body 320 that this slide block is gone into son 300 can be arranged on this male model plate 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 these bundle piece 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, participates in the barb at these product 10 second diagonal angles of moulding during matched moulds respectively;
Two Angle Pins 310,310 pairs of this Angle Pins should slide block be gone into the oblique guide hole 340 on the son 300 and are fixedly arranged on this male model board;
One shutter 400, it connects this caster 1000 and this male model plate 2000 when matched moulds;
First limit pull rod 500; The one of which end is fixedly arranged on this male model board 3000; Its other end is provided with a step surface, and this step surface is movably set in the empty avoiding space of this bottom plate 4000, also is arranged with a spring 510 on it; This spring 510 connects this male model board 3000 and this bottom plate 4000, and this spring 510 is compressed when matched moulds;
