Abstract
The utility model discloses a casting mold for a hammer head of crushing machine, and relates to the technical field of the casting of hammer heads of crushing machines. The casting mold comprises an upper mold and a lower mold, wherein the upper mold corresponds to the lower mold; a mold cavity is formed in the upper mold and the lower mold; an upper gate riser is formed in the left side of the upper mold; a channel is formed in the upper gate riser; the channel is communicated with the mold cavity; an exhaust hole (a) is formed in the right side of the upper gate riser; an exhaust hole (b) is formed in the right side of the exhaust hole (a); a lower gate riser is formed in the left side of the lower mold; the upper gate rise corresponds to the lower gate riser; the exhaust hole (a) and the exhaust hole (b) are communicated with the mold cavity; the left side of the mold cavity is fan-shaped. The casting mold for the hammer head of the crushing machine has the advantages of simple structure, no air bubbles and resource conservation; excessive air is exhausted by the exhaust holes, so that air holes are prevented; the content of air in liquid metal is reduced, the mechanical property of the hammer head is improved, the wear resistance of the hammer head is improved by the circular hammer head, and the service life of the hammer head is prolonged.
Description
Technical field
The utility model relates to grinder hammerhead casting technology field, is specifically related to a kind of grinder hammerhead casting mould.
Background technology
Grinder hammerhead is one of hammer mill kernel component, is arranged on the hammer axle of crusher rotor, and tup directly hits material in the time that disintegrating machine runs up, and finished breaking becomes suitable raw meal particle size.At present, tup generally adopts casting technique to obtain.Casting flaw is a great problem of puzzlement foundry enterprise always, and casting flaw solution is never good will affect the quality of foundry goods.In casting process, gas was not overflowed in time before molten metal crust, the hole class defect generating in foundry goods.In foundry goods, produce after pore, will reduce its effective bearing area, and around pore, can cause stress to concentrate and impact resistance and the fatigue resistance of reduction foundry goods.Pore also can reduce the compactness of foundry goods, the groove and the scar defect that form at cast(ing) surface.And general tup is square, and easily wearing and tearing, relatively waste resource.
Chinese utility model patent (Granted publication number is: CN 201815629 U) discloses single horizontal parting hammer die of metal mold, this patented technology is by adopting metal pattern to complete casting object, but this metal pattern does not have exhaust apparatus, and shaped article tup is square.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, grinder hammerhead casting mould of not producing bubble and economizing on resources, i.e. a kind of grinder hammerhead casting mould.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of grinder hammerhead casting mould, comprise upper die and lower die, described patrix is corresponding with counterdie, and patrix and counterdie are provided with die cavity, and patrix left side is provided with dead head, upper dead head inside has passage, passage communicates with die cavity, and upper dead head right side is provided with steam vent a, and steam vent a right side is provided with steam vent b, counterdie left side is provided with lower dead head, and upper dead head is corresponding with lower dead head.
Described steam vent a and steam vent b communicate with die cavity.Steam vent is got rid of unnecessary gas in time, prevents that foundry goods from producing bubble.
Described die cavity left side is fan-shaped.Circular tup is wear-resistant, longer service life.
Described patrix and counterdie are by guide pillar and the guide pin bushing incompatible accurate location that matches.
The beneficial effects of the utility model are: the utlity model has advantage simple in structure, that do not produce bubble and economize on resources, steam vent is got rid of unnecessary gas in time, prevent the generation of pore, reduce the air content in molten metal, improve the mechanical property of tup, circular tup strengthens the wearability of tup, improves the service life of tup.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
In figure, 1, steam vent a, 2, steam vent b, 3, upper dead head, 4, patrix, 5, passage, 6, lower dead head, 7, counterdie, 8, die cavity, 9, guide pin bushing.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of grinder hammerhead casting mould, comprises patrix 4 and counterdie 7, and patrix 4 is corresponding with counterdie 7, patrix 4 is provided with die cavity 8 with counterdie 7, patrix 4 left sides are provided with dead head 3, and upper dead head 3 inside have passage 5, and passage 5 communicates with die cavity 8, upper dead head 3 right sides are provided with steam vent a1, steam vent a1 right side is provided with steam vent b2, and counterdie 7 left sides are provided with lower dead head 6, and upper dead head 3 is corresponding with lower dead head 6.
Steam vent a1 and steam vent b2 communicate with die cavity 8, and die cavity 8 left sides are fan-shaped, and patrix 4 and counterdie 7 are by guide pillar and the guide pin bushing 9 incompatible accurate location that matches.
When work, by guide pillar, guide pin bushing 9, closed in patrix 4, counterdie 7 location, the upwards interior injection molten metal bath of the passage 5 of dead head 3, molten metal is at the interior cooling forming of die cavity 8, and unnecessary gas is got rid of from steam vent, can obtain high-quality tup.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
