Um molde é uma ferramenta que usa sua forma particular para dar forma a um produto de uma certa forma e tamanho. Uma variedade de moldes é amplamente utilizada em várias indústrias de processamento de materiais. Por exemplo, a areia ou molde de fundição usado na fundição de metal, matriz de forjamento para processamento de pressão de metal, morrer frio e assim por diante.
O requisito geral do molde é que ele possa produzir produtos públicos que atendam aos requisitos de precisão de dimensão, aparência, physical properties and so on. From the angle of mould use, it requires high efficiency and simple automatic operation, and from the angle of mould manufacture, it requires reasonable structure, easy manufacture and low cost.
The mold affects the quality of the product. Primeiro, the shape, Tamanho, acabamento de superfície, acabamento de superfície, the position of the gate and the exhaust groove and the mode of demoulding, as well as the physical properties of the parts, the mechanical properties, the electrical performance, the internal stress size, the isotropy, the appearance quality, the surface finish, the bubble, e assim por diante. Indentation, scorching, and silvery are very important. Problemas comuns no processo de moldagem por injeção de plástico transparente, in the process of processing, the structure of the mold has a great influence on the operation. In the mass production of plastic products, it is necessary to minimize the opening of the mould, the process of closing the mould and the manual labor in the process of taking the parts. It is also necessary to ensure that the products can be automatically removed from the mold. Além disso, the mold has an impact on the cost of the products. When the batch is not large, the cost of the mold will be very large in the cost of the parts. Nesse momento, a reasonable and simple mold should be used as much as possible to reduce the cost.
In modern production, reasonable processing technology, efficient equipment and advanced mould are three essential factors, especially the mold plays an important role in realizing the requirement of material processing, the application requirement of plastic parts and the modeling design. Efficient automatic equipment can play its role only if the mould can be automatically produced. The production and renewal of the products are based on the manufacturing and updating of the mould. Because of the great demand for product variety and production, the mould is required more and more. Portanto, to promote the continuous development of the mold.
