Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1
Fig. 1 is the expanded view with M, L and tri-pitch tyre treads of S. The group chip tire corresponding with this tyre tread is activeThe manufacture method of mould pattern ring comprises the following steps:
The first step, considers that tyre tread shape, steel disc are arranged, pitch arrangement mode and the factor such as exhaust is smooth and easy, at tireIn the expanded view of decorative pattern, mark off tri-kinds of decorative pattern unit of A, B and C. Each in whole pattern ring according to A, B and tri-kinds of unit of CFrom quantity, mix into two kinds of decorative pattern unit combination as shown in Figures 2 and 3, undertaken by these two kinds of decorative pattern unit combinationManufacture, each decorative pattern leaves allowance between unit.
In the time that the expanded view of tyre tread is divided, consider following factor:
(1) position of steel disc: the position that will hide steel disc in the time that the expanded view of tyre tread is divided, ensures dividing line notCan cut tablet;
(2) exhaust facility: find the place of easily choking with resentment of pattern ring, in the place's cutting of easily choking with resentment, at the place of easily choking with resentment, dividing line is set;
(3) pitch arrangement mode;
(4) tyre tread shape: arranging of dividing line is mainly to determine according to tyre tread shape, will consider above three simultaneouslyThe factor of kind, then divides.
In actual production process, mark off behind several decorative pattern unit the decorative pattern unit group of its collocation composition according to above factorIt as unification, is one to three kind.
Second step, is carved in respectively Dai Mu two kinds of decorative pattern unit combination that match upper, between each unit, leaves allowance,As shown in Figures 2 and 3. Due to the two kinds of decorative pattern unit combination of having arranged in pairs or groups out in step 1, therefore according to two kinds of decorative pattern unit combination,In two kinds of generations of carve, are wooden.
The 3rd step, with two kinds shown in Fig. 2 and Fig. 3, for carpentery workshop basis mould, hot investment casting goes out the aluminium alloy shown in Fig. 4 and Fig. 5Decorative pattern embryo. The process of its hot investment casting is as described below:
First be, the molded silica gel mould of doing in basis with two kinds shown in Fig. 2 and Fig. 3 for carpentery workshop; Then, utilize the molded stone of doing of silica gelCream mould; Finally, with the aluminium alloy casting plaster mold of melting, can obtain aluminum alloy pattern embryo, the decorative pattern shape of aluminum alloy pattern embryoWooden identical with generation.
In actual manufacture process, generally need to according to two kinds generation wooden hot investment casting polylith aluminum alloy pattern embryo.
The 4th step, cuts the each unit in above-mentioned aluminum alloy pattern embryo and finish-milling processing, obtains polylith decorative pattern element entity.
The 5th step, fixes above-mentioned decorative pattern element entity according to the relative position in Fig. 1, be combined into several pattern blocks, as figureShown in 6, be provided with the gap of 0.02mm-0.03mm between each decorative pattern element entity, this gap is for sulfidation mouldExhaust. A complete pattern ring of above-mentioned several pattern block compositions. According to the difference of tire specification, the pattern ring shown in Fig. 7Generally formed by eight to ten pattern blocks.
A complete pattern ring is made up of 8 to 10 pattern blocks, and wherein all wire tyre activating mold is generally 9 or 10Piece, half wire will tyre adjustable die is generally 8.
In the present invention, described Dai Mu also can be replaced by the identical other materials of function. Therefore, even selected engravingMaterial difference, can realize identical function, among the protection domain all requiring in the present invention. The above-mentioned explanation of this paragragh is sameSample is also applicable to other embodiment of the present invention, illustrates in the lump, no longer repeatedly narration at this.
Embodiment 2
Fig. 8 is the expanded view of only having a pitch L tyre tread, considers tyre tread shape, steel disc layout, pitch rowThe factors such as row mode and exhaust are smooth and easy mark off two kinds of decorative pattern unit of A and B in the expanded view of tyre tread. According to A and BTwo kinds of unit quantity separately in whole pattern ring, mixes into a kind of decorative pattern unit combination and manufactures, and this flowerIt is upper that line unit combination is carved in Dai Mu, between each unit, leaves allowance, as shown in Figure 9, in this embodiment, only needs carvingCarve a kind of generation wooden. With as shown in Figure 9 for carpentery workshop basis mould, hot investment casting goes out the aluminum alloy pattern embryo shown in Figure 10.Each unit in above-mentioned aluminum alloy pattern embryo is cut and finish-milling processing, obtain polylith decorative pattern element entity, by polylith decorative patternElement entity is combined into the pattern block shown in Figure 11 according to the relative position in Fig. 8, between each decorative pattern element entity, is provided withThe gap of 0.02mm-0.03mm. A complete pattern ring of above-mentioned several pattern block compositions.
Other are with embodiment 1.
Embodiment 3
Figure 12 is with the expanded view of L, M, S and tetra-pitch tyre treads of W, considers tyre tread shape, steel disc clothPut, pitch arrangement mode and the factor such as exhaust is smooth and easy, in the expanded view of tyre tread, mark off A, B, C and tetra-kinds of decorative patterns of DUnit. According to A, B, C and tetra-kinds of unit of D quantity separately in whole pattern ring, mix into a kind of decorative pattern unit groupClose and manufacture, and it is upper that this decorative pattern unit combination is carved in to Dai Mu, between each unit, leaves allowance, as shown in figure 13,I.e. this embodiment carve wood of a kind of generation. With as shown in figure 13 for carpentery workshop basis mould, hot investment casting goes out shown in Figure 14Aluminum alloy pattern embryo. Each unit in above-mentioned aluminum alloy pattern embryo is cut and finish-milling processing, obtain polylith decorative pattern unit realBody, is combined into the pattern block shown in Figure 15 by polylith decorative pattern element entity according to the relative position in Figure 12, and each decorative pattern unit is realBetween body, be provided with the gap of 0.02mm-0.03mm. A complete pattern ring of above-mentioned several pattern block compositions.
