It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] See also Figures 1 to 7 , an embodiment of the present invention provides a forging device for forging a rotor bracket, the forging device for forging a rotor bracket comprises a base 1 and a lower mold shell 2 arranged above the base 1;

[0041] A mounting shell seat 3 is also fixed between the base 1 and the lower mold shell 2, and the mold cavity inside the lower mold shell 2 has openings at both upper and lower ends. A bottom plate 4 is also provided inside the lower mold shell 2 to close the lower end opening, and the upper end of the bottom plate 4 has a protrusion for qualitatively casting raw materials, and also includes:

[0042] The first ejection unit 7 is installed inside the mounting housing 3. The first ejection unit 7 is composed of a moving drive mechanism 71 and a rotating drive mechanism 72, and the rotating drive mechanism 72 is fixed to the lower end of the bottom plate 4;

[0044] The moving driving mechanism 71 drives the rotating driving mechanism 72 and the bottom plate 4 installed on the rotating driving mechanism 72 to move in the vertical direction, and the rotating driving mechanism 72 drives the bottom plate 4 to rotate in a circle with the axis as the center, and the movement and rotation of the bottom plate 4 are performed synchronously.

[0045] It should be noted that: the device is a mold used to produce the rotor bracket, and the rotor bracket is processed by casting;

[0046] It should also be noted that: in this type of mold, the mold cavity inside the lower mold shell 2 has openings at both the upper and lower ends, and a bottom plate 4 with adjustable position is arranged inside the mold cavity, and the bottom plate 4 is used to close the lower end opening of the mold cavity, thereby forming a completed trough body, and the upper end of the bottom plate 4 has a protrusion for qualitative processing, so that after the metal material is introduced, the rotor bracket can be formed;

[0047] It should also be noted that a first ejection unit 7 is arranged inside the mounting housing 3, and the first ejection unit 7 is composed of a moving drive mechanism 71 and a rotating drive mechanism 72. The moving drive mechanism 71 can drive the bottom plate 4 to move in the vertical direction, so that the bottom plate 4 can move upward inside the mold cavity, and during the upward movement, the formed rotor bracket will be driven to move upward until the rotor bracket is ejected from the mold shell;

[0048] The rotation drive mechanism 72 is arranged between the mobile drive mechanism 71 and the bottom plate 4. The mobile drive mechanism 71 drives the rotation drive mechanism 72, and uses the rotation drive mechanism 72 to drive the bottom plate 4 to move.

[0051] A plurality of through holes are provided at the upper end of the bottom plate 4 and at positions staggered from the protrusions, and the side wall of the bottom plate 4 is in an arc shape matching the inclined surface.

At the same time, the contact area between the side wall of the base plate 4 and the retaining ring 5 is an inclined surface, and a sealing gasket 6 is also provided, thereby further improving the sealing of the mold cavity.

[0053] In the embodiments of the present invention, please refer to Figures 3 to 6 , the mobile driving mechanism 71 comprises:

[0054] A mounting frame 711 is bolted to the inside of the mounting housing 3, and a driving motor 712 is also mounted on the mounting frame 711;

[0055] The bidirectional screw rod 713 is rotatably mounted on the mounting frame 711, and one end of the bidirectional screw rod is axially connected to the output end of the driving motor 712. The bidirectional screw rod 713 is also transmission-connected to two symmetrically arranged transmission seats 714, and drives the two transmission seats 714 to move in opposite directions or in opposite directions. The two transmission seats 714 are both rotationally connected to support arms 715, and the two support arms 715 are arranged in an inverted V shape.

[0056] A fixing ring 716 is rotatably connected to the other ends of the two support arms 715. A first bearing 717 is also disposed inside the fixing ring 716 and fixed to the outer ring of the first bearing 717.

[0057] At the same time, the upper end of the mounting frame 711 has a positioning slide rail 718, and the lower end of the transmission seat 714 has a slide groove, and the positioning slide rail 718 is embedded and slides inside the slide groove;

[0058] The rotation driving mechanism 72 includes:

[0059] The mounting tube 721 is coaxially fixed to the lower end of the bottom plate 4. The inner wall of the mounting tube 721 is also provided with a plurality of annularly distributed, equidistantly arranged and arc-shaped positioning grooves 722. One end of the positioning groove 722 is close to the upper end of the mounting tube 721, and the other end is close to the lower end of the mounting tube 721.

[0060] The positioning cylinder 723 is coaxially arranged inside the mounting cylinder 721 and is rotatably connected thereto. A mounting ring plate 724 is welded to the lower end of the positioning cylinder 723 and is bolted to the inside of the mounting housing 3 through the mounting ring plate 724. The outer wall of the positioning cylinder 723 is also welded with a limit pin 725 corresponding to the position and number of the positioning slot 722, and the limit pin 725 is embedded in and slides inside the positioning slot 722.

A limiting pin 725 is arranged on the outer wall of the positioning cylinder 723. The limiting pin 725 is embedded in and slides inside the positioning groove 722. Therefore, during the upward movement of the installation cylinder 721, the limiting effect of the limiting pin 725 can cause the installation cylinder 721 to rotate. The movement and rotation of the bottom plate 4 can drive the workpiece to move together, so that the workpiece can extend outside the mold cavity.

[0065] It should also be noted that the mounting ring plate 724 at the lower end of the positioning tube 723 is bolted to the inside of the mounting housing 3, so it has sufficient stability and serves as a mounting structure of the mounting tube 721 to ensure the stability of the mounting tube 721.

[0068] The mounting plate 83 is disposed above the output end of the hydraulic cylinder 81 and is also fixed to the outer ring of the second bearing 82. A plurality of ejector rods 84 are vertically welded to the upper end of the mounting plate 83;

[0069] The top rod 84 passes through the bottom plate 4 along the through hole, and the top end of the top rod 84 can be flush with the upper end of the bottom plate 4 or extend to above the bottom plate 4 .

[0070] It should be noted that: in the second ejection unit 8, the hydraulic cylinder 81 can directly drive the mounting plate 83 to move, so that the ejector rod 84 at the upper end of the mounting plate 83 can pass through the through hole on the bottom plate 4 and extend to the top of the bottom plate 4. In this process, the workpiece on the bottom plate 4 can be ejected to realize demoulding of the workpiece;

[0071] It should also be noted that a second bearing 82 is provided between the output end of the hydraulic cylinder 81 and the mounting plate 83 , so that the bottom plate 4 will not affect the hydraulic cylinder 81 during rotation, and the hydraulic cylinder 81 can also drive the mounting plate 83 to move.
