Embodiment 1

[0061] A combined mould, comprising a follow-up die 10, a support die 20 and a riveting rod 30, the follow-up die 10 includes a main body 11, a reinforcement layer 12, a working surface 13 and an assembly face 14, the main body 11 is formed by pressing or printing granular materials The reinforcement layer 12 is arranged on the surface of the main body 11, or the reinforcement layer 12 penetrates into the surface of the main body 11. The side of the main body 11 in contact with the sand mold cavity is the working surface 13, and the opposite side is the assembly surface 14. The support mold 20 is installed on the main body 11. One side of the assembly surface 14, and the shape matches the shape of the assembly surface 14, because some of the molds are used to form the external structure of the casting such as attached Figure 10-13 As shown, some are to form the inner cavity structure of the casting as attached Figure 1-9 As shown, so there will be differences, but in a word,...

Embodiment 2

[0070] On the basis of embodiment 1, with reference to the attached Figure 3-6 As shown, the main body 11 also includes reinforcing ribs 113, the main body 11 is made of double layers, the main body 11 is a double or multi-layer sandwich with a cavity, and a reinforcing rib 113 is arranged between the two-layer structure, the described Both ends of the reinforcing rib 113 are respectively connected to the two-layer structure, and the double or multiple layers are integrally formed with the reinforcing rib 113 . The wall thickness of each layer is 20-50 mm. The spacing of the ribs 113 is 100-300 mm.

[0071]After the main body 11 is made into two or more layers, the reinforcement layer 12 is adhered or infiltrated on the surface to obtain the follow-up mold 10, which reduces the quality of the main body 11 and increases the area of ​​the reinforcement layer 12, thus improving the strength of the follow-up mold 10. The overall hardness and tensile strength can obtain a confor...

Embodiment 3

[0073] On the basis of Embodiment 1 or Embodiment 2, the main body 11 includes a splicing body 110, a connecting block 111, and a slot 112. The main body 11 is formed by splicing at least two splicing bodies 110; Two adjacent splicing bodies 110 are connected, and at least two splicing bodies 110 are relatively fixed. Adjacent splicing bodies 110 are respectively provided with matching protruding or recessed slots 112 , that is, the adjacent splicing bodies 110 are spliced ​​and formed by placing the protrusions in the recesses.

[0074] Refer to attached figure 1 And attached image 3 As shown, the adjacent splicing bodies 110 are connected together by connecting blocks 111 or card slots 112, so that the splicing bodies 110 become a whole. Generally, the butterfly-shaped or flower-shaped connecting blocks 111 are arranged horizontally, and the splicing bodies 110 are connected vertically. On the straight side, the splicing body 110 is connected to the splicing body 110 thro...

Abstract

The invention relates to a combined mold which comprises a shape follow-up mold and a supporting mold. The shape follow-up mold comprises a main body, a reinforcing layer, a working surface and an assembling surface, the main body is formed by pressing or printing granular materials, a reinforcing layer is arranged on the surface of the main body, or the reinforcing layer permeates into the surface of the main body, the surface, in contact with a sand mold cavity, of the main body is a working surface, the other opposite surface is the assembling surface, and the supporting mold is mounted onone side of the assembling surface of the main body and matched with the assembling surface in shape. A particle material convenient to form is used for printing or pressing to form the shape follow-up mold, the advantage that the particle materials are convenient to form is utilized, the defect that the particle materials are insufficient in hardness is overcome through the reinforcing layer withhigh tensile strength and hardness, the supporting mold serves as a filling material, and therefore the problems of the overall tensile strength and hardness are solved; and meanwhile, the overall mass can be light, and therefore the combined mold which makes up for the defects and integrates all the advantages is obtained.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a composite mold. Background technique [0002] The bottleneck of new products in the foundry industry lies in the development of molds. The speed of mold development determines the length of the development cycle of new products. Existing molds have their own advantages and disadvantages. Traditional wooden molds are low in cost and can be used repeatedly, but the development cycle is long, especially complex. The castings are more difficult to make and the repeatability is not good; the traditional lost foam is low in cost and needs to be machined and manufactured, but it cannot be used repeatedly; the traditional metal mold has a long production cycle and can be used repeatedly, but it is not suitable for large parts, and High cost; emerging FDM molds and SLA molds are all printed and molded, and the effect is good but the cost is too high. [0003] Therefore, shortenin...
