The present invention relates to a mold injecting device of a plastic molded article, and especially to the mold injecting device of the plastic molded article in which the duration is improved by compactifying cooling lines. The present invention comprises: upper and lower dies (4,5) respectively and correspondingly installed on the upper and lower molds (2,3), which forms an injection mold part (1) by matching as a pair. With the plastic molded article of the mold injecting device which is comprised of upper and lower plates (6,7) respectively moving the upper and lower dies (4,5), movable blocks are installed towards the injection mold part (1) in the lower mold (3) of the lower die (5). The each movable block (8a,8b) is respectively connected with each related pushing arms (9a,9b) and is operated upward and downward, and the undercut molding part (11), which is inserted and disjoined towards the inside of the undercut part (10) of the injection mold part (1) formed between the upper mold (2) and the lower mold (3), is installed in a status of connection with one side of the movable block (8b). In the upper die (5) and lower die(3) installed on the lower plate (7), the passage line (12), in which cooling water inflows and outflows, is supported by the oil-less dual unit (13) which is installed on the lower die(7). |
