The Plastic Mold Design of Telephone HandsetCover
Abstract
Mold is widely used in industrial production the main technological equipment, It is an important means of modern industrial production and process development direction ,Many modern industrial development and the improvement of the technical levels ,Largely depends on the development of die and mold industry level.
The characteristics and developments of injection mold will be introduced in this paper. The designing and calculating of injection mold of microphone will be stated in detail. The forming process of the product and the structure characteristics as well as working process of the injection mold will be introduced .The attention should be paid in the design of the injection mold for the part with lifters also will be stated.
Using this mold can guarantee plastics dimension appearance and surface requirements,And low cost, simple structure and easy to open mold, high efficiency, with strong practicability.
Key Words: microphone;injection mold;core pulling
