Mold design (drawings) step by step
The first step of the design of the mold product feasibility analysis, computer chassis as an example, first of all the components of the product drawings using the design software for the analysis of the group, that is, we work in the set of drawings, to ensure that before the mold design of the correctness of the product drawings, on the other hand, can be familiar with the importance of each component of the chassis to determine the key dimensions, so that in the mold design is very beneficial. To determine the key dimensions, so that in the mold design is very beneficial, the specific set of drawings here will not do a detailed description of the method.
The second step, after the product analysis of the work to be carried out, the product analysis of what kind of mold structure, and the product row process, to determine the content of the process of punching, and the use of design software for the product development, in the product development, generally from the subsequent project forward to start, for example, a product needs to be amounted to five processes, stamping is completed in the product development from the product drawings to the four Project, three projects, two projects, a project, and expand a graphic after copying a copy and then carry out the previous project to expand the work, that is, the completion of the five projects to expand the work of the product, and then carry out detailed work, pay attention to this step is very important, and at the same time need to be particularly careful, this step is completed, then, in the drawing of the mold map will save a lot of time, the contents of the stamping of each project to determine the content of a good, including in the molding Mold, the product material thickness of the inner and outer retained to determine the size of the convex-concave mold when used, for the product to expand the method will not be described here, will be in the product to expand the method of specific introduction.
The third step, the preparation of materials, according to the product development plan for the preparation of materials, in the drawings to determine the size of the template, including the fixed plate, unloading plate, convex and concave mold, inserts, etc., note that directly in the product development plan for the preparation of materials, so that the drawing of molds is a great benefit, I have seen a lot of mold designers directly on the product development plan to prepare the material for manual calculations, the efficiency of this method is too low, directly on the drawing of the template specification size. Drawings drawn on the template specifications size, in the form of grouping diagrams, on the one hand, you can complete the preparation, on the other hand, in the mold of each accessory to save a lot of work, because in the drawing of each component of the work only in the preparation of drawings to join the positioning, pins, guide pillar, screw holes can be.
The fourth step, after the completion of the preparation of materials can be fully into the drawing of the mold, in the preparation of drawings and then make a copy of it out for the drawing of components, such as joining the screw holes, guide pillar holes, positioning holes, such as holes and in the punching mode of a variety of holes need to be wire cutting through the wire holes, in the molding die, molding clearance between the upper and lower molds, must not be forgotten, so after the completion of the work of the mold drawing of a product! Almost have completed 80%, in addition to drawing the process of mold drawing need to pay attention to: each process, refers to the production, such as clamping scribing, wire cutting and so on different processing procedures have a complete production of a good layer, so that the wire cutting and drawing management has a great deal of good, such as color differentiation, etc., the size of the labeling is also a very important work, but also a most troublesome work, because it is too much waste of time.
Simply put:
I. Learn from the three views, understand the concept of points, lines, surfaces and bodies. Learn about projections.
Two, find a mechanical drawing exercise book to practice seriously.
Three, study the course of mechanical drawing seriously.
Four, seriously study the national standard of mechanical drawing.
Fifth, then more drawings in kind, more practice on the line.
