Abstract
Description
[Technical field]
[0002] The utility model relates to the technical field of jewelry processing, in particular to a stamping die device used for die-casting metal jewelry. [Background technology]
[0004] In the traditional precious metal jewelry processing industry, the most traditional processing method is usually metal smelting. Clean water is first melted manually through high-temperature smelting, and then the mold with the shape to be cast is heated. The molten metal liquid is poured into the mold while it is hot. After cooling and forming, it is taken out to obtain the molded jewelry. A certain degree of polishing may be required later to obtain the best appearance of the jewelry product.
[0005] If the jewelry is three-dimensional, the biggest problem with casting is demoulding. Some products are made of closed molds made of gypsum, with only a tiny pouring port. After cooling and molding, the mold is destroyed to obtain the molded product. This method is rarely used now. The process is simple and the finished product is rough and does not meet the aesthetic taste of consumers. In addition, the process is cumbersome and demoulding is difficult. It is highly dependent on manual labor, which is inefficient and does not meet the economic benefits.
[0006] Nowadays, some precious metal jewelry products that are generally in the form of sheets are die-casted using molds. Generally, the upper mold and the lower mold are combined to squeeze the internal liquid metal to fill the interior of the mold. After cooling and shaping, the mold is opened to obtain the molded product. When the upper and lower molds are combined to extrude, there will be a large lateral force. If the mold is not laterally constrained and controlled, displacement will occur, causing deformation. Therefore, it is necessary to design an anti-lateral displacement component between the upper and lower molds to control deformation. [Summary of the invention]
[0008] The utility model proposes a stamping die to prevent lateral displacement in view of the above problems. The stamping die is specially designed with a wedge-shaped positioning block for limiting the lateral movement of the upper die and the lower die. The wedge-shaped positioning block is installed between the upper die and the lower die to improve the displacement of the die and improve product quality.
[0009] The utility model relates to an anti-lateral displacement stamping die, comprising an upper die base, a lower die base and a guide slide column, and is characterized in that a wedge-shaped positioning block is provided between the lower die base and the upper die base, the wedge-shaped positioning block is embedded in the upper die base, and its wedge-shaped head end extends out of the upper die base, and a wedge-shaped groove is provided on the mold closing surface of the lower die base corresponding to the wedge-shaped positioning block, and the wedge-shaped positioning block is inserted into the wedge-shaped groove with its wedge-shaped head end positioned when the mold is closed.
[0010] There are 1 to 4 wedge-shaped positioning blocks, which are evenly distributed on the upper die seat.
[0011] A product forming groove is provided between the mating surfaces of the upper die seat and the lower die seat. The product forming groove is divided into an upper groove and a lower groove. The upper groove is arranged on the upper die seat, and the lower groove is arranged on the lower die seat. The upper groove and the lower groove are butted together to form an integral product forming groove.
[0012] A fixed guide slide column is arranged on the upper die seat / lower die seat, one end of the guide slide column is fixedly arranged in the upper die seat / lower die seat, and the other end faces the guide slide column hole of another butted die seat.
[0013] There are 2 to 5 guide slide columns, which are evenly distributed around the product forming groove on the upper die base / lower die base.
[0014] The utility model relates to a stamping die for preventing lateral displacement, which has a wedge-shaped positioning block for limiting lateral displacement, and a wedge-shaped structure with an inclined surface is inserted into a wedge-shaped groove, thereby strictly limiting lateral looseness and displacement, avoiding deformation during product processing, and improving product quality.
