The manufacturing mode adopting the embedded type assembly structure has the advantages of low cost and high requirements on the burning-in assembly technology, and is difficult to process slightly and needs to be manufactured again. In addition, when the die casting mold is used for die casting production, the temperature of the aluminum liquid is up to 650 ℃, water leakage is easy to occur at the connection position between the combined cooling ring and the combined sprue bush main body in short use time, and the explosion phenomenon is easy to occur if a repair welding mode is adopted for the connection position of the sprue bush; therefore, due to water leakage, some sprue bush structures are not provided with cooling rings, but the water circulation of the cooling rings is not used for cooling, and the hammer heads can be worn at too high temperature during production.

(2) The water circulation channel formed by the five cooling water pipes is difficult to process and does not accord with the cost economic benefit. (3) The rubber sealing strip is needed to prevent water leakage, and the actual production is not feasible, because the melting point of the rubber is low, the melting point of aluminum is about 650 ℃, and even if the rubber sealing gasket is made of a high-temperature resistant material, the situation is also changed that the rubber cannot be used in the 650-DEG cast aluminum production, and the situation that water leakage occurs in sequence is avoided, so that the water leakage cannot be prevented by using the rubber sealing strip; the technical proposal of the patent is that the rubber sealing ring is melted in die casting from actual production, and the rubber sealing ring cannot be practically used.
Accordingly, there is a need for improvements in the art of sprue bush structures that ameliorate the above-described problems of the prior art.
