Detailed description of the invention
Refer to Fig. 1 to Fig. 3, fervent mould in a kind of high pressure nitrogen mould, including the upper mold 1 being oppositely arranged and lower mold 2, on
Mould 1 is positioned at the top of lower mold 2, and lower mold 2 is arranged on mould bases 3, is provided with fervent assembly 5 in mould bases 3, and fervent assembly 5 part is positioned at
In lower mold 2, being additionally provided with the high pressure air flue 4 being connected with fervent assembly 5 in mould bases 3, high pressure air flue 4 connects has source nitrogen (to scheme not
Show), source nitrogen connects time schedule controller, it is therefore an objective to after completing injection and pressurize action, glue oral area divides and also keeps certain
Soft, cutting is easier, it is ensured that cut.Source nitrogen can be by being dried compression by air, then dividing through nitrogen making machine
Son is sieved through air filtering and obtains, it is also possible to directly use bottled high pressure nitrogen as source nitrogen.Use high pressure nitrogen, oil can be solved
Pressure-volume easily reveals hydraulic oil, the pollution causing product.Nitrogen, will not be to the product produced as the clean gas of a kind of torpescence
Product pollute.
Earnestly assembly 5 includes that cylinder block 51, cylinder block 51 have downwardly open air chamber 53, is provided with piston in air chamber 53
52, the top of piston 52 is provided with high-pressure seal ring 54, and piston 52 is provided with through opening (figure is not marked), opening and high pressure air flue
4 connections, the top of cylinder block 51 is provided with cutting knife top board 55, and cutting knife top board 55 is provided with cutting knife 56, and cutting knife 56 includes handle of a knife 561 He
The knife edge 562, handle of a knife 561 and the knife edge 562 are one-body molded, and handle of a knife 561 is positioned at the bottom of cutting knife 56, handle of a knife 561 and cutting knife top board 55
Connecting, the knife edge 562 is positioned at the top of the knife edge, and the width of the knife edge 562 is less than the width of handle of a knife 561, cutting knife 56 and the gap of lower mold 2
Less than 0.005mm, so will not produce batch cutting edge of a knife or a sword when the product of fervent injection mo(u)lding, be provided with between cutting knife top board 55 and lower mold 2
