Technical Field

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

[0002] Aluminum profile extrusion molds are one of the most important tools in the production of aluminum alloy profiles. They are widely used in industries such as construction, automobiles, aviation, electronics, and home appliances. They are used to heat aluminum alloy billets to a certain temperature and then force them through a mold under high pressure to form aluminum profiles with specific cross-sections and dimensions.

[0003] In the prior art, such as Chinese Patent No. CN202422539424.7, this utility model relates to the field of extrusion molding die technology, and in particular to an aluminum profile extrusion molding die, including a molding mechanism. The molding mechanism includes a die base, the upper surface of which has a first groove. A demolding mechanism is installed on the inner wall of the first groove. The demolding mechanism includes a pressure block, the surface of which is in contact with the inner wall of the first groove. A first connecting block is fixedly connected to the right side surface of the pressure block, and a first cylinder is fixedly connected to the left side surface of the first connecting block. A pointed cone is fixedly connected to the output end of the first cylinder. A rotating mechanism is installed on the lower surface of the die base. This utility model can easily remove and deliver the molded part without dropping or shaking, improving the practicality of the device.

[0004] While the above solutions offer advantages, the lack of die-changing components in the actual production process makes it difficult for operators to change the die head.

[0057] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0059] Example 1, as Figures 1-7 As shown, this utility model provides an aluminum profile extrusion molding die, including: a device body 1, a guide rail 111, a first hydraulic push rod 112, a push plate 113, a mold changing assembly, and a cutting assembly;

[0060] The guide rail 111 is fixedly installed on the top of the device body 1, the first hydraulic push rod 112 is fixedly embedded in the left side of the device body 1, the push plate 113 is fixedly connected to the right side of the first hydraulic push rod 112, the push plate 113 is slidably connected to the inside of the guide rail 111, and the right side of the guide rail 111 is located on the left side of the mold changing assembly.

[0061] In this embodiment, the operator can first place the aluminum material inside the guide rail 111 and place it on the right side of the push plate 113. Then, through the drive system of the first hydraulic push rod 112, the first hydraulic push rod 112 is activated so that when it extends, it can push the push plate 113 to slide to the right inside the guide rail 111. When the push plate 113 slides, it can push the aluminum material to move to the right synchronously inside the guide rail 111, so that the aluminum material can be extruded and formed through the die head 103 inside the die changing assembly.

[0062] In addition, the mold changing assembly includes: a rotating rod 101 is movably embedded inside the device body 1, and a mounting plate 102 is fixedly sleeved on the outer surface of the rotating rod 101. The mounting plate 102 is movably embedded in the top side inside the device body 1. Multiple mold heads 103 are movably embedded inside the mounting plate 102. Positioning pins 104 are fixedly connected to both sides of the outer surface of the multiple mold heads 103. In this design, the positioning pins 104 can ensure that the mold head 103 is accurately positioned when it is installed inside the mounting plate 102. The multiple positioning pins 104 are divided into two groups, one of which is movably embedded inside the mounting plate 102.

[0063] The mounting plate 102 has mounting parts 105 movably embedded inside. Multiple mounting parts 105 are movably attached to the outer surface of the mold head 103 on opposite sides. In this design, the cooperation between the mounting parts 105 and the positioning posts 104 ensures that the mold head 103 maintains a stable position during operation, preventing displacement of the mold head 103 due to shaking or pressure changes. Multiple mounting parts 105 are movably sleeved on the outer surface of another set of positioning posts 104. Bolts 106 are threaded to both sides of the interior of multiple mounting parts 105. Multiple threaded grooves 107 are opened inside the mounting plate 102, and multiple bolts 106 are matched with the threaded grooves 107.

[0064] In addition, a worm gear 110 is fixedly installed on the left side of the rotating rod 101, and a motor 108 is fixedly installed on the bottom side of the inside of the device body 1. A worm 109 is fixedly installed on the rear side of the output shaft of the motor 108. The worm 109 is movably embedded in the top side of the inside of the device body 1 and meshes with the worm gear 110. In this design, the rotating rod 101 can have a self-locking function through the transmission characteristics of the worm 109 and the worm gear 110, so that the rotating rod 101 will not rotate on its own due to external forces or other disturbances in the system after the motor 108 stops running.

[0065] In this embodiment, the operator can first embed the mold head 103 into the mounting plate 102, so that the positioning post 104 on the inner side of the mold head 103 can be embedded in the mounting plate 102. Then, the operator picks up the mounting part 105 and embeds it into the mounting plate 102 at the same time, so that the mounting part 105 fits against the outer surface of the mold head 103 and can cover the positioning post 104 on the outer side of the mold head 103. Then, the operator can rotate the bolt 106 so that it can be embedded into the threaded groove 107 to fix the mold head 103 inside the mounting plate 102.

[0066] Example 2, as Figures 1-7As shown, the cutting assembly includes: a gantry frame 2 is fixedly embedded in the top side of the device body 1, a second hydraulic push rod 201 is fixedly embedded in the top side of the gantry frame 2, a connecting plate 202 is fixedly installed at the bottom of the second hydraulic push rod 201, and a cutting blade 203 is fixedly installed at the bottom of the connecting plate 202. In this design, the cutting blade 203 can cut the extruded aluminum material, and the cutting blade 203 is movably embedded inside the gantry frame 2.

[0067] In addition, two third hydraulic push rods 204 are fixedly installed on the top side inside the device body 1. A support plate 205 is fixedly installed on the top of the two third hydraulic push rods 204. In this design, the support plate 205 can support the aluminum profile during cutting. The support plate 205 is slidably connected inside the gantry frame 2. A soft pad 206 is provided on the top of the support plate 205.

[0068] It should be noted that the two third hydraulic push rods 204 are synchronously controlled by a PLC controller to achieve synchronous extension or retraction of the two third hydraulic push rods 204.

[0069] In this embodiment, when the aluminum material is extruded through the die head 103, the formed aluminum material will pass through the gantry frame 2. After the aluminum material is extruded to a suitable length, the personnel can start the second hydraulic push rod 201 through the drive system of the second hydraulic push rod 201, so that when it extends, it can drive the cutting blade 203 to descend through the connecting plate 202, so as to cut the aluminum profile through the cutting blade 203.

[0070] Working principle: When the mold head 103 is installed, the operator can start the motor 108 through the power supply system. During operation, the motor 108 will drive the worm gear 109 through the output shaft, and the worm gear 109 will drive the rotating rod 101 through the worm wheel 110. The rotating rod 101 will then drive the mounting plate 102 to rotate. When the mounting plate 102 rotates, it will drive multiple mold heads 103 to rotate in a circle, so that multiple mold heads 103 can sequentially fit against the right side of the guide rail 111, thereby realizing the automatic replacement of multiple mold heads 103. Through the structure of the mounting plate 102 and the worm gear 109, multiple mold heads 103 can be automatically replaced under the rotation of the mounting plate 102, reducing manual intervention and improving the level of automation. This not only improves production efficiency, but also effectively reduces the workload of operators.

[0071] In use, when the cutting blade 203 is cutting the extruded aluminum profile, the operator can activate the third hydraulic push rod 204 through the PLC controller. This push rod extends and pushes the support plate 205 upward inside the gantry 2. As the support plate 205 slides, it causes the soft pad 206 to adhere to the bottom of the aluminum profile at the cutting point, thus supporting the aluminum profile. The structure of the cutting blade 203 and the support plate 205 not only ensures good support for the aluminum profile during cutting, preventing uneven or inaccurate cutting caused by excessive impact from the cutting blade 203, but also ensures that the aluminum profile is well supported during cutting. At the same time, the soft pad 206, as a flexible material, adheres to the bottom of the aluminum profile, effectively absorbing and dispersing the impact force that may be generated during the cutting process, reducing the deformation of the aluminum profile.

[0072] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
