New description: [New technical field] The present invention relates to a mold, and more particularly to a forging die. [Prior Art] According to the first figure and the second figure, a forging die for molding a probe terminal, the forging die comprising a male die (not shown) and a master die 100', the master die 100 'Includes an outer mold 10', an inner mold 20' and a thimble 30'. An inner cavity 11' is defined downwardly at a middle portion of the top surface of the outer mold 10', and the inner mold 20' is press-fitted into the inner cavity 11' of the outer mold 10' by a cold press, and the middle portion of the inner mold 20' is middle. There is a cavity 21' extending through the inner mold 20' and a thimble hole 22' communicating with the cavity 21', and a thimble 12 extending through the inner cavity 11' is opened from the bottom surface of the outer die 10'. ', the thimble 30' extends into the cavity 21' through the thimble groove 12' and the thimble hole 22'. However, in the forging die, the inner mold 20' is easily damaged by continuous extrusion of the material, since the inner mold 20' is press-fitted into the inner mold cavity 11' of the outer mold 10' by a cold press, and is replaced. The inner mold 20' is very difficult, and it is usually necessary to replace the outer mold 10' together, thereby increasing the cost of use. [New Content] The purpose of the present invention is to overcome the deficiencies in the prior art described above, and to provide a forging die which is easy to replace the inner mold and can effectively reduce the use cost. In order to achieve the above object, the present invention provides a forging die comprising a male mold and a female mold which cooperates with the male mold in an up and down position, the female mold further comprising an outer mold, an inner mold, a pressing block and a fastener. . A cavity is formed downward at a middle portion of the top end of the outer mold, and an inclined fixing hole extending downwardly to the cavity is formed on the outer side wall of the outer mold; the inner mold is accommodated in the cavity of the outer mold, and the middle portion of the top end of the inner mold is opened. The utility model has a cavity, wherein the lower end of the inner mold protrudes outward to form a convex block; the pressing block is received in the cavity of the outer mold, the pressing block abuts against the convex block of the inner mold, and one side of the pressing block forms a tilting push M406476 The slanting surface is fastened; the fastener is detachably mounted in the inclined fixing hole and abuts against the slanting surface. As described above, since the inner mold is fixed in the cavity of the outer mold by the pressing block and the fastener, the inner mold can be replaced by the disassembly and assembly of the fastener and the pressing block. [Embodiment] In order to explain in detail the technical contents, structural features, achieved goals and effects of the present invention, the following is a detailed description with reference to the drawings. Referring to the third figure, the present forging die includes a male mold and a female mold 100 that cooperates with the upper and lower positions of the male mold. The female mold 100 further includes a base ¥10, an outer mold 20, and an inner mold 30. A pressing block 40, a thimble 50, a fastener 60 and a base 70. Referring to the third and fourth figures, the base 10 has a loading platform 11 and a cylindrical projection 12 extending downward from the carrier. The base 10 is provided with a thimble through hole 13. The outer mold 20 has a cylindrical body, and a rectangular cavity 21 is defined in the middle of the top end of the outer mold 20. A receiving groove 22 communicating with the cavity 21 is opened from the middle of the bottom end of the outer mold 20, and the receiving portion 22 is disposed. The base 22 is fixedly disposed in the slot 22, and the slot wall of the lower portion of the receiving slot 22 is provided with a thread 23, and the outer side wall of the upper portion of the outer mold 20 is respectively opened in two opposite vertical directions with respect to the rectangular cavity 21. The horizontal fixing hole 24 extending horizontally to the cavity 21 and the inclined fixing hole 25 extending downwardly to the cavity 21, in the embodiment, the horizontal fixing hole 24 and the inclined fixing hole 25 are a screw hole. The inner mold 30 is received in the cavity 21 of the outer mold 20, the inner mold 30 is pressed against the base 10. The inner mold 30 is substantially in the shape of an "L", and a cavity 31 is formed in the middle of the top end of the inner mold 30. A lower end of the lower end of the die 30 protrudes outwardly to form a projection 32. The inner mold 4 M406476 • 30 defines a ejector groove 33 which communicates with the cavity 31 and penetrates the inner die 30 downward. The pressing block 40 is received in the cavity 21 of the outer mold 20. The lower end of the pressing block 40 has a slot 41 at the side, and the pressing block 40 abuts against the bump 32 of the inner mold 30. In the slot 41, an inclined chute is formed on the outer side surface of the pressing block 40 to form an inclined pushing inclined surface 42. The ejector pin 50 is movably disposed in the thimble through hole 13 and the ejector groove 33, and the upper end of the ejector pin 50 can extend into the cavity 31 of the inner mold 30. The fastener 60 is detachably mounted in the slanting fixing hole 25 and abuts against the slanting surface 42. In the embodiment, the fastener 60 is a fastening screw, and is screwed into the screw hole. The inclination is fixed inside the hole 25. The pedestal 70 defines a through hole 71 and two operating holes 72. The pedestal 70 is mounted in the accommodating groove 22 by the thread 23 of the outer mold 20. The convex portion 12 of the base 10 It is inserted into the perforation 71. The base 10 of the forging die is received in the receiving groove 22 of the outer die 20. The base 10 is fixed to the outer die 20 by the base 70, and a part is inserted into the two operating holes 72 to disassemble the base 70. In the accommodating groove 22, the inner mold 30 and the pressing block 40 are placed in the cavity 21 of the outer mold 20, and the horizontal fixing hole 24 is provided with a fastener 60 and the fastening member 60 is abutted against the inner mold 30. When the inner mold 30 is damaged during the forging die forging, only the inner mold 30 needs to be replaced. When the inner mold 30 is replaced, it is only necessary to remove the base 70, take out the base 10, and then take out and replace the inner mold 30. In summary, since the inner mold 30 is fixed in the cavity 21 of the outer mold 10 by the pressing block 40 and the fastener 60, the forging die can be facilitated by the disassembly and assembly of the fastener 60 and the pressing block 40. The inner mold 30 is replaced.
