A discharge translator is installed on one side of the working platform 1, and a support frame 7 is movably installed on the discharge translator. The upper shaping die 6 is installed on the support frame 7 through a first lifting cylinder 8. The first lifting cylinder 8 is a structure used in the prior art. The finished product is directly purchased according to the stroke and pressure used. A suction assembly is arranged on the upper shaping die 6.

[0011] The working process of the device is as follows: the MIM parts to be shaped are introduced into the vibration plate 2. During the vibration process, the vibration plate 2 can arrange the MIM parts in sequence and discharge them from the two discharge ports. The arranged MIM parts are transferred to the receiving table 4 through the discharge channel. At this time, the material transfer component can transfer the two MIM parts on the receiving table 4 to the lower shaping mold 5 at the same time. The lower shaping mold 5 is driven by the lower mold translator to the bottom of the upper shaping mold 6. The upper shaping mold 6 is driven by the first lifting cylinder 8 to move downward and contact the lower shaping mold 5. The MIM parts can be shaped in the process of contact and compaction. After the shaping is completed, the material is sucked. The assembly absorbs the MIM parts, and the discharging translator can move the MIM parts to the receiving trough 9; the structure and layout of the device is reasonable, the investment cost is low, and the coordinated use of the vibration feeding mechanism, the receiving mechanism, the moving mechanism, the shaping mechanism and the receiving trough does not require manual participation, and can realize the automatic feeding, automatic shaping and automatic discharging of two MIM products, reduce the labor intensity of manual labor, improve the degree of automation, and thus improve the production efficiency. Moreover, the automatic shaping of two MIM parts can be realized at the same time, which can greatly improve the production efficiency and effectively increase the production output, and is convenient to use.

When it moves to the top of the material receiving table 4, the third lifting cylinder 13 drives the positioning plate 14 to move downward. When it moves to the point where the suction nozzle contacts the MIM part, the suction disk 15 inhales air, and the suction nozzle moves the MIM part independently. The translation driver can control the material transfer slide 12 to drive the MIM part to move to the lower shaping mold 5, and then the suction disk 15 deflates, and the MIM part can be transferred to the lower shaping mold 5 for shaping. Repeatedly, the MIM parts can be transferred between the receiving table 4 and the lower shaping mold 5; preferably, the material transfer translator includes a rodless cylinder 16, a connecting rod 17 and a fixed block 18. The rodless cylinder 16 is a structure used in the prior art and can be directly purchased.
