Mold design steps

1, the design of mold products for feasibility analysis, to computer chassis for example, first of all, the component product drawings using design software for group analysis, that is, the set of drawings in our work, to ensure that the mold design before the correctness of the product drawings, on the other hand, you can familiar with the importance of the components in the entire chassis, to determine the key dimensions , so in the mold design is very good, the specific set of diagram methodhere does not do a detailed introduction.
2, after the product analysis to carry out the work, the product analysis of what kind of mold structure, and the product scheduling process, determine the process of punching content, and use the design software for product expansion, in the product expansion generally from the follow-up project forward, for example, a product needs to measure five operations, Stamping completion in the product start from the product drawings to four engineering, three engineering, two engineering, one project, and after the development of a graphic copy of the previous project to carry out the work, that is, completed the five engineering product scommencement work, and then carry out detailed work, note that this step is very important, at the same time need to be particularly careful, This step is done well, in the drawing of mold diagram will save a lot of time, after the content of each project stamped, including in the molding mold, the product material thickness of the inner and outer line retention, to determine the size of the convex mold when used, for the product expansion method is no longer explained here, will be specifically introduced in the product expansion method.
3, according to the product expansion map for preparation, in the drawing to determine the template size, including the fixed plate, discharge plate, convex mold, mounting, etc. , pay attention to directly in the product unfolding diagram for preparation, so that the drawing of mold map is of great benefit, I see a lot of mold designers directly on the product unfolding map manual calculation to prepare materials, This method is too low efficiency, directly on the drawing of template specifications, in the form of a group chart, on the one hand can complete the preparation of materials, on the other hand, in the mold parts of the work to save a lot of work, because in the drawing of the components of the work only need to add positioning, pins, guide posts, screw holes can be added in the preparation drawing.
4, after the preparation can be fully into the mold map drawing, in the preparation drawing sand sheet to make another out, to draw the components, such as adding screw holes, guide column holes, positioning holes and other hole positions, and in the punch ingenhole in a variety of holes need to be cut wire piercing, in the molding, the molding gap up and down mold, must not forget, So after the completion of these work a product mold map has almost completed 80%, in addition in the process of drawing the mold map to pay attention to: the process, refers to the production, such as fitter dash, line cutting until different machining processes have a complete production layer, so that the line cutting and drawing management has great benefits, such as color distinction, etc. Dimensioning is also a very important job and the most troublesome work because it’s a waste of time.
5, after the completion of the above drawings, in fact, can not issue drawings, but also need to proofread the mold drawings, all accessories, each different mold plate to make a different layer, and the same benchmark such as guide column holes wait until the mold group analysis, and the operation products expand into the group standup, Make sure that the holes of each template are consistent and that the upper and lower mold clearances in the bend position fit correctly.
