[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides a large-capacity powder feeding mechanism of a powder molding press, including a powder box 11, a powder box advance and retreat drive device 12, a powder box upper cover plate 13, a front powder box pressing cylinder 14, a rear powder box pressing cylinder 15, a pressing cylinder mounting bracket 16, a material barrel 17, a material barrel mounting bracket 18, a feed pipe 19, a material pipe adapter 110, an adapter fixing plate 111 and a sealing plate 112. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the powder box 11 can be set as a square box structure with upper and lower openings and a hollow interior, and its capacity is large. The powder box upper cover plate 13 is installed on the top of the powder box 11. The front top of the powder box upper cover plate 13 is provided with a powder box feed port connected to the inside of the powder box 11. The rear end of the powder box upper cover plate 13 extends horizontally backward from the rear side of the powder box 11. The length of the powder box upper cover plate 13 is greater than the front and rear movement distance of the powder box 11. In this embodiment, the powder box upper cover plate 13 not only serves as a cover plate, but also serves as a material stop.

[0021] like Figure 2 As shown, the powder box advance and retreat driving device 12 is installed at the rear side of the powder box 11 and is transmission-connected to the powder box 11 so as to drive the powder box 11 to move forward and backward. The powder box advance and retreat driving device 12 can preferably be set as a cylinder.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the downward pressure cylinder mounting brackets 16 are located on the left and right sides of the powder box 11, the upper ends of the front powder box downward pressure cylinder 14 are respectively hinged to the two downward pressure cylinder mounting brackets 16, the lower ends of the front powder box downward pressure cylinder 14 are respectively hinged to the front ends of the side surfaces of the powder box 11, the upper ends of the rear powder box downward pressure cylinder 15 are respectively hinged to the two downward pressure cylinder mounting brackets 16, and the lower ends of the rear powder box downward pressure cylinder 15 are respectively hinged to the rear ends of the side surfaces of the powder box 11. Under the downward pressure of the front powder box downward pressure cylinder 14 and the rear powder box downward pressure cylinder 15, the powder box 11 can slide on the surface of the master mold lifting plate of the powder molding press, thereby reducing the occurrence of powder leakage from the powder box.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the material barrel 17 is mounted above the powder box upper cover 13 through the material barrel mounting bracket 18, the adapter fixing plate 111 is connected between the two downward pressure cylinder mounting brackets 16 and is located between the material barrel 17 and the powder box upper cover 13, the material pipe adapter 110 is set in a circular ring shape, and the material pipe adapter 110 is installed at the hole position of the adapter fixing plate 111. The upper end of the feed pipe 19 is connected to the bottom discharge port of the material barrel 17, and the lower end of the feed pipe 19 is connected to the feed pipe adapter 110. Among them, the feed pipe 19 can be preferably set as a telescopic feed pipe.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing plate 112 is installed at the bottom of the material tube adapter 110 and is located above the powder box upper cover 13. The sealing plate 112 is provided with a sealing plate dropout port that can be connected to the powder box feed port of the powder box upper cover 13. The position of the sealing plate dropout port corresponds to the position of the center hole of the material tube adapter 110.

[0025] like Figure 1 and Figure 2 As shown, a feed pipe tee 113 may be provided above the feed port of the barrel 17, and the bottom discharge port of the feed pipe tee 113 may be connected to the top feed port of the barrel 17 through a feed pipe 119. The feed pipe 119 may preferably be a telescopic feed pipe.

[0026] Since a large amount of powder is required each time when pressing a super-large product, in order to increase the powder delivery speed and efficiency to match the pressing of super-large products, such as Figure 4 and Figure 5 As shown, a screw feeder 114 may be further provided, and one of the inlets of the feed pipe tee 113 may be connected to the outlet of the screw feeder 114. When feeding powder, the internal propeller of the screw feeder 114 can quickly transport the powder entering the screw feeder 114 to the feed pipe tee 113 and the material barrel 17, which can solve the problem of a long waiting time for feeding powder in the prior art.

[0027] like Figure 1 and Figure 2 As shown, in order to facilitate the forward and backward movement of the powder box, the left and right sides of the powder box 11 can also be provided with powder box limit bars 118 respectively. The powder box limit bars 118 can limit the left and right sides of the powder box to prevent the powder box from shifting.

[0028] like Figure 2 As shown, a residual powder recovery funnel 117 may also be provided below the bottom of the powder box 11 .

[0029] Before filling powder, the powder box 11 is in the initial position, and the sealing plate drop-out opening of the sealing plate 112 is connected to the powder box feed opening of the powder box upper cover plate 13. At this time, the powder in the barrel 17 can drop into the powder box 11 through the feed tube 19, the tube adapter 110 and the sealing plate drop-out opening of the sealing plate 112. When powder needs to be filled, the powder box advance and retreat drive device 12 drives the powder box 11 to move forward. At this time, the powder box feed opening of the powder box upper cover plate 13 will be staggered with the sealing plate drop-out opening of the sealing plate 112, and the rear end of the powder box upper cover plate 13 will block the sealing plate drop-out opening of the sealing plate 112 to prevent the powder from continuing to fall. When the powder box 11 moves to the cavity (square) position of the mother mold of the powder molding press, the powder in the powder box 11 will be filled downward into the cavity of the mother mold.

[0030] In summary, the large-capacity powder feeding mechanism of the powder molding press of the utility model has a large powder filling amount, good stability, and high efficiency, and can assist the powder molding press in pressing super-large products.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
