[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 10As shown, a die-casting mold for aluminum alloy forming includes a base plate 1, a column 2 fixedly connected to the upper surface of the base plate 1, a lower mold 3 fixedly connected to the upper surface of the column 2, an upper mold 4 fitted to the upper surface of the lower mold 3, a movable plate 5 fitted to the inner wall of the lower mold 3, a sliding hole 6 opened at the bottom of the lower mold 3, a connecting column 7 fitted to the inner wall of the sliding hole 6, the upper surface of the connecting column 7 fixedly connected to the bottom of the movable plate 5, a horizontal plate 8 fixedly connected to the bottom of the connecting column 7, a first strip ring 9 fixedly connected to the bottom of the horizontal plate 8, the inner wall of the first strip ring 9 fitted to the surface of the column 2, and a spring 10 fixedly connected to the bottom of the first strip ring 9. There is a second strip ring 11, the inner wall of the second strip ring 11 is in contact with the surface of the column 2, the bottom of the second strip ring 11 is fixedly connected to a hollow column 12, the inner wall of the hollow column 12 is fixedly connected to a cylinder 13, the upper surface of the base plate 1 is fixedly connected to an adjusting bracket 14, the surface of the adjusting bracket 14 is fixedly connected to a slider 15, the bottom of the slider 15 is in contact with the upper surface of the base plate 1, the left and right sides of the slider 15 are fixedly connected to a third strip ring 16, the inner wall of the third strip ring 16 is in contact with the surface of the cylinder 13, the upper surface of the horizontal plate 8 is fixedly connected to a pressing column 17, the upper surface of the pressing column 17 is in contact with a top plate 18, the bottom of the top plate 18 is fixedly connected to the upper surface of the upper mold 4.

[0032] The axis of spring 10 coincides with the axis of column 2. The elastic force of spring 10 is greater than the sum of the weight of horizontal plate 8, first strip ring 9 and pressing column 17. Guide cylinders 19 are fixedly connected to both sides of the lower mold 3. The inner wall of guide cylinder 19 is in contact with the surface of pressing column 17. The angle between the third strip ring 16 and the base plate 1 is 45°. The length of the third strip ring 16 is greater than the diameter of cylinder 13.

[0033] The adjusting bracket 14 includes a first U-shaped plate 141, a bearing 142, a threaded column 143, a rotating block 144, and a threaded cylinder 145. The bottom of the first U-shaped plate 141 is fixedly connected to the upper surface of the base plate 1. The inner wall of the first U-shaped plate 141 is fixedly connected to the outer ring of the bearing 142. The inner ring of the bearing 142 is fixedly connected to the surface of the threaded column 143. The front of the threaded column 143 is fixedly connected to the back of the rotating block 144. The surface of the threaded column 143 is threadedly connected to the inner wall of the threaded cylinder 145. The surface of the threaded cylinder 145 is fixedly connected to the inner wall of the slider 15.

[0034] It should be noted that the movable plate 5 has ventilation grooves on its side. When the movable plate 5 moves up and down in the lower mold 3, the ventilation grooves ensure that the air pressure on the upper and lower parts of the movable plate 5 is equal. The movable plate 5 is located in the mold cavity of the lower mold 3. When the upper mold 4 and the lower mold 3 are closed, the cooperation of the pressing column 17 and the top plate 18 allows the bottom surface of the movable plate 5 to make close contact with the inner wall of the lower mold 3. When the upper mold 4 and the lower mold 3 are separated, the pushing force of the spring 10 on the first strip ring 9 allows the movable plate 5 to generate an upward pushing force on the workpiece in the lower mold 3 and push the workpiece out of the lower mold 3. The cooperation of the first strip ring 9 and the column 2 ensures that the horizontal plate 8 can only move up and down. The cooperation of the second strip ring 11 and the column 2 ensures that the horizontal plate 8 can only move up and down. The engagement of column 2 allows the hollow column 12 to move only up and down. When the user rotates the rotating block 144, the rotating block 144 causes the threaded column 143 to rotate, and the engagement of the threaded column 143 and the threaded cylinder 145 causes the slider 15 to move forward or backward. When the slider 15 moves forward, the engagement of the third strip ring 16 and the cylinder 13 causes the second strip ring 11 to move downward, and reduces the pushing force of the spring 10 on the first strip ring 9 during demolding. When the slider 15 moves backward, the engagement of the third strip ring 16 and the cylinder 13 causes the second strip ring 11 to move upward, and increases the pushing force of the spring 10 on the first strip ring 9 during demolding. The guide cylinder 19 allows the pressing column 17 to move only up and down.

[0035] like Figures 1 to 12 As shown, a second U-shaped plate 20 is fixedly connected to the front of the lower mold 3, an electronic tension gauge 21 is fixedly connected to the front of the second U-shaped plate 20, a fourth strip ring 22 is fixedly connected to the measuring end of the electronic tension gauge 21, an L-shaped plate 23 is fitted to the inner wall of the second U-shaped plate 20 and the front of the lower mold 3, the bottom of the L-shaped plate 23 is fixedly connected to the upper surface of the horizontal plate 8, a threaded hole 24 is opened inside the L-shaped plate 23, a bolt 25 is threadedly connected to the inner wall of the threaded hole 24, and the surface of the bolt 25 is fitted to the inner wall of the fourth strip ring 22.

[0036] It should be noted that after the upper mold 4 and the lower mold 3 are closed, the threaded hole 24 is aligned with the fourth strip ring 22 by the cooperation of the pressing column 17 and the top plate 18. Then, the bolt 25 is inserted into the fourth strip ring 22 and screwed into the threaded hole 24. Through the cooperation of the bolt 25 and the threaded hole 24, the L-shaped plate 23 can be connected with the fourth strip ring 22. After the upper mold 4 and the lower mold 3 are separated, through the cooperation of the bolt 25, the threaded hole 24, the L-shaped plate 23 and the fourth strip ring 22, the electronic tension gauge 21 can directly measure the pushing force of the movable plate 5 on the workpiece in the lower mold 3. At this time, the user can accurately adjust the pushing force of the movable plate 5 on the workpiece in the lower mold 3 to the specified size by observing the value on the electronic tension gauge 21. The L-shaped plate 23 can only move up and down by the second U-shaped plate 20.

[0037] The working principle of this utility model is as follows: First, the upper mold 4 and the lower mold 3 are joined together, and the bottom surface of the movable plate 5 is brought into close contact with the inner wall of the lower mold 3 by the cooperation of the pressing column 17 and the top plate 18. Then, the raw material is injected into the mold cavity of the lower mold 3, and the air pressure in the mold cavity of the lower mold 3 is increased. After the raw material is cooled and formed in the lower mold 3, the upper mold 4 and the lower mold 3 are separated. Then, the spring 10 pushes the first strip ring 9, so that the movable plate 5 generates an upward pushing force on the workpiece in the lower mold 3 and pushes the workpiece out of the lower mold 3.

[0038] When it is necessary to adjust the pushing force of the movable plate 5 on the workpiece during demolding, first put the upper mold 4 and the lower mold 3 together, and align the threaded hole 24 with the fourth strip ring 22 by the cooperation of the pressing column 17 and the top plate 18. Then, insert the bolt 25 into the fourth strip ring 22 and screw it into the threaded hole 24. Through the cooperation of the bolt 25 and the threaded hole 24, the L-shaped plate 23 can be connected with the fourth strip ring 22. When the upper mold 4 and the lower mold 3 are separated, through the cooperation of the bolt 25, the threaded hole 24, the L-shaped plate 23 and the fourth strip ring 22, the electronic tension gauge 21 can directly measure the pushing force of the movable plate 5 on the workpiece in the lower mold 3.

[0039] Then, by rotating the rotating block 144, the slider 15 moves forward or backward under the cooperation of the threaded column 143 and the threaded cylinder 145. When the slider 15 moves forward, the second strip ring 11 moves downward through the cooperation of the third strip ring 16 and the cylinder 13, and the pushing force of the spring 10 on the first strip ring 9 during demolding is reduced. When the slider 15 moves backward, the second strip ring 11 moves upward through the cooperation of the third strip ring 16 and the cylinder 13, and the pushing force of the spring 10 on the first strip ring 9 during demolding is increased. When the value on the electronic tension gauge 21 reaches the specified value, it indicates that the pushing force of the movable plate 5 on the workpiece in the lower mold 3 has reached the specified size. Then, the upper mold 4 and the lower mold 3 are put together, and the bolt 25 is unscrewed from the threaded hole 24.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
