When the utility model is working, the jacking device can jack up the hydraulic lifting guide rail, so that the mold is separated from the worktable. When the hydraulic cylinder is working, its piston rod moves to push the mold to move to the mold moving arm, and then the mold can be lifted away quickly. The mold transfer arm can also quickly install and fix the mold on the worktable after changing the mold. Compared with the existing technology, the device is simple in structure and easy to operate, and can be applied to molds of various specifications; compared with traditional manual handling of molds, it greatly shortens the time for changing molds and improves the production efficiency of machine tools; In comparison, the cost is lower.

In order to ensure that the mold can be easily removed, two hydraulic cylinders are arranged in parallel, and the extending ends of the piston rods of the two hydraulic cylinders are respectively connected to two opposite end surfaces of the mold.

As a further improvement of the utility model, suspension rings are respectively connected to the protruding end of the piston rod of the hydraulic cylinder and the mold, and the suspension rings are connected through a shackle assembly. This solution makes the connection between the mold and the hydraulic cylinder more convenient.

In order to facilitate the installation of molds of different specifications, the support includes a cross bar, and the cylinder end of the hydraulic cylinder is movably sleeved on the cross bar. The cylinder body of the hydraulic cylinder can be moved so that it can adapt to molds of more specifications.

In order to improve the supporting strength of the mold-moving arm, a supporting piece is provided on the lower side of the mold-moving arm.

In order to further facilitate the removal of the mold, when the hydraulic lifting guide rail is raised, the guide rail rollers are flush with the mold transfer rollers.

detailed description

As shown in Figure 1-3, it is an automatic and quick mold change mechanism for a press, including a worktable 2, which is installed on the machine body 1, and a hydraulic lifting guide rail 3 is installed on the worktable 2, and the hydraulic lifting guide rail 3 is connected to the fuselage 1 through the jacking device 4, and the guide rail roller 5 is installed on the hydraulic lifting guide rail 3; a detachable mold transfer arm 6 is installed on one side of the worktable 2, and the mold transfer arm 6 is connected to the worktable by bolts 2. On the side, a support 7 is provided on the lower side of the mold transfer arm 6, and the mold transfer roller 8 is installed on the mold transfer arm 6. When the hydraulic lifting guide rail 3 is raised, the guide rail roller 5 and the mold transfer roller 8 are flush; the working table 2. A mold push-pull mechanism is installed on the other side. The mold push-pull mechanism includes a bracket 9 and a hydraulic cylinder 10. The bracket 9 is fixed to the workbench. The cylinder body of the hydraulic cylinder 10 is supported on the bracket 9. Dies 14 are connected.

Two hydraulic cylinders 10 are arranged in parallel, and the extending ends of the piston rods 11 of the two hydraulic cylinders are respectively connected to two opposite end surfaces of the mold 14 . Specifically, the extension end of the piston rod 11 of the hydraulic cylinder and the mold 14 are respectively connected with suspension rings 12 , and the suspension rings 12 are connected through a shackle assembly 13 .

The bracket 9 includes a cross bar 901 on which the end of the cylinder body of the hydraulic cylinder 10 is movably sleeved. The body of the hydraulic cylinder 10 can move on the cross bar 901 to adapt to the change of the width of the mold 14 .

The mold push-pull mechanism composed of the bracket 9 and the hydraulic cylinder 10 is used to realize the movement of the mold 14 in and out of the working area of the machine tool, which not only greatly shortens the time for mold replacement, improves production efficiency, but also ensures the safety of operators.

When replacing the mold, first loosen the mold clamping device, and then control the hydraulic oil to enter the jacking device 4 through the solenoid valve, so that the hydraulic lifting guide rail 3 rises and jacks up the mold 14, and the guide rail roller 5 is higher than the working table 2 The surface is flush with the mold-moving roller 8. At this moment, the hydraulic oil is controlled by a solenoid valve to enter the hydraulic cylinder 10, so that the piston rod 11 of the hydraulic cylinder moves forward and pushes the mold 14 to move onto the mold-moving arm 6.
