Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0023] A novel internal positioning mold according to a preferred embodiment of the present utility model, as Figure 2-3 shown, includes an upper mold 10 and a lower mold 20. The lower mold 20 includes a stripping plate 21, a backing plate 22, and a lower mold base 23 arranged in sequence from top to bottom. Among them, the upper surface of the stripping plate 21 is provided with a material waiting position for horizontally placing a workpiece 01. An installation groove 211 is arranged within the range of the material waiting position on the upper surface of the stripping plate 21. A positioning column assembly and a locking member 212 for locking and fixing the positioning column assembly in the installation groove 211 are arranged in the installation groove 211.

[0024] This new type of internal positioning die has a simple structure and ingenious design. The positioning post assembly is installed and fixed in the installation groove on the stripper plate through a locking part. When fine-tuning or replacing, only the locking part needs to be removed from the stripper plate, without removing the stripper plate from the lower die. The positioning post assembly can be directly taken out from the installation groove on the stripper plate for debugging on the machine. The operator can operate easily, the disassembly and assembly are convenient, time is saved, and the work efficiency is improved.

[0025] In an embodiment, the positioning post assembly includes an internal positioning insert 213 disposed in the installation groove 211, and a positioning post 214 detachably connected to the internal positioning insert 213; the shape of the installation groove 211 is adapted to the outer contour of the internal positioning insert 213, and the connection between the installation groove 211 and the internal positioning insert 213 is more stable, facilitating the positioning of the positioning post assembly; preferably, the installation groove 211 is located at the center position of the waiting material position, facilitating the positioning of the workpiece 01.

[0026] Furthermore, a positioning groove 215 for the vertical insertion of the positioning post 214 is provided in the middle of the internal positioning insert 213; when the positioning post assembly is assembled in place, the upper surface of the positioning post 214 protrudes from the upper surface of the stripper plate 21; the peripheral side walls of the positioning groove 215 are all in contact with the outer surface of the positioning post 214, and the positioning post 214 will not shift left and right or back and forth, facilitating the preliminary positioning of the positioning post 214.

[0027] Furthermore, the positioning post 214 and the internal positioning insert 213 are connected and separated through a pin member 216, which is convenient for disassembly and assembly and has a simple structure.

[0028] Furthermore, a first through hole 217 for the pin member 216 to pass through is horizontally penetrated on the positioning post 214; optionally, the first through hole 217 is located in the middle of the positioning post 214; on the opposite side walls of the positioning groove 215 of the internal positioning insert 213, second through holes (not shown in the figure) corresponding to both ends of the first through hole 217 and for the pin member 216 to be inserted are respectively provided; the pin member can be a pin post in the prior art; during assembly, first vertically insert the positioning post 214 into the positioning groove 215 on the internal positioning insert 213, and make the first channel 217 correspond to and communicate with the second through hole (not shown in the figure), and then the positioning post 214 can be fixedly installed in the internal positioning insert 213 by passing the pin member 216 through the first through hole 217 and the second through hole (not shown in the figure). When disassembling, only by using an external ejector pin to eject the pin member 216 can the positioning post 214 be separated from the internal positioning insert 213. The disassembly is convenient, facilitating subsequent replacement of positioning posts with different heights for positioning debugging or replacement of new positioning posts.

[0029] Furthermore, the height of the inner positioning insert 213 is less than the depth of the mounting groove 211; the locking member 212 is located between the upper surface of the inner positioning insert 213 and the upper surface of the stripper plate 21, and fixes the inner positioning insert 213 in the mounting groove 211. Hiding the locking member 212 in the mounting groove 211 can avoid affecting the product positioning.

[0030] Furthermore, the locking member 212 includes a stop screw horizontally arranged on one side of the positioning post 214; one end of the stop screw is threadedly connected to the stripper plate 21, and the side wall of the other end abuts against the upper surface of the inner positioning insert 213; the stop screw and the positioning post assembly are arranged vertically, which is not only convenient for the operator to operate, but also reduces the area of the mounting groove in the horizontal direction, making reasonable use of space; the structure is stable.

[0031] Optionally, the length of the connection between the stop screw and the stripper plate 21 is greater than the length of the contact between the stop screw and the inner positioning insert 213, which ensures the connection strength between the stop screw and the stripper plate 21, and based on the lever principle, enables the stop screw to apply sufficient pressing force to the inner positioning insert, and can prevent the inner positioning insert from disengaging from the mounting groove.

[0032] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
