A stamping top seat 3 is fixedly provided at the top of the support rod 2, and an upper die pressing seat 4 is slidably sleeved on the support rod 2. The stamping device for forming thermocomposite materials also includes:

[0044] The two connecting parts 5 located between the upper die holder 4 and the stamping top holder 3 are used to strengthen the connection between the upper die holder 4 and the stamping top holder 3.

[0045] Strong Alliance Department 5 includes:

[0046] The lower retaining block 56 is fixed to the top of the upper mold pressing base 4.

[0047] The bottom of the stamping top seat 3 is provided with a spring groove 54, which is fixed to the bottom of the two bearing seats 51.

[0048] Rotate the horizontal shaft 52 which is sleeved between the two bearing seats 51.

[0049] The upper buckle 53 and the lower buckle 56 are fixed on the horizontal axis 52 in the shape of a "7". The upper buckle 53 is L-shaped and the horizontal opposing surfaces of the upper buckle 53 and the lower buckle 56 are inclined surfaces. When the upper mold pressing seat 4 is reset, the upper buckle 53 and the lower buckle 56 are locked together.

[0050] A torsion spring 55 is sleeved on the end of the horizontal shaft 52, and the two ends of the torsion spring 55 are fixed on the horizontal shaft 52 and the bearing seat 51, respectively.

[0056] In this embodiment, the stamping device for hot composite material forming further comprises:

[0057] A lower die 7 fixed to the top of the stamping base 1.

[0058] A pneumatic stamping part 6 for assisting the stamping part in the lower die 7 to be demolded.

[0059] The pneumatic stamping part 6 comprises:

[0060] A connecting strip 601 slidably sleeved between two adjacent supporting rods 2.

[0062] The main rack 603 is sleeved on the rack hole 604 arranged on the top of the stamping base 1, and the top of the main rack 603 is fixed to the bottom of the connecting strip 601.

[0063] When the upper die holder 4 moves downward by a certain height, the connecting strip 601 can be contacted, and the connecting strip 601 is synchronously moved downward by the pushing, and the main rack 603 is synchronously moved to be inserted into the rack hole 604, until the upper die holder 4 is docked with the lower die 7 to stop, at the same time, the spring 602 is extruded and shrunk to accumulate elastic force, when the upper die holder 4 moves upward to reset, the elastic force accumulated by the spring 602 synchronously pushes the connecting strip 601 to move upward to reset, until the connecting strip 601 is separated from the upper die holder 4, in the process, the connecting strip 601 synchronously moves upward with the main rack 603, and the main rack 603 is taken out of the rack hole 604 by a certain height.

[0064] In the embodiment, the pneumatic stamping die part 6 further comprises:

[0065] The piston column 606 is fixedly connected with the piston groove 605 arranged on the top of the stamping base 1.

[0066] The piston sleeve 607 is sleeved on the outside of the piston column 606 and is located in the piston groove 605.

[0067] The air guide groove 608 is vertically arranged on the top of the piston column 606 and is communicated with the outside of the stamping base 1 and the piston sleeve 607.

[0068] The air guide pipe 610 is fixed on the stamping base 1, and one end of the air guide pipe 610 is communicated with the inside of the lower die 7.

[0070] The pneumatic stamping die part 6 further comprises a one-way air inlet valve arranged at one end of the air guide groove 608, and a one-way air outlet valve arranged between the air guide pipe 610 and the air guide groove 609.

[0073] When the connecting strip 601 moves downward, the piston sleeve 607 moves upward by the power transmission of the transmission teeth 612, so that a negative pressure vacuum state is formed between the piston sleeve 607 and the piston column 606. Since the air guide groove 608 is communicated with the space between the piston sleeve 607 and the piston column 606, a negative pressure vacuum state is also formed in the air guide groove 608. Under the action of the air pressure difference between the inside of the air guide groove 608 and the outside of the stamping base 1, the one-way air inlet valve is opened, air outside is sucked into the space between the piston sleeve 607 and the piston column 606, so that more air is accumulated between the piston sleeve 607 and the piston column 606. When the connecting strip 601 moves upward, the piston sleeve 607 moves downward by the power transmission of the transmission teeth 612 and squeezes the air accumulated between the piston sleeve 607 and the piston column 606, so that the air pressure is increased. Since the air guide pipe 610 is communicated with the space between the piston sleeve 607 and the piston column 606 through the one-way air outlet valve, the air guide groove 608 and the branch air groove 609, under the action of the air pressure difference between the inside and outside of the one-way air outlet valve, the one-way air outlet valve is opened, and high-pressure gas is pressed into the lower die, the stamping part is pushed by the air pressure, so that the stamping part is separated from the inner wall of the lower die, the auxiliary stamping part is demolded, and the demolding difficulty of the stamping part is reduced.

[0074] The above only describes preferred embodiments of the present application, and parts not described in the present application can be realized by using or referring to existing technology. Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the protection scope of the present application.
