Description

Shaper before a kind of tyre tube vulcanizer

Technical field

The utility model relates to inner tube of a tyre manufacturing equipments, and in particular to shaper before a kind of tyre tube vulcanizer.

Background technique

The inner tube of a tyre is the important component of tire, and the tube production process process now generallyd use is as follows: fetus squeezes out, fixed Lengthening joint, inflates pre-setting, vulcanization, and inflation is examined.Pre-setting before tyre tube vulcanizer is put into stock mould after needing fetus to fold It is interior, stock mould is closed, compressed air is filled in fetus from from valve cock, until fetus is expanded into stock mould size, is then cut It dies source.After being kept for a period of time, it is fitted into vulcanizer and is vulcanized.Stock mould has half formula, clamshell, two halves formula.Stock mould Size directly affects inner tube finished product quality.Stock mould is undersized to be easy to cause finished product became uneven, excessive to be easy to cause finished product Press it is residual scrap, final product quality is not easy to control, very high to operative employee's skill requirement, and labor efficiency is low.

Utility model content

The utility model, which is put forth effort on, solves above-mentioned existing deficiencies in the technology, and it is fixed before a kind of tyre tube vulcanizer to provide Pattern tool, according to tyre tube vulcanizer die size, determines the specific size of stock mould.Due to given method for determining size, so Solve the problems, such as that tyre tube vulcanizer stock mould size can not determine, mainly for two halves formula stock mould.

It is as follows that the utility model solves technical solution used by above technical problem: stock mould before a kind of tyre tube vulcanizer Tool, it is characterised in that: stock mould section is ellipse, profile height H_MouldLess than section width W_Mould, stock mould mold core height is greater than Inner tube mold mold core height.

Further, the profile height H of the stock mould_MouldFor inner tube of a tyre cross section diameter D_{It is disconnected}0.94~0.96 times.

Further, the section width W of the stock mould_MouldEqual to inner tube of a tyre cross section diameter D_{It is disconnected}?.

Further, the inner tube of a tyre cross section diameter D_{It is disconnected}With inner tube of a tyre interior diameter D_{It is interior}Ratio it is bigger, the profile height of stock mould H_MouldValue it is bigger.

Further, the interior diameter D of the stock mould_{In mould}For inner tube of a tyre interior diameter D_{It is interior}1.01~1.05 times.

Further, the overall diameter D of the stock mould_{Outside mould}For inner tube of a tyre overall diameter D_Outside1.01~1.05 times.

Further, the inner tube of a tyre cross section diameter D_{It is disconnected}With the inside and outside diameter D of the inner tube of a tyre_{It is interior}、D_OutsideRatio it is bigger, the stock mould Inside and outside diameter D_{In mould}, D_{Outside mould}Corresponding value is bigger.

Compared with prior art, the stock mould of the utility model can make up the inner tube of a tyre and produce after being put into inner tube mold vulcanization Raw deformation, yield rate are under control.

Detailed description of the invention

Attached drawing is only used for showing the purpose of specific embodiment, and is not considered as limitations of the present invention, entire In attached drawing, identical reference symbol indicates identical component.

Fig. 1 is standard inner tube of a tyre shape graph；

Fig. 2 is deformation inner tube of a tyre shape graph；

Fig. 3 is stock mould shape graph provided by the utility model.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples, wherein attached drawing constitutes the application one Part, and be used to illustrate the utility model together with the embodiments of the present invention.But it will be appreciated by those skilled in the art that Following embodiment is not the unique restriction made to technical solutions of the utility model, all in technical solutions of the utility model spirit The lower any equivalents or change done of essence, are regarded as belonging to the protection scope of the utility model.

Finished product inner tube of a tyre reference dimension mainly has interior diameter D_{It is interior}, overall diameter D_Outside, cross section diameter D_{It is disconnected}With thickness C, most of inner tube of a tyre It is the circular ring type of standard, as shown in Figure 1.For a small number of inner tubes of a tyre due to cover tire flattening, section configuration is the annulus of ellipse, is such as schemed Shown in 2, therefore section cannot be only with cross section diameter D_{It is disconnected}It indicates, but is indicated by fetus profile height H and section width W, height Size is greater than width dimensions.

Inner tube finished product size decides inner tube mold size, under normal circumstances inner tube mold inner profile curve and inner tube of a tyre foreign steamer Wide curve is consistent, and size is consistent (not considering to vulcanize shrinking percentage).

Stock mould Internal periphery data directly determine shape and size after the sizing of inner tube of a tyre fetus.Fetus after sizing is put into the inner tube of a tyre In mold, interior diameter should be more bigger than mold interior diameter, and overall diameter is more smaller than mold overall diameter.From fixed after the completion of fetus sizing After taking out in pattern, due to the flexible deformation of sizing material, fetus is possible to that Fig. 2 shape can be shrunk to.

To overcome deformation, the utility model uses reverse engineer mode, stock mould is made into and Fig. 2 inner tube of a tyre deformed shape phase Anti- shape, as shown in figure 3, section is ellipse, profile height H_MouldLess than section width W_Mould(having flattening ratio), stock mould mold core Height H_{Mold core}Greater than inner tube mold mold core height (" mold core height " refers to that half module exceeds the height of mold center's line).

It is summarized by constantly testing production, obtains the relationship of stock mould the size of each part and inner tube of a tyre the size of each part such as Under:

1) stock mould interior diameter D_{In mould}

D_{In mould}=D_{It is interior}* (1.01~1.05)

D_{It is interior}For inner tube of a tyre interior diameter.Inner tube of a tyre cross section diameter D_{It is disconnected}With interior diameter D_{It is interior}Ratio is bigger, D_{In mould}Value it is bigger.

2) stock mould overall diameter D_{Outside mould}

D_{Outside mould}=D_Outside* (1.01~1.05)

D_OutsideFor inner tube of a tyre overall diameter.Similarly, inner tube of a tyre cross section diameter D_{It is disconnected}With overall diameter D_OutsideRatio is bigger, D_{Outside mould}Value it is bigger.

3) stock mould section width W_Mould

W_Mould=D_{It is disconnected}。

4) stock mould profile height H_Mould

H_Mould=D_{It is disconnected}* (0.94~0.96)

Inner tube of a tyre cross section diameter D_{It is disconnected}With interior diameter D_{It is interior}Ratio is bigger, profile height H_MouldValue it is bigger.

Above-mentioned design is all suitable for the normal inner tube of a tyre or the flattening inner tube of a tyre, and only flattening inner tube of a tyre value is generally according to small Value takes.

Stock mould mold core height H_{Mold core}It should be greater than inner tube mold mold core height.In general, stock mould mold core height is the inner tube of a tyre 1.1-1.2 times of mould core height, inner tube of a tyre cross section diameter D_{It is disconnected}Bigger, stock mould mold core height value is bigger.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
