Fig. 2 is the A place enlarged drawing of Fig. 1.
Fig. 3 is the decomposing state sectional structure schematic diagram of Fig. 1.
The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1 ~ shown in Figure 3,1. the cold flow guidance tape, 2. the constant temperature oil duct, 3. injection groove, 4. injection port, 5. the stub bar plate, 6. go up the stub bar blind hole, 7. the stub bar groove, 8. injection mold cavities, 9. descend stub bar hole, 10. stub bar blind hole in through hole, 12. side through hole, 13. in the injection template, 11..
Rubber injection is got the stub bar device, mainly comprises injection template 10 and is arranged on the cold flow guidance tape 1 of injection template top, and this cold flow guidance tape can be injected template 10 relatively and do upper and lower motion deciliter under machinery control.
Described cold flow guidance tape 1 is provided with a plurality of injection ports 4, on each injection port all is, the through-hole structure of following perforation, each injection port place at cold flow guidance tape 1 end face is equipped with injection groove 3, can be used for holding and annotate mouth to carry out the injection of rubber raw materials, each injection port 4 one side all is provided with two and goes up stub bar blind hole 6, go up the stub bar blind hole for these two and all be designed to the back taper blind hole, and be that the center is made symmetry and distributed with injection port 4, the opening of last stub bar blind hole 6 is positioned at the bottom surface of cold flow guidance tape 1, the design of its back taper mainly is to make stub bar can follow cold flow guidance tape 1 to promote together, to make things convenient for separating fast of stub bar and product; Also be provided with constant temperature oil duct 2 in the described cold flow guidance tape 1, can feed the fluid of suitable temperature, the circulation during with the injection of promotion rubber raw materials according to need of work.
Described injection template 10 end faces be provided with cold flow guidance tape 1 on each injection port 4 equal corresponding stub bar groove 7 that communicate and be communicated with two following stub bar holes 9 of stub bar groove simultaneously, these two following stub bar holes are corresponding with two last stub bar blind hole 6 positions on the cold flow guidance tape 1, be each down stub bar hole 9 all with each on stub bar blind hole 6 be on the same vertical line, the while is connected with the injection mold cavities 8 of injecting template 10 bottom surfaces again in two following stub bar holes; Described each stub bar groove 7 middle part are equipped with the middle stub bar blind hole 13 over against injection port 4.
Be provided with stub bar plate 5 between described injection template 10 and the cold flow guidance tape 1, this stub bar plate is provided with the corresponding middle through hole 11 that is communicated with each injection port 4 and correspondingly is communicated with the side through hole 12 that each goes up stub bar blind hole 6, and the while is connected with corresponding stub bar groove 7 again for through hole 11, side through hole 12 in this.Therefore, when rubber raw materials injects injection port 4, and enter stub bar groove 7, middle stub bar blind hole 13, following stub bar hole 9 by middle through hole 11 successively, and enter stub bar blind hole 6 when all filling with by side through hole 12, promptly formed stub bar, simultaneously, rubber raw materials is again through stub bar hole 9 injection injection mold cavities 8 are interior to form product down.
The utility model is because the existence of stub bar plate 5, the stub bar of product all can firm attachment on the stub bar plate, therefore only need take off stub bar plate 5, all all can be taken off by disposable attached to the stub bar on this stub bar plate, replacing with new stub bar plate 5 then can come into operation again, and the stub bar plate that has a stub bar in addition cleaning get final product, this is got, and the stub bar process has greatly been saved the time undoubtedly, energy, improved operating efficiency, heat is not suitable for possessing the injection template 10 of voluminous product injection mold cavities 8 and injects.
