Title of Invention	AN IMPROVED DEVICE FOR EJECTING OF PATTERNS FROM CAVITY OF DIE OF AN INJECTION PRESS.
Abstract	An improved device (10) for ejcting of patterns from cavity of die of an injection press has a cylindrical bod^(i2) defining a passage (14) with both ends open and the top open end (18) being convergent. An ejeator pin(20) is provided within the said passage of the cylindrical body0 The top end of the ejector pin is in contact with th$ convergent, top end of the cylindrical'body end seals the passage. Sealing rneans, J22) made of 6oft and mould able material secured to the bottom end of the efdtor pin seals the passage within the cylindrical body. A spring (26) loaded guide pin (24) is verfticaily provided below the sealing means whi^h Is in Alignment with the ejector pin. A cap/bush (28) is secured at the bottom open end (16) of the passage of the cylindrial body. The free end of the guide pin projects out from the cap/bush.

Abstract

An improved device (10) for ejcting of patterns from cavity of die of an injection press has a cylindrical bod^(i2) defining a passage (14) with both ends open and the top open end (18) being convergent. An ejeator pin(20) is provided within the said passage of the cylindrical body0 The top end of the ejector pin is in contact with th$ convergent, top end of the cylindrical'body end seals the passage. Sealing rneans, J22) made of 6oft and mould able material secured to the bottom end of the efdtor pin seals the passage within the cylindrical body. A spring (26) loaded guide pin (24) is verfticaily provided below the sealing means whi^h Is in Alignment with the ejector pin. A cap/bush (28) is secured at the bottom open end (16) of the passage of the cylindrial body. The free end of the guide pin projects out from the cap/bush. Cap/bush also supports th^ spring (26) from below0 An air-inlet (32) located between the sealing me^ns and convergent-top open and allows pressurised air into the passage in the cylindrical bodye.
