Abstract
The utility model discloses a tire mould tread exhaust structure, including the mould cavity surface, mould cavity sets up the decorative pattern piece die cavity that a plurality of is used for vulcanizing the tread configuration piece on the surface, be provided with the exhaust hole on the decorative pattern piece die cavity, and at every the edge of decorative pattern piece die cavity sets up marginal exhaust line respectively. The utility model discloses an exhaust effect when tire production is vulcanized has been ensured at the exhaust hole exhaust gas on tire mould surface to the setting, has improved off -the -shelf outward appearance quality.
Description
Technical field
The utility model relates to a kind of tyre surface exhaust structure of tire-mold.
Background technology
At present, the common tire of tyre industry is all choke with resentment by getting rid of at mould tread design steam vent, avoid because of the various bad orders produced of choking with resentment, exhaust effect is reached in order to make steam vent, the steam vent diameter of design often relatively thick (generally at more than 1.3mm), and be intensively arranged at tyre surface, the hair glue remained in like this on tire finished product can affect outward appearance and serviceability, therefore many operations of removing outshot wool glue post are together needed, its outward appearance adding cost to a certain extent and affect tire finished product.In the prior art for solving the problem, in industry, common practice is, one is by modular form in blocks for tread design, in sulfidation, gas is discharged by the gap between to choke with resentment by sheet mould in mould, do not need specialized designs steam vent again, but which Mould Machining high cost and not easy care, therefore extensively do not adopted; Its two be the diameter design of mould upper air-vent is obtained relatively little, be generally below 0.8mm, less on the impact of tire finished appearance, therefore artificial rejecting is not needed after residual on finished tire hair glue post sulfuration, but because steam vent diameter is less, easy blocking, produces that local is uneven and starved is bad, the requirement of exhaust effect when therefore also cannot meet tire production completely.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of exhaust effect when guaranteeing tire production sulfuration, promotes the tire-mold tyre surface exhaust structure of tire exterior quality further.
For achieving the above object, the utility model is by the following technical solutions:
A kind of tire-mold tyre surface exhaust structure, comprise mold cavity surface, described mold cavity arranges several pattern block die cavities for cured tread pattern block on the surface, described pattern block die cavity is provided with steam vent, and arranges edge exhaust line respectively at the edge of each described pattern block die cavity.
On the edge exhaust line that wherein said steam vent can be arranged at described pattern block die cavity or to be arranged at described pattern block die cavity inner and be connected with the edge exhaust line of described pattern block die cavity by connecting exhaust line.
Described steam vent is divided into lower rank steam vent and upper rank steam vent along described pattern block die cavity to mold outer surface, and the diameter of described lower rank steam vent is less than the diameter of described upper rank steam vent.
As the diameter≤1.5mm of described upper rank steam vent, the ratio of described lower rank steam vent diameter and described upper rank steam vent diameter is 25% ~ 55%;
As the diameter≤3.0mm of rank steam vent on 1.5mm <, the ratio of described lower rank steam vent diameter and described upper rank steam vent diameter is 20% ~ 35%;
As upper rank steam vent diameter > 3.0mm, the ratio of described lower rank steam vent diameter and described upper rank steam vent diameter is 15% ~ 25%.
The degree of depth of described upper rank steam vent is preferably within 3mm.
Described upper rank steam vent can be cylindrical or taper inner convex platform shape.
After adopting technique scheme, the utility model is compared with background technology, and tool has the following advantages:
The utility model makes the gas of tire in sulfidation be discharged to steam vent by the exhaust line of tire-mold tyre surface, make exhaust more abundant, thus strengthen the mobility of tread mix, in appearance, reduce the quantity of hair glue post, enhance aesthetic property to a certain extent, and promote the exterior quality of finished product under hair glue need not be rejected.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
As shown in Figure 1, a kind of tire-mold tyre surface exhaust structure, it comprises mold cavity surface 1, mold cavity surface 1 is arranged several pattern block die cavities 2 for cured tread pattern block, pattern block die cavity 2 is provided with steam vent 3, and edge exhaust line 4 is set respectively at the edge of each pattern block die cavity 2.
Wherein steam vent 3 can be arranged on the edge exhaust line 4 of pattern block die cavity 2, as shown in Figure 1; Also can be arranged at any position of pattern block die cavity 2 inside and be connected with edge exhaust line 4 by connecting exhaust line 5, as shown in Figure 2; Above-mentioned steam vent 3 can arrange one or more on pattern block die cavity 2, and connecting exhaust line 5 can optionally arrange 1 or many, and connection exhaust line 5 can be curve, broken line or straight line.
Steam vent 3 sectional view as shown in Figure 3, steam vent 3 is distributed on pattern block die cavity 2 in two rank designs, and excellent fetch bit in tread block centre of form place, and distributes along tire-mold circumference.Shown in composition graphs 4, described steam vent 3 is divided into lower rank steam vent 32 and upper rank steam vent 31 along pattern block die cavity 2 to mould appearance, and on, lower rank steam vent diameter meets following requirement: as upper rank steam vent 31 diameter D1≤1.5mm, the ratio of lower rank steam vent 32 diameter D2 and upper rank steam vent 31 diameter D1 should meet 25% ~ 55%, when upper rank steam vent 31 diameter D1 meets 1.5 < D1≤3.0mm, the ratio of lower rank steam vent 32 diameter D2 and upper rank steam vent 31 diameter D1 should meet 20% ~ 35%, as upper rank steam vent 31 diameter D1 > 3.0mm, the ratio of lower rank steam vent 32 diameter D2 and upper rank steam vent 31 diameter D1 should meet 15% ~ 25%.By such design, exhaust effect during size and the sulfuration of hair glue post on vulcanised tyre can be guaranteed, promote the exterior quality of finished product when hair glue is not rejected further.Upper rank steam vent 31 can be cylindrical or taper inner convex platform shape, and within the preferred 3mm of degree of depth L1 of upper rank steam vent 31, when degree of depth L1 is too low, fails to reach the effect strengthening exhaust, when degree of depth L1 is too high, easily affect the outward appearance of tire.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
