Description

The present invention relates to lantern-style iron castings, and more particularly to lantern bells made of thin-walled and lightweight castings, which are used for bells or light-removing purposes.

Conventionally, sand casting is performed using a sand mold made of cast sand, and the molten metal injected into the sand mold solidifies into a casting (see, for example, Patent Document 1). In such conventional sand casting, in a casting method called manual casting (self-hardening), molding is performed using a wooden mold, a resin mold, a master (main mold) of a mold, and a core mold as needed. When removing the master (main mold) or core mold from the sand mold (cutting mold), it is necessary to add a draft (tilt angle).

In recent years, the existence of cast products has tended to diminish in daily life, but iron castings are originally obtained from plastic products, aluminum products, etc. in terms of the taste, texture, texture, tone when hit, etc. of the cast surface. It has a unique value that cannot be found. In addition, it is durable, long-lasting (durable), and has a high reuse rate, which makes it suitable as daily necessities or daily necessities. The possibility of application is high.

Conventionally, cast iron products are generally limited to a thin wall shape of 5 mm from the viewpoint of manufacturing the main mold and core mold shapes described above, but when the cast iron products are moved or carried around, the limit is generally set to 5 mm. Further maximum weight reduction is required. In addition, it is necessary to develop and design an appropriate value for the thickness and thickness of the skeleton (the path through which the hot water flows) through which the molten metal passes to the end of the product by changing the thickness of a part of the skeleton of the cast iron product. Furthermore, it is necessary to develop a highly accurate main mold that can be suppressed with the minimum deburring process without damaging the casting surface. However, in the conventional cast iron products or manufacturing techniques thereof, the present situation is that few proposals have been made to provide a solution to these problems by paying attention to these problems.
