The present invention relates to a mold for extrusion and an RFID-applied typesetting sheet manufactured thereby, and more particularly, to an extrusion that improves durability by reducing damage to a portion vulnerable to stress in the die by extrusion force. It relates to a metal mold and an RFID-applied typesetting sheet manufactured thereby.

In general, methods for forming a material such as aluminum or copper into a product in a desired shape include rolling, forging, and extrusion. In particular, extrusion molding can be easily continuously processed even in complex shapes, and the cross section of the part is designed freely It has the advantage of being able to do so, and is currently widely applied to the manufacture of parts for automobiles and electronic products.

1 is a cross-sectional view showing a main part of the extrusion equipment according to the prior art, and FIG. 2 is an exploded perspective view of the main part of the extrusion equipment shown in FIG.

1 and 2, a container 1 for receiving a billet B, which is an extruded material, and a cross-section of the billet B accommodated in the container 1 are shrunk and are fired to a desired width and thickness. It includes a mold 2 and a dummy block 3 and a ram 4 for pushing the billet B accommodated in the container 1 toward the mold 2.

In addition, a flow guide 5 is installed from the container 1 to the mold 2 to form an extrusion chamber that optimizes the pressure according to the shape of the mold 2 during extrusion. A backer block (6) is installed in the passing part to prevent the mold from being deformed by the pressure applied during extrusion. Typically, the mold 2, the flow guide 5, and the backer block 6 are collectively referred to as an'extrusion mold', and these will be referred to as a'mold set'.

The mold set, that is, the flow guide 5, the mold 2, and the backer block 6 are charged and supported in the mold holder 7, and a bolster 8 is installed from the mold holder 7 toward the extrusion direction. Thus, during extrusion, the mold set is supported more firmly against pressure. Then, both the mold holder 7 and the bolster 8 into which the mold set is loaded are mounted on the carrier 9.

In the conventional extrusion equipment configured as described above, when the ram 4 pushes the billet (B) contained in the container (1), the billet (B) is contracted and deformed while passing through the mold set to the shape designed in the mold (2). The extrudate is molded.

On the other hand, such a conventional technology is a situation that can significantly reduce the mold cost when replacing the mold or applying a large extruder, in order to improve this situation, "extrusion mold "Has been suggested.

However, in such conventional techniques, a large force is applied to the mold by the billet extruded through the flow guide. At this time, when forming a neck that is vulnerable to stress due to the structural stress of the extrusion hole formed to correspond to the product shape in the mold, It had a problem in that it caused damage by the applied extrusion force. Therefore, in terms of improving the durability of the mold, there is a need to develop a technology that can solve this problem.

In addition, when the prior art is applied to a mold for the manufacture of a typesetting paper hanger, when the typesetting paper is hooked to the typesetting paper hanger is 3mm, in order for the typesetting paper to be caught without falling out of the typesetting paper hanger, the part that is caught from the typesetting paper hanger is It should be at least 2.7mm or less, and for this reason, it is inevitable to form a neck with a minimum width of 2.7mm or less even in the mold, and in this case, the problem of the above-described vulnerability becomes more serious.

In order to solve the problems of the prior art as described above, the present invention disperses the extrusion force of the billet applied to the die by allowing the flow guide to divide the billet, which is an extruded material, into a number of them to be fed to the extrusion hole side of the die. , Increases durability by preventing damage to the stress-sensitive part of the die by extrusion force, and by having a tapered cross-sectional structure for the weak part, it plays a role as a die bearing and reduces the resistance when the billet passes through it. The purpose of this is to make a great contribution to the prevention of damage to vulnerable parts, and to facilitate management by using RFID for products manufactured by such extrusion molds.

3 and 4, the extrusion mold 100 according to an embodiment of the present invention may include a flow guide 110 and a die 120. Meanwhile, the flow guide 110 and the die 120 form a mold set together with the backer block, as described in the prior art, and the mold set is supported by being pressed into the mold holder, and the bolster from the mold holder toward the extrusion direction. By being installed, it is possible to more firmly support the mold set against pressure during extrusion. Both the mold holder and the bolster loaded with this mold set can be mounted on the carrier.

3 to 6, the flow guide 110 is separated from each other by the boundary 113 so that the billet transferred from the front is divided into several branches and passed through the flow guide 110 A confluence guide hole 114 is formed at the rear end of each of the branch guide holes 111 and 112 so that the billets passing through the branch guide holes 111 and 112 merge from the rear side to be discharged. Here, the boundary part 113 serves as a partition wall separating the branch guide holes 111 and 112 from each other. By being deleted from the confluence guide hole 114 side, the branch guide holes 111 and 112 join to form the confluence guide hole 114. To be able to form.

The flow guide 110 may have inclined surfaces 111a and 112a so that each of the branch guide holes 111 and 112 is inclined toward the confluence guide hole 114 to merge. Accordingly, the branch guide holes 111 and 112 are formed to be inclined by the inclined surfaces 111a and 112a, thereby dispersing the extrusion force of the billet.

Branch guide holes 111 and 112 are symmetrical or asymmetrical when the extrusion hole 121 in the die 120 is based on a vertical line so as to compensate for the extrusion force of the billet applied according to the shape of the extrusion hole 121 In this case, it is formed to be arranged symmetrically or asymmetrically with respect to the vertical line, or when the extrusion hole 121 in the die 120 is symmetrical or asymmetrical with respect to the horizontal line, It may be formed to be symmetrically or asymmetrically arranged. That is, referring to FIG. 7 in the present embodiment, it can be seen that the extrusion holes 121 in the die 120 are symmetrical horizontally when the vertical line is referenced and vertically asymmetrical when the horizontal line is referenced. Accordingly, the branch guide holes 111 and 112 are configured to be horizontally symmetric when referenced to a vertical line and vertically asymmetric when referenced to a horizontal line, as in the compression molding hole 121, as shown in FIG. 5. This is because the extrusion force of the billet applied to the extrusion hole 121 acts symmetrically for the symmetrical shape of the extrusion hole 121, but has no choice but to act asymmetrically for the asymmetrical shape. In consideration of this, the branch guide holes 111 and 112 are arranged. In addition, in the case of asymmetry, in the case of a structure in which the passage of the billet is relatively difficult, the number of guide holes 112 may be reduced in order to reduce dispersion of the extrusion force, and in the case of a structure in which the passage of the billet is relatively easy, the extrusion force In order to increase the dispersion, it may be configured to increase the number of guide holes 111.

In this regard, for a more specific example, the die 120 includes an extrusion hole 121 having a locking frame having a locking protrusion 14 on the base plate 11, as in FIG. 9, as in this embodiment. 12) to have a shape for extrusion molding the typesetting paper hanger (10) forming a plurality of mounting slots (13), at this time, the branch guide holes (111, 112) are the base plate in the extrusion hole (121) The first branch guide hole 111 formed in the left and right sides corresponding to the area in which (11) is formed, and the second formed in a single unit corresponding to the area in which the locking protrusion 14 is formed in the extrusion hole 121 It may include a spray guide hole 112. Therefore, the first branch guide hole 111 is formed in a pair to disperse the extrusion force, so that the extrusion force for the base plate 11 (refer to FIG. 9) forming region in which the billet is relatively easy to pass through the extrusion molding hole 121 This can be adjusted to be relatively small, and the second injection guide hole 112 is made of a single unit, thereby reducing dispersion of the extrusion force, thereby preventing the billet from passing through the extrusion hole 121 relatively easily. ) It can be adjusted so that the extrusion force for the forming area becomes relatively large despite the dispersion of the extrusion force.

3, 4, and 7, the die 120 is coupled to the rear side of the flow guide 110, and the billet supplied from the confluence guide hole 114 passes through an extruded product having a desired cross section. An extrusion hole 121 is formed to be molded, and an extrusion guide groove 122 for guiding the billet conveyed from the confluence guide hole 114 to be supplied to the extrusion hole 121 at the front end of the extrusion hole 121 is provided. It is formed on the front side. The extrusion guide groove 122 is formed over an area sufficiently including the extrusion hole 121 in the front surface of the die 120, so that the billet supplied to itself can be guided to be easily supplied to the extrusion hole 121 side. .

The die 120 are bolted to the fastening holes 115 formed in the flow guide 110 through fastening holes 123 respectively formed on the upper and lower sides to be coupled in contact with the rear side of the flow guide 110. Can be combined.

Referring to FIGS. 7 and 8, the die 120 may be formed to be tapered so that the width of the neck portion 121a formed by the extrusion hole 121 increases toward the rear, and the neck portion ( 121a) may have a rear width of 1.5 to 2.7 mm. Therefore, as shown in FIG. 9, when the width of the area in which the locking portion of the typesetting paper 20 to be caught between the locking projections 14 in the typesetting paper hanger 10 is located is 3mm, the typesetting paper In order to catch the typesetting paper 20 on the hanger 10, the gap between the locking protrusions 14 must be at least 2.7 mm, and for this reason, the neck portion corresponding to the locking protrusions 14 in the extrusion mold 100 The minimum width of (121a) is 1.5 ~ 2.7 mm, in this case, the cross section of the neck portion (121a) is formed to be tapered, it is possible to increase the durability even during mass production.

The die 120 may be provided with a die bearing stepped to guide the billet passing through the rear side of the extrusion hole 121 to exactly match the dimensions of the product. In this case, the die bearing will act as a resistance when the billet passes through. I can. On the other hand, when the extrusion hole 121 has a neck portion 121a whose width decreases sharply as in this embodiment, in the case of a conventional stepped die bearing structure, damage is caused due to interference with the billet. When the neck portion 121a corresponding to the portion is formed to be tapered, it is possible to minimize interference with the billet and allow the product to be molded to the correct dimensions.
