Abstract
A vertical injection molding machine is provided with a base, a lower mold mounting unit, an injection device, a pressing mold unit, and an upper mold mounting unit. Since the pressing mold unit and the injection device are all disposed on the upper seat of the base, and therefore are located above the lower seat, the lower mold mounting unit, the upper mold and the lower mold. With this design, the height to the ground from the lower seat can be substantially reduced. Namely, the heights of the lower seat, the lower mold mounting unit and the upper and lower molds with respect to the user are reduced to an ergonomic height, which makes operation of the injection molding easier and convenient, while reducing danger and enhancing work safety.
Claims5
A vertical injection molding machine comprising:
- a base with a lower seat and an upper seat above the lower seat;
- a lower mold mounting unit disposed at the lower seat and provided for mounting of a lower mold and an upper mold;
- an injection device including a plurality of guiding shafts longitudinally disposed on the upper seat, an injection seat movably disposed on the guiding shafts, a feeding seat which is movable mounted on the guiding shafts and located between the injection seat and the upper seat, and an injection unit which is longitudinally disposed on the injection seat and inserted out of the feeding seat and includes an injection hole;
- a pressing mold unit including a pressing seat and a pressing mold shaft, the pressing seat being fixed in the upper seat of the base and including a longitudinal hole, the pressing mold shaft being movably inserted in the longitudinal hole and also including a longitudinal hole for insertion of the injection unit, and a lower connecting surface;
- and
- an upper mold mounting unit including an upper surface fixed to the lower connecting surface of the pressing mold shaft, a lower surface abutted against the upper mold, and a feeding passage which is in communication with the upper and lower surface and aligned with the injection hole;
- by such arrangements, the pressing mold shaft is controlled to move longitudinally back and forth to press against or disengage from the upper and lower molds, and the injection seat is controlled to move longitudinally back and forth to make the injection hole of the injection unit connect to or disengage from the feeding passage of the upper mold mounting unit.
