Форма - гэта інструмент, які выкарыстоўвае сваю асаблівую форму для фарміравання прадукту пэўнай формы і памеру. Разнастайнасць прэс-формаў шырока выкарыстоўваецца ў розных галінах апрацоўкі матэрыялаў. Напрыклад, пясок або форма для ліцця пад ціскам, якая выкарыстоўваецца для ліцця металу, кавальскі штамп для апрацоўкі металу ціскам, халодная памерці і гэтак далей.
Агульнае патрабаванне да прэс-формы заключаецца ў тым, што яна можа вырабляць прадукцыю агульнага карыстання, якая адпавядае патрабаванням дакладнасці памераў, знешні выгляд, 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. Па -першае, the shape, памер, аздабленне паверхні, аздабленне паверхні, 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, і гэтак далей. Indentation, пякучы, and silvery are very important. Па-другое, у працэсе апрацоўкі, 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. У дадатак, 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. У гэты час, 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. Таму, to promote the continuous development of the mold.
