Abstract
The utility model relates to a mould is made to forced air cooling diesel engine box, including last mould that has casting machine and the lower mould that has ejection mechanism, the die cavity outside of going up the mould is equipped with a plurality of slag traps, and slag trap and die cavity intercommunication pass through the overflow mouth intercommunication between 2 adjacent slag traps, the utility model discloses a communicateing each other between the slag trap, can improving the flow direction of metal liquid, the residue circulates between each slag trap, and it is incomplete to avoid the gaseous of some slag traps departments and residue to discharge, makes in gaseous and residue in the die cavity fully arrange the slag trap, eliminates cold shut, the gas pocket of foundry goods and presss from both sides the sediment, improves casting quality, has also prevented that the residue from leading to mould slider card dead in falling into the slider guide runner simultaneously.
Description
Technical field
The utility model relates to technical field of mold, especially a kind of air-cooled diesel engine engine housing mfg. moulding die.
Background technology
Existing aluminum alloy die-casting die generally includes upper die and lower die, the casting system be arranged on patrix, the ejecting mechanism and cooling system etc. be arranged on counterdie, have for the opening of side or the product of cavity for common, for the ease of ejecting of shaping rear product, the cavity of indent is set usually on patrix, counterdie arranges the core of evagination, when upper and lower mould is combined, between the cavity of patrix and the core of counterdie, form the die cavity of shaped article.When formed product and after cooling and shaping, upper and lower mould separately, product relies on that its cooling meat produces and between core Bao Moli and rests on counterdie, the longitudinal direction of product along mould is ejected, thus be separated with the core of counterdie finally by the ejecting mechanism on counterdie.When product has sidewise hole, then the frame for movement by Angle Pin or hydraulic jack one class carries out side core-pulling.
In order to get rid of and the residue reduced in foundry goods and pore, while design casting system, die casting also can arrange slag trap.Slag trap can hold the sluggish metal entering die cavity at first and the gas, the residue that are mixed in wherein, eliminates the cold shut of foundry goods, pore and slag inclusion, can also improve the local temperature of mould, to reach mold hot balance.But existing die casting slag trap is mutual independent, mutual disconnected structure, the residue in each slag trap and gas uneven, the quality of foundry goods is impacted.
Utility model content
The technical problems to be solved in the utility model is: in order to the slag trap solving existing die casting is not communicated with mutually, in each slag trap residue and gas uneven, affect the problem of casting quality, a kind of air-cooled diesel engine engine housing mfg. moulding die be provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of air-cooled diesel engine engine housing mfg. moulding die, comprise the patrix with casting system and the counterdie with ejecting mechanism, some slag traps are provided with outside the die cavity of described patrix, described slag trap is communicated with die cavity, is communicated with between adjacent 2 described slag traps by overfall.
Preferably, the dark 1-1.5mm of described overfall, long 20-25mm.
The beneficial effects of the utility model are, be interconnected between slag trap of the present utility model, the flow direction of molten metal can be improved, residue circulates between each slag trap, the gas at the slag trap place avoided and residue are discharged not exclusively, and the gas in die cavity and residue are fully discharged in slag trap, eliminate the cold shut of foundry goods, pore and slag inclusion, improve casting quality, also prevent residue simultaneously and fall in slide block guide runner and cause mould slide block stuck.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is upper die structure schematic diagram of the present utility model.
In figure: 1. die cavity, 2. slag trap, 3. overfall.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of air-cooled diesel engine engine housing mfg. moulding die as shown in Figure 1, comprise the patrix with casting system and the counterdie with ejecting mechanism, some slag traps 2 are provided with outside the die cavity 1 of described patrix, described slag trap 2 is communicated with die cavity 1, be communicated with by overfall 3 between adjacent 2 described slag traps 2, described overfall 3 dark 1-1.5mm, long 20-25mm.
Be interconnected between slag trap 2, the flow direction of molten metal can be improved, residue circulates between each slag trap 2, the gas at slag trap 2 place avoided and residue are discharged not exclusively, the gas in die cavity 1 and residue is made fully to be discharged in slag trap 2, eliminate the cold shut of foundry goods, pore and slag inclusion, improve casting quality, also prevent residue simultaneously and fall in slide block guide runner and cause mould slide block stuck.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
