Description

Technical Field

[0001] This utility model relates to the field of high-temperature sintered ceramic ball forming mold technology, and in particular to high-temperature sintered ceramic ball forming mold. Background Technology

[0002] Ceramic balls, with their excellent properties such as high strength, high wear resistance, high temperature resistance, corrosion resistance, and insulation, have been widely used in many fields. For example, in the bearing industry, silicon nitride ceramic balls can improve the bearing's limiting speed, extend its service life, and maintain high precision, and are widely used in high-precision machine tools, aero engines, and other equipment. In the sealing field, ceramic balls can maintain good sealing performance in harsh environments. As the demand for high-performance ceramic balls continues to increase across industries, the requirements for their molding dies are also becoming increasingly stringent.

[0003] Early mold materials mostly used ordinary metals, but these were prone to wear and deformation under high temperature and high pressure molding conditions, affecting the molding quality of ceramic balls and the mold's lifespan. With the development of materials science, high-temperature resistant and wear-resistant alloy materials and hard alloys have gradually emerged, greatly improving mold performance and service life. However, during mold use, when ceramic balls adhere to the mold after molding, they need to be manually processed one by one, resulting in low molding efficiency. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0006] Preferably, guide holes are equidistantly provided around the lower mold, and buffer spring rods are installed opposite to each other around the upper mold at the upper end of the guide holes.

[0007] Preferably, electric telescopic rods are installed at opposite positions inside the lower mold and the upper mold, and push plates are fixedly connected to the telescopic ends of the electric telescopic rods. One end of each push plate is fixedly connected to a connecting post opposite to the mold opening on the lower mold and the upper mold.

[0008] Preferably, threaded grooves are provided at the top ends of the connecting columns, and the connecting columns are fixedly connected to the spherical molds through threaded connections. A Chinese character-shaped cavity is provided inside the connecting columns, and a T-shaped push rod is installed in the Chinese character-shaped cavity.

Barrier rings 6 are fixedly connected relatively between the die grooves 3 at the upper and lower ends of the spherical dies. Top material mechanisms are installed in both the lower die 1 and the upper die 4. Through the barrier ring 6 between the lower die 1 and the upper die 4, it is convenient to prevent burrs from appearing in the formation of ceramic balls; Guide holes 2 are equidistantly provided around the lower die 1, and buffer spring rods 5 are oppositely installed around the upper die 4 at the upper ends of the guide holes 2. Through the guide holes 2 and the buffer spring rods 5, it is convenient for the lower die 1 and the upper die 4 to be tightly abutted against each other; Electric telescopic rods 7 are oppositely installed at the intermediate positions inside the lower die 1 and the upper die 4. The telescopic ends of the electric telescopic rods 7 are fixedly connected with push plates 8. One ends of the push plates 8 are fixedly connected with connecting columns 10 opposite to the die openings provided on the lower die 1 and the upper die 4. Through the electric telescopic rods 7 and the push plates 8, it is convenient for the push plates 8 to push out the spherical dies, so that the connecting columns 10 and the spherical dies are connected to each other.

[0023] In the present invention, thread grooves are provided at the tops of the connecting columns 10, and the connecting columns 10 and the spherical dies are fixedly connected by threaded connections. A middle-shaped cavity is provided inside the connecting columns 10, and a T-shaped push rod 11 is installed in the middle-shaped cavity. One end of the T-shaped push rod 11 penetrates through the connecting column 10 and the spherical die. Through the T-shaped push rod 11, it is convenient to push out the ceramic balls in the spherical die from the die; Exhaust holes are provided in both the connecting columns 10 and the push plates 8, and the exhaust holes are connected to each other and commonly provided with an air inlet. Through the connecting columns 10 and the push plates 8, it is convenient to add gas to the inside; The top material mechanism includes an air pipe 12 fixedly connected to the air inlet, and the other end of the air pipe 12 is fixedly connected to an air pump 9.

[0024] Working principle: When using this utility model, firstly, the upper mold 4 and the lower mold 1 are aligned. Then, through the guide hole 2 and the buffer spring rod 5, the upper mold 4 and the lower mold 1 are tightly pressed together by high temperature. The barrier ring 6 can prevent burrs from appearing after the ceramic ball is formed. Then, the upper mold 4 and the lower mold 1 are separated. Then, the air pump 9 is started to inject air into the exhaust hole in the push plate 8 and the connecting column 10 through the air pipe 12. Then, the gas pushes the push rod 11 upward from the mold groove 3 in the spherical mold, so that the ceramic ball is automatically demolded. Then, the push plate 8 is pushed by the electric telescopic rod 7, which facilitates the upward movement of the connecting column 10 and the spherical mold. Then, the spherical mold can be replaced by rotation.
