The prompt
A vertical RCC pipe with HDPE inner lining making machine, has collapsible inner mold a Develop a dimensioned hydraulic collapsible inner mould design for a vertical HDPE-lined RCC pipe machine using these inputs: pipe internal diameter = 1524 mm; HDPE liner thickness = 3 mm; pipe length = 2440 mm; actuation = hydraulic; Include wedge geometry, hydraulic cylinder sizing methodology, radial guides, locking, extraction clearance, and engineering drawings. Generate a python file to make 3d step file of the mechanism. get inspiration from the attached is patent. inner mold outer dia 1524 mm, height 8ft. generate full assembly 3d step drawing python script. collapsed dia will be 1500 mm and the extended dia is 1524 mm.
