Technical Field
[0001] The utility model relates to the technical field of manipulators, in particular to a mold changing manipulator. Background Art
[0002] During the production process of silicone rubber molds, it is necessary to automatically move the silicone rubber molds from one device to another. Conventional manipulators use vertical cylinders to control gripper plates. An upper cylinder controls one gripper plate independently, and a lower cylinder controls another gripper plate independently. The two gripper plates move toward the middle for clamping at the same time, or a pneumatic gripper is used alone. The former has a complicated structure and high production cost, while the latter has insufficient clamping force and cannot clamp the silicone rubber mold tightly. Utility Model Content
[0003] One purpose of the utility model is to provide a mold changing robot, which realizes the clamping of the silicone rubber mold by bringing the upper and lower claw plates closer to the middle through a linkage structure through a group of cylinders in the horizontal direction, with a simplified structure and sufficient clamping force.

[0006] As a preferred technical solution, the transverse movement structure is a clamping cylinder, and the piston end of the clamping cylinder is rotatably connected to the piston rod pin.
[0007] As a preferred technical solution, a finger guide rail is provided at the front end of the gripper fixing seat along the vertical direction, and a finger slider is fixed at the rear end of the gripper connecting plate, and the finger slider slides on the finger guide rail.
[0008] As a preferred technical solution, a finger connecting block is fixed on the gripper connecting plate, and a gripper spacer plate is installed between the gripper connecting plate and the finger connecting block.
[0009] The beneficial effects of the utility model are: providing a mold changing robot, which controls the rotation of the finger connecting plate through the forward and backward movement of the transverse movement structure, and then links the claw connecting plate to move closer to the middle to clamp the mold, with a reasonable and stable structure and strong clamping force.

[0016] The technical solution of the present utility model is further described below with reference to the accompanying drawings and through specific implementation methods. Figures 1 to 3 As shown, in this embodiment, a mold changing robot includes a gripper fixing seat 1, a transverse movement structure, a piston rod pin 2, a finger connecting plate 3 and a gripper connecting plate 4. The transverse movement structure is fixed at the rear end of the gripper fixing seat 1, and the piston rod pin 2 laterally passes through the driving front end of the transverse movement structure. A rod pin movable groove 5 is provided in the middle of the front end of the gripper fixing seat 1 along the horizontal direction. The piston rod pin 2 moves in the rod pin movable groove 5. A gripper plate pin 6 is rotated up and down at the front end of the gripper fixing seat 1. The gripper plate pin 6 passes through the middle of the finger connecting plate 3. A first notch is provided at one end of the finger connecting plate 3. The piston rod pin 2 is clamped in the first notch. A second notch is provided at the other end of the finger connecting plate 3. A joint 7 is provided at the rear end of the gripper connecting plate 4. The joint 7 is clamped in the second notch. The gripper connecting plate 4 slides at the front end of the gripper fixing seat 1 along the vertical direction.
[0017] Specifically, the transverse movement structure is a clamping cylinder 8, and the piston end of the clamping cylinder 8 is rotatably connected to the piston rod pin 2. When the clamping cylinder 8 moves forward, it pushes the piston rod pin 2 to move forward synchronously in the rod pin movable groove 5. Since the upper finger connecting plate 3 can only be fixed on the hand claw fixing seat 1 under the restriction of the hand claw plate pin 6, the piston rod pin 2 moves forward. Under the linkage of the first notch, the finger connecting plate 3 moves forward, driving the second notch to move upward, and the second notch drives the joint 7 to force the upper hand claw connecting plate 4 to move upward. Similarly, due to the action between the lower finger connecting plate 3, piston rod pin 2 and hand claw connecting plate 4, the lower hand claw connecting plate 4 also moves downward to open the clamping structure. When the silicone rubber mold needs to be clamped and moved, the clamping cylinder 8 contracts the piston end, and at the same time controls the upper and lower hand claw connecting plates 4 to move closer to the middle to clamp the silicone rubber mold.
[0018] A finger guide rail 9 is arranged at the front end of the gripper fixing seat 1 along the vertical direction, and a finger slider 10 is fixed to the rear end of the gripper connecting plate 4. The finger slider 10 slides on the finger guide rail 9. When the finger connecting plate 3 rotates a certain angle, the gripper connecting plate 4 can only move in the up and down directions due to the action of the finger slider 10 and the finger guide rail 9.
[0019] A finger connecting block 11 is fixed on the gripper connecting plate 4, and a gripper spacer plate 12 is installed between the gripper connecting plate 4 and the finger connecting block 11. Silicone rubber molding requires high temperature, and the temperature on the silicone rubber mold must be high. Adding the gripper spacer plate 12 increases the service life of the manipulator.
[0020] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
