[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] Combined with Figure 1-2, an automatic positioning device for mold processing, comprising a lower support base 1, wherein the four corners of the top of the lower support base 1 are connected with fixed support columns 2, and the tops of the multiple fixed support columns 2 are commonly connected with a support top plate 3, and the middle of the support top plate 3 is connected with an electric cylinder 4, and the bottom power end of the electric cylinder 4 is connected with a lifting support plate 5, and the bottom is connected with a detachable plate 23, that is, the detachable plate 23 and the lifting support plate 5 can be fixedly connected and disassembled by bolts, and the bottom of the detachable plate 23 is connected with an upper mold 6 with an adjustable position, and the middle of the lower support base 1 is connected with a mold connecting base 7. The top of the mold connecting base 7 is connected with a lower mold 8, the middle of the detachable plate 23 is provided with a through hole 20, the bottom of the lifting support plate 5 is provided with a circular groove 19, the top of the upper mold 6 is connected with a supporting cylinder 21 that matches the through hole 20, and the top of the supporting cylinder 21 is connected with a disc 22 that matches the circular groove 19. The diameters of the through hole 20 and the circular groove 19 are slightly larger than those of the supporting cylinder 21 and the disc 22, so that the position of the upper mold 6 can be slightly adjusted. During normal installation, it is necessary to manually adjust the upper mold to align with the lower mold 8. The weight of the upper mold 6 itself will prevent the upper mold 6 from shaking easily.

[0016] The lower mold 8 is provided with limiting grooves 13 all around, and a support slider 14 is provided in the limiting groove 13 for limiting sliding.
