Solution of the present invention is that correspondence is set up one group of internal mold on the basis of adopting one group of external mold (face mould), make the cavity that forms people, thing housing between the inside and outside mould, adopting crystal resin to annotate (filling) then goes in the cavity body of mould, wait to solidify take out the back and with each respectively the decomposition housing of moulding by casting piece together global shape, splicing place is still adopted and the resin of pouring into a mould the housing same recipe is made adhesive it is bonded into one, thereby realizes its purpose.Therefore, the inventive method comprises:

A. make outer module: the form of making human body, object by drawing up adopts the sculpture clay sculpture shaping, then on the clay sculpture surface by the conventional method coated with resins and lay glass cloth to turn over the fiberglass external mold (face mould) of making this clay sculpture, again its decomposition to be cut into the outer module group of being convenient to the demoulding after solidifying, and the module line of cut applies or the fixed edge that bonds outside each, and is stand-by;

B. make inner module: make through the A operation each outside the module inwall be close to one deck plasticine or sculpture clay book sheet respectively, the sheet body thickness is identical with plan production thickness of shell, and after releasing agent is coated in sheet surface and outer module fixed edge inboard, coated with resins and lay glass cloth again, treat that it solidifies the back and takes out as inner module group of being with fixed edge stand-by;

C. assembly jig: will through A, B operation respectively outside each of moulding, inner module is fitted to the mould of band die cavity by the fixed edge correspondence, and is and at the default pore in the bottom of each die cavity, stand-by;

D. allocate resin and cast: place crystal resin in the agitator and add the reinforcing agent of weight resin 3～6wt% and 0～0.3wt% fiberglass with mill base, mix, the curing agent that adds weight resin 1～4wt% again mixes the back, it is injected respectively in each mould of C operation assembling immediately, after vibrations, leaving standstill curing, remove inside and outside module and promptly get and respectively decompose housing;

E. bonding forming: adopt by the prescription of D operation and the resin of method allotment and make binding agent, respectively decompose case bonding and become complete body, solidify back polishing interface and get final product with obtained.

Above-mentioned crystal resin is adjacent benzene type (class) crystal resin; And described reinforcing agent is cobalt green or acid resistant cobalt; And curing agent is potassium peroxide ethyl ketone or cyclohexanone.

The present invention adopts the material identical with watering the material feeding composition that each block of decomposition bonding is combined into one at last owing to adopt crystal resin directly to pour into the object block of decomposition as primary raw material and by mould again.Thereby it is high and even to have transparency, establish under the light source irradiation interior, no network-like and interface lines, appearance tactile impression is strong, and intensity height, ageing-resistant and adopt die casting moulding, productivity ratio height, operating personnel's technological literacy is required characteristics such as relatively low.
