Description

TECHNICAL FIELD The present invention relates to a device for casting a deformed pipe or a deformed pipe such as a manhole cover by using a vanishing model made of expanded polystyrene, and in particular, It is suitable for manufacturing large-scale molds with a length of 1 m or more in the moving line, and is a fully automated manufacturing line from molding to unraveling.

(Prior Art) There has been a method of manufacturing a cast iron product by casting using a vanishing model made of expanded polystyrene or the like. In this manufacturing method, the vanishing model is set in the casting frame, then the sand is filled into the casting frame (molding process), the casting frame is vibrated to make the sand dense, and the sand is placed inside and outside the vanishing model. Sufficiently spread it (vibration process), then vacuum the inside of the flask to reduce the pressure inside the frame and pour it into the frame to replace the disappeared model with molten metal (pouring process). After cooling, the flask is inverted to take out the cooled product, sand, etc. (frame breaking step).

(Problems to be Solved by the Invention) There is almost no conventional casting apparatus that uses the vanishing model so that all the above-mentioned production steps are lined up so that castings can be continuously cast. The product weight of brake master cylinders, manifolds, etc.
In the casting of small automobile parts up to 10 kg, only some of the steps except the above-mentioned modeling step and unraveling step are partially lined up. The flask used in this case is vertical and horizontal
It was about 90 cm in size.

The production process for large castings such as deformed pipes with product weights of about 10 to 50 kg is not even partly lined up, and it is common sense to carry out each process individually. The flask used in this case is about 1 m in length and width.

In order to line up the production process of large casting products, it is possible to enlarge the equipment of the small production line,
Then, only part of the casting process can be made into a line, and the effect of making a line is halved.

The place where sand is filled in the flask, the place where the flask is vibrated, the place where the pouring is done, etc. are individually and separately arranged at different places in the factory, and they are arranged without considering the order of the work process. Therefore, in order to move the casting flask in the order of the casting process, the casting flask had to be hung by a crane and moved between them. Therefore, the range of casting work is widened, work efficiency is poor, and there is a problem in work safety.

(Object of the Invention) An object of the present invention is to make all the processes from the molding process to the unraveling process into a series, and to make it possible to circulate a plurality of casting frames intermittently and continuously on the line, and thereby the manufacturing line. To provide a manufacturing device in a vanishing model that is fully automated, is small in size, does not take up space, is easy to work, has good work efficiency, is safe in terms of work, and can efficiently manufacture high-precision cast iron products.
