[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In one embodiment, a manual jewelry mold integrating stamping and punching is provided, such as... Figures 1-2As shown, the manual jewelry mold integrating stamping and punching includes an upper mold 11, a punch 12, and a lower mold 13. The upper mold 11, punch 12, and lower mold 13 are all made of metal, such as stainless steel. An insertion hole 111 for inserting jewelry blanks is provided on the front side of the upper mold 11. The shape and size of the insertion hole 111 are set according to the jewelry blank. A punch hole 112 intersects the insertion hole 111 in the upper mold 11. The shape and size of the punch hole 112 are set according to the jewelry to be processed. The punch 12 is used to insert the punch hole 112 to punch the jewelry blank to form a jewelry blank. Since the punch hole 112 intersects the insertion hole 111, the jewelry blank inserted from the insertion hole 111 is blocked in the punch hole 112. In this way, the punch 12 can punch the jewelry blank from the punch hole 112.

[0019] The lower die 13 has a molding groove 131 on its top surface that matches the jewelry blank, and the upper die has a corresponding molding protrusion 113 on its bottom surface. The jewelry blank formed by punching is placed in the molding groove 131, and the molding protrusion 113 is used to press the jewelry blank in the molding groove 131 to obtain a semi-finished jewelry product. The sum of the thickness of the jewelry blank and the thickness of the molding protrusion 113 is slightly greater than the depth of the molding groove 131, so that when the jewelry blank in the molding groove 131 is punched by the molding protrusion 113, the jewelry blank can be squeezed. At the same time, during the extrusion process, the bottom surface of the upper die 12 can be supported on the top surface of the lower die 13 to prevent the molding protrusion 113 from tilting in the molding groove 131, and to ensure that the thickness of the stamped semi-finished jewelry product is consistent and does not deform.

[0020] This manual jewelry mold that integrates stamping and die cutting is specially designed to combine the molds required for two different jewelry cutting and stamping processes into one set of molds, thereby reducing mold costs. Furthermore, due to the reduction in the number of molds, the molds used to process different jewelry are easy to distinguish from each other, making it easier to store the molds and less likely to get confused, which helps to improve the processing efficiency of different jewelry.

[0021] Combination Figure 3As shown, the manual jewelry mold integrating stamping and punching is used as follows: The lower mold 13 is placed on the support table, and the upper mold 11 is stably placed on the lower mold 13. The jewelry blank A is inserted into the insertion hole 111 of the upper mold 11. The jewelry blank A is a pre-made raw material for jewelry processing; here, the jewelry blank A is a gold bar blank. Then, the jewelry blank A is punched through the punch hole 112 by the punch 12 to form a preliminary jewelry blank B. The outline of the preliminary jewelry blank B is close to the desired finished jewelry product. Then, the preliminary jewelry blank... B is placed in the molding groove 131, and the molding protrusion 113 is aligned with the molding groove 131 and pressed to form the jewelry blank B into a semi-finished jewelry product. The purpose of stamping the jewelry blank B here is to further shape the jewelry blank B, such as pressing a pattern on the surface, so that the overall shape of the stamped jewelry semi-finished product is basically the same as the jewelry product to be made. The last step is to place the molded jewelry semi-finished product on the punch 112, and punch off the rough edges around the jewelry semi-finished product through the punch 12 to obtain the jewelry product.

[0022] Alternatively, the punch, upper die, and lower die of this integrated stamping and punching manual jewelry mold can be mounted on a mold frame, and the punch and upper die can be driven by pressing the handle.

[0023] Furthermore, in another embodiment, such as Figures 1-2 As shown, the punch 12 and the punch hole 112 in the upper die 11 of this integrated stamping and punching manual jewelry mold are square punches and square holes for punching gold bars. The four corners of the square punch 12 and the square punch hole 112 are arc-shaped, and the length, width, and the size and shape of the arc edges of the corners are consistent with the gold bars to be molded. The molding groove 131 and the molding protrusion 113 are corresponding square grooves and square molding protrusions, respectively. Similarly, the four corners of the square molding groove 131 and the square molding protrusion 113 are arc-shaped, and the length, width, and the size and shape of the corners are consistent with the gold bars to be molded.

[0024] Furthermore, in another embodiment, such as Figures 1-2 As shown, the punch 112 of the manual jewelry mold that integrates stamping and punching passes through the upper mold 11 from top to bottom, so that the jewelry blank formed by punching can be directly dropped out and taken out from the punch 112.

[0025] Furthermore, in another embodiment, such as Figures 1-2 As shown, the lower die 13 of the manual jewelry mold that integrates stamping and punching has fixing holes at its four corners. The lower die 13 is fixed to the support platform through the fixing holes, which facilitates the molding of products.

[0026] Furthermore, in another embodiment, the molding groove of the integrated stamping and die-cutting manual jewelry mold is provided with pattern indentations or pattern protrusions for forming patterns on the underside of the semi-finished jewelry. These pattern indentations or protrusions can be text or decorative patterns. For example, a pattern indentation of "500 grams of gold" can be provided in the molding groove, thereby forming a "500 grams of gold" pattern protrusion on the bottom surface of the produced gold bar. Similarly, pattern indentations or pattern protrusions for forming patterns on the upper side of the semi-finished jewelry can also be provided on the molding protrusion.

[0027] In other embodiments, in addition to gold bars, the manual jewelry mold that integrates stamping and cutting can also be used to mold gold and silver rings, gold and silver pendants, gold and silver bracelets and other jewelry. Depending on the shape of the specific jewelry processed by the manual jewelry mold that integrates stamping and cutting, its upper mold, punch and lower mold can be made into corresponding shapes.

[0028] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
