JPS6037255A - Treating device for inside surface at one end of centrifugal casting mold - Google Patents

Abstract

PURPOSE:To perform a treatment for an inside surface in the same place as places for pouring, drawing, etc. by providing a treating device body in the position deviated from the axial center of a casting mold and disposing turnably and movably back and forth the respective treating devices to a frame which moves to and from the position where the frame faces the opening of the casting mold. CONSTITUTION:A body slide frame 8 which can be moved to and from a position 12 where said frame faces the opening at one end 2 of a casting mold 1 is provided to the body 5 of a treating device 4 disposed in the position deviated from the axial center near the end 2. A swiveling frame 15 which can swivel between the position 17 along the frame 8 and the position 18 along the axial center of the mold 1 is mounted to the top end of the frame 8. An end slide frame 20 which can move back and forth from the frame 15 toward the inside of the end 2 is further provided. A brushing device and a spray device for mold coating for the inside surface of the mold 1 are attached to the frame 20. The treatment for the inside surface of the casting mold and the treatment such as pouring, drawing, etc. are thus accomplished in the same place, by which the space over the entire part of the installation is decreased.

Description

[Detailed description of the invention] The present invention relates to an apparatus for treating the inner surface of one end of a centrifugal casting mold.

For example, when centrifugally casting a cast iron pipe with a socket, the inner surface of one end of the centrifugal casting mold often has a special shape. Therefore, in order to deal with this, it is necessary to perform special treatments such as auxiliary cleaning and auxiliary coating on the inner surface of this one end. For this reason, conventionally, when applying internal surface treatment to the socket of a centrifugal casting mold for cast iron pipes, a fixed internal surface treatment device installed opposite the opening of the mold or a movable device that can move along the axial direction of the mold has been used. A linear inner surface treatment device is used. By the way, in general, centrifugal casting equipment requires a space for drawing out the cast product in the axial direction of the mold, and especially in centrifugal casting equipment for cast iron pipes, it is necessary to provide a front cover attachment/detachment device near the opening on the socket side of the mold. However, there is a problem in that the extraction space and the front cover attachment/detachment device spatially interfere with the inner surface treatment device. Conventionally, the inner surface treatment and the pouring and drawing of the metal had to be carried out at different locations, and the mold as a casting mold had to be moved between these locations. Furthermore, since the inner surface treatment and pouring/drawing are performed in separate locations, there is also the problem that the overall space of the casting equipment becomes large.

Therefore, the present invention makes it possible to perform inner surface treatment and other processes such as pouring and drawing using devices in the axial direction of the mold in the same place, eliminating the need to move the mold and reducing the overall space of the casting equipment. The purpose is to enable installation.

In order to achieve this object, the present invention provides a processing device main body at a position off the axis of the centrifugal casting mold near one end of the mold, and a processing device main body located at a position opposite to the opening at one end of the mold from the processing device main body. A main body slide frame that can move in and out toward the mold is provided, and a rotating frame that can pivot between a position along the main body slide frame and a position along the axis of the mold is provided on the main body slide frame, A tip slide frame is provided that can move in and out from the rotating frame toward one end of the mold, and the tip slide frame is provided with a mold inner surface brushing device and a coating mold spray device.

Therefore, if there is a location near one end of the mold that is off the axis of the mold, the inner surface treatment device can be installed even if there is something that interferes with the axis of the mold, such as a pull-out space or a front cover attachment/detachment device. Not only can the inner surface treatment and other treatments using equipment in the axial direction of the mold, such as pouring and drawing, be performed in the same place, but there is no need to move the mold, and the entire casting equipment can be installed in a small space.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figures 1 and 2, (1) is a mold for centrifugal casting tubes, which is arranged horizontally and has one end (

When brushing is finished, operate the cylinder device () to lift the rotating brush (c), and while gradually moving the tip slide frame () in the direction of removing it from the mold (1), move the mold spray device (a). Coating agent α1
Inject. On the way, the tip slide frame (E) is the fourth
Once the position shown in the figure is reached, the movement of the tip slide frame (E) is temporarily stopped, and the mold coating agent is sprayed intensively onto the socket rounded part θη and the back of the collar (6). After that, the tip slide frame (E) is further moved to complete the mold coating work.

As the inner surface processing is completed as described above, the tip slide frame (E) is stored in the swing frame 00, the swing frame OQ is returned to the position 071 along the main body slide frame, and the main body slide frame Q ) pull up. As a result, the vicinity of the opening of one end (2) of the mold (1) is opened, so a front lid attachment/detachment device (not shown) is brought close to the one end (2), the front lid is attached, and the molten metal is poured into the tube. to be cast. At this time, if a cover (B) is attached to the tip of the main body slide frame 0η as shown in FIG. 1, damage to the apparatus due to molten metal scattering can be prevented.

As described above, according to the present invention, if there is a location off the axis of the mold near one end of the mold,
Even if there is something that interferes with the axial direction of the mold, such as a drawing space or a front cover attachment/detaching device, the inner surface treatment device can be installed, and the inner surface treatment is the same as other processing using devices in the axial direction of the mold, such as pouring and drawing. Not only can casting be carried out in a small location, but it also eliminates the need to move the mold, allowing the entire casting equipment to be installed in a small space.
