[0026] Reference Figures 1 to 5This utility model discloses a strong demolding structure for soft rubber products, including a front template (not shown in the figure), a rear template 1, an ejector plate 2, and a push rod 3 fixed to the ejector plate 2. The rear template 1 has an insert cavity 4, and the insert cavity 4 has a push plate 5 and a forming insert 6. The insert cavity 4 is a square groove, and the bottom of the square groove has a positioning groove, so that the push plate 5 can be installed and positioned through the square groove, and the bottom end of the forming insert 6 is located in the positioning groove, thereby realizing installation and positioning, facilitating assembly and processing. The push plate 5 has an insert hole 7, and the forming end of the forming insert 6 is located in the insert hole 7. The push plate 5 and the forming insert 6 have an undercut forming structure, and the undercut forming structure cooperates with the forming surface of the front template to form the forming cavity of the workpiece. The push rod 3 passes through the rear template 1 and is fixed to the push plate 5, so that the push plate 5 can be driven by the push rod 3 to disengage from the insert cavity 4.

[0027] As shown in the figure, specifically, the molding insert 6 of this application has two molding ends, which allows for the injection molding of two workpieces at once, improving efficiency. Correspondingly, the push plate 5 has two insert holes 7. The molding ends are cylindrical. The undercut molding structure includes a circular annular groove 8 on the molding end, a circular molding ring edge 9 on the hole wall of the insert hole 7, and a molding flange 10 on the molding ring edge 9. In this application, the molding flange 10 and the molding ring edge 9 are at a 90-degree angle to each other. The hole wall of the insert hole 7, the molding ring edge 9, and the molding flange 10 form an undercut groove 11. The bottom surface of the undercut groove 11 has a bottom groove 12. The molding flange 10 is embedded in the annular groove 8, and the wall of the annular groove 8 is embedded in the undercut groove 11 and tightly fitted with the bottom surface of the undercut groove 11. The bottom groove 12 and the gap between the forming edge 10 and the groove wall of the annular groove 8 form the cavity for forming the main body 17 of the workpiece. In the above structure, the main body 17 of the workpiece includes an undercut 13. The main body 17 and the undercut 13 are formed mainly by the mutual embedding of the annular groove 8 and the undercut groove 11. However, the demolding direction and the embedding direction are coincident. Therefore, although the undercut 13 of the workpiece is formed by the mutual embedding of the annular groove 8 and the undercut groove 11, the annular groove 8 and the undercut groove 11 can easily separate from each other when demolding, realizing the separation of the push plate 5 and the forming insert 6. Moreover, when the mold is opened, the push plate 5 can push the workpiece by contacting the forming ring edge 9 with the workpiece. Because the contact surface between the forming ring edge 9 and the workpiece is large, it is not easy to damage the workpiece.

[0028] As shown in the figure, the push plate 5 is provided with a square groove 14 that communicates with the insert hole 7, and a protrusion 15 is provided in the square groove 14. The end face of the protrusion 15 is in close contact with the forming surface. The gap between the square groove 14 and the forming surface constitutes the cavity for forming the workpiece's overlapping piece 16. The above structure can form the workpiece's overlapping piece 16 and the hole on the overlapping piece 16.

[0029] As shown in the figure, the rear template 1 is provided with a sliding hole 18, the push plate 5 is provided with a connecting hole and a through hole 19, one end of the push rod 3 is located in the connecting hole and the end surface of the push rod 3 is provided with a connecting screw hole, the connecting screw passes through the through hole 1 and is fixed with the connecting screw hole, the push rod 3 is fixed with the push plate 5 through the above structure, and assembly is facilitated.

[0030] As shown in the figure, the bottom surface of the rear template 1 is provided with an insert hole (not shown in the figure) and an insert (not shown in the figure) located in the insert hole, the sliding hole 18 is arranged on the insert, and the insert can be made of wear-resistant metal material, so that the service life of the mold is improved. Further comprising a bottom plate 20, the thimble plate 2 is provided with a through hole 2 (not shown in the figure), the other end of the push rod 3 is provided with an end cap located in the through hole 2, the bottom plate 20 is fixed with the thimble plate 2 and locks the push rod 3 in the thimble plate 2, and the above structure is convenient for manufacturing and assembly.

[0031] The above provides a kind of soft gel product's strong demolding structure provided by the embodiment of the utility model, has carried out detailed introduction, specific example has been applied in this paper to the principle and implementation mode of the utility model are described, the above embodiment is just for helping to understand the method of the utility model and its core idea;Meanwhile, for the general technical personnel of the field, according to the idea of the utility model, there will be changes in specific implementation mode and application range, and the above is described, the content of the specification should not be understood as the limitation of the utility model.
