Abstract
A differential carrier case with an inserted pipe for high pressure casting may include a mold core into which a first end of a pipe is inserted, a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe, a drive core pin inserted into a second end of the pipe, and a thick portion surrounding an outer portion of the pipe.
Claims9
A differential carrier case with an inserted pipe for high pressure casting, the differential carrier case comprising:
- a mold core into which a first end of the pipe is inserted;
- a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe;
- a drive core pin inserted into a second end of the pipe;
- and
- a first portion surrounding an outer portion of the pipe.
A method of manufacturing a differential carrier case with an inserted pipe for high pressure casting, the method comprising:
- two-axis fixing of the pipe, in which a first end of the pipe is inserted into a mold core, and the pipe is inserted and fixed to a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe;
- three-axis fixing of the pipe, in which the pipe is fixed by a drive core pin inserted into a second end of the pipe;
- and
- high pressure casting, in which molten metal is casted by being injected into the mold core under pressure higher than a predetermined pressure.
