【Abstract】 The temperature system during injection is the key factor affecting the production efficiency and the quality of plasties part. Based on the steady temperature field analysis and by weighted finite difference method, the mathematic model of calculat ing the transient temperature field of the part was built up in this paper through dividing the regions of space and time into a number of subdomations or elements respectively. And the distribution of temperature at each moment was presented.更多还原
