Summary: | PURPOSE: A pipe injection mold is provided to separate a core from raw materials by separating end parts after the hardening of the injected raw material, thereby molding a pipe at one injection by using a resin. CONSTITUTION: A pipe injection mold(10) comprises a mold body(100), a core(200), and a cooling unit(300). The mold body includes a first mold body(110) and a second mold body(120) in order to seal or open a mold cavity unit for forming a pipe. The mold body is provided with a supply passage(140) into which a raw material is injected after being melted in the mold cavity unit. The core is provided with a fixed space from the inside of the mold cavity unit to form a passage inside the pipe. The cooling unit cools the core to harden the injected raw material. The core comprises one end part which are detachable and which separates the hardened raw material from the core, thereby performing the molding of a pipe. |
