Described vacuum tank is provided with one.
As another kind of scheme more specifically, described vacuum tank is provided with more than two, and each vacuum tank is connected by pipeline.
The beneficial effects of the utility model are as follows:
(1) this kind of mould evacuator can adopt the hand push move mode to be external in injection machine/metal powder injection molding machine, perhaps directly be installed on injection machine/metal powder injection molding machine inside, reasonable in design is reliable, has reliable in quality simultaneously, long service life, fault rate is low, advantage such as function admirable, noise are low;
(2) after this mould evacuator and injection machine/supporting use of metal powder injection molding machine, effectively air, moisture or other decomposition gas in the mold cavity are taken away, and the part that processes is had the following advantages: a, elimination piece surface pore defect, promote surperficial fineness, improve parts density; B, make powder metallurgy blank material organize more sturdy closely, can reduce the bubble that produce degreasing sintered back; C, prolongation die life solve blind hole and lack material defect; D, enhance productivity, can create more profit margins;
(3) this kind of mould evacuator can directly be connected with the injection moulding machine, simple to operate, the mould that cooperates vacuum-pumping, under the control of machine computer program, section die vacuumizes function when realizing the action of appointment, thereby the flue gas that the aqueous vapor that forms with air in the mold cavity with by releasing agent and lubricating oil produce directly is extracted in the coupled vacuum tank (container), and gets rid of by pump.
