In the process of actual processing and manufacturing of Chair Mould, there are more technological achievements transformed here, and it is also an important development field of the high-tech industry. Many people think that in the process of actual development, a steady stream of power can be injected into society. How should the chair mould be designed in the process of selection or design?
1. mould opening direction
In the process of processing the chair mould, each product must determine the mould opening direction before starting to set up. This way, the irregular situation of all products can be reduced as much as possible and the influence of the products on the appearance can also be eliminated. After the mould opening direction is determined, the structures of the products in various places can be ensured to be consistent in design as much as possible, and the structures in the buckles or bulges of the products can be ensured. The consistency with the mould opening direction must be guaranteed to avoid the reduction of splicing seams, and the service life of the mould must be effectively prolonged. After the mould opening direction is determined, an appropriate parting line can be selected to avoid the phenomenon of reverse buckling in the mould opening direction.
2. Demoulding slope
During the actual processing and production of the chair mould, the inclination of the demoulding can effectively prevent the product from having the inclination of a roughened and smooth surface, usually more than 0.5 degrees, and the fine surface is more than 1 degree, and the surface of the whole rough leather grain is usually more than 1.5 degrees. Appropriate assistance can effectively prevent various top injuries of the product, such as white top or deformation of the top. In addition, if the slope of the whole structural product can be well done during the design process, then they will basically be larger than the slope of the inner surface. In this way, the mould will not shift during injection moulding, the whole product can obtain uniform thickness, and the material strength of the opening position of the product can be ensured.
3. Product wall thickness
During the overall processing and design of the chair mould, all kinds of plastics must ensure the thickness of the product wall uniformly. Generally speaking, their thickness is controlled between 0.5 mm and 4 mm. When the wall thickness of the whole product exceeds 4 mm, the cooling time will be relatively long. The whole product may have a shrinkage problem. Moreover, the original structure of the product must be taken into account. The thickness of the whole product will not cause surface shrinkage, and they will not cause air holes or welding marks.
When designing the chair mould, the design of the reinforcing ribs must be reasonable, the rigidity of the whole product must be effectively enhanced, and the deformation must be rapidly reduced in a short time, because the thickness of the reinforcing ribs must be ensured to be between 0.5 and 0.7, otherwise the surface may shrink, and the unit area of the reinforcing ribs must be greater than 1.5 degrees to avoid the top injury.
