Prefoam refers to that EPS beadlet, before adding mould, will first carry out prefoam, so that beadlet expand into certain size.Prefoam process determines the density of model, dimensional stability and precision, is one of key link.The method being applicable to EPS beadlet prefoam has three kinds: hot water prefoam, steam pre-foaming and vacuum pre expansion.The bead foam rate of vacuum pre expansion is high, and beadlet is dried, and applies more.
Ripening refers to certain time in the EPS beadlet of prefoam is placed on feed bin dry, that ventilate.So that extraneous pressure balance in making beadlet abscess, make beadlet have elastic and reflation ability, remove the moisture of surface of beads.Curing time was at 8～48 hours.
Foaming refers to be filled in the die cavity of metal die the EPS beadlet of prefoam and ripening, heating, makes beadlet reexpand, fills up the space between beadlet, and make mutually to merge between beadlet, forms smooth surface, i.e. model.
Must cool down before depanning, make model be cooled to below softening temperature, after model hardening setting, could depanning.Model also should be had after depanning to be dried and the time of dimensionally stable.Equipment has the forming machine two kinds of digester (-tor) and automatic forming.
The second, is moulded board making by bubble: bubble moulds sheet material resistance wire cutting adhesive model.
Bubble is moulded the model needed for plate cutting becomes by naive model resistance wire cutting device.
To complex model, first use resistance wire cutting device, model is divided into several part, then carries out bonding, make block mold.
And carrying out bonding combination to make Bai Moshi at needs, existing way is to be realized the combination of interface by brushing paint or bonding agent, but, white mould drying course there will be the situation of interface fracture, it is therefore desirable to improve.
Utility model content
