Title:
COMPRESSION MOLDING METHOD FOR I-SHAPED PART
Document Type and Number:
WIPO Patent Application WO/2021/057485
Kind Code:
A1
Abstract:
A compression molding method for an I-shaped part (1) without machining, and with high generation efficiency and no waste of raw materials. The I-shaped part (1) comprises an intermediate shaft (11), an upper wing plate (12), and a lower wing plate (13). A molding die comprises an outer mold (2), an upper pressure plate (3), a lower pressure plate (4), a Huff mold (5), an upper mold (6), and a lower mold (7). The upper pressure plate (3), the Huff mold (5), and the lower pressure plate (4) are vertically arranged in the outer mold (2) at intervals. The upper mold (6) extends into the upper pressure plate (3). The lower mold (7) extends into the lower pressure plate (4). The outer mold (2), the upper mold (6), the upper pressure plate (3), the Huff mold (5), the lower pressure plate (4), and the lower mold (7) enclose a mold cavity (9). The compression molding steps comprise: filling the mold cavity (9) with a raw material (10); when the outer mold (2), the upper pressure plate (3), and the lower pressure plate (4) are all maintained stationary, moving the upper mold (6) downward and moving the lower mold (7) upward until a lower surface of the upper mold (6) and an upper surface of the lower mold (7) are respectively flush with a lower surface of the upper pressure plate (3) and an upper surface of the lower pressure plate (4); and when the outer mold (2) is maintained stationary, moving the upper mold (6) and the upper pressure plate (3) downward, and moving the lower mold (7) and the lower pressure plate (4) upward to reach the required size of the I-shaped part (1).
