A wedge-shaped surface is arranged on one side of the upward moving block. A limiting and guiding block for limiting through the wedge-shaped surface is arranged between the upward moving block and the downward moving block. The other side of the downward moving block away from the limiting and guiding block is matched with a cover plate arranged at the edge of the top of the outer frame.

[0007] Preferably, a second chute is arranged at the bottom of the outer frame. A driving slider capable of moving along the second chute is arranged at the bottom of the transmission block. A blind hole is arranged at one end of the driving slider. A spring is arranged inside the blind hole. A ejector rod with one end cooperating with the spring is arranged at the port of the blind hole. The other end of the ejector rod is arranged on an installation block at the front of the outer frame. A first chute arranged along it is arranged on the first inclined surface at the top of the transmission block. A forced return slider capable of moving along it and arranged at the bottom of the upward moving block is arranged inside the first chute.

[0008] Preferably, guide plates are respectively arranged between the transmission block, the upward moving block, the guiding block and the downward moving block and the outer frame, between the guiding block and the upward moving block and the downward moving block respectively, and between the transmission block and the downward moving block and the upward moving block respectively.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the utility model according to the attached Figures 1-5 illustrations:

[0018] The technical solutions of the utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0019] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] As Figures 1-5 shown, on the basis of the prior art, the first embodiment of the present utility model provides a part flanging mechanism, including an outer frame 2. A transmission block 5 is installed at the bottom inside the outer frame 2. The transmission block 5 is elastically matched with the outer frame 2. The top of the transmission block 5 is respectively connected to an upward movement block 7 and a downward movement block 4 installed inside the outer frame 2 through two inclined surfaces. One side of the upward movement block 7 is provided with a wedge surface. A limit guiding block 1 limited by the wedge surface is installed between the upward movement block 7 and the downward movement block 4. The other side of the downward movement block 4 away from the limit guiding block 1 is matched with a cover plate 3 installed at the top edge of the outer frame 2. The specific structure of the above elastic match will be described in detail below.

[0022] The bottom of the outer frame 2 is provided with a second chute 21. A driving slider 51 capable of moving along the second chute 21 is installed at the bottom of the transmission block 5. One end of the driving slider 51 is provided with a blind hole. A spring 52 is installed inside the blind hole. A push rod 55 whose one end is matched with the spring 52 is installed at the port of the blind hole. The other end of the push rod 55 is installed on the mounting block 21 at the front of the outer frame 2. A first chute 53 arranged along it is installed on the first inclined surface at the top of the transmission block 5. A forced return slider 54 capable of moving along it and installed at the bottom of the upward movement block 7 is arranged inside the first chute 53.

[0023] In this embodiment, guide plates 6 are respectively installed between the transmission block 5, the upward movement block 7, the guiding block 1, and the downward movement block 4 and the outer frame 2, between the guiding block 1 and the upward movement block 7 and the downward movement block 4 respectively, and between the transmission block 5 and the downward movement block 4 and the upward movement block 7 respectively. The guide plates 6 can be respectively installed on the contact surfaces of any of the above-mentioned individual components, so no detailed description will be given here.

[0024] Specific working process: When the mold moves downward, it drives the flanging mechanism to work. After the downward movement block 4 is stressed, the transmission block 5 moves to the right, and the return spring 6 starts to be compressed. The upward movement block 7 moves upward, and the flanging work is carried out. After the mold reaches the set closing height and moves upward, the return spring 6 returns, pushing the transmission block 5 to stop at the position limited by the cover plate 3. The forced return slider 54 drives the upward movement block 7 to move downward and reset, and so on for repeated movements.

[0025] Although the embodiments of the present utility model have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved.
