Description
Technical Field
This technical scheme belongs to the foundry art field, specifically is a platform is collected to casting waste gas of wheel hub foundry goods.
Background
In the prior art, a crankshaft damper (also called a torsional damper) is an important component of an internal combustion engine such as an automobile engine. In order to reduce torsional vibration of a crankshaft, a torsional vibration damper is often installed at the front end of the crankshaft where the torsional vibration amplitude is the largest in an automobile engine at present. A typical crankshaft damper is constructed from a hub, rubber, and inertia ring connection. The hub is used to connect the entire damper to the crankshaft. The hub has small volume and relatively low structural strength, and parts are obtained by casting and lathe machining. Because the hub is small, from the perspective of improving efficiency, saving cost when casting, adopt many of a type to make mould and sand mould more. The casting is small, the pressure of molten iron in the cavity to the outside is not large, a flaskless molding mode can be adopted, and the solidified resin sand mold is molded to pour the molten iron.
According to the manufacturing characteristics of the molding machine, a plurality of (n) same sand molds are manufactured, and are sequentially combined to form a plurality of (n-1) cavities, and then molten iron is sequentially injected into the cavities one by one. The operation mode has the characteristics of small occupied space and need of personnel to pour molten iron from the outer pouring gate one by one. When the molten iron is poured, the gas discharged from the sand mould is ignited at the position of a dead head and/or a gas outlet, and the functions of the gas are mainly as follows: 1. the defective products caused by unsmooth exhaust are prevented, open fire is used for igniting the periphery of the sand mold to help exhaust gas, and the gas in the cavity is fully exhausted; 2. the gas generated by high-temperature gasification of the binder, moisture and the like of the sand mold is directly ignited to reduce the pollution of waste gas. Although non-toxic products are forced to be used with the development of binder technology, waste heat generated by the combustion of exhaust gas is still an important pollution source of thermal pollution in this mode of operation.

Furthermore, the iron plate forming the top surface of the closed box body is also connected with a reinforcing rib; the strengthening rib includes horizontal muscle and the muscle of indulging of many mutually perpendicular connections, and iron plate connects the top surface at the strengthening rib.
Furthermore, the outlets of the sprue cup and the riser cup are connected with extension pipes, and the shapes of the extension pipes correspond to the shapes of an outer sprue of the sand mold and the riser.
Further, asbestos cloth is connected between the sprue cup and the sprue cup through hole and between the riser cup and the riser cup through hole; the asbestos cloth covers the sprue cup through hole and the riser cup through hole, and holes corresponding to the sprue cup and the riser cup in shape are formed in the asbestos cloth.
The sprue cup and the riser cup are arranged on the corresponding sprue cup through hole and the riser cup through hole after penetrating through the holes. The asbestos cloth can be connected with the iron plate on the top of the box. Because the asbestos cloth has certain twisting ductility, the holes on the asbestos cloth can be attached to the pouring cup and the riser cup, and the holes can be slightly split. And the texture of asbestos cloth is similar to canvas, and the asbestos cloth has a radial supporting effect on the sprue cup and the riser cup. When the pouring cup through hole or the riser cup through hole is not used, the pouring cup through hole or the riser cup through hole is pressed by an iron plate or a rotating block on the asbestos cloth.
Furthermore, a sliding table corresponding to the tray is connected to the bottom surface in the closed box body.
The structure of the sliding table can be that a plurality of parallel I-shaped steels are distributed on the bottom surface in the closed box body, and a plurality of rollers are respectively connected between adjacent I-shaped steels through bearing structures. Meanwhile, a stop block for blocking the tray is connected to the tail end (the end far away from the feeding door) of the I-shaped steel. A tray filled with sand molds is fed into the closed box body from the opening of the feeding door by a forklift, is placed on the roller, is pushed into the box body, is blocked by the stop block, and is closed.
Furthermore, circulating water pipes are connected to the three inner side walls of the closed box body. The circulating water pipe can be designed into an S shape, and the outer wall of the water pipe can be welded with radiating fins. Except that opening a door a lateral wall, 3 inside walls all connect circulating pipe, take away concentrated collection heat transfer processing to molten iron cooling heat dissipation.
By adopting the platform, the waste gas generated in the pouring process can be collected and treated in a centralized manner, a standing platform is provided for pouring operators, and the waste heat generated in the casting cooling process can be collected and treated in a centralized manner.
