Drawings
Fig. 1 is a schematic view of an expansion mold for integrally molding a composite material shading cylinder seat.
Detailed Description
The used integrated into one piece mould of shaping includes: the upper positioning pressing plate 200, the lower positioning pressing plate 300, the plurality of metal surrounding strips 410 and 420, the plurality of metal core blocks 510 and 520 and the plurality of expansion rubber core block assemblies 610 and 620 are integrally cured and molded into the composite material shading cylinder base 100 by adopting a die pressing process.
Referring to fig. 1, the expanded rubber core block assemblies 610 and 620 are coated with a plurality of layers of carbon fiber prepregs, and are positioned on the upper positioning pressing plate 200 through positioning pin screws, and then the plurality of layers of carbon fiber prepregs are coated integrally. The prepregs at the positions of the metal core blocks 510 and 520 are turned up by staggered layer cutting.
The metal surrounding strips 410 and 420 are pressed by a mould press, the surrounding strips move to the center, and after the surrounding strips are in place, the surrounding strips are positioned and fixed on the upper positioning pressure plate 200 by using pin screws. Some of the metal core blocks 510, 520 are then positioned and mounted on the upper positioning platen 200, and the remaining blocks are pressed into place by a die press after being mounted.
And finally, after the lower positioning pressing plate 300 is installed, placing the lower positioning pressing plate on a molding press for hot pressing and curing, wherein the pressure of the molding press is 5-7MPa, the heating temperature is 176 ℃, the temperature is kept for 3h, and the silicon rubber expands and deforms under the hot pressing condition, so that the reinforcing ribs in the shading cylinder seat are laterally pressed.
