Abstract

PURPOSE: To provide the subject unit wherein a member having a thermal conductivity more than that of the metal mold is inserted into a metal mold, and solidification of the resin within the gate after filling of the resin is rapidly progressed thereby to extremely reduce the gate remaining and to enable to make the thickness of the movement of a timepiece thinner.
CONSTITUTION: In order to rapidly solidify the resin within the gate 60 after the filling thereof, a columnar member 70 made of a beryllium-copper alloy or copper having a thermal conductivity more than that of the metal mold material is inserted in a metal mold 20 under a positional relationship corresponding to the gate. The cavity 40 is formed by a metal mold 10 in which a runner 50 is formed and a metal mold 20 in which the columnar member is inserted. In order to help the cooling of the columnar member, the end part thereof is exposed to the open air through an opening 31 formed at a movable side receiving plate 30. The gate part normally assumes temperature greater than that of other metal mold parts. However, when the cooling of the gate part is carried out rapidly, the gate cutting becomes excellent, and the gate remaining can be reduced.
