The first sliding hole 411 and the second sliding hole 412 in the embodiment are arranged in the movement stroke of the first partition plate 71 and the second partition plate 72 respectively, so that the machine-made sand will not flow out in the movement process of the first partition plate 71 and the second partition plate 72.
