Description
前記一方の型と他方の型が開閉可能に設けられ、
前記一方の型と他方の型とが対向する面の少なくとも一方に成形空間が形成され、
前記一方の型と他方の型のそれぞれに前記成形空間と連通する流路が該流路の軸心を前記対向する面へ向けて設けられ、
前記成形空間内に中子が配設されていることにより上記目的を達成する。
本実施の形態の射出成形用金型1は、固定金型2(一方の型)と、可動金型3(他方の型)と、可動金型3に取り付けられた円柱状の中子4(第3の型)とから構成され、これらの内部に未硬化のゴム材料の流路が形成され、さらに、固定金型2と可動金型3とが対向する面(すなわちPLの面)に成形体を成形するための成形空間がそれぞれ形成されている。34は、可動金型3に形成された成形空間を示し、参照符号24は、固定金型2に形成された成形空間を示している。未硬化のゴム材料の流路は、当該未硬化のゴム材料を金型へ注入する際の注入口となるスプール部と、スプール部からゲート部へ当該未硬化のゴム材料を通すためのランナー部とランナー部から成形空間へ当該未硬化のゴム材料を注入するゲート部とから構成されている。
