A process for producing a molded item of thermosetting resin, and injection molding machine therefor, capable of preventing burring and bubble inclusion at molding operation. There is provided a process for producing a molded item of thermosetting resin with the use of a mold having a cavity for forming a product part, a gate forming a gate part, a runner forming a runner part and an overflow catcher communicating with the cavity and forming an overflow part, which process comprises the injection step of injecting a liquid resin until filling the region from the runner through the gate to the cavity and further the region from the cavity to the overflow catcher; the hardening step of heating the liquid resin within the mold so as to effect hardening; the demolding step of detaching a resin molded item having the runner part, gate part, product part and overflow part from the mold; and the cutting step of cutting the gate part and overflow part off the product part of the demolded resin molded item.
