  • Patent number: 8070471
    Abstract: A molding apparatus includes a bottom platen, a bottom mold portion carried by the bottom platen, and a top platen overlying the bottom platen and the bottom mold portion. The top platen includes slots extending therethrough for receiving a molding material. The molding material is to be gravity deposited into the bottom mold portion. A top mold portion is carried by the top platen and is moveable between a molding material loading position and an article forming position. An actuator is coupled to the top mold portion for moving the top mold portion between the molding material loading position and the article forming position. The molding material loading position corresponds to when the top mold portion is non-overlying the bottom mold portion so that the molding material can be gravity deposited therein. The article forming position corresponds to when the top mold portion is overlying the bottom mold portion for molding an article.

  • Patent number: 8022580
    Abstract: A plastics injection-molding machine is to be equipped with a more compact drive that undergoes less wear. For this purpose, it is envisaged to integrate the direct rotational drive into the direct linear drive. Accordingly, the electric linear motor has a pot-shaped external rotor (13), in the inner space of which the main part of a hollow-cylindrical stator (16) of the linear motor is arranged and which is firmly connected to the output shaft (10). The rotary drive has a stator (18), which is mounted on the inner wall of the hollow-cylindrical stator (16) of the linear motor, and a rotor, which is firmly coupled to the output shaft (10) within the stator (18) of the rotary electric motor. This direct drive produces a very compact type of construction and it is possible to dispense with easily wearing threaded spindles.
