Title
(EN) RESIN MOLDING DEVICE AND MANUFACTURING METHOD OF RESIN MOLDED ARTICLE
(JA) 樹脂成形装置及び樹脂成形品の製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a resin molding device and a manufacturing method of a resin molded article, capable of improving molding accuracy with a simple structure.

SOLUTION: A resin molding device is assembled with a mold C holding a molding object provided with a chip 13 on a substrate 11 and having a cavity MC to which a resin material Ta is supplied from a gate, a mold closing mechanism for mold closing the mold C, and a control part 6 for controlling the operation of the mold C and the mold closing mechanism, wherein the mold C includes a movable block 16 for squeezing at least a part of an inner channel of the cavity MC not provided with the chip 13 and a driving mechanism Ds for driving the movable block 16 with a fluid, and the control part 6 executes the control of changing a driving force of the driving mechanism Ds in molding the object with resin.
