modeling and hot runner mold design for Mouse cover
Abstract: This topic sets an example of injection mold design on the mouse cover , Introducing injection mold design methods and processes. First of all, according to plastic materials and process characteristics, analyzing the right parts, and then selecting the number of injection molding machine and to determine the cavity, and then determining a forming the program: the overall structural design, sub-surface design, casting design, mold release mechanism design, cooling system design. Finally, checking injection molding machine parameters, including the injection volume, clamping force, injection pressure, mold thickness and the injection machine shut height and so on. It is a model of the superstructure on UG software, which can be more directly to the entire mold bodies and have a more intuitive understanding .The design structure of products of other different injection mold design has some reference value.
Key words: structure; hot runner; mold
