The all parts needed for mould are installed to corresponding position first, the knob of thickness adjusting apparatus, control wedge shape is adjusted
Moving forward and backward for block, so as to control the gap between mould and lower mould, the size in gap is measured by measurement apparatus, until reaching
Untill required gap；Releasing agent is applied on upper/lower die inner surface and sealing strip, then ready prepreg is laid on
In lower mould, sealing strip is loaded in seal groove；Then upper mould is merged with lower mould, mould is integrally finally positioned over extrusion press
On workbench, start extrusion press, control pressure 2Mpa.Intensification 30min reaches 120 °C of temperature needed for shaping, after reaching 120 °C
Heat-insulation pressure keeping 90min, then naturally cools to 45 °C, and product is taken out in the last demoulding.
Positive effect of the invention is：A kind of hot compression molding mould for preparing different-thickness hat front longitudinal
And preparation method thereof solve the problems, such as hat front longitudinal rapid, high volume the manufacturing；Solve single hat front longitudinal heat
Molding production mould can only prepare the problem of single thickness product.
