发明名称 INJECTED MOLD
摘要 PURPOSE:To enable pin terminals to hold the predetermined interval and the predetermined angle without generating wears on mandrels or the like by a method wherein the speed and pressure of mold clamping with respect to the pin terminals are changed by providing elastic mechanisms during the clamping of a mold. CONSTITUTION:Mandrels 220, to each of which pin terminals 2 are held, are slided outward of a mold with the push pins 116 of the mold 110 at the opening of the mold, while the mandrels 220 are slid toward cavity 114 sides by elastic ally engaging cams 105 with slide plates 118 and 205 through springs 125 at the molding. Because the mold clamping force is not directly applied to the mandrels 220, to each of which the pin terminals 2 are held, the predetermined intervals and angles of each set of terminals can be held until the molding starts. Further, because the springs between a top plate 100 and the cover mold 110 cause changes in the pressure and speed of mold clamping to the decreasing direction, the breakage and wear of the mold mandrels is reduced. Furthermore, because the pin terminals are held by means of the springs 222 in the mandrels 220 and the springs 125 in the mold 110, the wear of cavity parts due to the holding of the pin terminals is reduced.
