DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, a bottom mold stacking storage device includes a conveyor line 10, a stacking mechanism, a static frame 40 and a horizontal pushing mechanism 50, which constitute the basic structure of the utility model.

[0027] An activity space is provided in the middle of the conveyor line 10. In the utility model, the conveyor line 10 is a chain conveyor line 10. The chain is provided with two groups and is arranged at intervals so that an activity space is formed between the two chains. A workpiece grabbing station 11 and a bottom mold stacking station 12 are provided on the conveyor line 10. The workpiece grabbing station 11 is arranged on the side adjacent to the feeding end of the conveyor line 10. The workpiece 70 is a neodymium iron boron magnetic block located in the bottom mold 80. The neodymium iron boron magnetic block in the bottom mold 80 is taken away by a grabbing mechanism 90. The grabbing mechanism 90 is not an innovation of the utility model and is not described in detail in the utility model. A retractable first stop mechanism 1 is provided at the position of the conveyor line 10 corresponding to the workpiece grabbing station 11. 3. The first stop mechanism 13 includes a first stop rod and a first driving member that drives the first stop rod to vertically rise and fall. The first driving member is preferably a cylinder. The bottom mold 80 is stopped at the workpiece grasping station 11 by the first stop mechanism 13. When the workpiece 70 is grasped, the first driving member drives the first stop rod to retract. At this time, the bottom mold 80 continues to run under the action of the conveyor line 10. The conveyor line 10 is provided with a third stop mechanism 14 at the position corresponding to the bottom mold stacking station 12. In the utility model, the third stop mechanism 14 is a stop rod, which is used to stop the bottom mold 80 at the bottom mold stacking station 12 through the third stop mechanism 14. At this time, the bottom mold 80 can be stacked by the ejection assembly 30.

[0028] The stacking mechanism includes a stacking rack 20 and a lifting assembly 30. The stacking rack 20 is fixedly arranged at the bottom mold stacking station 12 of the conveyor line 10. The outer peripheries of both sides of the stacking rack 20 are respectively connected with connecting blocks 21. The upper ends of the connecting blocks 21 are rotatably connected with movable supporting blocks 22 through pin shafts. The stacking rack 20 is provided with a channel opening 23 for the movable supporting block 22 to partially extend into the inner end of the stacking rack 20. The movable supporting block 22 can be rotated and switched between a release position and a support position, wherein the support position is a position where the movable supporting block 22 abuts against the lower end surface of the channel opening 23, and the release position is a position where the movable supporting block 22 is rotated to not support the bottom mold 80. The lifting assembly 30 is arranged at the lower end of the corresponding stacking rack 20, and a bottom plate 31 is provided at its output end. The lifting assembly 30 is used to drive the bottom plate 31 to rise and fall and drive the movable supporting block 22 to rotate and switch between the release position and the support position.

[0029] The stationary rack 40 is provided with a stationary table for stationary bottom molds 80. The stationary rack 40 is fixedly arranged at the tail end of the conveyor line 10 for transferring the stacked bottom molds 80. Furthermore, the stationary rack 40 is provided with a cooling fan 41 for cooling the bottom molds 80 located on the stationary table. The stationary table can stack multiple rows of stacked bottom molds 80.

[0030] The pushing mechanism 50 is used to push the bottom mold 80 stacked on the stacking shelf 20 onto the static table. Specifically, the pushing mechanism 50 includes a fixed frame, a third driving member 51 arranged on the fixed frame, and a pushing plate 52 arranged at the output end of the third driving member 51. Furthermore, the L-shaped plate of the pushing plate 52, when it is necessary to push the bottom mold 80 onto the static table, the third stop mechanism 14 retracts to the lower end, so that the bottom mold 80 can be smoothly pushed onto the static table.

[0031] When the movable support block 22 is in the supporting position, the movable support block 22 abuts against the lower end surface of the passage opening 23, and at this time the movable support block 22 can support the bottom mold 80; the ejecting assembly 30 drives the bottom plate 31 and the bottom mold 80 located on the bottom plate 31 to move upward, and drives the movable support block 22 to rotate upward to the release position, and at this time the bottom plate 31 supports the stacked bottom mold 80, the movable support block 22 rotates downward to the supporting position, the ejecting assembly 30 drives the base to move downward, and the stacked bottom mold 80 is supported by the movable support block 22.

[0032] A limiting structure 24 is disposed on the top of the stacking rack 20 , and the limiting structure 24 limits the height at which the bottom mold 80 is pushed up. In the present invention, the limiting structure 24 is a limiting bending portion of the stacking rack 20 that is bent inwardly.

[0033] Two groups of connecting blocks 21 and movable supporting blocks 22 rotatably connected to the connecting blocks 21 are respectively provided on both sides of the stacking shelf 20. Channel openings 23 are respectively provided at positions of the stacking shelf 20 corresponding to the movable supporting blocks 22. This arrangement can provide better support.

[0034] The conveyor line 10 is provided with a retractable second stop mechanism 15 upstream of the workpiece grasping station 11. The second stop mechanism 15 includes a second stop rod and a second driving member for driving the second stop rod to extend and retract laterally. The second stop mechanism 15 is used to stop the bottom mold 80 located upstream of the workpiece grasping station 11 to prevent it from interfering with the bottom mold 80 that is grasping the workpiece 70 at the workpiece grasping station 11.

[0035] The stationary table is flush with or slightly lower than the lower end surface of the lowest bottom mold 80. Through this arrangement, the bottom mold 80 stacked on the movable support block 22 can be smoothly pushed onto the stationary table.

[0036] A roller line 60 is provided between the static frame 40 and the tail end of the conveyor line 10, and the stacked bottom molds 80 are transferred to the static table through the roller line 60. That is to say, the bottom mold 80 located at the bottom mold stacking station 12 is first transferred to the roller line 60 through the push mechanism 50, and then the power of the roller line 60 is used to transfer the stacked bottom molds 80 to the static table.

[0037] In summary, the utility model has the following beneficial effects:

[0038] The bottom mold stacking and storage device of the utility model can automatically stack and recycle the bottom mold 80, which not only solves the safety problem during manual operation, but also greatly improves the recycling efficiency. Specifically, the bottom mold 80 is first transferred from the workpiece grabbing station 11 to the bottom mold stacking station 12 through the conveyor line 10, and the bottom mold 80 located at the bottom mold stacking station 12 is pushed up by the lifting assembly 30, and the movable support blocks 22 on both sides are pushed open to support the bottom mold 80 stacked on the movable support blocks 22. At this time, the movable support blocks 22 are rotated down to the supporting position under the action of gravity, and the lifting assembly 30 moves down. The stacked bottom molds 80 are supported by the movable support blocks 22. When the bottom molds 80 are stacked to a set height, the stacked bottom molds 80 are pushed onto the static table together by the push mechanism 50. After the bottom molds 80 are cooled on the static table for a certain period of time, they are manually moved.

[0039] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
