It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] 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.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a split-type aluminum alloy die-casting mold assembly device, including a die-casting table 1, a connecting block 2 sleeved on the top of the die-casting table 1, an upper mold 6 fixedly connected to the bottom of the connecting block 2, a first combined mold 3 and a second combined mold 4 slidably connected to the upper surface of the die-casting table 1, the first combined mold 3 and the second combined mold 4 being spliced ​​together, a bending rod 5 being detachably connected to one end of the first combined mold 3 and one end of the second combined mold 4 by bolts, a first electric cylinder 11 being fixedly installed inside the die-casting table 1, one end of the piston rod of the first electric cylinder 11 being fixedly connected to the bending rod 5, a limiting block 7 being movably installed on the upper surface of the die-casting table 1, the limiting block 7 being located on both sides of the first combined mold 3, an extension piece 8 being fixedly installed on both sides of the first combined mold 3 and both sides of the second combined mold 4, the limiting block 7 being pressed onto the upper surface of the extension piece 8, a strip hole 9 being opened inside the limiting block 7, a limiting screw 10 being threadedly connected to the upper surface of the die-casting table 1, the limiting screw 10 being located inside the strip hole 9.

[0024] The specific settings and functions of this embodiment are described below. In use, the connecting block 2 is used to connect with an external power mechanism. In use, the first combined mold 3 and the second combined mold 4 are spliced ​​together to form part of the die-casting mold cavity. Then, the aluminum alloy is placed on top of the first combined mold 3 and the second combined mold 4. The connecting block 2 drives the upper mold 6 to move downward to complete the die-casting of the aluminum alloy. After long-term use, when the first combined mold 3 and the second combined mold 4 are worn, the first electric cylinder 11 is started first. The bending rod 5 is used to take the first combined mold 3 and the second combined mold 4 away from the die-casting table 1. Then, the limiting screw 10 is moved upward a little distance to release the limiting block 7. The presence of the strip hole 9 provides the limiting block 7 with a space for movement, so as to facilitate the removal of the first combined mold 3 and the second combined mold 4. The edges of the first combined mold 3 and the second combined mold 4 are provided with extension pieces 8 for contacting the limiting block 7. The limiting block 7 can determine the movement path of the first combined mold 3 and the second combined mold 4. The side of the limiting block 7 is provided with a serrated groove to accommodate extension pieces 8 of different thicknesses.

[0025] Example 2: Figure 5 As shown, a docking block 12 is fixedly installed at the other end of the first combined mold 3. The docking block 12 is inserted into the interior of the second combined mold 4. The interior of the second combined mold 4 is provided with a receiving groove 13. The interior of the die-casting table 1 is fixedly installed with a second electric cylinder 15. The second electric cylinder 15 is located below the second combined mold 4. The interior of the docking block 12 is provided with a through hole 14.

[0026] The overall effect of this embodiment is that the docking block 12 is used to connect the first combined mold 3 and the second combined mold 4. When the first combined mold 3 and the second combined mold 4 are assembled, the docking block 12 will be inserted into the receiving groove 13. Then the second electric cylinder 15 is activated, so that the piston rod of the second electric cylinder 15 is inserted into the through hole 14 in the docking block 12, thereby completing the limiting of the first combined mold 3 and the second combined mold 4 to ensure the stability of the first combined mold 3 and the second combined mold 4.

[0027] The usage method and working principle of this device: Preparation stage: By setting the position of the limit block 7, the sliding path of the first combined mold 3 and the second combined mold 4 is determined. At the same time, the connecting block 2 is securely connected to the external power mechanism.

[0028] Mold assembly: Start the first electric cylinder 11 to retract its piston rod, which pushes the connected bending rod 5. The bending rod 5 drives the first combined mold 3 and the second combined mold 4 to slide on the upper surface of the die-casting table 1 until the mating block 12 of the first combined mold 3 is accurately inserted into the receiving groove 13 of the second combined mold 4, thus completing the mold assembly. Then, start the second electric cylinder 15 to insert its piston rod into the through hole 14 of the mating block 12, further limiting the assembled mold and enhancing its stability.

[0029] Die casting operation: The aluminum alloy material is placed on top of the pre-assembled first mold 3 and second mold 4. An external power mechanism drives the connecting block 2, which in turn moves the upper mold 6 downward to die cast the aluminum alloy.

[0030] Mold Separation and Maintenance: When the first combined mold 3 and the second combined mold 4 wear out after long-term use, firstly start the first electric cylinder 11 to extend the piston rod, drive the bending rod 5, and then take the first combined mold 3 and the second combined mold 4 away from the die-casting table 1. Then move the limit screw 10 upward to release the limit block 7. Utilize the movable space provided by the strip hole 9 to easily remove the first combined mold 3 and the second combined mold 4 for repair or replacement.

[0031] 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.
