Example Embodiment
[0040] Example one
[0041] See figure 1 , The present invention discloses a pressing device of a fully automatic magnetic powder powder molding press, which includes a pressure frame, the two ends of the pressure frame are the frame top plate and the frame table panel respectively, and also includes an upper mold micro-release pressure keeping Device, lower mold device and guide pillar frame transmission mechanism;
[0042] The upper mold micro-release pressure holding device includes an upper template 02 and a pressure holding installation module 03; the upper template 02 is provided with an upper template cavity with a downward opening, and a sensor 10 is arranged in the upper template cavity; The press-mounting module 03 has a stepped cavity that penetrates up and down. The lower part of the stepped cavity is encapsulated with a mounting plate 13, and a guide pin 11 and a spring are slidably embedded in the stepped cavity; the spring 12 is sleeved on the guide pin 11, the uppe...
Example Embodiment
[0058] Example two
[0059] See Figure 2 to Figure 5 , A method for manufacturing a magnet blank capable of controlling the holding pressure and the micro-release of the pressure, which includes the steps of manufacturing the magnet blank by using the pressing device of the above-mentioned fully automatic magnetic powder powder molding press.
[0060] Further, it includes the steps of secondary pressure maintaining and tertiary pressure release; specifically, first, under the control of the automated PCL program, the switch button of the control box is activated, and under the action of the power source of the lower cylinder 09, the lower template 06 carries the lower female The mold 16 rises, and the lower mold core rod 17 is released to form the required mold cavity depth; secondly, a quantitative magnetic powder is added to the cavity of the lower female mold 16 through an automatic feeding device, and the magnetic powder is arranged in polarity under the radiation of a set mag...
