In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0035] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0036] The present application provides an upper mold. It should be noted that the upper mold herein can refer to a compression mold, a stamping mold, a die-casting mold, and the like. For example, based on the molding material, the upper mold herein can be a metal mold upper mold, such as a stamping mold, a plastic mold upper mold, such as a compression mold, or a special mold upper mold, such as a die-casting mold. Furthermore, the upper mold requires auxiliary components, such as a mold base, a mold frame, a mold core, and a workpiece ejection device. These components are generally manufactured to be universal.

[0037] It should be noted that in the embodiments of this application, the material of the upper mold is not further limited. For example, upper mold materials include steel (such as cold work die steel, hot work die steel, plastic mold steel, etc.), aluminum alloy, and cast iron. These materials have advantages such as high hardness, good heat resistance, and high strength, and can meet the processing requirements of different upper molds.

[0038] The upper mold provided in the embodiment of the present application is specifically used for manufacturing the inner panel of a vehicle door.

[0039] For example, some upper dies are stamping dies made of steel. Stamping dies offer high precision, high efficiency, material conservation, and adaptability. Parts produced using these dies are precise in size and consistent in shape, meeting the manufacturing needs of complex shapes and high-precision products. Furthermore, stamping dies can significantly improve production efficiency and reduce costs, making them an indispensable tool in the manufacturing industry.

[0040] On this basis, refer to Figure 1 、 Figure 3 and Figure 6 The embodiment of the present application also provides an upper mold 100, including an upper mold base 1, a pressure plate 2, a working side pin 5, a hook 3 and a backrest 4.

[0041] In order to better illustrate the upper mold 100 provided in the embodiment of the present application, refer to Figure 2 、 Figure 4 and Figure 6 The pressing plate 2 is arranged in the upper die holder 1 in a manner that it can be lifted and lowered, for example, along the up and down directions (such as Figure 2 When the upper die 100 is working, the pressing plate 2 presses the workpiece to be processed downward to realize the stamping work.

[0042] Reference Figure 1 and Figure 4 The working side pin 5 is provided on the pressing plate 2 along the first direction (such as Figure 1 The upper mold 100 is adapted to the mold. When the mold is closed, the working side pins 5 ensure that the mold components are properly aligned and tightly closed, thereby preventing the mold from misaligning or shifting during the stamping process. Similarly, when the mold is opened, the working side pins 5 assist in the smooth separation of the mold, maintaining the integrity and stability of the mold and ensuring accuracy and consistency during the movement of the blank holder 2.

[0043] Furthermore, the hook 3 is provided on the upper die base 1, and is used to abut against the pressing plate 2 when the pressing plate 2 falls to the extreme position. When the upper die 100 works normally, the hook 3 separates from the pressing plate 2, and the pressing plate 2 works normally; when the pressing plate 2 falls off, the pressing plate 2 falls to the extreme position, and the hook 3 stops abutting against the pressing plate 2 to prevent the pressing plate 2 from continuing to fall, to prevent the pressing plate 2 from being completely separated from the upper die base 1, to prevent the pressing plate 2 from falling and damaging other objects or injuring people, and to avoid causing safety risks and property losses.

[0044] Furthermore, the hook 3 and the working side pin 5 are located on opposite sides of the blank holder 2, providing ample space for the upper die 100 to arrange the hook 3 and the working side pin 5, thereby increasing the strength of the upper die 100 and ensuring the safety of the upper die 100. The hook 3 is positioned on the blank holder 2 away from the location of the working side pin 5, thus balancing safety performance with ease and feasibility of arrangement.

[0045] The backrest 4 is placed on the upper die base 1 and connected to the hook 3, and is used to abut the hook 3 to prevent it from turning over when it abuts the pressing plate 2. When assembling the upper die 100, the backrest 4 can press the hook 3 and abut it, preventing the hook 3 from turning over when it abuts the pressing plate 2, thereby achieving a tight fit between the backrest 4 and the hook 3 and the upper die base 1, making the assembly of the upper die 100 relatively simple and reliable; when disassembling the upper die 100, the backrest 4 is first removed, then the hook 3 is taken out, and finally the pressing plate 2 can be removed, making the disassembly of the upper die 100 relatively simple and reliable.

[0046] In the upper die 100 provided in the embodiment of the present application, the working side pin 5 is provided on the upper die base 1, and the working side pin 5 is provided on the side wall of the blank pressing plate 2 along the first direction. The hook 3 is provided on the upper die base 1, and the hook 3 and the working side pin 5 are located on opposite sides of the blank pressing plate 2. The backrest 4 is placed on the upper die base 1 and connected to the hook 3, and is used to abut the hook 3 to prevent it from turning over when it abuts the blank pressing plate 2. This allows the upper die 100 to have more space for arranging the hook 3 and the working side pin 5, and the position of the hook 3 on the blank pressing plate 2 avoids the position of the working side pin 5, taking into account both safety performance and layout convenience and feasibility.

[0047] In addition, in the embodiment of the present application, the movement mode of the blank holder 2 is not limited, as long as it can be movably arranged in the blank holder 1 in the vertical direction. For example, a cylinder is provided on the upper die base 1, and the cylinder drives the blank holder 2 to move in the vertical direction.

[0048] In addition, it should be noted that, in the embodiment of the present application, the pressing plate 2 is equivalent to the mold core, and the pressing plate 2 is used to cooperate with the workpiece to be processed to realize the processing and production of the workpiece to be processed.

[0049] In some embodiments of the present application, reference is made to Figure 1 and Figure 5 The upper end of the hook 3 is provided with a first mounting portion 33, which is connected to the upper mold base 1 via a fastener. In this case, the connection between the hook 3 and the upper mold base 1 is relatively simple and reliable, and the hook 3 can be easily removed. In addition, the first mounting portion 33 can be provided at the upper end of the hook body 31 and extend along the second direction toward the side away from the backrest 4, or the first mounting portion 33 can be provided at the upper end of the hook body 31 and extend toward either side of the first direction. A more convenient mounting position can be selected according to the processing and installation steps to meet different operational requirements when assembling the upper mold 100.

[0050] In some embodiments of the present application, reference is made to Figure 1 and Figure 5 The upper end of the backrest 4 is provided with a second mounting portion 41, which is connected to the upper mold base 1 via fasteners. In this case, the connection between the backrest 4 and the upper mold base 1 is relatively simple and reliable, and the backrest 4 can be easily disassembled. In addition, the second mounting portion 41 can be provided at the upper end of the backrest 4 and extend in the second direction toward the side away from the hook 3, or the second mounting portion 41 can be provided at the upper end of the backrest 4 and extend to either side of the first direction. A more convenient mounting position can be selected according to the processing and installation steps to meet different operational requirements when assembling the upper mold 100.

[0051] In the present application, the backrest 4 is connected to the upper die base 1 by screws, and the connection between the hook 3 and the upper die base 1 is relatively simple and reliable.

[0052] In the present application, the first mounting portion 33 is provided at the upper end of the hook body 31 and extends along the second direction toward the side away from the backrest 4, and the second mounting portion 41 is provided at the upper end of the backrest 4 and extends along the second direction toward the side away from the hook 3. The second mounting portion 41 of the backrest 4 and the first mounting portion 33 of the hook 3 in the same hanging hole 12 are arranged in sequence to facilitate the assembly of the hook 3 and the backrest 4.

[0053] Common fasteners include bolts, studs, screws, nuts, washers, pins, rivets, self-tapping screws, weld nails, etc.

[0054] It should be noted that in the embodiments of the present application, the specific form of the fastener is not limited, and can be configured according to the coordination between the hook 3 and the backrest 4 and the upper die base 1. For example, in some embodiments of the present application, the hook 3 and the backrest 4 are connected to the upper die base 1 by screws, and the connection between the hook 3 and the upper die base 1 is relatively simple and reliable, and the connection between the backrest 4 and the upper die base 1 is relatively simple and reliable.

[0055] Further, refer to Figure 2 and Figure 6 In some embodiments of the present application, an avoidance groove 13 is provided on the upper surface of the upper mold base 1, and the first mounting portion 33 and the second mounting portion 41 are both arranged in the avoidance groove 13. The upper surfaces of the first mounting portion 33 and the second mounting portion 41 are not higher than the upper surface of the upper mold base 1, which can avoid the upper surface of the upper mold base 1 being provided with a protruding portion, and avoid the protruding portion from scratching other equipment, components and operators during the assembly and use of the upper mold 100, thereby improving the safety of the upper mold 100.

[0056] In this application, the avoidance groove 13 is arranged on both sides of the hanging hole 12 along the second direction, and the second mounting portion 41 of the backrest 4 and the first mounting portion 33 of the hook 3 in the same hanging hole 12 are arranged in sequence to facilitate the assembly of the hook 3 and the backrest 4.

[0057] In some embodiments of the present application, along the second direction (eg Figure 1 The second direction is shown in the figure), the upper die base 1 is provided with hanging holes 12 at the positions on both sides of the pressing plate 2, and there are two hooks 3 that are respectively passed through the hanging holes 12. The hooks 3 are constructed to abut against the pressing plate 2 when the pressing plate 2 falls beyond the limit position. The first direction, the second direction and the up and down directions are perpendicular to each other. When the upper die 100 is working normally, the hooks 3 are separated from the pressing plate 2, and the pressing plate 2 works normally; when the pressing plate 2 falls off, the pressing plate 2 falls beyond the limit position, and the hooks 3 stop against the pressing plate 2 to prevent the pressing plate 2 from continuing to fall, to prevent the pressing plate 2 from being completely separated from the upper die base 1, to prevent the pressing plate 2 from falling and damaging other objects or injuring people, and to avoid causing safety risks and property losses.

[0058] In some embodiments of the present application, reference is made to Figure 1 and Figure 4 , the backrest 4 is passed through the hanging hole 12, and along the second direction, the backrest 4 and the hook 3 are arranged in sequence, and the hook 3 and the backrest 4 are tightly matched with the hanging hole 12. When assembling the upper mold 100, first install the pressing plate 2 into the upper mold base 1, then pass the hook 3 through the hanging hole 12, and the end surface of the hook 3 close to the pressing plate 2 fits with the pressing plate 2. Finally, insert the backrest 4 into the other areas outside the hook 3 in the hanging hole 12. The backrest 4 can squeeze the hook 3 to achieve a tight fit between the backrest 4 and the hook 3 and the hanging hole 12. The assembly of the upper mold 100 is relatively simple and reliable. When disassembling the upper mold 100, first remove the backrest 4 so that the hook 3 can be adjusted in the hanging hole 12, and then take the hook 3 out of the hanging hole 12. Finally, the pressing plate 2 can be removed. The disassembly of the upper mold 100 is relatively simple and reliable.

[0059] In some embodiments of the present application, reference is made to Figure 1 and Figure 4 The lower surface of the upper die base 1 is provided with a mounting groove 11, and the pressing plate 2 is movably arranged in the mounting groove 11 along the up and down directions. The bottom wall of the mounting groove 11 can limit the pressing plate 2 to prevent the pressing plate 2 from continuously moving upward and prevent the pressing plate 2 from being out of engagement with the upper die base 1.

[0060] Furthermore, the hanging hole 12 passes through the upper die base 1, and the hook 3 includes a hook body 31 and a hanging portion 32 extending toward the pressing plate. The hanging portion 32 is arranged at the lower end of the hook body 31, and the hanging portion 32 is constructed to abut against the pressing plate 2 when the pressing plate 2 falls beyond the limit position. When the upper die 100 works normally, the hanging portion 32 separates from the pressing plate 2, and the pressing plate 2 works normally; when the pressing plate 2 falls off, the pressing plate 2 falls beyond the limit position, and the hanging portion 32 stops abutting against the pressing plate 2, preventing the pressing plate 2 from continuing to fall, preventing the pressing plate 2 from being completely separated from the upper die base 1, preventing the pressing plate 2 from falling and damaging other objects or injuring people, and avoiding safety risks and property losses.

[0061] Further, refer to Figure 1 , along the first direction, the two hooks 3 are arranged at intervals, so that when the pressing plate 2 falls off, when the pressing plate 2 falls beyond the limit position, the hanging part 32 on the hook 3 stops with the pressing plate 2, and the hanging part 32 along the first direction and the second direction can limit the pressing plate 2, further preventing the pressing plate 2 from continuing to fall, preventing the pressing plate 2 from being completely separated from the upper mold base 1, preventing the pressing plate 2 from falling and damaging other objects or injuring people, and avoiding safety risks and property losses.

[0062] In addition, it should be noted that, referring to Figure 4 and Figure 6 , a clearance groove 21 is provided on the pressing plate 2 at a position corresponding to the hook 3. The hanging portion 32 can be avoided. After the upper mold 100 is assembled, the hanging portion 32 can be located in the clearance groove 21, which is convenient for installing the backrest 4.

[0063] Further, refer to Figure 6 In the vertical direction, the distance L1 between the upper surface of the air-avoiding groove 21 and the upper surface of the hanging portion 32 and the vertical movement stroke S of the pressing plate 2 satisfy: 10mm≤L1-S≤20mm.

[0064] It can be understood that the value of the distance L1 between the upper surface of the air avoidance groove 21 and the upper surface of the hanging part 32 minus the movement stroke S of the pressing plate 2 in the up and down directions can be 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm or 20mm.

[0065] The distance L1 between the upper surface of the air-avoiding groove 21 and the upper surface of the hanging part 32 minus the movement stroke S of the pressing plate 2 in the up and down directions is not less than 10 mm, so that the upper surface of the air-avoiding groove 21 always maintains a distance of not less than 10 mm from the hanging part 32 when the pressing plate 2 falls normally during operation, thereby ensuring the air-avoiding effect of the air-avoiding groove 21 and avoiding affecting the normal falling of the pressing plate 2; the distance L1 between the upper surface of the air-avoiding groove 21 and the upper surface of the hanging part 32 minus the movement stroke S of the pressing plate 2 in the up and down directions is not greater than 20 mm, which can avoid the size of the air-avoiding groove 21 being too large and avoiding affecting the structural strength of the pressing plate 2.

[0066] Further, refer to Figure 6 Along the second direction, the minimum distance L2 between the bottom wall of the air-avoiding groove 21 and the hanging portion 32 satisfies the following: 5mm≤L2≤10mm. It is understood that the minimum distance L2 between the bottom wall of the air-avoiding groove 21 and the hanging portion 32 can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm. The minimum distance L2 between the bottom wall of the air-avoiding groove 21 and the hanging part 32 is not less than 5 mm, so that the bottom wall of the air-avoiding groove 21 always maintains a distance of not less than 5 mm from the hanging part 32 when the pressing plate 2 falls normally during operation, ensuring the air-avoiding effect of the air-avoiding groove 21 and avoiding affecting the normal falling of the pressing plate 2; the minimum distance L2 between the bottom wall of the air-avoiding groove 21 and the hanging part 32 is not greater than 10 mm, so that when the pressing plate 2 falls out of control, the contact distance between the hanging part 32 and the surrounding wall of the air-avoiding groove 21 is larger, which can ensure the hanging effect of the hanging part 32.

[0067] The embodiment of the present application provides a mold. It should be noted that the mold in the present application may refer to a compression mold, a stamping mold, a die-casting mold, etc. For example, according to the molding material, the mold in the present application can be a hardware mold: such as a stamping mold, or a plastic mold, such as a compression mold, or a special mold: such as a die-casting mold, etc. For the mold, it is generally composed of an upper mold 100 and a lower mold, and the two parts can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. In addition, the mold also requires auxiliary components such as a mold base, a mold frame, a mold core, and a workpiece ejection device. These components are generally made into a universal type.

[0068] It should be noted that in the embodiments of this application, the mold material is not further limited. Exemplary mold materials include steel (such as cold work die steel, hot work die steel, plastic mold steel, etc.), aluminum alloy, and cast iron. These materials have advantages such as high hardness, good heat resistance, and high strength, and can meet the processing requirements of different molds.

[0069] The embodiment of the present application further provides a mold, comprising the above-mentioned upper mold 100 .
