Semi-automatic injection molding induction device

The utility model discloses a semi-automatic injection molding induction device. The semi-automatic injection molding induction device comprises a work table, an electromagnetic inductor, an induction contact, a spring and a spring bolt, wherein the left part and the right part of the work table adopt ladder-like structures, and the right part is higher than the left part; the spring bolt is fixedly mounted on the top surface of the end part of the ladder on the left end, a cut-through mounting groove is formed between the upper and lower surfaces of the ladder on the left end, an induction contact bracket is hinged in the mounting groove, the induction contact is fixedly mounted at the upper part of the induction contact bracket, the electromagnetic inductor is fixedly mounted on the top surface of the ladder on the right end, the induction end of the induction contact and the induction end of the electromagnetic inductor are oppositely arranged, one end of the spring is mounted at the left end of the induction contact, and the other end of the spring is mounted at the top of the spring bolt. Through the technology, the change of a ball type switch which fails due to wear and oxidation is avoided, material and time are saved, the production process is more stable, the product quality is further ensured, the electromagnetic inductor more rapidly responds, and the production efficiency is improved.
