At this time, the bottom end of the female mold will be opened, and then the first lifting frame will continue to drag the female mold upward under the pull of the hydraulic cylinder. At this time, the upper male mold slides downward relative to the female mold. During the downward sliding process, the stamping template of the upper male mold will push out the powder formed inside the female mold, thereby achieving the effect of facilitating demolding.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that after the stamping is completed, the powder formed inside the female mold is tightly attached to the inside of the female film under the pressure of the hydraulic system and is difficult to remove. The overall idea is as follows:

[0030] In view of the problems existing in the prior art, the present invention provides a vertical stamping powder forming device, comprising a fixed frame 1, a first lifting frame 2 for lifting is slidably mounted on the fixed frame 1, and a second lifting frame 3 for lifting is slidably mounted on the fixed frame 1.

[0031] An upper male die 4 for stamping is fixed on the fixed frame 1 , a lower male die 6 for stamping is fixedly installed on the second lifting frame 3 , a female die 7 for stamping is fixedly installed on the first lifting frame 2 , and a plurality of stamping templates are fixedly installed on the upper male die 4 .

[0032] A plurality of stamping templates are fixedly mounted on the lower male mold 6, a fixing sleeve 5 is installed between the fixing frame 1 and the upper male mold 4, a guide rod 8 for guiding is evenly fixedly mounted on the bottom end of the first lifting frame 2, the guide rod 8 is slidably connected to the second lifting frame 3, the upper male mold 4 is aligned with the female mold 7, and the female mold 7 is aligned with the lower male mold 6.

[0033] Fixed frame 1: As the basic structure of the entire device, it provides support for the installation and sliding of other components;

[0034] The first lifting frame 2 slides under the action of the hydraulic cylinder, driving the female mold 7 to perform corresponding actions;

[0035] The second lifting frame 3 slides under the action of the hydraulic cylinder, so that the lower male mold 6 can be inserted into the inner part of the female mold 7, so that the female mold 7 completes the bottom sealing;

[0036] Upper male mold 4: fixedly connected to the fixed frame 1, moves relative to the lower male mold 6 and the female mold 7, and the powder inside the female mold 7 is punched and formed through multiple punching templates;

[0037] Card sleeve 5: fix the upper male mold 4 on the fixed frame 1;

[0038] Lower male mold 6: The installed stamping template cooperates with the female mold 7, blocks the bottom end of the female mold 7 during stamping, and opens the bottom end of the female mold 7 during demoulding;

[0039] Female mold 7: used to contain powder and complete the molding and demoulding of powder under the coordinated action of various components;

[0040] Guide rod 8: provides guidance for the first lifting frame 2 to ensure that the lower male mold 6 and the female mold 7 can be aligned during the sliding process.

[0041] Working principle:

[0042] The first step is to connect the first lifting frame 2 and the second lifting frame 3 to the hydraulic cylinder respectively. When in use, the first lifting frame 2 slides downward under the push of the hydraulic cylinder, so that the female mold 7 is sleeved on the stamping template of the lower male mold 6. The stamping template of the lower male mold 6 will block the bottom end of the female mold 7, and then pour the powder into the interior of the female mold 7. Then, the first lifting frame 2 and the second lifting frame 3 are driven by the hydraulic cylinder to slide upward at the same time, so that the stamping template of the upper male mold 4 can be inserted from the top of the female mold 7 into the interior of the female mold 7. Under the action of the pressure of the hydraulic cylinder, the powder inside the female mold 7 will be stamped and formed.

[0043] In the second step, the second lifting frame 3 will slide downward and reset under the pull of the hydraulic cylinder, so that the stamping template of the lower male mold 6 can be separated from the female mold 7. At this time, the bottom end of the female mold 7 will be opened, and then the first lifting frame 2 will continue to drag the female mold 7 upward under the pull of the hydraulic cylinder. At this time, the upper male mold 4 slides downward relative to the female mold 7. During the downward sliding process, the stamping template of the upper male mold 4 will push out the powder formed inside the female mold 7 to complete the demolding, and then the first lifting frame 2 will be reset under the action of the hydraulic cylinder.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
