At present, due to the installation and assembly requirements, more clamping hook structures can be designed on plastic products, and in order to form the clamping hook structures, an ejection device is arranged on a plastic mold to eject the clamping hook structures of the products. In some plastic products, the hook structure faces the inside of the product, and the inward hook structure is generally withdrawn by using a taper pin mechanism. The current angle pin mechanism has simple structure and is insufficient in the actual use process: on one hand, the existing angle pin mechanism has a small exit stroke and is only suitable for exiting a small-size hook structure. On the other hand, when the product is ejected out in the mold opening, in order to ensure that the clamping hook structure is easy to be separated from the angle pin mechanism, the clamping hook structure of the product generally needs artificial inclined design under the condition of meeting the assembly requirement, so that the angle pin mechanism is prevented from pulling the clamping hook structure to cause product scrapping when the mold opening is carried out.
In view of this, it is actually necessary to develop a slider ejection structure, which can solve the problems in the prior art that the inclined pin mechanism has a small exit stroke, and the hook structure is difficult to disengage, resulting in a high product reject ratio.

the bottom of the sliding block deflector rod is fixedly arranged on the third ejector plate, and the top of the sliding block deflector rod is of an inclined structure;
the bottom of the ejector pin is arranged on the second ejector plate, and the top of the ejector pin is used for ejecting a product;
and the top rod penetrates through the lower fixing plate, and the top of the top rod is fixedly connected to the bottom of the third ejector plate.
Optionally, the first ejector plate and the second ejector plate are fixedly connected together.
Optionally, the moving distance of the ejector rod ejecting the third ejector plate is greater than the height of the through hole in the slider seat.
Optionally, the slider ejection structure further includes a first strong elastic element disposed between the core plate and the first ejector plate.
Optionally, the slider ejection structure further includes a second strong elastic element disposed between the core plate and the third ejection plate.
According to the sliding block ejection structure, when the mold is opened, the female mold plate moves upwards and is separated from the male mold plate, the ejector rod pushes the third ejection plate to move upwards, and meanwhile, the sliding block deflector rod on the third ejection plate penetrates through the through hole of the sliding block seat, and the top of the sliding block deflector rod is of an inclined structure and drives the sliding block seat to move when moving, so that the sliding block enters the male mold plate and exits a product; and then, the ejector rod continues to push the third ejector plate to move upwards, and drives the third ejector plate to move upwards together after contacting the second ejector plate until the ejector pins on the second ejector plate eject the product, so that the die sinking is completed. According to the sliding block ejection structure, the sliding block insert is made to exit from a product through the relative sliding of the sliding block deflector rod and the sliding block seat, and the product is ejected out through the ejector pin finally, so that the operation time is saved, the production efficiency is improved, and the problem that the defective rate of the product is high due to the fact that the hook structure is difficult to disengage is solved.
