Specific embodiments
[0027] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.
[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.
[0030] The terms "comprising" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0031] One of the preferred embodiments of the present application is as Figures 1 to 8 shown, a mold with an anti-reverse design includes a lower die 2 and an anti-reverse part 24. The anti-reverse part 24 is installed at a non-central line position in the length direction of the lower die 2. A processing area 20 is provided on the lower die 2, and a part of the anti-reverse part 24 protrudes from the processing area 20. A perforation 33 corresponding to the anti-reverse part 24 is provided on the blank 3.
[0032] It should be noted that when a normal mold is operating, the upper mold of the mold presses down on the blank 3 in the processing area 20 of the lower mold 2 to achieve forming. However, when the two ends of the blank 3 are extremely similar, the staff may accidentally cause the blank 3 to be placed in the wrong direction when not paying attention, which will result in unqualified processed products, thereby increasing the production cost, wasting the blank 3, and wasting working time.
[0033] Therefore, in this embodiment, an anti-reversal member 24 is provided on the lower mold 2, and a perforation 33 corresponding to the position is provided on the blank 3. Only when the perforation 33 on the blank 3 passes through the anti-reversal member 24 correspondingly, the blank 3 can be correctly placed on the lower mold 2 and at the same time connected to the positioning member provided on the lower mold 2, waiting for the upper mold to press down for processing.
[0034] In this embodiment, as Figure 1 、 2 、shown in Figure 3, the lower mold 2 is fixedly installed on the frame 1 through a threaded structure. The staff first correctly places the blank 3 on the lower mold 2, and then starts the upper mold of the mold to process qualified products. However, in a long-term working environment, the staff may place the blank 3 in the wrong direction due to inattentiveness. In order to improve the processing qualification rate of the blank 3, an anti-reversal member 24 is provided on the lower mold 2 in this application.
[0035] It can be understood that a processing area 20 is provided on the lower mold 2, and the blank 3 is placed in the processing area 20 waiting for the upper mold to press down for processing. Therefore, when the anti-reversal member 24 is installed on the lower mold 2, part of it needs to protrude from the processing area 20. At the same time, a perforation 33 corresponding to the position of the anti-reversal member 24 is provided on the blank 3. Only when the part of the anti-reversal member 24 protruding from the processing area 20 passes through the perforation 33, the blank 3 is correctly placed in the processing area 20. Otherwise, the blank 3 is placed in the wrong direction, which will cause the blank 3 to be pierced by the part of the anti-reversal member 24 protruding from the processing area 20, thereby wasting the blank 3.
[0036] It can also be understood that the work tasks of the staff are usually relatively busy. Generally speaking, the structural shape of the anti-reversal member 24 can be set in any shape. However, in the actual operation process, if the anti-reversal member 24 is set in any polygon or irregular shape, the staff may need to spend time aligning the perforation 33 with the side line of the anti-reversal member 24 when placing the blank 3. At the same time, the upper mold also needs to be drilled according to the shape of the anti-reversal member 24 so that the upper mold will not touch the anti-reversal member 24 when pressing down. Although such a structural setting of the anti-reversal member 24 increases the production qualification rate of the blank 3, it also increases the operation burden of the staff to a certain extent and reduces the processing efficiency of the blank 3 to a certain extent. Therefore, in this application, the shape of the anti-reversal member 24 is set as a cylinder. The surface of the cylinder is smooth and will not cause obstacles when the operator places the blank 3, which can better meet the current usage needs of the staff.
[0037] In this embodiment, as can be obtained from the above, in order for the staff to conveniently place the blank 3 correctly in the processing area 20, the anti-reversal member 24 of the present application is arranged in a cylindrical structure. However, in actual operation by the staff, the anti-reversal member 24 in the cylindrical structure will still cause a certain degree of obstruction to the placement of the blank 3 to a certain extent. The top of the anti-reversal member 24 is in a circular structure, and its edge is prone to obstructive friction with the perforation 33 on the blank 3, so it is still not convenient for the staff to use and operate.
[0038] Therefore, in this embodiment, as Figure 8 shown, a first protruding section 240 is provided on the top of the anti-reversal member 24 in the cylindrical structure, and the first protruding section 240 is in a conical shape. The conical top enables the staff to easily place the blank 3 in the processing area 20, and its smooth conical side can meet the use requirements of the staff.
[0039] In this embodiment, the function of the anti-reversal member 24 only exists in preventing the blank 3 from being placed in the reverse direction, but it does not have the function of accurately positioning the blank 3 and placing it in the processing area 20.
[0040] Therefore, in this embodiment, as Figure 4 、 5 shown, a positioning member is further provided on the lower die 2, and a positioning hole corresponding to the position thereof is provided on the blank 3. When the staff places the blank 3 in the processing area 20, first, the perforation 33 needs to be aligned with the anti-reversal member 24, and then the positioning hole and the positioning member are aligned in position, so that the blank 3 can be correctly placed in the processing area 20.
[0041] It should be known that in this embodiment, there are various specific setting methods for the numbers of both the positioning member and the anti-reversal member 24, including but not limited to the following two.
[0042] Method 1: There are multiple positioning members and multiple anti-reversal members 24. The positioning members are arranged at equal intervals along the center line of the length direction of the lower die 2, and the anti-reversal members 24 are respectively arranged on the sides of the positioning members.
[0043] Method 2: There are multiple positioning members and one anti-reversal member 24. The positioning members are arranged at equal intervals along the center line of the length direction of the lower die 2, and the anti-reversal member 24 is arranged on the side of one of the positioning members.
[0044] It should be known that the above two setting methods can both meet the requirements of the present application, and those skilled in the art can select according to actual needs; in this embodiment, the above Method 2 is preferably adopted.
[0045] It can be understood that, due to the limited area of the processing area 20, if the number of anti-reversal members 24 is too large, it is inconvenient to place the blank 3. And if the number of anti-reversal members 24 is too large, even if the top of the anti-reversal member 24 is provided with a first protruding section 240, it is not beneficial to the placement of the blank 3 and is inconvenient for the staff to place the blank 3.
[0046] Therefore, in this embodiment, as Figure 4 , 5 shown, the lower die 2 is further provided with a first positioning member 21, a second positioning member 22 and a third positioning member 23. The blank 3 is further provided with a first positioning hole 30, a second positioning hole 31 and a third positioning hole 32. The anti-reversal member 24 is arranged on the side of the second positioning member 22. First, the staff aligns the perforation 33 with the anti-reversal member 24, and then aligns the first positioning hole 30, the second positioning hole 31 and the third positioning hole 32 on the blank 3 with the first positioning member 21, the second positioning member 22 and the third positioning member 23, so that the blank 3 can be correctly placed and positioned in the processing area 20 for the upper die to press down for processing.
[0047] It should be known that the structural setting of the positioning member also affects the operation process of the staff. Therefore, for the actual operation of the staff to be easy. As Figure 8 shown, the first positioning member 21, the second positioning member 22 and the third positioning member 23 are all arranged in a cylindrical structure, and the top is provided with a second protruding section 230 for the staff to operate.
[0048] In this embodiment, as can be obtained from the above, the blank 3 can be correctly placed in the installation area 20 through the anti-reversal member 24, the first positioning member 21, the second positioning member 22 and the third positioning member 23. However, there are various ways to set the height between the positioning member and the anti-reversal member 24. One: the height of the anti-reversal member 24 is higher than the height of the positioning member; two: the height of the anti-reversal member 24 is flush with the height of the positioning member; three: the height of the anti-reversal member 24 is lower than the height of the positioning member.
[0049] It can be understood that there are multiple positioning members. If the height of the anti-reversal member 24 is lower than the height of the positioning member, it is very time-consuming for the staff to take out the blank 3 after accidentally placing it in the wrong direction, which affects the processing efficiency. Therefore, it is not advisable that the height of the anti-reversal member 24 is lower than the height of the positioning member. Therefore, the height of the anti-reversal member 24 is flush with or higher than the height of the positioning member.
[0050] It can also be understood that in this embodiment, it is more preferable that the height of the anti-reverse member 24 is higher than that of the positioning member both when the anti-reverse member 24 is flush with the positioning member and when the anti-reverse member 24 is higher than the positioning member. Specifically, if the height of the anti-reverse member 24 is higher than that of the positioning member, the staff can first determine whether the blank 3 is placed correctly when placing it. When it is confirmed that the position of the blank 3 is correct, the staff can quickly place the blank 3 into the processing area 20. At the same time, the height of the anti-reverse member 24 cannot be set too high. If the height of the anti-reverse member 24 is set too high, although it can be quickly confirmed whether the blank 3 is anti-reversed, the too-high anti-reverse member 24 will rub against its perforation 33 during the placement process of the blank 3, thereby affecting the corresponding cooperation between the positioning hole on the blank 3 and the positioning member, and slowing down the placement speed of the blank 3. Therefore, the height of the anti-reverse member 24 needs to be limited in this embodiment.
[0051] Therefore, in this embodiment, as Figure 4 shown, it is defined that the height of the anti-reverse member 24 is 5% - 20% higher than that of the positioning member.
[0052] At the same time, in this embodiment, the function of the anti-reverse member 24 in the mold is only to limit the blank 3 from being placed in the wrong direction, and the function of the positioning member is to position the blank 3. In order to make the fixation of the positioning member to the blank 3 more stable. Therefore, in this embodiment, as Figure 4 shown, it is defined that the diameter of the positioning member is 5% - 10% larger than the diameter of the anti-reverse member 24.
[0053] In this embodiment, as Figure 6 、 7 shown, in order to enable the blank 3 to be placed more stably in the processing area 20, the two ends of the processing area 20 are provided with a first fixing portion 200 and a second fixing portion 201. The first fixing portion 200 and the second fixing portion 201 can fix the two ends of the blank 3 to fix the entire blank 3 so that it can be placed more stably in the processing area 20. And in this application, in order to enable the first positioning member 21, the second positioning member 22, the third positioning member 23 and the anti-reverse member 24 to be stably arranged on the lower mold 2, a plurality of connecting holes 202 are provided on the lower mold 2, and the first positioning member 21, the second positioning member 22, the third positioning member 23 and the anti-reverse member 24 are fixedly installed in the connecting holes 202, so that the anti-reverse member 24 and the positioning member can play their roles stably.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present application.
