摘要

The die set comprises a lower mold, on whose upper surface, a casting surface is formed in the middle in order to form a cylinder head (101) in the lower surface and in whose outlet side, a core insert opening is formed with a shape of a circular arc, an outlet channel core with a shape of a circular arc, an upper mold on whose lower surface, a casting surface is formed in order to form the cylinder head in the upper surface, and a mold at the outlet side, on which a casting surface is formed to form the cylinder head at the inlet side surface. The die set comprises a lower mold, on whose upper surface, a casting surface is formed in the middle in order to form a cylinder head (101) in the lower surface and in whose outlet side, a core insert opening is formed with a shape of a circular arc, an outlet channel core with a shape of a circular arc, an upper mold on whose lower surface, a casting surface is formed in order to form the cylinder head in the upper surface, and a mold at the outlet side, on which a casting surface is formed to form the cylinder head at the inlet side surface. The outlet channel core is inserted in the core insert opening of the lower mold in order to form an outlet channel. An inlet channel core is formed by the cylinder head in order to form the inlet channel (109). A fixing groove is formed at the side of the rear end of the outlet channel core. A spring element is arranged at the interior end area of the core insert opening in order to support the posterior end of the outlet channel core. The seat grooves are formed at both sides of the casting surface of the lower mold. A fixing section is configured in the outlet side of the lower mold in order to arrive the outlet channel core in the intervention with the fixing groove in such a way that it fixes the outlet channel core. The fixing section comprises a fixing bolt that is arranged in the outlet side of the lower mold in a horizontal direction in such a way that its front end is inserted in the fixing groove of the outlet channel core. A snap-in groove is formed in one side of the fixing bolt and a snap-in groove ball that is configured in the outlet side of the lower mold. A spring resiliently secures the snap-in groove ball in the snap-in groove.
