Embodiment Construction

[0092] Hereinafter, embodiments of the present invention are described with reference to the drawings. figure 1 is a schematic diagram showing a liquid supply system 1 according to an embodiment of the present invention.

[0093] A liquid supply system 1 according to an embodiment of the present invention is used to supply a required amount of an undiluted solution (active ingredient) of a mold lubricant to a metal mold surface to be coated during the manufacture of a metal article by die casting. Portions 20A, 20B, 20C, 20D, and 20E of the lubricant (hereinafter referred to as "target portions 20A to 20E"). In the present invention, "die casting" refers to a casting method realized by casting molten metal in a mold. Examples of molding include low pressure molding, high pressure molding, vacuum pressure molding, extrusion molding, non-porous molding, partial pressure molding, NI (New Injection) method, semi-molten molding, semi-solid molding, Die molding, low speed fill mo...

Abstract

The present invention provides a liquid supply device which can supply a required amount of liquid to a liquid supply target part on the surface of a metal die accurately within a short time. The device also enables the cost to be reduced. The liquid supply device (1) comprises injectors (8A-8E) and a driving mechanism (9). The injectors (8A-8E) possess working cylinders (10A-10E) and are inserted into the plunger rods (11A-11E) in the working cylinders (10A-10E) respectively. The cylinders (10A-10E) are moved by the driving mechanism (9), the motion of the working cylinder (10) relative to the plunger rod (11) in each injector is generated, so that the liquid is sucked into the working cylinder (10) at an amount corresponding to a relative stroke distance or is discharged out of the working cylinder (10).

Description

technical field [0001] The present invention relates to a liquid supply device capable of supplying a desired amount of liquid to a target portion on the surface of a metal mold, a liquid supply system having such a liquid supply device, and a liquid supply method using the device and the system. Background technique [0002] During the manufacture of metal articles by die casting, a mold lubricant is applied to the metal mold surface before the metal mold is filled with molten metal. This mainly prevents the final metal article from fixing (sticking) to the metal mold. Also, before coating, the mold lubricant is mixed with a solvent such as water to lower the temperature of the metal mold heated by the previously supplied molten metal. [0003] Figure 24 A heretofore known liquid supply system 100 for applying mold lubricant is shown. The liquid supply system 100 includes an undiluted solution tank 2 , a water tank 3 , a premixing device 4 , a pressurized delivery device...
