[0006] As a preferred technical solution, the lower end of the buckle insert is provided with a guide rod, the upper end of the guide rod passes through a pin, the two ends of the pin are connected to the buckle insert, the middle part of the moving part is provided with a guide groove, the lower end of the guide rod is inserted into the guide groove and moves back and forth along the guide groove.

[0007] As a preferred technical solution, the front end of the fastening insert is formed with an upper connecting section, the front end of the moving part is formed with a lower connecting section, the upper connecting section and the lower connecting section are combined to form a connecting strip, and the connecting strip is inserted into the product.

[0008] As a preferred technical solution, the rear end of the stop block is formed with a rear limiting strip, and a gap is formed between the rear end of the fastening insert and the front end of the sliding body, and the rear limiting strip is inserted into the gap.

[0009] As a preferred technical solution, limit blocks are provided on both sides of the stop block, and the two limit blocks are respectively located on both sides of the fastening insert.

[0010] The beneficial effects of this utility model are as follows: It provides a sliding insert release structure, which uses a dovetail groove structure for inclined locking and demolding. During the movement of the sliding body, the structure that is locked into the undercut groove inside the product slides down and detaches from the product on its own. The sliding body and the mold opening are integrated, which ensures that products with complex structures can be demolded quickly. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 4 As shown, in this embodiment, a sliding insert release structure includes a sliding body 1, a locking insert 2, and a moving member 3. An arc-shaped surface 4 is formed on the upper front end of the locking insert 2, and the arc-shaped surface 4 is inserted upward into the undercut groove of the product 15. An inclined surface 5 is provided at the lower end of the locking insert 2, and a dovetail groove 6 is provided at the upper end of the moving member 3. The inclined surface 5 slides in the dovetail groove 6. A stop block 7 is provided at the upper end of the locking insert 2, and the stop block 7 presses against the upper rear end of the locking insert 2.

[0020] Specifically, the lower end of the snap-fit ​​insert 2 is provided with a guide rod 8, the upper end of the guide rod 8 passes through a pin 9, and both ends of the pin 9 are connected to the snap-fit ​​insert 2. The middle part of the moving part 3 is provided with a guide groove 10. The lower end of the guide rod 8 is inserted into the guide groove 10 and moves back and forth along the guide groove 10. The front end of the snap-fit ​​insert 2 is formed with an upper connecting section 11, and the front end of the moving part 3 is formed with a lower connecting section 12. The upper connecting section 11 and the lower connecting section 12 are combined to form a connecting strip, which is inserted into the product 15. The rear end of the stop block 7 is formed with a rear limiting strip 13. A gap is formed between the rear end of the snap-fit ​​insert 2 and the front end of the moving body 1. The rear limiting strip 13 is inserted into the gap. Limiting blocks 14 are provided on both sides of the stop block 7. The two limiting blocks 14 are respectively located on both sides of the snap-fit ​​insert 2.

[0021] When the slide is opened, the hydraulic cylinder drives the slide body 1 to move backward. The slide body 1 pulls the moving part 3 laterally backward. Under the combined action of the dovetail groove 6 limiting and the stop block 7 pressing down, the snap-fit ​​insert 2 moves vertically downward along the dovetail groove 6. The arc surface 4 moves smoothly downward from the undercut groove of the product 15 and gets out. At this time, as the moving part 3 continues to pull backward, the snap-fit ​​insert 2 also moves backward, thus successfully getting out of the product 15.

[0022] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
