Yet, the design guidelines can be summed up in just a few design rules. 已经有许多关于设计注塑模具的书了,但是设计准则可以被概括以下几点:\U)J9L7^CAD,CAE,CAM,ICAX,idesign,模具,设计,招聘,培训iCAx开思论坛9m$|h9VAhUse uniform wall thicknesses throughout the part. This will minimize sinking, warping, residual stresses, and improve mold fill and cycle times. 1.零件整体壁厚保持均匀.这样可以最小化缩坑,翘曲,强度减小,模具填充和循环时间.@Omqp1FzCAD,CAE,CAM,ICAX,idesign,模具,设计,招聘,培训4Ln

Using the least wall thickness for the process ensures rapid cooling, short cycle times, and minimum shot weight. All these result in the least possible part cost. www.iCA3[G+d ^\ W3.根据工艺,材料,产品设计需求.采用最小壁厚.最小壁厚的应用可以确保快速的冷却,短循环时间和减少喷射重量.所有这些最终达到最小的产品成本.2u4H8D(t:PV] ZpeCAD,CAE,CAM,ICAX,idesign,模具,设计,招聘,培训Design parts to facilitate easy withdrawal from the mold by providing draft (taper) in the direction of mold opening or closing.

This avoids the use of thick section to achieve the same, thereby saving on part weight, material costs, and cycle time costs. 5.为了提高产品强度抵抗弯曲应该加筋或肋.避免用厚的结构达到同样的效果,以此减少了产品重量,材料成本,循环时间成本.

Adding ribs increases the moment of inertia, which increases the bending stiffness. Bending stiffness = E (Youngs Modulu
