[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A scraper structure of an impeller mold includes a lower mold and an upper mold, the upper mold is rotatably connected to the top of the lower mold, the top of the lower mold is provided with a cavity, the bottom inner wall of the cavity is provided with multiple blade grooves, blade punches are clamped in the blade grooves, the bottom inner wall of the cavity is fixedly connected with a boss, the top of the upper mold is provided with a runner hole, the top of the upper mold is provided with multiple overflow holes, the top of the boss is rotatably connected with a positioning column, the positioning column passes through the runner hole, the top of the positioning column is clamped with a pin, one side of the pin is fixedly connected to the scraper, and the scraper is fixedly plugged into the top of the upper mold.

[0007] Furthermore, a plurality of first reinforcing ribs are fixedly connected to the bottom outer wall of the lower mold.

[0008] Furthermore, a plurality of second reinforcing ribs are fixedly connected to the upper surface of the upper mold.

[0009] Furthermore, a plurality of blade convex molds are arranged around the boss.

[0010] Furthermore, the scraper is a Z-shaped structure.

[0011] The beneficial effects of the utility model are:

[0012] 1. By rotating the upper mold, the scraper is driven to rotate, thereby scraping the top of the injection liquid in the cavity flat, thereby avoiding the roughness of the workpiece surface and improving the demoulding quality of the workpiece.

[0013] 2. The provision of the first reinforcing rib and the second reinforcing rib can strengthen the firmness of the lower mold and the upper mold, thereby extending the service life of the impeller mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 3 A scraper structure of an impeller mold includes a lower mold 1 and an upper mold 2. The upper mold 2 is rotatably connected to the top of the lower mold 1. The top of the lower mold 1 is provided with a cavity 101. The bottom inner wall of the cavity 101 is provided with a plurality of blade grooves 102. The blade grooves 102 are clamped with blade punches 3. The design of the blade punch 3 allows the injection molding liquid to form a blade structure. The bottom inner wall of the cavity 101 is integrally formed with a boss 103. The top of the upper mold 2 is provided with a runner hole 201. The top of the upper mold 2 The top of the boss 103 is rotatably connected to a positioning column 4, which passes through the runner hole 201 so that the injection liquid can be injected into the cavity 101 from the runner hole 201. A bayonet 5 is clamped on the top of the positioning column 4, and a scraper 6 is integrally formed on one side of the bayonet 5. The scraper 6 is fixedly plugged into the top of the upper mold. The scraper 6 is rotated by rotating the upper mold 2, thereby scraping the injection liquid in the cavity 101 flat.

[0020] The bottom outer wall of the lower mold 1 is integrally formed with a plurality of first reinforcing ribs 104, which strengthen the firmness of the lower mold 1. The upper surface of the upper mold 2 is integrally formed with a plurality of second reinforcing ribs 202, which strengthen the firmness of the upper mold 2. A plurality of blade punches 3 are arranged around the boss 103, and the scraper 6 is a Z-shaped structure.

[0021] The working principle of this embodiment is as follows: when in use, first, the molding liquid is injected into the cavity 101 from the runner hole 201, and then the excess molding liquid is discharged from the overflow hole 203. Then, the scraper 6 is driven to rotate by rotating the upper mold 2, thereby scraping the top of the molding liquid in the cavity 101 flat, and at the same time, the bubbles in the molding liquid are discharged from the overflow hole 203.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
