[0026] The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be construed as limiting the present invention.
[0027] The terms first, second, etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features; in addition, it should be noted that unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, connection can be direct connection or indirect connection through an intermediate medium, and can be fixed connection, movable connection, detachable connection or integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will combine the accompanying drawings in the embodiments of the present invention Figure 1 -8 to clearly and completely describe the technical solutions in the embodiments of the present invention.
[0029] An embodiment of the present invention provides a trimming die for the inner liner of a refrigerator. Refer to Figure 1 - Figure 3, including a mounting base 10 and a template 20 detachably connected to the mounting base 10. The mounting base 10 is fixed to a refrigerator inner liner trimming machine. The template 20 includes a substrate 21 and a die core 22 provided on the substrate 21 and matching the shape of the mouth of the refrigerator inner liner. When trimming the refrigerator inner liner, the refrigerator inner liner is placed on the substrate 21, and the die core 22 plays a limiting role on the refrigerator inner liner, and then the trimming operation is carried out. When replacing refrigerator inner liner products of different models, only the template 20 needs to be disassembled, and there is no need to disassemble the mounting base 10, making the replacement of the trimming die more convenient. Moreover, the fixed mounting base 10 is a common base for all templates 20, avoiding model mismatches and realizing the rapid conversion of the template 20.
[0030] Refer to Figure 4 and Figure 5 , the mounting base 10 includes a support plate 11, a connecting rib plate 12 fixedly connected to the support plate 11, and a first connecting plate 13 fixedly connected to the support plate 11. An avoidance hole for installing the first connecting plate 13 is provided in the connecting rib plate 12. The first connecting plate 13 is inserted through the avoidance hole and fixed to the support plate 11 by a fixing member. A first fixing hole 131 is provided on the first connecting plate 13, and a mounting hole 211 is provided on the substrate 21. The positions, sizes, and shapes of the first fixing hole 131 and the mounting hole 211 match. A fastener is detachably connected between the template 20 and the first connecting plate 13. When it is necessary to fix the template 20, the fastener is used to pass through the mounting hole 211 and the first fixing hole 131, and the template 20 can be fixed by using one fastener. Therefore, the disassembly and installation process is relatively simple, and the replacement of the template 20 is more convenient.
[0031] The mounting hole 211 is located at the center position of the template 20, and the first fixing hole 131 is located at the center position of the first connecting plate 13, and the axis of the first fixing hole 131 coincides with the center point of the mounting base 10. The mounting hole 211 and the first fixing hole 131 located at the center position make the fixing force between the mounting base 10 and the template 20 concentrate on the center position of the mounting base 10 and the template 20, so that the supported template 20 will not have the problem of uneven supporting force on both sides, and the supporting force of the template 20 is relatively stable.
[0032] In other embodiments, the substrate 21 and the first connecting plate 13 can be detachably connected by other means, such as a mortise and tenon structure, a snap-fit structure, etc., which will not be elaborated here.
[0033] Refer to Figure 4 , Figure 6 and Figure 7, a number of positioning structures are provided between the mounting base 10 and the template 20. The positioning structures include positioning holes 31 provided on the substrate 21, positioning sleeves 32 that cooperate with the positioning holes 31, and positioning posts 33 fixed to the side of the mounting base 10 facing the template 20. The positions, sizes, and shapes of the positioning posts 33 and the positioning sleeves 32 match. When replacing the template 20, the number of positioning structures accurately positions the template 20 and the mounting base 10, eliminating the need to repeatedly calibrate the positions of the template 20 and the mounting base 10, thus avoiding angular deviation of the template 20 and enabling rapid fixation between the template 20 and the mounting base 10.
[0034] Refer to Figure 6 , a guiding inclined surface 321 is provided at one end edge of the positioning sleeve 32 facing the positioning post 33. The provision of the guiding inclined surface 321 serves a guiding function and facilitates the connection between the positioning post 33 and the positioning sleeve 32. A guiding inclined surface 321 can also be provided at one end edge of the positioning post 33 facing the positioning sleeve 32.
[0035] In this embodiment, four groups of positioning structures are provided corresponding to the corner positions of the mounting base 10.
[0036] In other embodiments, the positioning holes 31 and the positioning sleeves 32 in the positioning structures can be provided on the mounting base 10, and the positioning posts 33 can be fixed to the side of the template 20 facing the mounting base 10. Other positioning methods with different structures can also be adopted, and specific limitations are not made here.
[0037] Refer to Figure 7 , a number of weight-reducing holes 212 are provided on the substrate 21. The number of weight-reducing holes 212 is distributed along the length and width directions of the substrate 21. The weight-reducing holes 212 can reduce the overall weight of the template 20, making it easier for workers to transport the template 20 and reducing the risk of personnel being injured by dropping.
[0038] Refer to Figure 5 , the mounting base 10 further includes a second connecting plate 14 fixed to the connecting rib plate 12. A second fixing hole 141 is provided on the second connecting plate 14. The mounting base 10 is fixed to the refrigerator inner liner trimming machine through a fixing member, and the fixing member passes through the second fixing hole 141. The fixing method of the mounting base 10 to the refrigerator inner liner trimming machine is relatively simple. When it is necessary to replace the mounting base 10, it can be quickly disassembled and installed. The axes of the second fixing hole 141, the first fixing hole 131, and the mounting hole 211 are collinear, so that the connection position of the mounting base 10 to the trimming machine and the connection position of the mounting base 10 to the template 20 are approximately located in the same axial region. Even if the mounting base 10 is connected to the trimming machine and the mounting base 10 is connected to the template 20 through a single fastener or fixing member, the stability of the connection can be ensured.
[0039] In this embodiment, refer to Figure 7 and Figure 8, there are two die core groups provided on the substrate 21. The two die core groups are symmetrically arranged with respect to the center line of the substrate 21 extending in the width direction. The two die core groups enable each template 20 to limit the positions of two refrigerator liners 100, and at the same time perform trimming operations on the two refrigerator liners 100. The die core group includes three die cores 22. The three die cores 22 match three of the side edges of the refrigerator liner 100. One of the die cores 22 is fixed on the side edge of the substrate 21 in the width direction, and the other two die cores 22 are fixed on the opposite two side edges of the substrate 21 in the length direction. There is no die core 22 provided at the middle position of the substrate 21. The three die cores 22 can play a role in limiting and fixing the refrigerator liner 100, and can reduce the weight of the template 20, making the transportation of the template 20 easier.
[0040] A gap for the trimming device to perform trimming operations is left between two adjacent die core groups. When the refrigerator liner 100 is connected to the template 20, it is convenient for the trimming device to remove the waste on the side where the two refrigerator liners 100 are close to each other. Of course, in an alternative embodiment, multiple die core groups can be provided on the template. The specific number of die core groups can be adjusted accordingly according to the structure of the trimming machine. Herein, no specific limitation is made.
[0041] The planar area of the support plate 11 is smaller than the planar area of the substrate 21. When the template 20 needs to be replaced, the outer edge of the substrate 21 with a larger area protrudes from the outer edge of the support plate 11, which is convenient for separating the substrate 21 from the support plate 11. Moreover, the thicknesses of both the support plate 11 and the substrate 21 are set to be relatively thin, reducing the volume and weight of the mounting seat 10 and the template 20, which is convenient for the staff to carry and install.
[0042] The above-mentioned fasteners and fixing parts are all screws or bolts, which are convenient for fixing and disassembling the template 20 and the mounting seat 10.
[0043] An embodiment of the present utility model provides a trimming machine for refrigerator liners, which at least includes a transporting device and a trimming device (not shown in the figure). The above-mentioned trimming die is connected to the transporting device, and the mounting seat 10 is fixedly connected to the operating device. When trimming operations need to be performed on the liner, the template 20 corresponding to the refrigerator liner model is installed on the mounting seat 10, the refrigerator liner is assembled to the template 20, and the transporting device is used to move the refrigerator liner to the trimming area, and the trimming device performs trimming operations on the refrigerator liner. When the model of the refrigerator liner is changed, only the template 20 corresponding to the model needs to be replaced, and the operation is convenient and fast.
[0044] The structure, features and effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present utility model, but the present utility model is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present utility model, or equivalent embodiments modified into equivalent changes, shall still be within the protection scope of the present utility model as long as they do not exceed the spirit covered by the specification and the drawings.
