Abstract
The utility model belongs to an auxiliary part for casting, in particular to a runner cup for lost foam casing, which has the advantages of simple operation and repeated use during usage. The runner cup comprises a heat-resistant iron body and a coating layer attached on the surface in the cavity of a body cup; the outlet of the cavity bottom of the body cavity is provided with an inner stepped hole; and the inner diameter of the inner stepped hole is the same as the diameter of the convex part of the top end of the downsprue of the lost foam. When the runner cup is used, the inner stepped hole arranged at the bottom of the runner cup is inserted into the downsprue of the lost foam.
Description
Technical field
The utility model belongs to casting accessory, particularly a kind of dispellable mould casting cup.
Background technology
Cup is one of important composition parts in metal casting technique, it is to be used for the passage that guide wire liquid enters die cavity, if the structure of cup and arrangement are unreasonable, just may make foundry goods produce defectives such as pore, slag blister, burning into sand, therefore correctly select structure, material and the size of cup and on foundry goods, reasonably settle extremely important.
The disappearance die casting is a kind of advanced person's a casting technique, at present, the dispellable mould casting cup generally adopts ceramic material or hard paste material to form through mechanical pressing, high-temperature roasting, and it has a body, is coated with the casting refractory coating on the cup inner cavity surface of body.The port of export of this cup is a straight channel, and the problem that the suction function that vacuumizes when preventing to pour into a mould makes molding sand enter running channel must use sand cover and mud bar to seal, and its complex operation, workload are big, and quality also is difficult to obtain assurance.In addition, existing cup is disposable use, and high material consumption causes a large amount of industrial refuses, and environmental pollution is more serious.
Summary of the invention
Problem to be solved in the utility model is improved existing cup, simple to operate and reusable dispellable mould casting cup when a kind of use is provided.
The technical scheme that addresses the above problem is: the dispellable mould casting cup that is provided comprises body and attached to the coat on the body cup inner cavity surface, improvements of the present utility model are that body adopts heat-resisting cast iron, there is an interior stepped hole in the exit of bottom, body cup chamber, and internal diameter of stepped hole is consistent with the diameter of disappearance mould sprue top protuberance in this.Only the interior stepped hole of cup bottom need be inserted on the disappearance mould sprue that coats coating during use and get final product.
Extraction after the cast for convenience is provided with the hole that handle is installed in cup body side, and screwed hole can be adopted in the hole of aforementioned generally speaking installation handle.
Compare with existing cup, the utility model can be reused hundreds of times, and not only cost reduces greatly, and can recycle, and has reduced the pollution to environment.Owing to be provided with an interior step with sprue is connected in cup bottom, needn't re-use that traditional dry sand overlaps and the mud bar seals, thereby simple to operate, reduced also that molding sand enters sprue and the situation that forms the burning into sand defective.In addition, weight of the present utility model is big, can overcome molten iron buoyancy, guarantees molten steel quality.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
As shown in Figure 1: cup body 1 adopts existing heat-resisting cast iron to make, and the molten bath, upper end in its glass chamber 2 is a hemispherical, with the interchannel of lower end be the arc surface transition all so that slow down the impact of molten iron.Respectively be provided with a threaded hole 3 in the both sides of body 1, bolt screws in threaded hole 3, the reinforcing bar handle is welded on the bolt, so that withdraw cup after the cast again.The outlet at bottom end of body 1 is provided with interior stepped hole 4, and it is a matched in clearance with the sprue that coats the disappearance mould of coating, and the height of interior stepped hole 4 is generally 12～20mm.Brush one deck casting fireproof coating before using earlier, oven dry then repeats above the operation twice.Each cast finishes and should withdraw cup immediately, while hot it is cleared up, and waits to cool to and mends fireproof coating of brush about 100 ℃ again, utilizes after cup self the waste heat drying promptly reusable.
