Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): as shown in fig. 1 and 2, the novel ejector block structure comprises a B plate 1, a pair of injection molding bottom dies 2 which are symmetrically distributed and are nested with the B plate 1 are arranged on the B plate 1, and injection molding side pressing dies 4 which are fastened with the B plate 1 through screws are arranged on the injection molding bottom dies 2. The bottom plate 7 is arranged below the B plate 1, the ejector plate 5 is arranged between the bottom plate 7 and the B plate 1, the push plate 6 fastened with the ejector plate 5 is arranged between the ejector plate 5 and the bottom plate 7, and the double-section ejector block assembly 3 which penetrates through the push plate 6 in a sleeved mode and is in elastic contact with the bottom plate 7 is arranged in the injection molding shaping bottom die 2. The double-section ejector block component 3 comprises an ejector block 8, and an ejector rod 11 is arranged at the lower end of the ejector block 8. The lower end of the ejector rod 11 is provided with a fixed block 14, the fixed block 14 is provided with a fixed rod 13 which is sleeved with the ejector rod 11, a guide sleeve 10 which is sleeved with the ejector rod 11 is arranged between the ejector block 8 and the fixed rod 13, and a guide block 12 which is movably sleeved with the ejector rod 11 is arranged between the guide sleeve 10 and the fixed rod 13. A clamp spring 9 which is clamped and embedded with the top block 8 and is in limiting sleeve joint with the top block 8 is arranged between the guide sleeve 10 and the top block 8. A pair of symmetrically distributed springs 16 is arranged between the fixed block 14 and the bottom plate 7. A guide rod 15 which is in an integrated vertical structure with the fixed block 14 and is sleeved with the spring 16 is arranged in the spring 16.

The guide rod 13 is fixed on the fixed block 14 and then is arranged in a corresponding hole of the ejector plate 5, and the ejector rod 11 is positioned with the fixed rod 13.
