ラピッドプロトタイピング成形冷却管のGAによる設計に関する研究

摘要

Plastic parts are increasing used to substitute metal parts in the worldwide for plastic products have a low cost and high productivity. However, the merit of plastic products will disappear if cooling not enough. Generally speaking, cooling channel is consisted of straight-line cooling channel or cooling channel combination in a mold. This way has a demerit, which is freedom low, and caused uneven temperature distribution on the product surfaces. To resolve this problem, we proposed the block laminated method. This way is use laminated block to create a space with a particular shape in the mold. Block laminated method have some merits, for example, Cooling channel has a high freedom and easy to obtain a uniformity cooling. However, the core block will deform with the cooling channel increase and mold wall decrease, which cause the product defects. At present, for this way there is a problem, which is that there is not a proper method to evaluate surface temperature of product, deformation of mold, and design the cooling channel. So, our research objective is define an evaluation function, discuss the surface temperature distribution, mold deformation and automatic generate cooling channel.
