增大模具壁厚尺寸,可以提高模具的承载能力,但这不是有效而经济的办法。如果改变模具的设计方法,将单层设计成双层(或多层)组合模,采用冷缩压配工艺,制成予应力模,那么即使不增加壁厚,也能增大承载能力。一个内径为φ101.60mm,外径为φ203.20mm 的单层模,如改设计为内模外径为φ152.40+~(0.127)mm,外模内径为φ152.40mm,外
Increase the size of the mold wall thickness, can increase the carrying capacity of the mold, but this is not an effective and economical way. If you change the design of the mold, the single layer is designed as a double (or multi-layer) combination of molds, using shrink-compression process, made prestressed mode, then even without increasing the wall thickness, but also increase the carrying capacity. A diameter of 101.60mm, an outer diameter of φ203.20mm single-layer mold, such as the design of the inner diameter of the outer mold for the φ152.40 + ~ (0.127) mm, the outer diameter of the mold φ152.40mm, outside
