Latest Patents

One of Hosokawa's key inventions is the traction type electric injection molding machine. The objective of this invention is to provide a machine that requires only one electric motor for mold clamping and a single rotational transformer. This design features a mold clamping apparatus installed on the top of a bed, positioned between the front and rear ends. The injection apparatus is also strategically placed between these components. The machine includes a fixed platen and a supporting platen, which are mounted oppositely on the bed and connected by tie bars. The traction rods insert through the platens, with their ends protruding. The tip ends of these rods carry a movable platen, allowing movement toward and away from the fixed platen. The rear ends of the traction rods are connected to a traction plate. The mold clamping apparatus incorporates a motion transformer, which consists of a screw shaft and a nut. The screw shaft is fixed to the traction plate, while the nut is rotatably supported inside the supporting platen and fitted with a pulley. Additionally, a screw preplasticating injection apparatus is supported over the bed, positioned between the fixed and supporting platens, and is slidably mounted on the tie bars.
