Claims

[Scope of utility model registration request]

A cavity and a core for forming the tank body are arranged between the fixed die set and the movable die set, and a slide core that moves horizontally with an angular pin is arranged on the side of the cavity and core. A slide core insert inserted into the cavity and used to shape the inner diameter of the horizontal part of the pipe is fixed to the side surface of the pipe.
In the mold structure for a resin tank of a heat exchanger in which the end face of the slide core nest can be brought into contact with the side surface of the tank molding part that protrudes upward from the core, the slide core nest is provided with a stepped part, and the stepped part A mold structure for a resin tank of a heat exchanger, characterized in that the mold contacts the side surface of a cavity.
