Mold is an industrial product that shapes materials into specific structural forms in a certain way, and it is also a production tool that can mass-produce industrial product parts with certain shape and size requirements. Almost all industrial products, from airplanes and cars to teacups and nails, have to be molded with molds.
Mold design refers to the personnel engaged in the digital design of enterprise molds, including cavity molds and cold molds. On the basis of traditional mold design, they make full use of digital design tools to improve mold design quality and shorten mold design cycle.
Design steps:
1. Analyze the feasibility of the designed die products. Take the computer case as an example. Firstly, the design software, that is, the set of drawings mentioned in our work, is used to analyze the product drawings of each component to ensure the correctness of the product drawings before the mold design. On the other hand, we can be familiar with the importance of each component in the whole case to determine the key dimensions, which is very beneficial in mold design.
2. The work to be done after product analysis, what kind of die structure is used to analyze products, arrange products, determine the stamping content of each process, and use design software to expand products. When the product is unfolded, it is usually unfolded from the subsequent project. Before the previous project is unfolded, a graphic is unfolded and a copy is made, that is, the product unfolding work of the fifth project is completed, and then the detailed work is carried out.
3, material preparation, according to the product development diagram, determine the template size in the drawing, including all fixed plates, discharging plates, convex and concave dies, inserts, etc. And pay attention to preparing materials directly in the product development drawing, which is of great benefit to drawing the mold drawing.
4. After the material preparation is completed, you can completely enter the drawing of the die drawing, and make another copy in the material preparation drawing to draw all the parts, such as adding screw holes, guide post holes, positioning holes and other holes. In the stamping die, all kinds of holes need to be cut by wire, and in the forming die, the forming gap between the upper and lower dies is reduced.
5. After the above drawings are completed, it is actually impossible to draw. It is necessary to proofread the mold drawings, assemble all the accessories, make different layers for each different template, analyze the mold assembly with the same benchmark, such as the guide post hole, and put the product development drawing of each process into the assembly drawing to ensure that the hole position of each template is consistent and the gap between the upper and lower molds at the bend is correct.
