[0026] Specifically, Figure 1 As shown, a controller 9 is fixedly connected to the upper surface of the support frame 1, and the operation of the cold extrusion forming die is conveniently controlled by the controller 9.

[0027] Specifically, Figure 1 As shown, a label 10 is bonded to the upper surface of the support frame 1 on one side of the controller 9, and the label 10 is used to facilitate understanding of relevant parameter information of the cold extrusion molding die.

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the extrusion mechanism 5 includes a hydraulic cylinder 51 fixedly connected to the outer surface of the support frame 1, the output end of the hydraulic cylinder 51 is fixedly connected to a lifting plate 52, the lifting plate 52 is slidably connected to the support frame 1, and two extrusion tools 53 are symmetrically fixedly connected to the lower surface of the lifting plate 52.

[0029] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the blocking mechanism 6 includes two reciprocating screws 61 symmetrically rotatably connected to the inner surface of the support frame 1, and the two reciprocating screws 61 are fixedly connected, the outer surface of the reciprocating screw 61 is threadedly connected with a blocking plate 62, the two blocking plates 62 are both slidably connected to the support plate 2, the inner surfaces of the two blocking plates 62 are slidably connected with a limit rod 63, the limit rod 63 is fixedly connected to the support frame 1, one end of the reciprocating screw 61 is fixedly connected with a one-way gear 64, the outer surface of the one-way gear 64 is meshedly connected with a rack 65, the two racks 65 are both slidably connected to the support frame 1, and the two racks 65 are both fixedly connected to the lifting plate 52.

[0030] When in use, the aluminum alloy profile is placed in the placement groove of the template 4, and the aluminum alloy profile is supported by the blocking plate 62, and then the hydraulic cylinder 51 is started, and the output end of the hydraulic cylinder 51 extends to drive the lifting plate 52 to move downward, and then the lifting plate 52 moves downward to drive the extrusion tool 53 to move downward, and the aluminum alloy profile is cold extruded. In this process, the lifting plate 52 moves downward to drive the rack 65 to move downward, and the one-way gear 64 is in a non-rotating state. After the aluminum alloy profile is cold extruded, the output end of the hydraulic cylinder 51 contracts to drive the lifting plate 52 to move upward, and then the lifting plate 52 moves upward to drive the extrusion tool 53 and The rack 65 moves upward, and in the process of moving upward, the rack 65 drives the one-way gear 64 to rotate, and then drives the reciprocating screw 61 to rotate, and then the reciprocating screw 61 rotates to drive the blocking plate 62 to move in the opposite direction, and the blocking state of the lower part of the template 4 is released. The formed aluminum alloy profile can fall into the collection box 8 under gravity for collection. When the blocking plate 62 moves in the opposite direction to the limit position, it moves in the opposite direction to restore the original position to block the lower part of the template 4. At this time, the lifting plate 52, the extrusion tool 53 and the rack 65 move up to the initial position. In this process, the blocking plate 62 moves stably through the limit rod 1 63;

[0031] The function of automatic unloading and collection of aluminum alloy profiles is realized. Through the cooperation of the reciprocating screw 61, the sealing plate 62, the limit rod 63, the one-way gear 64 and the rack 65, the lower part of the template 4 can be blocked or the blocking state can be released, and the aluminum alloy profile can be supported or the supporting state can be released, so that the formed aluminum alloy profile can be automatically unloaded and collected, and there is no need to manually take out the aluminum alloy profile, which is more time-saving and thus improves the processing efficiency of the aluminum alloy profile.

[0032] Specifically, Figure 2 and Figure 3 As shown, the thread grooves of the two reciprocating screw rods 61 are arranged in opposite directions, which can ensure that the blocking plates 62 move synchronously toward or in opposite directions to block the lower part of the template 4 or release the blocking state.

[0034] When replacing the template 4, the rotating block 72 is rotated, and the two-way screw rod 71 is rotated by the rotating block 72, and then the fixing plate 73 on the outside of the template 4 is moved in the opposite direction by the rotating two-way screw rod 71, and the fixed state of the template 4 is released, and the old template 4 can be removed, and then the new template 4 is plugged into the positioning rod 3. After the new template 4 contacts the support plate 2, the rotating block 72 is reversed to make the fixing plate 73 on the outside of the new template 4 move toward each other and contact the new template 4, and fix its position, so as to complete the replacement of the template 4. In this process, the fixing plate 73 is stably moved by the limiting rod 2 74;

[0035] The function of quick disassembly and assembly of the template 4 is realized. Through the cooperation of the bidirectional screw 71, the rotating block 72, the fixing plate 73 and the limiting rod 74, the template 4 can be quickly disassembled and assembled, which saves time and effort, and facilitates the replacement of the template 4.

[0036] Specifically, Figure 1 and Figure 4 As shown, the outer surface of the rotating block 72 is provided with anti-slip grooves to increase the contact friction with the fingers, thereby facilitating the rotation of the rotating block 72.

[0037] Working principle: When in use, the aluminum alloy profile is placed in the placement groove of the template 4, and the aluminum alloy profile is supported by the blocking plate 62, and then the hydraulic cylinder 51 is started, and the output end of the hydraulic cylinder 51 extends to drive the lifting plate 52 to move downward, and then the lifting plate 52 moves downward to drive the extrusion tool 53 to move downward, and the aluminum alloy profile is cold extruded. In this process, the lifting plate 52 moves downward to drive the rack 65 to move downward, and the one-way gear 64 is in a non-rotating state. After the aluminum alloy profile is cold extruded, the output end of the hydraulic cylinder 51 contracts to drive the lifting plate 52 to move upward, and then the lifting plate 52 moves upward to drive the extrusion tool 53 The rack 65 moves upward, and the rack 65 drives the one-way gear 64 to rotate when moving upward, thereby driving the reciprocating screw 61 to rotate, and then the reciprocating screw 61 rotates to drive the blocking plate 62 to move in the opposite direction, thereby releasing the blocking state of the lower part of the template 4, and the formed aluminum alloy profile can fall into the collection box 8 under gravity for collection. When the blocking plate 62 moves in the opposite direction to the limit position, it moves in the opposite direction to restore the original position, and blocks the lower part of the template 4. At this time, the lifting plate 52, the extrusion tool 53 and the rack 65 move up to the initial position, and then the new aluminum alloy profile can be placed in the placement groove of the template 4 for processing;

[0038] When replacing the template 4, rotate the rotating block 72, and the rotation of the rotating block 72 drives the bidirectional screw rod 71 to rotate, and then the rotation of the bidirectional screw rod 71 drives the fixed plate 73 on the outside of the template 4 to move in the opposite direction, so as to release the fixed state of the template 4, and then remove the old template 4, and then connect the new template 4 with the positioning rod 3. After the new template 4 contacts the support plate 2, reverse the rotating block 72 to make the fixed plate 73 on the outside of the new template 4 move toward each other and contact the new template 4, and fix its position, so as to complete the replacement of the template 4. In this process, the movement of the fixed plate 73 is stable through the limit rod 2 74.
