谁帮我翻译一下毕业设计摘要-谢谢了

The injection molding is one of thermoplastic formation main methods, may a formation shape complex model precisely. Along with the computer technology's development as well as the specific keyboard's demand, also set the new request to pressed key's design. This design has carried on the computer keyboard pressed key - Shift key's note mold design, has carried on the process study to the components structure. Had determined a minute profile, the gating system and so on, has chosen the injection machine, has calculated the formation spare part size. Uses the ambush type runner. Uses the straight guide pillar guidance, the throwout lever top material, the straight roof bar completed the drawing of patterns and has carried on the choice to mold's material. So designs the structure may guarantee that the mold work utilization is reliable. Finally has carried on the examination to the mold structure and the injection machine match. And has drawn up a set of mold asse
