Abstract
The utility model provides a feeding structure of mould, includes the feed nozzle of mould, lower mould and ox horn structure, it is provided with die cavity and cast feed liquid runner to go up between mould and the lower mould, the die cavity passes through the feed nozzle of ox horn structure and is connected with the transition runner, transition runner and cast feed liquid runner intercommunication, the feed nozzle and the transition runner of ox horn structure all set up on the mold insert, the mold insert setting on the lower mould, the utility model has the advantages of simple structure and reasonable design, accomplish the back when moulding plastics, the thimble is when ejecting mould, and the pushing force of thimble just can be easily pushes up feed nozzle and the die cavity department of linking to each other and break to the messenger moulds a drawing of patterns, moulds like this just can not produce the clout, reduces surperficial pan feeding line, and the mouth of a river is clean neat, not only can save material, reduce the cost of moulding plastics of stick, simultaneously, reducible artifical process and cost of rejecting the clout still, but after the completion of moulding plastics directly package, showing the benefit of improving production.
Description
Technical field
This utility model relates to a kind of technical field of mold, the feeding structure of especially a kind of mould, is mainly used in die industry.
Background technology
When plastic injection mo(u)lding, for ensureing the outward appearance of plastic, existing injection forming mold adopts submarine feeding structure mostly, so-called submarine feeding structure, it it is exactly the inner surface that the feed nozzle on mould is arranged on plastic, such injection moulding plastic outer surface out will not leave behind material mouth vestige, thus ensureing that the outer surface of plastic is attractive in appearance, but when mold releasability, one section of waste material can be remained accordingly in centre hole, this not only wastes raw material, add the injection moulding cost of single-piece plastic, simultaneously, after injection moulding completes, product surface leave such as material stricture of vagina, need manually manually to reject, add one production process, the workload making line producers strengthens, reduce the productivity effect of plastic.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the feeding structure of the mould of a kind of simple in construction.
The technical solution of the utility model is: the feeding structure of a kind of mould, feed nozzle including upper die and lower die Yu Cornu Bovis seu Bubali structure, die cavity and cast material liquid flowing channel it is provided with between described upper mould and counterdie, described die cavity is connected with transition runner by the feed nozzle of Cornu Bovis seu Bubali structure, described transition runner connects with cast material liquid flowing channel, the feed nozzle of described Cornu Bovis seu Bubali structure and transition runner are arranged on mold insert, and described mold insert is arranged on counterdie.
The bigger end of feed nozzle of described Cornu Bovis seu Bubali structure is connected with transition runner, and the feed nozzle small end of described Cornu Bovis seu Bubali structure is connected with die cavity.
Being equipped with the arc groove of transition chute and Cornu Bovis seu Bubali structure on described mold insert, described arc groove constitutes the feed nozzle of described Cornu Bovis seu Bubali structure, and described arc groove stretches in transition chute, and described transition chute constitutes described transition runner.
The beneficial effects of the utility model are: simple in construction, reasonable in design, and after injection moulding completes, thimble is when ejecting plastic, just can be broken in feed nozzle and die cavity connecting place top by the top power of thimble easily, so that the plastic demoulding, such plastic would not produce clout, reduce surface pan feeding stricture of vagina, mouth of a river neatly and orderly, is possible not only to save material, reduces the injection moulding cost of single-piece, simultaneously, also can reduce the artificial operation rejecting clout and cost, can directly pack after injection moulding completes, significantly improve productivity effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of feeding structure of mould, feed nozzle 4 including upper die and lower die Yu Cornu Bovis seu Bubali structure, die cavity and cast material liquid flowing channel 1 it is provided with between described upper mould and counterdie, described die cavity is connected with transition runner 2 by the feed nozzle 4 of Cornu Bovis seu Bubali structure, described transition runner 2 connects with cast material liquid flowing channel 1, and feed nozzle 4 and the transition runner 2 of described Cornu Bovis seu Bubali structure are arranged on mold insert 3, and described mold insert 3 is arranged on counterdie.
The bigger end of feed nozzle 4 of described Cornu Bovis seu Bubali structure is connected with transition runner 2, and feed nozzle 4 small end of described Cornu Bovis seu Bubali structure is connected with die cavity.
Being equipped with the arc groove of transition chute and Cornu Bovis seu Bubali structure on described mold insert 3, described arc groove constitutes the feed nozzle 4 of described Cornu Bovis seu Bubali structure, and described arc groove stretches in transition chute, and described transition chute constitutes described transition runner 2.
Described in above-described embodiment and description is that principle of the present utility model and most preferred embodiment are described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.
