Abstract
PURPOSE: To enable the molding of shape that thickness is thin and depth is deep by a mechanism wherin gates for flowing resin in which are formed to an end surface are made up in structure which their width becomes wider toward the molding space sides from intermediate section narrowing portions.
CONSTITUTION: Gates 11 for flowing resin in are formed to ensure that B-B is the minimum sectional area, their width downward becomes wider toward the gate cavity sides 111, and their width upward becomes wider toward the gate plunger sides 112. When the resin is flowed into a cavity 10 through the gates with such structure, the resin is easy to flow in, and is difficult to flow on the B-B surfaces, but the resin is easy to flow because the gates 11 are formed indownward wide shapes and distance up to the cavity 10 is short after the resin passes through the B-B surfaces. After the resin hardens, the resin is cut at the B-B surfaces, and the resin is removed from a mold as the lower portions of the B-B surfaces are left as they attach to a product. After-working is easy because the quantities of the portions are less than conventional methods.
