[0045] It should be noted that the length of the positioning member 2-4 is less than the length of the vehicle floor material, the width of the top side of the positioning member 2-4 is adapted to the width of the inner side of the vehicle floor material, and both sides of the positioning member in the width direction are provided with inclined surfaces inclined downward to adapt to the vehicle floor material, refer to Figure 5 As shown, the middle part of the positioning member is a trapezoidal section 2-4-2, a rectangular section is arranged on the lower side of the positioning member trapezoidal section as the second rectangular section 2-4-3, and a rectangular section is arranged on the upper side of the trapezoidal section as the first rectangular section 2-4-1. The width of the second rectangular section is greater than the width of the first rectangular section, and the height of the second rectangular section 2-4-2 is greater than the height 2-4-1 of the first rectangular section, so that a positioning groove 2-6 is formed between the positioning member 2-4 and the clamping member for clamping the L-shaped plate flange, and a convex portion 2-5 is arranged on the top of the positioning member, and a portion of the convex portion is located at the inclined surface of the positioning member.

[0046] In this embodiment, the protrusion 2-5 is specifically a cylindrical protrusion, and the diameter of the protrusion 2-5 is adapted to the width of the groove on the inner side of the vehicle floor material. The diameter of the protrusion is usually less than or equal to the width of the groove on the inner side of the vehicle floor material, so that the protrusion can be inserted into the groove of the vehicle floor material. Because the inner side of the vehicle floor material is provided with two grooves, the protrusions 2-5 are naturally provided on both sides of the top of the positioning member 2-4;

[0047] At least two convex portions 2-5 are arranged along the length direction of the positioning member, and a distance is set between two adjacent convex portions. Convex portions are arranged on both sides along the width direction of the top surface of the positioning member.

In the present embodiment, according to the requirements of the actual slot-type opening, the punch 1-4 is provided with two sections along the length direction of the punch base 1-1. The two sections of the punch can be connected by a connecting plate, or the two sections of the punch 1-4 are not connected. When the connecting plate connects the two sections of the punch, the connecting plate is shorter than the punch 1-4. The length of the punch 1-4 is the same as the length of the slot-type opening. The lengths of the two sections of the punch 1-4 can be the same or different, which is determined according to actual needs.

[0057] It is easy to understand that in order to effectively guide the mold during the working process, the punch base 1-1 is provided with a plurality of guide segments 1-3, the outer diameter of the guide segment beyond the punch base 1-1 is larger than the outer diameter of the portion connected with the punch base, the guide segment 1-3 is provided with a guide hole for matching with the die box, the pressing piece is provided beyond the guide segment, and the diameter of the guide hole is larger than the outer diameter of the guide column;

Correspondingly, two guide columns are arranged on the same side of the positioning member in the die base, and the positions of the guide columns 2-3 correspond one to one with the positions of the guide sections. In other examples, the guide columns 2-3 can be arranged at the diagonal positions of the positioning member, or the guide columns can also be arranged at the four corners of the die base.

[0059] It is easy to understand that a punch fixing plate 1-2 is set on the side of the punch base 1-1 facing the die, the width of the punch fixing plate 1-2 is smaller than the width of the punch base, the punch fixing plate 1-2 is located between the guide sections on both sides, the punch fixing plate 1-2 is mainly used to fix the punch 1-4, one end of the punch is fixed in the punch fixing plate, the punch fixing plate and the punch base fit effectively to ensure the service life of the punch, and fasteners such as countersunk screws fasten the punch base and one end of the punch 1-4.

[0060] The mold provided in this embodiment realizes punching of vehicle floor materials through cooperation with the convex mold, and the concave mold is provided with a positioning piece and a clamping piece. The positioning piece utilizes the characteristic of providing a groove on the inner side of the vehicle floor material, and the convex portion provided on the positioning piece can effectively position the vehicle floor material. A clamping piece is provided on one side of the positioning piece, and one side of a part of the vehicle floor material can be clamped between the clamping piece and the positioning piece. In this way, not only can the flat plate be punched, but also the L-shaped vehicle floor material can be punched without replacing the punching mold, thereby solving the punching needs of various vehicle floor materials and the problems of frequent mold changing and debugging, and improving the punching and material cutting efficiency.
