According to the characteristics of an assembled toy’s connector, the structural design and working procedure of the injection mold are presented. Angle pin side-separating mechanism and gear-rack assembly core-pulling mechanism were applied to the forming and demoulding. The distance pull board was used to complete the second parting and scraped the product B. Ejector pins were used to eject the product A. Bolts and springs assured the angle pin go into the slide’s bore accurately when clamping the mold. The mold structure was compacted and working procedure was good and steady. The product can meet the requirements.
