Abstract
The utility model discloses a kind of run-in index spew groove die panel, including upper die panel and lower die panel, upper die panel is provided with groove, and spew groove is provided with lower die panel, and spew groove is corresponded with groove bottom.The utility model processing method is simple, practical, convenient, and application prospect is good；Can effectively solve the problem that extruded tread bottom is prolonged groove direction and obvious groove mark occurs, tyre surface qualification rate is obviously improved；Eliminate the groove mark of tyre surface bottom appearance, it is to avoid air and tire are sheltered below tyre surface and occurs shoulder sky in use（It is de-）Hidden danger.
Description
Technical field
The utility model is related to a kind of die panel, relates in particular to a kind of run-in index spew groove die panel.
Background technology
It is exactly that, in extruded tread, groove side is prolonged in tyre surface bottom that a kind of product quality defect often occurs in tyre industry
To obvious groove mark occurs, cause finished product tire tread groove bottom to shelter air, cause finished product tire tread that gas appear below
Bubble, and it is empty that tire can be caused to occur shoulder when in use（It is de-）Phenomenon.As depicted in figs. 1 and 2, at present, tyre surface extrusion when, mouth
Opening section product in groove bottom is relatively small on template, and shape of the mouth as one speaks face pressure is big at this, and by die panel, open tip sets in itself
The influence of meter, causes tyre surface bottom to prolong groove direction and obvious groove mark occurs, causes finished product tire tread groove bottom nest
Air is hidden, causes finished product tire tread that bubble appear below, and it is empty that tire can be caused to occur shoulder when in use（It is de-）Phenomenon.
The content of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, there is provided a kind of run-in index gummosis slot type
Plate.
To achieve the above object, the utility model uses following technical scheme：Run-in index spew groove die panel, including it is suitable for reading
Template and lower die panel, upper die panel are provided with groove, and spew groove is provided with lower die panel, and spew groove is with groove bottom one by one
Correspondence.
The open height H that the groove bottom has drop, spew groove between two adjacent decorative pattern tops respectively is equal to two
Minimum drop in individual drop.
The shape of the spew groove is parallel with groove open form face, and spew groove bottom land is seamlessly transitted.
Thickness of the opening depth S of the spew groove less than lower die panel.
The utility model processing method is simple, practical, convenient, and application prospect is good；Can effectively solve the problem that extruded tread bottom
Prolong groove direction and obvious groove mark occur, tyre surface qualification rate is obviously improved；Eliminate the groove mark of tyre surface bottom appearance, it is to avoid tyre surface
Air and tire are sheltered below occurs shoulder sky in use（It is de-）Hidden danger.
Brief description of the drawings
Fig. 1 is prior art construction schematic diagram.
Fig. 2 is the tyre surface defect map that prior art is caused.
Fig. 3 is the utility model structural representation.
Fig. 4 is extruded tread schematic diagram of the present utility model.
Fig. 5 is the utility model implementation process schematic diagram 1.
Fig. 6 is the utility model implementation process schematic diagram 2.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Run-in index spew groove die panel as shown in Figure 3, including upper die panel 1 and lower die panel 4, set on upper die panel 1
Have groove 2, be provided with spew groove 3 on lower die panel, spew groove 3 is corresponded with groove bottom, groove bottom respectively with it is adjacent
Two decorative pattern tops between have a drop, the open height H of spew groove 3 is equal to minimum drop in two drops, the shape of spew groove 3
Shape is parallel with groove open form face, and spew groove bottom land is seamlessly transitted, so as to eliminate die panel open tip effect, it is ensured that tip position
The sizing material pressure balance put, so as in the gummosis amount of the pressure of reduction die panel open tip position, increase groove bottom
Meanwhile, opening section is accumulated the sizing material flowing that relatively small tread groove bottom obtains balance, as shown in Figure 4, it is ensured that tyre surface
Bottom is smooth；Thickness of the opening depth S of spew groove 3 less than lower die panel 4, it is ensured that the spew groove 3 opened cannot extend into the shape of the mouth as one speaks
On the non-working surface of plate.
Embodiment
As shown in figure 5, spew groove 3 is opened on lower die panel 4, spew groove 3 is corresponded with groove bottom, first decorative pattern
Bottom of trench is more than the drop h1 with the right decorative pattern top with the drop on left side decorative pattern top, then the open height of spew groove 3 is h1, so as to
Enough determine a points position, the parallel lines parallel to groove open form line AB and AC are done as starting point, respectively with a points, the lower shape of the mouth as one speaks is handed over respectively
In point b and point c, connecting line ab and ac, then line ab and line ac is two aperture lines of spew groove 3 to plane on plate 4, so that it is determined that stream
The A/F of glue groove 3；As shown in fig. 6, the online circular arc boc that rounding off is done between ab and line ac, so that it is determined that spew groove 3
First opening shape, and the opening depth of spew groove 3 less than lower die panel 4 thickness, it is ensured that the spew groove 3 opened can not prolong
Reach on the non-working surface of die panel；The like, it may be determined that the opening size and shape of other spew grooves 3.
Claims (4)
