での加圧鋳造を実施する事が大変困難で生産性、
品質安定性に問題があつた。 Conventionally, this type of pressure casting apparatus had a structure in which a lead melting pot and a pressure pot were connected through a molten lead supply pipe. With this structure, the molten lead surface in the pressure pot is the same as the molten lead surface in the lead melting pot, and when the molten lead in the pressure pot is consumed, the surface of the molten lead in the pressure pot is When molten lead was injected, the molten lead level in the lead melting pot dropped, and the molten lead level in the pressure pot fluctuated greatly. This means that it is very difficult to carry out pressure casting under constant conditions, which reduces productivity.
There was a problem with quality stability.
本発明は上記の如き欠点を除去するもので加圧
ポツト内の溶融鉛面を常に一定に保ち常に品質の
安定した加圧鋳造による鉛蓄電池用格子体を提供
するものである。 The present invention eliminates the above-mentioned drawbacks and provides a pressure-cast lead-acid battery lattice body which maintains a constant level of molten lead in a pressurized pot and has stable quality at all times.
本発明の一実施例を説明する。 An embodiment of the present invention will be described.

供給されるように構成されている。 1 is a lead melting pot, and a lead ingot introduced from lead inlet 2 is heated by a heater to become molten lead 3, and the temperature of molten lead 3 can be set and controlled arbitrarily between 300℃ and 600℃, and Molten lead 3 is supplied from lead melting pot 1 to lead melting auxiliary pot 5 connected via molten lead supply valve 4. During supply, lead melting pot 1 is compressed with lead inlet 2 closed. The structure is such that molten lead 3 is supplied by pressure from compressed air from air communication pipe 6 .

供給される様に調整されている。 7 is a molten lead supply valve body provided in the lead melting auxiliary pot 5, and the pressure pot 9 connected from the lead melting auxiliary pot 5 via the molten lead supply pipe 8 is connected to the pressure pipe. It is closed when the molten lead 3 is injected into the mold of the lattice body when it is pressurized by compressed air from the compressor 11 connected through the compressor 10, and it opens when the molten lead 3 injection is completed when it is not pressurized. The pressure is adjusted so that molten lead 3 is supplied into the pressurizing pot 9.
１２は溶融鉛３を加圧ポツト９内に供給する際

酸化鉛の発生を防止する溶融鉛乱流防止壁であ
る。 Reference numeral 12 denotes a molten lead turbulent flow prevention wall that prevents the generation of lead oxide by preventing the undulation of the lead surface that occurs when the molten lead 3 is supplied into the pressure pot 9.

３の供給が停止する。 In order to pressurize the lattice body, first the mold 1 is opened and closed from side to side and moved up and down by an air cylinder, etc.
The sprue part 14 of No. 3 is attached to the nozzle part 15 of the pressure pot 9. Next, the molten lead 3 from the lead melting pot 1 is supplied by compressed air into the lead melting auxiliary pot 5 through the molten lead supply valve 4, and also into the pressure pot 9 from the lead melting auxiliary pot 5 through the molten lead supply valve. When both molten lead surfaces 16 supplied through the body 7 rise and reach the specified surface, the liquid level sensor 17 installed in the lead melting auxiliary pot 5 is activated, and the liquid level sensor 17 is configured in advance to operate in conjunction with this. The molten lead supply valve 4 is closed, and the supply of molten lead 3 from the lead melting pot 1 to the lead melting auxiliary pot 5 and the pressure pot 9 is stopped.

れる。 In this state, the compressor 11 is operated to send compressed air from the pressurizing pipe 10 into the pressurizing pot 9 to pressurize it, thereby injecting molten lead 3 from the pressurizing pot 9 into the mold 13 at high pressure. After the molten lead 3 is injected, the mold 13 rises, and at this time the compressed air in the pressure pot 9 is discharged to the outside through an exhaust pipe 19 through an exhaust valve 18 attached to the pressure pipe 10.

可能となる。 In this way, the molten lead level in the pressure pot 9 and lead melting auxiliary pot 5 decreases due to injection from the pressure pot 9, but the liquid level sensor 17 operates and the molten lead supply valve 4 opens, and the molten lead increases. Since the lead 3 is supplied immediately, a constant level of molten lead is always maintained in the pressure pot 9 before pressurization, so that the mold 13 and the pressure pot 9
The distance between the molten metal surfaces within the mold is always constant, and once the pressure conditions are adjusted, pressure casting can be performed under stable pressure casting conditions.

り左右される。 On the other hand, the pressurization method in the pressure pot 9 is such that when the molten lead 3 is injected into the mold 13, it is initially pushed up with a minute pressure of 0.1Kg/cm 3 to 0.4Kg/cm 3 so as not to generate turbulence. Finally, two-stage pressurization is performed in which injection is performed into the mold 13 at a high pressure of 5 kg/cm 3 to 7 kg/cm 3 . This first
The stage pressurization conditions depend on the position of the hot water level in the pressurizing pot 9.
