The inner wall of the fixed plate 601 contacts with a connecting block 602, and a corresponding through groove is provided on the inner wall of the fixed plate 601. The through groove enables the positioning block 603 mentioned later to move horizontally. The bottom end of the connecting block 602 is fixedly connected with the positioning block 603, and the outer wall of the connecting block 602 is fixedly connected with a telescopic rod 604. The connecting block 602 and its telescopic rod 604 are both provided with two groups. The inner wall of the positioning block 603 is elastically connected with a wedge block 608 through a connecting spring 607, and the inclined surface of the wedge block 608 faces downward. The inner wall of the mold 5 is slidably connected with a movable plate 605, and the movable plate 605 is provided with two groups and is both L-shaped. The outer wall of the movable plate 605 is fixedly connected with a top plate 606, and the finished aluminum alloy piece is ejected through the top plate 606.

[0035] Reference Figure 1-Figure 3The bottom end of the top plate 606 is fixedly connected with a guide rod 609, and the outer wall of the guide rod 609 is slidably connected to the central inner wall of the mold 5. The guide rod 609 plays a guiding role. One end of the connecting spring 607 is fixedly connected to the outer wall of the wedge block 608, and the other end of the connecting spring 607 is fixedly connected to the inner wall of the positioning block 603. The outer wall of the wedge block 608 is slidably connected to the inner wall of the positioning block 603. The wedge block 608 has a reset function through the elasticity of the connecting spring 607. The outer wall of the movable plate 605 contacts the outer wall of the wedge block 608, and the outer wall of the movable plate 605 contacts the inclined surface of the wedge block 608. The cross section of the pressing plate 4 is adapted to the inner groove of the mold 5. The two are adapted to achieve the purpose of aluminum alloy preforming. The outer wall of the telescopic rod 604 is fixedly connected to the outer wall of the hydraulic rod 3, and the movement of the hydraulic rod 3 can drive the telescopic rod 604 to move.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The supporting mechanism 7 includes a supporting block 701, the outer wall of the supporting block 701 is fixedly connected to the outer wall of the base 1, and the supporting block 701 is provided with two groups. The inner wall of the supporting block 701 is elastically connected to the plug-in column 703 through a limit spring 704, and the purpose of limiting or releasing the limit is achieved by moving the plug-in column 703. The outer wall of the base 1 is fixedly connected to a fixing block 702, and the outer wall of the fixing block 702 is rotatably connected to a supporting plate 705. A wave groove is provided at the bottom end of the supporting plate 705, and the friction between the supporting plate and the ground can be increased through the wave groove.

[0037] Reference Figure 1 , Figure 4 and Figure 5 One end of the limit spring 704 is fixedly connected to the inner wall of the support block 701, and the other end of the limit spring 704 is fixedly connected to the outer wall of the plug-in column 703. The outer wall of the plug-in column 703 is slidably connected to the inner wall of the support block 701. The elasticity of the limit spring 704 makes the plug-in column 703 have the reset and limiting functions. The outer wall of the support plate 705 is provided with a plug-in hole, and the outer wall of the plug-in column 703 is plugged into the inner wall of the plug-in hole. There are two groups of plug-in holes, one group is used for limiting in the supporting state, and the other group is used for limiting in the storage state of the support plate 705.

[0038] Working principle: When relevant personnel need to perform aluminum alloy pre-forming operations, first start the hydraulic rod 3 so that the hydraulic rod 3 drives the pressure plate 4 to move downward. When the pressure plate 4 moves downward, it will drive the two sets of telescopic rods 604 to move together, thereby causing the connecting block 602 to slide on the inner wall of the fixed plate 601. Since the inner wall of the fixed plate 601 is provided with a through groove, the two ends of the two sets of telescopic rods 604 will first move toward the middle. When the pressure plate 4 moves to a certain extent, the bottom end inclined surface of the wedge block 608 contacts the top of the movable plate 605, so that the wedge block 608 moves toward the inner wall of the positioning block 603, and then the pressure plate 4 can be completely moved to the inner wall of the mold 5. When the pressure plate 4 is completely moved to the inner wall of the mold 5, the top of the movable plate 605 does not contact the bottom end of the wedge block 608. Due to the elasticity of the connecting spring 607, the wedge block 608 is reset, thereby completing the aluminum alloy pre-forming operation.

[0039] When the aluminum alloy preforming operation is completed, the pressure plate 4 is moved upward by the hydraulic rod 3. At this time, the two groups of positioning blocks 603 will move toward the middle, so that the top of the wedge block 608 will contact the top bottom surface of the movable plate 605. At this time, the top plate 606 can be moved upward to take out the finished product, and then the finished product is manually removed, and then the pressure plate 4 is continued to be moved upward. When it moves to a certain position, the two groups of positioning blocks 603 will move to both ends until the wedge block 608 is no longer in contact with the movable plate 605. At this time, due to the self-gravity of the top plate 606 and its movable plate 605, the top plate 606 is reset, thereby facilitating the next demolding operation. The overall operation process is simple and convenient.

[0040] When the base 1 moves to the specified position, the plug-in column 703 is moved outward to contact the limit of the plug-in column 703 and the support plate 705, and then the support plate 705 can be rotated so that the bottom end of the support plate 705 contacts the ground. The support plate 705 increases the contact area between the entire device and the ground, thereby making the device more stable and effectively preventing the device from slipping or shaking during the forming process.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
