Rapid high-yield molding device for polypropylene (PP) building formwork

The invention discloses a rapid high-yield molding device for a polypropylene (PP) building formwork, The rapid high-yield molding device for the polypropylene (PP) building formwork comprises a molding rack system, a negative-pressure vacuumizing system, a waterway cooling system, a molding board up-down lifting system and the like. A gas way and a water way of an existing molding table are all black rubber pipe, a gas pipe can bear 0.1 Mpa or below vacuum negative pressure, the negative pressure value of this molding table during normal production is negative 0.02 MPa, and a PU pipeline sufficiently ensures the production of qualified products, so that the waste of the pipeline is greatly reduced, a negative pressure air storage tank is added in the gas way, can well store a certain amount of gas, achieve the function of a buffer, and solve the unstable condition of the gas way. in order to solve the problem that the molding table is not parallel when the molding table retreats, a pinion and rack structure
