Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0028] Please refer to Figures 1-9 In the embodiments of the present application, an impeller rotating mold structure comprises a base 11, a lower mold plate 2 and an upper mold plate 3, a mold core 5 is arranged between the lower mold plate 2 and the upper mold plate 3, two outer mold cores 4 are arranged outside the mold core 5, a top plate 10 and a bottom plate 9 are arranged at the top end and the bottom end of the mold core 5 respectively; two guide blocks 6 are mounted at the bottom end of the lower mold plate 2, guide rods 12 cooperating with the guide blocks 6 are arranged on both sides of the base 11, the guide blocks 6 are provided with guide grooves 601, the guide grooves 601 are arranged obliquely, and the guide grooves 601 of the two guide blocks 6 have the same rotation direction along the rotation direction; the lower mold plate drives the overall movement of the support seat, the guide blocks and other components, the guide rods on the base are embedded in the oblique guide grooves of the guide blocks; as the lower mold plate continues to move, the cooperation of the guide rods and the oblique guide grooves forces the guide blocks to drive the rotation of the lower mold plate and the mold core assembly, and the two outer mold cores gradually separate from the formed impeller along the rotation action.

[0029] The support seat 1 is mounted at the bottom end of the lower mold plate 2, the guide blocks 6 penetrate through the support seat 1, and the guide blocks 6 and the lower mold plate 2 are fixed by bolts.

[0030] Limiting rods 8 are arranged on both sides of the base 11, three limiting rods 8 are arranged on each side of the base 11, and the base 11 is arranged as a cutting plane structure at the limiting rods 8; the center column 7 extends into the inside of the mold core 5.

[0031] The working principle of the present application is that the upper die plate and the lower die plate are closed, the mold core, the two outer mold cores, the top plate, the bottom plate and the center column jointly constitute a complete impeller injection molding cavity, and the molten raw material is injected into the cavity and then cooled and formed.

[0032] When the demolding starts, the lower die plate drives the support seat, the guide block and other components to move as a whole, and the guide rod on the base is embedded in the inclined guide slot of the guide block.

[0033] With the continuous movement of the lower die plate, the cooperation of the guide rod and the inclined guide slot forces the guide block to drive the lower die plate and the mold core assembly to rotate, and the two outer mold cores are gradually separated from the molded impeller with the rotating action.

[0034] When the lower die plate moves to the limit rod, the limit rod limits its further displacement, at this time the impeller has completely separated from the mold core and the outer mold core, and the demolding process is completed, and the subsequent impeller taking operation can be performed.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or replace some technical features with equivalent ones.
