The sprue spreader adopts a split structure comprising the sprue spreader body and the sprue spreader head, the sprue spreader head is made of a tungsten steel material, the service life of the sprue spreader is prolonged, all that is needed is to replace the sprue spreader head when the sprue spreader needs to be replaced, the structure is simple, and the replacement is convenient.
Description
Technical field
The present invention relates to low pressure technical field of mold, particularly relate to a kind of die casting spreader.
Background technology
Existing die casting spreader generally adopts the monolithic construction made by H13 steel, and spreader is that aluminium liquid injects the region first contacted after in mould, and aluminium liquid imports in mold cavity through spreader drainage.In press casting procedure, spreader is by the bump of high temperature aluminum liquid, and corrosion is fast, needs to carry out repair welding and correction to spreader when reusing; If spreader repair welding or revise not in place in addition, then can have a strong impact on the quality of foundry goods.
Summary of the invention
The object of the present invention is to provide a kind of die casting spreader, to extend the service life of spreader, improve the quality of production of foundry goods.
For reaching this object, the present invention by the following technical solutions:
A kind of die casting spreader, comprise shunting cone and shunting conehead, described shunting cone is connected by threaded engagement with shunting conehead; Described shunting cone is stair-stepping column structure, comprises the first cone segments, the second cone segments and Three-cone section, described Three-cone section is provided with external screw thread; Described shunting conehead comprises conehead platform and conehead, and the axis of described conehead platform has the screwed hole suitable with the external screw thread in Three-cone section; Described shunting cone is connected by Three-cone section and screwed hole with shunting conehead.
Further, described shunting conehead is made up of wolfram steel, and described shunting cone is made up of H13 steel, improves the service life of spreader.
Further, the diameter of described first cone segments is greater than the diameter of the second cone segments, and the diameter of the second cone segments is greater than the diameter of Three-cone section, is carried out the axial location of spreader by the lower surface of the first cone segments of point conehead body.
Further, groove is offered respectively near one end of the end face of the first cone segments of described second cone segments and the second cone segments of close first cone segments.
Further, the diameter of described conehead platform is greater than the diameter of the second cone segments, is realized axial location and the clamping of spreader by the upper surface of conehead platform.
Beneficial effect of the present invention: spreader of the present invention adopts the split-type structural become with spreader head group by shunting cone to design, shunting conehead adopts wolfram steel material to make, and improves the service life of spreader, only need change shunting conehead when changing spreader, structure is simple, and it is convenient to change; The tapered segment of spreader, as shunting conehead overall processing, avoids and a shunting conehead is merotomized processing, to ensure the round and smooth degree of the tapered segment of spreader, and enhance the intensity shunting conehead.
