in the process of the step, silicon rubber mold cores can be manufactured in batches, so that the wax molds can be manufactured conveniently, the mold cores are directly placed and wax is injected after female molds are cleaned, and the efficiency of manufacturing the wax molds is improved.
Step four, preparing a synthetic wax material for pouring, wherein the synthetic wax material consists of the following raw materials in percentage by mass: 85% of paraffin, 10% of rosin, 3% of montan wax and 2% of low molecular polyethylene; mixing the above materials, stirring, heating to 80-95 deg.C, stirring for 5min, stirring thoroughly and uniformly to obtain paste;
step five, uniformly coating 1-1.5mm of the synthetic wax material on the surface of the silicon rubber mold core, and then assembling the mold core in a female mold;
heating the synthetic wax material to 120 ℃, pouring the synthetic wax material into a cavity formed by a silicon rubber female die and a die core, putting the cavity into a vacuum chamber, and vacuumizing for 2-3min under the pressure of-0.8 MPa; after the vacuum is relieved and the synthetic wax material is solidified, demolding to obtain the wax mold with the silicon rubber mold core;
and seventhly, cleaning the water and wax chips of the female die, putting the female die into a silicon rubber die core, smearing the synthetic wax material, and injecting wax again.
Preferably, in step five, the mold core is clamped in the female mold by using a positioning pin.
Preferably, the low molecular weight polyethylene is low molecular weight polyethylene with a density of 0.9.
The invention has the beneficial effects that: 1. the wax material is molded by one-time casting, so that the casting times are reduced, and the molding speed of the wax mold is improved; 2. the statue prototype rollover adopts 20-degree silicone rubber, so that the flexibility is good; 3. in order to effectively reduce the deformation of the wax mould, the mould core is made of 50-degree silicon rubber, and the mould core is not deformed in the subsequent vacuum pumping treatment, so that the forming rate of the wax mould is effectively ensured; 4. the components of the synthetic wax are reasonably proportioned, the shrinkage rate of the wax mould is reduced, the surface smoothness of the wax mould is improved, the forming thicknesses of the female mould, the mould core and the wax mould are accurately controlled, and a layer of synthetic wax is coated on the mould core before casting, so that the temperature of casting the synthetic wax is reduced, and the shrinkage is reduced.
