[0034] See also Figure 1-4 The utility model provides a technical solution: a multi-stage linkage slider structure, comprising:

[0035] The first slider 1 is abutted against the side of the product 100 and is driven by the driving mechanism 2 to slide on the middle mold 3 of the mold. The side of the first slider 1 is provided with a first mounting hole 12 and a second mounting hole 13;

[0036] A second slider 4 is assembled in the first mounting hole 12, with its inner end docking with the first inlet 110 of the product 100;

[0037] The third slider 5 is slidably connected in the second mounting hole 13 and includes an upper slider 51, a guide column 52 and a lower slider 53. The upper slider 51 is connected to the linkage block 6 on the front mold of the mold. The guide column 52 is obliquely inserted into the first connecting hole 511 and the second connecting hole 531 of the upper slider 51 and the lower slider 53 and is positioned on the upper slider 51. The outer opposite surfaces of the upper slider 51 and the lower slider 53 are respectively provided with a first wedge surface 512 and a second wedge surface 532. A side-drawing slider 55 is provided on the inner side of the lower slider 53. The side-drawing slider 55 is connected to the second inlet 120 of the product 100. The lower slider 53 is slidably provided in the second mounting hole 13 along the axial direction of the second inlet 120.

[0038] Stepped guide blocks 31 are provided on both sides of the middle mold 3 , and the stepped side edges of the first sliding block 1 are slidably connected between the stepped guide blocks 31 .

[0039] The driving mechanism 2 includes a driving rod 21 whose end is clamped on the bayonet 11 of the first slider 1 and a cylinder 22 driving the driving rod 21 . The cylinder 22 is positioned on the mounting frame 32 of the middle mold 3 .

[0040] The opening direction of the second mounting hole 13 is inclined to the opening direction of the first mounting hole 12 .

[0041] An extension plate 533 is provided inside the lower sliding seat 53 , and the side-drawing slider 55 is installed in the positioning groove 534 of the extension plate 533 .

[0042] A guide plate 54 is installed in the second mounting hole 13 , and the lower sliding seat 53 is slidably disposed on the guide plate 54 .

[0043] A wavy guide groove 541 is provided on the inner side of the guide plate 54 , and the protrusion on the side of the lower slide seat 53 is slidably disposed in the wavy guide groove 541 .

[0044] An elastic blocking block 551 is provided inside the side-drawing slider 55 .

[0045] The working principle of the multi-stage linkage slider structure of this embodiment includes the following: during mold demolding, the front mold moves away from the middle mold 3, driving the inlay pin to disengage from the axial assembly hole on the edge of the product 100. The linkage block 6 simultaneously drives the upper slide 51 away from the lower slide 53. Guided by the guide column 52 and the wedge surface, the lower slide 53 is pushed outward, and the side-drawing slider 55 disengages from the second inlet 120 to achieve its demolding. During this period, the lower slide 53 is guided by the wavy guide groove 541 and cooperates with the elastic blocking block 551 to achieve low-resistance demolding. The oil cylinder 22 drives the first slider 1 to disengage from the product 100 and simultaneously drives the second slider 4 to disengage from the first inlet 110, thereby achieving overall demolding. When the mold is closed, the first slider 1 and the second slider 4 are driven to move to the corresponding positions on the surface of the product 100 and the first inlet 110, respectively. The front mold is closed, and the guide column 52 engages the lower slide 53 and moves it inward to the position corresponding to the second inlet 120 to achieve mold closing.

[0046] In summary, due to the adoption of the above technical solution, the multi-stage linkage slider structure of this embodiment has the following beneficial effects compared with the prior art:

[0047] The utility model drives the first slider to move by an oil cylinder, and sets a third slider associated with the front mold and the first slider, thereby realizing core pulling and demoulding in different directions and toward the structure of the local area of ​​the product side, and segmented multi-stage linkage, realizing interference-free mold opening and closing operations, and improving the processing efficiency and quality of the product; during this period, the lower slide is guided by the wavy guide groove and cooperates with the elastic blocking block to realize low-resistance demoulding.
