Casting is a process method of pouring molten metal or non-metallic material into a mold, and after cooling and solidification, the product of the required shape and size is formed. The mold core, as the core part of the mold, is mainly used to form the cavity or complex structure inside the casting. The mold core can ensure the accuracy and integrity of the internal structure of the casting. It not only can keep the external shape of the casting from changing greatly, but also can provide necessary support and positioning when the metal liquid cools and solidifies, preventing the casting from deforming or producing defects. However, the tool structure for making tire rolling mold cores is complex, and when sand casting is performed, the two half core shells are not well fixed, which makes it easy for gaps to form between the core shells, causing the core shell to fall off and making it difficult to disassemble, resulting in the problem of gaps in the mold core after forming.

[0019] The utility model discloses a kind of tire rolling mould core manufacturing devices, the following specific description is made to one embodiment of the utility model in conjunction with drawings.
[0020] As Figure 1As shown, the tire rolling mold core making device comprises a first core shell 1, a second core shell 2 and a clamp 3. The cross sections of the first core shell 1 and the second core shell 2 are both semicircular. The first core shell 1 and the second core shell 2 are hingedly connected by a hinge 4 to form a circular tube structure. The other side of the first core shell 1 outwardly protrudes a first lug 5 adjacent to the edge of the first core shell 1. The other side of the second core shell 2 outwardly protrudes a second lug 6 adjacent to the edge of the first core shell 1. The outer sides of the first lug 5 and the second lug 6 are both provided with a fixing groove 12, and the first lug 5 and the second lug 6 are detachably fixedly connected by the clamp 3.
[0021] In combination Figure 2 and Figure 3 As shown, the clamp 3 is approximately U-shaped, one side end of the clamp 3 inwardly protrudes to form an abutting portion 7, and the other side end is fixedly connected with a connecting portion 9. The connecting portion 9 is circular tube-shaped, the inner wall is provided with threads, and the connecting portion 9 is configured with a pressing rod with an outer wall provided with threads, and the outer end of the pressing rod is fixedly connected with a rotating handle 11. The inner end of the abutting portion 7 is fixedly connected with a first clamping block 8, and the end of the pressing rod is rotatably connected with a second clamping block 10, and the first clamping block 8 and the second clamping block 10 are both matched with the fixing groove 12. The second clamping block 10 is fixedly connected with a sleeve, and the side wall of the sleeve is provided with a through hole. The end of the pressing rod passes through the through hole and extends into the sleeve, and the edge of the end of the pressing rod outwardly extends to form a protruding edge, which is used to prevent the end of the pressing rod from being separated from the sleeve.
[0022] In use, the operator rotates the first core shell 1 and the second core shell 2 through the hinge 4 to form a circular tube structure, places the first clamping block 8 of the abutting portion 7 in the fixing groove 12 of the first core shell 1, then places the second clamping block 10 of the pressing rod in the fixing groove 12 of the second core shell 2, rotates the rotating handle 11 of the pressing rod to make the end of the pressing rod move along the sleeve, the end of the pressing rod gradually approaches the second clamping block 10 and presses the second clamping block 10 to fasten, and finally the core is made through subsequent operations. The fixing groove 12 can limit the movement of the first clamping block 8 and the second clamping block 10, avoid the clamp 3 from being separated from the first lug 5 and the second lug 6 in the case that the fastening force of the clamp 3 is insufficient, and facilitate use. When the core needs to be detached from the first core shell 1 and the second core shell 2 after the core is made, first rotate the rotating handle 11 at the outer end of the pressing rod to gradually separate the second clamping block 10 from the fixing groove 12 on the second lug 6, adjust the distance between the first clamping block 8 and the second clamping block 10 to an appropriate distance, then take off the clamp 3 from the first core shell 1 and the second core shell 2, and then smoothly take out the core.
