Production of air bag cover for automobile and forming mold thereof

Abstract

Abstract PURPOSE:To prevent misregistration of reinforcing cloth and to produce an air bag cover for an automobile by placing the reinforcing cloth on a forming mold wherein many projecting parts having a stopping recessing part are formed and pinching yarn of reinforcing cloth by the stopping recessing part and closing the forming mold and introducing resin. CONSTITUTION:Mold release liquid 28 is applied to an inner mold 21 and reinforcing cloth 27 is placed on the inner mold 21. Warp or weft of reinforcing cloth 27 is engaged with the respective stopping recessing parts 25, 26. Reinforcing cloth 27 is held in the inner mold 21 and misregistration is not caused. The inner mold 21 and an outer mold 22 are clamped and resin for molding is introduced from an introduction hole 22a. After resin is solidified, the molds are opened to take out the semifabricated product 4' of a bag cover 4. The part correspondent to a first projecting part 23 is formed into a thin-walled weakening line 4W. Reinforcing cloth 27 is exposed in the 4W part in a pitch interval of a first stopping recessed part 25. The bag cover 4 being a final product is obtained by cutting the reinforcing cloth 27 exposed in the weakening line 4W.
