Injection molding tool |
| abstract |
The structure comprises a fluid operated cylinder driving a piston rod in a barrel adapted to be connected to a mold for injection. The piston rod extends from one-half to two-thirds the length of the barrel whereby the molten portion of solid plastic cartridges is ejected by the piston rod pushing on the solid portion of the cartridges The piston rod has one or more lateral recesses to catch molten material that may escape rearwardly past the solid cartridges. Novel indicators are employed to monitor plastic flow. The inner surface of the barrel is tapered adjacent the outlet end thereof for efficient flow of molten material. The barrel at an ejecting nozzle thereof is heated by a torch or by a heat band secured thereto. An inner core is provided for efficiently mixing and heating the plastic. A thermocouple and an electrically operated display device are combined with a temperature adjusting device for providing controlled temperature conditions. A swivel support is mounted on the rear of the tool for supporting it in an operating function. In one embodiment, the piston for driving the piston rod is hydraulically driven by a gas pressure piston cylinder assembly connected thereto by a flexible hose. |
