Abstract

The utility model provides a programmable logic controller (PLC)-control-based double-layer injection mold. The double-layer injection mold comprises a first injection part and a second injection part. Main body structures of the two injection parts are the same, and forming cavities formed by female and male mold cores can be different. The mold closing surfaces and ejector mechanisms of the two injection parts are controlled by a PLC. During the mold opening of each time, only one mold closing surface is opened, mold opening, mold closing and ejection action are executed, then the mold closing surface of the other injection part still executes mold closing cooling action, and the two injection parts are not interfered. Therefore, time can be comprehensively arranged, and yield can be approximately doubled.
