Integrated molding system for paraffin ball sealing center core

The invention discloses an integrated molding system for a paraffin ball sealing center core. The integrated molding system comprises an inner ball cover and an outer ball cover, wherein the outer ball cover is a ball body cover with a ball body cavity inside; an open round hole is formed in one end of the outer ball cover; a molten paraffin flow tube is assembled on the inner wall of the round hole of the outer ball cover through threads; the diameter of the inner ball cover is the same as that of the round hole of the outer ball cover; a core material guide pipe which is communicated with an inner chamber of the inner ball cover is processed at the end, opposite to the round hole of the outer ball cover, of the inner ball cover; and a through hole out of which the core material guide pipe extends is formed in the end, opposite to the round hole, of the outer ball cover. By virtue of the technical scheme, through sleeving and wrapping of the inner ball cover and the outer ball cover, overall paraffin sealing and wrapping are realized by injection at different orders; and the influences of temperature and air are avoided.
