Description

Technical Field

[0001] This utility model relates to the field of aluminum profile extrusion molding technology, and in particular to an extrusion die for aluminum profile production. Background Technology

[0002] The principle of aluminum profile extrusion is based on the theory of metal plastic deformation. External force is used to cause the aluminum billet to flow directionally within the mold cavity, thereby obtaining a profile with the desired cross-sectional shape and size. Its core processes include material preparation, mold design, extrusion deformation, and post-processing. During extrusion, the aluminum billet is heated to the extrusion temperature, and then forced into the extrusion mold by a pressure mechanism for shaping.

[0003] Currently, in existing technologies, the installation between the extrusion die and the aluminum profile extrusion press is mostly achieved using multiple bolts. When it is necessary to change the die to process aluminum profiles with different cross-sectional shapes, the heat generated during the operation of the aluminum profile extrusion press makes the bolts difficult to remove, and both disassembly and installation are cumbersome. Therefore, this utility model proposes an extrusion die for aluminum profile production to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an extrusion die for aluminum profile production. By setting the forming die core in the die core groove on the forming die base, and then setting a clamping mechanism consisting of a bidirectional screw, a moving block, and a locking clamping block in the mounting base, the moving block can be driven to move by rotating the bidirectional screw, so that the locking clamping block is inserted into the locking hole at the docking hole to fix the forming die core.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0006] An extrusion die for aluminum profile production includes a forming die base and a forming die core. The forming die base is fixedly installed on an aluminum profile extrusion press. The forming die base has a die core groove, and a forming die core is provided in the die core groove. Positioning grooves are symmetrically arranged in the die core groove. Positioning blocks are provided on both sides of the forming die core. The positioning blocks are adapted to the positioning grooves. A through groove is provided at the lower end of the forming die base. A mounting seat is provided in the through groove. A bidirectional screw is rotatably provided in the mounting seat. Moving blocks are symmetrically and threadedly connected to the bidirectional screw. A locking clamp is provided on the inner side of the upper end of the moving block. The lower end of the locking clamp is slidably connected to the interior of the mounting seat. A mating hole is provided on both side walls of the upper end of the forming die base. The mating hole communicates with the positioning groove. A locking hole is provided on the positioning block. Both the mating hole and the locking hole are adapted to the locking clamp.

[0007] A further improvement is that: the forming mold base inside the mold core groove is symmetrically provided with slots, and the bottom of the forming mold core is provided with a locking block that matches the slot.

[0008] A further improvement is that a demolding groove is provided on the forming mold base below the mold core groove, and the demolding groove is connected to the mold core groove.

[0009] A further improvement is that a drive mechanism is installed on the outer wall of the mounting base, and the drive mechanism controls the bidirectional screw to rotate inside the mounting base.

[0010] A further improvement is that a top block is provided at the bottom of the molding core, and the lower end of the top block extends to the middle section of the demolding groove.

[0011] A further improvement is that: connecting blocks are provided on both sides of the upper end of the forming mold base, and a first fixing bolt is provided on the connecting block; a second fixing bolt is provided at the four corners of the lower end of the forming mold base; and the forming mold base is fixedly installed with the aluminum profile extrusion machine by the first fixing bolt and the second fixing bolt.

[0012] The beneficial effects of this utility model are as follows: This utility model sets the forming mold core in the mold core groove on the forming mold base, and sets a mounting seat in the through groove at the lower end of the forming mold base. Then, a clamping mechanism consisting of a bidirectional screw, a moving block and a locking clamping block is set in the mounting seat. The bidirectional screw can drive the moving block to move, so that the locking clamping block is inserted into the locking hole at the docking hole to fix the forming mold core. The bidirectional screw, moving block and locking clamping block are set in a low position, which is less affected by the working temperature of the aluminum profile extrusion press, and is not prone to drive jamming. It can also achieve quick fixing of the forming mold core. The forming mold core can be quickly disassembled and assembled. Attached Figure Description

[0020] When installing the extrusion die for aluminum profile production of this utility model, the forming die core 2 is installed in the die core groove 3, ensuring that the positioning blocks 5 on both sides of the forming die core 2 are engaged in the positioning groove 4. Then, the bidirectional screw 8 is controlled to rotate in the mounting base 7 by the drive mechanism. Then, the two moving blocks 9 are brought closer to each other on the bidirectional screw 8, so that the locking clamping block 10 passes through the docking hole 11 and enters the locking hole 12, thereby clamping the forming die core 2 in the die core groove 3.

[0021] The molding base 1 located below the mold core groove 3 is symmetrically provided with slots 13, and the bottom of the molding mold core 2 is provided with a locking block 14 that matches the slots 13. By setting the mold core groove 3 and the locking block 14 to cooperate, the positioning stability and accuracy of the molding mold core 2 can be further improved when the molding mold core 2 is installed in the mold core groove 3.

[0022] A drive mechanism is installed on the outer wall of the mounting base 7, which controls the rotation of the bidirectional screw 8 within the mounting base 7. In this invention, the drive mechanism comprises a worm gear, a worm, and a drive source. The worm gear is mounted on the shaft of the bidirectional screw 8, the worm is rotatably mounted on the mounting base 7, and the drive source consists of a motor and a handwheel. The drive source drives the worm to rotate, thereby causing the worm to drive the rotation of the bidirectional screw 8. The worm gear transmission has a self-locking capability.

[0023] The upper end of the forming mold base 1 is provided with connecting blocks 17 on both sides, and the connecting blocks 17 are provided with first fixing bolts 18. The lower end of the forming mold base 1 is provided with second fixing bolts 19 at the four corners.

A top block 16 is provided at the bottom of the forming mold core 2, and the lower end of the top block 16 extends to the middle section inside the demolding groove 15. By providing the demolding groove 15, this utility model can easily lift the forming mold core 2 from the demolding groove 15, which facilitates the disassembly of the forming mold core 2.

[0027] This invention sets the forming mold core 2 in the mold core groove 3 on the forming mold base 1, and sets a mounting base 7 in the through groove 6 at the lower end of the forming mold base 1. Then, a clamping mechanism consisting of a bidirectional screw 8, a moving block 9, and a locking clamp 10 is set in the mounting base 7. The bidirectional screw 8 rotates to drive the moving block 9 to move, so that the locking clamp 10 is inserted into the locking hole 12 at the docking hole 11 to fix the forming mold core 2.
