Abstract

The invention discloses an electric meter and a processing method thereof. The processing method comprises the following steps of: a, plasticizing: adding plastic into an injection molding machine for heating until the plastic is in a molten state; b, injecting: injecting the plastic in the step a into a mold; c, maintaining pressure: maintaining the pressure through uniform injection; d, cooling and demolding: demolding after cooling and molding for 38s, wherein the injection molding machine in the step a comprises a main body, an injection molding nozzle, a working port, a discharging port and an injection molding device; and the injection molding device comprises a motor, an injection molding cavity, an injection molding roller, four moving grooves, a moving device, a mold, an injection molding port and a discharging device. According to the processing method, the uniformity of injection molding is improved through the pressure maintaining step, and the quality of an electric meter shell is further improved; the injection molding roller realizes a non-stop injection molding effect by rotating and exchanging a plurality of molds; the injection molding efficiency is further improved; and the mold can be automatically opened for discharging through the discharging device, the cooling time can be guaranteed, and the injection molding effect is further improved.
