Mold design refers to the digital design of an enterprise's molds, including cavity molds and cold punches. On the basis of traditional mold design, fully utilize digital design tools, improve mold design quality, and shorten the mold design cycle. Mold designers can be employed in the field of CNC programming, three-dimensional design of molds, and three-dimensional design of product development.
As the shortage of stocks in the mold industry gradually eased, the issue of mold design became a hot spot in the industry. Because of the joining of talents, the knowledge of various aspects of mold basic mold design is also different. Even more, with the expansion of the scope of the mold industry, the requirements for mold design are also increasing.
1. Feasibility analysis of the products of the designed molds. Taking the computer case as an example, firstly, the product drawings of each component are analyzed using the design software. That is, the sets of drawings that we described in the work ensure the product drawings before the mold design. The correctness, on the other hand, can be familiar with the importance of the components in the entire chassis to determine the key dimensions, so that in the mold design is very good, the specific set of map methods will not be detailed here.
2, after the product analysis, the work to be carried out, what kind of mold structure is used to analyze the product, and the product is discharged, the content of each process rush is determined, and the product is developed by using the design software, generally from the time of product development. Follow-up project to expand
For example, if a product requires five processes, the stamping process starts from the drawing of the product to the fourth, third, second, and first projects when the product is unfolded, and after a graphic is created, a copy is made and the next project is started. That is, the product development work for the five projects was completed, and then the detailed work was performed.
Note that this step is very important, and at the same time it requires special care. If this step is done well, you will save a lot of time in drawing the mold drawing. After determining the stamping content of each project, including the molding die, the thickness of the product material The inside and outside lines are reserved to determine the dimensions of the male and female molds. The method for product deployment is not described here and will be specifically introduced in the product development method.
3, mold CAD3, stock preparation, according to the product development plan for the preparation of materials, in the drawings to determine the template size, including the fixed plate, stripper plate, male and female mold, inserts, etc., pay attention to directly in the product development plan for preparation, so that the painting The mold drawing is of great benefit. I have seen many mold designers directly calculate the product development drawing manually to prepare the material. This method is too inefficient. Draw the template specification directly on the drawing to build the assembly drawing. The form of the statement, on the one hand can complete the preparation of materials, on the other hand in the work of the various parts of the mold to save a lot of work, because in the drawing of the components of the work only need to add the positioning drawings, pins, guide posts, screw holes can.
4, after the preparation is completed, you can fully enter the drawing of the mold drawing, make a copy out of the preparation drawings, and draw the components, such as adding screw holes, guide column holes, positioning holes and other hole positions, and in the punching Holes in the holes in the die must be cut by wire. In the forming die, the gap between the upper and lower die must not be forgotten. So after the completion of these jobs, the die drawing of a product has almost completed 80%.
In addition, the process of drawing the mold diagram should pay attention to: the various processes, refers to the production, such as bench marking, line cutting, etc. to the different processing processes have a complete production layer, this line cutting and drawing management has a great advantage, Such as the color of the distinction, the size of the label is also a very important task, but also the most troublesome work, because it is a waste of time.
5, after the above drawings are completed, in fact, it is still not issued drawings, but also need to proofread the mold drawings, set up all accessories, for each piece of different mold board to make different layers, and the same reference as the guide post hole wait Analyze the assembly of the mold, and put the product development diagrams of each process into the assembly diagram to ensure the consistency of the hole position of each template and whether the gap between the upper and lower molds in the bending position is correct.
After the above work, the mold drawing of a product is officially completed. The above is a general introduction to the direction and steps of the mold design. At the same time, each mold designer has its own method. Anyway, the design work is completed successfully. In addition, work efficiency is also very important. In fact, as long as the heart, each design may become a good work in the mold industry.
