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. The specific method of group drawing will not be introduced in detail here.
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 usually starts from the subsequent projects. For example, a product needs five processes, and after stamping, it starts from the product drawings to four projects, three projects, two projects and one project. After expanding a graphic, make a copy before expanding the previous project, that is, complete the product expansion work of five projects, and then carry out detailed work. Note that this step is very important and requires special care. If this step is completed well, it will save a lot of time when drawing the mold drawing. After determining the stamping content of each project, including the forming die, the inner and outer lines of the product material thickness are reserved, and the size of the convex and concave die is determined for product development.
3. Material preparation: according to the product development drawing, determine the template size in the drawing, including fixed plate, discharging plate, convex-concave die, insert and so on. Paying attention to preparing materials directly in the product development drawing is of great benefit to drawing the mold drawing. I have seen many mold designer directly calculate product development drawings to prepare materials. This method is too inefficient, so the template specifications and dimensions are directly drawn on the drawings and expressed in the form of assembly drawings. On the one hand, it can complete the material preparation, on the other hand, it saves a lot of work in the work of each part of the mold, because only positioning, pins, guide posts and screw holes need to be added in the material preparation 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, etc. Moreover, in the stamping die, the forming gap between the upper and lower dies must not be forgotten, so the die drawing of a product is almost 80% after these works are completed. In addition, in the process of drawing the die drawing, it refers to making, For example, different processing procedures, such as scribing and wire cutting, have complete layers, which is of great benefit to wire cutting and drawing management, such as color discrimination, and dimensioning is also a very important and troublesome work, because it takes too much time.
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.
