Description

  The present invention relates to a casting apparatus that injects molten metal into a mold and molds a casting, and in particular, facilitates the injection of molten metal into a mold cavity by moderately tilting the mold, and the molten metal in the cavity. TECHNICAL FIELD The present invention relates to an electromagnetic pump pouring mold tilt casting apparatus for replenishing molten metal corresponding to a shrinkage volume of metal during solidification by pouring with an electromagnetic pump and a casting method using the same.

In the field of casting and the like, there are generally a gravity casting method, a low pressure casting method, a die casting method and the like as a method for casting a casting, and there is a Cosworth type casting method having these features.
A conceptual diagram of an example of a gravity casting apparatus is shown in FIG. A space part in which molten metal such as a sprue 43, a runner 45, a cavity 48, etc. is passed or filled is formed in a mold 41 assembled by connecting the half mold with pins 49 as positioning means. The molten metal is drawn up from a crucible (not shown) using a pouring bath 42 and poured into the pouring gate 43. The molten metal poured into the gate 43 passes from the bottom 44 serving as a hot water reservoir through the runway 45 on the bottom side of the mold 41, rises to the side pushing portion 46, and fills the cavity 48 from there through several weirs up and down. Is done. Further, the molten metal having a volume corresponding to the shrinkage during solidification of the molten metal is supplementarily filled into the cavity 48 from the side pressing portion 46 and the upper pressing portion 47.

  A conceptual diagram of an example of the low-pressure casting apparatus is shown in FIG. The inside of the crucible 52 heated by the heating furnace 51 is set as a sealed space, and a compressed air pipe 56 that sends compressed air to the space is provided. Compressed air is sent from the compressed air pipe 56 into the crucible 52 to increase the pressure in the crucible 52, whereby the molten metal in the crucible 52 is sent through the stalk 53 to the cavity in the mold 54 installed on the furnace lid 55. Then fill and cast the casting. When the molten metal contracts as it solidifies, compressed air is further fed from the compressed air pipe 56 into the crucible 52 to additionally fill the contracted volume. The mold 54 is a half-divided divided mold, and after filling and solidifying the molten metal, the mold 54 is separated and the casting is taken out.

  FIG. 9 shows a conceptual diagram of a Renault low pressure casting apparatus as another example of the low pressure casting apparatus. In this method, the casting machine 61 provided with the mold and the furnace 62 are provided separately, compressed air is sent from the squeeze pump 66 into the furnace 62, and the molten metal in the furnace 62 passes through the stalk 64 and the connecting pipe 65 to form the mold 63. Cast into the cavity inside. The mold 63 is moved up and down by a casting machine 61 including an elevator. Other operations are basically the same as those of the apparatus shown in FIG.

  FIG. 10 shows a conceptual diagram of a Novatom type low pressure casting apparatus as an example of a casting apparatus derived from the low pressure casting apparatus. In this Novatom type low-pressure casting apparatus, the mold 73 is moved up and down by a casting machine 71 including an elevator as in the above-described Renault low-pressure casting apparatus. Here, the electromagnetic pump 75 is immersed in the open furnace 72, and the molten metal is sent from the furnace 72 side to the mold 73 through the hot water supply pipe 74 using the electromagnetic pump 75. Other operations are basically the same as those of the apparatus shown in FIG.

  A conceptual diagram of an example of a die casting apparatus is shown in FIG. Molten metal is injected into the sleeve 82, and molten metal is injected and injected from the sleeve 82 into the cavity 87 of the mold 83 by the cylinder mechanism 84. The casting in the cavity 87 of the mold 83 is clamped by a clamping cylinder 86 of the casting machine 81. The casting machine 81 is provided with an extrusion cylinder 85. When the molten metal injected into the cavity 87 of the mold 83 is solidified, the mold 83 is moved, and the casting is pushed out of the cavity 87 by the extrusion cylinder 85 and discharged. The

  Among the gravity casting apparatus, the low pressure casting apparatus, and the die casting casting apparatus shown in FIGS. 7 to 11, except for the Novatom type low pressure casting apparatus shown in FIG. 10, air is poured into the molten metal when the molten metal is poured into the gate. When the molten metal in the crucible is scooped up with a scissors, floating solids such as oxide floating on the molten metal surface are mixed. On the other hand, in the Novatom type low pressure casting apparatus shown in FIG. 10, since the molten metal is filled into the mold cavity through the pipe from a position below the liquid level of the molten metal in the furnace, it is not mixed by entrainment of air or oxide. Not a little. However, the solidification time of the molten metal in the cavity is long, and there is a drawback that it is difficult to supply the molten metal to the furnace and to maintain the electromagnetic pump.

  The Cosworth type casting method was developed to eliminate these drawbacks, and is described in Japanese Patent Application Laid-Open No. 62-234653, which is Patent Document 1 below. The outline is shown in FIG. A mechanical molten metal pump such as a plunger pump system or an electromagnetic pump 95 is used, and the end of the duct 94 is connected to a joint 97 provided on the mold support 96 in a detachable system.

  First, as shown in FIG. 12A, the duct 94 is connected to the joint 97 of the mold support 96 and the mold 93 is placed on the mold support 96. The molten metal is filled into the cavity of the mold 93 attached to the mold support 96 through the mold support 96. After filling of the molten metal into the cavity of the mold 93 is completed, the mold support 96 and the mold 93 attached to the mold support 96 are rotated by 180 ° by the rotation mechanism 98 of the casting machine 91, and the mold 93 as shown in FIG. Is suspended below the mold support 96. When the molten metal shrinks as it solidifies, the molten metal on the mold support 96 side becomes a hot water and is additionally filled so as to compensate for the shrinkage volume by its gravity. In this state, after the molten metal in the cavity of the mold 93 is solidified, the mold 93 is detached from the casting machine 91 and separated, and the casting is taken out.

This Cosworth type casting method has an advantage that many castings can be efficiently manufactured by repeating casting, demolding, and reassembly with the mold 93.
However, when casting a large casting by this Cosworth type casting method, a large rotating mechanism for rotating a large mold is required. In addition, when casting a large casting by this Cosworth type casting method, a mold support that serves as a hot water inside the mold to replenish the shrinkage of the molten metal that solidifies in the mold and secure the height of the hot water. It is necessary to take a large volume of 96.

The cavity of the mold was supplementarily filled with an electromagnetic pump. More specifically, the mold is tilted so that the mold inlet is positioned above the cavity, and the molten metal is pressurized and conveyed by the electromagnetic pump and injected into the cavity. The molten metal in the cavity is solidified by being tilted so as to be positioned on the lower side. The shrinkage of the metal accompanying the solidification at this time is replenished from the inlet below the cavity by the pressurized conveyance of the electromagnetic pump.

  That is, the electromagnetic pump pouring type mold tilt casting apparatus according to the present invention is for casting molten metal into the cavity 24 of the mold 4 by the combined use of the pressurized conveyance of molten metal by the electromagnetic pump 5 and gravity.
