As shown in fig. 9, a channel 270 is provided on the mold foot 27, and the slide 21 is pushed by the push-pull element 24 through the channel 270 to the locked and unlocked position on the operating side or the non-operating side. Specifically, the slide plate 21 is pushed up to the position where the slide plate is locked by using the push-pull member 24 having a diameter of 8mm or less on the operation side or the non-operation side, and the slide platen is pushed out in the reverse direction when the mold is formed.

Specifically, when the ejector rod 10 and the ejector part 3 need to be connected, the sliding plate 21 is firstly located at the loose position, that is, the sliding plate 21 is located at the second position, so that the second through hole 222 is arranged corresponding to the locking part 12, then the ejector rod 10 is inserted into the ejector part 3 through the locking part 12 and the second through hole 222, then the push-pull piece 24 is inserted into the channel 270 on the operation side or the non-operation side of the injection mold 2, the sliding plate 21 is pushed to the first position along the first direction, so that the first through hole 220 is arranged corresponding to the locking part 12, and the sliding plate 21 is clamped with the ejector rod 10, so that the quick connection between the ejector part 3 and the ejector rod 10 is realized; when the ejector rod 10 and the ejection part 3 need to be detached, the push-pull piece 24 extends into the channel 270 on the other side of the injection mold 2, the sliding plate 21 is pushed to the second position from the first position along the first direction, so that the second through hole 222 is arranged corresponding to the ejector rod 10, the locking part 12 can move to the outside of the ejection part 3 from the second direction, the ejector rod 10 and the ejection part 3 are unlocked, and the ejector rod 10 and the ejection part 3 can be detached quickly.

The method comprises the following operation steps:

1. adjusting the mold 2 to a proper position of the injection molding machine, and aligning the positioning rings;

2. locking the pressing plate or locking the mold 2 by using a magnetic template;

3. opening the mold 2, extending the ejector rod 10 of the injection molding machine with the cup head structure into the mold 2, and slightly ejecting for a short distance;

4. the sliding plate 21 is pushed to a clamping position by using a round iron rod type push-pull piece 24 with the diameter of 8mm through a through hole 250 on the die leg 27, and the cup head of the mandril 10 is clamped;

5. when the mold is unloaded, the sliding plate 21 is pushed to the loose position from the other side by the push-pull piece 24, the ejector rod 10 of the injection molding machine retreats to be loosened, and the mold 2 is lifted away.

In the actual die changing process, the new structure is used, the ejector rod 10 does not need to be screwed or disassembled, the die 2 is assembled and disassembled in a normal die assembling mode without a strong return mechanism, the strong return mechanism operates the sliding plate 21 through the die outer pulling piece 24 to switch the clamping position and the releasing position, the assembling and disassembling operation is finished at one step, no break point exists, the operation is simple, time and labor are saved, and the time for locking the strong return ejector rod 10 is shortened to 1min from the original 15 min.

Further, as shown in fig. 11, in the actual use process, the push-pull member 24 can be locked on the sliding plate 21, so that the sliding plate 21 can be pushed and pulled more conveniently.

Furthermore, the oil cylinder driving sliding plate 21 is designed to replace a pushing and pulling piece 24 to push the sliding plate 21 manually, so that the purpose of automatic locking and forced returning is achieved, and a foundation is laid for automatic mold changing.

Further, as shown in fig. 12 and 13, in practical use, the slide plate 21 cannot be pushed left and right due to space limitation, and at this time, a vertical sliding manner may be adopted.
