As shown in fig. 10, the sliding distance of the sliding connection portion 623 on the limit strut 231 is B, the B value is greater than the moving distance required by the second guide rod 62 to withdraw the front mold slide 21, and the greater range is 1 to 2mm.
As shown in fig. 3, the segmented slider driving mechanism further includes a hot runner plate 30, a nozzle plate 40 and a guide post 50, where the front mold plate 20, the nozzle plate 40 and the hot runner plate 30 are sequentially slidably connected through the guide post 50, and the nozzle plate 40 and the hot runner plate 30 can slide on the guide post 50, so that the front mold plate 20, the nozzle plate 40 and the hot runner plate 30 can be separated from each other or folded with each other.
In this embodiment, the first guide rod 61 is fixed to the hot runner plate 30 and slides on the guide post 50 along the axial direction of the guide post 50 together with the hot runner plate 30, and a through hole through which the first guide rod 61 passes is required to be provided in the nozzle plate 40. After the mold is opened, since a certain separation distance is also provided between the nozzle plate 40 and the hot runner plate 30, the first guide rod 61 is fixed on the hot runner plate 30, so that the length of the first guide rod 61 between the front mold plate 20 and the nozzle plate 40 can be further reduced, and the risk of material blockage of the core pulling guide rod 60 can be further reduced. Wherein, after the die is opened, the length of the first guide rod 61 exceeding the nozzle plate 40 is within 50.0 m. Of course, in other embodiments, the first guide rod 61 may be fixed to the nozzle plate 40 and slid on the guide post 50 along the axial direction of the guide post 50 together with the nozzle plate 40, and by fixing the first guide rod 61 to the nozzle plate 40, the overall length of the first guide rod 61 may be reduced to reduce the risk of breakage of the first guide rod 61.
Further, as shown in fig. 4 to 6, the loose-core guide bar 60 includes a fixing base 64, the fixing base 64 is provided with a receiving hole for receiving the first guide bar 61, and an end portion of the first guide bar 61 protrudes from the receiving hole. In this embodiment, the fixing base 64 and the first guide rod 61 are fixed on the hot runner plate 30 together, and the fixing base 64 can increase the strength of the first guide rod 61 to reduce the risk of breakage of the first guide rod 61.
The present application also provides an injection molding machine comprising a rear mold plate 10 and a segmented slide drive mechanism as described above. As shown in fig. 3, in this embodiment, a front mold block 21 is provided on the front mold plate 20 of the injection molding machine, and therefore, the injection molding machine is provided with only one core back guide 60 that is engaged with the front mold block 21.
Fig. 11 is a schematic view of an injection molding machine in a mold closing state according to another embodiment of the present invention, as shown in fig. 11, in other embodiments, a plurality of front mold blocks 21 may be disposed on a front mold plate 20 of the injection molding machine, and each front mold block 21 has a core pulling guide bar 60 matched with the front mold block.
Specifically, during the mold closing process, the front mold plate 20, the gate plate 40, and the hot runner plate 30 are closed together, and the first guide bar 61 moves toward the front mold plate 20 together with the hot runner plate 30. When the first guide bar 61 moves to the preset position toward the front die plate 20 in the axial direction of the guide post 50, the first guide bar 61 slides against the second guide bar 62 in the axial direction of the guide post 50, and at the same time, the locking mechanism 63 locks the first guide bar 61 with the second guide bar 62, and the second guide bar 62 moves synchronously with the first guide bar 61 and drives the front die slide 21 to slide forward in the axial direction of the mandrel 22 until the mandrel 22 moves to the proper position;
during the mold opening process, the front mold plate 20, the nozzle plate 40 and the hot runner plate 30 are separated from each other, and the first guide rod 61 moves away from the front mold plate 20 together with the hot runner plate 30. Since the first guide bar 61 and the second guide bar 62 are in the interlocked locking state at the initial stage of die opening, the second guide bar 62 moves synchronously with the first guide bar 61 and drives the front die slide block 21 to slide reversely along the axial direction of the core shaft 22, i.e., drives the front die slide block 21 to slide along the core pulling direction. When the first guide bar 61 moves to the preset position, the lock mechanism 63 releases the mutual locking of the first guide bar 61 and the second guide bar 62 under the slope cooperation of the unlock stopper 633 and the lock slider 631, and the first guide bar 61 and the second guide bar 62 are separated from each other, at this time, the core pulling operation of the front mold slider 21 is completed.
