Embodiment 1

[0029] Embodiment 1 of the present invention will be described below with reference to the drawings. exist Figure 1~5 Among them, 1 is the flash removal tool of the present invention, indicating that it is used to remove such as Figure 10~1 3 shows a tool for forming flash 113 produced at the opening edge portion 114 of the through hole 103 of the molded product 100. In addition, in the present invention, as symbols representing each part constituting a molded product to be deburred, the same as Figure 10~1 3 common symbols. In addition, the molded article applicable to the burr removing tool of the present invention is not limited to the hollow body, and it is of course applicable to parts of all shapes having molded burrs in the through holes.

[0030] Flash removal tool 1 has entry (direction of arrow A) and exit (direction of arrow B) need to remove the columnar body 2 in the through hole 103 of forming flash 113, and the front end peripheral portion 3 formed along t...

Embodiment 2

[0039] Although in embodiment 1, in order to form the 2nd cutting edge portion 41 (step portion 43) and engrave groove portion 42 on columnar portion 2, also can not provide groove portion but as Figure 6 the shape shown. That is to say, by connecting and fixing the front half part 81 of the columnar body having the first blade part 811 and the second blade part 812 to the front end side of the rear half part 82 of the columnar body with small screws 813 etc., the columnar part 8 is formed. Flash removal tool7. According to this structure, depending on the state of wear of the first blade portion 811 and the second blade portion 812, only the front half of the columnar body 81 can be replaced in some cases, thereby reducing the cost of components. In this burr removing tool 7, the second blade portion 812 is provided on the entire circumference of the side surface of the columnar body 8, and it is also possible to produce residual burrs not only on the long sides of the squa...

Embodiment 3

[0041] refer to Figure 7 Embodiment 3 of the present invention will be described. exist Figure 7 Among them, 8 is the flash removal tool of the present invention, which is a tool for removing forming flash generated at the opening edge of the circular through hole of the molded product.

[0042] The burr removal tool 8 has a columnar body 9 that enters and exits the through hole that needs to remove the formed burr, and a first blade portion 911 formed along the front end peripheral portion 91 of the columnar body 9, and on the side peripheral portion 92 of the columnar body 9. Formed second blade portion 921. A fixed part 10 is formed on the rear end side of the columnar body 9, and the flash removal tool 8 can be fixed on the reciprocating drive cylinder (not shown) as the driving source through the mounting hole 11 provided on the fixed part 10. . The columnar body 9 is formed in a shape corresponding to the opening edge of the circular through hole that needs to be r...

Abstract

A burr removing tool, by making the burr removing tool 1 enter and withdraw from the through hole of a formed product, forming burrs that are not removed when the first blade portion 31 enters and remain on the edge of the opening are formed on the second blade portion 41 Reliably hooks and removes when exiting. The flash removal tool 1 has a columnar body 2, and a first blade 31 having a shape corresponding to the opening edge of the through hole on the outer periphery of the columnar body 2, and a 2 rear end side, and the second blade portion 41 formed toward the rear end side of columnar body 2. This burr removal tool can completely remove molding burrs generated at the opening edge of a through-hole of a molded product.

Description

technical field [0001] The present invention relates to a flash removal tool for removing molding flash generated at the edge of the opening of a through hole formed in a molded product. Background technique [0002] For example, will be as Figure 10 The hollow molded product 100 shown, that is, a part having a through hole 103 connecting the side of the inner side 102 from the side of the outer side 101 is produced by aluminum casting, resin injection molding, powder sintering molding, etc., in the case of On the cross-section X-X, the molding die is as Figure 11 structure shown. That is, the outer surface 101 is formed by the first mold 104 and the second mold 105, the inner surface 102 is formed by the core 106 extending in the vertical direction between the first mold 104 and the second mold 105, and the inner surface 102 is formed by being placed on the second mold 105. The protruding portion 107 on the top forms a through hole 103 communicating the outside and insi...
