In order to achieve the above purpose, the utility model adopts the following technical scheme: a die feed inlet comprises a sprue bush and a sprue spreader, wherein the sprue bush is matched with the sprue spreader; the sprue spreader comprises a cylindrical portion and a plurality of bosses, wherein the bosses are arranged above the cylindrical portion, grooves are formed in the bosses, first grooves are formed in the cylindrical portion, the grooves and the first grooves are matched to form channels, and bulges are arranged in the middle of the inner portions of the channels.
As a preferred technical solution of the present invention: the groove comprises a curved upper part and an inclined lower part, and the radius of the upper curved surface is gradually reduced from top to bottom; the shape of first recess is loudspeaker form, and its opening is outwards crescent from inside.
As a preferred technical solution of the present invention: the upper end of the protrusion is curved and matched with the upper part of the groove, the middle of the protrusion is inclined and matched with the lower part of the groove, and the lower end of the protrusion is trapezoidal.
As a preferred technical solution of the present invention: the number of the bosses is two, and the two bosses are oppositely arranged on the upper part of the cylindrical part.
As a preferred technical solution of the present invention: the sprue bush comprises a base, a cylindrical feed inlet is arranged above the base, and a plurality of reinforcing ribs are arranged between the feed inlet and the base; two opposite clamping grooves are formed below the cylindrical part.
The utility model discloses following beneficial effect has:
1. the arrangement of the grooves and the first grooves enables molten metal not to directly impact an internal cavity, pressure loss during die casting is reduced, defects of casting shrinkage cavity, under-casting and the like are reduced, and casting quality is remarkably improved.
2. The arrangement of the bulges ensures that the speed of the molten metal tends to be uniform and balanced, and the casting quality is improved; the arrangement of the plurality of bosses can adapt to a plurality of casting runners, and the application range is enlarged.

Detailed Description
In order to make the objects and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-4, an embodiment of the present invention provides a mold feed inlet, which includes a sprue bush and a spreader cone 1, wherein the sprue bush is matched with the spreader cone 1; the sprue bush comprises a base 7, a cylindrical feed port 8 is arranged above the base 7, a plurality of reinforcing ribs 9 are arranged between the feed port 8 and the base 7, and the firmness of the feed port 8 is improved due to the arrangement of the reinforcing ribs 9; meanwhile, as shown in fig. 5, the sprue bush and the spreader cone 1 are matched to form a bent exhaust channel, so that gas can be conveniently exhausted, and the product quality is improved; the diffluence cone 1 comprises a cylindrical part 2 and a plurality of bosses 3, the bosses 3 are arranged above the cylindrical part 2, two opposite clamping grooves 10 are arranged below the cylindrical part 2, the clamping grooves 10 are convenient to install the diffluence cone 1, grooves 4 are arranged on the bosses 3, first grooves 5 are arranged on the cylindrical part 2, and the grooves 4 are matched with the first grooves 5 to form a channel; the groove 4 comprises a curved upper part and an inclined lower part, the radius of the curved surface of the upper part is gradually reduced from top to bottom, the curved upper part and the inclined lower part enable molten metal to flow more smoothly, so that the pressure loss is reduced, the defects of casting shrinkage, undercasting and the like are reduced, the casting quality is obviously improved, a bulge 6 is arranged in the middle of the channel, the upper end of the bulge 6 is curved and matched with the upper part of the groove 4, the middle of the bulge is inclined and matched with the lower part of the groove 4, the lower end of the bulge is trapezoidal, the molten metal can be divided into two strands by the bulge 6, the molten metal gap is compensated, the flow speed can be coordinated, and the solidified molten metal can be conveniently separated from the channel by the bulge 6 after the machining is finished, so that the service life of the; the first groove 5 is in a horn shape, the width of an opening of the first groove is gradually increased from inside to outside, and the outermost opening is in a smooth arc shape, so that the width of the opening is further increased, and the flow speed can be balanced; the two optimized bosses 3 are arranged on the upper part of the cylindrical part 2 in opposite directions by taking the central axis of the cylindrical part 2 as a symmetry line, and the outer parts of the two bosses 3 can be connected together, so that the difficulty of processing and manufacturing can be reduced.
