[0041] Figures 1 to 7 As shown, a pushing mechanism is installed inside the mold body 1, and a trigger mechanism is installed on each side of the mold body 1;

[0042] The pushing mechanism includes four first springs 8, one end of each of the four first springs 8 is mounted on the inner side of the bottom wall of the mold body 1, and a first push plate 9 is mounted on the other end of each of the four first springs 8.

[0045] When the top plate 6 drives the heating block 7 to move into the inner side of the mold body 1 for extrusion molding, the pressure rod 17 presses a group of clips 14 downward under the external force of the top plate 6, so that a group of clips 14 rotate around the positioning rod 13 under the action of external force, so that the clips 14 no longer position the side plate 12, and the first spring 8 uses its own elastic force to drive the first push plate 9 to move upward, so that the first push plate 9 drives the side plate 12 to move upward through the short column 10 and the support plate 11.

The top of the round shell 22 is connected to one end of the return spring 23, and a rotating block 24 is installed on the inner side of the round shell 22. A trigger rod 25 is installed at the bottom of the rotating block 24, and the trigger rod 25 is located at the bottom of the round shell 22, a short rod 26 is installed on the top of the rotating block 24, a support plate 27 is installed on one side of the short rod 26, and the support plate 27 is located at the top of the mold body 1, a positioning frame 28 is installed on the front of the support plate 27, a semicircular block 29 is sleeved on the outer side of the positioning frame 28, a second push plate 30 is installed on one side of the semicircular block 29, and the second push plate 30 is located on the front of the support plate 27, the back of the second push plate 30 is connected to one end of a fourth spring 31, and the other end of the fourth spring 31 is connected to the support plate 27, and a slide shell 32 is installed on the back of the mold body 1.

[0047] In the embodiment of the present utility model, the driving motor 18 can support the short shell 19 under the support of the mold body 1, and the short shell 19 can provide a movable space for the third spring 20 and the movable block 21. The circular shell 22 can provide a rotation space for the rotating block 24 under the fixed support of the mold body 1. The rotating block 24 can support the trigger rod 25 and the short rod 26 under the support of the circular shell 22, so that the short rod 26 can fix the support plate 27. The positioning frame 28 can support the semicircular block 29 under the fixed support of the support plate 27 to rotate under the action of external force.

The slide shell 32 can guide the formed rare earth magnesium alloy to move under the fixed support of the mold body 1;

[0048] When the formed rare earth magnesium alloy completes the demolding work, the drive motor 18 is controlled to operate, so that the output end of the drive motor 18 drives the movable block 21 to rotate through the short shell 19, so that the movable block 21 drives the trigger rod 25 to rotate. While rotating, the movable block 21 is squeezed by the trigger rod 25 and slowly moves downward, so that the trigger rod 25 can drive the rotating block 24 and the short rod 26 to rotate. The trigger rod 25 drives the second push plate 30 to move through the rotating block 24, the short rod 26, the support plate 27, the positioning frame 28 and the semicircular block 29, so that the second push plate 30 can push the demolded rare earth magnesium alloy block out of the top of the mold body 1, so that the rare earth magnesium alloy block slides downward along the slide shell 32, thereby facilitating the staff to take the rare earth magnesium alloy block.

[0049] When the second push plate 30 pushes the rare earth magnesium alloy block out of the top of the mold body 1, the fourth spring 31 supports the second push plate 30 to reset. At the same time, the movable block 21 is squeezed by the trigger rod 25 to move toward the inside of the short shell 19, so that the movable block 21 is separated from the trigger rod 25, and the return spring 23 uses its own elastic force to drive the support plate 27 to rotate in the opposite direction, so that the support plate 27 drives the second push plate 30 to reset through the positioning frame 28 and the semicircular block 29. At the same time, the movable block 21 is reset under the elastic support of the third spring 20, so as to facilitate the pushing of the next formed rare earth magnesium alloy block.

[0050] Working principle: The staff controls the operation of the extrusion device to heat the heating block 7, so that the downward pressure component of the extrusion device drives the heating block 7 to move downward, and the rare earth magnesium alloy raw material is extruded by moving into the inner side of the mold body 1. When the top plate 6 drives the heating block 7 to move into the inner side of the mold body 1 for extrusion molding, the pressure rod 17 presses a group of buckles 14 downward under the external force of the top plate 6, so that a group of buckles 14 rotate around the positioning rod 13 as the center under the action of external force, so that the buckle 14 no longer positions the side plate 12, so that the first spring 8 uses its own elastic force to drive the first push plate 9 to move upward, so that the first push plate 9 drives the side plate 12 to move upward through the short column 10 and the support sheet 11. At the same time, the first push plate 9 can push the formed rare earth magnesium alloy block upward through the bottom plate 4 under the action of external force to move out of the inner side of the mold body 1, thereby making the rare earth magnesium alloy block After the demoulding is completed, when the formed rare earth magnesium alloy completes the demoulding, the driving motor 18 is controlled to operate so that the output end of the driving motor 18 drives the movable block 21 to rotate through the short shell 19, so that the movable block 21 drives the trigger rod 25 to rotate. While rotating, the movable block 21 is squeezed by the trigger rod 25 and slowly moves downward, so that the trigger rod 25 can drive the rotating block 24 and the short rod 26 to rotate. The trigger rod 25 drives the second push plate 30 to move through the rotating block 24, the short rod 26, the support plate 27, the positioning frame 28 and the semicircular block 29, so that the second push plate 30 can push the demoulded rare earth magnesium alloy block out of the top of the mold body 1, so that the rare earth magnesium alloy block slides downward along the slide shell 32, thereby facilitating the staff to take the rare earth magnesium alloy block. The staff presses the bottom plate 4 downward to reset it and performs the extrusion molding of the next piece of rare earth magnesium alloy.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention.
