[0037] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0038] like Figures 1-5 As shown, this embodiment relates to an automatically adjustable mold shell flipping device, including: a left support frame 1, a right support frame 2, a flipping mechanism 3, a horizontal rotary reducer 4, a vertical rotary reducer 5, a connecting assembly 6, a clamping mechanism 7, and a limiting frame 8.

[0039] The connecting assembly 6 includes the connection structure between the various parts. The clamping mechanism 7 is connected to the horizontal rotary reducer 4 via the connecting flange 61, and the horizontal rotary reducer 4 is mounted on the tilting mechanism 3 via the mounting plate 62.

[0040] The mold shell 9 consists of a mold shell fixture 91 and a mold shell body 92. In particular, since it adopts a clamping hook, as long as the mold shell fixture 91 is consistent, the flipping device can adapt to mold shells of different sizes. The maximum external size of the mold shell cannot exceed the distance between the inner sides of the two support frames of the flipping frame 31.

[0041] Specifically, the clamping mechanism's hook design can be adjusted according to actual needs to adapt to different mold shell shapes. The clamping mechanism 7 includes a piston, connecting rod, cylinder, and hook. The mold shell is placed on the hook of the clamping mechanism, and the internal piston movement retracts the hook via the connecting rod, clamping the mold shell. The piston movement is driven by compressed air, with the air pressure set between 0.5-0.7 MPa to ensure clamping stability. After the mold shell is clamped, the clamping mechanism rotates coaxially with the rotary reducer 4.

[0042] The turnover mechanism 3 comprises a turnover frame 31, a bearing seat 32, a rotating shaft 33, a shaft end baffle 34 and a fixed plate 35. The left side of the turnover frame 31 is connected with the left support frame 1 through the rotating shaft 33, the outer end of the rotating shaft 33 is arranged on the left side of the support frame 1 through the bearing seat 32, and the inner end is connected to the inner side of the left side of the turnover frame 31 through the fixed plate 35. The shaft end baffle 34 is arranged on the end of the rotating shaft 33 exposed from the bearing seat 32; the right side of the turnover frame 31 is connected with the right support frame 2 through the vertical rotary speed reducer 5.

[0043] The horizontal rotary speed reducer 4 is used to realize the rotation of the mold shell in the horizontal direction. The rotating speed of the rotary speed reducer is set between 1-3 rpm to ensure the stability and accuracy of the turnover. According to the characteristics of the operation process, the iron wire is usually bound after the shell is made. Only 90° turnover of the mold shell is needed, and the turnover frame will touch the limiting frame 8 when it is turned to the position, which can ensure that the turnover frame is located in the appropriate angle through the mechanical hard limiting, and can be fixed after reaching the position, which ensures the operation safety. A kind of automatic control system is designed to adjust the turnover speed of the mold shell according to the needs, and in the whole working process, the mold shell is hung on the grab hook of the clamping mechanism by the transfer device, the movement of the clamping mechanism and the turnover mechanism is controlled by the automatic control system, the mold shell is clamped and controlled, and then the mold shell is horizontally rotated according to the actual situation, and then the mold shell is turned over in space, which ensures the stability of the work. It can effectively solve the technical problems of large mold shell turnover with high labor intensity and low safety, and also solve the technical problems of low work efficiency of manual turnover method and cannot meet the needs of automatic continuous production.

[0044] The above is only a further embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the scope disclosed by the present application, which belongs to the protection scope of the present application.
