Design of Plastic Gear Mold and Its Cavity simulation of machining
Abstract: This topic comes from the plastic industry in JIA Yu, Yancheng. The task is to design the plastic gear mold and simulate its cavity. Injection molding is an important method of plastic molding, which is mainly suitable for thermoplastic molding, and can be used for one-time molding of precision plastic parts with complex shapes. This topic is based on the design model of double gears and the related knowledge of injection mold, and expounds the design process of plastic injection mold.
In this design, the injection mold of the double gear is designed, the plastic parts are modeled by proe software, and the process analysis of the plastic parts structure is carried out. The design idea is clarified, the injection molding process is determined, and each specific part is calculated and checked in detail. The structure designed in this way can ensure the reliable operation of the mold and the cooperation with other parts. Finally, the cavity is simulated by mastercam.
Through the design of the injection mold with double teeth cup, this subject has consolidated and deepened the knowledge learned, achieved satisfactory results and achieved the expected design intention.

Design of gear injection mold and cavity simulation of machining
Abstract: This topic comes from Yu Jia Plastics Company. The design of injection mold and cavity simulation of machining for gear plastics is an important method of plastic injection molding, which is mainly suitable for the molding of thermoplastic plastics and can be used to mold precision plastic parts with complex shapes. In order to study this topic, we take the double gear as the design model and elaborate the design process of injection mold based on the relevant knowledge of injection mold.
In the design, we designed the injection mold design of the double gear, modeled the plastic parts with proe software, and analyzed the process of the plastic parts. We defined the design, determined the injection molding process and calculated and verified some specific details. The structure of this design can be used to ensure reliable die work and ensure the cooperation with other parts of the sleeper. Finally, the cavity is simulated by mastercam.
Through the design process of the double gear die, the learned knowledge has been consolidated and deepened, and satisfactory results have been achieved, reaching the expected design intention.
