Problems solved by technology

[0008] However, in the bearing device disclosed in Patent Document 1, since the casting mold is supported in a direction perpendicular to its rotation axis, when the casting mold is rotated at a very high speed in order to improve the uniformity of thickness, the casting mold can be reliably supported. molding becomes difficult, the mold may vibrate

Embodiment approach 1

[0063] Regarding an embodiment of the present invention, if according to Figure 1 to Figure 6 , Figure 11 , Figure 15 and Figure 16 It will be described as follows.

[0064]

[0065] As a casting machine, as described in Patent Document 2, a structure having a chute is known as a molten metal supply structure of the casting machine. The chute has a groove for receiving molten metal poured from the spout of the ladle, and The received molten metal is directed horizontally.

[0066] Figure 15 It is a sectional view which shows an example of the said casting machine of the conventional example.

[0067] Figure 15 The casting machine 150 shown has: a triangular ladle 103 for supplying molten metal 102 from a fixed ladle 101; a motor 104; a chute 105; a groove (groove) 106; a trolley part 107; 109. The carriage unit 107 has a die 119 ; a sleeve 111 ; and a die rotating mechanism 112 .

[0068] exist Figure 15 In the casting machine 150 shown, since the triangular...

Embodiment approach 2

[0132] Regarding another embodiment of the present invention, if according to Figure 9 ~ Figure 11 It will be described as follows. In addition, for convenience of description, the same reference numerals are attached to components having the same functions as those described in the above-mentioned embodiment, and description thereof will be omitted.

[0133]

[0134] The shapes of both ends of the mold may be other than those described in Embodiment 1.

[0135] For example, if Figure 9 As shown in (a), the mold 200 may also be used. The front end of the mold 200 has a cylindrical shape, and a support portion 200a is provided at a position closer to the center of the mold 200 in the direction of the rotation axis than the front end. The support part 200a is formed in the shape of a truncated cone (that is, a side surface in the longitudinal direction) having an inclined surface having the same inclination angle as that of the end part 1e of the mold 1 in the first embodi...

Abstract

The present invention provides a mold support structure capable of reducing damage to a chute, a casting machine, a method of manufacturing a casting, a mold, and a molten metal supply structure, wherein the molten metal supply structure has: a ladle; and a chute, The chute has a groove for receiving molten metal poured from a ladle and guiding the received molten metal in a horizontal direction, and the ladle has: a ladle body storing molten metal; and a spout , the pouring port is used to pour the molten metal stored in the main body of the ladle to the outside. The main body of the ladle has: a rotating shaft, which makes the pouring port in the direction specified by the pouring direction from the main body of the ladle to the outside and the vertical direction. Rotation in a plane; and a bottom surface extending along the rotation axis, the cross-sectional shape of the bottom surface in a direction parallel to the plane is a first circular arc centered on the rotation axis, the gate is arranged on the bottom surface, and the groove receives molten metal The position of the ladle changes according to the rotation angle of the main body of the ladle.

Description

technical field [0001] The present invention relates to a mold support structure for centrifugal casting, a casting machine, a method for manufacturing a casting, a mold, and a molten metal supply structure having a ladle for pouring molten metal to the outside. Background technique [0002] Among the centrifugal casting machines, as a structure for supporting a mold that rotates during centrifugal casting, for example, a casting machine having a pair of bearing devices provided in the axial direction front and back of the mold described in Patent Document 1 is disclosed. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Laid-Open Patent Gazette "Japanese Patent Application Laid-Open No. 2011-212688 (published on October 27, 2011)" [0006] Patent Document 2: Japanese Laid-Open Patent Gazette "Japanese Patent Application Laid-Open No. 7-204819 (Published on August 8, 1995)" [0007] The problem to be solved by the invention [0...
