[0023] By setting the fixed mold slider 14 between the movable mold slider 15 and the movable mold slider locking block 16, the fixed mold slider 14 can slide in the movable mold slider locking block 16, and the fixed mold slider 14 extends the front end into the cavity, and the rear end of the fixed mold slider 14 cooperates with the fixed mold slider bent pin 13, which is beneficial to ensure the sliding stability of the fixed mold slider 14. Therefore, the movable mold slider locking block 16 is set between the fixed mold slider 14 and the movable mold slider 15. This design effectively solves the problem of interference between the fixed mold slider 14 and the movable mold slider 15, and ensures the shape of the product, and solves the problem of shrinkage and hollowness caused by thick product meat.

[0024] In this embodiment, a fixed mold slider bent pin 13 is fixed to the lower end of the fixed mold taking-up plate 1, and the fixed mold slider bent pin 13 passes through the runner stripping plate 2 and the fixed mold plate 3 from top to bottom in sequence. A movable mold slider seat 17 is provided on the movable mold plate 4, and one end of the movable mold slider seat 17 is connected to the movable mold slider 15. A movable mold slider locking block (16) is installed on the right side of the lower end of the fixed mold plate (3), and a movable mold slider bent pin (18) is provided above the movable mold slider locking block (16). The fixed mold taking-up plate 1 is provided with a latch locker 12 A cavity is opened on the right side between the movable mold slider 15 and the fixed mold core 9, one end of the fixed mold slider 14 extends into the cavity, and the other end of the fixed mold slider 14 cooperates with the fixed mold slider bent pin 13, a matching hole is opened on the upper end of the fixed mold slider 14, the end of the fixed mold slider bent pin 13 is inserted into the matching hole, and a reverse locking surface is provided on the end of the fixed mold slider bent pin 13, and a groove is opened in the movable mold slider locking block 16, and the reverse locking surface of the fixed mold slider bent pin 13 cooperates with the groove of the movable mold slider locking block 16.

[0025] By fixing the fixed mold slider bent pin 13 on the fixed mold taking-up plate 1, the fixed mold slider bent pin 13 passes through the runner stripping plate 2 and the fixed mold plate 3, and then the fixed mold slider bent pin 13 is inserted into the matching hole on the fixed mold slider 14. Since a reverse locking surface is set on the fixed mold slider bent pin 13, the reverse locking surface cooperates with the groove in the movable mold slider locking block 16, which can better prevent the fixed mold slider bent pin 13 from deforming. In summary, an ingenious slider stacking design is adopted between the fixed mold slider 14 and the movable mold slider 15, which avoids peripheral auxiliary equipment such as oil cylinders and air cylinders, simplifies the mold structure, and reduces the production cost.

[0026] In this embodiment, the movable mold slider seat 17 has an inclined hole in the middle and an inclined surface, the movable mold slider bent pin 18 cooperates with the inclined hole, and the inclined surface on the movable mold slider seat 17 cooperates with the mold slider locking block 16.

[0029] By installing the latch of the latch mold locker 12 on the fixed mold taking plate 1, and installing the locking sleeve on the fixed mold plate 3 and the movable mold plate 4, the latch is inserted into the locking sleeve, which is beneficial to ensure that the fixed mold plate 3 and the movable mold plate 4 cannot be separated when the fixed mold slider 14 opens the mold.

[0030] In this embodiment, a limiting pull plate 11 is fixed between the fixed template 3 and the left side of the movable template 4 by screws.

[0031] Since the limiting pull plate 11 fixes the fixed mold plate 3 and the movable mold plate 4 by screws, it is beneficial to limit the mold opening distance between the fixed mold plate 3 and the movable mold plate 4.

[0032] Working principle:

[0033] When opening the mold, the runner stripper plate 2 and the fixed mold plate 3 are separated first, the runner is disconnected from the product, and the fixed mold slider bent pin 13 drives the fixed mold slider 14 to move, running along the tunnel between the movable mold slider 15 and the movable mold slider locking block 16, and disengaging from the cavity. As the mold opening continues, the fixed mold pick-up plate 1 and the runner stripper plate 2 are separated, the material handle is removed from the runner stripper plate 2, and the external manipulator takes out the material handle. When the mold is opened to the set position, the pin of the latch locker 12 is disengaged from the locking sleeve, the fixed mold plate 3 and the movable mold plate 4 are separated, and the movable mold slider bent pin 18 drives the movable mold slider seat 17 to move, so that the movable mold slider 14 is removed from the cavity. After the movable mold side is opened to the set distance, the mold opening action is completed, and the ejector bar of the external molding machine acts on the mold ejection system composed of the ejector plate 6 and the ejector bottom plate 7 to realize the ejection of the product from the cavity. The actions during mold closing and mold opening are opposite in sequence.
