Abstract
A simple injection molding machine structure including a stationary platen, a movable platen, and an injection unit, and an injection method for the simple injection molding machine structure are provided. The stationary platen and the movable platen each carry a mold core for defining a mold cavity. The movable platen is movable freely relative to the stationary platen. The injection unit is disposed on the movable platen and includes an injection barrel, a heating member, a screw rod and a driving member. The screw rod is coupled to the driving member, extended into, and received in the injection barrel. The heating member is disposed on the injection barrel. The screw rod pressurizes, injects, and delivers molten plastic. The simple injection molding machine operates by controlling the speed of advancement of the screw rod to stabilize pressure and thus allow the molten plastic to take shape easily.
