Analysis on the structure characteristics of metal stamping parts die

The nozzle of the metal stamping die is on the front mold, and the nozzle of the flip die is on the back mold (the side where the ejector pin is ejected), that is to say, the injection and ejection are the same side. Today, the author and everyone will analyze the formal mold first, and then analyze the flip mold in the future. 1 The structural characteristics of the formal mold: The structural characteristic of the normal metal stamping mold is that the concave mold is installed on the lower mold seat. Whether it is blanking, punching, or other processes of the workpiece, the workpiece or waste can easily fall into the waste hole on the punching table. Therefore, there is no need to consider the flow direction of the workpiece or waste when designing the formal assembly mold. Therefore, the designed mold structure is very simple and very practical. 2 Advantages of the mold structure of the formal hardware stamping parts: (1) Because the mold structure is simple, the mold manufacturing cycle can be shortened, which is conducive to the research and development of new products. (2) It is more convenient to use and maintain. (3) It is more convenient to install and adjust the gap between the convex and concave molds (relative to the flip chip mold). (4) The mold manufacturing cost is low, which is conducive to improving the economic benefits of the enterprise. (5) Since there is always a blank holder force during the entire stretching process, it is suitable for the stretching of non-rotating parts. 3 Disadvantages of the die structure of the metal stamping parts for formal mounting: The accumulation in the hole increases the group tension in the cavity of the die. Therefore, the wall thickness of the concave must be increased to increase the strength. (2) Due to the accumulation of metal stamping parts or waste in the cavity of the cavity, under normal circumstances, the cutting edge of the cavity must be processed with a blanking slope. In some cases, the reverse hole (discharge hole) of the die edge is also processed. Therefore, the production cycle of the mold is prolonged, and the processing cost of the mold is reduced. 4 The selection principle of the mold structure of the formal hardware stamping parts: When designing the die, the design principle that should be followed is: the formal mold structure should be selected first. Only when the technical requirements of the workpiece can be met under the formal mold structure, other forms of mold structure can be considered.
