PURPOSE:To enhance demolding efficiency and to make it possible to deliver a product part and a scrap part in a separated state, by a method wherein trimming in a mold is performed at the closing stage of hot pressing molding and suction through a gas vent hole is continued even after hot pressing molding to attract a wooden series molded body to an upper mold and, after mold opening, positive pressure is supplied to the gas vent hole. CONSTITUTION:The projection 1b of an upper mold 1 gets into the recessed part 2b of a lower mold 2 at the closing stage of hot pressing molding and a molded body P is divided into a product part P1 and a scrap part P2. Change- over valves 9a, 9b are opened to continue gas venting even after dividing. After compression molding was completed, the molds are opened to take out the product part P1 and the scrap part P2 to the outside of a holding frame in a state attracted to the lower surface of the upper mold 1. Thereafter, positive pressure is supplied to the gas vent hole to detach the product part P1 and the scrap part P2 from the upper mold 1.
