[0029] like Figure 1-6 As shown, the embodiment of the present invention provides a double-station alternating die-casting mold, including: an installation box 1, a movable seat 5 and a unloading mechanism 2, a No. 1 slide rail 6 is fixedly installed on both sides of the upper end of the installation box 1, and the lower end of the movable seat 5 is slidably connected to the upper ends of the two groups of No. 1 slide rails 6 respectively, and two groups of vertical plates 7 are provided at the bottom of the inner wall of the installation box 1, and the upper ends of the two groups of vertical plates 7 are fixedly installed with No. 2 slide rails 10, and a movable bracket 3 is provided inside the installation box 1, and two groups of sliders 11 are fixedly installed near the lower end of the movable bracket 3, and the two groups of sliders 11 are slidably connected to the two groups of No. 2 slide rails 10 respectively, and the two groups of unloading mechanisms 2 are respectively located at the upper ends of the movable bracket 3 and the movable seat 5, and a conveyor belt structure 4 for driving the movable bracket 3 and the movable seat 5 to do reciprocating motion is installed inside the installation box 1, so that the movable bracket 3 can pass smoothly under the movable seat 5 and restore its initial height after further movement, thereby facilitating alternating die-casting.

[0030] The unloading mechanism 2 includes a template base 21 and a cylinder 24. A circular hole 29 is opened inside the template base 21. The lower end of the template base 21 is rotatably connected to two groups of connecting parts 23. One side of the two groups of connecting parts 23 is fixedly connected to the telescopic rod 22. One side of the template base 21 is fixedly connected to a rotating part 28. The lower end of the template base 21 is provided with a fixed frame 26. Both sides of the inner wall of the fixed frame 26 are provided with a rotating seat 27. The rotating part 28 is rotatably connected to the upper end protrusion of the fixed frame 26. The two groups of rotating seats 27 are rotatably connected to the two groups of telescopic rods 22 respectively. The lower end of the template base 21 is connected to the cylinder 24. The outer wall of the mold base 21 is fixed, and a limiting pad 25 is provided inside the mold base 21. The lower end of the limiting pad 25 is fixedly connected to the telescopic end of the cylinder 24. The telescopic end of the cylinder 24 is located inside the circular hole 29. By starting the telescopic rod 22, the telescopic rod 22 extends to drive one end of the mold base 21 to rotate along the rotating member 28 as the axis, thereby tilting the mold base 21, making it convenient for the die-cast workpiece to slide down along the inclined surface. At this time, by starting the cylinder 24 again, the telescopic end of the cylinder 24 extends through the circular hole 29, thereby driving the limiting pad 25 to push the part out of the mold base 21, thereby successfully completing the demoulding operation.

[0031] like Figure 1-6 As shown, the lower end of one group of fixed frames 26 is fixedly connected to the upper end of the mobile bracket 3, and the lower end of the other group of fixed frames 26 is fixedly connected to the upper end of the mobile seat 5. The upper end of the conveyor belt structure 4 is fixedly connected with a transmission member 12, and the upper end of the transmission member 12 is fixedly installed with the lower end of the mobile seat 5. The lower end of the conveyor belt structure 4 is fixedly connected to one side of the movable plate. Pulleys 9 are fixedly installed on both sides of the lower end of the mobile bracket 3. Slide grooves 8 are provided inside the two groups of vertical plates 7. The two groups of pulleys 9 are slidably connected to the two groups of slide grooves 8 respectively. The width of the mobile bracket 3 is smaller than that of the mobile seat 5. It can pass directly under the mobile seat 5 and start the rotation of the conveyor belt structure 4, thereby driving the transmission member 12 and the mobile seat 5 in the direction close to the mobile bracket 3. When the lifting box 1 is lifted up, the lifting plate 5 will move up and down, and the lifting plate 5 will move up and down, and the lifting plate 5 will move up and down, and the lifting plate 5 will move down ...

[0032] The technical solution provided by the present invention is that when performing alternating conversion between double stations, the conveyor belt structure 4 is started to rotate, thereby driving the transmission member 12 and the moving seat 5 to move in the direction close to the moving bracket 3, and the moving seat 5 slides smoothly along the No. 1 slide rail 6 to support the moving seat 5 and drive a group of unloading mechanisms 2 above to move. At the same time, the conveyor belt structure 4 also drives the moving bracket 3 to move in the direction close to the moving bracket 5. When the moving bracket 3 reaches the middle position of the installation box 1, the moving seat 5 also slides to the middle position of the installation box 1 through the No. 1 slide rail 6. At this time, because the pulley 9 slides along the slide groove 8, it first moves to the middle V-shaped part of the slide groove 8 when it reaches the middle V-shaped part of the slide groove 8. It moves downward and then upward. Because the width of the movable bracket 3 is smaller than the width of the movable seat 5, the movable bracket 3 can smoothly pass under the movable seat 5 while moving downward. After further movement, it returns to its initial height, which is convenient for alternating die-casting. At this time, the movable seat 5 moves to the other end of the mounting box 1. By starting the telescopic rod 22, the telescopic rod 22 extends to drive one end of the template seat 21 to rotate along the axis of the rotating member 28, thereby tilting the template seat 21, which facilitates the die-cast workpiece to slide down along the inclined surface. At this time, by starting the cylinder 24, the telescopic end of the cylinder 24 extends through the circular hole 29, thereby driving the limit pad 25 to push the part out of the template seat 21, thereby successfully completing the demoulding operation.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0034] The above is only 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 of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
