DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In this embodiment, an automobile wheel hub mold frame that is easy to disassemble includes a mounting seat 1, a groove 2 is opened on the top of the mounting seat 1, and a mold frame assembly 3 is movably arranged inside the groove 2. Hydraulic telescopic rods 4 are fixedly installed at both ends of the top of the mounting seat 1, and connecting pieces 5 located on both sides of the mold frame assembly 3 are fixedly installed at the telescopic ends of the two hydraulic telescopic rods 4, and a disassembly mechanism 6 is arranged between the two connecting pieces 5 and the mold frame assembly 3.

[0021] The disassembly mechanism 6 includes an anti-slip knob 601, a bidirectional threaded rod 602, a movable block 603, a limit groove 604, a limit rod 605, a positioning rod 606 and a positioning groove 607. The upper sides of the two connecting parts 5 are each provided with an anti-slip knob 601, and the bottoms of the two anti-slip knobs 601 are each fixedly installed with a bidirectional threaded rod 602 extending into the interior of the connecting part 5, and both ends of the outer surfaces of the two bidirectional threaded rods 602 are threadedly connected with movable blocks 603, and two limit grooves 604 are provided on the inner walls of the two connecting parts 5, and one side of the four movable blocks 603 is fixedly installed with a limit rod 605, and the other side of the four movable blocks 603 is fixedly installed with a positioning rod 606, and positioning grooves 607 are provided on the left and right sides of the mold frame assembly 3.

[0022] The two connecting parts 5 have openings on the outer surfaces of the two positioning rods 606 on the opposite sides. When the bidirectional threaded rod 602 rotates, the two movable blocks 603 move under the limitation of the limiting groove 604 and the limiting rod 605. The two movable blocks 603 drive the two positioning rods 606 to move in relative or opposite directions inside the opening, so that the two positioning rods 606 can be stuck in or leave the inside of the positioning groove 607, thereby locking the mold frame assembly 3.

[0023] Guide grooves 7 are provided at both ends of the bottom of the groove 2, and guide wheels 8 are fixedly installed at the bottom of the two connecting parts 5 and are slidably installed with the guide grooves 7. By setting the guide grooves 7 and the guide wheels 8, it is convenient to stably support the movement of the connecting parts 5, thereby improving the reliability of the mold frame assembly 3 when moving.

[0024] The mold frame assembly 3 is composed of mold frame 1 and mold frame 2. A wheel molding cavity is opened between the opposite sides of mold frame 1 and mold frame 2. Two hydraulic telescopic rods 4 respectively drive mold frame 1 and mold frame 2 to move in opposite directions for demoulding operation. Both upper and lower ends of the left side of mold frame 2 are provided with docking ports 10, and both upper and lower ends of the right side of mold frame 1 are provided with docking columns 9. Under the action of docking columns 9 and docking ports 10, positioning during mold closing is facilitated to ensure accurate alignment of the mold.

[0025] When implementing, follow these steps:

[0026] 1) When the mold frame assembly 3 needs to be replaced, first turn the anti-slip knob 601, and the anti-slip knob 601 drives the bidirectional threaded rod 602 to rotate;

[0027] 2) Under the sliding cooperation between the limiting rod 605 and the limiting groove 604, the rotation of the bidirectional threaded rod 602 drives the two movable blocks 603 on its outer surface to move in opposite directions, and the two movable blocks 603 drive the two positioning rods 606 to move in opposite directions;

[0028] 3) Start the two hydraulic telescopic rods 4 to drive the two connecting parts 5 to move away from each other, and the two connecting parts 5 drive the guide wheels 8 at the bottom to slide stably inside the guide groove 7;

[0029] 4) Finally, as the two connecting members 5 move away from each other, the two positioning rods 606 are driven to withdraw from the interior of the positioning groove 607, and the mold frame assembly 3 can be removed and replaced with another mold frame assembly 3 to be used, and the anti-slip knob 601 can be rotated in the reverse direction according to the above process.

[0030] In summary, the easily disassembled automobile wheel hub mold frame is provided with two connecting parts 5, and a disassembly mechanism 6 is provided between the two connecting parts 5 and the mold frame assembly 3, so that the mold frame assembly 3 can be disassembled between the two connecting parts 5, thereby facilitating the maintenance or replacement of the mold frame assembly 3, and facilitating the replacement of the appropriate mold frame assembly 3 according to production requirements, thereby improving the practicality of the device.
