Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The embodiment of the utility model relates to a stepped frustum-shaped spreader cone structure, as shown in figures 1-3, comprising a first stepped spreader cone 1, a second stepped spreader cone 2 and a guide sleeve 3, wherein the first stepped spreader cone 1 is in a frustum cone structure, the front side of the front part is embedded with a second step spreader 2, the height of the second step spreader 2 is less than that of the first step spreader 1, the upper end of the first step spreader cone 1 is vertically provided with a guide sleeve 3, the front side of the guide sleeve 3 is provided with an outflow port 5, the upper end of the second step flow dividing cone 2 is provided with a flow dividing groove 7, the outflow port 5 of the guide sleeve 3 is communicated with the rear side of the flow dividing groove 7 through a flow passage 6, the front side of the splitter box 7 is symmetrically provided with two splitter openings 8, and the front side conical surface of the second step splitter cone 2 is provided with branch runner grooves 9 which are in one-to-one correspondence with the two splitter openings 8.
Two thimbles are vertically installed side by side about all in first step spreader 1 and the second step spreader 2.
The front end of the bottom surface of the outflow port 5 adopts a cambered surface structure with the front part bent downwards.
The lower end of the shunt opening 8 is lower than the bottom surface of the shunt groove 7, and the shunt opening 8 and the branch flow channel groove 9 are in arc surface transition.
And the lower end surfaces of the first step spreader cone 1 and the second step spreader cone 2 are provided with rectangular connecting blocks 4.
Examples
when aluminium liquid pours into, the egress opening 5 through the uide bushing 3 front side flows out, aluminium liquid enters into splitter box 7 along runner 6, splitter box 7 shunts aluminium liquid and flows out from reposition of redundant personnel opening 8 and enters into a runner groove 9, a runner groove 9 lower extreme is close to the product die cavity, flow channel node through on the lower die core enters into the product die cavity, because runner 6 and a runner groove 9 of first step diffluence awl 1 and second step diffluence awl 2 all adopt the inclined plane structure, can effectively improve aluminium liquid flow velocity, thereby improve the production efficiency of mould.
