Molds are the basic process equipment of the manufacturing industry. Without molds, many products cannot be processed normally, because the reprinting of molds can effectively improve production efficiency and reduce production costs. We will find that in the process of processing and making products, the company mainly still has some key parts, and these parts are what we call molds, so the close connection with related industries also makes the mold industry develop very fast in the entire market. quick.
Car interior parts can be made of different materials according to different purposes, but each interior is composed of two parts: fabric and frame. In the manufacturing process, the fabric does not need to be heated, and the skeleton needs to be heated and softened in advance, and then bonded to the fabric and cooled to form. at the same time In order to pursue the elegant temperament of interior parts, the fabric is generally made of light-colored materials, so there can be no stains after molding. In addition, in terms of the shapes of interior parts such as carpets, luggage, box side panels, and wheel covers, the external dimensions are large, and the profiles are free-form surfaces, which are difficult to describe with traditional two-dimensional drawings. . Based on the above characteristics, the traditional mold design and manufacturing process cannot meet the product forming requirements.
1. Mold features According to the characteristics of the above products, the forming mold cannot be made of conventional steel materials. At the same time, the mold material is required to have good thermal conductivity and no rust in addition to basic hardness. In summary, we choose aluminum alloy as the mold material. The molding process refers to the drawing process of the metal cover. The mold does not have a fitting parting surface. An extension surface similar to the pressing ring is left outside the molding part of the mold to fix the fabric. At the same time, the water pipe cooling method is used at the same distance below the molding surface. , to speed up product curing.
2. Before designing the interior parts mold, the 3D data model of the product must be obtained first. According to the current conditions, the data source provided by the customer can be divided into 3D digital model, sample or drawing. The 3D digital model produced by any software can pass IGS. File interface, can be accessed by UG The software reads in to design. If the sample is provided, it is necessary to scan to obtain data points, use reverse engineering technology to construct the product surface, and through continuous comparison and correction, finally obtain the product shape of 3D interior parts. If conditions permit, a one-to-one cavity model can also be processed with polyurethane material. Match physical objects to their counterparts to prevent local defects from having the final impact.
