Abstract
This utility model belongs to the field of toy injection molding technology, specifically a plastic toy injection molding device, including a fixed platform and an injection mechanism installed on the fixed platform. The fixed platform is equipped with a molding mechanism, which includes a support plate and a guide rod. The support plate is fixedly connected to the fixed platform, and the guide rod is fixedly connected to the support plate. An injection cavity is formed between the fixed mold and the moving mold. The telescopic end of the cylinder is fixedly connected to a connecting column that is slidably connected to the push rod. The end of the connecting column has an installation port, and a pressure sensor located at the installation port is installed on the connecting column. A sealing plate is fixedly connected to the end of the connecting column. The side wall of the fixed mold has a connecting groove, and an air inlet pipe communicating with the injection cavity is installed on the fixed mold. By setting an automatic air tightness detection component inside the mold cavity, air tightness detection can be performed automatically at regular intervals to avoid burrs forming on the edges of the toy and dimensional deterioration.
