DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a fully automatic mold changing method for a small mold, comprising the following steps:

[0037] The first step: the stacking mechanism 1 moves along the track to between two symmetrically arranged pallet warehouses 2, and removes the mold 7 on the pallet warehouse 2. Then the stacking mechanism 1 drives the mold 7 to move along the track to one side of the conveying mechanism 3, and conveys the mold 7 to the conveying mechanism 3 along the X axis;

[0038] Step 2: The mold 7 on the conveying mechanism 3 is transferred along the Y axis to the AGV trolley 5 on one side of the pallet warehouse 2 by the depalletizing mechanism 4;

[0039] Step 3: The mold 7 is moved to one side of the injection molding machine 6 by the AGV trolley 5, and the AGV trolley 5 is docked with the injection molding machine 6. The mold 7 in the injection molding machine 6 is first moved out, and then the mold 7 on the AGV trolley 5 that needs to be transported to the injection molding machine 6 is transported to the injection molding machine 6;

[0040] Step 4: The mold 7 removed from the injection molding machine 6 is driven by the AGV trolley 5 to be transferred to one side of the stacking mechanism 1 , and the stacking mechanism 1 transfers the mold 7 to the pallet library 2 .

[0041] Specifically, a track and a gap for the stacking mechanism 1 to pass through are provided between the two pallet warehouses 2. The walking mechanism 11 of the stacking mechanism 1 drives the mold shifting mechanism 12 to move along the track in the Y-axis direction to move the mold 7 in the pallet warehouse 2 out, and moves along the track to one side of the conveying mechanism 3. The first lifting drive mechanism 13 of the stacking mechanism 1 drives the mold shifting mechanism 12 to move up and down, so that the mold shifting mechanism 12 corresponds to the conveying mechanism 3, and the mold shifting mechanism 12 transfers the mold 7 to the tooling 32 of the conveying mechanism 3. Then the second lifting drive mechanism 43 of the destacking mechanism 4 drives the clamping mechanism 42 to move downward, and the clamping mechanism 42 clamps the mold 7 on the conveying mechanism 3. The second lifting drive mechanism 43 drives the clamping mechanism 42 to move the mold 7 upward. The horizontal drive mechanism 44 drives the second lifting drive mechanism 43 and the clamping mechanism 42 to move along the Y-axis direction to above the mold changing station 533 of the AGV trolley 5. The second lifting drive mechanism 43 drives the clamping mechanism 42 to move the mold 7 downward, and places the mold 7 on the mold changing station 533. Then the AGV trolley 5 drives the mold 7 to move to one side of the injection molding machine 6. The AGV trolley 5 first docks the vacant mold changing station 533 with the injection molding machine 6. The push-pull mechanism 100 on the mold changing station 533 pulls out the mold 7 that has been injected in the injection molding machine 6 and moves it to the mold changing station 533. Then the direct module drives the support plate 532 to drive the two mold changing stations 533 to move, so that the mold changing station 533 where the new mold 7 is placed docks with the injection molding machine 6. The push-pull mechanism 100 of the mold changing station 533 pushes the mold 7 to be transferred to the injection molding machine 6, completing the mold changing operation of the mold 7. Finally, the AGV trolley 5 drives the mold 7 that has been injected to move to one side of the stacking mechanism 1, and the stacking mechanism 1 transfers the mold 7 on the AGV trolley 5 to the pallet warehouse 2 for storage. Among them, the pallet warehouse 2 can not only store the mold 7, but also store the mold 7, materials, tooling 32, etc. in a mixed manner. The materials and tooling 32 can be moved out to the conveying mechanism 3 through the stacking mechanism 1 and moved to the next mechanism along with the conveying mechanism 3 .

[0042] The above-mentioned fully automatic mold changing method for small molds realizes the automatic outbound, conveying, mold changing and warehousing operations of the small molds 7 through the cooperation of the pallet warehouse 2, the stacking mechanism 1, the conveying mechanism 3, the AGV trolley 5 and the injection molding machine 6.

The mold shifting mechanism 12 is installed on the walking mechanism 11, and the driving end of the first lifting drive mechanism 13 is connected to the mold shifting mechanism 12. The mold shifting mechanism 12 includes a stand 121 and a telescopic fork 122. The telescopic fork 122 is installed on the stand 121, and the telescopic fork 122 is used to move the mold 7 in the pallet warehouse 2. The walking mechanism 11 drives the mold shifting mechanism 12 to move horizontally along the track in the Y-axis direction. The telescopic fork 122 of the mold shifting mechanism 12 extends into the bottom of the pallet rack 21 to move the mold 7 on the pallet rack 21 out. The walking mechanism 11 drives the telescopic fork 122 to drive the mold 7 to move to one side of the conveying mechanism 3. The first lifting and driving mechanism 13 drives the platform 121 to drive the telescopic fork 122 to lift and lower, so that the telescopic fork 122 corresponds to the conveying mechanism 3, and the telescopic fork 122 transfers the mold 7 to the conveying mechanism 3. When the AGV trolley 5 drives the mold 7 that has been injected to one side, the first lifting and driving mechanism 13 drives the platform 121 to drive the telescopic fork 122 to lift and lower, so that the telescopic fork 122 docks with the mold changing station 533 where the mold 7 is placed, and the mold 7 on the mold changing station 533 is removed and transferred to the pallet rack 21 of the pallet warehouse 2 for storage. This setting facilitates the operation of taking the mold 7 out of the warehouse and into the warehouse, and improves the efficiency of taking the mold 7 in and out of the warehouse.

[0044] like Figure 5As shown, in one embodiment, the stacking mechanism 4 of the fully automatic mold changing method for small molds includes a support frame 41, and the top of the support frame 41 is provided with a clamping mechanism 42 for clamping the mold 7 on the conveying mechanism 3, a second lifting drive mechanism 43 for driving the clamping mechanism 42 to move up and down, and a horizontal drive mechanism 44 for driving the clamping mechanism 42 to move horizontally along the support frame 41.

The bottom of the support frame 41 is connected to the ground, and the top of the support frame 41 is higher than the conveying mechanism 3 and the AGV trolley 5. The clamping mechanism 42, the first lifting drive mechanism 13, and the horizontal drive mechanism 44 are all installed on the top of the support frame 41. The second lifting drive mechanism 43 drives the fixed plate 421 to drive the two clamping plates 423 to move downward, the clamping drive assembly 422 drives the two clamping plates 423 to clamp the mold 7 on the conveying mechanism 3, the second lifting drive mechanism 43 drives the clamping plates 423 to drive the mold 7 to move upward, the horizontal drive mechanism 44 drives the second lifting drive mechanism 43 to drive the mold 7 to slide horizontally along the top of the support frame 41, so that the mold 7 is located directly above the mold changing station 533 of the AGV trolley 5, and the second lifting drive mechanism 43 drives the mold 7 to move downward, placing the mold 7 on the mold changing station 533 of the AGV trolley 5. This setting not only improves the transfer efficiency of the mold 7, but also greatly saves the occupied space of the overall equipment.

The two cylinders 001 drive the two clamping plates 423 to move in opposite directions, so that the two clamping plates 423 clamp the mold 7 at the same time or release the mold 7 at the same time. The magnetic templates 002 are provided on the opposite surfaces of the two clamping plates 423. When the two clamping plates 423 clamp the mold 7, the two magnetic templates 002 adsorb the mold 7. This setting not only improves the clamping efficiency, but also strengthens the clamping force on the mold 7.
