Injection Molding Design Guidelines注塑模具设计指导

File Name Injection Molding Design Guidelines注塑模具设计指导 Introduction Much has been written regarding design guidelines for injection molding. 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: Use 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. Use generous radius at all corners. The inside corner radius should be a minimum of one material thickness. 2.在转角处大量采用圆角.圆角内部最小半径为一个壁厚. Use the least thickness compliant with the process, material, or product design requirements. Using the least wall thickness for the process ensures rapid cooling, short cycle times, and minimum shot weight. All these result...

Understanding Product Design for Injection Molding

Understanding Product Design for Injection Molding (Hanser Understanding Books) By Herbert Rees Publisher:   Hanser Gardner Pubns Number Of Pages:   116 Publication Date:   1996-06 ISBN-10 / ASIN:   1569902100 ISBN-13 / EAN:   9781569902103 During the more than 40 years the author has worked designing molds for plastics products, he has had many occasions to view and discuss product designs with their designers. Usually, the contact with the designer was established only after a purchase order for a mold had been placed to produce a certain product. In reviewing the supplied drawings, and occasionally models, many questions had to be answered before starting to design and build a practical mold, suitable for the plastic, for the requirements of the product, and for the planned production and mold life expectancy. Many product designers have excellent ideas when coming up with new products and improvements to existing ones, but often they apply design...
