Title The plastic mould design of Mouse superstructure based on the moldflow simulation
Abstract
With the popularity of the computer ,mouse become essential items when
people work and study .This topic according to the provided 3D CAD model
of mouse superstructure, design a higher quality injection mold. First,
Using Pro / E software to complete the three-dimensional modeling of mouse
superstructure，and make a injection molding simulation using the Moldflow
software, to accurately predict the melt filling, packing, cooling as well
as the stress distribution, molecular and fiber orientation distribution
of products, such as shrinkage and warpage and thereby choose the closest
gate location, as well as providing the best solution for mould design.
Then, design the runner system，ejection mechanisms, side core-pulling
mechanism ,guide mechanism and fixed and installation position. Second,
use the Pro/E software to complete the structural design of mold, on the
basis of the shape , accuracy ,size, process requirements of mouse
superstructure and the design parameters from Moldflow software, according
to the corresponding design steps, eventually finish the plastic mould
design of mouse superstructure.

1 绪论
模具是制造业的一种基本工艺装备，它的作用是控制和限制材料（固态和液
态）的流动，使之形成所需要的形状。用模具制造零件以其效率高、产品质量好、
材料消耗低、生产成本低而广泛应用与制造业中[1]。
