Abstract

A mold apparatus for producing a hollow molded article, which can cope with a hot runner specification and facilitate operations for exchanging consumptions of a film formation apparatus or the like without difficulty for arranging a sprue, and a method for producing a hollow molded article. The mold apparatus includes a first molding part for molding a first divided body and a second molding part for molding a second divided body between a first mold and a second mold, and further includes a film formation part in addition to the molding parts, so as to mold a hollow molded article, wherein the film formation part, the first molding part and the second molding part are linearly arranged in this order.

Description

technical field [0001] The present invention relates to a mold device for producing a hollow molded product and a method for producing the hollow molded product, and more particularly, to a mold device for producing a hollow molded product including a film-forming surface and A method for producing the hollow molding. Background technique [0002] Generally, it is known to mold hollow moldings by die slide injection. [0003] For example, in the description of Japanese Patent Laid-Open No. H02-038377, there is proposed a method for molding a separated body by a pair of male and female dies (primary molding), sliding one mold to separate A method in which bodies face each other and then melt the bodies onto each other with a molten resin (secondary molding) to mold a hollow molded article. [0004] Such as Figure 7A As shown, this method uses a fixed mold 102 having a single gate 112 , a slide mold 103 that moves to two positions along the fixed mold 102 , and a movable mo...
