摘要

The present invention relates to a device for manufacturing a septic tank integrally formed with a diaphragm for forming a compartment in the septic tank, the core of the core mold 40 flowing into the inner space (11) 21 of the upper and lower molds (10, 20) A plurality of diaphragms 43 are formed in the 42 and the space 31 of the ejector 30 connected to the guide pins 33 guided to the guide holes 41 of the core mold 40 at every four corners. The intermediate zone 32 introduced into the platen groove 43 is formed, and the recycled polyethylene resin solution is blown into the inner space 11 and 21 into which the core 42 is introduced and the diaphragm 43 by the extruder. In order to manufacture the septic tank 50 in which the diaphragm 52 is integrated, it is to facilitate the quality improvement and manufacturing rather than to form the diaphragm in the conventional septic tank one by one.
