The invention discloses a waterproof type lifting electromagnet junction box. The waterproof type lifting electromagnet junction box comprises a junction box cavity, a junction box cover and an internal gland packing, wherein an outlet cable is guided out through a wire outlet formed on the side surface of the junction box cavity, the junction box cavity is formed by a mono-block casting method, the junction box cavity and the junction box cover are connected and fixed by an outer flange, and the upper edge of the junction box cavity is provided with a waterproof seam allowance. When in use, the waterproof type lifting electromagnet junction box is placed on a wire outlet of an electromagnet yoke plate, a cable passes through a gland nut and a sealing ring of the wire outlet and enters the junction box cavity to be connected with a binding post, silicone rubber is poured into the junction box cavity for solidifying the junction box cavity, and then the junction box cover is fixed on the outer flange of the junction box cavity by a bolt, thus, water cannot enter the junction box through the bolt, the waterproof seam allowance prevents water from flowing back into the junction box, the gland nut of the wire outlet compresses a rubber ring and holds the outlet cable for sealing, the junction box cavity is internally sealed by pouring the silicone rubber, and no gap exists between the rubber and the inner wall of the junction box cavity; and even if water enters the junction box, water cannot flow into a coil, and the waterproof problem of the junction box can be solved thoroughly.
