It should be understood that the specific examples described herein are intended to be illustrative only and are not in any way limiting of the present application. In addition, it should be noted that, for the purpose of clarity, only those structures related to the present application are shown in the drawings and not all structures.

[0044] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0046] In the description of the present embodiment, the terms "upper", "lower", "right", "left", and other orientation or position relationships are based on the orientation or position relationships shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0047] In the prior art, the hoisting device is usually arranged on the front side or the rear side of the core making machine. When the hoisting device is arranged on the front side, the hoisting device includes a monorail crane, and sufficient hoisting space needs to be left. When the hoisting device is arranged on the rear side, the hoisting device includes a monorail crane, a rear roller changing table, a transition roller table and an internal lifting roller table, and the structure is complex, the land occupation area is large, the cost is high, and the mold needs to be transferred by cooperating with a forklift or other transfer tool in both arrangement modes.

[0048] Therefore, as shown in Figures 1-5 The present embodiment provides a core box transfer device for transferring a core box to a moving part 1001 of a core making machine 100. The core box transfer device includes a moving vehicle body 1 and a supporting device. The moving vehicle body 1 includes a mounting plane. The supporting device is arranged on the mounting plane and includes a driving assembly 2 and two groups of supporting mechanisms 3 arranged along the X-axis. The mold frame of the core box has two extension plates 2001 at both ends along the X-axis. The two groups of supporting mechanisms 3 support the two extension plates 2001 respectively. The moving vehicle body 1 can move towards or away from the moving part 1001 to move the core box above or away from the moving part 1001. The driving assembly 2 is configured to drive the supporting mechanisms 3 to move downward or upward along the Z-axis to drive the core box to move along the Z-axis to be inserted into or pulled out of the moving part 1001.

[0049] The movable component 1001 has a first station for automatic loading and unloading and a second station for sand-shooting core making. When loading is required, the movable component 1001 moves to the first station, and the movable vehicle 1 moves to the core box temporary storage area. Two sets of support mechanisms 3 support the extension plates 2001 at both ends of the core box to achieve initial loading of the core box. The movable vehicle 1 moves towards the movable component 1001 to move the core box above the movable component 1001. The drive assembly 2 drives the two sets of support mechanisms 3 to descend along the Z-axis, so that the core box descends vertically and is inserted and fixed onto the movable component 1001. After loading is completed, the support mechanisms 3 continue to... The support mechanism 3 descends a small distance along the Z-axis to disengage from the extension plate 2001 of the core box, thus avoiding interference with the movement of the subsequent moving component 1001. The moving component 1001 carries the core box to the second station. After the core is made, the moving component 1001 carries the core box back to the first station. The drive assembly 2 drives the two sets of support mechanisms 3 to rise along the Z-axis to support the extension plate 2001 again. Then the core box is pulled out of the moving component 1001. The moving vehicle 1 moves away from the moving component 1001 to move the core box above the moving component 1001 and transfer the core box to the next process.

[0050] Compared with existing technologies, the core box transfer equipment provided in this embodiment eliminates the need for permanent steel structures such as crossbeams and forklift aisles. This core box transfer equipment can automate the transfer and loading / unloading of core boxes, replacing the lifting device and forklift systems, reducing production costs, and saving factory space by occupying a small area. This core box transfer equipment can directly carry the core box. The moving vehicle 1 can transfer the core box from the core box temporary storage area to the first workstation and complete the insertion in one pass, eliminating the need for forklift round trips and secondary lifting, resulting in high transfer efficiency.

[0051] It should be noted that the moving part 1001 has a positioning pin, and the core box is positioned and inserted into the positioning pin.

[0052] In one optional embodiment, the mobile vehicle 1 is a regular trolley with rotating wheels, which is manually pushed; in another optional embodiment, the mobile vehicle 1 is an AGV trolley, which can realize automated transfer. The specific structure of the mobile vehicle 1 depends on the actual needs. Any vehicle structure capable of movement and transfer in the prior art can be used as the mobile vehicle 1 in this embodiment, and this embodiment does not limit it.

[0053] It should be noted that the number of supporting devices is not limited; there can be one or more. When there are multiple supporting devices, they are spaced apart along the Y-axis on the moving vehicle body 1, and the multiple supporting devices jointly support the core box. In this embodiment, as... Figure 1 , Figure 4 As shown, the number of supporting devices is one.

[0054] Optionally, such as Figures 1-4As shown, the supporting mechanism 3 comprises a lifting assembly 31 and a bracket 32, the driving assembly 2 can drive the lifting assembly 31 to move along the Z axis; the bracket 32 is arranged at the output end of the lifting assembly 31, and the bracket 32 comprises a supporting piece 321, the supporting piece 321 comprises a supporting portion 3211 and a limiting portion 3212, the limiting portion 3212 is arranged at one side of the supporting portion 3211 along the X axis direction at an included angle, the extension plate 2001 is supported on the supporting portion 3211, and the extension plate 2001 is limited to abut against the limiting portion 3212. The extension plate 2001 of the core box is supported on the supporting portion 3211, the supporting portion 3211 bears the whole weight of the core box, the limiting portion 3212 abuts against the side surface of the extension plate 2001, and the two limiting portions 3212 of the two supporting pieces 321 jointly limit the core box, so that the core box cannot displace along the X axis direction, the position of the core box during the transfer process can be ensured to be stable, the position of the core box placed on the bracket 32 each time can be ensured to be fixed, and it is not necessary to adjust multiple times, and the core box can be correctly inserted into the moving piece 1001 after being moved to the moving piece 1001.

[0055] Optionally, as shown in Figure 3 As shown, the supporting piece 321 further comprises a guide portion 3213, the guide portion 3213 is connected with the top end of the limiting portion 3212 and extends away from the core box along the upward direction of the Z axis, and the guide portion 3213 is used for guiding the core box to be supported on the supporting portion 3211. When the core box is placed downward along the Z axis direction to the supporting portion 3211 or the supporting mechanism 3 supports the core box upward along the Z axis direction to the supporting portion 3211, since the guide portion 3213 has an outward opening structure along the upward direction of the Z axis, the extension plate 2001 will first hit the inclined surface of the guide portion 3213, and then slide to the supporting portion 3211 under the guidance of the inclined surface of the guide portion 3213, and the core box abuts against the limiting portion 3212 on both sides along the X axis. The guide portion 3213 can eliminate the error of the core box along the X axis direction when falling, so that the core box can stably slide to the correct position under the guidance of the guide portion 3213, and the extension plate 2001 first hits the inclined surface of the guide portion 3213 instead of a hard corner when falling and contacting the supporting piece 321, so as to avoid impact noise and damage to the core box caused by placement.

[0056] It should be noted that the supporting portion 3211, the limiting portion 3212 and the guide portion 3213 in the embodiment are integrally formed, and can be formed by forging, casting or the like, which is not limited in the embodiment.

[0057] Optionally, as shown in Figure 1 , Figure 2 and Figure 3As shown, the bracket 32 further comprises a bracket 32 body provided at the output end of the lifting assembly 31, and the supporting member 321 is provided at the top end of the bracket 32 body. A plurality of universal ball bearings 323 are arranged on the side of the bracket 32 body of the two supporting mechanisms 3 facing each other, and the two bracket 32 bodies can respectively roll against the two sides of the moving piece 1001 along the X-axis. The two bracket 32 bodies can limit the position of the moving vehicle body 1 relative to the moving piece 1001 on the X-axis, play a positioning role, ensure that the core box provided on the supporting device is accurately positioned after moving to the moving piece 1001, and cannot be inserted downward to the moving piece 1001 due to the position offset on the X-axis; by arranging the universal ball bearings 323, the bracket 32 body can form rolling contact with the side wall of the moving piece 1001, reduce the frictional resistance between the bracket 32 body and the moving piece 1001, and reduce the wear of the bracket 32 body and the moving piece 1001.

[0058] It should be noted that the supporting member 321 can be provided at the top end of the bracket 32 body by welding, riveting, threaded connection or gluing, and the present embodiment does not limit this.

[0059] Optionally, as shown in Figure 2 , Figure 3 and Figure 4 , the bracket 32 further comprises a mounting plate 324 provided at the output end of the lifting assembly 31, and the number of the bracket 32 body is multiple. The mounting plate 324 is arranged on the mounting plate 324 along the Y-axis. By arranging the mounting plate 324, the plurality of bracket 32 bodies are integrated on the mounting plate 324, and the plurality of bracket 32 bodies support the core box together, so that the supporting performance of the supporting device is better, and the core box can be stably supported on the supporting device and is not easy to overturn. For example, as shown in Figure 4 , the number of the bracket 32 body is two.

[0060] Optionally, the bracket 32 body can be detachably arranged on the mounting plate 324. The number of the bracket 32 body arranged on the mounting plate 324 can be changed at any time according to actual needs, which is simple and fast. When only one bracket 32 body is damaged, the damaged bracket 32 body only needs to be replaced, without the need for overall scrapping, which reduces the maintenance cost and improves the maintenance efficiency.

[0061] Optionally, as shown in Figure 1 , Figure 4As shown, the core box transfer device further comprises a limiting member 4 arranged on the mounting plane, and the limiting member 4 can abut the outer side of the moving member 1001 along the Y-axis direction. By arranging the limiting member 4, the position of the moving vehicle body 1 relative to the moving member 1001 on the Y-axis can be limited, thereby playing a positioning role. When the limiting member 4 abuts the outer side of the moving member 1001 along the Y-axis direction, the moving vehicle body 1 is moved to the position, so that the core box arranged on the supporting device is accurately positioned after being moved to the moving member 1001, and cannot be inserted downward into the moving member 1001 due to the position deviation on the Y-axis. It should be noted that the Y-axis direction is the direction in which the moving vehicle body 1 moves towards or away from the moving member 1001.

[0062] Optionally, as shown in Figure 4 As shown, the side of the bracket 32 and the mounting plane facing each other is provided with a guide member 5, and the guide member 5 is provided with a guide groove 51 extending along the Y-axis. The lifting assembly 31 comprises a first connecting rod 311 and a second connecting rod 312 rotatably connected. The first end of the first connecting rod 311 is connected with the output end of the driving assembly 2, and the second end of the first connecting rod 311 is slidably arranged in one guide groove 51. The first end of the second connecting rod 312 is rotatably connected with the bracket 32, and the second end of the second connecting rod 312 is slidably arranged in the other guide groove 51. The driving assembly 2 is configured to drive the first connecting rod 311 to rotate around the axis of the output end of the driving assembly 2. When the driving assembly 2 drives the first connecting rod 311 to rotate, since the second end of the first connecting rod 311 is slidably arranged in the guide groove 51, the second end of the first connecting rod 311 will move along the Y-axis in the guide groove 51, so that the length of the first connecting rod 311 along the Z-axis changes, thereby driving the bracket 32 to rise or fall along the Z-axis. At the same time, the second connecting rod 312 will rotate under the driving of the first connecting rod 311, and the second end of the second connecting rod 312 will also move along the Y-axis in the guide groove 51, so that the length of the second connecting rod 312 along the Z-axis changes.

[0063] Optionally, as shown in Figure 4 As shown, the second end of the first connecting rod 311 and the second end of the second connecting rod 312 are rotatably provided with a roller 313, and the two rollers 313 are respectively rollingly arranged in the two guide grooves 51, so that the first connecting rod 311 and the second connecting rod 312 respectively produce rolling friction with the guide grooves 51, thereby reducing the wear degree of the first connecting rod 311 and the second connecting rod 312.

[0064] Optionally, as shown in Figure 5As shown, the driving assembly includes a driving member 21 and a transmission rod 23, the fixed end of the driving member 21 is arranged on the mounting plane, and the output end of the driving member 21 is connected with a driving gear 22; the transmission rod 23 is rotatably arranged on the mounting plane, and a driven gear 24 is connected on the transmission rod 23, the driven gear 24 is engaged with the driving gear 22, and the number of teeth of the driving gear 22 is less than that of the driven gear 24, and the first end of the first connecting rod 311 is connected with the transmission rod 23. When the output end of the driving member 21 rotates, the driving gear 22 drives the driven gear 24 to rotate, and then drives the transmission rod 23 to rotate, and then drives the first connecting rod 311 to rotate, and then converts the rotation of the first connecting rod 311 into the numerical lifting movement of the bracket 32; since the number of teeth of the driving gear 22 is less than that of the driven gear 24, the rotation speed can be reduced while the torque is amplified, so that the rotation speed of the first connecting rod 311 is relatively slow, and then the lifting speed of the bracket 32 is relatively slow, which is more stable, and the large torque output ensures that the core box can be stably lifted, and cannot be lifted due to the excessive weight of the core box.

[0065] In an optional embodiment, the number of the driving assemblies 2 is two, and the two driving assemblies 2 drive two groups of the supporting mechanisms 3.

[0066] In the embodiment, the driving assembly 2 is located on one side of the carrying device, and the first connecting rods 311 of the two groups of the supporting mechanisms 3 are connected with the transmission rod 23. That is, one driving assembly 2 can drive the lifting of the two groups of the supporting mechanisms 3 at the same time, so that the structure of the core box carrying device is more compact, the cost is lower, and the two groups of the supporting mechanisms 3 can be lifted synchronously without additional setting, so as to ensure the synchronism of the driving of the core box and prevent the core box from tilting.

[0067] Optionally, the driving member 21 in the embodiment is a speed reduction motor.

[0068] Optionally, as shown in Figure 1 、 Figure 4 The core box carrying device in the embodiment further includes an electric cabinet 6, the electric cabinet 6 is arranged on the mounting plane, the controller, the encoder and the like are integrated in the electric cabinet 6, and the electric cabinet 6 is electrically connected with the driving member 21. By arranging the electric cabinet 6, the wiring distance of the control lines can be reduced, so that the control lines of the core box carrying device are more neat and safe.

For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application.
