Embodiment
The following is specific embodiments of the invention and by reference to the accompanying drawings, the technical scheme of the present invention is further described, but the present invention is not limited to these embodiments.
Having barb class part 18 in the present embodiment is example taking bung.
The injection mold originally with barb class part comprises cover half body 1, fixed mould core 2, movable mold core 3 and driving mechanism.
Specifically, fixed mould core 2 is fixed on cover half body 1. As preferentially, fixed mould core 2 is positioned on the medullary ray of injection mold. Movable mold core 3 is set in fixed mould core 2. Fixed mould core 2 and movable mold core 3 all have molding surface, and in sequential like and become the molding surface corresponding with part 18 between fixed mould core 2 molding surface with movable mold core 3 molding surface.
Movable mold core 3 has barb forming tank 4; Namely the hook portion 19 of part 18 is shaping on movable mold core 3.
Driving mechanism is arranged between movable mold core 3 and cover half body 1, and it can drive movable mold core 3 axially reciprocating, part 18 and movable mold core 3 can be made to be synchronized with the movement, it is achieved part 18 departs from fixed mould core 2; Movable mold core 3 can be made again to reset, it is achieved in sequential like between fixed mould core 2 molding surface and movable mold core 3 molding surface. Cover half body 1 is provided with the induction trunk 1 being connected with space between part 18 and fixed mould core 2.
In order to improve the stability of movable mold core 3 motion and ensure the movable mold core 3 after resetting and the consistence of the front position of movement, having annular guide path 6 between cover half body 1 and fixed mould core 2, the bottom of movable mold core 3 is embedded in annular guide path 6. As prioritization scheme, fixed mould core 2 outer side has cylindrical surface 7, and in movable mold core 3, side also has cylindrical surface 7, and movable mold core 3 cylindrical surface 7 relies on fixed mould core 2 cylindrical surface 7 phase. Meanwhile, fixed mould core 2 outer side has the outer oblique conical surface 8, side has in movable mold core 3 and can with the outer oblique conical surface 8 lean in the tiltedly conical surface 9 corresponding with the outer oblique conical surface 8.
Driving mechanism comprises return spring 10 and is arranged on cover half body 1 the pneumatic actuation assembly that can lean with movable mold core 3 end face, and cover half body 1 is equipped with reset lever 11, and one end of reset lever 11 is connected with movable mold core 3; One end and the cover half body 1 of return spring 10 lean, and the other end of return spring 10 and the other end of reset lever 11 lean. It is believed that reset lever 11 comprises the body of rod 12 and bolt 13 with annular bead, the body of rod 12 is threaded with the body of rod 12 through cover half body 1, bolt 13 through flexible mould; This structure facilitates the installation of the parts such as reset lever 11, spring. In order to make mould structure compacter, cover half body 1 having groove 14 of stepping down, this structure can shorten the length of reset lever 11, makes in the body of rod 12 position cover half body 1; One end of return spring 10 is resisted against on the bottom surface of groove 14 of stepping down, and the other end of return spring 10 and the annular bead of the body of rod 12 lean. In order to improve the stability that movable mold core 3 resets, this driving mechanism comprises 3��8 groups of reset levers 11 and spring assembly; All reset levers 11 and spring assembly are uniformly distributed along movable mold core 3 circumference.
Pneumatic actuation assembly comprises the annular air reservoir 15 being positioned on cover half body 1, and being provided with in annular air reservoir 15 can annularly air reservoir 15 sidewall sealing-ring 16 in axial sliding;The induction trunk 2 17 having in cover half body 1 and be connected bottom annular air reservoir 15. This structure can make movable mold core 3 evenly by power, it is to increase movable mold core 3 stability of motion. The induction trunk 2 17 of this pneumatic actuation assembly is connected with compressed air reservoir, and in annular air reservoir 15 during air feed, pressurized air promotes sealing-ring 16 to move, and then promotes movable mold core 3 to move; When stopping in annular air reservoir 15 after air feed, movable mold core 3 resets under return spring 10 elastic force effect.
According to practical situation, pneumatic actuation assembly can adopt following scheme to replace: pneumatic actuation assembly comprises the annular spacing groove being positioned on cover half body 1, being provided with elastic hollow in annular spacing groove and drive circle, elastic hollow drives and is fixed with the inlet pipe with intracavity inter-connection on circle.
According to practical situation, driving mechanism can adopt following scheme to replace: driving mechanism comprises some along the circumferential equally distributed cylinder of movable mold core 3, and the cylinder body of described cylinder is fixed on cover half body 1, and piston rod is fixedly connected with movable mold core 3. In order to improve movable mold core 3 stability of motion, the quantity of cylinder is 3��8 and is uniformly distributed along movable mold core 3 circumference.
Induction trunk 1 extends in fixed mould core 2 and the outlet of induction trunk 1 is positioned on the outer tiltedly conical surface 8 of fixed mould core 2. After driving mechanism promotes movable mold core 3 to move laterally, form gap between the interior oblique conical surface 9 and the outer oblique conical surface 8, and between fixed mould core 2 cylindrical surface 7 and movable mold core 3 cylindrical surface 7, form higher stopping property, avoid compressed air leakage; Thus pressurized air enters the room, chamber between part 18 and fixed mould core 2 by above-mentioned gap.
According to practical situation, the structure of induction trunk 1 can adopt following scheme to replace: the outlet of induction trunk 1 is positioned in fixed mould core 2 part 18 molding surface, and exit is provided with the stifled head of energy shutoff outlet, and stifled head is fixedly connected with movable mold core 3. Movable mold core 3 moves and drives stifled head motion to realize connection or the cut-off of induction trunk 1.
