Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0030] In order to make the connection between the additively manufactured body and the machined matrix more interchangeable, an intermediate connecting body is added as a transition part in the specific implementation. The tire mold shown in this embodiment is specifically divided into three parts, which are an additively manufactured body 1, an intermediate connecting body 2 and a machined base body 3. The additively manufactured body 1, the intermediate connecting body 2 and the machined base body are connected by mechanical connection. 3 Assemble a complete set of molds, the mechanical connection is bolt or screw connection, and will be assembled into a single complete mold, such as figure 1 shown.
[0031] The structural design form of the additively manufactured body 1 in this embodiment is as follows figure 2 shown. Print c...

The invention discloses a reusable tire mold manufacturing method based on additive manufacturing technology. A single tire mold is processed in blocks. The single tire mold is divided into an additive manufacturing body and a machining base. The additive manufacturing body is passed through The additive manufacturing process is processed, and the machined substrate is processed by the traditional manufacturing process, and the two are combined through a mechanical connection, and finally the tire is formed. Driven by 3D drawing software, metal powder is melted layer by layer or fed in synchronously to produce additive manufacturing objects with complex patterns. The original additive manufacturing body is separated from the machining base; then the new additive manufacturing body is connected to the original machining base and assembled into a single overall mold, and then assembled into a complete mold. The production link of the present invention is more efficient, and is more energy-saving and environment-friendly compared with traditional processing methods; at the same time, vulcanization of tires with different patterns is more convenient and fast, and the machined substrate can be reused, which saves production and manufacturing costs.
Description
technical field [0001] The invention relates to a novel tire mold manufacturing method, in particular to a tire mold manufacturing method combining an additive manufacturing body and a reusable substrate through a detachable mechanism, belonging to the field of advanced manufacturing. Background technique [0002] Molds are widely used in various fields of the national economy. Throughout the history of the development of molds, from the initial hand-made, to mechanical processing, to the digital design and CNC machining of automatic control molds that are commonly used today, the precision and complexity of the molds are getting higher and higher, and the cost and production cycle are gradually increasing. reduce. With the rapid development of my country's automobile industry, the manufacturing level of tire molds and tires has also made great progress. The rapid upgrading of the automobile tire industry has stimulated the continuous growth of the tire mold market. The ti...
