Title:
MOLD FOR HIGH HEAT EFFICIENCY INJECTION MOLDING, AND INJECTION MOLDING METHOD
Document Type and Number:
Japanese Patent JP2013166314
Kind Code:
A
Abstract:
To provide a method of manufacturing a molded article with excellent quality and productivity by enabling heat exchange of a product transfer surface with high efficiency.
Highly-efficient heat exchange is made possible by including assist blocks which abut on a cavity block and a core block directly relating to heat conduction of filled resin, and increase a heat conduction area of mold temperature control. More preferably, a heat shield layer formed of a low-heat conductivity member and an air insulation layer are included in a fitting and abutting part between the cavity block and a mold base for supporting and fixing the core block.
