Embodiment 1
[0060] A kind of alloy mold manufacturing process, comprises the following steps:
[0061] Step S1: select polystyrene foam 1, and process the upper model surface 1A of the target blank film on foam 1;
[0062] Specifically, the processing of the upper model surface 1A is obtained by CNC machining center, and the size of the entire upper model surface 1A has a certain machining allowance, such as figure 1 shown.
[0063] Step S2: Apply a release agent on the surface of the upper model surface 1A to form a release isolation layer;
[0064] Specifically, the foam is polystyrene foam, and the density of the foam is ≥20kg / m 3 , the density of foam is 28kg / m in the present embodiment 3 . This high-density foam can ensure the strength of the foam and avoid deformation during mold casting.
[0065] The mold release agent is sprayed on the foam 1, and the mold release agent solidifies to form a mold release isolation layer, which can be effectively separated from the subsequent c...

[0117] 6 parts of Ti, 3 parts of 2000 mesh iron oxide powder, 1 part of 1200 mesh iron oxide powder, 3 parts of 1600 mesh electrolytic iron powder, 1 part of 1600 mesh reduced iron powder, 3 parts of 800 mesh reduced iron powder, 3 parts of 600 mesh carbon black , 4 parts of Cr, 3 parts of Mn, 5 parts of Mg, 1 part of Zn, 1 part of Wc, 1.5 parts of Al and 3 parts of ceramic powder,
[0118] 5 parts of graphene resin solution, wherein, 2 parts of graphene dispersion liquid are selected from the graphene resin solution to be prepared with 90 parts of epoxy resin.
[0119] The second optional implementation mode: the metal-based polymer material includes 10...
Embodiment 2
[0177] Such as Figure 4 As shown, a mold includes a structural layer 5 and a post-cured mold base 6, the structural layer 5 is arranged in the mold frame 3, the upper end of the post-cured mold base 6 has a mold cavity, and the bottom of the post-cured mold base 6 is provided with a support A column, a pouring hole 42 is opened in the structural layer 5, the post-cured mold base 6 rests on the structural layer 5, and the supporting column is inserted into the pouring hole 42.
[0178] In this mould, the structural layer 5 guarantees the strength and stably supports the post-cured mold base 6. The post-cured mold base 6 is made of the above-mentioned metal-based polymer composite material to ensure hardness, strength, low shrinkage and corrosion resistance.
