In the mold for producing porous clay bricks, the shaped clay bricks will move downward under the drive of the forming plate, and then be pushed out of the groove of the forming plate under the action of the demoulding cleaning structure, thereby achieving a demoulding effect. In the above-mentioned equipment, the upper mold and the lower mold are opened by moving linearly in the vertical direction.

[0013] A method for using an automatic mold opening and closing mechanism comprises the following steps: S1. After the clay is formed, the motor is started to drive the outer rotating disk, the rotating disk connecting shaft and the toggle rod to rotate. The motor is connected to the active crank at one end, and the other end is connected to the outer rotating disk at the other end through the rotating disk connecting shaft extended by the motor. The outer rotating disk only rotates, and the motor drives the active cranks on both sides to rotate. The active crank drives the driven crank and the inner moving block connected to it to move. In the initial state, the direct-acting column and the rotating column on the inner moving block are both in the direct-acting groove on the fixed side plate. The two active cranks first push the inner moving block upward, which can be regarded as a crank slider mechanism, until the direct-acting column reaches the end of the direct-acting groove. At this time, the two active cranks can no longer push the inner moving block upward, and the rotating column is at the connection between the direct-acting groove and the rotating groove. At this time, it can be regarded as a crank rocker mechanism. The two active cranks continue to push the inner moving block The rotating column will move along the rotating groove and drive the inner moving block to rotate with the axis of the linear column as the center. The inner moving blocks on both sides are connected by the bracket mounting arm and the moving block connecting rod to ensure synchronous movement and rotation of the two sides. When the inner moving block rotates, the bracket mounting arm is installed with the upper mold connecting arm through the bracket mounting bolt, and the upper mold connecting arm is installed with the connecting plug block through the connecting groove. The connecting plug block is connected to the upper mold of the mold through the plug block connecting bolt on the mold opening vibration mechanism, and the part where the connecting plug block is connected to the connecting groove is a semicircular rectangle and cannot rotate. The upper mold connecting arm always remains parallel to the upper mold of the mold, so that the bracket mounting arm will drive the upper mold of the mold to rotate through the upper mold connecting arm during the rotation of the inner moving block, realizing the movement process of the upper mold of the mold first rising and then turning over, thereby leaving the top space vacant, which is convenient for dumping the mold to facilitate cleaning and maintenance. S2. When the motor drives the outer rotating disk to rotate, it also drives the toggle rod on its surface to rotate. In the initial state, the toggle rod is far away from the lower die toggle groove on the lower die of the mold, but the toggle rod will still follow the rotation and gradually approach the lower die toggle groove until the direct-acting column reaches the end of the direct-acting groove and the toggle rod contacts the lower die toggle groove. At this time, the toggle rod continues to rotate with the outer rotating disk and presses down the lower die toggle groove, driving the lower die toggle groove to slide downward on the path limit ring and compressing the rotation reset spring, thereby driving the lower die of the mold to flip downward. When the motor is reversed, the toggle rod no longer presses down the lower die toggle groove, and the rotation reset spring drives the lower die toggle groove and the lower die of the mold to reset; S3. During the movement of the upper die of the mold, since the upper die of the mold and the connecting plug block are not directly connected, but are installed through the plug block connecting bolts, the connecting plug block is installed inside the vibration installation groove and can slide up and down with the plug block connecting bolts. Since the height position of the connecting plug block is fixed following the upper die connecting arm and the inner moving block, and the relative position of the connecting plug block and the upper die of the mold is not fixed, the upper die of the mold can move up and down in a small range by itself during the upward movement of the upper die connecting arm and the inner moving block. During the upward movement of the connecting plug block, the driven gear connected to its rotation on the outer side is meshed with the fixed rack on the fixed side plate, and the driven gear drives the external driven cam to rotate, and the driven cam continuously lifts and lowers the driven connection on the upper die of the mold, so that the upper die of the mold vibrates up and down periodically, and the plug block vibration spring is distributed between the plug block connecting bolts and the vibration installation groove, so that the vibration curve is smoother, which is convenient for demolding the molded clay; S4. The upper die of the mold is clamped on the direct-acting mounting block through the upper die connecting ring and the extrusion block and can be disconnected. The outer surface of the extrusion block is two inclined planes. The top inclined plane contacts the upper die connecting ring. When the upper die of the mold moves downward, the upper die connecting ring enters from the smaller end of the extrusion block, presses the extrusion block into the direct-acting mounting block and compresses the internal extrusion reset spring until it is separated from the top inclined plane of the extrusion block. The extrusion reset spring drives the extrusion block to reset. At this time, the bottom of the upper die connecting ring is placed on the limiting ring of the mounting block and the top is blocked by the bottom of the top inclined plane of the extrusion block, so that the upper die of the mold passes through the upper die. The die connecting ring is connected to the direct-acting mounting block. When the upper die of the die moves upward, it will first drive the direct-acting mounting block to move upward together. At this time, the lower die extrusion shell on the lower die of the die contacts the bottom inclined plane on the extrusion block. The more the direct-acting mounting block moves upward, the deeper it is pressed by the lower die extrusion shell until it is completely sunk inside. At this time, the upper die connecting ring is no longer restricted by the bottom of the top inclined plane on the extrusion block and falls off from the direct-acting mounting block. The upper die of the die is not connected to the direct-acting mounting block at this time. The direct-acting mounting block moves in the lower die mounting groove inside the lower die of the die and extends outward, so that the extrusion block is linked with the external structure. The direct-acting mounting The moving path of the block is limited by the lower die mounting groove and the spring mounting column. The top force storage spring will be squeezed during the upward movement of the direct-acting mounting block. At this time, the pop-up base on the top of the force storage spring is stuck by the top rotating block. The top rotating block is perpendicular to the pop-up base at this time. The upward force of the pop-up base and the collinear angle of the top rotating block are zero. At this time, the force storage spring is blocked by the pop-up base and cannot rise. It can only be compressed and stored. As the direct-acting mounting block continues to rise, the adjustable pulling shaft contacts the pulling arm, and the pulling arm is driven to rise. Because it is hinged, an oblique upward force can be used from the side. Since it is not collinear with the force arm The top dead rotating block can be pulled, and the top dead rotating block rotates outward and no longer blocks the pop-up base. The compressed force of the stored force spring is released, driving the pop-up base to pop up quickly and lift up the top tool mounting seat. The tool mounting seat is slidably connected in the oblique oblique groove, and during the rising process, it will move toward the inside of the lower mold of the mold, driving the trimming tool to quickly eject inward and obliquely upward, and scrape off the excess clay material bonded to the upper mold of the mold. When the upper mold of the mold moves downward, it will be connected to the direct-acting mounting block again through the upper mold connecting ring and contact the mounting block limit ring, pressing it down to restore the entire mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the setting of the mold opening and dumping mechanism, the motor drives the crank structure to move on a fixed path, driving the upper mold to first rise and then rotate, so that the space above the lower mold can be vacated, and compared with direct rotation, rising first and then rotating can prevent the collision between the upper and lower molds, and after rising to a specified height, the lower mold is also flipped, which is convenient for dumping the residual clay inside the lower mold, and convenient for cleaning and maintenance of the upper and lower molds before and after use.

[0015] In the present invention, by setting the mold opening vibration mechanism, during use, when the upper mold is moving, the gear rack drives the cam mechanism to vibrate the upper mold, so that the clay adhered to the surface due to solidification falls off or loosens, which is convenient for subsequent cleaning.

[0016] In the present invention, by setting a pop-up trimming mechanism, during use, the upper mold is moved, the internal spring is compressed and stored, and is released when it moves to a required height, so that the blade hidden inside pops up to scrape off the burrs on the surface of the clay after molding.

The rear section is a semicircular rectangle inserted into the semicircular rectangular connecting groove 3111, which can prevent its rotation so that the upper mold connecting arm 311 always maintains a relative position with the upper mold 2 of the mold. The path limiting ring 314 limits the displacement path of the lower mold toggle groove 313 and the lower mold 1 of the mold, so that it rotates and a rotation reset spring 315 can be installed on its surface for reset.

[0023] The mold opening vibration mechanism 4 includes a fixed rack 41, which is fixedly connected to the outer surface of the fixed side plate 31, and vibration installation grooves 42 are provided on both sides of the upper mold 2 of the mold. The inner surface of the vibration installation groove 42 is fixedly connected with a plug-in block connecting bolt 421, and the outer surface of the plug-in block connecting bolt 421 is sleeved with a plug-in block vibration spring 422. The outer surface of the plug-in block connecting bolt 421 is slidably connected to the connecting plug 312, and one end of the connecting plug 312 is rotatably connected with a driven gear 43, and the outer surface of the driven gear 43 is fixedly connected with a driven cam 44, and the top surface of the upper mold 2 of the mold is fixedly connected with a driven connecting frame 45. During the use of the mold opening vibration mechanism 4, the upper mold connecting arm 311 is not directly connected to the upper mold 2 of the mold. The connection is then made through the connecting plug block 312 and the plug block connecting bolt 421. The plug block connecting bolt 421 can slide on the connecting plug block 312 to drive the mold upper mold 2 to slide up and down. When the upper mold connecting arm 311 drives the mold upper mold 2 to move upward, the driven gear 43 on the connecting plug block 312 engages with the fixed rack 41 on the fixed side plate 31 to convert the linear movement into rotation, and drives the driven cam 44 connected to the driven gear 43 to rotate. During the rotation process, the multiple protrusions on the surface of the driven cam 44 will alternately hit the driven connecting frame 45 on the top of the mold upper mold 2, so that it drives the mold upper mold 2 to continuously rise and fall, thereby generating vibration on the mold upper mold 2, thereby facilitating the falling off of the clay adhering to the mold upper mold 2.

[0024] The cross section of the vibration installation groove 42 is a semicircular rectangle. The vibration installation groove 42 is slidably connected to the outer surface of the connecting plug block 312. The number of plug block vibration springs 422 on each plug block connecting bolt 421 is two, and the two plug block vibration springs 422 are symmetrically distributed with the central axis of the connecting plug block 312 as the symmetry axis. The plug block vibration spring 422 and the outer side of the connecting plug block 312 and the inner side surface of the vibration installation groove 42 are all in contact with each other. The driven gear 43 and the driven cam 44 are both rotatably connected to the outer side surface of the connecting plug block 312, and the outer side surface of the driven cam 44 is in contact with the driven connecting frame 45. The bottom surface is slidably connected, and there are two driven connecting frames 45, and the two driven connecting frames 45 are symmetrically distributed with the central axis of the upper mold 2 of the mold as the symmetry axis. The lateral dimension of the vibration mounting groove 42 is the same as that of the connecting plug 312, while the longitudinal dimension is lengthened, so that the connecting plug 312 can move vertically in the vibration mounting groove 42. The upper and lower plug vibration springs 422 allow the connecting plug 312 to be in the center position, and there is enough space when moving up and down. The symmetrical driven connecting frames 45 and the driven cam 44 vibrate simultaneously on both sides to increase strength and disperse force.

[0025] The pop-up trimming mechanism 5 includes an upper die connecting ring 51, which is fixedly connected to the outer surface of the upper die 2 of the die, a lower die mounting groove 52 is provided on the inner surface of the lower die 1 of the die, an oblique groove 521 is provided on the inner surface of the lower die mounting groove 52, a spring mounting column 53 is fixedly connected to the inner surface of the lower die mounting groove 52, a force storage spring 54 is sleeved on the outer surface of the spring mounting column 53, a direct-acting mounting block 55 is slidably connected to the outer surface of the spring mounting column 53, a mounting block limiting ring 551 is fixedly connected to the outer surface of the direct-acting mounting block 55, an extrusion block 552 is slidably connected to the inner surface of the direct-acting mounting block 55, an extrusion reset spring 553 is fixedly connected to the outer surface of the extrusion block 552, and the outer surface of the direct-acting mounting block 55 is fixedly connected to the outer surface of the extrusion block 552. An adjustable pulling shaft 56 is bolted, a pulling arm 57 is slidably connected to the inner surface of the direct-acting mounting block 55, the other end of the pulling arm 57 is hingedly connected to a top-dead rotating block 58, the other end of the top-dead rotating block 58 is rotatably connected to a rotating block rotating shaft 59, the outer surface of the lower die 1 of the mold is fixedly connected to a lower die extrusion shell 510, the inner surface of the lower die mounting groove 52 is slidably connected to a pop-up base 511, the outer surface of the pop-up base 511 is fixedly connected to a connecting pin 5111, the top surface of the lower die mounting groove 52 is slidably connected to a tool mounting seat 512, the bottom surface of the tool mounting seat 512 is provided with a connecting slide groove 5121, the top surface of the tool mounting seat 512 is fixedly connected to a trimming tool 513, and a trimming mechanism 5 is popped out. When the upper die 2 of the mold is in use, it is stuck on the direct-acting mounting block 55 through the upper die connecting ring 51 and the extrusion block 552 and can be disconnected. When the upper die 2 of the mold is pressed down, the extrusion block 552 with an inclined plane surface is pressed into and connected to it by the reset action of the extrusion reset spring 553. When the upper die 2 of the mold rises, the direct-acting mounting block 55 is pulled up, and after moving for a period of time, it is disconnected under the pressing and reset action of the extrusion block 552 and the lower die extrusion shell 510, so as to prevent the pop-up trimming mechanism 5 from moving further upward, resulting in too many top parts affecting subsequent use. During the upward movement of the direct-acting mounting block 55, the force storage spring 54 will be compressed with the pop-up base 511. In the initial state, the pop-up base 511 will pass the rotation point of the dead rotating block 58 due to the upward movement. The movable base 511 is locked until the adjustable pulling shaft 56 on the linear mounting block 55 uses the pulling arm 57 to pull the locking rotating block 58 away from the side and no longer locks the pop-up base 511. The force storage spring 54 releases the pressure to push the pop-up base 511 upward. The pulling arm 57 does not slide in the linear mounting block 55 before contacting the adjustable pulling shaft 56. The adjustable pulling shaft 56 is connected to the linear mounting block 55 by bolts to change the height to adjust the time of triggering the locking rotating block 58 to adapt to different mold depths. The pop-up base 511 ejects and lifts the top tool mounting seat 512. The tool mounting seat 512 moves inward along the oblique groove 521 at the same time during the lifting process, driving the trimming tool 513 to cut the burrs of the molded clay after cooling.The pop-up base 511 is connected to the connecting slot 5121 on the tool mounting seat 512 through the connecting pin 5111. The connecting pin 5111 can slide in the connecting slot 5121 to adapt to the lateral movement of the tool mounting seat 512. In this way, when the pop-up base 511 is reset, it will pull the tool mounting seat 512 to reset and be stored inside the lower mold 1 of the mold. The ejection trigger of the pop-up trimming mechanism 5 is controlled by the adjustable pulling shaft 56. When the adjustable pulling shaft 56 is moved downward, the trigger time becomes longer. When it is at the bottom, the trigger time exceeds the time for the upper mold connecting ring 51 to separate from the direct-acting mounting block 55, and the pop-up part will not be triggered, which is convenient for cleaning and testing when the lower mold 1 and the upper mold 2 of the mold are separated.

The spring mounting column 53 limits the moving path of the direct-acting mounting block 55 and the pop-up base 511 while installing the force storage spring 54 to prevent the position from shifting. The direct-acting mounting block 55 slides in the lower mold mounting groove 52 and partially extends the extrusion block 552. The two inclined planes of the extrusion block 552 respectively control the connection, locking and separation. The pop-up base 511 is connected to the connecting groove 5121 on the tool mounting seat 512 through the connecting pin 5111. The connecting pin 5111 can slide in the connecting groove 5121 to adapt to the lateral movement of the tool mounting seat 512.

[0027] In this embodiment, Figure 1As shown, the fixed side plate 31 is installed on both sides of the upper mold 2 and the lower mold 1 of the mold. The upper mold 2 and the lower mold 1 of the mold are in contact but not directly connected. They are connected through the mold opening and dumping mechanism 3. The direct-acting mounting block 55 slides in the lower mold mounting groove 52 and partially extends the extrusion block 552. The driven gear 43 is meshed with the fixed rack 41 on the fixed side plate 31; In this embodiment, Figure 2 As shown, the outer rotating disk 35 and the inner active crank 37 are driven to rotate by the motor 34, the direct-acting groove 32 and the rotating groove 33 intersect, and the inner moving block 39 is connected to the direct-acting groove 32 on the fixed side plate 31 through the direct-acting column 391 and the rotating column 392. At this time, the inner moving block 39 is at the bottom initial position, the upper mold 2 and the lower mold 1 are closed, and the position of the toggle rod 36 is at a certain distance from the lower mold toggle groove 313. At this time, the rotation will not contact the lower mold toggle groove 313, and the path limiting ring 314 is a third of a circle, and the path limiting ring 314 passes through the lower mold toggle groove 313; In this embodiment, Figure 3 As shown, the inner moving blocks 39 are symmetrically distributed and connected to the bracket mounting arm 310 through the moving block connecting rod 393. The driven crank 38 is rotationally connected to the inner moving block 39 but penetrated by the moving block connecting rod 393. At this time, the inner moving block 39 moves to the top, the direct-acting column 391 reaches the end of the direct-acting groove 32, and the rotating column 392 is at the connection between the direct-acting groove 32 and the rotating groove 33. The upper mold connecting arm 311 rises to the top but does not rotate, and at this time, the toggle rod 36 contacts the lower mold toggle groove 313. In this embodiment, Figure 4 As shown, the connection groove 3111 on the upper mold connecting arm 311 is a semicircular rectangle, the front end of the connecting plug 312 is a cylinder and the rear end is a semicircular rectangle, and the vibration installation groove 42 is also a semicircular rectangle with the same transverse dimension as the connecting plug 312 and a longer longitudinal dimension. At this time, the motor 34 continues to rotate the active crank 37 to push the driven crank 38, and the rotating column 392 cannot be pushed upward, so it is pushed from the side to rotate, and the inner moving block 39 is driven to rotate to realize the upward flipping and opening of the upper mold 2 of the mold, and at the same time, the toggle rod 36 at the bottom presses the lower mold toggle groove 313 downward, and the lower mold 1 of the mold is also flipped downward; In this embodiment, Figure 5 As shown, the upper die connecting arm 311 is fixedly connected to the bracket mounting arm 310 through the bracket mounting bolt 3101, the driven gear 43 is meshed with the fixed rack 41 on the fixed side plate 31, and the driven connecting frame 45 is symmetrically distributed on the upper die 2 of the mold; In this embodiment, Figure 6As shown, the upper mold connecting arm 311 is not directly connected to the mold upper mold 2 but is connected through the connecting plug block 312 and the plug block connecting bolt 421. The plug block connecting bolt 421 can slide on the connecting plug block 312 to drive the mold upper mold 2 to slide up and down. The transverse dimension of the vibration installation groove 42 is the same as that of the connecting plug block 312, but the longitudinal dimension is lengthened, so that the connecting plug block 312 can move vertically in the vibration installation groove 42. In this embodiment, Figure 7 As shown, a lower die mounting groove 52 is provided on the inner surface of the lower die 1 of the mold, the direct-acting mounting block 55 slides in the lower die mounting groove 52 and partially extends the extrusion block 552, and the spring mounting column 53 penetrates the direct-acting mounting block 55 and the pop-up base 511; In this embodiment, Figure 8 As shown, the direct-acting mounting block 55 will compress the force storage spring 54 with the pop-up base 511 during the upward movement. In the initial state, the pop-up base 511 will pass the rotation point of the top-locking rotating block 58 due to the upward movement, resulting in being stuck, until the adjustable pulling shaft 56 on the direct-acting mounting block 55 pulls the top-locking rotating block 58 away from the side and no longer sticks to the pop-up base 511, and the force storage spring 54 releases the pressure to push the pop-up base 511 to move upward; In this embodiment, Fig. 9 As shown, the upper die 2 of the mold is clamped on the direct-acting mounting block 55 through the upper die connecting ring 51 and the extrusion block 552 and can be disconnected.

[0028] A method for using an automatic mold opening and closing mechanism comprises the following steps: S1. After the clay is formed, the motor 34 is started to drive the outer rotating disk 35, the rotating disk connecting shaft 351 and the toggle rod 36 to rotate. The motor 34 is connected to the active crank 37 at one end, and the other end is connected to the outer rotating disk 35 at the other end through the rotating disk connecting shaft 351 extended by the motor 34. The outer rotating disk 35 only rotates, and the motor 34 drives the active cranks 37 on both sides to rotate. The active crank 37 drives the driven crank 38 and the inner moving block 39 connected thereto to move. In the initial state, The direct-acting column 391 and the rotating column 392 on the inner moving block 39 are both in the direct-acting groove 32 on the fixed side plate 31. The two active cranks 37 first push the inner moving block 39 to move upward, which can be regarded as a crank slider mechanism, until the direct-acting column 391 reaches the end of the direct-acting groove 32. At this time, the two active cranks 37 cannot continue to push the inner moving block 39 upward. At the same time, the rotating column 392 is at the connection between the direct-acting groove 32 and the rotating groove 33. At this time, the two active cranks 37 of the crank rocker mechanism continue to push the inner moving block 39. 9, the rotating column 392 will move along the rotating groove 33, and drive the inner moving block 39 to rotate with the axis of the direct-acting column 391 as the center. The inner moving blocks 39 on both sides are connected by the bracket mounting arm 310 and the moving block connecting rod 393 to ensure synchronous movement and rotation of the two sides. When the inner moving block 39 rotates, the bracket mounting arm 310 is installed with the upper mold connecting arm 311 through the bracket mounting bolt 3101, and the upper mold connecting arm 311 is installed with the connecting plug 312 through the connecting groove 3111. The connecting plug 312 is connected by the mold opening vibration. The plug-in block connecting bolt 421 on the moving mechanism 4 is connected to the upper mold 2 of the mold, and the portion where the connecting plug-in block 312 is connected to the connecting groove 3111 is a semicircular rectangle and cannot rotate, so the upper mold connecting arm 311 always remains parallel to the upper mold 2 of the mold, so that the bracket mounting arm 310 drives the upper mold 2 of the mold to rotate through the upper mold connecting arm 311 during the rotation of the inner moving block 39, realizing the movement process of the upper mold 2 of the mold first rising and then turning over, thereby leaving the top space vacant, making it easy to dump the mold for easy cleaning and maintenance; S2, the process of the motor 34 driving the outer rotating disk 35 to rotate will also drive the toggle rod 36 on its surface to rotate. In the initial state, the toggle rod 36 is away from the lower mold toggle groove 313 on the lower mold 1 of the mold, but the toggle rod 36 will still follow the rotation and gradually approach the lower mold toggle groove 313 until the direct-acting column 391 reaches the end of the direct-acting groove 32, and the toggle rod 36 contacts the lower mold toggle groove 313. At this time, the toggle rod 36 continues to follow the rotation of the outer rotating disk 35 and presses down the lower mold toggle groove 313, driving the lower mold toggle groove 313 to slide downward on the path limit ring 314 and compress the rotation return spring 315, thereby driving the lower mold 1 of the mold to flip downward. When the motor 34 is reversed, the toggle rod 36 no longer presses down the lower mold toggle groove 313, and the rotation return spring 315 drives the lower mold toggle groove 313 and the lower mold 1 of the mold to reset; S3, during the movement of the mold upper mold 2, since the mold upper mold 2 is not directly connected to the connecting plug block 312, but is installed through the plug block connecting bolt 421, the connecting plug block 312 is installed inside the vibration installation groove 42 and can slide up and down on the plug block connecting bolt 421. Since the height position of the connecting plug block 312 is fixed with the upper mold connecting arm 311 and the inner moving block 39, and the relative position of the connecting plug block 312 and the mold upper mold 2 is not fixed, the mold upper mold 2 can move up and down on the upper mold connecting arm 311 and the inner moving block 39. During the process, the connecting block 312 moves up and down in a small range. During the upward movement of the connecting block 312, the driven gear 43 connected to the connecting block on the outside is meshed with the fixed rack 41 on the fixed side plate 31. The driven gear 43 drives the external driven cam 44 to rotate. The driven cam 44 continuously lifts up and down the driven connection on the upper mold 2 of the mold, so that the upper mold 2 of the mold vibrates up and down periodically. The block vibration spring 422 is distributed between the block connection bolt 421 and the vibration installation slot 42, so that the vibration curve is smoother, which is convenient for demolding the molded clay. S4, the upper die 2 of the mold is clamped on the direct-acting mounting block 55 through the upper die connecting ring 51 and the extrusion block 552 and can be disconnected. The outer surface of the extrusion block 552 is two inclined planes, and the top inclined plane contacts the upper die connecting ring 51. When the upper die 2 of the mold moves downward, the upper die connecting ring 51 enters from the smaller end of the extrusion block 552, presses the extrusion block 552 into the direct-acting mounting block 55 and compresses the internal extrusion reset spring 553 until it is separated from the top inclined plane of the extrusion block 552. The extrusion reset spring 553 drives the extrusion block 552 to reset. At this time, the bottom of the upper die connecting ring 51 is placed on the mounting block limit ring 551 and the top is blocked by the bottom of the top inclined plane of the extrusion block 552, so that the mold The upper die 2 is connected to the direct-acting mounting block 55 through the upper die connecting ring 51. When the upper die 2 of the mold moves upward, it will first drive the direct-acting mounting block 55 to move upward together. At this time, the lower die extrusion shell 510 on the lower die 1 of the mold contacts the bottom inclined plane of the extrusion block 552. The more the direct-acting mounting block 55 moves upward, the deeper it is pressed into by the lower die extrusion shell 510 until it is completely sunk into the interior. At this time, the upper die connecting ring 51 is no longer restricted by the bottom of the top inclined plane of the extrusion block 552 and falls off from the direct-acting mounting block 55. The upper die 2 of the mold is not connected to the direct-acting mounting block 55 at this time. The direct-acting mounting block 55 moves in the lower die mounting groove 52 inside the lower die 1 of the mold and extends outward, so that the extrusion block 552 is linked to the external structure. The moving path of the direct-acting mounting block 55 is limited by the lower mold mounting groove 52 and the spring mounting column 53. The direct-acting mounting block 55 will squeeze the top force storage spring 54 during its upward movement. At this time, the pop-up base 511 on the top of the force storage spring 54 is blocked by the locking rotating block 58, and the locking rotating block 58 is perpendicular to the pop-up base 511. The upward force of the pop-up base 511 and the locking rotating block 58 are colinear at an angle of zero. At this time, the force storage spring 54 is blocked by the pop-up base 511 and cannot rise. It can only be compressed and stored. As the direct-acting mounting block 55 continues to rise, the adjustable pulling shaft 56 contacts the pulling arm 57, and the pulling arm 57 is driven to rise. Since it is hinged, an oblique upward force can be used from the side. The deadlock rotating block 58 can be pulled in line with the force arm, and the deadlock rotating block 58 rotates outward and no longer blocks the pop-up base 511. The compressed force of the storage spring 54 is released, driving the pop-up base 511 to pop up quickly and lift up the tool mounting seat 512 on the top. The tool mounting seat 512 is slidably connected in the oblique oblique groove 521, and during the rising process, it will move toward the inside of the lower mold 1 of the mold, driving the trimming tool 513 to quickly eject inward and obliquely upward, and scrape off the excess clay material bonded to the upper mold 2 of the mold. When the upper mold 2 of the mold moves downward, it will be connected to the direct-acting mounting block 55 again through the upper mold connecting ring 51 and contact the mounting block limit ring 551, pressing it down to restore the entire mechanism.

7. A method for using an automatic mold opening and closing mechanism, characterized in that: Using an automatic mold opening and closing mechanism as described in any one of claims 1 to 6 comprises the following steps: S1. After the clay is formed, the motor (34) is started to drive the outer rotating disk (35), the rotating disk connecting shaft (351) and the toggle rod (36) to rotate. The motor (34) is connected to the active crank (37) at one end and the other end is connected to the outer rotating disk (35) at the other end through the rotating disk connecting shaft (351) extending from the motor (34). The outer rotating disk (35) only rotates, and the motor (34) drives the active cranks (37) on both sides to rotate. The active crank (37) drives the driven crank (38) and the inner moving block (39) connected thereto to move. In the initial state The direct-acting column (391) and the rotating column (392) on the inner moving block (39) are both in the direct-acting groove (32) on the fixed side plate (31). The two active cranks (37) first push the inner moving block (39) upward, which can be regarded as a crank slider mechanism, until the direct-acting column (391) reaches the end of the direct-acting groove (32). At this time, the two active cranks (37) can no longer push the inner moving block (39) upward. At the same time, the rotating column (392) is at the connection between the direct-acting groove (32) and the rotating groove (33). At this time, the two active cranks (37) continue to push the inner moving block (39) upward. The inner moving block (39) is connected to the inner moving block (39) by the bracket mounting arm (310) and the moving block connecting rod (393), so as to ensure the synchronous movement and rotation of the two sides. When the inner moving block (39) rotates, the bracket mounting arm (310) is installed with the upper die connecting arm (311) through the bracket mounting bolt (3101), and the upper die connecting arm (311) is installed with the connecting plug block (312) through the connecting groove (3111), and the connecting plug block (312) is connected to the inner moving block (39) by the bracket mounting arm (310) and the moving block connecting rod (393). The mold opening vibration mechanism (4) is connected to the mold upper mold (2) through the plug-in block connecting bolt (421), and the portion where the connecting plug-in block (312) is connected to the connecting groove (3111) is a semicircular rectangle and cannot rotate, so the upper mold connecting arm (311) always remains parallel to the mold upper mold (2), so that the bracket mounting arm (310) drives the mold upper mold (2) to rotate through the upper mold connecting arm (311) as the inner moving block (39) rotates, thereby realizing the movement process of the mold upper mold (2) first rising and then turning over, thereby leaving the top space vacant, making it easy to tip the mold for cleaning and maintenance; S2. When the motor (34) drives the outer rotating disk (35) to rotate, the toggle rod (36) on the surface of the outer rotating disk (35) will also be driven to rotate. In the initial state, the toggle rod (36) is away from the lower mold toggle groove (313) on the lower mold (1), but the toggle rod (36) will still gradually approach the lower mold toggle groove (313) as the rotation progresses until the direct-acting column (391) reaches the end of the direct-acting groove (32), and the toggle rod (36) contacts the lower mold toggle groove (313). At this time, the toggle rod (36) continues to rotate with the outer rotating disk (35) and presses down the lower die toggle groove (313), driving the lower die toggle groove (313) to slide downward on the path limit ring (314) and compress the rotation return spring (315), thereby driving the mold lower die (1) to flip downward. When the motor (34) is reversed, the toggle rod (36) no longer presses down the lower die toggle groove (313), and the rotation return spring (315) drives the lower die toggle groove (313) and the mold lower die (1) to return to their original position. S3. During the movement of the mold upper mold (2), since the mold upper mold (2) and the connecting plug block (312) are not directly connected, but are installed through the plug block connecting bolts (421), the connecting plug block (312) is installed inside the vibration installation groove (42) and can slide up and down on the plug block connecting bolts (421). Since the height position of the connecting plug block (312) is fixed following the upper mold connecting arm (311) and the inner moving block (39), and the relative position of the connecting plug block (312) and the mold upper mold (2) is not fixed, the mold upper mold (2) can be moved on the upper mold connecting arm (311) and the inner moving block (39). During the lifting movement, the plug block (312) moves up and down in a small range. During the upward movement of the connecting plug block (312), the driven gear (43) connected to the plug block on the outside is meshed with the fixed rack (41) on the fixed side plate (31). The driven gear (43) drives the external driven cam (44) to rotate. The driven cam (44) continuously lifts up and down the driven connection on the upper mold (2), so that the upper mold (2) of the mold vibrates up and down periodically. The plug block vibration spring (422) is distributed between the plug block connection bolt (421) and the vibration installation groove (42), so that the vibration curve is smoother, which facilitates the demoulding of the molded clay. S4, the upper die (2) of the mold is clamped on the direct-acting mounting block (55) through the upper die connecting ring (51) and the extrusion block (552) and can be disconnected. The outer surface of the extrusion block (552) is two inclined planes, and the top inclined plane contacts the upper die connecting ring (51). When the upper die (2) of the mold moves downward, the upper die connecting ring (51) enters from the smaller end of the extrusion block (552), presses the extrusion block (552) into the direct-acting mounting block (55) and compresses the internal extrusion reset spring (553) until it is separated from the top inclined plane of the extrusion block (552). The extrusion reset spring (553) drives the extrusion block (552) to reset. At this time, the bottom of the upper die connecting ring (51) is placed on the top of the mounting block limit ring (551) and the extrusion block (552) is pressed. The upper die (2) of the mold is connected to the direct-acting mounting block (55) through the upper die connecting ring (51). When the upper die (2) of the mold moves upward, it first drives the direct-acting mounting block (55) to move upward together. At this time, the lower die extrusion shell (510) on the lower die (1) of the mold contacts the lower inclined plane on the extrusion block (552). The more the direct-acting mounting block (55) moves upward, the deeper it is pressed into by the lower die extrusion shell (510) until it is completely sunk into the interior. At this time, the upper die connecting ring (51) is no longer restricted by the bottom of the top inclined plane on the extrusion block (552) and falls off from the direct-acting mounting block (55). At this time, the upper die (2) of the mold is not connected to the direct-acting mounting block (55). The direct-acting mounting block (55) is on the lower die (1) of the mold. The lower die mounting groove (52) moves inside and extends outward, so that the extrusion block (552) is linked with the external structure. The moving path of the direct-acting mounting block (55) is limited by the lower die mounting groove (52) and the spring mounting column (53). The direct-acting mounting block (55) will squeeze the top force storage spring (54) during the upward movement. At this time, the pop-up base (511) at the top of the force storage spring (54) is stuck by the top-locking rotating block (58). The top-locking rotating block (58) is perpendicular to the pop-up base (511). The upward force of the pop-up base (511) and the collinear angle of the top-locking rotating block (58) are zero. At this time, the force storage spring (54) is blocked by the pop-up base (511) and cannot rise. It can only be compressed and stored. It continues to move with the direct-acting mounting block (55). The ascending adjustable pulling shaft (56) contacts the pulling arm (57), and the pulling arm (57) is driven to ascend. Since it is hinged, an oblique upward force can be applied from the side. Since it is not in line with the force arm, the top dead rotation block (58) can be pulled. The top dead rotation block (58) rotates outward and no longer blocks the pop-up base (511). The compressed force of the storage spring (54) is released, driving the pop-up base (511) to quickly pop up and lift the top tool mounting seat (512). The tool mounting seat (512) is slidably connected in the oblique oblique groove (521). During the ascending process, it moves toward the inside of the lower mold (1) of the mold, driving the trimming tool (513) to quickly eject obliquely inward and upward, and scrape off the excess clay material bonded to the upper mold (2).When the upper die (2) of the mold moves downward, it will be connected to the direct-acting mounting block (55) again through the upper die connecting ring (51) and contact the mounting block limit ring (551), pressing it downward to restore the entire mechanism.
