Description
Technical field
It is long more particularly, to a kind of powder injection forming the utility model relates to powder compacting, injection molding technology field
The full-automatic numerical control dry powder hydrostatic press of bar product class part.
Background technique
Powder pressing technology (Powder Injection Molding, abbreviation PIM) is to draw compression molding forming technology
A kind of advanced near-net-shape technology for entering powder metallurgy can be solved using PIM technique high-volume manufacture elongate body class thin part
High material consumption that certainly tradition machinery manufacturing process faces, machining period be more, unstable quality and cannot form mass production
Deng problem.Machining deformation, material can be greatly reduced using the two-way pressing process high-volume manufacture strip sheet class part of PIM
Expect that utilization rate up to 99%, reduction processing cost, improves Product Precision, efficiency is than ten times of raising of tradition compacting or more.But PIM work
Skill be applied to manufacture elongate body three-D space structure part when carrying out powder compacting, although first is that charging relatively accurately, by
Mould bases face is flushed with or slightly higher than in charge level and mould bases face, thus in compacting, charge level powder is easy to overflow, and cannot be formed under powder
Shifting and progressive charging, are not good powders for high product and mobility, and the accuracy that charges and uniformity can reduce, thus
It is to influence product quality；Second is that compacting tool set is not easy to cavity dimension adjustment in the past, many types of system of one mould of similar product cannot be formed
Modeling formula, improves pressing cost and die manufacturing cost.
Utility model content
For it is above-mentioned the problems of in the prior art, the utility model provide it is a kind of can both have been formed powder move down and
Progressive charging, it is ensured that product quality, and mold cavity size adjusting can be carried out, the compacting of more specification products is adapted to, compacting is reduced
The full-automatic numerical control dry powder hydrostatic press of cost and die manufacturing cost.
The technical problems to be solved in the utility model is adopted the technical scheme that: a kind of full-automatic numerical control dry powder hydrostatic press
Including upper beam, moved cross beam, lower beam and the feed box being connected with column, it is provided with master cylinder on the upper beam, it is described
It is provided with master plate on the working beam of master cylinder, upper punch is provided on master plate, lower oil cylinder, institute are provided on the lower beam
The piston rod upper end stated in lower oil cylinder is connected with mould bases, and mold is provided in mould bases, and low punch, the piston are provided on mould bases
Bar lower end has threaded shaft section and passes through lower oil cylinder, is movably set with driven gear, the driven gear on the threaded shaft section
It is meshed with driving gear, the driven gear lower end surface is supported on two sliding blocks that can control relative movement, the thread spindle
Displacement digital sensor is provided in section.
Mold in mould bases described in the utility model includes the fixed form of shape forming cavity, the activity opposite with fixed form
Template and the Side Template between fixed form and collapsible form, the collapsible form have inclined-plane, and the collapsible form is logical
Crossing inclined-plane can match with the inclined plate moved left and right, and inclined plate movement can make the width of type chamber change, to reach adjustment type
The purpose of chamber width.
The Side Template is fixed on mould bases with adjusting screw, and unclamping adjusting screw Side Template can move left and right on mould bases
It is dynamic, to achieve the purpose that adjustment type cavity length.
In charging, driven gear lower end surface is supported on sliding block the utility model, after charging, electronic starting, and driving tooth
Wheel rotation drives the rotation of driven gear up time, increase threaded shaft section rotation, and driven gear rises, and mould bases is driven to rise simultaneously,
When charge level position is constant, mould bases rises, and makes the high discharge feed side of plane on mould bases, realizes that powder moves down, while passing through displacement number
The effect of sensor is ramped up and is declined by threading path the variation of displacement, accurately obtains raise-position on the lower end surface of driven gear
Shifting amount, by the rising of screw thread involute, it can be achieved that progressive charging.
The utility model on lower beam first is that by being provided with by sliding block, cylinder, driven gear, driving gear, servo electricity
The mechanism of machine, displacement digital sensor composition is made charging be able to achieve powder and is moved down, realizes that charging is progressive and real by the mechanism
It now crosses and owes amount charging, improve the mobility and uniformity of powder, improve product quality；Second is that the cavity dimension of whole set of die can be into
Any adjustment of row, realizes repeatedly using for the more specifications of identical product, to abrasion mold, need to only carry out plain grinding and polishing can
It reuses, reduces number of molds, reduce the manufacturing expense of mold.
