Zusammenfassung: | PURPOSE:To form electrocast shells for raised and recessed dies in an electrocasting cell at a time by using an electrocast model as a conductive panel, forming pressing surfaces of both raised and recessed dies of product press dies on the front and rear thereof, masking the parts not requiring electrocasting and performing electrocasting. CONSTITUTION:A plate body 12 of a conductive panel is formed by pressing and an electrocast model 5' formed with the raised and recessed surfaces of the male and female dies of setting press molds are made on a front surface 13 and a rear surface 13'. Next, the parts not requiring electrocasting of the surfaces 13, 13' and end parts of the model 5' are masked 14, and the plate body is immersed in an electrolyte in an electrocasting cell 6, whereby metal such as Ni is electrocast on the desired parts of the surfaces 13, 13', and electrocast shells 8', 8'' are formed simultaneously. Next, the shells 8', 8'' removed from the cell 6 are placed on a casting reinforcing material 9, and other reinforcing material 9' is placed thereon to sandwich the shells. Epoxy resins 10, 10' as fixing materials are injected between the shells 8', 8'' are the materials 9, 9', whereby these are fixed. Next, the materials 9, 9' are separated, and only the model 5' is parted from the molds, whereby electrocast shell type presses 11, 11' of male and female dies are manufactured simultaneously. |
