Technical Field

[0001] This utility model relates to the field of cold heading, specifically to a cold heading machine mold box. Background Technology

[0002] Existing cold heading machine mold boxes are generally composed of a mold body and a mold cover. The mold cover is a whole and is relatively heavy to install. Moreover, there are multiple connection structures between the mold cover and the mold body. If there is a slight deviation in the processing, it will affect the overall connection between the mold cover and the mold body, making the connection between the mold body and the mold cover not tight enough. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cold heading machine mold box, including a mold body, a mold cover, and several bolts. After the mold cover is installed on the mold body, several equally spaced mold holes are formed between the mold cover and the mold body. The mold cover includes a left cover plate and a right cover plate, and connecting holes are provided on the left cover plate and the right cover plate. Threaded holes are provided on the mold body.

[0004] Preferably, the mold body has a first positioning groove, and the left cover plate and the right cover plate have a second positioning groove. During assembly, the first positioning groove and the second positioning groove are joined together to form a positioning hole between the mold body and the left cover plate, and between the mold body and the right cover plate. A positioning block with a shape that matches the positioning hole is provided in the positioning hole.

[0005] Preferably, the mold cover also includes a middle cover plate. The length of the middle cover plate is less than the distance between the left and right edges of two adjacent mold holes. An installation groove 1 is provided in the middle of the bottom of the left cover plate. A protrusion 1 is provided on the right side of the left cover plate. A notch 1 is provided at the bottom of the protrusion 1. An installation groove 3 is provided in the middle of the bottom of the right cover plate. A protrusion 2 is provided on the left side of the right cover plate. A notch 2 is provided at the bottom of the protrusion 2. Two installation grooves 2 are provided at the bottom of the middle cover plate. The two sides of the bottom of the middle cover plate are higher than the middle, so that the middle cover plate is inverted "mountain" shape. After installation, the left side of the middle cover plate smoothly transitions with the notch 1, and the right side of the middle cover plate smoothly transitions with the notch 2. Four installation grooves 4 are provided on the mold body.

[0006] Preferably, the connecting hole is connected to the second positioning groove, the threaded hole is connected to the first positioning groove, and a vertical through hole is provided on the positioning block.

[0007] Preferably, cooling channels are provided on the mold body and the mold cover.

[0008] Preferably, the side walls of mounting slot 1, mounting slot 2, mounting slot 3 and mounting slot 4 are provided with slots for locking the inner mold.

[0009] The beneficial effects of this utility model are: by disassembling the mold cover structure for installation, it is lighter in weight than a one-piece mold cover, and is easier to move and position during installation; and after the mold cover is disassembled, the impact of deviations and deformations of individual parts on the overall mold cover is reduced, making the overall connection between the mold cover and the mold body more tight.

[0011] Figure 2 This is a structural diagram of the phantom;

[0012] Figure 3 This is a structural diagram of the positioning block. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0014] Please see Figures 1-3 This utility model provides a cold heading machine mold box, including a mold body 1, a left cover plate 21, a right cover plate 22, and a middle cover plate 23. The left cover plate 21, right cover plate 22, and middle cover plate 23 form a mold cover structure, and each of the left cover plate 21, right cover plate 22, and middle cover plate 23 is individually connected to the mold body 1 by bolts. Disassembling the mold cover structure for installation results in a lighter weight compared to a single mold cover, facilitating movement and positioning during installation. Furthermore, after the mold cover is disassembled, the impact of deviations or deformations in individual parts on the overall mold cover is reduced, resulting in a tighter connection between the mold cover and the mold body 1. It should be understood that the mold cover can also consist only of the left cover plate 21 and right cover plate 22, or it can be divided into more parts, depending on process requirements, and is not a limitation of this patent application.

[0015] Furthermore, the bottom of the left cover plate 21, right cover plate 22, and middle cover plate 23 are provided with second positioning grooves 32, and the connection between the mold body 1 and the cover plate is provided with a first positioning groove 31. During installation, the positioning block 8 is placed into the first positioning groove 31. After the positioning block 8 is placed into the first positioning groove 31, part of it protrudes from the connecting hole. After the positioning block 8 is placed, the left cover plate 21, right cover plate 22, and middle cover plate 23 are then installed. The second positioning groove 32 is aligned with the protruding part of the positioning block 8, so that the positioning block 8 positions the left cover plate 21, the right cover plate 22 and the middle cover plate 23, and positions the left cover plate 21, the right cover plate 22 and the middle cover plate 23; in this way, when the bolts are fixed, the left cover plate 21, the right cover plate 22 and the middle cover plate 23 will not deviate, improving the installation accuracy of the left cover plate 21, the right cover plate 22 and the middle cover plate 23, that is, the mold cover and the mold body 1, and making the connection between the mold cover and the mold body 1 tighter.

[0016] Furthermore, the length of the middle cover plate 23 is less than the distance between the left and right edges of two adjacent mold holes. A mounting groove 41 is provided in the middle of the bottom of the left cover plate 21. A protrusion 51 is provided on the right side of the left cover plate 21, and a notch 61 is provided at the bottom of the protrusion 51. A mounting groove 43 is provided in the middle of the bottom of the right cover plate 22. A protrusion 52 is provided on the left side of the right cover plate 22, and a notch 62 is provided at the bottom of the protrusion 52. Two mounting grooves 42 are provided at the bottom of the middle cover plate 23. The two sides of the middle cover plate 23 are higher than the middle, making it resemble an inverted "mountain" shape. After installation, the left side of the middle cover plate 23 smoothly transitions to notch 1 61, and the right side smoothly transitions to notch 2 62. Four mounting slots 44 are provided on the mold body 1. The protrusion 51 increases the width of the right side of the left cover plate 21, allowing for larger connecting holes and thus enabling the use of larger bolts to more firmly connect the left cover plate 21 to the mold body 1. The protrusion 2 on the right cover plate 22 serves a similar purpose. The shorter design of the middle cover plate 23 ensures equidistant arrangement of the mold holes. After installation, the left and right cover plates 21 and 22 can position the middle cover plate 23 from both sides, thus compensating for the relatively weak connection strength of the middle cover plate 23.

[0017] Furthermore, the connecting hole is connected to the second positioning groove 32, the threaded hole is connected to the first positioning groove 31, and the positioning block 8 is provided with a vertical through hole 81. During installation, the bolt is passed through the vertical through hole 81 to assist in positioning the positioning block 8, thereby preventing the positioning block 8 from shifting and making the structure more robust.

[0018] Furthermore, cooling channels are provided on the mold body 1 and the mold cover. When the blank needs to be heated and processed, the cooling channels are connected to the cooling system to assist the mold box in cooling down.

[0019] Furthermore, mounting slots 41, 42, 43 and 44 are provided with slots 7 on their side walls for securing the inner mold, facilitating the installation of the inner mold.

[0020] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
