[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2As shown, a mold movable insert ejection mechanism, based on a silicone mold 2 and a movable insert 1, includes ejection assemblies respectively disposed on opposite sides of the silicone mold 2. Each ejection assembly includes an ejection arm 3, a Z-axis drive mechanism, and a Y-axis drive mechanism. The ejection arm 3 is disposed above the silicone mold 2, and its front end is connected to the movable insert 1. The Y-axis drive mechanism includes a first cylinder 21 and a Y-axis guide rail 5, which is disposed along the side of the silicone mold 2. The rear end of the ejection arm 3 is fitted onto the Y-axis guide rail 5, and the first cylinder 21 drives the ejection arm 3 to reciprocate along the Y-axis guide rail 5. A Z-axis drive mechanism is disposed at the bottom of the Y-axis guide rail 5, comprising a second cylinder 22 and a Z-axis guide rail 6. The second cylinder 22 drives the Y-axis guide rail 5 to reciprocate along the Z-axis direction. The Z-axis guide rail 6 is located on the outer wall of the silicone mold 2 and is disposed along the Z-axis direction of the silicone mold 2.

[0024] When ejecting the movable insert 1, the second cylinder 22 of the Z-axis drive mechanism drives the Y-axis guide rail 5 to rise, thereby causing the ejector arm 3 and the Y-axis guide rail 5 to rise. The ejector arm 3 drives the movable insert 1 to rise. Then, the first cylinder 21 of the Y-axis drive mechanism drives the ejector arm 3 to move along the Y-axis guide rail 5 to the outside of the workpiece, so that the movable insert can rise and separate to the outside. Then the product is taken out of the silicone mold 2.

[0025] like Figure 1 As shown, the ejector arm 3 includes two arms, each consisting of a connecting arm 13 and a drive arm 12 connected to each other. The drive arm 12 is arranged along the Y-guide rail 5. The front end of the connecting arm 13 is connected to the movable insert 1, which can raise the movable insert and separate it from the outside of the product, making it easier to remove the product.

[0026] like Figure 1 and Figure 2 As shown, it also includes a frame 14 and support columns 7. The frame 14 is arranged around the outer contour of the silicone mold 2, and the four corners of the frame 14 are respectively mounted on the support columns 7. The Y-guide rail 5 is installed on the frame 14. The Z-guide rail 6 is arranged between the two support columns 7. In this way, the ejection assembly is fitted to the silicone mold 2 through the frame 14 and support columns 7, which has a reasonable layout, small size, and low cost.

[0027] like Figure 2 As shown, a limiting plate 4 is provided on the frame 14, and the limiting plate 4 is located above the Y-guide rail 5. The limiting plate 4 is fixedly connected to the frame 14 by two guide posts 20. The guide posts 20 are arranged along the Z-axis and pass through the Y-guide rail 5, which reciprocates along the guide posts 20. When the second cylinder 22 of the Z-axis drive mechanism drives the Y-guide rail 5 to rise, the guide posts 20 play a guiding role, and the limiting plate 4 plays a limiting role.

[0028] This utility model discloses a mold movable insert ejection mechanism, which realizes the movable insert rising and separating outward through the ejection component, replacing the method of manually removing the movable insert, solving the problem of time-consuming and labor-intensive removal of movable inserts, and avoiding wear or damage caused by repeated manual removal of movable inserts, thereby improving production efficiency, saving labor, and reducing defect rate.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
