Technical field
This utility model relates to die casting field, is specifically related to the upper die structure of a kind of motor lid.
Background technology
Die casting is a kind of metal casting technique, is characterized in utilizing the mold cavity metal to melting to apply high pressure.Mould typically processes with the higher alloy of intensity, some the similar injection mo(u)lding of this process.According to the difference of die casting type, cold chamber die casting and hot chamber diecasting can be divided into.Cold chamber die casting can be used, including the kirsite that aluminum, magnesium, copper and aluminum content are higher when die casting being not used to the metal of hot chamber diecasting technique.In such a process, need first metal molten to be fallen in an independent crucible.The most a number of motlten metal is transferred in an injection room the most heated or injection nozzle.By hydraulic pressure or mechanical pressure, these metals are injected among mould.Owing to needs are transferred into cold house motlten metal, the shortcoming of this technique maximum is that circulation time is the longest.Die casting is a requisite part in die-casting system, its main purpose is so that in metallic solution energy mould inside die cavity formation die casting machine, but during metallic solution injection enters die cavity, too fast and too early press-in die cavity always makes the air of mold cavity cannot discharge too much, in turn result in die casting and there is the defect such as pore, shrinkage cavity, all the more so especially for complicated motor lid.Form, at motor cover body, the problem that the one-body molded attachment structure Ye Shi manufacturer needs for being connected solve with housing simultaneously.
Utility model content
In view of the above, the purpose of this utility model is to provide the upper die structure of a kind of motor lid, avoids the appearance of pore, shrinkage cavity by optimizing lid upper die structure, the most incompatible with each set of molds guarantees the one-body molded of attachment structure.
A kind of upper die structure of motor lid, including die holder, described die holder centre position is provided with upper mold, the clamping block that described upper mold is arranged by both sides is fixed on die holder, the corner of described upper mold is respectively arranged with interior concave block, described upper mold interposition is equipped with circular protrusions, described circular protrusions top also sets up several stepped protruding blocks, surrounded by annular upper mold runner around described circular protrusions, and the circular protrusions left and right sides is also respectively provided with the left cell body for attachment structure molding, right cell body, it is additionally provided with on the downside of described circular protrusions and the sprue of upper mold flow passage, it is provided with cinder ladle on the upside of described circular protrusions, wherein left, right cell body is also provided with being respectively arranged with cinder ladle away from circular protrusions side, it is additionally provided with buffering die cavity between described sprue and annular upper mold runner, and sprue connects injection mouth.
The upper die structure of a kind of motor lid that this utility model provides can be further arranged to the described upper and lower two ends of left cell body and be separately provided for the upper and lower tringle of attachment structure molding, the described upper and lower two ends of right cell body are also separately provided for the upper and lower module of attachment structure molding, and described upper and lower module is additionally provided with protruding column respectively.
The upper die structure of a kind of motor lid that this utility model provides can be further arranged to arrange left and right cell body and be 2 away from the quantity of circular protrusions side cinder ladle.
It is 3 that the upper die structure of a kind of motor lid that this utility model provides can be further arranged to be arranged on the quantity of cinder ladle on the upside of circular protrusions.
Of the present utility model preferential and have the beneficial effect that
1, the design of die cavity is buffered between sprue and annular upper mold runner, make injection mouth die casting enter the molten metal in runner necessarily to buffer at buffering die cavity, then entered in each die cavity by upper mold runner, so that it is guaranteed that molten metal can flow in die cavity uniformly；
2, the cinder ladle that left and right cell body side and circular protrusions upper end are arranged so that the molten metal being mixed with gas or regulus is full of in cinder ladle, it is ensured that cannot occur pore, shrinkage cavity in die casting machine；
3, it is vertically disposed with tringle and module at left and right cell body, utilizes cell body and tringle or module to cooperate so that attachment structure can be formed on motor lid.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings preferred implementation of the present utility model is the most preferably described, wherein,
