[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a casting sand core assembly mold, including a mold mainboard, a linear slide set is provided on the mold mainboard, slider a and slider b are opened into position through the linear slide set, slider a screw limit contacts with slider a opened into position bumper, slider b contacts with slider b opened into position bumper, slider b limit gate contact with slider b limit gate locking limit, before assembling the sand core, slider b limit gate contact with slider b limit gate opening limit, slider a limit gate rotates and contacts with slider a limit gate locking limit, slider b closed into position limit block contacts with slider b limit bumper, slider b limit gate rotates and contacts with slider b limit gate locking limit, and limit bumper a contacts with limit bumper c.

[0006] Preferably, the a slider and b slider are respectively 4 groups, which are evenly distributed on the mold main board.

[0007] Preferably, the jig mainboard is connected to the trolley via jig and trolley positioning pins.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: by using this mold, production efficiency is improved, quality is improved, coating is convenient and quick, labor is saved, and better economic benefits are brought to the enterprise.
