[0025] Please see Figure 1-5 A simple mold for slotting aluminum plates for hairdressing includes a lower mold base 2, with a lower template 3 connected to the top wall of the lower mold base 2. The lower template 3 has a punching space 31 extending through its upper and lower surfaces. A punch seat 4 is movably disposed within the punching space 31. Aluminum plate positioning grooves 32 are respectively formed on both sides of the punching space 31 on the top wall of the lower template 3 for placing double-layer aluminum plates 1. The bottom walls of the two opposing aluminum plate positioning grooves 32 each have notched cutting edges 33 that extend through to the bottom wall of the lower template 3 and communicate with the punching space 31. A punch 5 extending above the two notched cutting edges 33 is inserted into the punch seat 4. The punch 5, in conjunction with the notched cutting edges 33, slots the double-layer aluminum plate 1.

[0026] Please see Figure 2-4 In this embodiment, one end of the aluminum plate positioning groove 32 extends through the side wall of the lower template 3, and the other end communicates with the stamping space 31. The width of the aluminum plate positioning groove 32 is adapted to the width of the double-layer aluminum plate 1 to facilitate positioning of the double-layer aluminum plate 1. The top opening of the aluminum plate positioning groove 32 is open to facilitate the placement and removal of the double-layer aluminum plate 1. The groove length direction of the aluminum plate positioning groove 32 is perpendicular to the hole length direction of the stamping space 31 so that the punch 5 can vertically stamp the double-layer aluminum plate 1, thereby ensuring the stamping quality of the product.

[0027] Please see Figure 2 as well as Figure 5 When slotting the lower plate 11 of the double-layer aluminum plate 1, the double-layer aluminum plate 1 to be processed is first placed in the aluminum plate positioning groove 32 for positioning. Then, the double-layer aluminum plate 1 is pushed horizontally towards the punch 5 so that the lower plate 11 of the double-layer aluminum plate 1 is inserted between the punch 5 and the notching edge 33. When the punch 5 is fully inserted into the interior of the double-layer aluminum plate 1, the punch seat 4 is pressed down. The punch 5, which moves down with the punch seat 4, can cooperate with the notching edge 33 to punch and slot the lower plate 11 of the double-layer aluminum plate 1. Its structure is simple, and there is no need to use a large-volume hydraulic machine tool with high cost, so the operating cost is low. There is no need to perform complex positioning and fixing of the double-layer aluminum plate 1. Only a gentle push is needed to perform punching and slotting, which is convenient and practical. There is no need for complex unloading. After slotting, the product can be directly pulled out and taken away, which has high processing efficiency.

[0028] Please see Figure 4-5 The lower die base 2 has a chip removal hole 21 that passes through the upper and lower parts of the notched cutting edge 33. The chip removal hole 21 is coaxially arranged with the notched cutting edge 33. The waste material formed by the punch 5 pressing the double-layer aluminum plate 1 is discharged through the notched cutting edge 33 and the chip removal hole 21, so as to avoid the waste material accumulating in the notched cutting edge 33.

[0029] Please see Figure 4-5 The punch holder 4 has horizontal mounting holes 41 penetrating its two side walls. The length direction of the mounting holes 41 is the same as the length direction of the aluminum plate positioning groove 32. The punch 5 is inserted into the mounting holes 41, with both ends of the punch 5 extending out of the mounting holes 41. The punch holder 4 has horizontal positioning holes 42 penetrating its two side walls. The punch 5 has through holes 51 penetrating its two side walls. The length directions of the through holes 51 and the positioning holes 42 are perpendicular to the length direction of the mounting holes 41. Positioning pins 6 are inserted into the through holes 51 and the positioning holes 42.

[0030] When installing punch 5, first insert punch 5 into mounting hole 41, then align punch 5's through hole 51 with punch base 4's positioning hole 42, and then pass positioning pin 6 through through hole 51 and positioning hole 42 to fix punch 5 on punch base 4. Positioning pin 6 serves to position punch 5, facilitating accurate punching of double-layer aluminum plate 1; at the same time, the through hole 51, positioning hole 42, and positioning pin 6 facilitate disassembly, assembly, and replacement of punch 5, thereby improving work efficiency.

[0031] In this embodiment, each aluminum plate positioning groove 32 is a stamping station. The punch 5 has stamping portions 52 formed at both ends. The two stamping portions 52 correspond vertically to the corresponding notch cutters 33 and are adapted to the shape of the U-shaped groove 12 of the double-layer aluminum plate 1. When one of the stamping portions 52 of the punch 5 wears out, the double-layer aluminum plate 1 can be moved to the aluminum plate positioning groove 32 corresponding to the other stamping portion 52, so that the stamping operation can continue without replacing the punch 5, which is convenient and quick. Stamping operations can also be performed at two stamping stations simultaneously, resulting in higher processing efficiency.

[0032] Please see Figure 4-5 The top wall of the punch holder 4 has a locking hole 43 that passes through its upper and lower surfaces. The punch holder 4 is connected and fixed to the upper end of the external machine tool through the locking hole 43, so that the external machine tool can drive the punch holder 4 to rise and fall, thereby realizing the stamping action.

[0033] Please see Figure 4-5 The lower die holder 2 has a receiving groove 22 on its top surface that communicates with the stamping space 31. The punch holder 4 has a limiting groove 44 on its bottom wall that is vertically opposite to the receiving groove 22. The receiving groove 22 and the limiting groove 44 contain an elastic reset structure 7 for driving the punch holder 4 to reset upward. The elastic reset structure 7 includes an equalizing screw 71, an equalizing sleeve 72, and a spring 73. The bottom of the receiving groove 22 has a shaft hole 23 that extends to the bottom wall of the lower die holder 2. The top end of the equalizing screw 71 passes upward through the shaft hole 23, the receiving groove 22, and the limiting groove 44 and is threaded into the locking hole 43. The equalizing sleeve 72 is fitted on the outer circumferential surface of the equalizing screw 71. The spring 73 is fitted on the outer circumferential surface of the equalizing sleeve 72 and is located in the receiving groove 22 and the limiting groove 44. The top end of the spring 73 abuts against the top wall of the limiting groove 44, and the bottom end of the spring 73 abuts against the bottom wall of the receiving groove 22.

[0034] In this embodiment, the top end of the equal height sleeve 72 abuts against the top wall of the limiting groove 44, and the equal height sleeve 72 extends downward to the bottom end of the bottom wall of the lower mold base 2 to form an outwardly protruding ring 74, the top surface of the protruding ring 74 abuts against the bottom wall of the lower mold base 2.

[0035] When the punch holder 4 drives the punch 5 to press down to open the slot, the spring 73 is gradually compressed. After the punch 5 completes the slotting operation, the punch holder 4 bounces up and resets under the action of the spring 73 until the convex ring 74 of the equal height sleeve 72 presses against the bottom wall of the lower die holder 2. At this time, the punching part 52 of the punch 5 is just above the notching edge 33, and the punching part 52 and the bottom wall of the aluminum plate positioning groove 32 are just enough for the lower plate 11 of the double-layer aluminum plate 1 to be inserted. Therefore, the convex ring 74 of the equal height sleeve 72 has the function of positioning the punch 5, which enables the punch 5 to accurately punch the double-layer aluminum plate 1 after each reset, without the need to readjust the punch 5 or the double-layer aluminum plate 1, which helps to improve work efficiency.

[0036] Please see Figure 4 The lower mold base 2 has two opposing feet 8 connected to its bottom wall, and a plurality of foot screws 9 connecting the two feet 8 to the lower mold base 2; the lower mold base 2 and the lower template 3 are connected by a plurality of lower template screws 10. In this embodiment, the number of foot screws 9 and lower template screws 10 is four, but this utility model does not limit the number of foot screws 9 and lower template screws 10, and can set other numbers according to actual needs.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
