Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of vehicle parts, and in particular to a window-on / off switching device and a vehicle side panel mold. Background Art

[0002] As people's demand for vehicles increases, freight vans and passenger buses are often developed at the same time during the vehicle development process, resulting in windowless and windowed states in the rear section of the side outer panel. In order to save the development cost of the stamping die, the blind window and windowed states are realized through the same set of dies.

[0003] In the related art, the punch is only fixedly connected to the upper die seat by four guide pillars. This solution requires manual positioning when switching between the window and non-window states during production. It is impossible to achieve rapid positioning between the punch and the upper die seat during the switching process. In addition, during the stamping process, there may be relative displacement between the punch and the upper die seat, affecting the stamping effect. Utility Model Content

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0031] In the process of automobile manufacturing, there are often situations similar to the simultaneous development of freight box trucks and passenger buses. At this time, in the production process of the rear section of the side outer panel of the automobile, there is a demand for two states: with windows and without windows. To meet the production needs of both with and without windows, production molds with windows and without windows are required. However, in order to save the development cost of the stamping mold, the mold is required to be adaptable in the production process, so that both with and without windows can be achieved through the same set of molds.

[0032] An embodiment of the present application provides a car side panel mold, which includes a lower mold base and a window-or-no window switching device. The lower mold base is arranged in a counterposition with an upper mold base with the window-or-no window switching device, and the upper mold base and the lower mold base are molded together to manufacture the car side panel.

[0033] The automobile side panel mold provided in the embodiment of the present application is provided with a window-or-no window switching device. Therefore, when it is necessary to produce an automobile side panel with windows, the window-or-no window switching device is switched to the window-or-no window state, and the automobile side panel with windows can be produced by closing the upper mold base with the lower mold base. Correspondingly, when it is necessary to produce an automobile side panel without windows, the window-or-no window switching device is switched to the window-or-no window state, and the automobile side panel without windows can be produced by closing the upper mold base with the lower mold base.

[0034] It should be explained that the molds mentioned in the embodiments of the present application may be stamping molds, die-casting molds, injection molds, etc., and the present application does not limit the molding method. The mold generally includes an upper mold base, a lower mold base and a mold cavity, and is generally a mold of the upper mold base and the lower mold base. The material is made into the required parts in the mold cavity by methods including but not limited to stamping, injecting molten plastic materials, etc. For example, the molds mentioned in the embodiments of the present application can be used to achieve the state switching of sheet metal parts, especially for some situations where pneumatic switching cannot be achieved or there is no compressed air in the production conditions.

[0035] It should be added that the automobile including the vehicles mentioned in the embodiments of the present application may refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to the vehicle model, the vehicles in the embodiments of the present application may refer to sedan models, off-road models, multi-purpose vehicles (MPV) or other models.

[0036] The present application embodiment provides a window switching device, referring to Figure 1 , Figure 2 The window switching device comprises an upper die base 1 and a cutting assembly 2, wherein the upper die base 1 has an installation area 11, and the installation area 11 is provided with a connecting structure 12 and a first positioning member 13; Figure 5The cutting assembly 2 is detachably connected to the mounting area 11 of the upper die holder 1 through the connecting structure 12 along the mold closing direction. The cutting assembly 2 includes a second positioning member 21. When the cutting assembly 2 is connected to the upper die holder 1, refer to Figure 3 The first positioning member 13 and the second positioning member 21 are aligned and matched to limit the relative displacement of the upper mold base 1 and the cutting assembly 2 along the first direction, wherein the first direction is perpendicular to the mold closing direction.

[0037] The embodiment of the present application provides a window-or-no switching device, wherein the upper mold base 1 has an installation area 11, and a connecting structure 12 is provided in the installation area 11 for connecting the cutting assembly 2. The cutting assembly 2 is detachably connected to the installation area 11 of the upper mold base 1 along the mold closing direction through the connecting structure 12. Since a first positioning member 13 is also provided in the installation area 11 of the upper mold base 1, and the cutting assembly 2 includes a second positioning member 21, when the upper mold base 1 is connected to the cutting assembly 2, the first positioning member 13 and the second positioning member 21 cooperate to limit the upper mold base 1 and the cutting assembly 2. Therefore, the first positioning member 13 and the second positioning member 21 limit the relative displacement of the upper mold base 1 and the cutting assembly 2 along the first direction, further improving the precise positioning and stability between the upper mold base 1 and the cutting assembly 2. The first direction is perpendicular to the mold closing direction.

[0038] Here, it should be noted that the mold closing direction refers to the direction of mold assembly and disassembly. Figure 5 The first positioning member 13 and the second positioning member 21 limit the relative displacement between the upper mold base 1 and the cutting component 2 along the first direction, and the first direction is perpendicular to the mold closing direction, which means that the first positioning member 13 and the second positioning member 21 limit the displacement between the upper mold base 1 and the cutting component 2 in the direction perpendicular to the mold assembly and disassembly. In this way, through the cooperation of the first positioning member 13 and the second positioning member 21, the limited cooperation of the upper mold base 1 and the cutting component 2 in the connected state can be achieved, avoiding the relative displacement between the upper mold base 1 and the cutting component 2 in the direction perpendicular to the mold closing direction during the connection process. Similarly, the first positioning member 13 and the second positioning member 21 can perform precise positioning for the upper mold base 1 and the cutting component 2 in the connected state, thereby improving the accuracy and stability of the connection between the upper mold base 1 and the cutting component 2.

[0039] Among them, refer to Figure 2 , Figure 3 and Figure 4The first positioning member 13 is a protrusion arranged on the upper mold base 1, and the second positioning member 21 is a groove arranged on the cutting component 2. The setting directions of the protrusion and the groove are both the extension direction of the first direction, and the positions correspond to each other. When the upper mold base 1 and the cutting component 2 are in a connected state, the first positioning member 13 and the second positioning member 21 cooperate. At this time, the protrusion arranged on the upper mold base 1 and the groove arranged on the cutting component 2 correspond to each other to realize the positioning and limiting of the upper mold base 1 and the cutting component 2.

[0040] In this way, the setting directions of the protrusions and grooves are both extension directions of the first direction, and the positions set on the upper mold base 1 and the cutting component 2 correspond to each other, which can ensure that the protrusions and grooves precisely cooperate with each other during matching, thereby achieving accurate positioning and mutual nesting of the protrusions and grooves. The mutual nesting of the protrusions and grooves can resist relative displacement, which can effectively limit the displacement of the upper mold base 1 and the cutting component 2 along the first direction, increase the stability of the connection, and have a positioning effect during connection, so as to perform precise positioning of the upper mold base 1 and the cutting component 2 during connection.

[0041] It should be added that the shape of the protrusions and grooves can be rectangular, circular, trapezoidal or other geometric shapes. The selection of the specific shape depends on the shape and size of the mold. The shape with accurate positioning and stable connection is preferred according to different requirements. The size of the protrusions and grooves should adapt to the overall mold structure and may depend on the size and design of the manufactured automobile side panel. The size of the protrusions and grooves can be flexibly set according to different manufacturing requirements.

[0042] Further, refer to Figure 3 A first key groove 131 is provided on the upper die base 1, and the first positioning member 13, which is a protrusion provided on the upper die base 1, is a key pin 132, and the key pin 132 is provided in the first key groove 131. The second positioning member 21 is a second key groove 211 provided on the cutting assembly 2. When the upper die base 1 and the cutting assembly 2 are in a connected state, the first key groove 131 and the second key groove 211 are aligned and matched, and the key pin 132 is located in the space enclosed by the first key groove 131 and the second key groove 211.

[0043] Since the window-without switching device needs to switch the window-without state multiple times according to the production requirements of the window-without state during use, the first positioning member 13 and the second positioning member 21 are required to position the upper mold base 1 and the cutting assembly 2 each time during the switching process, which requires the positioning members to be able to withstand a high frequency of use and be easy to maintain. In this case, the key pin 132 is used as the first positioning member 13, and the key pin 132 and the key slot can withstand high-frequency operations and are not easily damaged. Even if they need to be repaired and replaced later, the key pin 132 and the key slot are also less costly in terms of maintenance and replacement.

[0044] It should be added that the shapes of the first keyway 131 and the second keyway 211 depend on the shapes of the key pin 132, and the sizes should match the corresponding key pin 132 to ensure stable connection and positioning. The material selection of the key pin 132 needs to consider wear resistance, strength and corrosion resistance, and can be metal or alloy materials, etc.

[0045] In order to achieve more stable positioning and limiting between the upper mold base 1 and the cutting assembly 2, the first positioning member 13 and the second positioning member 21 are each set to be multiple, and the multiple second positioning members 21 are arranged at intervals along the outer circumferential direction of the cutting assembly 2. The multiple first positioning members 13 and the multiple second positioning members 21 correspond to each other one by one and are arranged in the installation area 11 of the upper mold base 1.

[0046] In this way, multiple first positioning members 13 and second positioning members 21 are arranged in a one-to-one correspondence, and the positioning accuracy and connection stability of the upper mold base 1 and the cutting assembly 2 can be increased through multi-point positioning. At the same time, the positions of multiple second positioning members 21 are arranged to be spaced apart along the outer circumferential direction of the cutting assembly 2. This position and arrangement method of the setting can make the connection part have better symmetry and help to evenly distribute the force at the connection part.

[0047] It should be noted that the number of positioning members is not limited and can be determined according to production requirements and the size of the upper mold base 1 and the cutting assembly 2. The positioning members not only resist the displacement between the upper mold base 1 and the cutting assembly 2 along the first direction when the upper mold base 1 and the cutting assembly 2 are connected, but also provide precise positioning between the upper mold base 1 and the cutting assembly 2 during the connection process, so that the connection position between the upper mold base 1 and the cutting assembly 2 is more accurate, thereby improving the accuracy and stability of the mold in production.

[0048] The installation area 11 on the upper die base 1 can be set according to actual needs. For example, the installation area 11 can be set to a flat plate structure, a groove structure or a through structure to provide an installation area 11 for the cutting assembly 2. Since the cutting assembly 2 has a certain weight and the cutting assembly 2 and the upper die base 1 need to be frequently installed and disassembled when switching between the state with or without a window, the method of installing and removing the cutting assembly 2 on the upper die base 1 should be more convenient. In comparison, the flat plate structure and the groove structure are not through, and the installation and removal of the cutting assembly 2 can only be performed on one side of the upper die base 1. Therefore, it is more convenient to install and disassemble the cutting assembly 2 when switching between the state with or without a window.

[0049] In some embodiments provided in this application, reference is made to Figure 2 An installation window 14 is provided on the upper mold base 1 along the mold closing direction, and the cutting assembly 2 is detachably connected to the installation area 11 of the upper mold base 1 through a connecting structure 12, wherein the installation area 11 is the inner edge of the installation window 14 and the space enclosed by it.

[0050] In some embodiments provided in the present application, the installation area 11 is configured as a through window along the mold closing direction, so that the cutting component 2 can be installed and removed through the through window without flipping the upper mold base and using compressed air, thereby completing the switching between the windowed and non-windowed states, thereby shortening the time consumption for state switching and reducing the difficulty of human operation.

[0051] It should be noted that the shape and size of the installation window 14 are not limited. Figure 2 , can be square, round, etc., and the corresponding shape is adapted according to the shape of the cutting component 2, and the size of the installation window 14 should be set according to the window size required for the installation of the cutting component 2. The size and shape of the cutting component 2 are determined according to the production requirements required in the production process.

[0052] In some embodiments provided in this application, refer to Figure 2 and Figure 5 The windowless switching device also includes a presser 3, which is arranged on one side of the installation window 14 close to the lower mold base along the mold closing direction. During the installation of the cutting component 2, the cutting component 2 first contacts the installation window 14 and then contacts the presser 3. In order to avoid interference between the cutting component 2 and the presser 3 during the installation of the cutting component 2 and when it is connected to the upper mold base 1, resulting in equipment damage and other problems, a guide isolation structure 22 is provided between the cutting component 2 and the presser 3. Figure 4 and Figure 5 , and when the cutting assembly 2 and the upper die base 1 are in a connected state, at least one of the cutting assembly 2 and the presser 3 is slidably connected to the guide isolation structure 22.

[0053] Therefore, when the cutting component 2 is being installed and disassembled, the guide isolation structure 22 can be used to guide and isolate the cutting component 2 and the presser 3 to avoid collision between the cutting component 2 and the presser 3; when the cutting component 2 is installed on the upper mold base 1, the guide isolation structure 22 can be used to alleviate the mutual interference between the cutting component 2 and the presser 3 during operation, thereby reducing the risk of damage to the equipment. This is due to the fact that when in the connected state, at least one part between the cutting component 2 and the presser 3 is slidably connected to the guide isolation structure 22. Because the interactive connection can absorb potential vibrations and impact forces and reduce mechanical stress, this technical solution can significantly improve the service life of the equipment.

[0054] It should be noted that the mold closing direction refers to the direction of mold assembly. Figure 2 and Figure 5The mold generally includes an upper mold base, a lower mold base and a mold cavity. The position of the press 3 is located in the installation window 14 on the upper mold base 1, close to the side of the lower mold base along the assembly and disassembly direction of the mold. The guide isolation structure 22 can be a spring element introduced to maintain the state of sliding connection and isolation through elastic force, or a ball rail guide is used to ensure that the ball track matches the corresponding guide track, thereby providing a smooth and low-friction sliding guide and isolation effect. In addition, the guide isolation structure 22 can also be other technical solutions that can achieve the guiding and isolation effects.

[0055] Further, refer to Figure 4 and Figure 5 The guide isolation structure 22 is a sliding bearing sleeved on the cutting assembly 2. When the upper die base 1 and the cutting assembly 2 are in a connected state, relative movement can be achieved between the cutting assembly 2 and the press 3 through the sliding bearing.

[0056] The sliding bearing provides a mechanism that allows the upper die base 1 and the cutting assembly 2 to slide relative to each other, and the cutting assembly 2 and the press 3 to slide relative to each other when the upper die base 1 and the cutting assembly 2 are in the connected state. This means that during the cutting operation, the relative movement between the cutting assembly 2 and the press 3 can slide smoothly through the sliding bearing without causing additional resistance or interference, thereby preventing collision and jamming caused by the asynchronous movement of the press 3 and the cutting assembly 2 during the operation.

[0057] It should be added that the sliding bearing is sleeved on the cutting component 2, and the specific position and fixing means of the sleeve can be determined according to specific needs. The position of the sleeve can be selected from the area where collision is prone to occur between the cutting component 2 and the press 3. The fixing means of the sleeve can be threads, pins, clamping devices, etc., and the embodiments of the present application are not limited to this.

[0058] In some embodiments provided in this application, refer to Figure 2 and Figure 4 The cutting assembly 2 is connected to the mounting area 11 of the upper mold base 1 through a connecting structure 12. The connecting structure 12 is a mounting hole 121 set on the upper mold base 1 and the cutting assembly 2. The mounting hole 121 includes a first mounting hole in the mounting area 11 on the inner edge of the mounting window 14 of the upper mold base 1, and a second mounting hole set on the cutting assembly 2 corresponding to the position of the first mounting hole. When the upper mold base 1 and the cutting assembly 2 need to be connected, fasteners are used to cooperate with the first mounting holes and the second mounting holes corresponding to each other on the upper mold base 1 and the cutting assembly 2. The connection and separation of the upper mold base 1 and the cutting assembly 2 are achieved by installing and removing the fasteners.

[0059] Since the connection structure 12 is configured as a structure corresponding to the mounting hole and the fastener, the structure has strong adaptability, and the corresponding mounting hole can be adaptively designed according to the different sizes and requirements of the upper die base 1 and the cutting assembly 2, and then the appropriate fastener is matched, thereby improving the adaptability and versatility of the device. Moreover, since the fastener is used as the connection method, the cost is low and it is easy to maintain and replace, thereby improving the maintainability of the device.

[0060] It should be noted that the fasteners required for connecting the upper die base 1 and the cutting assembly 2 can be locking bolts, latches, clamps, etc., which have the same effect, and the embodiments of the present application do not limit this. The mounting holes are designed to be evenly distributed in the mounting area 11 and at positions corresponding to the cutting assembly 2, and the number and size are determined by the size of the upper die base 1 and the cutting assembly 2.

[0061] In some embodiments provided in this application, refer to Figure 4 and Figure 5 The cutting assembly 2 includes a tool seat 23 and a tool 24. The tool 24 is fixed on the mold side of the tool seat 23. A lifting member 231 is arranged on the tool seat 23. The lifting member 231 is used for the cutting assembly 2 to be towed by the towing device, that is, the towing device can tow the cutting assembly 2 through the lifting member 231.

[0062] Since the cutting assembly 2 includes a lifting piece 231, the traction device can tow the cutting assembly 2 through the lifting piece 231. Then, when it is necessary to switch to the windowed state, the traction device can lift the cutting assembly 2 as a whole into the installation window 14 of the upper mold base 1 through the traction piece to achieve the windowed state; when it is necessary to switch to the windowless state, the traction device can lift the cutting assembly 2 as a whole out of the installation window 14 of the upper mold base 1 through the traction piece to achieve the windowless state. This greatly reduces the operation time and difficulty of the technician when switching between the windowed state and the windowless state.

[0063] It needs to be explained that the mold closing side refers to one side of the mold closing direction, that is, the tool 24 is installed on one side of the mold closing direction of the tool seat 23, that is, the blade of the tool 24 is facing the side of the lower mold seat, the tool is used to cut the sheet metal parts, and the tool 24 is connected to the tool seat 23 by bolts.

[0064] It should be added that the lifting member 231 includes a lifting hole 2311 and a lifting ring, which is used for the cutting assembly 2 to be towed by the towing device. The lifting hole 2311 is arranged on the inner side of the area where the connecting structure 12 is located on the blade mounting seat. Figure 4The lifting holes 2311 are usually set to 4, and can be increased or decreased accordingly according to the requirements of different cutting components 2. The lifting ring is screwed into the corresponding lifting hole 2311, and the traction equipment can be used to lift out or lift in the cutting component 2. The traction equipment can be a crane, an electric hoist, a winch, or other equipment that can achieve a traction effect.

[0065] To clearly describe the present solution, by way of example, based on the embodiments provided in the present application, the following operations may be performed to implement switching between the windowed and windowless states of the windowless device.

[0066] Specifically, first use a traction device to lift the cutting assembly 2 as a whole into the installation space of the upper mold base 1 through the lifting member 231. During installation, the first positioning member 13 and the second positioning member 21 position the upper mold base 1 and the cutting assembly 2. Then, the upper mold base 1 and the cutting assembly 2 are fixedly connected through the connecting structure 12, thereby realizing the switching of the device to the window state; correspondingly, the connecting structure 12 connecting the upper mold base 1 and the cutting assembly 2 is removed, and the traction device is used to lift the cutting assembly 2 out of the installation space of the upper mold base 1 as a whole through the lifting member 231, thereby realizing the switching of the device to the windowless state.

[0067] This switching process only requires the overall lifting in and out of the components, realizing the common mold development of multi-state parts, saving development costs, shortening the time of device state switching, reducing the difficulty and intensity of personnel operation, and does not require the use of compressed air. It is suitable for some stamping plants with poor production conditions.

[0068] The above is only an implementation method of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
