Description

For manufacturing the basic mode of tire mould pattern block

Technical field

It the utility model is related to tire-mold manufacturing field, and in particular to for manufacturing the basic mode of tire mould pattern block.

Background technology

Tyre adjustable die is the mould of last sulfidization molding in radial tyre production.The main knot of activating mold Structure includes housing and die cavity two large divisions.Housing is the external structure of tire-mold also known as to concentric mechanism, plays connection vulcanization The effect of machine and internal die cavity；Die cavity is the internal structure of mould, is the die cavity with green tyre shaping.Housing parts have external mold Set, guiding mechanism, arcuate seat, upper lid and base；Die cavity includes pattern block, upper and lower side form and upper and lower steel ring etc..In die cavity Pattern block is the direct pith for forming tire top decorative pattern after tyre vulcanization.

Usual split blade type tread pattern mold is spliced to enclose successively by eight decorative pattern module units to be formed.Decorative pattern module unit (is called in the following text Pattern block) manufacturing process comprises the following steps：1st, basic mode is fabricated to arc section, and carved out on the arcwall face of basic mode some The pattern forming face of individual pitch composition, then makes the shim consistent with pattern pitch axial direction curve；2nd, basic mode is put into silicon Inside glue box, then to the silica gel that injection has reconciled between silica gel liner mold inwall and basic mode periphery；3rd, silica gel liner plate is treated After silica gel solidification in mould, silica gel liner mold is opened, the Silicon moulds of shaping are disassembled from basic mode surface stand-by；4th, to Pouring gypsum inside Silicon moulds, form gypsum core；5th, shim is inserted in gypsum core and is dried；6th, aluminium liquid is poured into gypsum core In mould cavity, it is molded using gravitational casting；7th, the decorative pattern module of shaping is detected, the process such as milling car, drilling and tapping, pincers are repaiied After obtain final pattern block product.

At present, the overall structure that basic mode is used when producing pattern block is similar to arc section, and middle part is raised arcwall face (flower Line forming surface).Because basic mode needs to ensure possess enough intensity, its edge ensures certain thickness, matches somebody with somebody again with silica gel box Close, so being currently that the pattern forming face 2 of basic mode 1 is extended into one section of transition face 3 towards both sides cambered surface, as shown in Figure 3.This must So cause the gross thickness of basic mode to increase, increase production cost.

The content of the invention

The purpose of this utility model is to provide a kind of low basic mode for being used to manufacture tire mould pattern block of production cost.

To achieve the above object, present invention employs following technical scheme：A kind of base for being used to manufacture tire mould pattern block Mould, including base and carved out on the middle of the base and convex segmental arc, the arcwall face of the segmental arc decorative pattern composition Pattern forming face, segmental arc form transition face towards the extension of two side planes.

Due to using above technical scheme, in pattern forming face, both-side ends extend the transition face of plane, are the equal of Basic mode both ends are upturned, and reduce the integral thickness of basic mode while intensity requirement is met, significantly cost-effective.

Embodiment

A kind of basic mode for being used to manufacture tire mould pattern block, basic mode 10 include base 14 and positioned at the middle parts of base 14 and in convex The segmental arc 11 of shape is played, decorative pattern is carved out on the arcwall face of the segmental arc 11 and forms pattern forming face 12, segmental arc 11 towards two Side plane extension forms transition face 13.The shape and structure of segmental arc 11 are corresponding with pattern block, similar to eighth wheel Tire, decorative pattern corresponding with tire is carved out on the arcwall face of segmental arc 11.At the both ends of segmental arc 11 respectively to two side planes Extension forms transition face 13.Length direction extension of the both ends of segmental arc 11 along base 14 is alternatively crossed, transition face 13 Specific length dimension is depending on matched silica gel box size.It is described in detail with reference to accompanying drawing 2 and 3, in segmental arc 11 Radius it is identical, in the case of the length dimension identical of base, plane extends the edge of pedestal 10 in this scheme of transition face Thickness is naturally larger than the thickness that the arcwall face of segmental arc 11 of postponing extends this scheme of transition face.For example, pedestal 10 is overall When thickness is 110mm, susceptor edges thickness is more than 8mm in the application, it is possible to meets intensity requirement.And use first with existing skill During scheme in art, it is necessary to the integral thickness of pedestal is increased into 120mm, its edge thickness could meet to require.It is possible thereby to Find out, the transition face 13 of the application midplane shape can save great amount of cost, and it is left that applicant can save material cost 300,000 for 1 year The right side, and reduce operation load and the process time of five-axis robot middle and high end equipment, generate obviously economic well-being of workers and staff.

It is round-corner transition between described pattern forming face 11 and transition face 12.Knuckle between two faces is usually R10-R100, it is not only convenient for processing using round-corner transition between two faces, and is also convenient for being stripped.

The edge thickness of described basic mode 10 is more than 8mm.As shown in Fig. 2 in figure L meanings band be basic mode 10 edge Thickness, as long as ensureing that the thickness is more than 8mm, the intensity of basic mode 10 just disclosure satisfy that requirement.
