Mold Design Steps
Oct 10, 2006

1. To analyze the feasibility of the product of the mould design, take the computer chassis as an example, first of all the components of product drawings using design software for the group analysis, that is, we work on the set of drawings to ensure that the mold design before the correctness of the product drawing, on the other hand can be familiar with the components in the entire chassis of importance to determine key dimensions, This in the mold design is very good, the specific set of diagram method here does not do a detailed introduction.

2. The work to be done after the product analysis, analysis of the product using what kind of mold structure, and the product to arrange the process, determine the process of stamping, and the use of design software for product launches, in the product launches generally from the follow-up project, such as a product needs five of processes, Stamping is completed in the product launches from the product drawing to the four project, three projects, two projects, a project, and the expansion of a graphic after a copy of the previous project to carry out the work, that is, completed five of the project product launch work, and then carry out meticulous work, attention, this step is very important, at the same time need to be particularly careful, If this step is done well, it will save a lot of time in drawing the stencil diagram, for each project stamping content determined, including in the molding, the product material thickness of the inner and outer lines retained to determine the concave and convex modulus of use, the product expansion of the method here no longer explained, will be in the product expansion method specific introduction.

3. preparation, according to the product expansion diagram for preparation, in the drawings to determine the size of the template, including the fixed plate, unloading plate, concave and convex mold, inserts and so on, attention directly in the product expansion diagram for preparation, so that the drawing of the mold is a great advantage, I have seen a lot of mold designers directly to the product expansion diagram manual calculation to prepare, This method is too inefficient to draw the template size directly on the drawing, in the form of the formation of the group diagram, on the one hand can complete the preparation, 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 in the preparation of drawings to add positioning, pins, guide pillars, screw holes can be.

4. After the preparation is complete, you can fully enter the drawing of the die drawing, and then make a copy of it in the drawing. The drawing of each component, such as adding screw hole, guide pillar hole, locating hole and so on hole position, and in the punching die in all kinds of holes need wire cut through the wire hole, in the molding mold, upper and lower mold forming gap, must not forget, So after the work is done, a product's mold chart is almost 80%, in addition, in the process of drawing the mold drawing should pay attention to: each process, refers to the production, such as fitter line, wire cutting wait for different processing processes have a complete production layer, so on line cutting and drawing management has great benefits, such as color discrimination, Dimensioning is also a very important job, and it is also one of the most troublesome jobs because it is a waste of time.

5. After the completion of the above drawings, in fact, can not release drawings, also need to proofread the mold drawings, all the accessories will be set up, for each of the different mold plate production of different layers, and the same benchmark, such as guide hole waiting for the Die group analysis, and the process of product expansion diagram into the group, Make sure that the holes in each template are consistent and that the upper and lower clearance of the bend position fits properly.
