[0007] Furthermore, the top of the special-shaped profile mold is higher than the top of the machine body in the initial state, and the special-shaped profile mold is located directly below the die roller. When the die roller moves downward, it will contact the special-shaped profile mold and then drive the special-shaped profile mold to move downward.

[0008] Furthermore, the end of the elastic spring away from the top of the square groove initially contacts the bottom of the special-shaped profile mold, and the special-shaped profile mold moves downward to squeeze the elastic spring so that the elastic spring is gradually tightened.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with an elastic material taking mechanism, so that when the die pressing roller moves downward, it will first contact with the special-shaped profile mold and drive the special-shaped profile mold to move downward, and then the clamping column will be clamped into the front end clamping groove of the special-shaped profile mold to fix the special-shaped profile mold. At this time, when the die pressing roller moves downward again, it will cooperate with the special-shaped profile mold to press the copper alloy inside it. After the pressing is completed, when the die pressing roller moves upward to restore, pulling the pull rod will make the special-shaped profile mold automatically bounce upward. The vibration generated when the special-shaped profile mold bounces upward makes the copper alloy inside it loose, which is convenient for the subsequent removal of the copper alloy after the pressing.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model is a copper alloy special-shaped profile extrusion die, including a machine body 1 and a special-shaped profile die 3. A control panel 2 is arranged at the front end of the machine body 1. A long slot 4 is opened on the top of the machine body 1. A vertical rod 7 is slidably connected inside the long slot 4. A motor 5 is arranged at the bottom of the long slot 4. The motor 5 is electrically connected to the control panel 2 through a wire. The motor 5 is fixedly connected to a threaded rod 6 through its output shaft. The vertical rod 7 is threadedly connected to the threaded rod 6. A cross bar 8 is fixedly connected to the side of the vertical rod 7. A die roller 9 is arranged at the bottom of the cross bar 8. An elastic material taking mechanism 10 is arranged inside the machine body 1. The elastic material taking mechanism 10 includes a square slot 101 and a card slot 105. The square slot 101 is opened on the machine body 1. At the top of the body 1, a slide groove 102 is opened on the inner wall of the square groove 101, and a slider 103 is slidably connected inside the slide groove 102. The end of the slider 103 away from the slide groove 102 is fixedly connected to the special-shaped profile mold 3, and an elastic spring 104 is fixedly connected to the bottom of the square groove 101. A clamping groove 105 is opened in the special-shaped profile mold 3. A groove 106 is opened on the inner wall of the front end of the square groove 101, and a compression spring 107 is fixedly connected to the inner wall of the groove 106. A sliding plate 108 is slidably connected to the inside of the groove 106 through the compression spring 107. A clamping column 109 is fixedly connected to one side of the sliding plate 108, and a pull rod 1010 is fixedly connected to the other side of the sliding plate 108.

[0025] The top of the profile mold 3 is higher than the top of the machine body 1 in the initial state, and the profile mold 3 is located directly below the die roller 9. When the die roller 9 moves downward, it will contact the profile mold 3 and then drive the profile mold 3 to move downward.

[0026] The end of the elastic spring 104 away from the top of the square groove 101 initially contacts the bottom of the profile mold 3 . The downward movement of the profile mold 3 will squeeze the elastic spring 104 and gradually tighten the elastic spring 104 .

[0027] The elastic force of the elastic spring 104 is greater than the gravity of the special-shaped profile mold 3 and the friction between the slider 103 and the slide groove 102. The elastic force of the elastic spring 104 rebounding after being tightened can drive the special-shaped profile mold 3 to bounce upward.

[0028] In the initial state, the end of the clamping column 109 away from the sliding plate 108 is in conflict with the front end of the special-shaped profile mold 3, and the compression spring 107 is in a taut state in the initial state. At the beginning, the clamping column 109 is in conflict with the front end of the special-shaped profile mold 3, so that the compression spring 107 cannot rebound and drive the sliding plate 108 to move.

[0029] The size of the opening of the card slot 105 is adapted to the size of the card column 109. The card column 109 is made of aluminum alloy. When the compression spring 107 rebounds, it will drive the card column 109 to move and snap into the card slot 105 through the sliding plate 108. The card column 109 made of aluminum alloy has high strength and is not easy to be damaged.

[0030] A specific application of this embodiment is: placing the copper alloy raw material in the special-shaped profile mold 3, turning on the motor 5 through the control panel 2, the motor 5 drives the threaded rod 6 to rotate through its output shaft, the threaded rod 6 rotates and drives the vertical rod 7 to move downward, the vertical rod 7 moves downward and drives the cross bar 8 to move downward, the cross bar 8 moves downward and drives the die roller 9 to move downward, the die roller 9 moves downward and contacts with the special-shaped profile mold 3 at the beginning and drives the special-shaped profile mold 3 to move downward, the special-shaped profile mold 3 moves downward and squeezes the elastic spring 104 to make it gradually tightened, and when the special-shaped profile mold 3 moves downward and drives its front end slot 105 to fit with the clamping column 109, the tightened compression spring 107 will rebound and drive the clamping column 109 to clamp into the slot 105 to fix the special-shaped profile mold 3, At this time, when the die roller 9 moves downward again, it will cooperate with the special-shaped profile mold 3 to die the copper alloy inside it. After the die die is completed, the motor 5 is turned on through the control panel 2 to drive the threaded rod 6 to reverse. The threaded rod 6 reverses and drives the vertical rod 7 to move upward. The vertical rod 7 moves upward and drives the cross bar 8 and the die roller 9 to move upward. At this time, the pull rod 1010 can be pulled toward the front end. The pull rod 1010 will drive the sliding plate 108 to move toward the front end, and the compression spring 107 will be tightened again. The movement of the sliding plate 108 toward the front end will drive the clamping column 109 to leave the clamping slot 105. At this time, the elastic spring 104 rebounds and drives the special-shaped profile mold 3 to bounce upward. The shock generated when the special-shaped profile mold 3 bounces upward makes the copper alloy therein loose, which is convenient for the subsequent removal of the copper alloy after die die pressing.
