绘制模具结构图（Draw mold structure drawing） Draw mold structure drawing First, when the finished map into mould drawing, drawing must be finished by shrinking. (die size = product size * shrink) must be finished in figure MIRROR (mirror) once, namely die circle is like the finished map (except the finished product is completely symmetrical) before die, the die does not belong to the top line in the rear mould should be deleted, does not belong to after die delete line repair. Two, the finished products in the mold should follow the principle of points in, especially symmetrical, finished products, if not divided, to the factory processing is likely to make mistakes. Three, all pillow mold, pillow must avoid access to water, can not avoid to add water, mouth iron. Four, product between 12 - 20mm (special circumstances, can be used as 3mm) when diving into the water is sufficient, diving location, finished to CORE side 15-50mm, margin to CORE and finished products storage of general products can refer to the table of selected numerical experience. Product thickness (mm) finished to CORE edge value (mm) 2015 - 20 20 - 3020 - 30 30 - 4030 - 40 4050 Five, Tibetan CORE (internal model material) depth of more than 28mm, before and after the mold thickness and the product surface projection area, general products can refer to the following table, empirical value selected. CORE material side to back needle should have 10mm distance. The flat projection area of the product, the inner mold thickness of the front mold, the depth of the A+ cavity, the thickness of the internal mold material and the depth of the B+ cavity SP, CMmmMm 772532 77 - 1163238 116 - 1543850 154 - 1934464 More than 1935076 CORE material width is generally higher than the thimble very wide or narrow 5 10mm, the minimum should be in the finished rubber thimble plate has no effect on falling edge to mold thimble, CORE material boundary should be 45 - 80mm Six, when an internal mold material on a number of CAVITY,
