[0006] Optionally, the flow channel core box mold is provided with a groove, and the size of the convex surface is matched with the size of the inner cavity of the groove.

[0007] Optionally, the bottom of the movable block I and the top of the movable block II are respectively V-shaped and in contact.

[0008] Optionally, the adhesion agent is Kraft glue.

[0009] Compared with the prior art, the utility model has the beneficial effects as follows:

[0010] This utility model provides an integrated device for the flow channel core box movable blocks through the above-described technical solution. An adhesive is applied between the bottom of movable block I and the top of movable block II for a fixed connection. The movable blocks are embedded in the flow channel core box mold and cured by heating, thus fixing movable block I and movable block II together, greatly improving the stability between the two movable blocks. Through the bonding and curing of the movable block assembly, the movable blocks are easy to install during core making in the workshop, improving installation efficiency. During sand core making, the positioning effect of the movable block tongue is good, and defects such as misalignment of the movable blocks and loose or missing blocks are significantly improved. The integrated design reduces the difficulty and cost of mold debugging to a certain extent, and the cooperation between the two movable blocks and the flow channel core box mold is simpler, greatly reducing the probability of problems.
