The specific embodiment
For principle and the structure that further specifies the utility model, combine accompanying drawing that the preferred embodiment of the utility model is elaborated at present.
See also Fig. 2 to shown in Figure 3, the needle valve TOP-TIP of the utility model comprises needle 1, a needle fixed head 2, nozzle 3, a needle drive unit 4 and a thrust unit 5, can also comprise a hot runner manifold 6.
The top of said needle 1 is vertically connected on the said needle fixed head 2, and said needle 1 passes hot runner manifold 6 and insert in the said nozzle 3 bottom, and the quantity of said needle 1 is a plurality of.
Please combine to consult Fig. 4 to shown in Figure 7; The said needle fixed head 2 two relative outsides can be respectively arranged with the oblique projection 21 of a plurality of oblique extensions; Said oblique projection 21 can obliquely run through the short transverse of said needle fixed head 2; Also be provided with the needle fixing hole 22 identical on the said needle fixed head 2, vertically to connect a plurality of said needles 1 simultaneously with the quantity of said needle 1.
Said needle drive unit 4 is provided with the output shaft 41 that can on the parallel direction of said needle fixed head 2, stretch, and said needle drive unit 4 can be hydraulic pressure commonly used or air pressure driving mechanism.
See also Fig. 4 to shown in Figure 7; Said thrust unit 5 and said needle fixed head 2 are parallel and can obliquely be slidingly connected in the outside of said needle fixed head 2; The output shaft 41 of said needle drive unit 4 links to each other with said thrust unit 5, thereby moves up and down to drive said needle 1 through the said needle fixed head 2 of said thrust unit 5 promotions.Said thrust unit 5 can comprise two first push pedals 51 that parallel interval is provided with, and can also comprise one second push pedal 52.
Said two first push pedals 51 are slidingly connected at the relative both sides of said needle fixed head 2 respectively; Said two first push pedals, 51 opposed inside are respectively arranged with a plurality of skewed slots parallel to each other 511; Said skewed slot 511 can obliquely run through the short transverse of said first push pedal 51, and said skewed slot 511 is 20 ° to 45 ° with the angular range of horizontal direction.Said oblique projection 21 is arranged on the said needle fixed head 2 and the adjacent outside of said first push pedal 51, and said oblique projection 21 is suitable with the shape of said skewed slot 511, to be connected slidably in the said skewed slot 511.
Said second push pedal 52 is vertically connected on an end of said two first push pedals 51 and links to each other with the output shaft 41 of said needle drive unit 4.
Said hot runner manifold 6 is arranged on the below of said thrust unit 5, and said nozzle 3 is connected the below of said hot runner manifold 6.
Below course of action when the needle valve TOP-TIP of the utility model used be described below.
When needs are opened said needle 1; Only need to start said needle drive unit 2; Make the output shaft 41 on it inwardly bounce back; And then spur said second push pedal 52 and move to direction away from said needle fixed head 2; Because cooperating of the oblique projection 21 on the skewed slot 511 in said first push pedal 51 and the said needle fixed head 2, so the oblique projection 21 on the said needle fixed head 2 can slide to oblique upper along said skewed slot 511, simultaneously again because said nozzle 3 has limited in the horizontal direction mobile of said needle 1; Move up so show as needle 1 in the vertical direction that said needle fixed head 2 drives on it, open when therefore having realized many needles 1 (this moment said needle fixed head 2 with the mated condition of said thrust unit 1 for as shown in Figure 6).
On the contrary; When needs with needle 1 closure when sealing said nozzle 3; Need to start said needle drive unit 2 equally; Make the output shaft 41 on it outwards extend; And then promote said second push pedal 52 and move to direction near said needle fixed head 2; Because cooperating of the oblique projection 21 on the skewed slot 511 in said first push pedal 51 and the said needle fixed head 2, so the oblique projection 21 on the said needle fixed head 2 can be along said skewed slot 511 to oblique slid underneath, simultaneously again because said nozzle 3 has limited in the horizontal direction mobile of said needle 1; Move down so show as needle 1 in the vertical direction that said needle fixed head 2 drives on it, therefore realized many needles 1 simultaneously closure seal said nozzle 3 (this moment said needle fixed head 2 with the mated condition of said thrust unit 1 for as shown in Figure 7).
Keying when the needle valve TOP-TIP of the utility model only needs a needle-valve drive unit just can control a plurality of needle; Fundamentally solved the stuck phenomenon that causes owing to needle is asynchronous; And this structure can not cause the increase of template thickness yet, is fit to the multi-cavity small sized product simultaneously yet.
Yet; The above is merely the preferable possible embodiments of the utility model; And the protection domain of unrestricted the utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content have been done changes, all be included in the protection domain of the utility model.
