て、処理できる鋳物は外形が単純なものに限られ
ていた。 In recent years, research and development has been conducted on a method for removing unnecessary materials from castings, in which the castings are placed on a fixed table and a cutter is lowered to cut off the unnecessary materials. A so-called external broach structure with multiple layers of blades is used. However, cutters with this broach structure are expensive because the blade structure is complex and takes a lot of time to manufacture.Moreover, the material used is tool steel, which is extremely hard and difficult to machine, so the blade shape is difficult to manufacture. They have a polygonal or circular shape, and therefore the castings that can be processed are limited to those with simple external shapes.

る。 Reference numeral 1 denotes a casting table on which a casting M with unnecessary material D attached is placed, and the upper surface of the casting table 1 has a shape corresponding to the shape of the casting M. Reference numeral 2 denotes a casting presser that presses the casting M on the casting table 1. The casting presser 2 is disposed directly above the casting table 1 so as to be movable up and down via a downward cylinder (not shown). Similarly, the shape corresponds to the shape of the casting M.
3 penetrates the casting M on the casting table 1 to
The cutter mechanism cuts off unnecessary materials from the casting table 1.
It is disposed directly above the cylinder so that it can be moved up and down via a downward cylinder (not shown). The cutter mechanism 3 includes several plate-shaped cutter pieces 4a, 4b,...
a cutter 5 formed by overlapping the cutter 5;
It consists of a hollow cutter mounting head 6 to which the cutter is attached. In addition, cutter pieces 4a, 4b,
. . . is made of tool steel plate, which is very hard, but holes 7a, 7b, . As shown in FIG. 2, since the cut made by the cutting machine C is V-shaped, the holes 7a, 7b, . . . become smaller downward as shown in FIG.
a, 4b, . . . holes 7a, 7b . . . on the lower surface. Appropriate cutting blades are formed on the peripheral edges. The blade thus formed is hardened by cutting with a CO 2 laser cutting machine C and becomes extremely hard. In addition, holes 7a, 7
b, ... are smaller as they are higher up, and the hole 7 at the top
e has approximately the same size as the outer shape of the casting M.

物Ｍを得ることができる。 Next, to explain the operation of this device, a casting M, which has just been demolded and still has an unnecessary material D attached to it, is placed on the casting table 1, a downward cylinder (not shown) is extended and the casting presser 2 is lowered, and the casting M is placed on the casting table 1. Hold M. Next, when the downward cylinder (not shown) is extended and the cutter mechanism 3 is lowered, the lower surface of the cutter 5 first comes into contact with the waste D, and the waste D is broken, and then the hole 7a of the cutter piece 4a is broken.
When the casting M enters the inside, a part of the unnecessary material D remaining on the casting M is cut off, and this action causes other cutter pieces 4 to be cut off.
Steps b and 4c are also carried out sequentially in a short period of time, and as a result, not only the unnecessary material D of the casting M but also the burrs are cut, and the unnecessary material D and the burr are removed from the casting M. After cutting of the unnecessary material D and the like is completed, a cylinder (not shown) is retracted to raise the cutter mechanism 3 and the casting presser 2, thereby obtaining the casting M from which the unnecessary material D and the like have been removed.

を奏する。 As is clear from the above explanation, the present invention
The cutter is made by stacking two or more tool steel plates with holes drilled through a CO2 laser cutting machine to allow the casting to pass through, so it eliminates the need for hardening, is easy and inexpensive to manufacture, and prevents the blade from wearing out. By replacing broken or chipped cutter pieces, you can extend the life of the cutter as a whole.Moreover, since the shape of the cutting blade is the same cutout hole shape as the outer shape of the casting, it can be used not only for runners and risers, but also for runners and risers. It has excellent practical effects such as being able to reliably cut and remove burrs.
