The present invention may comprise: a first mold having an operation space into which injected material flows, a first outer groove in which an outer sealing member is inserted in an entrance rim of the operation space, a first inner groove which is spaced apart from the first outer groove and allows an inner sealing member to be inserted, a first vacuum groove formed between the first outer groove and the first inner groove, an interlocked space part formed at one side of where a binding block is installed, and a vacuum hole for connecting a discharging hole extended outwardly from the operation space, and the first vacuum groove to communicate with each other; a second mold having an operation protrusion part which is inserted into the operation space, a guide projection which is slidably inserted into the guide hole formed in the first mold, a second outer groove facing the first outer groove, a second inner groove facing the first inner groove, and a second vacuum groove facing the first vacuum groove; a vacuum valve installed in the outer part of the discharging hole, and providing vacuum pressure conveyed from a vacuum pump; a suction block installed movably on the inner side of the discharging hole, and connected to the operation space and the first vacuum groove; and an interlocked part which is installed between the suction block and the vacuum valve, passes through the vacuum pressure conveyed through the vacuum valve and conveys the pressure to the suction block, and converts the upward movement of the second mold into the straight line movement of the suction block and forwards the same, when the second mold is separated from the first mold. |
