The designing and calculating of injection mould for the back of electronic clock were stated in detail. The forming process of the product and the structure characteristics as well as working process of the injection mould were introduced .The points must be paid attention to in the design of the injection mould for the part with lifters were stated.In the process of the designing of the injectinon mould for electronic clock receiver, people should pay attention to several suggestions: the plastic should be designed as reasonable as possible. The selection of the sub-type parts are benificial? to mold the parts of plastic. The design of the? structure of drawing of pattern is not only simple but also the movement should be stable and reliable. The selection of Jin runner should ensure to fill the plastic equally under the prerequisite of not influencing the appearance of the plastic. The design of cooling penstock should make the rate of production reach to the topmost, and ensure any influence to do nothing to the equality of the plastic. Meanwhile, in the process of designing ,we can use analysis soft, such as CAM, to make the design been more reasonable? and efficient. Making full use of? large amounts of standard pieces will reduce the cost of mold plastic facture. The key point of the design of mold plastic have reached the request of the real production.?
