Description

Technical Field

[0001] The utility model relates to the technical field of hot extrusion dies, in particular to a hot extrusion die for a guide rail aluminum profile. Background Art

[0002] Hot extrusion is the process of heating the metal material to the hot forging temperature for extrusion, that is, heating the blank to a temperature above the recrystallization temperature of the metal before extrusion. The mold is used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain various molds and tools for the required products.

[0003] The utility model patent with publication number CN216369573U discloses a hot extrusion die for guide rail aluminum profiles, which is mainly composed of a guide plate and a die body. This technical solution uses the flow limiting step and the stepped design of the guide plate to ensure that the aluminum flow can still be extruded out of the profile outlet at the same speed when passing through the inside of the forming cavity, avoiding the uneven distribution of metal components on the outer surface of the product due to the large difference in cross-sectional wall thickness during aluminum flow extrusion, resulting in color difference and surface unevenness, thereby improving the feel of the product and reducing color difference.

[0004] The hot extrusion die for guide rail aluminum profiles disclosed in the above-mentioned document has the following defects: during the forming process of the guide rail aluminum profile, misalignment between the guide plate and the die body can easily cause some errors in the production of the guide rail aluminum profile, affecting product quality, and even causing the guide rail aluminum profile to deform during the hot pressing process, thereby causing material waste and affecting processing efficiency.

[0005] It can be seen from this that the existing guide rail aluminum profile hot extrusion die does not have a good positioning structure, and it is necessary to improve the existing deficiencies and provide a guide rail aluminum profile hot extrusion die. Utility Model Content

[0006] The purpose of the present invention is to provide a hot extrusion die for a guide rail aluminum profile, so as to at least solve the problems raised in the above background technology to a certain extent.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a guide rail aluminum profile hot extrusion die, comprising an upper die and a lower die, wherein the outer surface of the upper die is provided with a mounting hole, a positioning assembly is arranged inside the mounting hole, an upper die core is arranged at one end of the upper die, a positioning groove is provided on the outer surface of the lower die, and the upper die is mounted on the lower die through the positioning assembly.

[0009] Furthermore, the positioning assembly includes a connecting tube, which is a single-sided closed tube body. The connecting tube is installed inside the mounting hole, one end of the connecting tube passes through the mounting hole and is installed inside the positioning groove, an airbag is installed inside the connecting tube, a cover is installed at one end of the airbag, a key is installed on the outer surface of the airbag, a slide groove is provided on the outer surface of the connecting tube, the key is slidably connected inside the slide groove, and a first connecting plate and a second connecting plate are provided inside the connecting tube.

[0010] Furthermore, a valve core is provided in the middle of the first connecting plate, and a stopper is abutted on the lower surface of the first connecting plate. A connecting rod is installed on the lower surface of the stopper, and one end of the connecting rod passes through the second connecting plate and extends downward. A spring is sleeved on the outer surface of the connecting rod, and one end of the spring is installed on the lower surface of the stopper, and the other end of the spring is installed on the upper surface of the second connecting plate.

[0011] Furthermore, an anti-drop block is provided at one end of the connecting rod, and air inlet holes are provided on the outer surfaces of the second connecting plate and the cover body.

[0012] Furthermore, a threaded hole is opened on the outer surface of the connecting tube, and the threaded holes are set to two and symmetrically distributed. The internal threads of the threaded holes are connected to a one-way screw, one end of the one-way screw is provided with a knob, and the other end of the one-way screw is provided with a clamping plate.

[0013] Furthermore, an anti-slip layer is provided on the inner surface of the positioning groove.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model injects gas into the interior of the connecting tube through the exhaust pipe, so that the gas pushes the stopper to compress the spring through the valve core, and at the same time, the gas enters the interior of the airbag through the air inlet hole, causing the airbag to gradually expand. During the expansion of the airbag, the key position is pushed to move outward in the slide groove. When the outer surface of the airbag abuts the outer surface of the connecting tube, the gas injection is stopped, so that the spring recovers its elasticity and pushes the stopper to reset. At this time, the outer surface of the key position abuts the outer surface of the anti-slip layer, making the connection between the upper mold and the lower mold more stable and less prone to misalignment, thereby avoiding deformation of the guide rail aluminum profile during hot pressing, thereby causing material waste and affecting processing efficiency.

[0016] (2) The utility model rotates the knob to make the one-way screw move axially toward one end of the exhaust pipe with the threaded hole as the center, so that the outer surface of the clamping plate abuts against and fixes the outer surface of the exhaust pipe to avoid gas leakage during use.

[0017] 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

[0031] The positioning assembly 3 includes a connecting tube 301, which is a single-side closed tube body. The connecting tube 301 is installed inside the mounting hole. One end of the connecting tube 301 passes through the mounting hole and is installed inside the positioning groove 201. An air bag 302 is installed inside the connecting tube 301. A cover 303 is installed at one end of the air bag 302. A key 304 is installed on the outer surface of the air bag 302. A slide groove is opened on the outer surface of the connecting tube 301.

[0034] When the outer surface of the airbag 302 abuts against the outer surface of the connecting tube 301, the gas is stopped from being injected, so that the spring 3010 recovers its elasticity and pushes the stopper 308 to reset. At this time, the outer surface of the key 304 abuts against the outer surface of the anti-slip layer 202, making the connection between the upper mold 1 and the lower mold 2 more stable and less prone to misalignment, thereby preventing the guide rail aluminum profile from being deformed during the hot pressing process, thereby causing material waste and affecting the processing efficiency.

Gas is injected into the interior of the connecting pipe 301 through the exhaust pipe, so that the gas pushes the stopper 308 to compress the spring 3010 through the valve core 307, and at the same time, the gas enters the airbag 301 through the air inlet hole 3012. 2, so that the airbag 302 gradually expands. During the expansion of the airbag 302, the key position 304 is pushed to move outward in the slide groove. When the outer surface of the airbag 302 abuts the outer surface of the connecting tube 301, the gas injection is stopped, so that the spring 3010 recovers its elasticity and pushes the stopper 308 to reset. At this time, the outer surface of the key position 304 abuts the outer surface of the anti-slip layer 202, making the connection between the upper mold 1 and the lower mold 2 more stable and less prone to misalignment, thereby avoiding deformation of the guide rail aluminum profile during the hot pressing process, thereby causing material waste and affecting processing efficiency.
