[0033] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.
[0034] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a mold core assembly / disassembly device for assembling and disassembling a mold core 200 on a machine head 100. The machine head 100 is provided with a first threaded hole 110 and a second threaded hole 120 located on both sides of the mold core 200. The mold core assembly / disassembly device includes a mounting plate 300, a mold core fixing assembly 400, a first support rod 500, and a second support rod 600.
[0035] The mounting plate 300 is provided with a third threaded hole 310, a fourth threaded hole 320 and a fifth threaded hole 330 at intervals. The mounting plate 300 can be made of metal material to have sufficient strength and rigidity to withstand the forces generated during the assembly and disassembly of the mold core 200.
[0036] The mold core fixing assembly 400 includes a fixing sleeve 410 and a handle 420. The fixing sleeve 410 is used to fit onto the mold core 200, and its inner diameter is slightly larger than the outer diameter of the mold core 200 to ensure that the fixing sleeve 410 can be securely fitted onto the mold core 200. The handle 420 is threadedly connected to a third threaded hole 310, with one end of the handle 420 passing through the third threaded hole 310 and connecting to the fixing sleeve 410. The operator can easily fit the fixing sleeve 410 onto the mold core 200 by rotating the handle 420, thereby fixing the mold core 200. During assembly and disassembly, the operator only needs to operate the handle 420 to complete the fixing and disassembly of the mold core 200, without the need for complex tools or cumbersome operating procedures, greatly improving the convenience of operation.
[0037] The first support rod 500 is threadedly connected to the first threaded hole 110 and the fourth threaded hole 320; the second support rod 600 is threadedly connected to the second threaded hole 120 and the fifth threaded hole 330. By setting the mounting plate 300 and the first support rod 500 and the second support rod 600 threadedly connected to the mounting plate 300, the first support rod 500 and the second support rod 600 are respectively threadedly connected to the first threaded hole 110 and the second threaded hole 120 on the machine head 100, forming a stable three-point support structure, effectively preventing slippage during disassembly and assembly. At the same time, the fixing sleeve 410 in the mold core fixing assembly 400 is firmly fitted onto the mold core 200, and is connected to the third threaded hole 310 of the mounting plate 300 through the handle 420, ensuring that the mold core 200 and the fixing sleeve 410 will not separate during operation, so that the mold core 200 and the fixing sleeve 410 can only move forward and backward in a predetermined direction without radial displacement, making it convenient for operators to stably remove or install the mold core 200, greatly improving work efficiency.
[0038] In one embodiment, the mounting plate 300 extends along a first direction X, and a third threaded hole 310, a fourth threaded hole 320, and a fifth threaded hole 330 are spaced apart along the first direction X; the first support rod 500 and the second support rod 600 both extend along a second direction Y, which is perpendicular to the first direction X. When assembling or disassembling the mold core 200, the force can be distributed more evenly on the mounting plate 300 and the first and second support rods 500 and 600. For example, when an external force is applied during mold core assembly or disassembly, the spaced fourth threaded hole 320 and fifth threaded hole 330 on the mounting plate 300 can distribute the force to the first and second support rods 500 and 600, giving the fixing sleeve 410 multiple support points along the first direction X. The head 100, the first support rod 500, the second support rod 600 and the mounting plate 300 form a frame-like structure. When subjected to tension, pressure and torque during the mold core assembly and disassembly process, this frame structure can better resist deformation and improve the overall strength of the mold core assembly and disassembly device, so as to achieve the purpose of stable and quick removal and assembly of the mold core 200.
[0039] The handle 420 includes a first connecting rod 421 and a second connecting rod 422. The first connecting rod 421 extends along a first direction X, and the second connecting rod 422 extends along a second direction Y. The second connecting rod 422 is threadedly connected to a third threaded hole 310. One end of the second connecting rod 422 is connected to the first connecting rod 421, and the other end is connected to a fixed sleeve 410. The handle 420 consists of the first connecting rod 421 extending along the first direction X and the second connecting rod 422 extending along the second direction Y. The first connecting rod 421 is for the operator to grip, and the second connecting rod 422 serves as a connector between the first connecting rod 421 and the fixed sleeve 410. The second connecting rod 422 is threadedly engaged with the third threaded hole 310 on the mounting plate 300. By rotating the first connecting rod 421, the first connecting rod 421 and the second connecting rod 422 rotate synchronously, thereby driving the fixed sleeve 410 to move along the second direction Y, realizing the assembly and disassembly of the mold core 200.
[0040] In this design, the length of the first connecting rod 421 is greater than the distance between the fourth threaded hole 320 and the fifth threaded hole 330. During the assembly and disassembly of the mold core, the first support rod 500 and the second support rod 600 are connected to the fourth threaded hole 320 and the fifth threaded hole 330, respectively, forming the support structure of the device. The greater length of the first connecting rod 421 provides ample operating margin for the operator, allowing them to hold the first connecting rod 421 with both hands. The longer first connecting rod 421 also increases the lever arm, thus saving effort.
[0041] The fixed sleeve 410 is provided with a receiving groove 411. A first locking block 412 and a second locking block 413 protrude from the groove wall at the end of the receiving groove 411 away from the second connecting rod 422. The first locking block 412 and the second locking block 413 are symmetrically arranged. The receiving groove 411 provides a specific placement space for the mold core 200, allowing the mold core 200 to be precisely embedded within it, preventing the mold core 200 from shaking during assembly and disassembly. The symmetrically arranged first locking block 412 and second locking block 413 protrude from the groove wall, forming a limiting structure for the mold core 200. This structure can lock the locking portion 210 (such as a protrusion, groove, or other mating structure) on the outer peripheral wall of the mold core 200, further restricting the displacement of the mold core 200 within the receiving groove 411, effectively preventing the mold core 200 from shifting or falling off during assembly and disassembly. When the symmetrical first locking block 412 and second locking block 413 contact the mold core 200, the clamping force on the mold core 200 is more evenly distributed.
[0042] In one embodiment, a first locking plane 412a is provided on the first locking block 412, and a second locking plane 413a is provided on the second locking block 413. Both the first locking plane 412a and the second locking plane 413a are parallel to the second direction Y, and the distance between the first locking plane 412a and the second locking plane 413a is less than the inner diameter of the mounting groove. Specifically, since both the first locking plane 412a and the second locking plane 413a are parallel to the second direction Y, when fixing the mold core 200, the first locking plane 412a and the second locking plane 413a can fit tightly with the corresponding planar structures on the mold core 200. When the mold core 200 is embedded in the receiving groove 411, the first locking plane 412a and the second locking plane 413a form a strong clamping force on the mold core 200 from both sides, using the flatness of the planes to provide a uniform and stable clamping force, effectively preventing the mold core 200 from loosening, shaking, or even slipping during assembly and disassembly.
[0043] Since the first locking plane 412a and the second locking plane 413a are parallel to the second direction Y and the distance between them is less than the inner diameter of the mounting groove, this design makes it difficult for the fixing sleeve 410 to detach from the mold core 200 after it is fitted onto the mold core 200.
[0044] Both the first support rod 500 and the second support rod 600 are threaded rods. Different sizes of mold cores 200 have different installation positions. The threaded structure allows adjustment of the extension length of the first support rod 500 and the second support rod 600 by rotating the threaded rod, and achieves a threaded connection with the mounting plate 300.
[0045] In one embodiment, in the first direction X, the first support rod 500 and the second support rod 600 are symmetrically arranged on both sides of the second connecting rod 422. The symmetrical structure of the first support rod 500 and the second support rod 600 ensures that the first support rod 500 and the second support rod 600 on both sides are subjected to uniform force when the mold core assembly / disassembly device bears the weight of the mold core 200 or the assembly / disassembly torque, making the operation process more stable.
[0046] The mold core assembly / disassembly device also includes a first fastener 710 and a second fastener 720. Both the first fastener 710 and the second fastener 720 are located between the mounting plate 300 and the first connecting rod 421. The first fastener 710 is threadedly connected to the first support rod 500, and the second fastener 720 is threadedly connected to the second support rod 600. The first fastener 710 and the second fastener 720 can be nuts. By adjusting the positions of the first fastener 710 and the second fastener 720, the distance between the mounting plate 300 and the machine head 100 can be controlled, thereby controlling the force and speed of assembling and disassembling the mold core 200.
[0047] The mold core assembly / disassembly device also includes a third fastener 730 and a fourth fastener 740. Both the third fastener 730 and the fourth fastener 740 are located on the side of the mounting plate 300 away from the first connecting rod 421. The third fastener 730 is threadedly connected to the first support rod 500, and the fourth fastener 740 is threadedly connected to the second support rod 600. The third fastener 730 and the fourth fastener 740 can also be nuts, which, in conjunction with the first fastener 710 and the second fastener 720, can fix the positions of the mounting plate 300, the first support rod 500, and the second support rod 600, preventing the mounting plate 300 from moving during assembly / disassembly.
[0048] The working principle of the mold core disassembly and assembly device provided in this application embodiment is as follows:
[0049] First, insert the first support rod 500 and the second support rod 600 into the first threaded hole 110 and the second threaded hole 120 on the machine head 100, respectively. Then, tighten the third fastener 730 and the fourth fastener 740 to fix the first support rod 500 and the second support rod 600 on the machine head 100, making them difficult to pull out. Next, put the fixing sleeve 410 on the mold core 200 that needs to be disassembled, so that the first locking block 412 and the second locking block 413 are locked on the mold core 200. Then, adjust the position of the first fastener 710 and the second fastener 720 to maintain an appropriate distance between the mounting plate 300 and the machine head 100. Finally, by rotating the first connecting rod 421, the mold core 200 can be moved along the second direction Y, thereby realizing the disassembly and assembly of the mold core 200.
