Description

[Technical field]

[0001] The utility model relates to the technical field of jewelry processing, in particular to a combined oblique insertion punching die for die-casting jewelry. [Background technology]

[0002] 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.

[0003] 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.

[0004] At present, some precious metal jewelry products that are generally in the form of sheets are also 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. However, some products have a trapezoidal shape or a concave structure in the middle. If only the upper and lower molds are combined, there is a problem of not being able to demold smoothly. Therefore, for products with different shapes, it is necessary to design molds with left and right demolding combined with upper and lower demolding. [Summary of the invention]

[0005] In view of the above problems, the utility model proposes a combined oblique insertion stamping die, which comprises an upper die and a lower die, and is characterized in that it also comprises a front die and a rear die which are laterally closed, a positioning guide column and a compression spring are provided between the front die and the rear die, and a push block with an oblique insertion wedge surface is provided between the upper and lower dies and outside the front and rear dies; the front die and the rear die are inserted into the limiting groove of the lower die, a compression spring is inserted between the front die and the rear die, so that there is a gap between the front die and the rear die, and two push blocks are provided on the upper die, and the gap between the push blocks is equal to the thickness of the front die and the rear die.

[0006] A guide slide post and a guide slide hole are provided between the lower die and the upper die. The guide slide post is inserted into the guide slide hole to guide the upper die and the lower die.

[0007] A product mold cavity is provided on the contact surface of the front mold and the rear mold. The front mold is provided with a first mold cavity groove, and the rear mold is provided with a second mold cavity groove. The first mold cavity groove and the second mold cavity groove are combined to form a whole product mold cavity.

[0008] A positioning guide column and a guide sliding hole are provided between the front mold and the rear mold, and the positioning guide column is inserted into the guide sliding hole to guide the front mold and the rear mold.

[0009] A spring groove is arranged between the front mold and the rear mold, and a compression spring is arranged in the spring groove.

[0010] The push block has two pieces, namely a first push block and a second push block. The first push block is inserted downward into a first push groove set on the lower mold and outside the front mold, while the second push block is inserted downward into a second push groove also set on the lower mold and outside the rear mold.

[0011] The lower ends of the first push block and the second push block have a guide sliding angle on one side facing the front mold and the rear mold.
