Abstract

PURPOSE:To enable forming of a core without any influence of outline shape of core surface and size by fitting machine inserting part forming member (core) for watch case with screws from back face of the core in an insert type die. CONSTITUTION:Cavity 6, core support 2 and ejector pins 7 are engaged with a cavity plate 8 in the die for die casting. The core 1 cutting the screw on the back face is fitted with the screw from the back face of the core support 2. As the guide groove 4 is arranged at front side in the core support 2 positioning of the core can be easily executed. By such construction, even if the core is small size, there is no problem, which remained thickness of the core is eliminated and molten metal is penetrated into spot facing part. By this method, as the forming of the core can be executed without any influence of the outline shape of the core surface and the size, the extremely small watch case can be produced.

However, in the above-mentioned conventional technology, when fixing the core, for example, when fixing the core 1 for an extremely small watch case to the core support 2, since the core 1 is small, if the core is counterbore 3 from the front side, the remaining thickness is 1.
The problem is that a is missing, making it impossible to manufacture extremely small watch cases.

FIG. 3 is a partial sectional view showing another embodiment of the present invention,
A guide pin 5 is provided in the core support 2 in place of the guide groove 4 shown in FIG. 2, and a hole in which the guide pin 5 is engaged is formed in the core 1 so that the core 1 is positioned.
