Patent ID: 7985360

Claim:
A method of adjusting temperatures of a plurality of metal molds traveling in rotation and in one direction toward a plurality of stations and executing molding, the method comprising: selecting a predetermined station of said plurality of stations; selecting a predetermined metal mold of said plurality of metal molds; disposing a heat transfer member for transferring heat at an end of each of said plurality of metal molds; providing a plurality of temperature adjustment plates at said predetermined station of said plurality of stations, movably supporting the plurality of temperature adjustment plates with a support plate, wherein at least one of the plurality of temperature adjustment plates moves close to and away from another at least one of the plurality of temperature adjustment plates; adjusting a temperature of the temperature adjustment plates, with a temperature adjustment machine; halting said predetermined metal mold at said predetermined station; executing a heat exchange when an end of said heat transfer member comes into contact with a temperature adjustment plate while said predetermined metal mold is halted at said predetermined station; adjusting the temperature of said predetermined metal mold during said heat exchange; clamping a heat transfer plate with a plurality of the temperature adjustment plates, wherein said heat transfer member comprises a plurality of heat pipes, each of the plurality of heat pipes having the heat transfer plate at an end of the plurality of heat pipes, inserting a portion of the plurality of heat pipes at which said heat transfer plate is not disposed into said predetermined metal mold; and executing the heat exchange as said heat transfer plate is clamped by said temperature adjustment plates, wherein each of the plurality of heat pipes is disposed in parallel to another of the plurality of the heat pipes and being disposed in a direction perpendicular to a conveying direction of the predetermined metal mold, the heat transfer plate and said temperature adjustment plates are formed of a material having a high heat transfer rate, the heat transfer plate is separate from the predetermined metal mold, the heat transfer plate covers one end of the heat pipe which protrudes from the predetermined metal mold, and the heat transfer plate is disposed on a side face of the predetermined metal mold.
