Description

Technical Field

[0001] The present invention relates to the technical field of refractory material pouring, and particularly relates to an automatic mold closing machine for a pouring mold. Background Art

[0002] A new type of refractory material is formed by pouring in a mold. The mold consists of two parts. One part is a multi-cavity mold made of PVC material, and the other part is a mold bottom plate. When producing this refractory material, the PVC mold is placed on the mold bottom plate. The raw materials of the refractory material are poured into the mold cavities of the PVC mold. After the raw materials solidify, the PVC mold needs to be separated from the mold bottom plate. After the PVC mold is removed, there remains a refractory material product on the mold bottom plate. After drying, the refractory material product is sent into a firing kiln. After the mold bottom plate returns to its position, the PVC mold needs to be accurately placed at the center of the mold bottom plate. However, currently, it is basically carried out manually, with a large labor intensity and low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic mold closing machine for a pouring mold to solve one or more technical problems existing in the prior art, and at least provide a beneficial alternative or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] The present invention provides an automatic mold closing machine for a pouring mold, which includes:

[0006] A conveying mechanism;

[0007] A centering mechanism, which includes a first centering member and a second centering member. There are two first centering members, which are respectively located on the left and right sides of the conveying mechanism. The two first centering members can approach or move away from each other. The first centering member is provided with a first positioning member for left-right centering of the mold bottom plate and a second positioning member for left-right centering of the mold. The second positioning member is located above the first positioning member. The second centering member is arranged on the first centering member. There are two second centering members, which are respectively located on the front and rear sides of the first centering member. The two second centering members can approach or move away from each other. The second centering member is provided with a third positioning member for front-back centering of the mold bottom plate and a fourth positioning member for front-back centering of the mold. The fourth positioning member is located above the third positioning member;

[0008] A clamping manipulator, which is arranged on one side of the conveying mechanism and is used for clamping the mold to the conveying mechanism.

[0009] The present invention has at least the following beneficial effects: The conveying mechanism can be connected to the conveying line of the firing kiln, and is used for conveying the mold and the mold bottom plate, so as to promote the recycling of the mold bottom plate. The clamping manipulator is arranged on one side of the conveying mechanism, and can clamp the mold and place it on the mold bottom plate on the conveying mechanism, so as to close the mold and the mold bottom plate, so that the raw material of the refractory material can be poured into the mold cavity.

[0010] Moreover, the centering mechanism includes a first centering member and a second centering member. Two first centering members are arranged on the left and right sides of the conveying mechanism and can approach each other. The first positioning member is used to push the mold bottom plate to move in the left-right direction, and the second positioning member is used to push the mold to move in the left-right direction, so as to complete the centering work of the mold and the mold bottom plate in the left-right direction; Two second centering members are arranged on the first centering member and can move along the left-right direction with the first centering member. The second centering members are arranged on the front side and the rear side of the first centering member, and the two second centering members can approach each other. The third positioning member is used to push the mold bottom plate to move in the front-rear direction, and the fourth positioning member is used to push the mold to move in the front-rear direction, so as to complete the centering work of the mold and the mold bottom plate in the front-rear direction. The setting of the centering mechanism ultimately ensures that the mold can move to the center position of the mold bottom plate, and can efficiently complete the automatic mold closing work.

[0011] As a further improvement of the above technical solution, the first centering member includes:

[0012] A support frame;

[0013] A first sliding seat, which is connected to the support frame and can move relative to the support frame in the left-right direction. The first sliding seat is provided with the first positioning member and the second positioning member;

[0014] A first driving device, which is connected to the first sliding seat to drive the first sliding seat to move in the left-right direction.

[0015] The first sliding seat is slidably connected to the support frame, the first driving device is connected to the first sliding seat, and the first driving device can drive the first sliding seat to move left or right. The first positioning member and the second positioning member are both arranged on the first sliding seat and can move together with the first sliding seat, so as to perform the left-right centering work on the mold and the mold bottom plate.

[0016] As a further improvement of the above technical solution, the first driving device is a first telescopic cylinder. One end of the first telescopic cylinder is connected to one of the first sliding seats, and the other end of the first telescopic cylinder is connected to the other first sliding seat; The first sliding seat is provided with a first limit block, the first limit block is located inside the first sliding seat, and the support frame is provided with a second limit block, and the second limit block is located outside the first sliding seat.

[0017] The first driving device adopts a first telescopic cylinder, which is fast and stable in operation. Moreover, the two ends of the first telescopic cylinder are respectively connected to two first sliding seats, which can drive the two first sliding seats to approach or move away from each other, reducing the equipment manufacturing cost and energy consumption.

[0018] In addition, the first sliding seat is provided with a first limit block, which is located inside the first sliding seat. When the first telescopic cylinder drives the two first sliding seats to approach each other, the first limit block abuts against the conveying mechanism, prompting the two first sliding seats to be symmetric about the conveying mechanism left and right. Thus, while the first positioning member and the second positioning member perform left-right centering of the mold and the mold bottom plate, it is ensured that the mold and the mold bottom plate are located at the center position of the conveying mechanism, ensuring the unified arrangement of multiple molds and multiple mold bottom plates located on the conveying mechanism.

[0019] The support frame is provided with a second limit block, which is located outside the first sliding seat. When the first telescopic cylinder drives the two first sliding seats to move away from each other, the second limit block abuts against the first sliding seat to ensure that the first sliding seat moves in place to the outside, thereby preventing the first positioning member and the second positioning member on the first sliding seat from obstructing the mold and the mold bottom plate.

[0020] As a further improvement of the above technical solution, the second centering component includes:

[0021] A second sliding seat, which is connected to the first sliding seat and can move relative to the first sliding seat in the front-rear direction; the second sliding seat is provided with the third positioning member and the fourth positioning member;

[0022] A second driving device, which is connected to the second sliding seat to drive the second sliding seat to move in the front-rear direction.

[0023] The second sliding seat is connected to the first sliding seat and can move left or right with the first sliding seat, which can prevent the second centering component from obstructing the mold bottom plate conveyed. Moreover, there is no need to set up an additional driving device to drive the second centering component to move in the left-right direction, reducing the manufacturing cost and energy consumption. The second driving device is connected to the second sliding seat and can drive the second sliding seat to move forward or backward. Both the third positioning member and the fourth positioning member are arranged on the second sliding seat and can move together with the second sliding seat, thereby performing front-back centering work on the mold and the mold bottom plate.

[0024] As a further improvement of the above technical solution, the second driving device is a second telescopic cylinder. One end of the second telescopic cylinder is connected to one of the second sliding seats, and the other end of the second telescopic cylinder is connected to the other second sliding seat. The second driving device adopts a second telescopic cylinder, which has rapid and stable operation. Moreover, the two ends of the second telescopic cylinder are respectively connected to two second sliding seats correspondingly, which can drive the two second sliding seats to approach or move away from each other, reducing the manufacturing cost of the equipment and lowering the energy consumption.

[0025] As a further improvement of the above technical solution, the first positioning member and the second positioning member are positioning wheels, and the axis of the positioning wheel extends vertically; the third positioning member and the fourth positioning member are positioning blocks. Since the moving directions of the first positioning member and the second positioning member are perpendicular to the conveying direction of the conveying mechanism, the first positioning member and the second positioning member adopt positioning wheels, and the axis of the positioning wheel extends vertically. When the positioning wheels are respectively abutted against the mold and the mold bottom plate, the positioning wheels will rotate, thereby reducing the friction force between the positioning wheels and the mold and the mold bottom plate respectively. The third positioning member and the fourth positioning member adopt positioning blocks, which can increase the contact area between the positioning blocks and the mold and the mold bottom plate respectively, thereby preventing the mold and the mold bottom plate from being damaged due to excessive pressure applied by the positioning blocks.

[0026] As a further improvement of the above technical solution, the clamping manipulator includes:

[0027] A clamping mechanism, which includes a fixed frame, clamping arms and a third driving device. There are two clamping arms, and both clamping arms are connected to the fixed frame. The clamping arms are provided with clamping blocks, and the third driving device is connected to the clamping arms to drive the two clamping arms to approach or move away from each other;

[0028] A fourth driving device, which is connected to the fixed frame to drive the fixed frame to move in the vertical direction;

[0029] A fifth driving device, which is connected to the fourth driving device to drive the fourth driving device to move in the left-right direction.

[0030] The clamping mechanism includes a fixed frame, clamping arms and a third driving device. There are two clamping arms, both of which are connected to the fixed frame. The third driving device is connected to the clamping arms and can drive the two clamping arms to approach each other. The mold is stably clamped by the clamping blocks provided on the clamping arms. Moreover, the fourth driving device is connected to the fixed frame, and the fifth driving device is connected to the fourth driving device. The fourth driving device can drive the clamping mechanism to move up or down, and the fifth driving device drives the fourth driving device and the clamping mechanism to move left or right. Finally, the clamping mechanism clamps the mold and transports it to the top surface of the mold bottom plate on the conveying mechanism.

[0031] As a further improvement of the above technical solution, the third driving device is a third telescopic cylinder, one end of the third telescopic cylinder is connected to one of the clamping arms, and the other end of the third telescopic cylinder is connected to the other clamping arm; the clamping arm is provided with a braking cylinder, and the braking cylinder is provided with a movable end that can abut against the fixing frame.

[0032] The third driving device adopts a third telescopic cylinder, which has rapid and stable operation. The two ends of the third telescopic cylinder are respectively connected to the two clamping arms, and can drive the two clamping arms to approach or move away from each other. Moreover, the clamping arm is provided with a braking cylinder, and the braking cylinder is provided with a movable end that can abut against the fixing frame. The braking cylinder abuts against the fixing frame through its movable end to drive the two clamping arms to be stable relative to the fixing frame, thereby avoiding the clamping arms from moving left and right relative to the fixing frame during the operation of the fifth driving device, resulting in severe shaking of the mold, and greatly improving the stability of the clamping mechanism when clamping and transporting the mold.

[0033] As a further improvement of the above technical solution, the fifth driving device includes:

[0034] A frame, which is provided with a transmission member, and both ends of the transmission member extend in the left-right direction;

[0035] A translation frame, which is connected to the frame and can move in the left-right direction;

[0036] A first motor, which is arranged on the translation frame, and the output shaft of the first motor is provided with a transmission wheel, and the transmission member is wound around the transmission wheel.

[0037] The translation frame is connected to the frame and can move relative to the frame. The first motor is arranged on the translation frame, and the output shaft of the first motor is provided with a transmission wheel. Moreover, a transmission member is arranged on the frame, and both ends of the transmission member extend in the left and right directions, and the transmission member is wound around the transmission wheel. When the first motor drives the transmission wheel to rotate, the transmission wheel can move linearly relative to the transmission member, so as to realize that the translation frame can frequently move left or right relative to the frame.

[0038] As a further improvement of the above technical solution, a positioning guide wheel is provided at the top of the fixing frame, and a positioning groove is provided at the bottom of the translation frame, and the positioning guide wheel can be adaptively connected to the positioning groove; the fourth driving device includes:

[0039] A second motor, which is arranged on the translation frame, and the output shaft of the second motor is provided with a first driven wheel;

[0040] A second driven wheel, which is arranged on the translation frame and can rotate around its horizontal axis;

[0041] A first chain, which is wound between the first driven wheel and the second driven wheel;

[0042] A third driven wheel, which is arranged on the translation frame and can rotate around its horizontal axis;

[0043] A second chain, one end of which is connected to the first chain, and the other end of the second chain is connected to one end of the fixed frame. The second chain is wound around the third driven wheel;

[0044] A fourth driven wheel, which is arranged on the translation frame and can rotate around its horizontal axis;

[0045] A fifth driven wheel, which is arranged on the translation frame and can rotate around its horizontal axis;

[0046] A third chain, one end of which is connected to the first chain, and the other end of the third chain is connected to the other end of the fixed frame. The third chain is wound around the fourth driven wheel and the fifth driven wheel.

[0047] A second motor and a second driven wheel are arranged on the translation frame. A first driven wheel is arranged on the output shaft of the second motor. The first chain is wound between the first driven wheel and the second driven wheel; a second chain and a third chain are arranged. One end of the second chain is connected to the first chain, and the other end is connected to one end of the fixed frame. One end of the third chain is connected to the first chain, and the other end is connected to the other end of the fixed frame. And a third driven wheel, a fourth driven wheel and a fifth driven wheel are arranged on the translation frame. The second chain is wound around the third driven wheel, and the third chain is wound around the fourth driven wheel and the fifth driven wheel. When the second motor operates, the first chain can operate and drive the second chain and the third chain to move, so that the second chain and the third chain move in the same direction, thereby realizing that the second chain and the third chain can pull up the fixed frame.

[0048] Moreover, a positioning guide wheel is arranged at the top of the fixed frame, and a positioning groove is arranged at the bottom of the translation frame. After the second chain and the third chain jointly apply force to the fixed frame and drive the fixed frame to move up in place, the positioning guide wheel is adaptively connected to the positioning groove, so that the fixed frame is relatively stable and immovable relative to the translation frame, thereby avoiding the fixed frame from shaking left and right relative to the translation frame during the process of the translation frame moving in the left and right directions, and further preventing the fixed frame from causing harm to surrounding equipment or personnel.

[0070] Reference Figures 1 to 10 , several embodiments of the automatic mold closing machine for the casting mold of the present invention are given below.

[0071] As Figures 1 to 10 shown, an embodiment of the present invention provides an automatic mold closing machine for a casting mold, which includes: a conveying mechanism 600, a centering mechanism 400, and a clamping manipulator.

[0072] Among them, the conveying mechanism 600 can be connected to the dried return plate line, can send the mold 510 (the mold 510 is sent by the mold conveyor 900) and the mold bottom plate 520 into the casting workshop for re-casting after mold closing, and can send the mold bottom plate 520 coming out of the drying kiln to the centering mechanism 400 to complete the mold closing work of the mold 510 and the mold bottom plate 520. The conveying mechanism 600 can be a chain conveyor, a roller conveyor or others. In this embodiment, the mold 510 is a PVC mold. After mold closing, the mold 510 is located at the center position on the upper surface of the mold bottom plate 520. The mold 510 is square, and the mold bottom plate 520 is a square plate. The mold 510 can be, but is not limited to, a casting mold made of refractory materials.

[0073] The centering mechanism 400 includes a first centering member and a second centering member.

[0074] There are two first centering members, which are respectively located on the left and right sides of the conveying mechanism 600. The two first centering members can move closer to or away from each other. The first centering member is provided with a first positioning member 413 for left-right centering of the mold bottom plate 520 and a second positioning member 414 for left-right centering of the mold 510. The second positioning member 414 is located above the first positioning member 413. One or more first positioning members 413 and second positioning members 414 can be arranged along the front-back direction.

[0075] As Figure 2 , Figure 7 , Figure 8 and Figure 9 shown, specifically, the first centering member includes a support frame 430, a first sliding seat 411, and a first driving device.

[0076] The support frame 430 can be formed by connecting multiple profiles. In this embodiment, the support frame 430 is fixed to the conveying mechanism 600.

[0077] The first sliding seat 411 is made of metal material. There are two first sliding seats 411, which are respectively located on the left and right sides of the conveying mechanism 600. A second slider 418 is provided at the bottom of the first sliding seat 411. Correspondingly, a second slide rail 431 is provided on the support frame 430. The first sliding seat 411 is connected to the support frame 430 and can move relative to the support frame 430 in the left - right direction through the sliding connection between the second slider 418 and the second slide rail 431. Of course, it is not excluded to adopt the way of guide rail and guide wheel to realize the movement of the first sliding seat 411 relative to the support frame 430.

[0078] The first sliding seat 411 is provided with a first positioning member 413 and a second positioning member 414. Since the bottom surface of the mold 510 is smaller than the top surface of the mold bottom plate 520, the first positioning member 413 is located outside the second positioning member 414 (that is, the side of the second positioning member 414 away from the conveying mechanism 600).

[0079] In this embodiment, the first positioning member 413 and the second positioning member 414 are positioning wheels, and the axis of the positioning wheel extends vertically. Since the moving direction of the first positioning member 413 and the second positioning member 414 is perpendicular to the conveying direction of the conveying mechanism 600, when the first positioning member 413 contacts the side surface of the mold bottom plate 520 and the second positioning member 414 contacts the side surface of the mold 510, the positioning wheel can rotate around its axis, reducing the frictional force between the positioning wheel and the mold 510 and the mold bottom plate 520 respectively. Of course, the first positioning member 413 and the second positioning member 414 can also be square - shaped or cylindrical positioning blocks.

[0080] The first driving device is connected to the first sliding seat 411 to drive the first sliding seat 411 to move in the left - right direction.

[0081] More specifically, the first driving device is a first telescopic cylinder 412. One end of the first telescopic cylinder 412 is connected to one of the first sliding seats 411 through bolts, and the other end of the first telescopic cylinder 412 is connected to the other first sliding seat 411. When the telescopic rod of the first telescopic cylinder 412 shortens, the two first sliding seats 411 approach each other, so as to apply forces to the mold bottom plate 520 and the mold 510 respectively through the first positioning member 413 and the second positioning member 414, completing the left - right centering of the mold bottom plate 520 and the mold 510, that is, the mold 510 is located at the center position of the mold bottom plate 520 in the left - right direction. The first telescopic cylinder 412 drives the two first sliding seats 411 to approach or move away from each other simultaneously, which can reduce the manufacturing cost of the equipment and lower the energy consumption.

[0082] The first sliding seat 411 is provided with a first limiting block 415. The first limiting block 415 is located inside the first sliding seat 411 (i.e., the side of the first sliding seat 411 close to the conveying mechanism 600). When the first telescopic cylinder 412 drives the two first sliding seats 411 to approach each other, the first limiting block 415 abuts against the conveying mechanism 600 (such as the outer side of the conveying mechanism 600), prompting the two first sliding seats 411 to be symmetric about the conveying mechanism 600. Thus, while the first positioning member 413 and the second positioning member 414 perform left - right centering of the mold 510 and the mold bottom plate 520, it can ensure that the mold 510 and the mold bottom plate 520 are located at the central position of the conveying mechanism 600, ultimately ensuring that multiple molds 510 and multiple mold bottom plates 520 located on the conveying mechanism 600 can be uniformly arranged and fed into the firing kiln.

[0083] Moreover, the support frame 430 is provided with a second limiting block 416. The second limiting block 416 is located outside the first sliding seat 411. When the first telescopic cylinder 412 drives the two first sliding seats 411 to move away from each other, the second limiting block 416 abuts against the outer side of the first sliding seat 411 to ensure that the first sliding seat 411 moves to the outer side in place, thereby preventing the first positioning member 413 and the second positioning member 414 on the first sliding seat 411 from respectively hindering the mold 510 and the mold bottom plate 520.

[0084] The first limiting block 415 and the second limiting block 416 can be metal parts, rubber parts or others.

[0085] Of course, the first driving device can be a telescopic cylinder, a lead screw driving mechanism or a linear module, respectively driving each first sliding seat 411 to move linearly.

[0086] The second centering member is arranged on the first centering member. There are two second centering members, which are respectively located on the front side and the rear side of the first centering member. The two second centering members can approach or move away from each other. The second centering member is provided with a third positioning member 422 for front - rear centering of the mold bottom plate 520 and a fourth positioning member 421 for front - rear centering of the mold 510. The fourth positioning member 421 is located above the third positioning member 422. One or more third positioning members 422 and fourth positioning members 421 can be arranged along the left - right direction.

[0087] Such as Figure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown in

[0088] The second sliding seat 423 is made of a metal material. A third slider 424 is provided at the bottom of the second sliding seat 423. Correspondingly, a third slide rail 417 is provided on the first sliding seat 411. The second sliding seat 423 is connected to the first sliding seat 411 and can move relative to the first sliding seat 411 in the front-back direction through the sliding connection between the third slider 424 and the third slide rail 417. Of course, it is not excluded to adopt the way of guide rails and guide wheels to realize the movement of the second sliding seat 423 relative to the first sliding seat 411.

[0089] The second sliding seat 423 is provided with a third positioning member 422 and a fourth positioning member 421. Since the bottom surface of the mold 510 is smaller than the top surface of the mold bottom plate 520, the third positioning member 422 is located outside the fourth positioning member 421 (that is, the side where the fourth positioning member 421 is away from the mold 510). In this embodiment, the third positioning member 422 and the fourth positioning member 421 are positioning blocks. The positioning blocks can be square or cylindrical. Of course, the third positioning member 422 and the fourth positioning member 421 can also be positioning wheels with axes extending vertically.

[0090] The second driving device is connected to the second sliding seat 423 to drive the second sliding seat 423 to move in the front-back direction.

[0091] More specifically, the second driving device is a second telescopic cylinder 425. One end of the second telescopic cylinder 425 is connected to one of the second sliding seats 423 by bolts, and the other end of the second telescopic cylinder 425 is connected to the other second sliding seat 423. When the telescopic rod of the second telescopic cylinder 425 shortens, the two second sliding seats 423 approach each other, so as to apply forces to the mold bottom plate 520 and the mold 510 respectively through the third positioning member 422 and the fourth positioning member 421, and complete the front-back centering work of the mold bottom plate 520 and the mold 510, that is, the mold 510 is located at the central position of the mold bottom plate 520 in the front-back direction. The second telescopic cylinder 425 drives the two second sliding seats 423 to approach or move away from each other simultaneously, which can reduce the manufacturing cost of the equipment and lower the energy consumption.

[0092] Of course, the second driving device can be a telescopic cylinder, a screw driving mechanism or a linear module, which respectively drive each second sliding seat 423 to move linearly.

[0093] In this embodiment, each first sliding seat 411 is provided with two second centering components, and the two second centering components are respectively located on the front side and the rear side of the first sliding seat 411. Of course, it is not excluded to only set two second centering components on one of the first sliding seats 411.

[0094] In some embodiments, such as Figure 8As shown, the first sliding seat 411 is provided with a third limiting block 426 and a fourth limiting block 427. The third limiting block 426 and the fourth limiting block 427 are installed on the first sliding seat 411 by bolts. The third limiting block 426 is located inside the second sliding seat 423, and the fourth limiting block 427 is located outside the second sliding seat 423. When the second sliding seat 423 moves outward in place, the fourth limiting block 427 will abut against the third slider 424 of the second sliding seat 423; when the second sliding seat 423 moves inward in place, the third limiting block 426 will abut against the third slider 424 of the second sliding seat 423.

[0095] The setting of the third limiting block 426 and the fourth limiting block 427 plays a good limiting role, which can limit the position of the second sliding seat 423 on the third slide rail 417 and prevent the second sliding seat 423 from disengaging from the third slide rail 417. The third limiting block 426 and the fourth limiting block 427 can be metal parts, rubber parts or others.

[0096] As Figures 1 to 6 shown, the clamping manipulator is arranged on one side of the conveying mechanism 600 and is used to clamp the mold 510 to the conveying mechanism 600. Since the conveying direction of the conveying mechanism 600 is along the front-back direction, the clamping manipulator is arranged on the left or right side of the conveying mechanism 600.

[0097] Specifically, the clamping manipulator includes a clamping mechanism 300, a fourth driving device 200 and a fifth driving device 100.

[0098] The clamping mechanism 300 includes a fixing frame 310, clamping arms 340 and a third driving device.

[0099] The fixing frame 310 can be connected by multiple profiles.

[0100] The clamping arms 340 are made of metal. There are two clamping arms 340, and both clamping arms 340 are connected to the fixing frame 310. Specifically, the clamping arms 340 are provided with first sliders 341. Correspondingly, the fixing frame 310 is provided with first slide rails 311. The first slide rails 311 can be arranged at the top or bottom of the fixing frame 310. In this embodiment, the two ends of the first slide rails 311 extend along the front-back direction. Of course, the two ends of the first slide rails 311 can also extend along the left-right direction. In addition, the way of using guide rails and guide wheels can also be adopted to realize the movable connection between the clamping arms 340 and the fixing frame 310.

[0101] Moreover, the clamping arms 340 are provided with clamping blocks 350. The clamping blocks 350 are located inside the clamping arms 340, and the clamping blocks 350 can be rubber blocks.

[0102] The third driving device is connected to the clamping arms 340 to drive the two clamping arms 340 to move closer to or away from each other. More specifically, the third driving device is a third telescopic cylinder 320. One end of the third telescopic cylinder 320 is connected to one of the clamping arms 340 by bolts, and the other end of the third telescopic cylinder 320 is connected to the other clamping arm 340. When the telescopic rod of the third telescopic cylinder 320 shortens, the two clamping arms 340 move closer to each other, and the mold 510 is stably clamped by the clamping blocks 350.

[0103] Moreover, the clamping arm 340 is provided with a brake cylinder 330. The brake cylinder 330 is installed on the clamping arm 340 by bolts, and the brake cylinder 330 is provided with a movable end that can abut against the fixed frame 310. The brake cylinder 330 can be a pneumatic butterfly brake.

[0104] After the two clamping arms 340 clamp the mold 510 through the clamping blocks 350, the brake cylinder 330 can hold the first slide rail 311 of the fixed frame 310 tightly, that is, the movable end of the brake cylinder 330 abuts against the first slide rail 311 of the fixed frame 310, prompting the two clamping arms 340 to be relatively stable with respect to the fixed frame 310, thereby preventing the clamping arms 340 from moving left and right relative to the fixed frame 310 during the operation of the fifth driving device 100, resulting in severe shaking of the mold 510, and greatly improving the stability of the clamping mechanism 300 when clamping and transporting the mold 510.

[0105] Of course, the third driving device can be a telescopic cylinder, a lead screw driving mechanism or a linear module, respectively driving each clamping arm 340 to move linearly.

[0106] The fifth driving device 100 is connected to the fourth driving device 200 to drive the fourth driving device 200 to move in the left - right direction. More specifically, the fifth driving device 100 includes a frame 700, a translation frame 110 and a first motor 120.

[0107] The frame 700 is provided with a transmission member 800. The two ends of the transmission member 800 extend in the left - right direction, and the left end and the right end of the transmission member 800 can be fixed to the frame 700 by bolts.

[0108] The bottom of the translation frame 110 is provided with traveling wheels 111. Correspondingly, a guide rail extending in the left - right direction is provided on the frame 700. The guide rail is located at the top of the frame 700. By rolling the traveling wheels 111 along the length direction of the guide rail, the connection between the translation frame 110 and the frame 700 is realized and the translation frame 110 can move in the left - right direction. Of course, the sliding rail and slider method can also be used to realize the movable connection between the translation frame 110 and the frame 700.

[0109] The first motor 120 is provided on the translation frame 110 through bolts and can move together with the translation frame 110. The first motor 120 is a forward and reverse motor, and the output shaft of the first motor 120 can rotate clockwise or counterclockwise. A transmission wheel 130 is provided on the output shaft of the first motor 120, and the transmission member 800 is wound around the transmission wheel 130. The transmission member 800 can be a chain, and correspondingly, the transmission wheel 130 is a sprocket. The transmission member 800 can also be a timing belt, and correspondingly, the transmission wheel 130 is a timing belt pulley. The first motor 120 can be a servo motor.

[0110] When the output shaft of the first motor 120 drives the transmission wheel 130 to rotate, the transmission wheel 130 can move linearly relative to the transmission member 800, so as to realize the left or right movement of the translation frame 110 relative to the frame 700.

[0111] In addition, a transition wheel 140 can be provided on both the left and right sides of the transmission wheel 130. The transition wheel 140 can be provided on the translation frame 110. In this embodiment, the transition wheel 140 is located below the transmission wheel 130, and the transmission member 800 is also wound around the transition wheel 140. In this way, the contact area between the transmission member 800 and the transmission wheel 130 can be increased, prompting the transmission member 800 to be tightly connected to the transmission wheel 130 and improving the transmission efficiency.

[0112] In this embodiment, as Figure 4 shown, two transmission members 800 are provided. The first motor 120 is drivingly connected to a first transmission shaft 170 through a speed reducer. Transmission wheels 130 are respectively provided at both ends of the first transmission shaft 170, and the two transmission wheels 130 are respectively connected to the two transmission members 800.

[0113] Of course, it is not excluded that the fifth driving device 100 uses a telescopic cylinder or a lead screw driving mechanism to drive the translation frame 110 to move. The fourth driving device 200 is provided on the translation frame 110 and can move left or right together with the translation frame 110.

[0114] The fourth driving device 200 is connected to the fixed frame 310 to drive the fixed frame 310 to move in the up and down direction. More specifically, the fourth driving device 200 includes a second motor 210, a second driven wheel 240, a first chain 231, a third driven wheel 261, a second chain 232, a fourth driven wheel 262, a fifth driven wheel 263, and a third chain 233.

[0115] The second motor 210 is provided on the translation frame 110 through bolts. The second motor 210 is a forward and reverse motor, and its output shaft can rotate clockwise or counterclockwise. The second motor 210 can be a stepper motor. A first driven wheel 220 is provided on the output shaft of the second motor 210.

[0116] The second driven wheel 240 is disposed on the translation frame 110 through a bearing seat and can rotate around its horizontal axis. The third driven wheel 261 is disposed on the translation frame 110 through a bearing seat and can rotate around its horizontal axis. In this embodiment, the third driven wheel 261 is located below the second driven wheel 240. The fourth driven wheel 262 is disposed on the translation frame 110 through a bearing seat and can rotate around its horizontal axis. The fifth driven wheel 263 is disposed on the translation frame 110 through a bearing seat and can rotate around its horizontal axis. In this embodiment, the fourth driven wheel 262 is located on the left side of the fifth driven wheel 263.

[0117] The first driven wheel 220 , the second driven wheel 240 , the third driven wheel 261 , the fourth driven wheel 262 and the fifth driven wheel 263 are all sprockets.

[0118] The first chain 231 is wound between the first driven wheel 220 and the second driven wheel 240. One end of the second chain 232 is connected to the first chain 231, and the other end of the second chain 232 is connected to one end of the fixing frame 310, and the second chain 232 is wound around the third driven wheel 261. One end of the third chain 233 is connected to the first chain 231, and the other end of the third chain 233 is connected to the other end of the fixing frame 310, and the third chain 233 is wound around the fourth driven wheel 262 and the fifth driven wheel 263.

[0119] In this embodiment, the two ends of the first chain 231 are respectively connected to the chain connecting plate 250 by welding or bolts, the upper end of the second chain 232 is fixed to the chain connecting plate 250 by welding or bolts, and the upper end of the third chain 233 is also fixed to the chain connecting plate 250 by welding or bolts.

[0120] Of course, the two ends of the first chain 231 may be connected in a closed loop, and the upper end of the second chain 232 and the upper end of the third chain 233 may be fixed to the first chain 231 by welding.

[0121] In this embodiment, if Figure 4 As shown, the second motor 210 is connected to a second transmission shaft 270 through a reducer, and the first driven wheels 220 are respectively arranged at both ends of the second transmission shaft 270. Correspondingly, two second driven wheels 240, two third driven wheels 261, two fourth driven wheels 262 and two fifth driven wheels 263 are each arranged, and two first chains 231, two second chains 232 and two third chains 233 are each arranged.

[0122] like Figure 3As shown, when the output shaft of the second motor 210 drives the first driven wheel 220 to rotate clockwise, the upper ends of the second chain 232 and the third chain 233 move leftward due to the clockwise operation of the first chain 231, causing the lower ends of the second chain 232 and the third chain 233 to move downward, thereby realizing the lowering of the fixed frame 310 of the clamping mechanism 300.

[0123] Conversely, when the first driven wheel 220 rotates counterclockwise, the upper ends of the second chain 232 and the third chain 233 move rightward due to the counterclockwise operation of the first chain 231, causing the lower ends of the second chain 232 and the third chain 233 to move upward, thereby realizing the rising of the fixed frame 310 of the clamping mechanism 300.

[0124] Moreover, a positioning guide wheel 312 is provided at the top of the fixed frame 310. One or more positioning guide wheels 312 can be provided. The axis of the positioning guide wheel 312 extends in the front-rear direction. The positioning guide wheel 312 is installed on the fixed frame 310 through a bearing seat, and the positioning guide wheel 312 can rotate around its axis.

[0125] A connecting frame 150 is provided at the bottom of the translation frame 110. The bottom surface of the connecting frame 150 is recessed upward to form a positioning groove 160. Moreover, a chamfer is provided at the notch of the positioning groove 160. The chamfer plays a guiding role to facilitate the insertion of the positioning guide wheel 312 into the positioning groove 160.

[0126] When the fixed frame 310 rises under the pulling force of the second chain 232 and the third chain 233, the positioning guide wheel 312 can accurately insert into the positioning groove 160 under the guiding action of the chamfer and be adaptively connected with the positioning groove 160, causing the fixed frame 310 to be relatively stable with respect to the translation frame 110. Thus, during the process of the translation frame 110 moving in the left-right direction, the fixed frame 310 does not shake left and right relative to the translation frame 110, thereby preventing the fixed frame 310 from causing harm to surrounding equipment or personnel. Moreover, it helps to improve the working efficiency of the clamping manipulator and quickly clamp and transport the mold 510 onto the conveying mechanism 600.

[0127] Since the second chain 232 and the third chain 233 are flexible, during the process of the translation frame 110 driving the fixed frame 310 to move left or right, the fixed frame 310 will shake left and right due to its inertia. Especially when the clamping mechanism 300 clamps a relatively heavy mold 510, the shaking of the clamping mechanism 300 may lead to relatively large accidents. Therefore, the positioning guide wheel 312 and the positioning groove 160 are provided, and the left and right movement of the positioning guide wheel 312 is restricted through the positioning groove 160, thereby realizing the relative stability of the fixed frame 310 with respect to the translation frame 110.

[0128] Of course, the fourth driving device 200 can also be a hydraulic cylinder, a telescopic air cylinder or a screw driving mechanism.

[0129] In addition, a robotic arm with more than four axes can be used to replace the combination of the fourth driving device 200 and the fifth driving device 100.

[0130] As Figure 1 , Figure 2 , Figure 9 and Figure 10 shown, the mold conveyor 900 conveys the mold 510 to the clamping robotic arm. A position detector such as a photoelectric switch can be set to position the mold 510 on the mold conveyor 900 to ensure that the mold 510 is conveyed in place and the conveying action is stopped. The mold conveyor 900 can be a roller conveyor or a chain conveyor.

[0131] Then, the clamping robotic arm is enabled. Driven by the fifth driving device 100, the clamping mechanism 300 moves above the mold 510 and, driven by the fourth driving device 200, the clamping mechanism 300 descends a certain height to accurately and stably clamp the mold 510. Immediately afterwards, the clamping mechanism 300 drives the mold 510 to rise to a set height position under the action of the fourth driving device 200; subsequently, the fifth driving device 100 drives the clamping mechanism 300 to drive the mold 510 to move horizontally above the conveying mechanism 600 to complete placing the mold 510 on the upper surface of the mold base plate 520 of the conveying mechanism 600.

[0132] The conveying mechanism 600 conveys the mold base plate 520 coming out of the firing kiln towards the centering mechanism 400. Similarly, a position detector such as a photoelectric switch can be set to position the mold 510 on the conveying mechanism 600 to ensure that the mold base plate 520 is conveyed in place. At this time, the clamping robotic arm places the mold 510 on the mold base plate 520. After the clamping robotic arm releases the mold 510, the centering mechanism 400 is started. Through the first centering component and the second centering component, the mold 510 and the mold base plate 520 are centered in the left-right direction and the front-back direction, prompting the mold 510 to be located at the center position of the mold base plate 520, and finally completing the automatic mold closing work of the mold 510 and the mold base plate 520.

[0133] Finally, the conveying mechanism 600 conveys the mold 510 and the mold base plate 520 after mold closing to the firing kiln.

[0134] Of course, in actual operation, it can also be that the clamping mechanism 300 drives the mold 510 to descend to a certain height, such as 20 millimeters above the upper surface of the mold base plate 520, and then the centering mechanism 400 is started. After the centering work is completed, the clamping mechanism 300 releases the mold 510, enabling the mold 510 to fall on the mold base plate 520. Since the mold 510 is relatively heavy, it is not easy to shift during the falling process, and the purpose of automatically closing the mold 510 and the mold base plate 520 can be achieved.

[0135] The preferred embodiments of the present invention have been specifically described above. However, the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
