[0001] This utility model relates to the technical field of cold heading dies, specifically a split-type cold heading die. Background Technology

[0002] Cold heading machine and cold heading mold are molds used on a cold heading machine to cut, pre-form, and shape blanks into cold-formed parts. Cold heading molds are mainly used to form screws, and screws are made through cold heading molds.

[0003] According to Chinese Patent No. CN220717678U, a cold heading die for a cold heading machine includes a main die for stamping; a threaded groove formed in the upper end of the main die; a shaping die installed in the threaded groove by threads; and a fixing component installed on the lower left and right sides of the main die, the fixing component being used to improve the fastening effect when the main die is installed in the cold heading machine.

[0004] In the above scheme, the shaping mold is directly installed inside the main mold by means of threads, which has the following disadvantages: the threads of the shaping mold may be damaged under stamping, which will lead to problems of thread friction and jamming, thereby reducing the service life of the mold. Utility Model Content

[0005] The purpose of this invention is to provide a separable cold heading die to solve the problem that the threads of the forming die may be damaged under stamping, which in turn causes thread friction and jamming, thereby reducing the service life of the die.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a separable cold heading mold, including a shaping mold, the shaping mold being detachably disposed inside a main mold, the shaping mold having two fixing grooves on its left and right sides respectively, the main mold having two fixing holes on its left and right sides respectively, the main mold having fixing plates detachably disposed on its left and right sides respectively, the two fixing plates having two fixing posts fixed on their inner sides respectively, the two fixing posts being slidably inserted into the two fixing holes respectively, the two fixing posts being slidably inserted into the two fixing grooves respectively, the main mold having threaded grooves on its left and right sides respectively, the two fixing plates having first threaded holes on one side respectively, the two first threaded holes having first bolts threadedly connected to them respectively, the threaded ends of the two first bolts being threadedly connected to the inside of the two threaded grooves respectively.

[0007] Preferably, positioning rods are fixed to the front and rear sides of the shaping mold, and positioning grooves are opened on the front and rear sides of the inner wall of the main mold, with the two positioning grooves respectively positioning the two positioning rods.

[0008] Preferably, a bearing ring is fixed to the inner wall of the main mold.

[0009] Preferably, the top surface of the bearing ring is fixed with an anti-slip ring, and the top surface of the anti-slip ring is provided with anti-slip texture.

[0010] Preferably, the outer wall of the main mold is detachably provided with a base, the top surface of the base is provided with two second threaded holes, the left and right sides of the outer wall of the main mold are respectively fixed with mounting plates, the top surfaces of the two mounting plates are respectively provided with mounting holes, the two second threaded holes are respectively threaded with second bolts, the two second bolts are respectively slidably inserted into the two mounting holes, and the threaded ends of the two second bolts are respectively threaded with nuts.

[0011] Preferably, the top surface of the base is fixed with two limiting posts, and the front and rear sides of the outer wall of the main mold are respectively fixed with limiting sleeves, and the two limiting sleeves are slidably sleeved on the two limiting posts.

[0012] Compared with existing technologies, a split cold heading die using the above-mentioned technical solution has the following advantages:

[0013] 1. During use, when the operator needs to install the forming mold inside the main mold, first place the forming mold inside the main mold, aligning the fixing groove with the fixing hole. Then, insert the fixing post through the fixing hole and slide it into the fixing groove. Finally, connect the first bolt to the threaded groove to complete the installation of the forming mold. Conversely, when the operator needs to disassemble the forming mold, rotate the first bolt again, then pull out the fixing post away from the inside of the fixing groove, and the forming mold can be removed from the main mold. The coordinated use of the fixing groove, fixing hole, fixing plate, fixing post, threaded groove, first threaded hole, and first bolt facilitates the operator's assembly and disassembly of the forming mold, improving its stability during stamping. Compared to directly installing the forming mold inside the main mold via threads, it reduces the risk of thread damage, avoids thread friction and jamming problems, and extends the service life of the mold.

[0014] Second, during use, the cooperation between the positioning rod and the positioning groove facilitates the positioning of the forming mold by the operator, ensuring that the fixing groove and the fixing hole correspond, thus ensuring accurate alignment of the forming mold during installation and improving the convenience of installation. The bearing ring provides support after the forming mold is installed inside the main mold, effectively distributing the punching force and extending the service life of the fixing column.

[0015] Thirdly, during use, the combination of anti-slip rings and anti-slip patterns effectively improves the stability of the forming die inside the main die, increases friction, and thus enhances safety and precision during the stamping process. The use of the mounting plate, second bolt, and nut facilitates the disassembly and assembly of the main die, making maintenance or replacement easier. The use of the limiting post and limiting sleeve allows for precise positioning during main die installation, ensuring alignment of the mounting hole and the second threaded hole, improving stability and ease of installation.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a separable cold heading mold includes a shaping mold 1, which is detachably disposed inside a main mold 2. The shaping mold 1 has two fixing grooves 3 on its left and right sides respectively. The main mold 2 has two fixing holes 4 on its left and right sides respectively. The main mold 2 has two fixing plates 5 detachably disposed on its left and right sides respectively. The two fixing plates 5 have two fixing posts 6 fixed on their inner sides respectively. The two fixing posts 6 are slidably inserted into the two fixing holes 4 and the two fixing grooves 3 respectively. The main mold 2 has threaded grooves 7 on its left and right sides respectively. The two fixing plates 5 have first threaded holes 8 on one side respectively. The two first threaded holes 8 are threaded with first bolts 9 respectively. The threaded ends of the two first bolts 9 are threadedly connected to the inside of the two threaded grooves 7 respectively.

[0023] In use, when the operator needs to install the shaping mold 1 inside the main mold 2, first place the shaping mold 1 inside the main mold 2, aligning the fixing groove 3 with the fixing hole 4. Then, insert the fixing post 6 through the fixing hole 4 and slide it into the fixing groove 3. Finally, connect the first bolt 9 to the threaded groove 7 to complete the installation of the shaping mold 1. Conversely, when the operator needs to disassemble the shaping mold 1, rotate the first bolt 9 again, then pull out the fixing post 6 away from the inside of the fixing groove 3, and the shaping mold 1 can be removed from the main mold 2. The coordinated use of the fixing groove 3, fixing hole 4, fixing plate 5, fixing post 6, threaded groove 7, first threaded hole 8, and first bolt 9 facilitates the operator's assembly and disassembly of the shaping mold 1, improving its stability during stamping. Compared to directly installing the shaping mold 1 into the main mold 2 via threads, it reduces the risk of thread damage, avoids thread friction and jamming problems, and extends the service life of the mold.

[0024] like Figures 1-4 As shown, positioning rods 10 are fixed on the front and rear sides of the shaping mold 1, and positioning grooves 11 are opened on the front and rear sides of the inner wall of the main mold 2, with the two positioning grooves 11 respectively positioning the two positioning rods 10.

[0025] In use, the positioning rod 10 and the positioning groove 11 work together to help the workers to position the mold 1 during installation, so that the fixing groove 3 corresponds to the fixing hole 4, ensuring that the mold 1 can be accurately aligned during installation and improving the convenience of installing the mold 1.

[0026] like Figures 1-4 As shown, a bearing ring 12 is fixed to the inner wall of the main mold 2, and an anti-slip ring 13 is fixed to the top surface of the bearing ring 12. The top surface of the anti-slip ring 13 is provided with anti-slip texture 14.

[0027] During use, the bearing ring 12 provides support for the operator to install the forming mold 1 inside the main mold 2, effectively distributing the stamping pressure and increasing the service life of the fixing column 6. The combined use of the anti-slip ring 13 and the anti-slip texture 14 effectively improves the stability of the forming mold 1 inside the main mold 2, increases friction, and thus improves the safety and precision of the stamping process.

[0028] like Figures 1-4As shown, a base 15 is detachably mounted on the outer wall of the main mold 2. Two second threaded holes 16 are opened on the top surface of the base 15. Mounting plates 17 are fixed on the left and right sides of the outer wall of the main mold 2, respectively. Mounting holes 18 are opened on the top surfaces of the two mounting plates 17. Second bolts 19 are threaded into the two second threaded holes 16, respectively. The two second bolts 19 are slidably inserted into the two mounting holes 18, respectively. Nuts 20 are threadedly connected to the threaded ends of the two second bolts 19. Two limiting posts 21 are fixed on the top surface of the base 15. Limit sleeves 22 are fixed on the front and rear sides of the outer wall of the main mold 2, respectively. The two limiting sleeves 22 are slidably mounted on the two limiting posts 21.

[0029] During use, the mounting plate 17, the second bolt 19, and the nut 20 facilitate the disassembly and assembly of the main mold 2, making it easier to maintain or replace it. The use of the limiting post 21 and the limiting sleeve 22 helps to limit the movement of the main mold 2 during installation, ensuring alignment between the mounting hole 18 and the second threaded hole 16, thus improving stability and convenience during installation.
