Detailed Description
As shown in the attached drawings, the utility model comprises a mould fixing bottom plate 1, a supporting seat 2, an oil cylinder mounting plate 3, an oil cylinder 4, a loose core fixing plate 5, a loose core 6, an air cylinder support 7 and an air cylinder 8, wherein the supporting seat 2 is fixedly connected on the mould fixing bottom plate 1, two ends of the oil cylinder mounting plate 3 are respectively movably mounted on the supporting seat 2 through bearings 10, two ends of the oil cylinder mounting plate 3 are respectively provided with a limiting post 11, the supporting seat 2 is provided with a limiting post avoiding hole, the limiting post 11 is provided with a locking handle 12 matched with the supporting seat 2 for use, the loose core 6 is fixedly connected on the loose core fixing plate 5, the loose core fixing plate 5 is movably mounted on the oil cylinder mounting plate 3 through a group of guide posts, the oil cylinder 4 is fixedly connected on the oil cylinder mounting plate 3 and drives the loose core 6 to move back and forth on the oil, and a piston rod of the air cylinder 8 is hinged with the hinged support through a pin shaft.
The limiting column avoiding hole on the supporting seat 2 is a long circular arc-shaped hole.
The locking handle 12 is a cam locking lever, and one end of the cam locking lever is hinged on the limiting column 11 through a pin shaft.
The oil cylinder mounting plate 3 and the loose core 6 are respectively provided with a water cooling integrated block 15.
The die fixing bottom plate 1 is provided with a core-pulling fixing plate limiting seat 16, and the core-pulling fixing plate limiting seat 16 is provided with a wear-resistant strip.
The working mode and principle are as follows: the oil cylinder 4 is used for controlling the core pulling 6 to stretch in the die, the air cylinder 8 pushes the oil cylinder mounting plate 3 to rotate, the core pulling 6 on the oil cylinder mounting plate 3 is rotated to a certain angle, then the core pulling 6 is locked through the locking handles 12 at the two ends, after the core pulling die cavity is fixed, the core pulling die cavity part coating is sprayed additionally, then the locking handles 12 are loosened, the air cylinder 8 resets, and the core pulling 6 is rotated to restore the production state.
The limiting column avoiding hole in the supporting seat 2 is a long circular arc-shaped hole, the circle center positions of the arc-shaped hole and the bearing 10 are the same, and the limiting column 11 moves in the long circular arc-shaped hole by taking the bearing 10 as the circle center during rotation.
