Patent ID: 11077595

Abstract:
A side-gate injection molding apparatus and a side-gate nozzle assembly are disclosed. The side-gate nozzle assembly delivers moldable material to a cavity insert that is beside the side-gate nozzle assembly. The side-gate nozzle assembly includes a nozzle body having a nozzle flow channel and a widthwise slot extending across a downstream side of the nozzle body. The nozzle flow channel has an outlet that ends at a wall of the slot. A load component is received in the slot and has a load component flow channel in fluid communication between the nozzle body outlet and an outlet at an end of the load component. A side-gate tip assembly is adjacent to the end of the load component and is in fluid communication between the load component flow channel and the cavity insert. In operation, thermal expansion of the load component presses the side-gate tip assembly towards the cavity insert.
