Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 3, the injection mold in the present embodiment has the same structure as the conventional injection mold except for the main nozzle. As shown in fig. 3, the main nozzle is installed in a cover plate 5, and a cover plate flange 4 is detachably attached to the top of the cover plate 5, and the cover plate flange 4 is used for positioning between the injection mold and the injection molding machine. In the prior art, main base nozzle formula structure as an organic whole, as shown in fig. 3, the flange of main base nozzle is located the lower part of main base nozzle, consequently, when needs change main base nozzle, need dismantle apron 5 from injection mold, because the quantity of the part of being connected with apron 5 on the injection mold is very much, the work load of dismantling apron 5 is not as good as the last mould of dismantling injection mold, consequently, wastes time and energy, and injection mold maintenance cost is high.
As shown in fig. 1, the split main base nozzle of the present embodiment includes a nozzle head 1, a nozzle body 2 and a flow passage hole 3; one end of the nozzle body 2 is a mould connecting end, and the other end of the nozzle body 2 is detachably connected with the nozzle head 1; the flow passage hole 3 penetrates through the mouth body 2 and the mouth head 1 in sequence.
As shown in fig. 1 and 3, the spherical surface 113 of the main nozzle contacting with the barrel (a device for injecting plastic, not shown in the figure) of the injection molding machine is located at the top of the nozzle 1, therefore, after the spherical surface 113 is damaged, only the cover plate flange 4 needs to be detached from the cover plate 5, and then the nozzle 1 is detached from the nozzle body 2, because the cover plate flange 4 is only bolted with the cover plate 5, compared with detaching the cover plate 5, the workload of detaching the cover plate flange 4 is greatly reduced.
As shown in fig. 1, in the present embodiment, an end surface of one end of the nozzle body 2 facing the nozzle head 1 is provided with an internal thread; the end of the nozzle head 1 facing the nozzle body 2 is provided with an external thread matched with the internal thread. Of course, the opposite is also possible, i.e. an internal thread is provided on the tip 1 and an external thread is provided on the body 2.
As shown in fig. 1 and 2, in the present embodiment, an end of the nozzle tip 1 facing away from the nozzle body 2 has a wrench portion 111 for facilitating rotation of the nozzle tip 1. Through setting up spanner portion 111, can use tools such as spanner, increase the application of force radius of rotating mouth 1, increased moment promptly to be convenient for dismantle mouth 1 from mouth body 2. The wrench portion 111 may be a regular polygonal type, or may be a plurality of insertion holes formed in the outer peripheral wall of the tip 1 or the tip end surface of the tip 1.
As shown in fig. 2, in the present embodiment, the outer peripheral wall of the wrench portion 111 has a polygonal profile. Can be quadrangle, pentagon or hexagon, etc., and the utility model does not limit the same.
As shown in fig. 2, in the present embodiment, the polygonal surface is a regular hexagon, so that it is very convenient to operate with a common hexagon wrench.
