[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-7 As shown, this embodiment of the invention provides a conformal salt-core aluminum tube die-casting mold structure, including a mounting frame 1; a mounting base 2 is fixedly connected to one side of the mounting frame 1; a clamping mechanism 5 is placed on one side of the mounting base 2; a positioning mechanism 6 is provided on the side of the mounting frame 1 away from the clamping mechanism 5; a second placement plate 4 and a first placement plate 3 are fixedly connected to the upper and lower ends of the side of the mounting base 2 away from the clamping mechanism 5, respectively; an aluminum tube body 7 is provided on the inner side of the mounting frame 1, and the aluminum tube body 7 is in contact with the second placement plate 4, the first placement plate 3, and the positioning mechanism 6 during use. By setting the cooperation relationship between the positioning mechanism 6 and the mounting frame 1, the positioning mechanism 6 positions the aluminum tube body 7, reducing the misalignment caused by poor stability of the aluminum tube during placement, thus preventing low product yield and low production efficiency.

[0033] The positioning mechanism 6 includes a left slider 601, a right slider 602, an upper slider spring pin 603, a limiting rod 604, a lower slider insert 605, a moving mold insert one 606, a moving mold insert two 607, a connecting plate 608, a drive plate 609, a drive cylinder 610, a positioning cylinder 611, a clamping cylinder 612, a setting plate 613, and a setting frame 614. The left slider 601 and the right slider 602 are located on both sides of the inner cavity of the mounting frame 1. The clamping cylinder 612 is fixedly installed on both sides of the outer surface of the mounting frame 1, and the telescopic end of the clamping cylinder 612 passes through the mounting frame 1 and is fixedly connected to the opposite sides of the left slider 601 and the right slider 602. By setting the left slider 601 and the right slider 602 on both sides of the mounting frame 1, the left slider 601 and the right slider 602 are limited when they approach each other.

[0034] The lower slider insert 605 is fixedly connected to the bottom surface of the inner cavity of the mounting frame 1, and there are two lower slider inserts 605 symmetrically arranged. The limiting rod 604 is fixedly connected to the top surface of the mounting frame 1, and there are two limiting rods 604 corresponding to the lower slider inserts 605. The lower end of the limiting rod 604 passes through the mounting frame 1. The inner side of the upper end of the upper slider spring pin 603 is slidably connected to the outer side of the lower end of the limiting rod 604. By setting the upper slider spring pin 603 and the limiting rod 604 to cooperate with each other, the limiting rod 604 limits the upper slider spring pin 603, reducing the problem of the upper slider spring pin 603 deflecting when moving.

[0035] A spring is fitted on the outer side of the limiting rod 604, and the two ends of the spring are fixedly connected to the mounting frame 1 and the upper slider pin 603 on their respective sides. By setting the spring, the spring can elastically push the upper slider pin 603 to lock in place.

[0036] The bottom end of the upper slider spring pin 603 is provided with an angle; the outer surface of the upper slider spring pin 603 fits with the inner side of the upper end of the aluminum tube body 7. By providing an angle on the outer side of the bottom end of the upper slider spring pin 603, the upper slider spring pin 603 is moved when it comes into contact with other parts through the angle, and then the upper slider spring pin 603 is locked when it is reset.

[0037] Moving mold insert 1 606 and moving mold insert 2 607 are disposed on the side of the inner cavity of the mounting frame 1 away from the second placement plate 4, and two moving mold inserts 1 606 and moving mold insert 2 607 are provided and symmetrical to each other; moving mold insert 1 606 and moving mold insert 2 607 are distributed at the upper and lower ends of the mounting frame 1; connecting plate 608 and driving plate 609 are slidably connected to the inner side of the end of the mounting frame 1 near moving mold insert 1 606 and moving mold insert 2 607 respectively; the two ends of connecting plate 608 and driving plate 609 pass through the mounting frame 1 and are fixedly connected to moving mold insert 1 606 and moving mold insert 2 607 respectively. By moving moving mold insert 1 606 and moving mold insert 2 607, they are limited from the side, thereby enhancing the positioning effect.

[0038] The setting frame 614 and setting plate 613 are respectively located on the outer side of the connecting plate 608 and the middle of the outer side of the drive plate 609; the setting frame 614 and setting plate 613 are fixedly connected to the outer surface of the mounting frame 1; the drive cylinder 610 and positioning cylinder 611 are respectively fixedly installed on the side of the setting frame 614 and setting plate 613 away from the mounting frame 1; the telescopic ends of the drive cylinder 610 and positioning cylinder 611 pass through the setting frame 614 and setting plate 613 respectively and are fixedly connected to the connecting plate 608 and drive plate 609 respectively. By cooperating with the connecting plate 608 and drive plate 609 respectively, the setting frame 614 and setting plate 613 limit the movement of the connecting plate 608 and drive plate 609, making the movement of the connecting plate 608 and drive plate 609 more stable.

[0039] The ends of moving mold insert 1 606 and moving mold insert 2 607 furthest from the drive cylinder 610 are rounded; the outer surface of the aluminum tube body 7 matches the rounded corners. By matching the rounded corners with the aluminum tube body 7, the contact area is increased, thereby improving the positioning effect.

[0040] The ends of the second placement plate 4 and the first placement plate 3, away from the mounting base 2, are set with rounded corners; the outer surface of the aluminum tube body 7 matches the rounded corners. By setting the rounded corners to match the aluminum tube body 7, the contact with the aluminum tube body 7 around the perimeter is increased, making the rounded corners more stable in limiting the aluminum tube body 7.

[0041] The clamping mechanism 5 includes a mounting shell 501, a clamp 502, a mounting post 503, a moving plate 504, a linkage plate 505, and a placement cylinder 506. The mounting shell 501 is clamped on the back of the mounting base 2. The clamp 502 is located at both ends of the inner side of the mounting shell 501. The mounting post 503 and the linkage plate 505 are respectively rotatably connected to the middle end of the clamp 502 and the end near the mounting shell 501. The mounting post 503 is fixedly connected to the inner side of one end of the mounting shell 501. The two ends of the moving plate 504 are rotatably connected to the end of the linkage plate 505 away from the clamp 502, and the moving plate 504 is slidably connected to the inner side of the mounting shell 501. The placement cylinder 506 is fixedly installed on one side of the mounting shell 501. The telescopic end of the placement cylinder 506 passes through the mounting shell 501 and is fixedly connected to the moving plate 504. By placing the pressure cylinder 506 to drive the moving plate 504 to move, the linkage plate 505 drives the clamp 502 to be subjected to force, so that the clamp 502 can clamp and release.

[0042] Working principle: In use, the user first installs the equipment on the die-casting machine, allowing the upper slide pin 603 to pass through the upper end of the fixed mold and the lower slide insert 605 to pass through the lower end of the fixed mold. Simultaneously, the moving mold insert 1 606 and the moving mold insert 2 607 pass through one side of the moving mold, ensuring the fixed and moving molds are parallel. At this point, the fixed mold is stationary. Next, remove the mounting shell 501 from the back of the mounting base 2 and install it on the robotic arm. The robotic arm then moves the mounting shell 501 closer to the machine and places it aside. The die-cast aluminum tube body 7 is formed, and the placement cylinder 506 is activated, causing the placement cylinder 506 to drive the moving plate 504 to approach the clamp 502. This causes the moving plate 504 to exert force on the clamp 502 via the linkage plate 505, opening the clamp 502. As the clamp approaches the aluminum tube body 7, the moving plate 504 resets, allowing the clamp 502 to clamp the aluminum tube body 7. With the assistance of the robotic arm, the aluminum tube body 7 is placed at the upper opening of the lower slider insert 605. At this point, the robotic arm rotates the aluminum tube body 7, allowing the aluminum... The tube body 7 contacts the upper slider spring pin 603 at an angle, causing the spring on the upper slider spring pin 603 to compress. When the upper end of the aluminum tube body 7 is in full contact with the upper slider spring pin 603, the spring pushes the upper slider spring pin 603 downward, thereby locking the aluminum tube body 7 in place and thus limiting the upper and lower positions of the aluminum tube body 7. Immediately afterwards, the clamping cylinder 612 is activated, causing the clamping cylinder 612 to move the left slider 601 and the right slider 602 closer to each other during the movement. During the process, the die-casting machine contacts the outer surface of the aluminum tube body 7 and limits its left and right movement. Next, the drive cylinder 610 and the positioning cylinder 611 are activated, which drive the moving mold insert 606 and the moving mold insert 607 to approach the aluminum tube body 7 through the connecting plate 608 and the drive plate 609, respectively, thereby positioning the aluminum tube body 7 front and back. Finally, the moving and fixed molds of the die-casting machine are closed to cover the aluminum tube body 7, and after covering, liquid metal is poured into the mold to complete the die-casting of the mold.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
