PROBLEM TO BE SOLVED: To provide a low-cost injection molding device featuring a short molding cycle. SOLUTION: This injection molding device includes a mold 1, a mold clamping means 30 for clamping the mold 1, an injection means 12 which fills the interior of the mold 1 with a molten resin by injection, pressure detection means 7 and 8 which measure the resin pressure inside the mold 1, and a mold clamping/release control means 34 which releases the mold 1 from its clamping state when the resin pressure reaches a pressure value set based on the peak value, in filling the interior of the clamped mold 1 with a molten resin by injection.
