【Abstract】On the topic of this design is inertial motion toy tanks shell design and injection mold design, so the design is based on the premise of thermoplastic plastic molding technology, and injection molding technology is one of the important methods. I'll be the first to in the design on the structure characteristics of injection products and shape structure analysis technology, and through the process and the actual situation to choose ABS as the material of products. Also need for plastic pieces of the parting surface position selection argument analysis, and according to the requirements of the mould different parameters to choose the appropriate injection molding machine models.The design of gating system was described in detail, demoulding structure, launch mechanism, cooling and exhaust system analysis design, and the characteristics of the mould structure and injection molding machine matching for checking. Finally die set 3 d assembly, and 2 d figure of the parts parts drawing and assembly drawing.
