[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below by combining with the drawings and specific embodiments.
[0022] A stamping die lower die comprises Figs. 1-3 , comprising a lower die plate 10, two lower die feet 20 installed side by side and spaced apart on the lower die plate 10, a lower die base 30 installed on the two lower die feet 20, an elastic element 40 (preferably a nitrogen spring) installed on the lower die base 30, a pressure plate 50 and a pad 60 installed on the elastic element 40. The above structure is the conventional structure of the existing lower die, and specific details will not be repeated.
[0023] The space between the lower die base plate 10 and the lower die seat 30 and between the two lower die pads 20 is a cavity 70, and the height of the cavity 70 is greater than the thickness of the forklift fork leg 90. The lower die seat 30 is provided with a avoiding hole 31, the top end of the pad 60 is connected to the bottom of the pressing plate 50, and the bottom end of the pad 60 passes through the avoiding hole 31 and is located in the cavity 70. The bottom end of the pad 60 is located at the top of the cavity 70 when the mold is opened, and is in contact with the top surface of the lower die base plate 10 when the mold is closed.
[0024] The bottom dead structure of the traditional lower die pressing plate 50 occupies the cavity between the lower die seat 30 and the lower die base plate 10, which makes the cavity occupied by the bottom dead structure, and the forklift fork leg 90 carries the lower die in the cavity. In this application, the pad 60 is not directly connected to the lower die base plate, and when the mold is opened (not in use), the bottom end of the pad 60 is located at the top of the cavity 70 under the action of the elastic element 40, and when the mold is closed, it moves downward under the pressure of the upper die to contact the top surface of the lower die base plate 10. When it is necessary to carry, the bottom end of the pad 60 is located at the top of the cavity 70, and there is still enough space between the lower die base plate 10 and the lower die seat 30, so that the forklift fork leg 90 can be inserted into the space to carry the lower die, which facilitates carrying, shortens the carrying time and improves the carrying efficiency.
[0025] It should be noted that the height of the pad 60 should be matched with the height of the lower die pad 20 and the die seat.
[0026] In this embodiment, the bottom of the lower die seat 30 is provided with a fork leg matching block 80 located in the cavity 70, and the distance between the bottom surface of the fork leg matching block 80 and the top surface of the lower die base plate 10 is greater than the thickness of the forklift fork leg 90. By setting the fork leg matching block 80, when the forklift is inserted into the cavity 70, the lower die is supported by the fork leg matching block, and the forklift fork leg 90 does not contact the lower die seat 30, reducing the wear of the lower die seat 30.
[0027] Specifically, the fork leg matching block 80 has two, and the two fork leg matching blocks 80 are respectively arranged at the two ends of the lower die seat 30. In this way, when carrying, the forklift fork leg 90 only contacts the two fork leg matching blocks 80 and does not contact the lower die seat 30, reducing the wear of the lower die seat 30.
[0028] Further, the fork leg matching block 80 is a rectangular block, and the length thereof is matched with the width of the cavity 70, which can ensure the contact area of the fork leg and the fork leg matching block 80 and improve the carrying stability.
[0029] In this embodiment, the bottom surface of the pad 60 is higher than the bottom surface of the fork leg matching block 80 when the mold is closed, which can avoid interference between the fork leg and the pad 60.
[0030] In this embodiment, the fork leg matching block 80 is detachably connected with the lower die seat 30, which facilitates the maintenance of the fork leg matching block 80.
[0031] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation manners of the present application. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made. Here, it is not necessary and also impossible to enumerate all the implementation manners. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
