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 cosmetic plastic soft tube mold structure is used, and the product is discharged, the contents of each process are determined, and the product is developed by using the design software. When unfolding, it generally starts from the subsequent project. For example, a product requires five processes. When the product is completed, the product is started from the product drawing to the fourth project, the third project, the second project, the first project, and a graphic is copied. After the completion of the previous project, the product development work of the five projects was completed, and then the detailed work was carried out. Note that this step is very important and needs to be particularly careful. If this step is completed, in the drawing of the mold diagram. It will save a lot of time, after the content of stamping in each project is determined, including in the molding die, the inner and outer lines of the thickness of the product material are retained to determine the size of the convex and concave die, and the method for unfolding the product is not described here. It will be described in detail in the product deployment method.
3. Prepare materials according to the product development drawing. Determine the size of the template in the drawings, including each fixed plate, unloading plate, convex and concave mold, insert, etc. Pay attention to the material directly in the product development drawing. 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.
