In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0022] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] An embodiment of the present utility model discloses a punching die for a semiconductor automotive-grade silicon carbide power module, as Figures 1 - 3 shown, including: a template 1, a backing plate 2, a fixed seat 3, and a cover plate 4 arranged in sequence from bottom to top. A product to be punched is placed between the fixed seat 3 and the cover plate 4. A movable latch 5 that is hinged to the fixed seat 3 and is clamped to the cover plate 4 is provided on the fixed seat 3. A first spring 6 is connected between the movable latch 5 and the fixed seat 3; an elastic member is connected to the cover plate 4, and the other end of the elastic member sequentially passes through the fixed seat 3 and the backing plate 2 and contacts the template 1.
[0024] It should be noted that by providing a movable latch 5 that is hinged to the fixed seat 3 and is clamped to the cover plate 4 on the fixed seat 3, and a first spring 6 is connected between the movable latch 5 and the fixed seat 3; an elastic member is connected to the cover plate 4, a punching die for a semiconductor automotive-grade silicon carbide power module is provided. The cover plate 4 can be quickly clamped by the movable latch 5, and the first spring 6 facilitates the ejection of the cover plate 4, facilitating the taking and placing of the product to be punched, realizing the quick closing of the cover plate 4, and facilitating the maintenance of the punching die, and the operation is safer.
[0025] As Figures 1 - 3As shown, a shock-absorbing block 7 for damping the closing operation of the cover plate 4 is installed on the fixed seat 3. It should be noted that through the setting of the shock-absorbing block 7, the closing operation of the cover plate 4 can be damped, enhancing the user's operation experience and ensuring the operation safety and service life of the device.
[0026] As Figures 1 - 3 shown, the shock-absorbing block 7 is made of an elastic material.
[0027] As Figures 1 - 3 shown, the elastic member includes a positioning bushing 8 fixedly connected to the template 1. An activity rod 9 is movably embedded in the positioning bushing 8. One end of the activity rod 9 is fixedly connected to the cover plate 4. A second spring 10 is sleeved on the activity rod 9, and the second spring 10 abuts against the positioning bushing 8. In the specific implementation process, the other end of the activity rod 9 is limited and movable within the positioning bushing 8.
[0028] It should be noted that when the cover plate 4 presses the punching product, by pressing the activity reed 5, the cover plate 4 moves away from the fixed seat 3 under the elastic force of the second spring 10, thereby realizing the rapid opening of the cover plate 4 and facilitating the taking and placing of the product to be punched.
[0029] As Figures 1 - 3 shown, the number of the activity reeds 5 and the first springs 6 is set to four, and the four activity reeds 5 are clamped at the four corners of the cover plate 4. It should be noted that through the setting of the four activity reeds 5, the connection stability between the cover plate 4 and the fixed seat 3 is improved.
[0030] As Figures 1 - 3 shown, the cover plate 4 is provided with a clamping notch 41, and the activity reed 5 is provided with a clamping portion 51 that is clamped and matched with the clamping notch 41. It should be noted that through the setting of the clamping portion 51 and the clamping notch 41, the activity reed 5 is clamped and matched with the cover plate 4, facilitating the fastening installation of the cover plate 4.
[0031] As Figure 3 shown, one side of the activity reed 5 is provided with an inclined pressing portion 52. It should be noted that through the setting of the pressing portion 52, it is convenient for the operator's finger to press the activity reed 5, so that the cover plate 4 is quickly ejected by the second spring 10.
[0032] As Figure 3 shown, the pressing portion 52 and the activity reed 5 are of an integrally formed structure.
[0033] In the specific implementation process, initially, under the clamping action of the activity reed 5, the cover plate 4 is locked on the fixed seat 3; by pressing the pressing portion 52 of the activity reed 5, the clamping portion 51 of the activity reed 5 is separated from the clamping notch 41 of the cover plate 4, and the cover plate 4 rises under the action of the second spring 10, and the cover plate 4 moves away from the fixed seat 3, facilitating the taking and placing of the product to be punched; since the first spring 6 plays a pulling role, it is convenient for the activity reed 5 to reset.
[0034] Working principle: A movable reed 5 that is hinged to a fixed seat 3 and is clamped to a cover plate 4 is provided. A first spring 6 is connected between the movable reed 5 and the fixed seat 3; an elastic member is connected to the cover plate 4, thereby providing a punching die for a semiconductor automotive-grade silicon carbide power module. The cover plate 4 can be quickly clamped by the movable reed 5, and the first spring 6 facilitates the ejection of the cover plate 4, facilitating the quick placement and removal of the product to be punched, realizing the quick closing of the cover plate 4, and facilitating the maintenance of the punching die, making the operation safer.
[0035] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
