Abstract: Injection mold design for side cover of printer was introduced in this paper. There are many lateral concaves and bores in the part, so the inner and outer lateral openings should be applied in this mold structure. Under the premise to meet the requirement of configuration, the design simplified as far as possible. The Moldflow analysis was introduced to designs of runner and cooling systems so as to ensure the appearance quality and surface level. The designed mold was produced in batch and worked well, and thus provided a reference to similar plastic parts mold design.

Key words: Moldflow analysis, injection mold, printer side cover, lateral opening
