[0002] Wear-resistant steel balls are a consumable auxiliary product in industrial crushing, also known as wear-resistant media for grinders. They are mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industry and other fields. Cast wear-resistant balls are made by pouring the raw materials into a mold, cooling them to obtain a workpiece with the wear-resistant balls and the edge materials as one, then separating the wear-resistant balls from the edge materials, and finally finishing the wear-resistant balls.

[0003] At present, the forging of wear-resistant balls usually places several molds in a row in an open place, and then manually pushes the casting tool filled with molten raw materials to cast the raw materials into each mold. After the raw materials in the mold are cooled and formed, the worker holds a hook-shaped tool and inserts it into the preset hole in the upper mold part of the mold, lifts the upper mold part and separates it under the dead weight of the lower mold. The molded workpiece is located in the lower mold part, and finally the lower mold part is flipped up to take out the workpiece. However, since the molded workpiece will act on the upper and lower molds of the mold, the worker hooks the upper mold part to lift it so that the lower mold part is separated, which is greatly hindered. The whole mold may be lifted multiple times by its own weight, and the lower mold part falls off, making it inconvenient to separate the whole mold. Utility Model Content

A molding cavity connected to the runner is provided on the opposite side of the upper mold cover 11 and the lower mold base 12.

[0035] The molten raw material is cast into the above-mentioned mold body 1 to form a workpiece. The raw material enters into the feed trough from the feed port of the upper mold cover 11, which is located between the upper mold cover 11 and the lower mold base 12, and then flows into the molding cavity composed of the upper and lower molds through the runner gate. When the raw material rises at the feed port, the injection is stopped and the internal raw material is allowed to be formed.

[0036] It should be noted that the mold body 1 is generally a columnar structure, the upper mold cover 11 is designed to be convex, and the lower mold base 12 is provided with a recessed part, which is adapted to the convex part of the upper mold cover 11, and the runner and molding cavity used for molding are components after the upper mold cover 11 and the lower mold base 12 are combined, and the runner and the molding cavity are half distributed on the convex part and the recessed part, and the upper mold cover 11 and the lower mold base 12 are based on a columnar structure, and the cross-sections of the convex part and the recessed part are both circular surfaces. The runner can be distributed in a ring according to the circular area to ensure that the molding cavities are equidistantly spaced between the runners, so as to realize batch molding of wear-resistant balls, and the connection between the runner and the feed trough and the feed port constitutes a gate, and the raw materials are injected into the runner at the same time for molding, which can improve the molding efficiency of the wear-resistant balls.

[0037] See also Figure 1-4 The connecting base 2 includes a connecting column 21 arranged on the lower mold base 12, and a chassis 22 is arranged on the connecting column 21. The mounting member 31 includes an inner connecting ring 311 and an outer mounting ring 312. The inner connecting ring 311 is arranged on the connecting column 21, and the inner connecting ring 311 is located between the chassis 22 and the lower mold base 12. The outer mounting ring 312 is arranged on the inner connecting ring 311.

[0038] Based on the split mold part 32, the upper mold cover 11 is operated with the lower mold base 12 as the reference. Through the threaded connection between the connecting column 21 and the chassis 22, the mounting part 31 can be sleeved on the connecting column 21 through the inner connecting ring 311 and installed on the bottom of the lower mold base 12, and then fixed by the chassis 22. Finally, the outer mounting ring 312 which is larger than the diameter of the lower mold base 12 is set as an outer ring on the lower mold base 12, and the split mold part 32 is set outside the lower mold base 12, and one end is connected to the upper mold cover 11.

[0039] See also Figure 1-4 The split module 32 includes a rotating part 321, a driving part 322 and a lifting part 323. The rotating part 321 is arranged on the outer mounting ring 312. The driving part 322 and the lifting part 323 are respectively arranged at two ends of the rotating part 321. A socket is opened on the upper mold cover 11, and one end of the lifting part 323 extends into the socket.

[0040] The split mold part 32 is arranged between the upper mold cover 11 and the lower mold base 12 through the mounting part 31, and the rotating part 321 is driven to rotate on the outer mounting ring 312 by applying force to the driving part 322, so that the lifting part 323 moves upward in the socket, pushing the upper mold cover 11 and the lower mold base 12 to separate.

[0041] It should be noted that the socket is arranged at the connection end between the upper mold cover 11 and the lower mold base 12, the driving part 322 adopts a pedal structure design, and the rotating part 321 acts as a rotating arm component between the driving part 322 and the lifting part 323, driving the lifting part 323 to move upward.

[0042] Considering that the wear-resistant balls and the edge material are integrally formed, the length of the edge material formed at the feed port cannot be controlled. Therefore, in this embodiment, the upper mold cover 11 is symmetrically provided with draw buckles located outside the lifting part 323, and the draw buckles can be inserted through the workpiece by manual intervention to pull up and separate the upper mold cover 11.
