[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figures 1 to 4 As shown, in this embodiment, a punching type inclined wedge mold includes a driving block 1, a lower template 2, a punching die 3, a pressure plate 4, a punching punch 5 and a slider 6. The lower end of the driving block 1 is provided with a first inclined surface, the upper end of the slider 6 is provided with a second inclined surface, a pad 7 is connected between the first inclined surface and the second inclined surface, a nitrogen reset spring 8 is connected between the lower end of the slider 6 and the pressure plate 4, the upper end of the punching punch 5 is connected to the slider 6, and the lower end of the punching punch 5 passes through the pressure plate 4 and is inserted into the punching die 3, and the punching die 3 is located on the lower template 2.

[0021] During the downward movement of the driving block 1, the sliding block 6 moves downward at an angle through the sliding of the first inclined surface and the second inclined surface, and the punching punch 5 at the lower end of the slider 6 passes through the pressure plate 4 and then through the product 16 to perform a punching action. The punching punch 5 is inserted into the punching die 3, and the nitrogen return spring 8 is squeezed at this time. When the punching is completed, the driving block 1 rises and resets, pulling the slider 6 back. During the process of the punching punch 5 being driven to move upward, the nitrogen return spring 8 keeps pressing the pressure plate 4, so that the product 16 does not move. After the punching punch 5 leaves the pressure plate 4, the nitrogen return spring 8 is separated from the pressure plate 4, effectively protecting the product 16 from deformation. At this time, the product 16 can be taken away.

[0022] The die of the punching type wedge also includes an upper die base 9, an active cavity 10 is provided in the upper die base 9, a slider guide block 11 is installed in the active cavity 10, the slider guide block 11 clamps the slider 6, and the slider 6 slides in the slider guide block 11 along the inclined direction, an upper support plate 12 is connected to the upper side of the upper die base 9, a stroke limit pressure plate 13 is fixed on the slider guide block 11, a stroke limit notch is provided on one side of the slider 6, one end of the stroke limit pressure plate 13 is inserted into the stroke limit notch, the stroke limit pressure plate 13 limits the active position of the stroke limit notch, thereby limiting the movement of the slider 6, a punch clamping plate 14 is fixed to the lower end of the slider 6, the upper end of the punching punch 5 and the upper end of the nitrogen return spring 8 are both connected to the punch clamping plate 14, a lower die base 15 is connected to the lower side of the lower template 2, and the lower template 2 and the lower die base 15 are fixedly connected.

[0023] An active cavity 10 is arranged in the upper die seat 9, and a slider guide block 11 is placed in the active cavity 10 for guiding the slider 6. When the driving block 1 hits the slider 6, the slider 6 can move along the direction of the slider guide block 11, and the pressing plate 4 performs profiling positioning on the product 16. The punching die 3 cooperates with the punching punch 5 to complete the industrial control work. The formed inclined wedge has a small size, simple manufacturing principle, high precision, strong reliability, high consistency of fitter debugging, and small space occupation. While punching in a process, the product 16 can be formed, shaped, and other works can be performed. Batch standardized production corresponds to multiple sets of molds for a project, and the cost can be further reduced.

[0024] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
