It adopts split type structure, and the taper point portion that often contacts with aluminium liquid can be changed to save manufacturing cost, it also has the feeding function when cooling the shaping to the mould.
Description
Technical Field
The utility model relates to the technical field of casting, in particular to a sprue spreader for a casting machine.
Background
The sprue spreader used on the existing low-pressure casting machine is an entity formed by one-time molding, and has the following defects: 1. the filter screen is pressed to the flow cone during casting, and aluminium liquid in the holding furnace enters into the casting mould through the stalk, is provided with the flow cone at the liquid inlet of the casting mould, and when opening pressure, aluminium liquid flows into the casting mould, and when closing pressure, aluminium liquid stops flowing into the casting mould from the stalk. Therefore, the lower part of the shunting cone, particularly the cone tip part can be contacted with high-temperature aluminum liquid for a long time, and the lower part of the shunting cone is easy to corrode and damage, so that the shunting cone can be replaced after a period of time, the using amount of the shunting cone is large, and the production cost is increased. 2. When molten aluminum is cooled and formed in a casting mold, the existing sprue spreader does not have the function of feeding the mold.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a split-type sprue spreader for casting, which adopts a split-type structure, and the part of a cone tip which is frequently contacted with molten aluminum can be replaced, thereby saving the production cost and having the feeding function when a mold is cooled and formed.
The technical solution of the utility model is as follows:
the split-type sprue spreader for casting comprises a sprue spreader main body and a cone tip, wherein the cone tip is screwed and fixed at the lower part of the sprue spreader main body, the cone tip is formed by forming a cone tip connecting column on the upper surface of a cone tip part of the cone tip part, and the cone tip connecting column and the cone tip part have the same axial lead;
a shunting cone recess is formed in the lower portion of the shunting cone main body, the cross section of the shunting cone recess is T-shaped, a cone tip connecting column is fixed in the shunting cone recess in a threaded mode, and the upper surface of a cone tip portion is contained in the shunting cone recess.
And a feeding groove is formed on the outer diameter surface of the sprue spreader main body.
And a main screw hole and an auxiliary screw hole are formed in the main body of the tap cone.
The main screw hole and the cone tip have the same axis.
The number of the auxiliary screw holes is not less than three.
The utility model has the beneficial effects that:
it adopts split type structure, and the taper point portion that often contacts with aluminium liquid can be changed to save manufacturing cost, it also has the feeding function when cooling the shaping to the mould.
Drawings
FIG. 1 is a cross-sectional view of the present invention;
fig. 2 is an exploded view of the present invention.
In the figure: 1. a conical tip; 2. a spreader cone main body; 3. a feeding groove.
Detailed Description
Example (b): as shown in fig. 1 and 2, the split-type sprue spreader for casting comprises a sprue spreader main body 2 and a cone tip 1, wherein the cone tip 1 is screwed and fixed at the lower part of the sprue spreader main body 2, the cone tip 1 is formed by forming a cone tip connecting column 1b on the upper surface 1c of the cone tip part 1a, and the cone tip connecting column 1b and the cone tip part 1a have the same axial lead;
a shunting cone recess 2a is formed in the lower portion of the shunting cone main body 2, the cross section of the shunting cone recess 2a is T-shaped, a cone tip connecting column 1b is fixed in the shunting cone recess 2a in a threaded mode, and the upper surface 1c of a cone tip portion is contained in the shunting cone recess 2 a.
And a feeding groove 3 is formed on the outer diameter surface of the sprue spreader main body 2.
The main tap hole 22 and the auxiliary tap hole 21 are formed on the tap body 2.
The main screw hole 22 and the cone tip 1 have the same axis.
The number of the auxiliary screw holes 21 is not less than three.
The working principle is as follows: the splitter cone in the prior art is integrally formed and originally has a main screw hole 22 and an auxiliary screw hole 21, and the cone tip part is easy to corrode and damage after the splitter cone is used for a period of time, so that the splitter cone needs to be replaced frequently, and the production cost is increased.
After the split-type structure is adopted, only the cone tip 1 needs to be replaced, so that the use cost of the spreader cone can be saved, and the production cost is reduced. When pressure is opened, aluminium liquid flows into the mould from the external diameter face of reposition of redundant personnel awl in, when pressure is closed, has a small amount of aluminium liquid to remain in feeding groove 3, and feeding groove 3 only communicates with each other with the mould when reposition of redundant personnel awl is closed, like this when the aluminium liquid cooling in the mould, the aluminium liquid in feeding groove 3 can have the feeding effect to the aluminium liquid in the mould to improve the quality of the product of production.
