[0017] Figure 1 Figure 2 , Figure 3The present invention includes a mold body 9 identification limit device 1, the mold body 9 is provided with an installation groove adapted to the identification limit device 1, two threaded holes extending into the mold body 9 and a plurality of identification head holes 3 for positioning and installing the identification head 4 are provided on both sides of the bottom of the installation groove, the identification limit device 1 is provided with a screw limit hole 2 corresponding to the position of the two threaded holes, the identification limit device 1 is detachably installed on the mold body 9 through the two screw limit holes 2 and the two fastening screws 7 in the corresponding threaded holes, the identification head hole 3 is step-shaped, including a small step portion matching the small step cylindrical surface of the identification head 4, and a large step portion connected to the lower end of the small step portion and matching the large step cylindrical surface of the identification head 4, the upper end of the small step portion is flush with the upper surface of the identification limit device 1, and the lower end of the large step portion is flush with the lower surface of the identification limit device 1, and the large step portion is provided with a matching plane that cooperates with the two anti-rotation cutting surfaces to prevent rotation, which can not only ensure the rapid switching of the identification head, but also limit the installation direction of the identification head. The identification surface of the identification header 4 is flush with the mold cavity surface of the mold body 9.

[0018] The screw limiting hole 3 is a stepped hole, including a large stepped hole matching the screw head of the fastening screw 7, and a small stepped hole connected to the lower end of the large stepped hole matching the screw rod of the fastening screw 7; the small stepped hole is a threaded hole installed in cooperation with the screw rod of the fastening screw 7; the fastening screw 7 is a slotted cylindrical head screw.

[0019] Figure 4 In the figure, the outer surface of the identification head 4 is a stepped cylindrical surface, including a small step cylindrical surface and a large step cylindrical surface connected to the lower end of the small step cylindrical surface. The large step cylindrical surface is provided with two left-right symmetrical anti-rotation cutting surfaces. The distance between the two anti-rotation cutting surfaces is greater than the diameter of the small step cylindrical surface. After the identification head 4 is inserted into the identification limiting device 1, the identification head 4 cannot rotate. At this time, as long as the direction of the identification head is specified, it can be ensured that the identification is neat and correct. The advantage of the two cutting surfaces is that the matching part between the identification device and the identification head is easy to process, and at the same time, the two cutting surfaces are better limited.

[0020] Figure 5 Among them, the identification surface 6 has an identification word one, and the direction of the identification word one is parallel to the direction of the milled anti-rotation cutting surface.

[0021] Figure 6 In the figure, there is a second logo character on the back side 5 of the logo character head, and the content and direction of the second logo character are consistent with the first logo character on the logo surface 6, so as to ensure that the order and direction of the logo character heads are correct when the logo character heads are assembled.
