Abstract
PURPOSE:To prevent generation of cold slug and whiting and obtain the container of excellent transparence by inserting a heating and cooling layer element utilizing Peltier effect at the junction of semiconductors between the nozzle of the injection molding machine and the mold cavity. CONSTITUTION:Parison 3 is formed by injection molding between a cavity mold 1 provided with a cooling water passage 6 and a core mold 2. The heating and cooling layer element 10 is arranged at the cavity bottom mold part 7, surrounding the gate part 9 and its cooling surface 10a faces to the cavity side and its heating surface 10b faces to the injection molding machine side or the runner part B side. This divides the mold part 7 into the low temperature part 7a and the high temperature part 7b. The heating and cooling layer element 10 arranges the plural N type semiconductors 21 and P type semiconductors 23 alternately on a plane and are connected in series by the conductor 23 at its both sides, the temperature difference of 70 deg.C between the surfaces 10b and 10a can be given.
