As shown in fig. 1-2, an unilateral sliding block mechanism of an automobile plastic part mold comprises a movable mold 1 and an insert 2 detachably connected with the movable mold 1 and arranged at the center of the movable mold 1, wherein a main sliding block mechanism 3, an oblique sliding block mechanism 4 and a positioning sliding block mechanism 5 are arranged on one side of the upper surface of the movable mold 1, a locking part 21 is arranged on the corresponding side of the insert 2, the locking part 21 is provided with a main slide groove 22, an oblique slide groove 23 and a positioning slide groove 24, the main slide groove 22 and the positioning slide groove 24 are horizontally arranged, and the oblique slide groove 23 is obliquely arranged.

When the die is assembled, the main slide block mechanism 3, the inclined side slide block mechanism 4 and the positioning slide block mechanism 5 on the upper surface of the movable die 1 are provided with a main slide groove 22, an inclined side slide groove 23 and a positioning slide groove 24 through the locking part 21 of the insert 2 and are locked with the insert 2, so that the insert 2 is stably connected with the movable die 1, wherein the inclined side slide block mechanism 4 is arranged to be inclined, so that the phenomenon that the vertical stroke possibly causes clamping to influence the production efficiency can be effectively avoided. Meanwhile, in order to ensure the stability in the mold clamping state, only the oblique side slide block mechanism 4 is obliquely arranged.

Specifically, the main slide groove 22 is disposed at the center of the locking portion 21, the inclined slide groove 23 and the positioning slide groove 24 are disposed near two ends of the locking portion 21, respectively, and the inclined slide groove 23 is disposed obliquely to the main slide groove 22.

In order to reduce the space occupied by the stroke of the single-sided slider mechanism, the inclined side travel groove 23 is inclined toward the main travel groove 22.

More specifically, the insert 2 is provided with an insert convex portion 25 on one side of the locking portion 21 away from the moving die 1, the main slide block mechanism 3 is connected with the insert convex portion 25, and the main slide block mechanism 3 is further provided with two main slide block inserts 31 detachably connected with the insert convex portion 25. The arrangement of the insert convex part 25 ensures that the unilateral sliding block mechanism is more stably connected with the insert 2, and avoids possible strain or surface damage caused by direct stress of an injection molding part during mold opening and mold closing.

As shown in fig. 3, the main slider mechanism 3 includes a main slider seat 32, the two main slider inserts 31 are respectively disposed at two ends of the main slider seat 32 near one side of the insert convex portion 25, the two main slider inserts 31 are both provided with clamping lugs 33, and the upper surface of the insert convex portion 25 is provided with clamping lug grooves 251 corresponding to the two clamping lugs 33 one to one.
