Title Controller Of Injection Molding Machine
Inventorship Hajime Oono, Yamanashi (JP)
Assignee FANUC CORPORATION, Yamanashi (JP)

Claim of US Patent No. 9,090,015

1. A controller of an injection molding machine,
wherein the injection molding machine is provided with an injection member,
the controller controls the injection molding machine to perform metering and plasticization of a resin up to a metering completion
position in a metering process, to move forward the injection member while switching an injection speed at an injection speed
switching position in an injection process, and to proceed to a hold pressure process when a predetermined injection hold-pressure
switching condition is satisfied,

the controller includes:
an injection member position setting unit that sets a process value with respect to a process position of the injection member
and sets the process position of the injection member according to the set process value; and

a correction value setting unit that sets a correction value to correct the process position of the injection member, and
the injection member position setting unit sets the metering completion position and the injection speed switching position
as the process position of the injection member, at every predetermined cycle, using the correction value.
