Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, the mechanism for synchronously retracting the upper die pressing plate and the lower die pressing ring comprises a swinging block assembly 1, a resetting assembly 2 and a driving assembly 3.
The swing block assembly 1 comprises a swing block fixing part 11, a first locking part 12 and a swing block 13. The swing block assembly 1 is fixedly connected to the lower die blank holder, and the swing block assembly 1 comprises a swing block fixing part 11 and a swing block 13 which is rotatably arranged on the swing block fixing part 11. The swing block assembly 1 further comprises a first locking portion 12, the first locking portion 12 is used for connecting the swing block fixing portion 11 and the swing block 13, the first locking portion 12 serves as a rotation center, and the swing block 13 rotates relative to the swing block fixing portion 11.
The driving assembly 3 includes a driving member fixing portion 31 and a second locking portion 32 telescopically disposed in the driving member fixing portion 31.
The driving component 3 is fixed on the lower die holder. The mould descends, and the second locking portion 32 in the driving assembly 3 pushes the swing block 13 to reach the vertical position, and the upper mould pressing block support contacts and presses the upper portion of the swing block 13 to form rigid connection.
And (3) opening the die, wherein the second locking part 32 is under the action of the second elastic part 33, the second elastic part 33 usually uses a nitrogen spring, the pressure of the nitrogen spring is far greater than the spring force of the first elastic part 22, and the swing block 13 rigidly connected with the lower die blank holder in the jacking process synchronously jacks the upper die blank holder. The process needs to be synchronously jacked, otherwise, the lower die material pressing plate is jacked, the middle of the upper die is still pressed, and the material pressing plate top lifted around the product deforms.
And the upper die material pressing plate is synchronously jacked up by the swing block 13 which is rigidly connected in the jacking process of the lower die blank holder to completely release the stroke of the upper die nitrogen spring. Then the upper die base moves upwards, the rigid connection is disconnected, the swing block 13 is ejected outwards by the first elastic piece in the reset assembly, and the swing block 13 rotates outwards to reset.
