referring to fig. 3 and 4, when the mold is in a mold-closing state, the female mold plate 1, the male mold plate 2 and the carrier plate 3 are abutted against each other, and the female mold plate 1 and the male mold plate 2 are locked together by a mold locking device. At this time, the insert of the slide block 4 extends into the cavity for forming the reverse buckle 1101 of the product 11, and the locking structure 6 is in a locking state to lock the male mold plate 2 and the carrier plate 3 together, so that the shifting block 5 cannot move, so that the position of the slide block 4 is fixed, and the structure is stable.
When the mold is opened, the mold is divided into a first stage, a second stage and a third stage.
Referring to fig. 5 and 7, fig. 5 is a schematic structural diagram of a slide ejecting structure applied to a mold and the mold is in a first stage of mold opening according to the present invention. Fig. 7 is a schematic diagram of another structure of the present invention, in which the slide ejecting structure is applied to the mold and the mold is at the first stage of mold opening. In the first stage, the mold locker is unlocked, the male mold plate 2 and the female mold plate 1 are separated first, and in the process, when the distance between the male mold plate 2 and the female mold plate 1 reaches a preset distance, the unlocking structure 7 unlocks the locking structure 6. The distance between the male template 2 and the female template 1 is not increased until the first boss 801 abuts against the bottom of the first counter bore 102.
Referring to fig. 8 and 9, fig. 8 is a schematic structural diagram of a slide ejecting structure applied to a mold and the mold is in a second stage of mold opening according to the present invention. Fig. 9 is a schematic diagram showing another structure of the slide withdrawing structure applied to the mold and the mold is at the second stage of mold opening. In the second stage, the male mold plate 2 and the carrier plate 3 start to separate, in the process, the carrier plate 3 drives the shifting block 5 to move downwards, the inclined part 501 of the shifting block 5 shifts the sliding block 4, the sliding block 4 slides in a direction away from the cavity, and finally the insert is withdrawn from the back-off 1101 of the product 11 formed in the cavity. The distance between the carrier plate 3 and the male die plate 2 does not become larger until the second boss 901 abuts against the bottom of the second counter bore 202.
In the third stage, when the shutter 10 is subjected to a pressure reaching its opening pressure, the male template 2 continues to separate from the female template 1. Finally, the ejector pin ejects the product 11.
The beneficial effects of the invention are as follows: when the mold is closed, the locking structure 6 locks the carrier plate 3 and the male mold plate 2, so that the position of the sliding block 4 is fixed, and the structure is stable; and fix the shifting block 5 on carrier plate 3, through the separation between carrier plate 3 and the public template 2 when the mould is opened for the shifting block 5 can stir the slider 4 that sets up on public template 2, is fit for the great condition of product 11 back-off volume.
It should be noted that the present invention is not limited to the above embodiments, and any simple modification, equivalent variation and modification of the above embodiments by those skilled in the art based on the technical solutions of the present invention fall within the scope of the present invention.
