Mold is a tool that uses its specific shape to form products with a certain shape and size.
In a variety of material processing industry, a wide range of molds are used. For example, sand mold or die casting mold used in metal casting molding, forging mold used in metal pressure processing, cold pressing mold and other molds.
The overall requirements of the mold are: to produce the public ownership products that meet the use requirements in dimensional accuracy, appearance, physical properties and other aspects. From the perspective of mold use, it requires high efficiency and easy automatic operation; from the perspective of mold manufacturing, it requires reasonable structure, easy manufacturing and low cost.
Mold affects the quality of products. First of all, the shape, size, surface finish, parting surface, gate and vent position and demoulding method of the mold cavity have a very important impact on the dimensional accuracy and shape accuracy of the parts, as well as the physical properties, mechanical properties, electrical properties, internal stress, isotropy, apparent quality, surface finish, bubbles, dents, scorch, crazing, etc . Secondly, in the process of metal precision mold processing, the mold structure has a great impact on the degree of difficulty in operation. In the mass production of plastic products, should try to reduce the mold.
The manual labor in the process of closing the mold and taking the parts. Therefore, the automatic opening and closing of the mold and the automatic ejection mechanism are often used. During the full-automatic production, it is also necessary to ensure that the products can fall off from the mold automatically. In addition, the mold also has an impact on the cost of products. When the batch size is small, the cost of the mold will account for a large proportion of the cost of the parts. At this time, we should try to use the mold with reasonable and simple structure to reduce the cost.
In modern production, reasonable processing technology, high-efficiency equipment and advanced mold are three important factors, especially mold plays an important role in realizing the requirements of material processing technology, the use requirements of plastic parts and modeling design. Only when the automatic equipment is equipped with the mould which can produce automatically, can it play its role. The production and renewal of products are based on the manufacture and renewal of mould. Due to the great demand of product variety and output, higher and higher requirements are put forward for the mold. Therefore, promote the continuous development of mold.
The above is the status of mold in the processing industry, I hope to help you, if you want to know more wonderful information, please click our website: Jinan mold http://www.jnhjgs.cn .
