Alternatively, the main pressure chamber 120 may be substantially rectangular parallelepiped, and the direction of the long side thereof is the direction in which the billet is pressed by the pressing mechanism.

The pre-pressure chamber 130 is horizontally communicated with the main pressure chamber 120, and a communication port 121 is formed at the communication position of the pre-pressure chamber 130 and the main pressure chamber 120. The pre-pressing cavity 130 is used as a container for primarily pressing the blank, and the loose blank is pressed into a solid block with higher density in the pre-pressing cavity and then horizontally pushed into the main pressing cavity through the communication opening 121 for further pressing and forming. Alternatively, the pre-load chamber may be substantially rectangular parallelepiped.

The first pressing portion 151 is provided opposite to the communication port 121, and can press the billet in the preliminary press chamber 130 toward the communication port 121 by the driving of the first driving device 152. The first driving device may be a pneumatic cylinder, a hydraulic cylinder or other power device capable of providing linear driving force, and may be connected to the first pushing part through a driving rod.

The forming end 160 and the second pressing mechanism 170 are respectively disposed on two opposite sides of the main pressure chamber 120, and the second pressing mechanism 170 has a second pressing portion 171 and a second driving device 172. In the embodiment of the present disclosure, the second pushing part 171 can move to the position where the communication port 121 is located to close the communication port 121 by the driving of the second driving device 172. As will be understood by those skilled in the art, the second pressing portion 171 can close the communication port 121 by setting the area of the side of the second pressing portion 171 that contacts the communication port 121 to be not smaller than the area of the communication port 121. The second driving device may be a pneumatic cylinder, a hydraulic cylinder or other power device capable of providing linear driving force, and may be connected to the second pushing part through a driving rod.

In some embodiments, the forming opening has a horizontal length greater than a vertical height, which can be used to produce a sheet-like shaped body.

According to one or more embodiments provided by the present disclosure, the method for manufacturing a molded body using the apparatus for manufacturing a molded body 100 includes a feeding process, a pre-pressing process, and a molding process, which are specifically described as follows.

In the disclosed embodiment, the billet within the primary pressure chamber 120 may be a plurality of pre-compressed batches of billets. Since the time taken for the preliminary pressing process is generally shorter for one batch of the material than for the forming process, the second pressing portion 171 pushes the preliminary pressed material located at the communication port 121 toward the forming end after each preliminary pressing process is completed, thereby making room for the next batch of the preliminary pressed material. Thus, after the steps are repeated, the main pressure cavity can contain a plurality of batches of blanks pre-pressed and compressed.
