Abstract
The utility model discloses a runner device, including hot mouth, with runner main part that hot mouth is connected and locate the runner between runner main part and the mould cavity, be equipped with buffer gear in the runner main part. Through set up buffer gear in the runner main part, played the effect of partial pressure, reduce the speed that colloidal sol got into the runner, make the air among the mould cavity fully discharge to the air cladding is in colloidal sol and result in moulding plastics the product that forms and the gas line appears, and in addition, slower packing speed can obtain stable flow, avoids the production of injection, has effectively improved the aesthetic property and the product quality of product. The utility model discloses simple structure, the use is convenient, the effect is reliable, has satisfied the practical application needs conscientiously.
Description
Technical field
The utility model relates to injection mold field, is specifically related to a kind of flow passage device.
Background technology
Existing flow passage device is made up of hot mouth, runner and cold runner usually, and cold runner is connected to the cast gate of mold cavity, carries out product injection mo(u)lding.But due to melten gel, to enter die cavity medium velocity from cast gate too fast, the air in die cavity is caused to fail to discharge in time, cause coated air in colloidal sol and cause injection product surface to occur gas line, have impact on the outward appearance of product, reduce the quality of product, in addition, although the bending design of runner can delay to melt the time that glue enters die cavity, be conducive to shaping speed adjustment, but also increase the pressure loss on runner simultaneously, injection pressure also can shorten the mold use life-span comparatively greatly.
For the problems referred to above, as shown in Figure 1-2, a kind of flow passage device is proposed in prior art, it is by arranging multiple kink 2 ' at flow path bodies 1 ' place, to delay the time that colloidal sol enters cast gate 3 ', but take said structure not only to increase flow channel length, and increase the pressure loss on runner.
Utility model content
The utility model, in order to overcome above deficiency, provides a kind of flow passage device can effectively avoiding product surface to produce gas line.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of flow passage device, and comprise the flow path bodies that hot mouth is connected with described hot mouth and the cast gate be located between flow path bodies and mold cavity, described flow path bodies is provided with buffer gear.
Preferably, described buffer gear comprises an overflowing well, and the well head of described overflowing well is communicated with described flow path bodies.
Preferably, described overflowing well and describedly water hot mouth described in opening's edge and be oppositely arranged.
Preferably, described buffer gear comprises two overflowing well, and the well head of each described overflowing well is communicated with described flow path bodies.
Preferably, two described overflowing well are located at the both sides of described flow path bodies relatively.
Preferably, the well head size of two described overflowing well is different.
The flow passage device that the utility model provides, comprise the flow path bodies that hot mouth is connected with described hot mouth and the cast gate be located between flow path bodies and mold cavity, described flow path bodies is provided with buffer gear.By arranging buffer gear on flow path bodies, serve the effect of dividing potential drop, reduce the speed that colloidal sol enters cast gate, air in mold cavity can fully be discharged, in order to avoid gas line appears in the product that air-coating causes injection moulding to be formed in colloidal sol, in addition, slower filling speed can obtain stable flowing, avoid the generation of spraying, effectively improve aesthetic property and the product quality of product.The utility model structure is simple, easy to use, reliable for effect, conscientiously meets practical application needs.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment 1
As shown in Figure 3-4, the utility model provides a kind of flow passage device, and comprise the flow path bodies 2 that hot mouth 1 is connected with described hot mouth 1 and the cast gate 3 be located between flow path bodies 2 and mold cavity 4, described flow path bodies 2 is provided with buffer gear 5.By arranging buffer gear 5 on flow path bodies 2, serve the effect of dividing potential drop, reduce the speed that colloidal sol enters cast gate 3, air in mold cavity 4 can fully be discharged, in order to avoid gas line appears in the product surface that air-coating causes injection moulding to be formed in colloidal sol, in addition, slower filling speed can obtain stable flowing, avoid the generation of spraying, effectively improve aesthetic property and the product quality of product.The utility model structure is simple, easy to use, reliable for effect, conscientiously meets practical application needs.
Please emphasis with reference to Fig. 4, described buffer gear 5 comprises an overflowing well 51, the well head 52 of described overflowing well 51 is communicated with described flow path bodies 2, described overflowing well 51 and described cast gate 3 are oppositely arranged along described hot mouth 1, colloidal sol enters flow path bodies 2 from hot mouth 1, then enter overflowing well 51 and mold cavity 4 respectively from both direction, after the colloidal sol filling in overflowing well 51 is complete, now fill a part of colloidal sol in mold cavity, therefore the speed that colloidal sol enters cast gate can be gone up gradually, and product surface there will not be the problems such as gas line.
Embodiment 2
As different from Example 1, buffer gear 5 described in the present embodiment comprises two overflowing well 51, the well head 52 of each described overflowing well 51 is communicated with described flow path bodies 2, two described overflowing well 51 also can be located at the both sides of described flow path bodies 2 relatively, as shown in Figure 5, well head 52 size of two described overflowing well 51 is different, therefore colloidal sol fills up the speed difference of two overflowing well 51, the overflowing well 51 that well head 52 is large is first filled complete, fill complete after the overflowing well 51 that well head 52 is little, the colloidal sol that gone up gradually enters the speed of mold cavity, while further increasing dividing potential drop effect, speed is gone up also milder.
Although be illustrated embodiment of the present utility model in description, these embodiments just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
