Description

Technical Field

[0001] This utility model relates to the technical field of mechanical tooling, specifically to a stop die device. Background Technology

[0002] As is well known, in order to reduce the development cost of bus products, shorten the development cycle, and improve development efficiency, it is necessary to make inspection fixtures according to the glass model of the bus provided by the customer when developing bus products, so that the customer can further refine the sheet metal shape of the front of the bus according to the glass model of the bus.

[0003] Research has found that, in current technologies, the fixtures developed based on digital models of bus glass are typically handcrafted by workers, often resulting in deviations that fail to meet high-precision requirements. Furthermore, subsequent evaluation of the product's molding process necessitates adjustments to the fixture's surface. Therefore, in actual bus product development, manufacturing only the fixture can easily lead to inconsistencies in development progress between the glass and frame manufacturers due to repeated adjustments, resulting in a mismatch between the final glass product and the frame, ultimately causing defects in subsequent vehicle assembly. Utility Model Content

[0004] The technical problem to be solved by this utility model is: This utility model discloses a stop die device to solve the problem that when developing bus products, only manufacturing inspection fixtures and tooling can easily cause the final glass product to be mismatched with the vehicle frame, resulting in poor subsequent vehicle assembly.

[0006] In the above-mentioned technical solution of this utility model, the existing technology of developing bus products by only manufacturing inspection fixtures and tooling can easily lead to mismatch between the final product and the customer's vehicle frame, resulting in poor subsequent vehicle assembly. This utility model discloses a new stop-mold device. This stop-mold device has an optimized structure design. During the development of the above-mentioned bus products, after the inspection fixtures and tooling are manufactured, the R&D personnel can make a stop-mold device (i.e., a dummy glass) and send it to the customer. Using this stop-mold device as a basis for simultaneous development can avoid the problem of poor glass product installation caused by inconsistent development basis.

[0007] In practical applications, the outer dimension contour of the stop die in the stop die device of this utility model is the outer dimension contour of the outer edge of the vehicle frame, so that the stop die can achieve a tight fit with the vehicle frame; at the same time, the upper top surface of the stop die is the inner surface of the glass on the vehicle frame, and the thickness of the stop die is approximately the thickness of the glass; thus, the stop die can effectively assist customers in correcting the vehicle frame, ensuring consistency of development basis and reducing the phenomenon of poor vehicle assembly.

[0008] Therefore, the stop die device of this utility model can conveniently and effectively convey the development progress of the current inspection tooling to the customer, so as to use the stop die device as the basis for synchronous development, facilitate synchronous development progress, improve development efficiency, and avoid the problem of poor quality of glass products in the future. It has good promotion prospects and application value.

[0009] Furthermore, in the stop die device of this utility model, the stop die component has a hollow inner cavity, and the stop die component includes a first side, a second side, a third side and a fourth side connected end to end, and the first side, the second side, the third side and the fourth side together form the hollow inner cavity.

[0010] Furthermore, in the stop die device described in this utility model, the first side, the second side, the third side, and the fourth side are all arc-shaped sides, and the arc curvature of the first side, the second side, the third side, and the fourth side are respectively the curvature of the four peripheries of the glass.

[0011] Furthermore, in the stop die device described in this utility model, the ends of the first side, the second side, the third side and the fourth side all extend towards their middle parts in a direction close to the mounting base.

[0012] Furthermore, in the stop die device of this utility model, the first side and the third side are arranged opposite to each other, and the second side and the fourth side are arranged opposite to each other; wherein, the extension length of the first side and the third side is greater than the extension length of the second side and the fourth side.

[0013] Furthermore, in the stop die device described in this utility model, the length difference between the two diagonals of the stop die is controlled to be ≤1mm.

[0015] Furthermore, in the stop die device of this utility model, the support frame includes multiple support and positioning components. The support and positioning components include a first support column and a second support column arranged in pairs. One end of the first support column and the second support column are connected to the same positioning point on the bottom surface of the stop die, and the other end are connected to different positioning points on the mounting base, so that the extension directions of the first support column and the second support column are arranged at an angle.

[0016] Furthermore, in the stop die device described in this utility model, the distance between two adjacent support and positioning components is 20~30mm.

[0017] In the above-mentioned technical solution of this utility model, in order to effectively support the weight of the entire stop die part and ensure that the stop die part is subjected to uniform force, and to avoid deformation of the stop die part due to uneven force, in practical applications, multiple support and positioning components can be sequentially arranged along the extension direction of the first side, the second side, the third side and the fourth side of the stop die part for support, that is, multiple pairs of first support columns and second support columns are arranged for support, and one is welded at a spacing of 20~30mm.

[0031] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] Considering that the fixtures for the glass in the vehicle frame are usually made by hand during the current vehicle development process, and the surface of the fixture needs to be adjusted and refined afterward, if only the fixture is manufactured, the multiple adjustments to the fixture can easily lead to inconsistencies in the development progress between the two parties, resulting in a mismatch between the final glass product and the vehicle frame prepared by the customer.

[0033] Please refer to Figure 1 as well as Figure 5 As shown, this utility model designs a stop die device, which is equipped with a stop die component. That is, after the existing developers have prepared and obtained the inspection fixture, they can prepare the stop die component based on the inspection fixture, so that the stop die component can obtain the same size and shape as the inspection fixture, so that it can be sent to the customer. The stop die component 3 is used as the basis for synchronous development, avoiding the product installation failure caused by the inconsistency of the development basis between the two parties.

[0034] In this embodiment, in order to facilitate the loading of the above-mentioned stop die, the stop die device designed by this utility model further includes: a mounting base 1, a support frame 2, and a positioning column 4; wherein, the above-mentioned stop die 3 is disposed on the mounting base 1, and one end of the support frame 2 is connected to the mounting base 1, and the other end of the support frame 2 is used to connect to the bottom surface of the stop die 3 to support the above-mentioned stop die.

[0035] In this utility model, in order to ensure that the stop cavity mold 3 can serve as a basis for synchronous development, in actual setting, it is necessary to specifically control the upper top surface 35 of the stop cavity mold 3 to be the inner surface of the glass on the vehicle frame; and control the outer dimension contour of the stop cavity mold 3 to be the dimension contour of the outer edge of the vehicle frame.

[0036] It should be noted that in this embodiment, the aforementioned vehicle frame can specifically be a bus frame used to mount the windshield; of course, in some other embodiments, it can also be a frame of other vehicles.

[0037] Based on this design, in practical applications, the outer dimension contour of the stop cavity mold 3 of this utility model is the outer edge dimension contour of the vehicle frame, so that the stop cavity mold 3 can achieve a tight fit with the vehicle frame; at the same time, the upper top surface 35 of the stop cavity mold 3 is the inner surface of the glass provided on the vehicle frame, and the thickness of the stop cavity mold 3 is approximately the thickness of the glass; thus, according to the size and contour of the stop cavity mold 3, customers can be effectively assisted in correcting the vehicle frame, ensuring consistency in development basis and reducing the phenomenon of poor vehicle assembly.

[0038] Accordingly, see Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the stop cavity mold 3 is specifically provided with a hollow inner cavity, and the stop cavity mold 3 includes a first side 31, a second side 32, a third side 33 and a fourth side 34 connected end to end, so that the first side 31, the second side 32, the third side 33 and the fourth side 34 can surround and form the hollow inner cavity.

[0039] And, as Figure 4 and Figure 5 As shown, considering the need for application in the development of bus products, the windshield installed on the bus frame usually has a certain curvature. Therefore, in this embodiment, the first side 31, the second side 32, the third side 33, and the fourth side 34 of the corresponding developed stop mold 3 are all curved sides. Furthermore, the curvature of the first side 31, the second side 32, the third side 33, and the fourth side 34 are the curvatures of the four peripheries of the glass installed on the frame.

[0040] Meanwhile, in this embodiment, the upper top surface 35 of the stop cavity mold 3 is the inner surface of the glass on the vehicle frame. Therefore, the ends of the first side 31, the second side 32, the third side 33 and the fourth side 34 can be further arranged to extend towards the middle of themselves in a direction close to the mounting base 1.

[0041] It should be noted that, in this embodiment, when preparing the aforementioned stop die 3, the first side 31, second side 32, third side 33, and fourth side 34 can be prepared using an 8*20 flat iron according to the profile of the inspection fixture, in order to obtain the curvature of the four peripheries of the glass on the vehicle frame. Wherein, as... Figure 5 As shown, in this embodiment, the first side portion 31 and the third side portion 33 are arranged opposite to each other, and the second side portion 32 and the fourth side portion 34 are arranged opposite to each other, and the extension length of the first side portion 31 and the third side portion 33 is greater than the extension length of the second side portion 32 and the fourth side portion 34.

[0042] Therefore, according to Figure 3 As shown, in this embodiment, after the above-mentioned stop cavity mold 3 is prepared according to the fixture, it is also necessary to test the stop cavity mold 3 to determine whether the stop cavity mold 3 is consistent with the surface of the fixture. This test can be performed according to the verification method of the fixture.

[0043] And, as Figure 3 As shown, it is necessary to specifically detect and control the length difference of the two diagonals L1 and L2 of the stop die 3 to be ≤1mm; control the horizontal height difference of the two diagonals L1 and L2 of the stop die 3 to be ≤1mm; and at the same time, control the dimensions of the upper chord length L3 and the lower chord length L4 of the stop die 3 to ensure that the difference between the two is ≤1mm.

[0044] Accordingly, such as Figure 1 and Figure 2 As shown, in the stop die device of this utility model, in order to effectively support the stop die 3, the support frame 2 includes multiple support positioning components in actual application. The support positioning components include a pair of first support columns 21 and second support columns 22. One end of the first support column 21 and the second support column 22 are connected to the same positioning point on the bottom surface of the stop die 3, and the other end is connected to different positioning points on the mounting base 1, so that the extension directions of the first support column 21 and the second support column 22 are set at an angle.

[0045] Meanwhile, in order to effectively support the weight of the entire stop die 3 and ensure that the stop die 3 is subjected to uniform force, and to avoid deformation of the stop die 3 due to uneven force, in practical applications, multiple support and positioning components can be sequentially set along the extension direction of the first side 31, the second side 32, the third side 33 and the fourth side 34 of the stop die 3 for support. That is, multiple pairs of first support columns 21 and second support columns 22 are set for support, and one is welded at a spacing of 20~30mm.

[0046] In addition, such as Figure 2 As shown, in this embodiment, the support frame 2 is also provided with four third support columns 23. One end of the third support column 23 is connected to the bottom surface of the four corners of the stop die 3, and the other end is connected to the mounting base 1 to support the four corners of the stop die 3.

[0047] In addition, such as Figure 2 As shown, in this embodiment, in order to prevent the stop die 3 from deforming and thus affecting the normal use of the stop die device, four positioning posts 4 are also provided. These four positioning posts 4 are specifically located in the hollow inner cavity of the stop die 3 and are respectively set to the four corners of the stop die 3; wherein, the two ends of the positioning posts 4 are respectively connected to two adjacent sides of the stop die 3.

[0048] In summary, the stop die device designed using this utility model can conveniently and effectively convey the current development progress of the inspection tooling to the customer, so as to use the stop die device as a basis for synchronous development, which facilitates the synchronous development progress of both parties, improves development efficiency, and avoids the problem of poor quality of glass products in the future. It has good prospects for promotion and application value.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
