Abstract
The utility model relates to an injection mould structure provided with a nozzle capable of extending into a mould. The injection mould structure comprises an upper mould and a lower mould. The injection mould structure is characterized in that a through hole through which the nozzle of an injection molding machine can extend into the mould is arranged on the upper end face of the upper mould. The through hole is directly communicated with a runner plate inside the mould. By utilizing the technical scheme, the sprue in the prior art is removed, and the nozzle of the injection molding machine directly extends into the runner plate inside the mould through the through hole, so that the heat loss is less, the injection molding pressure is reduced, the pressure holding time of a plastic piece is shortened, the production period is shortened, the production efficiency is improved, and meanwhile, the waste is reduced and the production cost is lowered.
Description
Technical field
The utility model belongs to injection mold, is specifically related to a kind of injection mold structure that nozzle can stretch into mould inside that is provided with.
Background technology
Injection mold of the prior art all advances glue by sprue bushing, referring to Fig. 1, injection mold comprises cope match-plate pattern 1 and lower bolster 2, and its shortcoming is that sprue is longer, and heat loss is fast, injection pressure requires large, require accordingly the dwell time also will extend, the production cycle is very long, and production efficiency is low, produced simultaneously waste material is more, and cost is higher.
Summary of the invention
The utility model provides a kind of injection mold structure that nozzle can stretch into mould inside that is provided with in order to solve the technical problem of mentioning in background technology.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind ofly be provided with the injection mold structure that nozzle can stretch into mould inside, comprise cope match-plate pattern and lower bolster, it is characterized in that: described cope match-plate pattern upper surface has one and is used for the through hole that nozzle of injector stretches into mould inside.
Described through hole directly leads to the runner plate of mould inside.
After adopting above technical scheme: the utility model has been removed sprue bushing of the prior art, make nozzle of injector directly put in mould inside to runner plate by through hole, heat loss is few, injection pressure reduces, the dwell time of plastic reduces, and the production cycle shortens, and production efficiency improves, waste material reduces simultaneously, and production cost reduces.
Description of drawings
Fig. 1 is the structure cutaway view of die cavity contact-making surface in prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 2, a kind ofly be provided with the injection mold structure that nozzle can stretch into mould inside, comprise cope match-plate pattern 1 and lower bolster 2, cope match-plate pattern 1 upper surface has one and is used for the through hole 4 that nozzle of injector 3 stretches into mould inside, and described through hole 4 directly leads to the runner plate 5 of mould inside.
After adopting above technical scheme: the utility model has been removed sprue bushing of the prior art, make nozzle of injector directly put in mould inside to runner plate by through hole, heat loss is few, injection pressure reduces, the dwell time of plastic reduces, and the production cycle shortens, and production efficiency improves, waste material reduces simultaneously, and production cost reduces.
Claims (2)
