Abstract

A resin molding method according to the present invention is a resin molding method that fills a space between an insertion hole provided in a workpiece and a member to be fixed inserted into the insertion hole with resin, the method comprising: injecting a first tablet formed of thermosetting resin having a first temperature into a position of a pot far from the workpiece, the pot pouring the resin into the workpiece and being provided in a molding die, injecting a second tablet formed of thermosetting resin having a second temperature higher than the first temperature into a position of the pot close to the workpiece; pouring the thermosetting resin into the insertion hole of the workpiece in an order of the second tablet and the first tablet by a plunger that slides in the pot.

Claims (7)

1. A resin molding method that fills a space between an insertion hole provided in a workpiece and a member to be fixed inserted into the insertion hole with resin, the method comprising:

injecting a first tablet formed of thermosetting resin preheated to a first temperature into a position of a pot far from the workpiece, the pot pouring the resin into the workpiece and being provided in a molding die,

injecting a second tablet formed of thermosetting resin preheated to a second temperature higher than the first temperature into a position of the pot closer to the workpiece than the position at which the first tablet is injected; wherein:

the first tablet is softened less than the second tablet at the time when a part of the second tablet that is melted starts to be injected into the insertion hole,

the first tablet is softened as an injection process in which the second tablet is injected into the insertion hole advances, and

after the second tablet is injected into the insertion hole, the first tablet that has been softened starts to be injected into the insertion hole.

2. The resin molding method according to claim 1 , wherein a difference between the first temperature and the second temperature is 20° C. or higher.
