[0034] Example 1

[0035] Reference Figures 1-9 This embodiment provides an aluminum alloy profile extrusion device, including a worktable 100, on which a first channel 101 and a second channel 102 are vertically arranged, the first channel 101 and the second channel 102 communicating with a fixed groove 103, a support platform 104 slidably connected in the first channel 101, a mold 200 disposed in the support platform 104, a feeding cylinder 105 slidably connected in the second channel 102, a guide hole 105a disposed in the feeding cylinder 105, and a shaft material 300 disposed in the discharge hole 105a; it also includes an extrusion shaft 400, the extrusion shaft 400 being positioned corresponding to the guide hole 105a.

[0036] The extrusion shaft 400 can be hydraulically driven.

[0037] It should be noted that both the support platform 104 and the feeding cylinder 105 are controlled to move by independent hydraulic push rods.

[0038] The support platform 104 is provided with a bottom circular groove 104a, and a placement through groove 104b is provided above the support platform 104, which communicates with the bottom circular groove 104a. A vertical groove 104c is provided on the side wall of the placement through groove 104b.

[0039] Furthermore, the mold 200 includes a first mold assembly 201 and a second mold assembly 202. The second mold assembly 202 is provided with a first slot 202a. A core 202c is connected to the first slot 202a through a rib 202b. The first mold assembly 201 is provided with a second slot 201a and a third slot 201b. The rib 202b passes through the third slot 201b and its end is placed in the second slot 201a.

[0040] The second mold 202 has a ring shaft 202d on its side, which is embedded in the vertical groove 104c.

[0041] The mold 200 consists of two parts: a first mold 201 and a second mold 202. The core 202c can be replaced by replacing the second mold 201, and the profile structure can be changed by using different combinations of the core 202c and the second slot 201a.

[0042] It should be noted that the third slot 201b is larger than the second slot 201a. The core 202c is placed in the second slot 201a. The shaft material 300 is extruded into the first slot 202a by the extrusion shaft 400, and then extruded through the gap between the third slot 201b, the second slot 201a and the core (202c) to form the shape.

[0043] The support platform 104 is provided with a discharge chute at the second slot 201a.

[0044] After the first mold 201 and the second mold 202 are assembled, they are placed in the bottom circular groove 104a from above, and fixed by being embedded in the vertical groove 104c by the ring shaft 202d.

[0045] The end of the feeding cylinder 105 is provided with a docking shaft 105b, the position of which corresponds to the second mold assembly 202, and the guide hole 105a corresponds to the first slot hole 202a.

[0046] It should be noted that the support platform 104 moves along the first channel 101 to the fixed groove 103 and is fixed. The docking shaft 105b corresponds to the bottom circular groove 104a. The feeding cylinder 105 is pushed to move the docking shaft 105b into the bottom circular groove 104a, and the docking shaft 105b docks with the second assembly mold 202.

[0047] The first mold 201 is provided with a slot 201c, and the slot 201c is provided with a sloping groove 201d along its inner wall. A magnetic surface 201e is provided at the bottom of the sloping groove 201d. A first limiting plate 203 is provided in the slot 201c. A central groove 203a is provided in the middle of the first limiting plate 203. Fan-shaped grooves 203b are provided on both sides of the central groove 203a. A side shaft 203c is provided on the side of the first limiting plate 203. The side shaft 203c is embedded in the sloping groove 201d.

[0048] The central angle of the sector groove 203b is 90°, and the side shaft 203c is made of magnetic material.

[0049] When the first limiting plate 203 is pushed upward, the side shaft 203c will move along the inclined groove 201d, and the first limiting plate 203 will rotate and move upward.

[0050] Furthermore, the central angle corresponding to the inclined groove 201d is 90°.

[0051] The second mold 202 is provided with a square column 202e, a round shaft 202f is provided on the top of the square column 202e, and a first arc plate 202g is provided on both sides of the top of the round shaft 202f.

[0052] There are two first arc plates 202g, and the central angle corresponding to a single first arc plate 202g is 90°.

[0053] The diameter of the circular shaft 202f is greater than the length of the diagonal of the square prism 202e.

[0054] It also includes a push plate 204, which includes a central circular plate 204a and second arc plates 204b disposed on both sides of the central circular plate 204a.

[0055] The first arc plate 202g and the second arc plate 204b have the same structure and dimensions, and the middle circular plate 204a and the circular shaft 202f have the same structure and dimensions.

[0056] One side of the push plate 204 is connected to the second mold 202 via a spring 204d. A square hole 202c is provided on the middle circular plate 204a, and a square column 202e passes through the square hole 202c. The push plate 204 and the first arc plate 202g are placed at 90° angles to each other.

[0057] Spring 204d exerts an upward thrust on push plate 204, and the top of push plate 204 contacts the bottom surface of round shaft 202f.

[0058] Specifically, in the initial state, the side shaft 203c is attracted by the magnetic surface 201e and placed at the bottom of the inclined slot 201d. At this time, the square post 202e is aligned with the slot 201c, and the position of the first arc plate 202g corresponds to the position of the sector slot 203b. Therefore, during the assembly process, the first arc plate 202g passes through the sector slot 203b, and then the first limiting plate 203 contacts the push plate 204. Since the side shaft 203c is attracted and fixed by the magnetic surface 201e, and since the push plate 204 is fixed, the side shaft 203c is fixed by the magnetic surface 201e. The positions of plate 204 and sector groove 203b do not correspond, so the push plate 204 is pressed down. Then the first arc plate 202g completely passes through the sector groove 203b, and the upward elastic force of the spring 204d received by the push plate 204 gradually increases, pushing the side shaft 203c away from the magnetic surface 201e. The side shaft 203c moves and rotates along the inclined groove 201d. During the rotation, the first limiting plate 203 rotates, and the first arc plate 202g is misaligned with the sector groove 203b.

[0059] When the side shaft 203c moves to the top of the inclined groove 201d, the first limiting plate 203 rotates 90° relative to the initial state. At this time, the position of the push plate 204 corresponds to the position of the sector groove 203b. The push plate 204 is embedded in the sector groove 203b under the action of the spring 204d. At this time, the first limiting plate 203 is below the first arc plate 202g. Since the push plate 204 cannot rotate, the first limiting plate 203 cannot rotate. Therefore, the first limiting plate 203 cannot move downward to leave space for the first arc plate 202g to leave, thus forming a connection and fixation.

[0060] Furthermore, a positioning shaft can be provided on the second assembly mold 202, and a positioning groove can be provided on the first assembly mold 201 to ensure that the two are correctly aligned and assembled.

[0061] It also includes an unlocking component 500, which includes a push shaft 501 and a horizontal pressure plate 502 disposed on the push shaft 501.

[0062] The first assembly mold 201 is also provided with an unlocking hole 202h, which is connected to the slot 201c.

[0063] Furthermore, if disassembly is required, the unlocking component 500 is inserted into the slot 201c through the unlocking hole 202h and pushed. The push shaft 501 presses the push plate 204 down away from the fan-shaped groove 203b. Then, the horizontal pressure plate 502 contacts and squeezes the first limiting plate 203, causing the first limiting plate 203 to move downward and rotate 90 degrees. At this time, the position of the fan-shaped groove 203b corresponds to the position of the first arc plate 202g, so that the second mold 202 and the first mold can be separated.

[0064] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
