Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a forming die for aluminum profile processing. Background Art

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Many aluminum profiles are currently prepared by hot extrusion molding process. The main component of this method is the extrusion die. Aluminum profiles are made by extrusion die. Extrusion die is a kind of molding die, but its discharge method is achieved through extrusion. It is used to make pipes or special-shaped materials. The shape of the object is mainly processed by changing the physical state of the molded material.

[0003] After checking the public (announcement) number: CN217289843U, an aluminum profile extrusion die is disclosed. This technology discloses "an aluminum profile extrusion die, which includes a first die and a second die, the first die and the second die are connected in an interlocking manner, and a buffer groove is provided on the side of the first die away from the second die, and a buffer portion is provided on the inner wall of the buffer groove" and other technical solutions, which have "buffering treatment for the process of the aluminum rod entering the die and the aluminum rod being extruded in the die, facilitating the entry of the aluminum rod, avoiding damage and oxidation when entering the die and being formed and extruded in the die, and effectively avoiding the aluminum rod from accumulating on the outer wall of the die" and other technical effects;

[0004] When processing aluminum profiles of different specifications, suitable molds are required. Since the mold is usually installed inside the extrusion equipment and connected by flanges, it is troublesome to disassemble and assemble it during replacement, and the entire mold needs to be replaced, which affects the processing efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a forming die for processing aluminum profiles, which has the characteristics of only needing to replace the die core when processing different aluminum profiles, and the replacement of the die core is convenient and quick.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a forming mold for aluminum profile processing, including a rear mold, a front mold for matching is installed on the rear mold, a mold core is installed inside the rear mold, and a fixing mechanism is provided on the rear mold and used to fix the mold core, and the fixing mechanism includes:

[0007] A fastening assembly, including a fastener installed inside the rear mold and sleeved on the mold core;

[0008] A clamping assembly, comprising a clamping piece installed inside the rear mold and sleeved on the rear end of the fastener;

[0009] The adjusting component comprises a ring sleeve installed at the rear end of the fastener, wherein the outer wall of the ring sleeve is threadedly connected with the inner wall of the fastener, and insertion holes are arranged on both sides of the ring sleeve.

[0010] Preferably, the fastening assembly further comprises four slots distributed circumferentially on the fastener.

[0011] Preferably, the clamping assembly further comprises a clamping hole opened inside the clamping member.

[0012] Preferably, four circumferentially distributed positioning heads are fixed to the front end inner wall of the rear mold, and four circumferentially distributed positioning holes are provided on the front end outer edge of the fastener.

[0013] Preferably, four circumferentially distributed protrusions are fixed to the inner wall of the fastener, and four circumferentially distributed grooves are formed on the outer wall of the mold core.

[0014] Preferably, four circumferentially distributed limiting heads are fixed to the rear end outer edge of the front mold, and four circumferentially distributed limiting holes are opened at the front end outer edge of the mold core.

[0015] Preferably, an adjusting piece is installed at the rear end of the ring sleeve.

[0016] Beneficial Effects

[0017] The utility model provides a forming die for aluminum profile processing. Compared with the prior art, it has the following beneficial effects:

[0018] (1) After the mold core passes through the adjustment component, the clamping component and the fastening component in sequence and is installed inside the rear mold, the clamping member can be pushed inward by rotating the ring sleeve clockwise. At the same time, the clamping member squeezes the fastener so that the fastener can tighten the internal mold core, thereby fixing the mold core inside the rear mold. The same is true when the mold core is removed. It is only necessary to rotate the ring sleeve counterclockwise, so that the mold core can be replaced when processing different aluminum profiles, and the replacement of the mold core is convenient and quick.

[0019] (2) After the fastener is installed inside the rear mold, the positioning head cooperates with the positioning hole to limit the rotation of the fastener after installation, and the protrusion cooperates with the groove to limit the movement of the mold core after installation, so that the fastener is more firmly fastened to the mold core and is not easy to loosen.
