Inject mold Design of Covert Camera shell
Abstract: The main topics for the plastic mold design Covert camera shell heat. Through process analysis and comparison for the plastic parts, the final designs of forming die. The subject from the hot plastic parts of the structure process, the specific structure of the mold, the mold gating system, forming part structure, ejecting mechanism, the cooling system, the choice of injection molding machines and related parameters of the check, the detailed design. Through the entire design process that can be achieved in the mold processing technology, the demand of this product. According to the topic, the main task of the design is the design of shell mold. According to the specific structure of the lower cover shell, double type using point gate injection molds, cover using a single type of submarine gate mold surface. According to the actual situation and, under the cover adopts hydraulic core pulling and oblique guide pillar core pulling two core pulling mechanism, the upper cover adopt oblique to lead post core pulling mechanism, and the mechanism of theoretical calculation and analysis, to ensure that the forming of parts can be achieved.
Key words: Camera shell; thermoplastic molding; core pulling mechanism.
