The present invention relates to a molding apparatus for an applying-surface-extended tunnel gate and, more specifically, to a molding apparatus for an applying-surface-extended tunnel gate having a structure wherein a slide core forming a runner part and a gate part to a tunnel gate formed on the bottom surface of the mold is correspondingly inserted by sliding when the mold is closed. Accordingly, as opposed to the existing molding apparatus which causes problems related to the location and depth of the tunnel gate on the bottom surface of the mold and a weak injection pressure due to the shape and the molding of the product, the location of the tunnel gate is freely selected, the application of the gate is extended to the interior of the product regardless of product shapes, and specialized molding is also possible with a general mold. |
