Description
Technical field
The utility model relates to a kind of mould, and more particularly, it relates to, and a kind of melting charge charging efficiency is fast, easy arrives cavity bottom and the pipe fitting injection molding mold be evenly distributed.
Background technology
Pipe fitting injection molding mold is used to one-body molded pipe fitting, the mould of general making pipe fitting comprises cover half, dynamic model and core-pulling mechanism, cover half is provided with die cavity, core-pulling mechanism comprises core and driver, gap is formed between core and die cavity, the shape in gap is identical with the shape of pipe fitting, melting charge is passed in gap, again by its cooling forming, afterwards cooled pipe fitting is deviate from, when together making multiple pipe fitting, melting charge enters slowly, have a strong impact on shaping efficiency like this, and the melting charge entered well can not arrive the bottom of die cavity, cause pipe fitting defective, cause damage.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide fast, the easy arrival cavity bottom of a kind of melting charge charging efficiency and the pipe fitting injection molding mold be evenly distributed.
For achieving the above object, the utility model adopts following technical scheme, comprises cover half, dynamic model and core-pulling mechanism, cover half is provided with die cavity, core-pulling mechanism comprises core and driver, be formed with gap between core and die cavity, die cavity has four, and described cover half is provided with runner, four described die cavities pass through flow passage, described runner comprises connection runner, and described connection runner is positioned at cavity bottom, the middle part of described runner be melting charge enter place.
Preferably, runner is S-shaped, is communicated with cold burden groove in the middle part of described runner, and described cold burden groove is vertical with runner to be arranged.
Preferably, the circulation of runner two ends has auxiliary flow, and described auxiliary flow is communicated with spot pouring mouth, and described spot pouring mouth is communicated with die cavity.
Preferably, bottom runner, be provided with introduction hole, in described introduction hole, be equipped with thimble.
The utility model hinge structure is compared to be had: die cavity has four, cover half is provided with runner, four described die cavities pass through flow passage, runner comprises connection runner, be communicated with runner and be positioned at cavity bottom, the middle part of runner be melting charge enter place, melting charge enters into each die cavity by runner, and melting charge can be filled into gap from the connection runner being arranged in cavity bottom, arranging like this can make melting charge flow to each die cavity fast by runner, be communicated with runner simultaneously and also can ensure that melting charge easily can be filled into the bottom of die cavity, and such setting is melting charge distribution more even of bottom.

Detailed description of the invention
With reference to accompanying drawing, the utility model pipe fitting injection molding mold embodiment is described further.
A kind of pipe fitting injection molding mold, comprises cover half 2, dynamic model and core-pulling mechanism, cover half 2 is provided with die cavity 5, core-pulling mechanism comprises core 3 and driver, driver is cylinder 1, is formed with gap between core 3 and die cavity 5, and the shape in gap is identical with the shape of pipe fitting, melting charge is passed in gap, again by its cooling forming, deviate from by cooled pipe fitting afterwards, when deviating from, cylinder 1 drives core 3 first to deviate from pipe fitting, after deviating from completely Deng core 3, then by thimble, pipe fitting is released from die cavity 5.Die cavity 5 has four, cover half 2 is provided with runner 4, four described die cavities 5 are communicated with by runner 4, runner 4 comprises and is communicated with runner 43, be communicated with runner 43 and be positioned at bottom die cavity 5 (can see Fig. 4), the middle part of runner 4 be melting charge enter place, can ensure that melting charge is evenly distributed to a certain extent like this, melting charge enters into each die cavity 5 by runner 4, and melting charge can be filled into gap from the connection runner 43 be arranged in bottom die cavity 5, arranging like this can make melting charge flow to a not die cavity 5 fast by runner 4, be communicated with runner 43 simultaneously and also can ensure that melting charge easily can be filled into the bottom of die cavity 5, and such setting is melting charge distribution more even of bottom.
Runner 4 is S-shaped, and such is arranged so that melting charge has certain stroke, in melting charge course of conveying, make it steadily carry, can be comparatively even when melting charge is filled, and ensures the quality of pipe fitting; Be communicated with cold burden groove 41 in the middle part of runner 4, cold burden groove 41 is vertical with runner 4 to be arranged, and may produce cold burden at the nozzle of injection machine, and such mode arranges and cold burden first can be flow in cold burden groove 41, avoids cold burden to flow in die cavity 5, ensure that the quality of product.Ensure that melting charge can fully launch when entering runner 4, avoids runner 4 easily to block, ensure that entering fast of melting charge, more steady when simultaneously making melting charge enter simultaneously.
The circulation of runner 4 two ends has auxiliary flow 42, and auxiliary flow 42 is communicated with spot pouring mouth, and spot pouring mouth is communicated with die cavity 5, and while such arranging can ensure the connections of four die cavities 5, after die sinking, spot pouring mouth can automatic breaking, is conducive to automation mechanized operation.After removing cast gate, the vestige that plastic stays is not obvious, does not affect the attractive in appearance of plastic surface.And spot pouring mouth can be arranged on cover half 2, also can be arranged on dynamic model, also both can be arranged simultaneously, determine that the position of cast gate is very flexible.Auxiliary flow 42 also stores cold burden.
Be provided with introduction hole bottom runner 4, in introduction hole, be equipped with thimble, when die sinking, melting charge in runner 4 also can cool, and is connected with pipe fitting, so need thimble also to be ejected together by material wherein, ensure that pipe fitting can be deviate from smoothly, be also not easy to damage pipe fitting simultaneously.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to the above embodiments, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
