Description
Technical field
This utility model belongs to compression mod field, is specifically related to a kind of compression mod processing top cover.
Background technology
Die casting, also known as compression casting, belongs to the category of casting technique, is the one in Special Processes of Metal Castings technique.Extrusion process is profit
With compression mod, molten condition alloy is poured into the pressure chamber of die casting machine, under pressure, is filled in compression mod with high speed
Intracavity, and under high pressure make molten alloy cooled and solidified obtain foundry goods.
Top cover is that one has thin-walled and baroque product, and in prior art, notification number is the special of CN204308164U
Profit (publication date is 2015.05.06) discloses a kind of top cover die casting, and this top cover die casting includes cover half and moves
Mould, is formed between described cover half and described dynamic model for the molding cavity of top cover described in molding and is communicated in described molding cavity
And enter the running channel of described molding cavity for metal liquid, described molding cavity have be positioned on the downside of described molding cavity and for
The lower inclination tract of the inclination thin-walled on the downside of top cover described in molding, described running channel is communicated in the bottom of described lower inclination tract, institute
State running channel and described lower inclination tract to tilt towards the same side, and described running channel to the water conservancy diversion direction of described metal liquid with described under
Tilt the tract angle to the water conservancy diversion direction of described metal liquid more than or equal to 0 ° and less than 90 °.
But above-mentioned top cover die casting has a following weak point:
1, the molding cavity of this mould is once only capable of preparing a top cover, and working (machining) efficiency is relatively low；
2, the spreader of this mould is fixedly mounted on the bottom of dynamic model, and such structure is difficult to ensure that the structure of spreader is strong
Degree so that this spreader is difficult in adapt to process the high pressure needed for two or more top cover.The structure of Gu Fenliuzhuichu also limit
This mould realizes highly efficient die-casting process.
Based on this, applicant considers that designing one can disposably process two top covers, the higher compression mod of working (machining) efficiency.
