The sequence of drawing the part drawing from the general assembly drawing of the mold shall be: first inside then outside, first complex then simple, first molding parts, then structural parts.
1) Graphic requirements: be sure to draw according to the scale, and allow zooming in or out. The view selection is reasonable, the projection is correct, and the layout is appropriate. In order to make the processing patent number easy to understand and easy to assemble, the graphics should be consistent with the general assembly drawing as much as possible, and the graphics should be clear.
2) Dimensioning shall be unified, centralized, orderly and complete. The order of dimensioning is: first mark the size of the main parts and the die inclination, then mark the fitting size, and then mark all the dimensions. On the drawing of non major parts, the matching dimensions shall be marked first, and then all dimensions shall be marked.
3) Surface roughness. Mark the most applied roughness on the upper right corner of the drawing, como "Other 3.2" Other roughness symbols shall be marked on each surface of the part.
4) Other contents, como part name, mold drawing number, material trademark, heat treatment and hardness requirements, surface treatment, drawing proportion, machining accuracy of free size, technical description, etc., shall be filled in correctly.
