The principle of designing precision mold structure

In the stamping production process, the mold is an important means and plays a very important role. If you want to improve its utilization level, and thus further bring convenience to people's production and life, you must increase efforts to treat it. The design and optimization of the production process and its structure is a major development trend in the field of mold production, and it is also a problem that relevant personnel must pay attention to. The design process of stamping dies is very complicated and has a large degree of professionalism. In order to make its development further meet the requirements of the society, in addition to ensuring the professionalism of the designers, it is necessary to adhere to certain principles. The only thing we can do is to make the production process of the mold more reasonable, and at the same time to make it more in line with the relevant design standards, which has important value for its performance and service life. There are many types of cold stamping dies. In the design, a reasonable stamping die structure must be determined and selected according to the processability and production requirements of the stamping parts. The selection principles are as follows: 1. The simple stamping die is determined according to the production batch of stamping parts. The structure is still a complex die structure. Generally speaking, the simple die structure has a short life and low cost, while the complex die structure has a long life and high cost. Therefore, if the number of stamping parts is small, a simple die structure is more appropriate, and if the number is large, a conventional die structure with a longer life is more appropriate. 2. Determine the accuracy level of the die according to the size requirements of the stamping parts. If the dimensional accuracy and cross-sectional quality of the stamping parts are high, the precision die structure should be used, and the ordinary die structure can be used for the stamping parts with general accuracy requirements. 3. Choose the type of die according to the capacity of the existing equipment. For example, when drawing a workpiece, in the case of a double-action press, it is much better to use a double-action die structure than a single-action die structure. 4. Choose the type of unloading device in the die structure according to the thickness of the punched sheet. For example, when punching thicker sheet metal workpieces, if the requirements for surface flatness and tipness are not high, a fixed unloading device can be used. When blanking or blanking parts have higher requirements for surface flatness, It is more appropriate to choose an elastic discharge device. 5. Choose the mold type according to the technical conditions and economy of mold making. For example, when the mold-making technology requirements are low, a simpler die structure should be designed as much as possible. When the mold-making equipment is complete and the processing accuracy is high, in order to increase the service life of the mold and achieve mass production, then A more complex precision die structure should be used. The designer should consider many factors when selecting the structure of the die. Because both simple punching dies and general conventional punching dies have their own advantages and limitations. This requires a comprehensive analysis and comparison to make the selected stamping die structure as reasonable and reliable as possible.
