The working principle is as follows: when the injection molding machine is actually used, during mold closing, after the injection molding is finished and the injection molding is finished, the mold is opened, the whole rear mold part carries a product and is separated from the front mold, because the shovel machine 23 on the small slide block 24 is locked on the front mold core 5, the small slide block 24 is opened under the action of the shovel machine 23 to the mold opening distance, when the mold is manufactured, the four-surface slide block splicing molding is needed, the product is transversely placed into the mold, the front mold core and the rear mold core are collided, the I-shaped appearance groove position is formed by adopting the slide block, the small slide block 24 is positioned by the M5 poking bead 22 after the mold is opened, the guiding is completed by matching the small slide block batten 37 with the small slide block 24 hanging platform, the middle of the product molding is a circular hole, the front mold core 5 and the rear mold core 6 are in a collision penetrating mode and are slidably fixed on the rear mold core 6 part, the shovel machine 23 and the small slide block 24 can pull the product from the front mold core 5, the rear mold core 6 is locked and positioned in the middle of the product, and the mold core 6 is positioned, and the mold opening phenomenon of the product can not occur when the small slide block 24 is finished. Meanwhile, when the mold is opened, the prepressing force is released by the prepressing spring 15 to push the reset rod 16 to pop out, so that the nylon shutter 17 can be opened in a delayed mode, and the nylon shutter 17 can be opened after the slider core 34 drives the product to be completely separated from the front mold core 5. When the nylon shutter 17 is opened, the product stripper plate 32 is pulled due to the locking force of the nylon shutter 17, at this moment, the injection-molded product 38 and the slider core 34 are tightly packed, and the oil cylinder 25 is not started yet, the slider seat 26, the slider core seat plate 30, the product stripper plate 32 and the slider core 34 are still in a close-fitting and positioning state on the core axis, at this moment, the product stripper plate 32 is pulled, and due to the action of the guide post 18, the product stripper plate 32 can only move on the axis of the guide post 18 by force, and the bottom surface of the product stripper plate 32;

the hanging table at the bottom surface simultaneously pulls the slide core seat plate 30 to synchronously open the mold S1 along the axis of the guide post 18 to be larger than the radial mold opening distance of the plastic part, the mold core 34 is synchronously and firmly fixed on the slide core seat plate 30 by the mold core fixing block 35 to synchronously displace, at this time, the slide seat 26 can only axially move along the shrinkage rod of the oil cylinder under the control of the large slide pressing strip 27, but the oil cylinder 25 is not started, so the slide seat 26 is still in a static state, but the slide seat 26 and the slide core seat plate 30 are connected by a slidable T-shaped guide rail, when the product stripper plate 32 is pulled, the slide core seat plate 30 and accessories fixed on the slide core seat plate 30 synchronously displace along the T-shaped guide rail S1, the limiting pull rod 19 forces the product stripper plate 32 to separate from the nylon shutter 17, the limiting plate 31 also limits the slide core seat plate 30 to continuously slide, at this time, the M10 stripper bead 29 also starts to act tightly to lock the product stripper plate 32 and the rear mold core 30, so as to lock the slide core 30 with the slide seat plate 26 and the slide core seat plate 18 to move along the axis, when the mold core is opened, at this time, the slide core is pulled, but the slide core is a slide core mold core is a cold mold runner, and a slide core runner part of a rear mold can be deformed in a slide mold. The driving oil cylinder 25 pulls the sliding block seat 26, the S distance is started, the sliding block seat 26 drives the sliding block core seat plate 30 and the sliding block core 34 by means of a T guide rail, the sliding block core 34 drives an injection molding product to synchronously move, the product stripper plate 32 is static due to the action of the guide post 18, the injection molding product is stripped from the sliding block core 34, the product freely falls under the condition of dead weight and completely leaves a mold cavity, the axial mold opening distance of the injection molding product exceeds the rear mold plate of the rear mold fixing plate 7 due to the fact that the axial mold opening distance of the injection molding product is too large, therefore, the sliding block bracket 28 is added to prolong the stroke of the sliding block seat 26, and the sliding block bracket 28 is positioned by the positioning pin 14 and fastened by a cup head screw.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
