Abstract
The utility model discloses a hot core box die assembly, comprising die bodies, corresponding top core rods and top core plates. The die bodies include a moving die body and a stationary die body. The die bodies are both provided with a heating hole and parallel lead holes. One end of each top core rod is arranged in the lead hole of the corresponding die body and can slide relative to the die body, and the other end of the top core rod is fixed on the top core plate. The die assembly further comprises heat preservation plates and steel plates. Each heat preservation plate is bonded and fixed on a corresponding outer surface of the corresponding die body and is provided with functional through holes corresponding to the heating hole and the lead hole of the die body. Each steel plate is arranged at the outer surface of the corresponding heat preservation plate and is provided with functional through holes corresponding to the functional through holes on the heat preservation plate. The steel plates on the same die body are connected into a whole body to form a steel cover which is fixedly connected with the corresponding die body. The die assembly is high in energy utilization ratio when in use, and the sand mold and the sand core are good in quality.
Description
Technical field
The utility model relates to a kind of parts of hot box.
Background technology
Sand mold and core are essential in casting, and sand mold and core are often made by hot box.The die body assembly of hot box has dynamic model body, cover half body, plunger tip bar and plunger tip plate.The used material of die body is generally ironcasting or forging, is respectively equipped with the guide hole and the bottoming hole that connect die body on each die body, and guide hole wherein is parallel to each other and ecto-entad communicates with the inner chamber of die body, and bottoming hole does not then communicate with inner chamber.One end of plunger tip bar is fixedlyed connected with the plunger tip plate, and the other end is arranged in the guide hole of die body and can moves with respect to die body.After dynamic model body and cover half body lump together, synthetic die cavity of the inner chamber of two die bodys and the core shooting mouth (two die bodys that lump together can be called the matched moulds body) that communicates with die cavity.At this moment, the molding sand that can adopt core shooter will be mixed with binding agent is injected in the die cavity by the core shooting mouth of matched moulds body, and the feeding thermal current impels the adhesive cures in the molding sand and molding sand is bonded together securely in the bottoming hole of each die body then.But, when the feeding thermal current heats, because six of the appearance of matched moulds body (are meant for each die body and do not comprise that inner chamber one side is at 5 interior outer surfaces, these 5 outer surfaces can be referred to as the outer surface of die body) all be exposed in the air, can cause a large amount of losses of heat and cause inhomogeneous to the heating of the die body of hot box, not only reduce the effective rate of utilization of electric energy or fuel gas calorie, can't guarantee the quality of sand mold or core.
The utility model content
The quality of higher and sand mold and core of the energy utilization rate die body assembly of hot box preferably when the purpose of this utility model is a kind of the use is provided.
The technical scheme that realizes the utility model purpose is: a kind of die body assembly of hot box, comprise die body and corresponding plunger tip bar and plunger tip plate, and die body is dynamic model body and cover half body; The guide hole that each die body has bottoming hole and is parallel to each other; One end of each plunger tip bar is arranged in the guide hole of die body and can slides with respect to die body, and the other end of each plunger tip bar is fixed on the plunger tip plate; Also comprise warming plate and steel plate, each adhering heat insulating plate is fixed on the corresponding outer surface of a corresponding die body, and is provided with the function corresponding through hole at bottoming hole and guide hole place with die body; Each steel plate is arranged on the outer surface of a corresponding warming plate, and also is provided with the function corresponding through hole in each function through hole of warming plate; Be positioned at adjacent steel plate on the same die body and be fixed together and become a steel case, this steel case is fixedlyed connected with corresponding die body.
Be fixedly connected as welding between the above-mentioned adjacent steel plate, the welding that is fixedly connected as of steel case and corresponding die body.
The utlity model has positive effect: (1) die body assembly of the present utility model in use, the die body surface ratio does not have the temperature on die body surface of the hot box of covering insulation material to reduce more than 50 ℃, reduced hot box thermal loss in the course of the work effectively, improve rate of energy, improved the environment of core shooting operation.(2) because heat is kept in die body preferably, make the heating degree of the molding sand that is positioned at the die cavity center basic identical with the heating degree of the molding sand that is positioned at die cavity edge, and make die cavity binding agent everywhere be subjected to the speed of heat cure basic identical, thereby make the quality of the sand mold that finally obtains or core better.
Description of drawings
Fig. 1 is the structural representation of the die body assembly of hot box of the present utility model.
The specific embodiment
The die body assembly of hot box of the present utility model comprises die body 1 and corresponding plunger tip bar 2 and plunger tip plate 3, also comprises warming plate 6 and steel plate 7.
Die body 1 is dynamic model body and cover half body, has core shooting mouth 5 between dynamic model body and the cover half body, the guide hole that each die body 1 has bottoming hole 4 and is parallel to each other.One end of each plunger tip bar 2 is arranged in the guide hole of die body 1 and can slides with respect to die body 1, and the other end of each plunger tip bar 2 is fixed on the plunger tip plate 3.Each warming plate 6 is bonded and fixed on the corresponding outer surface of a corresponding die body 1, and is provided with the function corresponding through hole at bottoming hole and guide hole place with die body 1, and warming plate adopts insulation material to make, and core shooting mouth 5 places do not have insulation material.Each steel plate 7 is arranged on the outer surface of a corresponding warming plate 6, and also is provided with the function corresponding through hole in each function through hole of warming plate.Be positioned at adjacent steel plate 7 on the same die body 1 and be weldingly fixed on and become a steel case together, this steel case is fixing with corresponding die body 1 welding.
The die body assembly of hot box of the present utility model can stop the thermal loss of hot box die body outer surface, reduce hot box correlation core equipment and hot box coupling part and, the thermal-radiating influence of closing piston seal.Adopt the programming rate of the hot box of die body assembly of the present utility model obviously to improve, the temperature on hot box surface obviously reduces, the hot box surface ratio of covering and heat insulating plate does not have the temperature on the hot box surface of covering and heat insulating plate to reduce more than 50 ℃ after testing, reduced hot box thermal loss in the course of the work effectively, improve rate of energy, improved the environment of core shooting operation.
