[0016] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] Combined with Figures 1 to 4As shown, this embodiment discloses a T-lock for a T-mold, including a PLC-controlled cylinder 7, a draw hook 12, a movable hook 8, a T-lock block 9, a spring 10 and a lock tongue 11, wherein the T-lock block 9 is provided with a draw hook slide groove, a movable hook slide groove and a lock tongue slide groove, the draw hook slide groove and the movable hook slide groove are parallel to each other, the lock tongue slide groove is perpendicular to the movable hook slide groove, the piston rod of the PLC-controlled cylinder 7 is connected to the movable hook 8, the lock tongue 11 is installed in the lock tongue slide groove on the T-lock block 9, and the lock tongue 11 can be Sliding in the lock tongue slide groove, a spring 10 is arranged between the lock tongue 11 and the T lock block 9, a first circular hole is arranged on the T lock block 9, and a second circular hole is arranged at one end of the lock tongue 11, one end of the spring 10 is arranged in the first circular hole, and the other end is arranged in the second circular hole, the movable hook 8 passes through the movable hook slide groove, the movable hook 8 passes through the lock tongue 11 and is slidably connected with the lock tongue 11, one end of the pull hook 12 is arranged in the pull hook slide groove, and when locked, the end of the lock tongue 11 is connected with the hook head of the pull hook 12.

[0018] The T-die comprises a first fixed die 1, a first movable die 2, a second fixed die 3, a second movable die 4, a first T-lock 5 and a second T-lock 6. The first movable die 2 is fixedly connected to the second fixed die 3. The first fixed die 1 is arranged on a side of the first movable die 2 away from the second fixed die 3. The second movable die 4 is arranged on a side of the second fixed die 3 away from the first movable die 2. One end of the draw hook of the first T-lock 5 is fixed on the first fixed die 1. The T-lock block 9 of the first T-lock 5 is fixed on the first movable die 2. The PLC-controlled cylinder 7 of the first T-lock 5 is fixed on the first movable die 2. One end of the draw hook 12 of the second T-lock 6 is fixed on the second movable die 4. The T-lock block 9 of the second T-lock 6 is fixed on the second fixed die 3. The PLC-controlled cylinder 7 of the second T-lock 6 is fixed on the first movable die 2.

[0019] The hook head of the pull hook 12 is provided with a chamfer, and one side of the end of the locking tongue 11 is provided with a corresponding chamfer. The hook head of the movable hook 8 is provided with chamfers on both sides, and the middle of the locking tongue 11 is provided with chamfers on both sides.

[0020] When the mold is in the closed state, the first parting surface and the second parting surface are respectively in a closed state. When the first movable mold 2 and the first fixed mold 1 of the first parting surface are closed for injection, the first parting surface is locked by the injection pressure of the injection molding machine. Under the action of the PLC-controlled cylinder 7 of the second T-lock 6, the second T-lock 6 is locked, and the first T-lock 5 is in an open state under the action of the PLC-controlled cylinder 7. Then the first parting surface is opened, and then the piece is taken out. Then the mold is closed, the first T-lock 5 is locked, the second T-lock 6 is opened, and then the second parting surface is opened, and then the piece is taken out, and the cycle is repeated.

[0021] When closing the mold, the chamfer of the hook head of the pull hook 12 contacts the chamfer of the end of the lock tongue 11, so that the lock tongue 11 is completely retracted into the lock tongue slot and the spring 10 is compressed. Then the hook head of the pull hook 12 passes through the pull hook slot, and the lock tongue 11 rebounds under the action of the spring 10, locking the pull hook 12. When opening the mold, the PLC controls the piston rod of the cylinder 7 to retract and drive the movable hook 8 to move toward the cylinder 7. The chamfer on the movable hook 8 contacts the chamfer on the outer side of the middle part of the lock tongue 11, so that the lock tongue 11 is completely retracted into the lock tongue slot and the spring 10 is compressed. At this time, the pull hook 12 is separated from the lock tongue 11. After separation, the PLC controls the cylinder 7 to push the movable hook 8 out until the chamfer of the movable hook 8 is separated from the chamfer of the lock tongue 11, and the lock tongue 11 rebounds under the action of the spring 10.

[0022] The utility model can realize two parting surfaces opening molds at different times, and cycle opening molds can save cooling time. The reciprocating motion of the cylinder is controlled by PLC to control the opening and closing of the movable hook, the draw hook and the lock tongue, so as to realize the cycle opening mold process, with simple structure and low manufacturing cost.

[0023] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
