DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0024] according to Figure 1-11 As shown, a punching die for a refrigerator liner 20 that can be quickly changed includes a frame 1, characterized in that a movable workbench 2 is provided on the frame 1, a simulated frame 3 is provided above the movable workbench 2, the liner 20 is placed on the simulated frame 3, and a plurality of side punching assemblies are also provided on the frame 1, the side punching assemblies include two groups of punching simulated parts, a front guide plate 4, a rear guide plate 5 and a movable plate 6, the rear guide plate 5 is provided with a guide column 7, the front guide plate 4 is slidably connected to the guide column 7, the two groups of the punching simulated parts are located on the front guide plate 4 and the rear guide plate 5, the movable plate 6 is provided with a retreat groove 8, and the movable plate 6 is moved to different positions so that the retreat groove 8 corresponds to the two groups of punching simulated parts respectively.

[0025] In the above-mentioned specific technical scheme, several groups of side punching assemblies are set, and the installation positions of the side punching assemblies are respectively located at the corresponding punching positions of the inner liner 20. Each group of side punching assemblies includes two groups of punching simulation parts, which punch the refrigerated inner liner 20 and the frozen inner liner 20 respectively. The punching simulation parts are placed on the front guide plate 4 and the rear guide plate 5. In the process of the side punching assembly moving toward the inner liner 20, the front guide plate 4 first contacts the inner liner 20, and then the front guide plate 4 slides along the guide column 7. The working punching simulation parts continue to move forward to punch the inner liner 20. The non-working punching simulation parts, that is, the end of the punching simulation parts corresponding to the retreat groove 8, enters the retreat groove 8, so that only one group of punching simulation parts performs the punching work. When the model of the inner liner 20 needs to be changed, the position of the movable plate 6 is adjusted so that the retreat groove 8 corresponds to the other group of punching simulation parts, thereby realizing punching of refrigerator liners 20 of different models, and the mode change is convenient.

[0026] The two groups of punching shaped parts respectively include a plurality of punching blocks and punching columns 10, which are used for punching the freezing liner and the refrigeration liner respectively.

[0027] The movable plate 6 is slidably mounted on a movable seat 11. A pull rod 12 is provided on one side of the movable plate 6.
