PURPOSE:To facilitate satisfactory resin molding meeting various manufacturing conditions by limiting sealing resin injected onto one of main surfaces of a supporting plate from a resin injection inlet linked with a molding cavity by sliding dies. CONSTITUTION:Sliding dies 16, 17 and 18 are made to protrude into a molding cavity 25 to limit sealing resin injected onto one of main surfaces of a supporting plate 2 from a resin injection inlet linked with the molding cavity 25. Therefore, the flow of the sealing resin flowing on the one main surface side of the supporting plate 2 is relatively intensified compared to the flow of the sealing resin flowing on the other main surface side of the supporting plate 2. As a result, the resin flowing on the one main surface side of the supporting plate 2 and the resin flowing on the other main surface side of the supporting plate 2 are well balanced and satisfactory resin molding can be performed. Further, as the sliding dies 16, 17 and 18 can be advanced into and retreated from the molding cavity 25, the timing and speed of the movement of the sliding dies can be arbitrarily predetermined. With this constitution, satisfactory resin molding can be performed under various manufacturing conditions. |
