<P>PROBLEM TO BE SOLVED: To provide an injection mold of isomorphism-like multi-cavity especially suitable for manufacturing long and slender cylindrical or tubular molding. <P>SOLUTION: The injection mold includes: a sprue 2 to which molten resin to fill up a cavity 1 is made to flow in; a runner 3 which has a plurality of branch flow channels 30 which branch from the sprue 2; and a gate 4 which is communicated with the cavity 1 from an end 30a of the runner 3. The plurality of gates 4 are formed to the cavity 1. The mold is structured so that all distances from the sprue 2 to the plurality of gates 4 may be equal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
