[0002] The large cantilever profile is formed by hot extrusion of the ingot through a diverter die. The diverter die is divided into an upper die and a lower die. At present, the cantilever diverter die is normally a flat die, and the opening position on one side must support the entire inner area. If the mold strength is not enough, it will cause the opening to break and cause the mold to be scrapped. In addition, during the working process of the diverter die, the mold temperature is often too high, which often requires a long period of static cooling, thereby extending a large amount of process time. Therefore, we proposed an oblique closed diverter die for large cantilevers to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Multiple heat dissipation cavities 4 are provided on the lower mold 1 and the upper mold 2 for heat dissipation and dust prevention of the mold. Fixed cavities 6 are also provided on both sides of the heat dissipation cavity 4. A rotating handle 5 is provided in the middle of the heat dissipation cavity 4. The rotating handle 5 is provided to drive the connecting member 8 to move and adjust. A bearing is welded in the middle of the inner wall of one end of the heat dissipation cavity 4. The end of the rotating handle 5 rotates in the bearing. Both sides of the boundary of the position where the bearing is located are open. A photosensitive sensor 51 is embedded in the rotating handle 5 (when the photosensitive sensor 51 is blocked for a single number of times and loses the signal, it can be detected by The electric signal controls the electric push rod 74 to shorten and the power supply 73 to shut down. When the signal is blocked several times and lost, the electric push rod 74 can be extended by the electric signal. The position of the photosensitive sensor 51 is located on the same straight line as the corner position of the slide slot 61, and a connecting piece 8 threadedly driven therewith is provided on the outer wall of the rotating handle 5. The connecting piece 8 is provided to drive the baffle 7 to move and adjust. The connecting piece 8 is a short shaft. An external thread is provided on the outer wall of the rotating handle 5, and an internal thread matching the external thread is provided on the inner wall of the connecting piece 8.

[0028] Baffles 7 are provided on both ends of the connecting member 8. The baffles 7 are provided to adjust the heat dissipation of the mold and to prevent dust from the heat dissipation cavity 4. A mounting plate 72 is welded between the inner walls of one end of the baffle 7. A power supply 73 and an electric push rod 74 are installed on one side of the mounting plate 72 by screws (when the electric push rod 74 is in the farthest output distance state, the power supply 73 can be started by controlling the electric signal). A positioning ring 75 is bonded to the movable end of the electric push rod 74. The positioning ring 75 is provided to limit and adjust the rotating shaft 71. A first contact sensor is embedded on the mounting plate 72 at a position relative to the positioning ring 75. The first contact sensor is connected to the electric push rod 74 and the power supply 73 by electrical signals. The positioning ring 75 is provided with a silicon steel sheet electrically connected to the power supply 73. A rotating shaft 71 is provided at the connection between the connecting member 8 and the baffle 7. The rotating shaft 71 is provided to facilitate the synchronous movement and active adjustment of the baffle 7 and the connecting member 8. The outer surface of the rotating shaft 71 The surface is an iron sheet, and the positioning ring 75 is connected to the rotating shaft 71. One side of the mounting plate 72 is a cavity structure in the baffle 7, and the rotating shaft 71 is located therein. A protective cover is welded on the side wall of the other side of the mounting plate 72, and the power supply 73 and the electric push rod 74 are located therein. The rotating shaft 71 is set through the connecting member 8 and is bonded and fixed thereto. The end of the rotating shaft 71 is rotatably set between the inner wall of the baffle 7; the other end of the connecting member 8 is movable in the fixed cavity 6 and a sliding bolt 62 is set therebetween. The setting of the sliding bolt 62 is to guide and limit the baffle 7, and also to guide and limit the movement of the connecting member 8. The top wall and the bottom wall of the fixed cavity 6 are both provided with a sliding groove 61, and the end of the sliding groove 61 is embedded with a second contact sensor. The setting of the second contact sensor can control the stopping of the power supply 73 and the stopping of the electric push rod 74 through an electrical signal. The sliding bolt 62 is set through the baffle 7 and is rotatably connected thereto, and the two ends of the sliding bolt 62 slide in the sliding grooves 61 on both sides respectively.

[0029] In this embodiment, inclined closures are respectively provided in the lower mold 1 and the upper mold 2, and the opening of the cast cantilever aluminum profile is supported by two inclined closure members 3, thereby improving the overall strength of the diverter mold and reducing factors causing breakage at the opening.

[0030] Before casting the cantilever aluminum profile, the handle 5 can be rotated to drive the connecting member 8 to move outward, and the connecting member 8 simultaneously drives the baffles 7 on both sides to move inward. Figure 5 When the light sensor 51 is located, the light sensor 51 is blocked by the connecting member 8. At this time, the light sensor 51 sends a signal to start the electric push rod 74, so that it drives the positioning ring 75 to move to the upper side. Figure 6When the positioning ring 75 touches the first contact sensor, the first contact sensor is triggered, and a command is sent to stop the electric push rod 74. At the same time, a command is sent to stop the power supply 73. At this time, the suction between the silicon steel sheet and the iron sheet disappears, and the connection member 8 and the baffle 7 are also in a rotatable and adjustable state; then, the connection member 8 continues to move outward with the handle 5, so that the baffle 7 begins to expand outward, and the sliding bolt 62 begins to move obliquely toward the slide groove 61 to cooperate with the expansion movement of the baffle 7, so that a large area of ​​the heat dissipation cavity 4 is unblocked to accelerate the heat dissipation, and the connection member 8 can stop when it moves to the end of the handle 5;

[0031] When heat dissipation is not required, the handle 5 is rotated in the opposite direction to drive the connecting member 8 to move inward, and the connecting member 8 simultaneously drives the baffles 7 on both sides to move outward. Figure 5 When the handle 5 passes the position of the photosensor 51, the photosensor 51 is blocked by the connecting piece 8 again. At this time, the photosensor 51 sends a signal to start the electric push rod 74 and extend it to the longest distance, so that the shaft 71 and the positioning ring 75 contact each other. Then, the power supply 73 is started, and the current flows through the silicon steel sheet, generating suction between the steel sheet of the shaft 71, so that the shaft 71 and the baffle 7 cannot continue to rotate. Then, under the continued driving of the handle 5, the baffle 7 moves synchronously with the connecting piece 8. Figure 5 When the connecting member 8 moves to contact with the bearing, the handle 5 stops rotating, and the sliding bolt 62 is located at the end of the slide slot 61 at this time, the second contact sensor is triggered, the power supply 73 stops, and the electric push rod 74 stops at the farthest output distance. At this time, the baffles 7 on both sides are also completely retracted, that is, Figure 5 The horizontal state shown can provide a certain dust-proof effect for the heat dissipation cavity 4 .
