Problems solved by technology

The disadvantage of adopting the design type tire pattern of the prior art solution is that the standardization degree of the mold is low
Secondly, the design efficiency is low
Due to the large and complicated design workload, the efficiency of tire mold design is extremely low, which seriously affects the mold production preparation cycle

Embodiment Construction

[0015] refer to Figure 1-Figure 3 . According to the present invention, on the basis of absorbing the experience of existing tire mold design, the typical and reasonable tire structure is summarized, the shape expression related to the mold tire and the product is simplified, and the quantity, direction, positioning form, etc. Features to classify, draw and build CAD libraries of typical structures of various types of tires. for example figure 2 The typical structural form of the molded tire with single-flange open angle and hole positioning shown. The profile of the upper and lower mold tires, the profile is flat or curved surface with small curvature, single curved edge, all are right angles or open angles, and no non-working sharp edges are rounded R, the size is determined according to the template, mold body 2, cover The corresponding profile of the plate 3, belt depression, curved surface features, detailed expression features such as the graphics, position, and tol...

Abstract

The invention provides a rapid design method of a tyre mould, which comprises the following steps of: 1) simplifying the expressed mould design pattern, classifying the shape related characteristics of the tyre mould, and drawing and establishing a CAD (computer-aided design) pattern library of the typical structure of various types of tyres; 2) compiling a special tyre designing and manufacturing specification, attaching tyre typical structure legends corresponding to the tyre typical structure pattern library and the pattern of the simplified drawing work order, and classifying and numbering the typical structure legends; and 3) correspondingly selecting a legend number from the typical structure specification according to the product shape, calling the CAD pattern from the typical structure pattern library and filling the CAD pattern into the simplified drawing work order according to the number, and finally filling an order number, a fixture pattern number and other simple information into the work order to finish the design. As the tyre typical structures in the invention are strictly classified, the classes nearly include all tyre structure types and the compiling idea is novel, the tyre mould is convenient and quick to use by designers, the design speed is increased by 6-10 times than that before, and the manual labor and material resources are saved. The invention can greatly shorten the production preparation period, and provides solid technical storage for the development of new products.

Description

technical field [0001] The invention relates to a rapid design method for a tire mold. Background technique [0002] The tire is one of the main tools for forming sheet metal parts. It is usually used for bending forming, surface forming, sinking forming of sheet metal parts, and forming or correcting special shapes such as flanging holes and ribs. The cutting line of the product is engraved on the mold to check the cutting shape of the product. The main parts of the mold are composed of one or more mold bodies, cover plates, positioning pins, positioning plates and other parts. When designing tires, it is necessary to strictly follow the relevant design specifications and procedures to draw the detailed shapes of the product such as cutting lines, sags, ribs, and flange holes, otherwise it will lead to a high repair rate. The prior art type tire design is extremely low in standardization because there is no detailed simplified design specification. The existing technical...
