This topic mainly aims at the mold design which The Water Injection bottle top of the label of jikang, through to models to carry on the craft the analysis and the comparison, designs a note mold finally. This topic from the product mix technology capability, the concrete mold structure embarks, to mold's gating system, the mold formation part's structure, goes against the system, the cooling system, injection molding machine's choice and the related parameter examination, has the detailed design, simultaneously and simple establishment mold's processing craft. Through the entire design process indicated that this mold can achieve this to model the processing craft which an institute requests. It is The Water Injection bottle top of the label of jikang according to the topic design's primary mission injection mold's design. It also designs an injection mold to produce The Water Injection bottle top of the label of jikang to attach models a product, realizes the automation to raise the output. Concrete structure which attaches in view of The Water Injection bottle top of the label of jikang, this mold is runner Shan Fen the profile injection mold. Because models both sides to be interlinked, also has the thread, must therefore use revolving to pull out the core organization and the side pulls out the core organization to realize. Considered the structure the particularity, its merit lies in two step movement to be possible also to carry on, and the movement is keen. Because the plastic parts connect at both ends, have thread, take into account that the material is soft, and the mould of internal thread is semi-circular and only two laps, it take the way of the core mechanism to achieve external thread, and internal thread use the way of force pull mode.
