[0028] This embodiment provides a sand casting composite core for a tire-type roller sleeve, comprising an outer mold cavity body and a cavity located in the outer mold cavity body, wherein a core is installed in the cavity, and the core is composed of a plurality of modules combined and spliced.
[0029] The sand casting mold of the tire type roller sleeve of the utility model is realized by splitting the core into multiple modules, placing the multiple modules in the mold cavity respectively, and combining and splicing them into a complete core structure, which facilitates the placement of the core, improves the efficiency and reduces the cost. Example

[0031] In this embodiment, the core is formed by combining and splicing at least three modules.
[0032] In this embodiment, preferably, Figure 5 and Figure 6 As shown, the core is composed of five modules 3. The complete core structure is divided into five modules, and then each module 3 is placed in the cavity in turn (such as Figure 7 This perfectly solves the problem that the original tire core cannot be placed in the mold cavity.
[0033] In this embodiment, the core has a cavity formed by a casting channel, and the cavity structure size is the same as that of the roller sleeve. Finally, the cavity formed by the casting channel is cast into a tire-type roller sleeve structure. Example

[0036] In this embodiment, preferably, Figure 5 and Figure 6 As shown, the core is composed of five modules 3. The complete core structure is divided into five modules, and then each module 3 is placed in the cavity in turn. A positioning core head is provided below the core, and a positioning hole is provided below the outer mold. When the core is placed in the outer mold cavity, the positioning core head below is close to the edge of the positioning hole, as shown in FIG. Figure 6 As shown, first put in two modules A and make the lower positioning core head close to the outer mold positioning hole edge, then put in two modules B with the lower positioning core head close to the outer mold positioning hole edge, and finally insert module C. In this way, the combination is placed in the cavity, as shown in the figure. Figure 7 This perfectly solves the problem that the original tire-type core cannot be put into the mold cavity.

[0038] In this embodiment, preferably, a heat dissipation mechanism is provided inside the core, and the heat dissipation mechanism adopts internal heat dissipation or external circulation heat dissipation.
[0039] Among them, internal heat dissipation can be achieved by using structures such as heat dissipation holes.
