1. high rigidity, a high-intensity resin mould making method, is characterized in that:

  • comprise the following steps;

    Step one, makes former;

    utilize Product Process figure to build threedimensional model, recycles this model and prepares a corresponding with it die and be former, be ensure female mold surfaces roughness requirements, need at former inner surface smearing release agent, as varnish, wax;

    The female mold surfaces surface smear 3-5mm high-intensity resin layer prepared;

    Step 2, make aluminium skeleton;

    utilize the threedimensional model built in above-mentioned steps one, model outer profile size is reduced 3-5mm, this is the moulded dimension made needed for aluminium skeleton, according to this size design aluminium skeleton structure model, and aluminium skeleton pattern is designed to the structure that 8-10mm wall thickness inside is hollow, then first process equal proportion evaporative pattern (EPC) according to the aluminium skeleton pattern of above-mentioned design, finally namely evaporative pattern cast aluminium is obtained aluminium skeleton;

    Step 3, installs aluminium skeleton;

    the pressing of aluminium skeleton be combined with the high-intensity resin layer of female mold surfaces, make planes align on face, aluminium skeleton upper surface and former;

    Step 4, removes former;

    after resin bed bone dry, removes former, obtains the bond of high-intensity resin layer and aluminium skeleton, be mould.
