Description

The present invention relates to cooling of a V-pro pouring frame.
Conventionally, there has been no device for cooling the V-pro pouring frame. The temperature rise of the frame is suppressed by vacuum suction after pouring.
However, the vacuum suction is stopped for a certain time, and there is a process of cooling in the natural frame until the frame is released. At this time, when casting a product with a large heat capacity such as a counterweight, the heat from the cast product The temperature of the frame and the surface plate rose, and there was a problem that the film used was welded to the metal frame and the surface plate.
JP 2002-45959 A
An object of this invention is to suppress the temperature rise of the pouring frame of V pro and to prevent film welding.
In order to achieve the above object, a pouring frame cooling device according to the present invention is characterized in that compressed air is blown onto the side surface and the lower surface of a pouring frame of a V professional to cool it.
By blowing compressed air into a chamber whose side is in contact with the metal frame and the film and cooling it by air, it is possible to suppress the temperature rise of the metal frame and to prevent the film from being welded.
Further, by blowing compressed air to the bottom surface of the surface plate and air cooling, it is possible to suppress the temperature rise of the surface plate and prevent the film from being welded.
A pouring frame cooling device to which the present invention is applied will be described in detail with reference to the drawings. As shown in FIG. 3, the conventional V pro metal frame has a chamber (hollow) shape 11 on both the upper and lower frames to maintain the mold, and the chamber is formed by suction from a vacuum pump (not shown). 11 The inside is evacuated and the sand mold 10 is formed by negative pressure. The sand mold 10 is surrounded by the upper frame 3, the lower frame 4, the upper surface film 7, the product surface films 8 and 8, and the lower surface film 9, and is sucked to maintain a shape.
During pouring, the part of the product surface film 8, 8 that comes into contact with the cast product 6 is burned away, but the part sandwiched between the upper frame 3 and the lower frame 4 remains in the form of a film and is removed when the frame is released. The Further, the upper film 7 and the lower film 9 are removed in the form of a film before unpacking.
After pouring, when the cast product 6 cools and hardens to some extent, the vacuum suction is stopped and the product is naturally cooled in the frame. At this time, when casting a product with a large heat capacity such as a counterweight, the heat of the cast product 6 It is transmitted to the upper frame 3, the lower frame 4, and the surface plate 5 through the sand mold 10, and the portion of the product surface film 8 that is sandwiched between the upper frame 3 and the lower frame 4 and the lower surface film 9 is a metal frame or There was a case where a problem of welding to the surface plate occurred (Fig. 3).
Therefore, the nozzles 1 and 1 for the side of the metal frame and the nozzle 2 for the bottom of the surface plate are installed, and compressed air is blown and cooled.
For air blow from the side, air cooling chambers 12 and 12 are provided on the parting surface (surface where the upper and lower frames are combined), the removable side nozzles 1 and 1 are inserted, and blow is turned on with the manual valve 14. -A structure that operates the switch off (Figs. 1 and 2).
Regarding the air blow on the bottom surface, the bottom nozzle 2 is installed near the lower center of the surface plate 5 and the blow valve is turned on and off with the manual valve 13 (FIGS. 1 and 2).
The air cooling chambers 12 and 12 are provided with several holes, which serve as insertion ports for the side nozzles 1 and air inlets and outlets (FIG. 1).
(Process)
The metal frame is vacuumed for a certain period of time after casting (to maintain the sand mold). After that, the suction is stopped and naturally cooled in the frame. At this time, compressed air is blown to actively cool the air.
This invention is a semi-automated facility, so it is configured to manually attach and detach nozzles and manual valves. However, using an actuator such as an air cylinder, it is possible to automate nozzle attachment and detachment, and to automate air blow using solenoid valves. It is.
It is a plane sectional view (sectional view of a chamber part) of one example of the present invention. FIG. 2 is a front sectional view of FIG. It is front sectional drawing of the conventional structure.
