[0004] Referring to the above technical solution, when the tray moves down to place the mold, the shelf and the mold are susceptible to a large impact force when the mold contacts the shelf, and the large impact force will affect the life of the shelf and the mold. Summary of the invention

[0005] In order to improve the technical problem that when the mold contacts the shelf, the shelf and the mold are subjected to a large impact force, which affects the life of the shelf and the mold, the present application provides a mold conveying mechanism and a conveying method.

[0006] In the first aspect, the present application provides a mold conveying device, including a placement rack, a horizontal plate that can move in the front-to-back direction is provided on the placement rack, a vertical plate that can move in the left-to-right direction is provided on the horizontal plate, a mounting plate that can move in the up-and-down direction is provided on the vertical plate, a pair of fork plates are provided on the mounting plate, and also includes: a placement plate and a buffer mechanism; the placement plate is hingedly provided on the placement rack and is located on one side of the vertical plate, a plurality of support plates extending in the left-to-right direction are fixedly connected to the placement plate, the support plates gradually increase in height from the side close to the vertical plate to the outside of the placement rack, and the distance between adjacent support plates is greater than the width of the fork plate; the buffer mechanism is provided on the placement rack, and the buffer mechanism is used to reduce the vibration of the mold when it is placed; the buffer mechanism includes a pressure plate, the pressure plate is provided below the side of the placement plate away from the vertical plate, a shock absorber is provided below the pressure plate, and a reset spring is provided between the shock absorber and the pressure plate.

[0007] By adopting the above technical solution, when the mold needs to be transported, the fork plate will be affected by the gravity of the mold and the end will tilt downward. When the mold is transported from the fork plate to the placement rack, the horizontal plate moves and drives the vertical plate, the support plate and the fork plate to move in the front-to-back direction. The fork plate is aligned with the support plate in the front-to-back direction. Then the support plate moves and drives the fork plate to move in the vertical direction. The height of the fork plate is higher than the position of the hinge between the placement plate and the placement rack. Then the vertical plate moves and drives the fork plate to move in the left-right direction. The fork plate moves and pushes the placement plate to rotate downward at the end away from the vertical plate. The rotation of the placement plate drives the support plate to rotate synchronously.

[0008] After the vertical plate moves and drives the mold on the fork plate to move to the corresponding area of ​​the placement plate, the support plate moves downward, driving the fork plate and the mold downward. The downward movement of the mold pushes the placement plate and the support plate away from the vertical plate to continue to rotate downward, and the mold gradually falls on the support plate. While the placement plate away from the vertical plate rotates downward, the return spring is compressed under the push of the placement plate, and the shock absorber reduces the vibration.

[0009] In the present application, when the fork plate moves away from the vertical plate and moves downward to place the mold on the support plate, it can push the end of the support plate away from the vertical plate to rotate downward. Through the downward rotation of the support plate, on the one hand, the distance between the support plate and the mold can be gradually reduced, reducing the impact force. On the other hand, the placed mold can be blocked by tilting, reducing the risk of the mold sliding down and falling. While the support plate rotates, the shock absorber can play a buffering role, reducing the impact of the impact force on the placement rack and the mold, which is beneficial to increasing the life of the placement rack and the mold.

[0010] Optionally, limit blocks are provided on both left and right sides below the placement plate, and the upper surfaces of the limit blocks are inclined downward in the direction from the middle to both ends of the placement plate, and the limit blocks are fixedly connected to the placement frame.

[0011] By adopting the above technical solution, the setting of the limit block can not only limit the rotation angle of the placement plate, but also support the support plate when the mold is heavy.

[0012] Optionally, a moving mechanism is provided on the support plate, and the moving mechanism is used to drive the fork plate to move in the front-rear direction.

[0013] By adopting the above technical solution and setting the moving mechanism, the distance between the fork plates can be shortened, thereby facilitating the fork plates to transport molds of different models and sizes.

[0014] Optionally, the moving mechanism includes a synchronous belt arranged in the mounting plate, the synchronous belts are arranged in the same number as the fork plates, and each synchronous belt can drive a fork plate to move horizontally in the front-rear direction.

[0015] By adopting the above technical solution, when the fork plate needs to move, the synchronous belt conveys and drives the fork plate to move, and the movement of the fork plate reduces or increases the distance between the two fork plates, and the structure is simple.

[0016] Optionally, a placement groove is provided on the fork plate, and two rotating rollers are arranged in the placement groove, and the two rotating rollers are distributed up and down. A sliding groove that can be connected to the placement groove is provided on the fork plate, and a sliding rod is slidably connected in the sliding groove. Both rotating rollers are rotatably connected to the sliding rod, and the distance between the top of the rotating roller located at the upper side and the bottom of the rotating roller located at the lower side is greater than the thickness of the fork plate.

[0017] By adopting the above technical solution, when the distance between the fork plates needs to be adjusted, the rotating roller located below is first pressed against the ground or the upper surface of the support plate, the rotating roller located below is pressed upward and pushes the sliding rod and the rotating roller located above to move upward, and the rotating roller located above moves upward and abuts against the mold. By abutting the rotating roller against the mold, the friction between the fork plate and the mold can be reduced, thereby facilitating the movement of the fork plate.

[0018] By setting up two rotating rollers and a sliding rod, when the fork plate does not need to be moved, the rotating roller will not contact the mold, which is beneficial to ensuring that the mold is stably placed on the fork plate. When the fork plate needs to be moved, the rotating roller can abut against the mold, which is beneficial to reducing the friction between the mold and the fork plate, which not only facilitates the movement of the fork plate, but also reduces the risk of damage to the fork plate and the mold due to friction.

[0019] Optionally, wedge-shaped grooves are provided on the support plates located on both sides of the placement plate, and wedge-shaped blocks that can cooperate with the wedge-shaped grooves are fixedly connected to the placement plate.

[0020] By adopting the above technical solution, the setting of the wedge groove and the wedge block allows the distance between the support plates to be adjusted, thereby conveniently increasing the number of support plates supporting the mold, which is beneficial to improving the supporting effect on the mold.

[0021] Optionally, the height of the fork plate is lower than the height of the support plate.

[0022] By adopting the above technical solution, the setting of the fork plate height can facilitate placing the mold on the support plate and can facilitate moving the fork plate out of the gap between the support plates.

[0023] In a second aspect, the present application provides a mold conveying method, which is applied to a mold conveying device described in the first aspect, and the conveying method includes:

[0025] S2, conveying, the movement of the vertical plate drives the fork plate to move in the left and right directions. The movement of the fork plate first pushes the placement plate and the support plate away from the end of the vertical plate to rotate downward around the hinge. Then the mold on the fork plate is in the range of the placement plate, the mounting plate moves downward and drives the fork plate and the mold to move downward. The fork plate moves downward and continues to push the placement plate and the support plate away from the end of the vertical plate to rotate downward around the hinge. The mold gradually falls on the support plate. At the same time, the return spring is compressed during the downward rotation of the end of the support plate away from the vertical plate, and the shock absorber reduces the vibration.

[0026] By adopting the above technical method, the distance between the support plate and the mold can be gradually reduced during the transportation of the mold, thereby reducing the impact force.

[0027] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0028] 1. In the present application, when the fork plate moves away from the vertical plate and moves downward to place the mold on the support plate, it can push the end of the support plate away from the vertical plate to rotate downward. The downward rotation of the support plate can gradually reduce the distance between the support plate and the mold and reduce the impact force. On the other hand, the placed mold can be blocked by tilting, reducing the risk of the mold sliding down and falling. While the support plate rotates, the shock absorber can play a buffering role, reducing the impact of the impact force on the placement rack and the mold, which is beneficial to increasing the life of the placement rack and the mold.

[0029] 2. Through the setting of two rotating rollers and sliding rods, when the fork plate does not need to move, the rotating roller will not contact the mold, which is beneficial to ensure the stability of the mold placed on the fork plate.

The first linear actuator can drive the horizontal plate 11 to move in the front-back direction; the vertical plate 12 is arranged in the middle of the placement frame 1 and is slidably connected to the horizontal plate 11. A second linear actuator is installed on the horizontal plate 11. The second linear actuator is used to drive the vertical plate 12 to move in the left-right direction; the mounting plate 2 is slidably connected to the vertical plate 12. A third linear actuator is arranged on the vertical plate 12. The third linear actuator is used to drive the mounting plate 2 to move up and down in the vertical direction. The above is the prior art. A fork plate 21 is installed on the mounting plate 2. The fork plate 21 is used to place the mold. The gap between the support plates 31 is greater than the width of the fork plate 21, and the height of the support plate 31 is greater than the thickness of the fork plate 21.

[0041] During transportation, the first linear drive first drives the horizontal plate 11, the vertical plate 12, the mounting plate 2 and the fork plate 21 to move, and the fork plate 21 moves in the front-to-back direction to the corresponding position of the placement plate 3. Then the third linear drive drives the mounting plate 2 and the fork plate 21 to move, and the fork plate 21 moves in height to the corresponding position of the placement plate 3. Then the second linear drive drives the vertical plate 12, the mounting plate 2 and the fork plate 21 to move, and the vertical plate 12 moves in the left-right direction to the corresponding position of the placement plate 3.

[0042] Reference Figure 2 and Figure 3, the buffer mechanism 4 includes a pressure plate 41, a return spring 43 and a shock absorber 42. The pressure plate 41 is arranged below the side of the placement plate 3 away from the vertical plate 12, the shock absorber 42 is arranged below the pressure plate 41, and the return spring 43 is arranged between the shock absorber 42 and the pressure plate 41. Among them, the shock absorber 42 includes a shell 421, a connecting rod 422 and a piston 423.

[0043] When the mold is transported, the placement plate 3 rotates to push the pressure plate 41 downward, the return spring 43 is compressed, and the shock absorber 42 performs shock absorption. The setting of the buffer mechanism 4 can reduce the impact on the placement rack 1 and the mold, which is beneficial to increase the life of the placement rack 1 and the mold.

[0044] Reference Figure 2 and Figure 3 A mold conveying device further includes a limit block 5. A plurality of limit blocks 5 are provided, and the plurality of limit blocks 5 are distributed on the left and right sides below the placement plate 3, and the limit blocks 5 are fixedly connected to the placement frame 1, and the upper surfaces of the limit blocks 5 are inclined downward in the direction from the middle of the placement plate 3 to both ends.

[0045] By setting the limit block 5, the rotation angle of the placement plate 3 can be limited, and the support plate 31 can be supported when the mold is heavy.

[0046] Reference Figure 4 A mold conveying device further includes a moving mechanism 6. The moving mechanism 6 is disposed on the support plate 31, and is used to drive the fork plate 21 to move in the front-rear direction. The moving mechanism 6 includes a synchronous belt 61. The synchronous belt 61 is provided with the same number of corresponding fork plates 21, and each synchronous belt 61 can drive one fork plate 21 to move horizontally in the front-rear direction.

[0047] When the fork plate 21 needs to move, the synchronous belt 61 conveys and drives the fork plate 21 to move. The movement of the fork plate 21 reduces or increases the distance between the two fork plates 21, and the structure is simple.

[0048] By setting the moving mechanism 6, the distance between the fork plates 21 can be shortened, so that the fork plates 21 can be conveniently used to transport molds of different models and sizes.

[0049] Reference Figure 5A mold conveying device further includes a placement groove 211, a rotating roller 7, a sliding groove 212 and a sliding rod 71. The placement groove 211 is provided on the fork plate 21, the axis of the rotating roller 7 extends in the horizontal direction and is provided with two, the two rotating rollers 7 are distributed in the placement groove 211 up and down, the sliding groove 212 is provided on the fork plate 21 corresponding to the placement groove 211 and can be communicated with the placement groove 211, the sliding rod 71 is slidably connected in the sliding groove 212, the two rotating rollers 7 are both rotatably connected to the sliding rod 71, and the distance between the top of the rotating roller 7 located at the top and the bottom of the rotating roller 7 located at the bottom is greater than the thickness of the fork plate 21.

[0050] When the distance between the fork plates 21 needs to be adjusted, first the rotating roller 7 located below is pressed against the ground or the upper surface of the support plate 31, the rotating roller 7 located below is pressed upward and pushes the sliding rod 71 and the rotating roller 7 located above to move upward, and the rotating roller 7 located above moves upward and abuts against the mold. The abutment between the rotating roller 7 and the mold facilitates the movement of the fork plate 21.

[0051] By setting the two rotating rollers 7 and the sliding rod 71, when the fork plate 21 does not need to move, the rotating roller 7 will not contact the mold, which is beneficial to ensure the stability of the mold placed on the fork plate 21. When the fork plate 21 needs to move, the rotating roller 7 can abut against the mold, which is beneficial to reduce the friction between the mold and the fork plate 21, which not only facilitates the movement of the fork plate 21, but also reduces the risk of damage to the fork plate 21 and the mold due to friction.

[0052] Reference Figure 4 A mold conveying device also includes a wedge-shaped groove and a wedge-shaped block 32. The wedge-shaped groove is opened on the support plate 31 located on both sides of the placement plate 3, and the wedge-shaped block 32 is fixedly connected to the placement plate 3 and can cooperate with the wedge-shaped groove.

[0053] By providing the wedge-shaped grooves and the wedge-shaped blocks 32 , the distance between the support plates 31 can be adjusted, thereby conveniently increasing the number of support plates 31 supporting the mold, which is beneficial to improving the supporting effect on the mold.

[0054] In the present application, when the fork plate 21 moves away from the vertical plate 12 and moves downward to place the mold on the support plate 31, it can push the end of the support plate 31 away from the vertical plate 12 to rotate downward. Through the downward rotation of the support plate 31, on the one hand, the distance between the support plate 31 and the mold can be gradually reduced to reduce the impact force. On the other hand, the placed mold can be blocked by tilting, reducing the risk of the mold sliding down and falling. While the support plate 31 rotates, the shock absorber 42 can play a buffering role, reducing the impact of the placement rack 1 and the mold, which is beneficial to increasing the life of the placement rack 1 and the mold.

[0055] The implementation principle of a mold conveying device in the embodiment of the present application is:

[0056] When the mold needs to be transported to the placement rack 1, the fork plate 21 will be affected by the gravity of the mold and the end will tilt downward. At this time, the horizontal plate 11 will move first and drive the vertical plate 12, the support plate 31 and the fork plate 21 to move in the front and rear directions. The fork plate 21 is aligned with the support plate 31 in the front and rear directions. Then the support plate 31 moves and drives the fork plate 21 to move in the vertical direction. The height of the fork plate 21 is higher than the position of the hinge between the placement plate 3 and the placement rack 1. After that, the vertical plate 12 moves and drives the fork plate 21 to move in the left and right directions. The fork plate 21 moves and pushes the placement plate 3 to rotate downward at the end away from the vertical plate 12. The rotation of the placement plate 3 drives the support plate 31 to rotate synchronously.

[0057] After the vertical plate 12 moves and drives the mold on the fork plate 21 to move to the corresponding area of ​​the placement plate 3, the support plate 31 moves downward, driving the fork plate 21 and the mold downward. The downward movement of the mold pushes the placement plate 3 and the support plate 31 away from the end of the vertical plate 12 to continue to rotate downward, and the mold gradually falls on the support plate 31. While the placement plate 3 rotates downward at the end away from the vertical plate 12, the return spring 43 is compressed under the push of the placement plate 3, and the shock absorber 42 damps the vibration. After the mold is placed, the vertical plate 12 moves and drives the fork plate 21 to move in the direction away from the placement plate 3, and the fork plate 21 moves out from the gap between the support plates 31.

[0058] In a second aspect, the present application provides a mold conveying method, which is applied to a mold conveying device described in the first aspect, and the conveying method includes:

[0059] S1, alignment, the horizontal plate 11 moves to drive the fork plate 21 to align with the placement plate 3 in the front-to-back direction, the installation plate 2 moves to drive the fork plate 21 to move in the height direction, and the fork plate 21 moves to a position higher than the hinge between the placement plate 3 and the placement rack 1;

[0060] S2, conveying, the vertical plate 12 moves and drives the fork plate 21 to move in the left and right directions. The movement of the fork plate 21 first pushes the placement plate 3 and the support plate 31 to rotate downward around the hinge at one end away from the vertical plate 12, and then the mold on the fork plate 21 is in the range of the placement plate 3, the mounting plate 2 moves down and drives the fork plate 21 and the mold to move down, the fork plate 21 moves downward and continues to push the placement plate 3 and the support plate 31 to rotate downward around the hinge at one end away from the vertical plate 12, and the mold gradually falls on the support plate 31. At the same time, the support plate 31 rotates downward at the end away from the vertical plate 12, so that the return spring 43 is compressed, and the shock absorber 42 damps the vibration.

[0061] Through the above technical method, the distance between the support plate 31 and the mold can be gradually reduced during the transportation of the mold, thereby reducing the impact force.

[0062] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
