Description
Technical field
The utility model belongs to field of mechanical technique, relates to the mould control apparatus of a kind of fine powder press molding machine, particularly fine powder press molding machine.
Background technology
Its manufacturing process of workpiece that adopts powder die-casting to form is simple, manufacturing cost is lower.Therefore, fine powder press molding machine is extensive use of in machining.
Usually, the core rod in the fine powder press molding machine is arranged on the table top, in case powder stock is sent into the core rod place, and more just can be with the workpiece press forming by the staking punch that presses to the core rod place.A kind of " powder die casting machine " that for example China Patent No. 01231180.4 provides, it comprises a bent axle that is connected with power section, the bottom of bent axle is provided with ram, the bottom of last ram is provided with the upper punch that is used for the punching press powder, bottom corresponding to upper punch is provided with middle mould, just can will place the powder die-casting in the mould to be shaped in the mould in upper punch presses to.Simultaneously the side at bent axle also is provided with one second cam, when need the workpiece that die casting is good withdrawing from, presses down and just can realize moving back mould by the tringle that moves back that is connected with second cam.
As can be seen, can easily the workpiece that has suppressed be withdrawed from after above-mentioned die casting machine suppresses workpiece.But, when above-mentioned die casting machine withdraws from workpiece, be by second cam, move back cooperations such as tringle, pivot block and make low punch that the workpiece that processes is ejected.Obviously, it is too complicated that this moves back mold mechanism, makes machine cost higher.Obviously, safeguard the difficulty that also seems.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, provides a kind of stability in use good, the mould control apparatus of fine powder press molding machine simple in structure.
The purpose of this utility model can realize by following technical proposal: a kind of mould control apparatus of fine powder press molding machine; be arranged on the table top place of fine powder press molding machine and be positioned at the staking punch below of fine powder press molding machine; it comprises a mould seat; on the mould seat core rod is housed; it is characterized in that described table top is provided with guide rail, above-mentioned mould seat is placed on the guide rail; and the mould seat links to each other with one group of transmission mechanism, and the mould seat is reciprocatingly slided along guide rail.
The staking punch of fine powder press molding machine presses to the core rod place, just the powder stock that is positioned at the core rod place can be compressed to workpiece.
In the mould control apparatus of this fine powder press molding machine, because transmission mechanism can drive the mould seat and slide on guide rail.Therefore, compacting during workpiece the mould seat slide into staking punch under, that is to say this moment core rod be positioned at staking punch under, the staking punch after pressing down just can be pressed into workpiece with the powder stock that is loaded on the core rod place.
After the mould seat slides and shifts out under the staking punch, just can be easily the workpiece at core rod place is withdrawed from or in core rod, annotate powder stock.
In the mould control apparatus of above-mentioned fine powder press molding machine, described transmission mechanism is made up of rotating disk and connecting rod, and rotating disk links to each other with actuating unit, and an end of connecting rod is hinged on the non-central location of rotating disk, and the other end is hinged on the above-mentioned mould seat.
