Description

Technical Field

[0001] The present invention relates to the field of casting, and in particular to a bimetallic composite ceramic liner casting device and process. Background Art

[0002] Mills are commonly used in grinding equipment in industries such as metallurgy, mining, building materials, and power generation. Ball mill liners are crucial components for protecting the mill and driving the grinding balls to grind and pulverize materials. Ball mill liners operate in harsh environments and are prone to fracture, yielding, and abrasive wear under high-energy, multiple impacts. In practice, multi-metal composite liners are often used. Multi-metal composite ceramic liners typically use a tough carbon steel or alloy steel matrix (to bear the impact load) with a surface composite of ultra-hard, wear-resistant materials such as high-chromium cast iron and ceramics to achieve exceptional wear resistance, impact resistance, and fracture resistance.

[0003] The multi-metal composite ceramic lining is usually prepared in a sand mold during the preparation process, and the metal layers are poured in a double-liquid bimetallic manner or one by one. The multi-metal layer pouring one by one is to first pour one metal, polish it after it is formed, and then put it back into the casting box as a casting mold, pour another metal, and finally polish it into shape.

[0021] Beneficial effects

[0022] 1. The mold of the present invention includes an upper mold and a lower mold. When it is necessary to prepare a cavity in the shape of the first curved plate, the end member can be removed, and then the second curved plate can be pushed downward so that the top surface of the second curved plate is flush with the surface of the middle plate.

When the lower mold frame completes cavity preparation and flips over, the upper mold frame loses its limit and automatically moves downward to the specified position. During the rotation of the lower mold frame, the receiving plate first descends and then rises. It can assist the lower mold frame to complete demolding without affecting the flipping of the lower mold frame. The demolding efficiency is high. At the same time, after the cavity preparation on the upper mold frame is completed, the middle plate is removed and demolded. It can be directly controlled to descend and cooperate with the lower mold frame to realize complete cavity preparation.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a bimetallic composite ceramic liner casting mold, including a mold 100, the mold 100 includes a first curved plate 101 and a second curved plate 102, the first curved plate 101 is fitted with the second curved plate 102, and the length of the first curved plate 101 is smaller than that of the second curved plate 102, one end of the second curved plate 102 is detachably connected to two end parts 103, and the two end parts 103 are symmetrically arranged. In this embodiment, the end part 103 and the second curved plate 102 are detachably connected, and the specific detachable connection method includes snapping, a protrusion is provided on the end part 103, and a notch is provided on the second curved plate 102. When in use, the protrusion on the end part 103 is snapped into the notch on the second curved plate 102 to fix the end part 103 and the second curved plate 102, and the first curved plate 101 and the second curved plate 102 are independent of each other.

[0041] like Figure 13 As shown, the specific preparation process of the bimetallic composite ceramic lining in this embodiment is as follows: first, a ceramic preform matching the shape of the first curved plate 101 is prepared, and then a matching cavity is prepared in the shape of the first curved plate 101, the ceramic preform is placed in the cavity, and the wear-resistant layer metal is poured. After cooling and forming, it is polished to prepare a cavity with a complete shape of the model 100, and the semi-finished product after cooling and polishing is placed in a specified position in the cavity, and a second pouring is performed. After cooling and forming, the bimetallic composite ceramic lining is obtained.

[0042] like Figure 3 The figure shows a bimetallic composite ceramic liner casting device, including a mold mounting mechanism 200, a mold frame 300, a driving mechanism 400, a bottom receiving mechanism 500 and a casting platform 600, wherein the pattern 100 is installed in the mold mounting mechanism 200, and the mold frame 300 is provided with two, which are used for preparing the upper and lower cavities respectively. The mold frame 300 and the mold mounting mechanism 200 are spliced ​​to form a semi-enclosed area for carrying molding sand and preparing the cavity. The bottom receiving mechanism 500 is used to receive the mold frame 300 after the cavity preparation is completed, and the driving mechanism 400 is used to drive the mold frame 300 and the mold mounting mechanism 200 to work.

[0043] During the liner casting process, the casting cavity needs to be prepared in advance. Usually, a frame mold is used, and sand is injected and compacted inward to obtain the upper and lower cavities for casting, and then spliced. In the actual operation process, the casting of the upper and lower cavities is completed independently, and almost entirely relies on manual operation, which is time-consuming and labor-intensive. In this embodiment, a driving mechanism 400 is provided to cooperate with the bottom receiving mechanism 500 and the mold installation mechanism 200, so that the upper cavity mold frame 300 can be synchronously moved downward during the downward rotation and demolding of the lower cavity mold frame 300. After demolding, the upper cavity mold frame 300 moves downward and automatically engages and splices with the lower cavity mold frame 300 to obtain a complete cavity.

[0044] like Figure 4 As shown, the mold frame 300 includes two cross beams 301, and a longitudinal beam 302 is fixed between the two cross beams 301. The two cross beams 301 and the two longitudinal beams 302 form a rectangular structure, which is penetrated from top to bottom, and a first mounting plate 303 is fixed on the back of one of the longitudinal beams 302. The mold frame 300 can be spliced ​​to the upper and lower sides of the mold mounting mechanism 200 respectively, and as the mold mounting mechanism 200 is flipped, demoulding can be achieved in conjunction with the bottom supporting mechanism 500.

[0045] The driving mechanism 400 includes a long base 401, a first support plate 403 is fixed on one end of the long base 401, a second support plate 402 is fixed on the middle part, a first mounting groove 413 is opened on the first support plate 403, a first slide rod 412 is fixed in the first mounting groove 413, a first sliding plate 411 is further provided in the first mounting groove 413, the first sliding plate 411 is slidably connected to the first slide rod 412, a first threaded rod 408 is rotatably provided on the first sliding plate 411, and a first limiting rod 409 is fixed thereon, the first threaded rod 408 is threadedly connected to the first mounting plate 303 on the mold frame 300, and the first slide rod 412 is fixed to the first mounting plate 303. 03 sliding connection, one end of the first threaded rod 408 is also connected to the first motor 410, the first motor 410 is fixedly connected to the first sliding plate 411, the second support plate 402 is fixedly provided with a third mounting plate 404, two second slide rods 405 are fixedly provided in the third mounting plate 404, a sliding member 406 is slidingly provided on the two second slide rods 405, a second mounting plate 407 is fixed on the sliding member 406, the other ends of the first threaded rod 408 and the first limiting rod 409 are fixedly connected to the second mounting plate 407, when in use, the first motor 410 drives the first threaded rod 408 to rotate to realize the movement of the mold frame 300 on the first slide rod 412.

[0046] The mold frame 300 on the first threaded rod 408 is used to prepare the upper cavity. After the lower cavity is prepared, the upper cavity mold frame 300 needs to move downward. After the sand filling is completed, demolding and splicing are required. It needs to remain still during sand filling and demolding, but splicing requires moving downward a certain distance. Therefore, this embodiment achieves the limitation of the upper cavity mold frame 300 by providing a baffle 416.

[0047] like Figure 4 and 5As shown, a second mounting groove 414 is provided at the bottom of the third mounting plate 404, and a first spring 415 is fixedly provided in the second mounting groove 414. A baffle 416 is fixedly connected to the top of the first spring 415, and the baffle 416 is slidably connected to the second slide bar 405. A first latch 417 is slidably provided on the side of the third mounting plate 404. When in use, the first latch 417 is inserted into the third mounting plate 404 to fix the baffle 416 on the third mounting plate 404. When in use, the first latch 417 is pulled out, and the baffle 416 is subjected to downward pressure to compress the first spring 415, and the baffle 416 then slides on the two second slide bars 405.

[0048] like Figure 4 and Figure 6 As shown, the sliding member 406 can also be limited by the second latch on the two second sliding rods 405. The second latch includes a cylindrical rod 419 and a T-shaped end plate 418. The cylindrical rod 419 can be inserted into the sliding member 406 during the lateral movement to limit the sliding member 406. The cylindrical rod 419 is moved lateraly and separated from the sliding member 406, and the sliding member 406 can be slid on the second sliding rod 405. The T-shaped end plate 418 is fixedly connected to the cylindrical rod 419. A second spring 421 is connected between the T-shaped end plate 418 and the third mounting plate 404. There are two sides of the second spring 421 between the T-shaped end plate 418 and the third mounting plate 404. The ends are respectively fixed with a first telescopic rod 420, the end of the T-shaped end plate 418 is also fixed with a first rack 422, and the third mounting plate 404 is located below the first rack 422 and is rotatably provided with a rotating shaft 423, and the rotating shaft 423 is coaxially fixed with a first gear 424 and a first sprocket 425, and the first gear 424 is engaged with the first rack 422 for transmission. The first gear 424 in this embodiment is an incomplete gear. When the first gear 424 rotates, the first gear 424 is engaged with the first rack 422 to realize the movement of the T-shaped end plate 418, and further realizes the insertion of the cylindrical rod 419 into the sliding member 406 or separation from it.

[0049] like Figure 8 As shown, the bottom supporting mechanism 500 includes a U-shaped base 501, on which a plurality of third springs 502 are fixed, a supporting plate 504 is fixed to the top of the third spring 502, a second telescopic rod 503 is fixed between the supporting plate 504 and the U-shaped base 501, and the second telescopic rod 503 is sleeved inside the third spring 502, and third mounting grooves 505 are provided on both sides of the U-shaped base 501, and third sliding rods 506 are provided in the third mounting grooves 505 on both sides, and sixth mounting plates 507 are fixed on both sides of the supporting plate 504, and the sixth mounting plates 507 are respectively slidably connected to the third sliding rods 506, and a vertical plate 508 is also fixed on the sixth mounting plate 507 on one side, and a second rack 509 is fixed on the vertical plate 508.

[0050] When the lower cavity mold frame 300 is prepared and rotated downward for demoulding, it needs to be placed on the supporting plate 504. Therefore, the supporting plate 504 is relatively close to it. In order to avoid obstruction during the flipping process, we provide a third spring 502 to enable the supporting plate 504 to automatically move downward a certain distance during the flipping of the lower cavity mold frame 300 to avoid obstruction. After the flipping is completed, the third spring 502 moves the supporting plate 504 upward to fit with the lower cavity mold frame 300, and demoulding is achieved under the action of gravity.

[0051] The U-shaped base 501 is also rotatably provided with a mold mounting mechanism 200, which includes an intermediate plate 201, on which a mold 100 is mounted, and a fixing mechanism is provided on the mold 100. Figure 9 As shown, fifth mounting plates 202 are fixedly provided on both sides of the middle plate 201, and fourth mounting plates 203 are rotatably provided on both sides of the U-shaped base 501. The fourth mounting plates 203 on both sides are detachably connected to the two fifth mounting plates 202, wherein the detachable connection is a snap connection, and a third latch 204 is further provided between the fourth mounting plate 203 and the fifth mounting plate 202. The third latch 204 is a U-shaped structure, and the two U-shaped pins are respectively inserted into the fourth mounting plate 203 and the fifth mounting plate 202 to limit the fourth mounting plate 203 and the fifth mounting plate 202. The U-shaped base 501 is located on the second rack 50 A second gear 205 is also rotatably provided on the same side. The second gear 205 is coaxial with and fixedly connected to the fourth mounting plate 203 on the same side. When the intermediate plate 201 rotates, the second gear 205 rotates, meshing with the second rack 509 for transmission, further realizing the up and down movement of the second rack 509. The second rack 509 is fixedly connected to the supporting plate 504, thereby realizing the up and down movement of the supporting plate 504. In this embodiment, the second gear 205 is an incomplete gear. When the second gear 205 does not mesh with the second rack 509 during rotation, the second rack 509 will return to its initial position under the action of the third spring 502.

[0052] In this embodiment, in order to ensure that the mold frames 300 of the upper and lower cavities fit more closely, we connect the two by providing a chain 426, so that the mold frame 300 of the upper cavity can be moved synchronously during the flipping process of the mold frame 300 of the lower cavity.

[0053] like Figure 4 and Figure 7 As shown, a second sprocket 211 is coaxially and fixedly provided on the fourth mounting plate 203 on the other side, and the second sprocket 211 is connected to the first sprocket 425 via a chain 426. A second motor 210 is also fixedly provided on the U-shaped base 501 via a motor mounting plate 209, and the output end of the second motor 210 is connected to the second sprocket 211.

[0054] The rotation of the middle plate 201 can be achieved through the second motor 210, and the rotation of the first sprocket 425 can be achieved through the chain 426. The first sprocket 425 can realize the rotation of the first gear 424 through the rotating shaft 423. The first gear 424 is engaged with the first rack 422 for transmission, so that the lateral movement of the first rack 422 can be achieved and the lateral movement of the cylindrical rod 419 can be further achieved. The cylindrical rod 419 is pulled out from the sliding member 406, and the sliding member 406 loses its limit and starts to move downward under the action of gravity.

[0055] like Figure 3 As shown, first, a mold frame 300 is taken for the preparation of the lower cavity, and the mold frame 300 is spliced ​​on the middle plate 201 of the mold mounting mechanism 200. Then, the shape of the pattern 100 is adjusted and sand is filled. After the sand filling is completed, it is compacted and leveled. Then, the middle plate 201 is driven to rotate by the second motor 210, and the middle plate 201 drives the compacted mold frame 300 to rotate downward until it is flipped 180°. At this time, the lower cavity mold frame 300 is flipped to a horizontal position above the carrier plate 504, as shown in FIG. Figure 8 As shown, when the middle plate 201 is flipped counterclockwise, the second gear 205 rotates counterclockwise synchronously and meshes with the second rack 509, and the second rack 509 drives the supporting plate 504 to move downward synchronously to prevent the middle plate 201 and the upper mold frame 300 from being blocked by the supporting plate 504 during the flipping process. That is, when the mold frame 300 starts to flip, the supporting plate 504 will move downward a certain distance. When the mold frame 300 is about to complete the flipping, the second rack 509 and the second gear 205 are no longer meshed. Under the action of the third spring 502, the supporting plate 504 moves upward and gradually fits with the bottom of the flipped mold frame 300 and plays a certain supporting role. At this time, the middle plate 201 is knocked again. Under the action of the gravity of the mold frame 300 and the sand and gravel inside it, the mold frame 300 is gradually separated from the middle plate 201 to complete the demoulding. The mold frame 300 after demoulding is located on the supporting plate 504 and compresses the supporting plate 504 downward a certain distance.

[0056] like Figure 6As shown, at the same time, when the middle plate 201 rotates, the second sprocket 211 and the first sprocket 425 rotate synchronously through the chain 426, and the first sprocket 425 realizes the rotation of the first gear 424 through the rotating shaft 423. The first gear 424 is engaged with the first rack 422 for transmission, and the lateral movement of the first rack 422 is realized, and the lateral movement of the cylindrical rod 419 is further realized. The cylindrical rod 419 is pulled out from the sliding member 406, and the sliding member 406 loses its limit. Under the action of gravity, the mold frame 300 for preparing the upper cavity thereon starts to move slowly downward. There is a certain friction resistance on the second sliding bar 405 to prevent the mold frame 300 from falling vertically, and ensure that the mold frame 300 of the upper cavity does not drop to the lowest point before the middle plate 201 is flipped over. Figure 5 As shown, the lowest point is the baffle 416. When the sliding member 406 reaches the baffle 416, it will be blocked and the sliding member 406 stops moving. After the middle plate 201 is flipped, the internal mold 100 is also flipped so that the upper mold faces upward. The mold frame 300 of the upper cavity is also filled with sand, leveled and compacted. After the operation is completed, the third latch 204 is removed, the fourth mounting plate 203 and the fifth mounting plate 202 on both sides are separated, and the middle plate 201 is separated from the mold frame 300 of the upper cavity. At this point, the upper cavity preparation is completed. After the middle plate 201 is taken out, the first latch 417 is pulled out, and the mold frame 300 of the upper cavity will compress the first spring 415. The upper cavity mold frame 300 moves downward and gradually splices and engages with the lower cavity mold frame 300 to form a complete cavity. Finally, the first threaded rod 408 drives the upper cavity mold frame 300 to drive the lower cavity mold frame 300 to move as a whole toward the casting platform 600 for casting.

[0057] like Figure 10 and Figure 11 As shown, the mold 100 is respectively an upper mold and a lower mold, and the middle plate 201 is located in the middle position of the mold 100. The mold 100 passes through the middle plate 201, and its upper mold and lower mold are respectively located at the upper and lower ends of the middle plate 201. The first curved plate 101 of the mold 100 is fixedly connected to the middle plate 201, and the second curved plate 102 is slidably connected to the middle plate 201. When it is necessary to prepare a cavity in the shape of the first curved plate 101, the end component 103 can be removed, and then the second curved plate 102 can be pushed downward so that the top surface of the second curved plate 102 is flush with the plate surface of the middle plate 201, and the cavity in the shape of the first curved plate 101 can be prepared.

[0058] like Figure 10As shown, the mold 100 is provided with a fixing mechanism, specifically including a U-shaped clamp 206, and the U-shaped clamp 206 is threadedly matched with a second threaded rod 208, and one end of the second threaded rod 208 is rotatably provided with a clamping plate 207, and the U-shaped clamp 206 is placed between the first curved plate 101 and the second curved plate 102, and the second threaded rod 208 is rotated to make the clamping plate 207 fit with the second curved plate 102 and clamp it, so as to fix the first curved plate 101 and the second curved plate 102, and avoid the second curved plate 102 from relative displacement with respect to the first curved plate 101, which affects the preparation of the mold.

[0059] like Figure 1-12 As shown, a casting process for a bimetallic composite ceramic liner casting device includes the following steps:

[0060] Step 1: First, take a mold frame 300 for preparing the lower cavity, splice it on the middle plate 201 of the mold mounting mechanism 200, push the second curved plate 102 downward so that the top surface of the second curved plate 102 is flush with the surface of the middle plate 201, and fix it with a fixing mechanism. After filling with sand, a cavity in the shape of the first curved plate 101 is prepared;

[0061] Step 2: After preparation is completed, the middle plate 201 is turned over. After demolding, the lower cavity mold frame 300 is located on the carrying plate 504. At the same time, the upper cavity mold frame 300 begins to descend and reaches the designated position. After filling with sand and compacting, the middle plate 201 is removed for demolding. Then, the ceramic preform is placed in the prepared cavity. The first latch 417 is pulled out, and the upper cavity mold frame 300 moves downward and gradually splices and engages with the lower cavity mold frame 300 to form a complete cavity. Finally, the first threaded rod 408 drives the upper cavity mold frame 300 to drive the lower cavity mold frame 300 to move as a whole toward the casting platform 600 to perform the first layer of metal casting.

[0062] Step 3: After the first layer of metal casting is completed, it is cooled and polished, and the shape of the pattern 100 is adjusted to prepare a complete pattern 100 shape cavity. The polished first layer of metal is then placed in the designated position, and the second layer of metal is cast after sandblasting.
