Description
Technical field
A kind of the present invention relates to low pressure technical field of mold, more particularly to die casting spreader.
Background technology
Typically using the monolithic construction made by H13 steel, spreader is aluminium liquid note to existing die casting spreader
The region for being contacted after entering in mould first, aluminium liquid are imported in mold cavity through spreader drain.In press casting procedure, spreader
By high temperature aluminium liquid bump, corrosion is fast, needs to carry out repair welding and amendment to spreader when reusing；In addition spreader is such as
Fruit repair welding corrects not in place, then can have a strong impact on the quality of foundry goods.
The content of the invention
It is an object of the invention to provide a kind of die casting spreader, to extend the service life of spreader, improves
The quality of production of foundry goods.
It is that, up to this purpose, the present invention is employed the following technical solutions：
A kind of die casting spreader, leads to including shunting cone and shunting conehead, the shunting cone and shunting conehead
Cross screw thread to be connected；The shunting cone is stair-stepping column structure, including the first cone segments, the second cone segments and the 3rd
Cone segments, are provided with external screw thread in the Three-cone section；The shunting conehead includes conehead platform and conehead, the conehead platform
The screwed hole being adapted with the external screw thread in Three-cone section is provided with axially；The shunting cone passes through third hand tap with shunting conehead
Body section is connected with screwed hole.
Further, the shunting conehead is made up of wolfram steel, and the shunting cone is made up of H13 steel, improves spreader
Service life.
Further, the diameter with diameter greater than the second cone segments of first cone segments, the diameter of the second cone segments are big
In the diameter of Three-cone section, the axially position of spreader is carried out by the lower surface of the first cone segments of reference cone head body.
Further, the end face near the first cone segments of second cone segments and near the first cone segments second
One end of cone segments opens up fluted respectively.
Further, the diameter with diameter greater than the second cone segments of the conehead platform, is realized by the upper surface of conehead platform
The axially position of spreader and clamping.
Beneficial effects of the present invention：Spreader of the present invention is using the split being made up of shunting cone and shunting conehead
Formula structure design, shunting conehead are made using wolfram steel material, improve the service life of spreader, only need more when changing spreader
Shunting conehead is changed, simple structure changes convenient；The tapered segment of spreader is used as shunting conehead overall processing, it is to avoid point
Flow cone head merotomizes processing, to ensure the round and smooth degree of the tapered segment of spreader, and enhances the intensity of shunting conehead.

Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
A kind of die casting spreader as shown in Figures 1 to 3, including shunting cone 2 and shunting conehead 1, the shunting
Conehead 1 is made up of wolfram steel, and shunting cone 1 is made up of H13 steel, improves the service life of spreader；The shunting cone 2 is rank
The column structure of scalariform, including the first cone segments 21, the second cone segments 22 and Three-cone section 23, in the Three-cone section 23
It is provided with external screw thread 231；The shunting conehead 1 includes conehead platform 11 and conehead 12, and the axial direction of the conehead platform 11 is provided with and the
The screwed hole 112 that external screw thread 231 in Three-cone section 23 is adapted；The shunting cone 2 passes through Three-cone with shunting conehead 1
Section 23 is connected with screwed hole 112.
The diameter with diameter greater than the second cone segments 22 of first cone segments 21, the second cone segments 22 with diameter greater than
The diameter of Three-cone section 23, carries out the axially position of spreader by the first locating surface 211 of the first cone segments 21.
The one of second locating surface 211 of first cone segments 21 and the second cone segments 11 near the first cone segments 21
End opens up fluted 221 respectively.
The diameter with diameter greater than the second cone segments 22 of the conehead platform 11, by the first locating surface 111 of conehead platform 11
Realize axially position and the clamping of spreader.
The present embodiment is adopted using the split-type structural design being made up of shunting cone 2 and shunting conehead 1, shunting conehead 1
Wolfram steel material is made, and improves the service life of spreader, need to only change shunting conehead, structure letter when changing spreader
It is single, change convenient；The tapered segment of spreader is used as shunting conehead overall processing, it is to avoid a shunting conehead is merotomized plus
Work, to ensure the round and smooth degree of the tapered segment of spreader, and enhances the intensity of shunting conehead；By 211 He of the first locating surface
Second locating surface 111 realizes axially position and the clamping of spreader.
Obviously, the above embodiment of the present invention illustrates example of the present invention just for the sake of clear, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
