A kind of knock-out gear; it comprises female slide block, the first sub-slide block and the second sub-slide block; the described first sub-slide block is fixed on the front end face of described female slide block; the described second sub-slide block is slidingly located on the described first sub-slide block; and its front end allows this first sub-slide block expose; tail end is connected with the front end face of described female slide block by a time-delay driven unit; described time-delay driven unit just drives the second sub-slide block slip after allowing described female slide block drive the first sub-slide block slip certain distance, and the rear end face of described female slide block is provided with pull bar.Rational in infrastructure, be easy to processing, reduce cost.
Described time-delay driven unit comprises spring element and drive rod, the rear end face of described female slide block is provided with recess, the head of described drive rod is fixed on the described second sub-slide block, afterbody runs through described female slide block, and be provided with the hook part suitable in end after stretching into described recess certain distance with this recess, the position of corresponding described drive rod is provided with and the suitable cavity of described spring element appearance profile in the front end face of described female slide block, described spring element is inserted this cavity, and an end of this spring element is conflicted on the described second sub-slide block, and the other end is conflicted on described female slide block.Cooperate and stablize the reliability height.
Described spring element is spring or elastic rubber.Simple in structure, long service life.
The beneficial effects of the utility model are: the utility model reasonable in design, two sub-slide blocks are twitched stage by stage, realization will be divided into two with the adsorption area of injecting products, reduce the absorption dynamics between slide block and the injecting products greatly, avoid taking place pulling the phenomenon that goods cause the moulding distortion because of slide block slides, depanning is effective, and when the first sub-slide block slides, the second sub-slide block is motionless for the time being, function with location injecting products, further stop injecting products and be adsorbed on problem on the slide block, guarantee product quality; Overall structure is simple in addition, applicable to multiple kinds of molds, and effectively simplifies mould structure, reduces Mould design time and machining period, shortens opening period, reduces die cost.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the decomposition texture schematic diagram of Fig. 1;
Fig. 3 is the complete section structural representation of Fig. 1.
The specific embodiment
Referring to Fig. 1; Fig. 2 and Fig. 3; a kind of knock-out gear that present embodiment provides; it comprises female slide block 1; the first sub-slide block 2 and the second sub-slide block 3; the described first sub-slide block 2 is fixed on the front end face of described female slide block 1; the described second sub-slide block 3 is slidingly located on the described first sub-slide block 2; and its front end allows this first sub-slide block 2 expose; tail end is connected with the front end face of described female slide block 1 by a time-delay driven unit 4; described time-delay driven unit 4 just drives second sub-slide block 3 slips after allowing described female slide block 1 drive the first sub-slide block 2 slip certain distances, and the rear end face of described female slide block 1 is provided with pull bar 5.In the utility model, just driving the second sub-slide block 3 after the distance with the first sub-slide block 2 design slip 10mm slides, among other embodiment, can come just to drive the second sub-slide block 3 after its distance of how long will sliding of respective settings according to the length that the first sub-slide block 2 exposes and slide, slide just to drive the second sub-slide block 3 after guaranteeing the first sub-slide block 2 and injecting products separating fully.Overall construction design is reasonable, the first sub-slide block 2 slides and the second sub-slide block 3 is twitched stage by stage, realization will be divided into two with the adsorption area of injecting products, reduce the absorption dynamics between slide block and the injecting products greatly, avoid taking place pulling the phenomenon that goods cause the moulding distortion because of slide block slides, depanning is effective, and when the first sub-slide block 2 slides, the second sub-slide block 3 is motionless for the time being, function with location injecting products, further stop injecting products and be adsorbed on problem on the slide block, guarantee product quality; Overall structure is simple in addition, applicable to multiple kinds of molds, and effectively simplifies mould structure, reduces Mould design time and machining period, shortens opening period, reduces die cost.
