The conveying mechanism 600 may be a chain conveyor, a roller conveyor, or otherwise. In this embodiment, the mold 510 is a PVC mold, and after the mold is closed, the mold 510 is located at the center of the upper surface of the mold base 520. The mold 510 is a square block and the mold bottom plate 520 is a square plate. The mold 510 may be, but is not limited to, a refractory casting mold.

After the two clamping arms 340 clamp the mold 510 through the clamping blocks 350, the brake cylinder 330 can tightly hold the first slide rail 311 of the fixing frame 310, that is, the movable end of the brake cylinder 330 abuts against the first slide rail 311 of the fixing frame 310, so that the two clamping arms 340 are stable and immovable relative to the fixing frame 310, thereby preventing the mold 510 from shaking violently due to the fact that the clamping arms 340 move left and right relative to the fixing frame 310 when the fifth driving device 100 operates, and greatly improving the stability of the clamping mechanism 300 in clamping the mold 510 and carrying.

Of course, the third driving device may be a telescopic cylinder, a screw rod driving mechanism or a linear module, and respectively drives each of the clamping arms 340 to move linearly.

The first chain 231 is wound between the first driven pulley 220 and the second driven pulley 240. One end of the second chain 232 is connected to the first chain 231, 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, 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.

Of course, both end portions of the first chain 231 may be connected in a closed loop, and the upper end portion of the second chain 232 and the upper end portion of the third chain 233 may be fixed to the first chain 231 by welding.

In this embodiment, as shown in fig. 4, the second motor 210 is in transmission connection with one second transmission shaft 270 through a speed reducer, the first driven wheel 220 is respectively disposed at two 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 disposed, and two first chains 231, two second chains 232 and two third chains 233 are disposed.

As shown in fig. 3, when the output shaft of the second motor 210 drives the first driven wheel 220 to rotate clockwise, the upper end of the second chain 232 and the upper end of the third chain 233 move to the left due to the clockwise rotation of the first chain 231, so that the lower end of the second chain 232 and the lower end of the third chain 233 move downward, and the fixed frame 310 of the clamping mechanism 300 descends.

Conversely, when the first driven wheel 220 rotates counterclockwise, the upper end of the second chain 232 and the upper end of the third chain 233 move to the right due to the counterclockwise rotation of the first chain 231, so that the lower end of the second chain 232 and the lower end of the third chain 233 move upward, and the fixed frame 310 of the clamping mechanism 300 is lifted.

And, the top of mount 310 is equipped with location guide pulley 312, and location guide pulley 312 can set up one or more, and the axis of location guide pulley 312 extends along fore-and-aft direction, and location guide pulley 312 passes through the bearing frame and installs on mount 310, and location guide pulley 312 can rotate around its axis.

The bottom of translation frame 110 sets up link 150, and the bottom surface of link 150 upwards caves in and forms constant head tank 160, and moreover, the notch department of constant head tank 160 is provided with the chamfer, and the chamfer plays the guide effect, makes things convenient for location guide pulley 312 to insert in the constant head tank 160.

When the fixing frame 310 ascends under the action of the pulling force of the second chain 232 and the third chain 233, the positioning guide wheel 312 can be accurately inserted into the positioning groove 160 through the guiding effect of the chamfer, and is in adaptive connection with the positioning groove 160, so that the fixing frame 310 is stable and immovable relative to the translation frame 110, thereby avoiding the problem that the fixing frame 310 shakes left and right relative to the translation frame 110 in the process of moving the translation frame 110 in the left and right direction, and further preventing the fixing frame 310 from harming surrounding equipment or personnel, and being beneficial to improving the working efficiency of the clamping manipulator, and rapidly clamping and carrying the mold 510 onto the conveying mechanism 600.

Because the second chain 232 and the third chain 233 are flexible, when the translation frame 110 drives the fixed frame 310 to move left or right, the fixed frame 310 may swing left or right due to its inertia, and especially when the clamping mechanism 300 clamps the heavy mold 510, the swinging of the clamping mechanism 300 may cause a large accident, and therefore, the positioning guide wheel 312 and the positioning groove 160 are provided, and the positioning guide wheel 312 is restricted from moving left or right by the positioning groove 160, so that the fixed frame 310 is stable and immovable relative to the translation frame 110.

Of course, the fourth driving device 200 may be a hydraulic cylinder, a telescopic cylinder, or a screw driving mechanism.

Instead of the combination of the fourth driving device 200 and the fifth driving device 100, a four-axis or more robot arm may be used.

As shown in fig. 1, 2, 9 and 10, the mold conveyor 900 conveys the mold 510 to the clamping robot, and a position detector such as an electro-optical switch may be provided to position the mold 510 on the mold conveyor 900 to ensure that the mold 510 is conveyed in place and to stop the conveying action. The mold conveyor 900 may be a roller conveyor or a chain conveyor.

Then, the clamping robot is activated, the clamping mechanism 300 moves to the upper side of the mold 510 under the driving of the fifth driving device 100, and the clamping mechanism 300 descends to a certain height under the driving of the fourth driving device 200, so as to accurately and stably clamp the mold 510. Subsequently, the clamping mechanism 300 lifts up to the set height position with the mold 510 under the action of the fourth driving device 200; subsequently, the fifth driving device 100 drives the clamp mechanism 300 to horizontally move the mold 510 above the conveying mechanism 600 to complete the placement of the mold 510 on the upper surface of the mold bed 520 on the conveying mechanism 600.

The conveying mechanism 600 conveys the mold base 520 from the firing kiln toward the centering mechanism 400. Similarly, a position detector, such as an opto-electronic switch, may be provided to position the mold 510 on the transport mechanism 600 to ensure that the mold bed 520 is transported into position. At this point, the gripper robot places the mold 510 on the mold bed 520, and after the gripper robot releases the mold 510, the centering mechanism 400 is activated. The mold 510 and the mold base 520 are centered in the left-right direction and the front-rear direction by the first centering member and the second centering member, so that the mold 510 is positioned at the center of the mold base 520, and the automatic mold closing work of the mold 510 and the mold base 520 is finally completed.

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

Certainly, in actual operation, the clamping mechanism 300 may also drive the mold 510 to descend to a certain height, for example, a height 20 mm from the upper surface of the mold base plate 520, then the centering mechanism 400 is started, after the centering operation is completed, the clamping mechanism 300 releases the mold 510, so that the mold 510 falls on the mold base plate 520, and since the mold 510 is heavy, the mold 510 is not easily displaced in the falling process, and the purpose of automatically closing the mold 510 and the mold base plate 520 can be achieved.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
