Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses axle sleeve die casting installation mould. Referring to fig. 1 and 2, the mounting die comprises a frame 1, the frame 1 is integrally frame-shaped, an upper die 2 is mounted on the inner wall of the top of the frame 1, a lower die 3 is mounted on the inner wall of the bottom of the frame 1, a mounting plate 30 is mounted on a bearing surface of the lower die 3, and the upper die 2 corresponds to the mounting plate 30.

A plurality of cylinders 4 are vertically installed on one side, close to the rack 1, of the upper die 2, wherein the end of a piston rod of each cylinder 4 is connected with the top of the rack 1, an installation column 31 is arranged at the middle position of the installation plate 30, the installation column 31 is matched with the inner wall of the installation shaft 5, the installation shaft 5 can be sleeved on the installation column 31 in a sliding mode along the vertical direction, and in addition, a limiting groove which is embedded with the outer wall of the installation shaft 5 is formed in the position, corresponding to the installation column 31, of the upper die 2.

When the staff assembles installation axle 5 and bearing 51, installation axle 5 vertically overlaps and establishes on erection column 31 for bearing 51 is corresponding with the top of installation axle 5, starts cylinder 4, and cylinder 4 presses down bearing 51 along vertical direction with last mould 2 together, makes the top of installation axle 5 arrange in bearing 51, and the top gomphosis mutually with spacing recess. The setting of spacing recess can be under the condition that does not harm bearing 51, and the flaw such as deckle edge of excision installation axle 5 edge not only can increase the pleasing to the eye degree of installation axle 5, also can reduce because of the unnecessary trouble that the deckle edge produced.

In order to limit the deviation of the moving direction of the upper die 2, the guide posts 32 are vertically arranged on the periphery of the mounting plate 30, round corners are arranged at the end parts, close to the upper die 2, of the guide posts 32, guide holes 320 which are embedded with the guide posts 32 are formed in the corresponding positions of the upper die 2, the round corners can reduce the friction force between the round corners and the edges of the guide holes 320, and the guide posts 32 can rapidly enter the guide holes 320.

In addition, a plurality of oil grooves 321 are annularly arranged on the outer side of the guide column 32, the oil grooves 321 can contain a small amount of engine oil, and the engine oil can reduce the friction force between the guide column 32 and the guide hole 320, so that the abrasion caused by long-term friction between the guide column 32 and the upper die 2 is reduced, and the service life of the upper die 2 and the guide column 32 is prolonged.

The adjacent position of guide post 32 is provided with cushion column 33, and cushion column 33 is rectangular distribution on lower mould 3, and the tip that cushion column 33 is close to last mould 2 sets up spring 331, and spring 331 stretches out and draws back along vertical direction, has seted up the position and the corresponding cushion hole 3310 of cushion column 33 on last mould 2, and cushion hole 3310 and spring 331 gomphosis mutually. When the upper die 2 presses the bearing 51 downwards, the spring 331 can reduce the impact force of the upper die 2, and reduce the damage to the bearing 51 caused by the overlarge impact force of the upper die 2.

In addition, an adjusting member 34 is detachably mounted between the two buffer posts 33 through a mounting member, in this embodiment, the mounting member is a mounting block 341 fixedly sleeved on the adjusting member 34 near the end of the lower die 3, a screw 342 is inserted into the mounting block 341 through a thread, and the end of the screw 342 far from the mounting block 341 extends into the mounting plate 30. The upper die 2 is driven by the cylinder 4 to vertically press downwards until the upper die is in close contact with the top of the adjusting piece 34 and cannot be pressed continuously, at the moment, the adjusting piece 34 can reach the height for adjusting the downward pressing of the upper die 2, and therefore the mounting shafts 5 with different heights can be assembled by replacing the adjusting pieces 34 with different heights.

Because the lower die 3 is installed on the frame 1, in order to facilitate the replacement of the installation shaft 5 by the worker, the inner wall of the bottom of the frame 1 is provided with a chute 10 and a limiting groove 11, the extension direction of the chute 10 is consistent with the opening direction of the frame 1, the lower die 3 is connected with the chute 10 in a sliding way, the side wall of the periphery of the lower die 3 is detachably provided with a limiting block 35, the limiting block 35 can be matched with the limiting groove 11, wherein, in the embodiment, the detachable installation method of the limiting block 35 can be that a screw horizontal thread penetrates through the limiting block 35 and extends into the lower die 3,

when the limiting block 35 is detached from the lower mold 3, the lower mold 3 can slide freely on the sliding groove 10, and when the limiting block 35 is fixed on the side wall of the lower mold 3 and is mutually embedded with the limiting groove 11, the limiting block 35 can limit the lower mold 3 to slide on the sliding groove 10 in the limiting groove 11, and the part of the lower mold 3, which is in contact with the sliding groove 10, can limit the limiting block 35 to slide in the limiting groove 11, so that the lower mold 3 can be fixed on the rack 1.
