[0004] Furthermore, a sliding block is movably arranged on the rear template, and the rear template is connected with the pulling block via a spring.

[0005] Furthermore, the sliding block is connected to the pulling block via a slot.

[0006] Furthermore, the ejector pin is movably connected to the product.

[0007] Furthermore, the fixed mold plate, the fixed mold back plate, and the fixed mold fixing plate are connected in sequence.

[0008] Furthermore, the rear mold plate is connected to the movable mold fixing plate.

[0009] The beneficial effects of the utility model are as follows: the utility model simplifies the mold structure, reduces the volume of the plastic mold, saves the mold cost, and achieves the purpose of completing the undercut and ejection mold on the product at a low cost and with a simplified structure.

DETAILED DESCRIPTION

[0016] A plastic mold product strong release structure, such as Figure 1-Figure 5 As shown, it includes a molding machine, a fixed mold plate 3, and a rear mold plate 13. The molding machine is connected to the fixed mold plate 3. A fixed inclined guide column 5 is arranged on the fixed mold plate 3. A slider 6 and a pull block 7 are arranged on the rear mold plate 13. An inclined channel 51 plugged with the inclined guide column 5 is arranged on the slider 6. The slider 6 is connected to the pull block 7. A dynamic mold core 12 is fixedly arranged on the rear mold plate 13. A product 4 is arranged on the dynamic mold core 12. The pull block 7 is connected to the product 4. An oil cylinder 8 is fixedly arranged on the rear mold plate 13. The oil cylinder 8 is connected to an ejector plate 9. An ejector 11 is arranged on the ejector plate 9. The ejector 11 is connected to the product 4.

[0017] Wherein, a sliding block 6 is movably arranged on the rear template 13, and the rear template 13 is connected with the pulling block 7 through a spring.

[0018] The sliding block 6 is connected to the pulling block 7 via a slot 61 .

[0019] The ejector pin 11 is movably connected to the product 4 .

[0020] Wherein, the fixed mold plate 3, the fixed mold back plate 2, and the fixed mold fixing plate 1 are connected in sequence.

[0021] Wherein, the rear mold plate 13 is connected to the movable mold fixing plate 10 .

[0022] like Figure 1 As shown in the figure, the two sides of the product are inverted, and the product cannot be ejected smoothly when the mold is ejected; Figure 2 A pull block 7 is made at the undercut of the product. After the mold is opened, the slider 6 drives the pull block 7 to pull the product 4 to both sides, and then the oil cylinder 8 provides power to pull the ejector 11 on the ejector plate 9 to eject the product 4, completing the undercut removal action.

[0023] like Figure 3As shown, when the mold is opened, the molding machine provides power, and the inclined guide column 5 on the fixed mold plate 3 drives the slider 6 to slide to both sides. During the sliding process of the slider 6, the pull block 7 is engaged by the slot on the slider, and drives the pull block 7 to slide to the outside of the product. The pull block 7 pulls the two sides of the product 4, so that the product is buckled out of the moving model core 12, and then the oil cylinder 8 outputs power to drive the ejector plate 9, and the ejector 11 on the ejector plate 9 ejects the product 4 to complete demoulding.

[0024] When closing the mold, the oil cylinder 8 provides power to drive the ejector plate 9 to reset the ejector 11, and then the molding machine provides power to push the fixed template 3, so that the inclined guide column 5 is pressed into the slider 6, and the slider 6 pushes the pull block 7 to reset, completing the mold closing.

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and concept of the utility model within the technical scope disclosed by the utility model, which should be covered by the protection scope of the utility model.
