Abstract
A blow molding device in which a preform is injection-molded, the injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10° C. or more lower than the glass transition temperature of the preform.
Claims14
A mold for temperature adjustment which is to be provided on a temperature adjustment station of a resin container manufacturing apparatus and which is capable of adjusting temperature of one or more bottomed hollow preforms at the same time, the resin container manufacturing apparatus at least including an injection molding station configured to injection-mold the preform, the temperature adjustment station configured to adjust a temperature of the injection-molded preform, a blow molding station configured to blow-mold the temperature-adjusted preform, and a neck mold configured to convey the preform to each of the molding stations,
- wherein the mold for temperature adjustment at least comprises:
- a plurality of temperature adjustment blocks aligned in an upper and lower direction;
- a centering ring provided on an upper portion of the temperature adjustment block located on the uppermost stage, and configured to come in contact with the neck mold;
- and
- a fixing plate disposed below the plurality of temperature adjustment blocks,
- the temperature adjustment blocks at least comprises:
- an accommodating portion configured to accommodate a body portion or a bottom portion of the preform;
- a flow path formed around the accommodating portion and in which a temperature adjustment medium is to flow;
- and
- a connection portion configured to be connected to the flow path and to flow or flow out the temperature adjustment medium, and
- an insulation structure is provided on a boundary between the plurality of temperature adjustment blocks, and
- wherein the plurality of temperature adjustment blocks are formed by a single temperature adjustment pot without the boundary at the accommodating portion.
