Document Type and Number:
WIPO Patent Application WO/2011/132220
Kind Code:
A1
Abstract:
Disclosed is an injection molding device provided with: a supply pipe that supplies a heat medium to a die; a discharge pipe that discharges the heat medium from the die; a die temperature regulator that adjusts the die temperature and to which the supply pipe and the discharge pipe are connected; and a discharge flow adjustment unit provided at a position on the upstream side of the die temperature regulator on the discharge pipe. The discharge flow adjustment unit comprises has a variable restrictor provided on the discharge pipe and which adjusts the flow volume of the heat medium, a discharge pipe variable restrictor bypass pipe which bypasses the variable restrictor, and a discharge pipe bypass open-close valve which changes the flow of the heat medium and is provided on the bypass pipe.
