Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the support of a stuffing material for supporting a stuffing material in a mold by using a wire in the production of a composite casting in which a stuffing material of a different material is cast inside a casting body. About the method.

[0002]

2. Description of the Related Art In general, a composite casting in which a cast-in material different from the material of the cast body is cast inside a cast body is manufactured. In this production, a composite casting is produced by previously supporting a cast-in material in a mold and pouring the material into the mold. Conventionally, as a method of supporting a cast-in material in a mold, there is, for example, a method of spreading the cast-in material on the surface of the mold. According to this, the surface layer of the cast-in material different in material is formed in the casting by pouring,
Since the cast-in material is on the surface of the casting mold, the cast-in material cannot be completely compounded by the movement of the supplied molten metal, and the cast-in material cannot be put inside. Also, conventionally,
There is a method of installing a support member inside a mold and fixing a cast-in material to this support member, but at the time of pouring, the support member is strongly affected by heat and is melted or deformed, or flows due to molten metal. May be lifted,
There is a disadvantage that the position of the stuffing material inside the casting changes, and it is difficult to stuff in a fixed position.

In order to solve such a drawback, conventionally, as shown in FIG. 9, in a mold K composed of an upper mold 1 and a lower mold 2, wires 4 are fixed to both sides of a cast-in material 5. After supporting the end of the wire 4 at a predetermined position on the mold dividing surface 3 of the lower mold 2 and laying the cast-in material 5 in the lower mold 2, the upper mold 1 is placed on the lower mold 2, and the wire 4 is Hold from above. That is, the cast-in material 5 is fixed by sandwiching the wire 4 between the mold division surfaces 3 of the upper mold 1 and the lower mold 2. Thereafter, the casting is made by pouring the wire 4 from a pouring port (not shown) provided in the upper mold 1 (for example, disclosed in JP-A-57-25275). .

[0004]

However, in the conventional method of supporting a cast-in material as shown in FIG. 9, the position of the cast-in material 5 in which the cast-in material is cast is defined by the upper mold 1 and the lower mold 1 at the mold dividing surface 3 of the mold K. The position is limited to the position where the wire 4 can be sandwiched between the molds 2, and there is a disadvantage that the degree of freedom in positioning the insert material 5 is small. In order to increase the degree of freedom, it is conceivable that the wire 4 for fixing the cast-in material 5 is directly provided on the mold K.
Since the wire 4 must be bonded and fixed after shaving the wall portion, the operation is complicated and the production efficiency is poor. In addition, depending on the position of the wire 4, there may be a case where a mold cannot be substantially formed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and allows the position of an as-cast material to be freely set.
It is another object of the present invention to provide a method for supporting a cast-in material which facilitates the support of the cast-in material at the time of cast-in and improves the working efficiency.

[0006]

The technical means of the present invention for solving the above problems is to provide a method of supporting a cast-in material in a mold by using the wire to support the cast-in material. One end is fixed to the cast-in material, and the other end of the wire is provided with a support block for supporting the other end of the wire, while the mold is provided with a fitting recess in which the support block is fitted, and The support block is fitted in the fitting recess to support the cast-in material. Accordingly, when the fitting concave portion is formed in the mold, it is formed, for example, by molding or the like at the time of manufacturing the mold. In this case, since the fitting concave portion can be formed by molding or the like, it can be formed very easily at an appropriate position, and therefore, the degree of freedom in positioning the cast-in material is greatly increased. When the mold is assembled, the support block is fitted and fixed in the fitting recess of the mold. In this case, the position of the cast-in material can be determined only by fitting the support block into the fitting concave portion, and the support of the cast-in material becomes extremely easy, thereby improving the working efficiency.

[0007] It is effective that an adhesive is interposed between the fitting recess and the support block as required.
Since the support block is fixed with an adhesive, the support is stabilized. Further, the support block is formed of a sand material as required. When removing the mold, it is only necessary to break the mold in the same manner as the upper mold and the lower mold made of the sand mold, and the removing work becomes easy.
Further, if necessary, the support block is formed of a metal material. Since it is a metal material, it can be left as it is even after demolding, and can be used repeatedly.

The other end of the wire is bent as required. The wire can be reliably locked to the support block, and as a result, the support of the cast-in material is stabilized. If necessary, the support block is formed of a metal material, and the support block is provided with an engagement portion with which the other end of the wire is detachably engaged. The support block can be supported simply by supporting the wire on the engagement portion, and therefore, the support of the support block is facilitated, and the workability is improved. Furthermore, if necessary, a plurality of sets of the wire and the support block are provided, and the fitting recesses are formed in the molds respectively corresponding to the plurality of support blocks. Since the cast-in material can be supported at multiple locations,
It is possible to more reliably support the cast-in material.

Therefore, the degree of freedom in positioning the insert material 5 is greatly increased, and various insert products can be formed. Be able to respond. The support block 10 is fitted and fixed to the fitting recess 20 via an adhesive.

Therefore, when forming the mold of the mold K,
An adhesive is applied to the support block 10 and the upper mold 1 of the mold K is formed.
The support block 10 is fitted and fixed in the fitting concave portion 20 of FIG. As a result, the cast-in material 5 is suspended from the upper mold 1 via the wire 4. In this case, the positioning of the cast-in material 5 can be performed only by fitting the support block 10 into the fitting concave portion 20, the support of the cast-in material 5 becomes extremely easy, and the working efficiency is improved. Further, since the support block 10 is fixed with an adhesive, the support is stable. Further, since the other end 4a of the wire 4 is bent in an L-shape, the wire 4 is securely locked to the support block 10, and the support of the cast-in material 5 is stabilized. Next, the upper die 1 on which the support block 10 is suspended
Is set in the lower mold 2 and the cast-in material 5 is positioned at a predetermined position in the mold.

In this state, the molten metal is poured from the pouring port 6. Thereby, the molten metal is gradually filled in the mold, and the cast-in material 5 is cast around by the cast iron material. In this case, the wire 4 remains in the cast iron material,
Alternatively, it is melted and mixed into the cast iron material. If the cast iron material is solidified in the cast-in state, it is released from the mold. In this case, it is only necessary to break the upper mold 1 and the lower mold 2 made of a sand mold together with the support block 10 made of a sand material, and the mold can be easily removed. Thereafter, the surface treatment of the casting is appropriately performed. In this case, if the wire 4 has protruded, it is cut. Thereby, a cast product in which the super steel alloy is cast is manufactured.

Next, a method for supporting a cast-in material according to a second embodiment of the present invention will be described. This is substantially the same as the first embodiment, but different from the first embodiment, as shown in FIGS. 4 and 5, a plurality of sets of the wire 4 and the support block 10 are used. In the form of 2 sets)

Further, the fitting concave portion 20 is exposed at the lower end surface of the side wall of the upper die 1, that is, the mold dividing surface 3 with the lower die 2 of the upper die 1, and is molded corresponding to the support block 10. The support block 10 is formed in a rectangular shape large enough to be fitted. Therefore, when forming the mold K, an adhesive is applied to the support block 10 and the support block 10 is fitted and fixed in the fitting concave portion 20 of the upper mold 1 of the mold K. Thereby, the cast-in material 5 is supported on the upper mold 1 via the wire 4. In this case, since the support block 10 is fixed with an adhesive, the support is stable. Also, since the cast-in material 5 is supported by the wire 4 from both sides,
Support is stable. Other operations and effects are the same as those of the first embodiment.

Next, a method for supporting a cast-in material according to a third embodiment of the present invention will be described. This is substantially the same as the first embodiment, but different from the first embodiment, as shown in FIGS. 6 and 7, a plurality of sets of the wire 4 and the support block 10 are used. In the form of 2 sets)
Is provided. The wire 4 is fixed above and below the cast-in material 5. The support block 10 is formed in a rectangular shape. Further, the fitting recess 20 is provided in the upper mold 1 and the lower mold 2. The fitting concave portion 20 of the upper die 1 corresponds to the upper support block 10 and is formed in a rectangular shape having a size in which the support block 10 is fitted to an intermediate portion of the side wall of the upper die 1. On the other hand, the fitting recess 20 of the lower die 2 corresponds to the lower support block 10, and is exposed on the dividing surface 3 between the lower die 2 and the upper die 1, and the support block 10 is inserted from above. It is molded so as to fit. Therefore, when forming the mold K, an adhesive is applied to the upper support block 10 and the upper support block 10 is fitted and fixed to the fitting recess 20 of the upper mold 1 of the mold K. This allows
A cast-in material 5 is supported on the upper mold 1 via a wire 4.
Next, an adhesive is applied to the lower support block 10, and the upper block 1 is installed on the lower mold 2 while the support block 10 is inserted from above into the fitting recess 20 of the lower mold 2 and fitted. Then, the cast-in material 5 is positioned at a predetermined position in the mold. In this case, since the support block 10 is fixed with an adhesive, the support is stable. Further, since the cast-in material 5 is supported by the wire 4 from above and below, the support is more stable. Other operations and effects are the same as those of the first embodiment.
