After the preparation is completed, the drawing of the mold drawing can be fully entered, and a part of the preparation drawing can be made to draw the components, such as adding screw holes, guide post holes, positioning holes, etc., and in the punching die. Various holes need to be cut through the wire.
1. Feasibility analysis of the products of the designed molds. Taking the computer case as an example, firstly, the drawing of each component product is analyzed by the design software, that is, the set of drawings mentioned in our work to ensure the product drawings before the mold design. On the other hand, you can familiarize yourself with the importance of each component in the entire chassis to determine the key size, which is very beneficial in the mold design. The specific pattern method is not described in detail here.
2. After the product analysis, the product to be analyzed, what kind of mold structure is used for the product, the product is discharged, the content of each process is determined, and the product is developed by using the design software. The follow-up project will be carried forward. For example, a product requires five processes. When the product is completed, the product starts from the product drawing to the fourth project, the third project, the second project, the first project, and a graphic is copied and then copied. The start of a project is to complete the product development work of the five projects, and then carry out detailed work. Note that this step is very important, and at the same time, it needs to be very careful. If this step is completed well, it will save a lot of time in drawing the mold diagram. After the content of the stamping of each project is determined, including in the forming mold, the inner and outer lines of the thickness of the product material are retained to determine the size of the convex and concave molds, and the method for unfolding the product is not described here, and will be unfolded in the product. The method is described in detail.
3. Prepare the materials according to the product development drawing, and determine the template size in the drawings, including the fixed plates, the unloading plates, the convex and concave molds, the inserts, etc., pay attention to the preparation directly in the product development drawing, so that the drawing is There are great advantages. I have seen many mold designers directly calculate the product development drawings by hand. This method is too inefficient. Draw the template size directly on the drawing and express it in the form of a group diagram. On the one hand, it can complete the preparation of materials, on the other hand, it saves a lot of work in the work of the various parts of the mold, because in the work of drawing each component, it is only necessary to add the positioning, the pin, the guide post and the screw hole in the preparation drawing.
4. After the material preparation is completed, the drawing of the mold drawing can be fully entered, and a part of the preparation drawing can be made out to draw the components, such as adding screw holes, guide post holes, positioning holes, etc., and punching holes. The hole in the mold needs to be cut by the wire. In the molding die, the forming gap of the upper and lower molds must not be forgotten, so the mold drawing of one product after the completion of these work is almost 80% completed, and the drawing is also drawn. Need to pay attention to the process: each process, refers to the production, such as the fitter scribing, wire cutting, etc. to the different processing steps have a complete production of the layer, which has great benefits for wire cutting and drawing management, such as color distinction, etc. The size of the label is also a very important job, but also the most troublesome work, because it is a waste of time.
5. After the above drawings are completed, in fact, the drawings cannot be issued. It is also necessary to proofread the mold drawings, assemble all the accessories, make different layers for each different mold plate, and use the same reference as the guide post holes. Perform mold assembly analysis, and insert the product development drawings into the group diagrams to ensure that the hole positions of the template are consistent and the gap between the upper and lower molds of the bending position is correct.
