Abstract
The utility model discloses a be applied to plastic mould's exhaust structure, include: the runner main body is arranged on the plastic mold and used for plastic in a fluid state to flow in the runner main body, and one or two tail ends of the runner main body are conical with the diameter gradually reduced outwards; and the exhaust channel is arranged on the plastic mold and communicated with the tail end of the runner main body. Because the end of the runner main body is designed into the conical shape with gradually reduced diameter outwards, when the plastic in the fluid state is injected into the runner main body, the air in the runner main body can be rapidly discharged, and the plastic is prevented from breaking due to the obstruction of the air in the flowing process; meanwhile, when the plastic flows to the tail end of the runner main body, the diameter or the thickness of the plastic is gradually reduced, so that the plastic can be quickly solidified, the plastic cannot overflow from the tail end of the runner main body into the exhaust channel, and the problem that the mold is easy to leak glue due to too deep exhaust is solved.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of plastic mould.
Background technology
As everyone knows, the shaping mode of plastic-injection is adopted to produce the production efficiency that product can accelerate product greatly, reduce production cost, but along with the fast development of plastic cement industry, price and employment cost are all in increase, making to save time the production cycle shorten to reduce costs, more effective exhaust structure must be designed to shorten the production cycle of injection mo(u)lding.
The exhaust structure of existing plastic mould makes mould in injection moulding process, cause being in the plastic cement fracture of fluid state because there is air in flow path bodies, can not be connected; Or because flow path bodies is long, be vented dark and caused the plastic cement of flow path bodies end not solidify in time and to overflow in exhaust passage, formed and leak glue phenomenon, material is produced in waste.
Utility model content
In order to solve the problem, it is simple that the purpose of this utility model is to provide a kind of structure, both can discharge the air in flow path bodies fast, and avoid plastic cement runner to rupture, and also can not cause the plastic mould exhaust structure of Lou glue because of being vented deeply simultaneously.
The utility model is the technical scheme that its technical problem of solution adopts:
Be applied to an exhaust structure for plastic mould, comprise:
Flow path bodies, described flow path bodies to be opened on plastic mould and within it to flow for the plastic cement being in fluid state, simultaneously one or two end of this flow path bodies diametrically diminish gradually outward coniform;
Exhaust passage, this exhaust passage to be opened on plastic mould and to be connected with the end of described flow path bodies.
As the improvement of technique scheme, two ends of described flow path bodies are communicated with an exhaust passage respectively.
As the further improvement of technique scheme, it is coniform that two ends of described flow path bodies all diametrically diminish outward gradually.
The beneficial effects of the utility model are: because the utility model is coniform by what become diametrically to diminish gradually outward by the tip designs of flow path bodies, therefore when the plastic cement being in fluid state injects flow path bodies, promptly the air in flow path bodies can be discharged, avoid plastic cement because of the obstruct of air, phenomenon of rupture to occur at flow process; When simultaneously plastic cement flows to the end of flow path bodies, diameter or the thickness of plastic cement diminish gradually, thus can quick solidification, and therefore plastic cement can not spill into exhaust passage from the end of flow path bodies, solves mould because being vented the problem of deeply and easily leaking glue.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of exhaust structure being applied to plastic mould, comprise and being opened on mould and the flow path bodies 1 flowed therein for the plastic cement being in fluid state, this flow path bodies 1 at least offers a plastic cement inlet so that plastic cement injects in it, an end 10 or two ends 10 of described flow path bodies 1 are connected with the exhaust passage 2 be connected with its inside, preferably, two ends of described flow path bodies 1 are connected to exhaust passage 2, therefore when plastic cement injects flow path bodies 1, air in flow path bodies 1 can be expelled to rapidly in exhaust passage 2 by two end 10, in order to air can be discharged better, avoid plastic cement runner to rupture or occur to leak glue phenomenon, in the utility model, it is coniform that end 10 direction outward that described flow path bodies 1 is connected with exhaust passage 2 diametrically diminishes gradually, here, can of flow path bodies 1 end 10 be designed to coniform, also can two end 10 be designed to coniform, or multiple ends 10 of flow path bodies 1 are designed to coniform, specifically can according to needs of production unrestricted choice.Because the utility model is coniform by what to be designed to by the end 10 of flow path bodies 1 diametrically to diminish gradually outward, therefore when the plastic cement being in fluid state injects flow path bodies 1, promptly the air in flow path bodies 1 can be discharged, avoid plastic cement because of the obstruct of air, phenomenon of rupture to occur at flow process; When plastic cement flows to the end 10 of flow path bodies 1 simultaneously, diameter or the thickness of plastic cement diminish gradually, thus can quick solidification, therefore plastic cement can not spill into exhaust passage 2 from the end 10 of flow path bodies 1, solves mould because being vented the problem of deeply and easily leaking glue.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
