[0015] The lower die assembly 1 includes a lower die base 101 and a die 102, and the inside of the die 102 is provided with a cooling water channel running through along the length direction. The convex die 202 is adapted and clamped with the die 102, and the bottom of the die 102 is fixedly installed with the lower die base 101. The lower die base 101 is provided with a plurality of two-axis linear modules 104 distributed along the edge contour of the die 102, and the end of the two-axis linear modules 104 is provided with an edge wrapping die 103, and the plurality of edge wrapping die 103 are arranged along the length direction of the contour of the die 102. When the edge wrapping die 103 moves outward synchronously, the die cavity of the die 102 can be opened. The lower mold base 101 is a rectangular plate structure and buffer cylinders are fixedly installed at the four corners of the upper part. The buffer cylinders play a role in reducing impact when the mold is closed. A middle layer heating assembly 3 is installed between the two groups of buffer cylinders opposite to each other on the left and right. End molds 105 are provided at both ends of the concave mold 102. The end mold 105 is driven by a cylinder located at its outer end. The two-axis linear module 104 includes two vertically arranged cylinders. The two-axis linear module 104 can drive the corresponding edging mold 103 to move vertically and longitudinally.
