[0002] A liner is a plate or structural component used for support and protection, and is applied in multiple fields. It usually needs to have the characteristics of load-bearing and wear resistance, and for special fields, the liner has functions such as insulation or isolation; the liners made of traditional materials all have certain shortcomings more or less. At this time, alloy materials are needed to meet various requirements, and other materials can also be added to enhance the characteristics. The wear-resistant alloy ceramic liner is a common alloy liner. The wear-resistant alloy ceramic liner is a material widely used in fields that require anti-wear, especially in industries such as mining, metallurgy, and chemical industry. Its main characteristics are excellent wear resistance, corrosion resistance, impact resistance, etc. Its application can effectively extend the service life of equipment and reduce maintenance costs. During the processing, the mixed powder needs to be put into a mold and pressed into shape under high pressure.

[0043] During use, place the mold 307 on the incoming conveyor belt 306. The lower bevel gear 204 drives the side bevel gear 304 to rotate, thereby driving the incoming conveyor belt 306 to transport the mold 307 to the turntable 121. At the same time, the driving cylinder 313 drives the driven cylinder 312 to rotate through the bending transmission rod 314, thereby driving the inner output wheel 310 to rotate, and then driving the output conveyor belt 315 to move. All the raw materials are put into the completed mold 307 through the push block 316 and transported from the turntable 121 to the lower part of the die-casting block 319. At this time, the output conveyor belt 315 stops moving. The die-casting electric cylinder 318 extends to drive the die-casting block 319 to descend. The die-casting block 319 presses the lid 322 located on the blocking rod 320 into the mold 307. The blocking rod 320 slides outwards, and the blocking spring 321 is compressed. When the lid 322 passes through, the blocking rod 320 resets under the action of the blocking spring 321. When the lid 322 contacts the clamping plate 308, the lid 322 pushes the clamping plate 308 to slide outwards, and the clamping plate spring 309 is compressed. After the lid 322 enters the mold 307, the raw material powder in the mold 307 is die-cast by the lid 322. After the die-casting electric cylinder 318 contracts, the next lid 322 in the lid box 317 slides onto the blocking rod 320. The blocking rod 320 prevents the lid 322 from falling directly and stays below the die-casting electric cylinder 318.

[0044] The working principle of the casting device for a wear-resistant alloy ceramic lining plate disclosed by the present invention is as follows: The motor 103 drives the motor wheel 104 to rotate, drives the upper wheel 107 and the lower wheel 108 to rotate through the output belt 105, and drives the intermediate wheel 112, the upper docking gear 111 and the lower docking gear 113 to rotate through the lower transmission belt 110. When the electric cylinder 114 retracts, the lower docking gear 113 meshes with the central gear 120, and the lower docking gear 113 drives the central gear 120 and the rotating column 119 to rotate, driving the lifting rod 123 to lift along the lifting track platform 122. Each time the lower docking gear 113 drives the central gear 120 and the rotating column 119 to rotate by ninety degrees. When the electric cylinder 114 extends, the upper docking gear 111 meshes with the intermediate gear 116, and the upper docking gear 111 drives the intermediate gear 116 to rotate, driving the internal gear 203 and the lower bevel gear 204 to rotate, driving the external gear 202 and the internal threaded column 201 to rotate. During use, the mold 307 is placed on the incoming conveyor belt 306. The lower bevel gear 204 drives the side bevel gear 304 to rotate, thereby driving the incoming conveyor belt 306 to transport the mold 307 to the rotating frame 121. Through the cooperation of the internal thread of the internal threaded column 201 and the convex ball 209, the internal column 206, the descending frame 205 and the switch plate 208 are lifted once, and the raw material powder in the raw material box 207 slides out into the mold 307 in front of the raw material box 207. When the mold 307 is beside the two raw material boxes 207, the lifting rod 123 is located at the lower layer of the lifting track platform 122, and the stirring fan blade 126 extends into the mold 307. When the mold 307 is beside the mold inlet frame 301 and the mold outlet frame 302, the lifting rod 123 is located at the upper layer of the lifting track platform 122, and the stirring fan blade 126 is above the mold 307, facilitating the entry and exit of the mold 307. When the lifting rod 123 is located at the lower layer of the lifting track platform 122, with the rotation of the rotating column 119 relative to the fixed column 117, under the action of the fixed gear 118, the top gear 125, the stirring shaft 124 and the stirring fan blade 126 rotate, and the raw material powder is mixed by the stirring fan blade 126.Meanwhile, the driving cylinder 313 drives the driven cylinder 312 to rotate through the bent transmission rod 314, thereby driving the inner output wheel 310 to rotate, and then driving the output transmission belt 315 to move. All the raw materials are put into the completed mold 307 through the push block 316 and conveyed from the turntable 121 to the lower part of the die-casting block 319. At this time, the output transmission belt 315 stops moving. The die-casting electric cylinder 318 extends to drive the die-casting block 319 to descend. The die-casting block 319 presses the lid 322 located on the blocking rod 320 into the mold 307. The blocking rod 320 slides outwards, and the blocking spring 321 is compressed. When the lid 322 passes through, the blocking rod 320 resets under the action of the blocking spring 321. When the lid 322 contacts the clamping plate block 308, the lid 322 pushes the clamping plate block 308 to slide outwards, and the clamping plate spring 309 is compressed. After the lid 322 enters the mold 307, the raw material powder in the mold 307 is die-cast by the lid 322. After the die-casting electric cylinder 318 contracts, the next lid 322 in the lid box 317 slides onto the blocking rod 320. The blocking rod 320 prevents the lid 322 from falling directly and stays below the die-casting electric cylinder 318.
