Title:
中空成形品の成形方法および製造装置
Document Type and Number:
Japanese Patent JP4527159
Kind Code:
B2
Abstract:
A method of molding a hollow molded article, a hollow molded article, and an apparatus for manufacturing the same are provided to secure high molding accuracy and sufficient adhesion strength by using a contact-section of a pair of half-molded products through molding pressure. A method of molding a hollow molded article comprises the steps of: molding first and second half-molded products with moving mold(3) and fixed mold(1) to have a contact intersection plane; allowing the moving mold to slide in a state that the second half-molded product exists; matching each contact intersection plane; inserting a heater(41) between the contact intersections, wherein the heater is made of a halogen heater or a carbon heater; separating the heater after molding the contact intersection plane by the heater; and fusing the intersection planes by closing the moving and fixed molds.
