Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1-5, a large-angle oblique ejector mechanism of an ejector plate comprises a fixed template 1 and a movable template 2, a bottom plate 3 is arranged below the movable template, a bottom plate cushion block 4 is arranged on the bottom plate, the upper end surface of the bottom plate cushion block 4 is an oblique supporting surface, an oblique ejector plate 5 and an ejector panel 6 are sequentially arranged on the oblique supporting surface, an oblique ejector pin 7 is fixed on the ejector panel 6, and the oblique angle of the oblique ejector pin 7 is 43 degrees;
a supporting block 8 is fixed between the movable template and the bottom plate, a triangular groove 9 is formed in one side, close to the inclined thimble 7, of the supporting block 8, and when the thimble bottom plate 5 and the thimble panel 6 drive the inclined thimble 7 to eject in an inclined manner, the thimble bottom plate 5 and the thimble panel 6 move along the lower inclined surface direction of the triangular groove 9 without interfering with the supporting block 8; an inclined guide hole 10 is formed in the inclined surface of the triangular groove 9, and the inclined thimble 7 penetrates through the inclined guide hole 10 and extends into the movable template 2.
