Description
Technical field
The present invention relates to die cast metal former field, particularly relate to a kind of vertical cold pressing chamber die casting machine for die cast metal.
Background technology
Die cast metal is shaping is by the molten metal of melting at a higher pressure, at full speed be packed into compression mod die cavity, and molten metal is solidified in a high voltage state and forms the process of metal crimp foundry goods, it is one most effective in current all metal casting forming methods.Along with the development that die cast metal is shaping, the punch forming of die cast metal forming technique and injection-moulding plastic, metallic plate is listed as three large shaping systems.The shaping distinguishing feature of die cast metal is: can forming shape is complicated, wall is thin non-ferrous metal structural member, is a kind of high efficiency, high accuracy, high interchangeability, low consumed precision component forming technique.
Die casting machine is one of key element the most basic in Die Casting, metal crimp mold realizes die cast by the operation of die casting machine, kind and the model of die casting machine are a lot, in general, state of temperature according to compression chamber of die casting machine can be divided into heat pressing type die casting machine and cold pressure die-casting machine, and cold pressure die-casting machine is divided into vertical die-casting machine, full-vertical die casting machine and horizontal plunger die casting machine according to its version again.The feature of vertical cold pressing chamber die casting machine is: the pressing direction of injection punch head and the setting direction of sprue perpendicular, molten metal turnover right angle after, reinject die cavity, so be called vertical side pressure chamber.Vertical cold pressing chamber die casting machine structure relative complex of the prior art, when die casting completes, when drift moves up, cut off cast clout, but clout not special device goes its upper end from drift to release, extend the work period to a certain extent, reduce the operating efficiency of die casting machine.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of vertical cold pressing chamber die casting machine for die cast metal, and this die casting machine framework is simple, effectively can improve the operating efficiency of die casting machine.
The present invention is achieved through the following technical solutions:
A kind of vertical cold pressing chamber die casting machine for die cast metal, comprise low punch, molten metal, pressure chamber, upper punch, nozzle, trumpet assembly, compression mod, Connection Block, cut somebody's hair, clout, described pressure chamber is placed in vertical, low punch is slidably mounted in pressure chamber, upper punch and low punch centering, can contacting metal liquid when described upper punch moves down, molten metal is extruded, through nozzle, trumpet assembly and inject the die cavity of compression mod, described nozzle is connected to the side of pressure chamber and is connected with trumpet assembly, described Connection Block is arranged on the side, upper end of die casting machine housing, Connection Block is provided with and cuts somebody's hair, cut somebody's hair by push rod connection reciprocating hydraulic cylinder, moving back and forth thus driving the clout ejected by low punch of cutting somebody's hair to release by hydraulic cylinder.
As the preferred technical solution of the present invention, described nozzle is pyramidal structure, and the aperture area of connection trumpet assembly one end is greater than the aperture area away from connecting pressure chamber.
As the preferred technical solution of the present invention, the center line of described low punch, upper punch, pressure chamber is on same straight line.
Its operation principle is: after compression mod is closed, upper punch is promoted to the space above pressure chamber, and low punch then stops at the gating location blocking nozzle, blocks the passage of trumpet assembly, molten metal is injected pressure chamber; When upper punch moves down, and contacting metal liquid, low punch moves down, and opens the charging aperture of nozzle, and rests on this position.Upper punch continues depressed fast, molten metal is extruded, and through nozzle, trumpet assembly and inject the die cavity of compression mod, fills complete, after the pressure durations certain hour pressurize of upper punch, namely be raised, low punch then moves up, and ejects clout, cut somebody's hair and to release at the effect decline clout of hydraulic cylinder, after die casting cooling curing, open compression mod, and release die casting.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is reasonable in design, structure is simple, reduce the production cost of die casting machine; Cut somebody's hair by setting simultaneously, clout can be released from low punch rapidly, decrease the circulation timei of die casting machine work, improve the operating efficiency of die casting machine.
