Resin encapsulation device

Abstract

To suppress an increase in size of a resin sealing device.SOLUTION: A resin sealing device of the invention includes a first moving body, a second moving body, and a movable pin. The first moving body moves in a first direction that intersects a mold clamping direction, which is a direction in which a mold clamping is performed between the upper mold and the lower mold. The second moving body moves in the second direction, which is the mold clamping direction and approaches one of the upper mold and the lower mold, as the first moving body moves in the first direction. The movable pin is attached to the second moving body and moves in the second direction as the second moving body moves.SELECTED DRAWING: Figure 2

Claims
