Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching frame facility in which only a sand casting mold is extracted from a casting flask containing a sand casting mold that has been poured into a casting mold to separate the casting mold and the sand casting mold from each other. The present invention relates to a flask leveling device that is raised and fixed.

[0002]

2. Description of the Related Art Conventionally, when performing a variety of operations such as framing, dies, and mold matching by elevating a casting frame with a built-in sand mold to a certain height level, as disclosed in JP-A-4-224045. A method is adopted in which the four corners of the flask are pushed up while being synchronized by the cylinder.

[0003]

In the leveling of the casting frame as described above, four cylinders are arranged below the casting frame and the cylinders are used to push up the casting frame. Since the equipment is in a place where the air pollution is severe, it is covered with dust hood and it is very difficult to perform maintenance and inspection. In addition, since many cylinders are used, there is a problem that troubles in the piping and wiring frequently occur. The present invention has been made in view of the above problems,
It is an object of the present invention to provide a casting frame leveling device in a punching facility in which the leveling of the casting frame can be accurately performed with a minimum of cylinders and the trouble of piping and wiring is reduced.

[0004]

In order to achieve the above-mentioned object, a casting flask leveling device in a punching equipment of the present invention comprises:
A stopper body for limiting the rise of the casting frame is provided above the transportation line of the casting frame, and a tubular guide tube is provided continuously to the upper portion of the stopper body, and a large number of it is provided on the surface below the transportation line of the casting frame. In a punching frame equipment in which a punch-out head attached with a sand removing piece is arranged, two pairs of bearings are provided in front of and behind two sets below the carrier line of the casting frame with a space wider than the lateral width of the casting frame. The rotary shafts are fixedly arranged at intervals, the rotary shafts are supported by the pair of two bearings, and rotary rotary members are erected via brackets at positions corresponding to the four corners of the casting frame of the rotary shafts. A rotary roller body that is rotated up and down from the lower side of the transfer line is attached to the rotary support body, a link mechanism is connected to both ends of the rotary shaft, and a horizontal cylinder is provided above one end of the rotary shaft. Place and pierce the lateral cylinder Characterized by being rotatably connected through the medium link and Nroddo one end of the rotary shaft.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of the frame equipment, and FIG. 2 is a view on arrow AA in FIG. In FIG. 2, above the carrier line 1 of the flask F containing the poured sand mold, a stopper body 2 for limiting the rise of the flask F at its lower end is provided.
A tubular guide tube 3 having a (see FIG. 1) attached thereto is fixedly arranged on the frames 4 and 4, and the transport line 1 for the flask F is provided.
A punch-out head 5 is provided below the guide cylinder 3 so as to face the guide cylinder 3.
Are arranged. A large number of sand removing pieces 6, 6 are attached to the outer periphery of the punch-out head 5.

Two pairs of bearings 7 and 7A are provided in front and back of the pair of bearings 7 and 7A at a position slightly wider than the lateral width of the mold F at both outer positions slightly below the conveying line 1 of the mold F. The rotary shafts 8 and 8 are fixedly arranged, and the rotary shafts 8 and 8 are supported between the pair of bearings 7 and 7A, respectively, and the rotary shafts 8 and 8 are rotatably supported at positions corresponding to the four corners of the casting frame through the brackets 9 and 9A. The bodies 10 and 10A are respectively erected, and each rotary support 1
0, 10A, 10 and 10A, the transfer line 1 for the flask F
Rotating roller bodies 11, 1 that are rotated up and down from below
1 is attached.

A downward short link 12 and an upward short link 13 are connected to both ends of the rotary shafts 8 and the tip of the downward short link 12 and the tip of the upward short link 13 rotate via a long link 14. Enabled and connected.

Further, one end of the rotary shafts 8 and 8 is located outside and above
The horizontal cylinder 15 is arranged and the horizontal cylinder 15 is arranged.
The piston rod 15A and one end of one of the rotary shafts 8 and 8 are rotatably connected via an intermediate link 16 to form a link mechanism as a whole, and the horizontal cylinder 1
The rotation shafts 8 and 8 are rotated by the operation of 5, and the four rotary roller bodies 11 and 11 are rotated and moved up and down.

The operation of the device thus configured will be described. 1 and 2 show a state in which a casting frame F containing a sand mold M that has been poured has been transferred from the transport line 1 of the casting frame F between the punch-out head 5 and the guide tube 3, There is a slight gap between the upper end surface of the frame F and the lower end of the stopper body 2.

In this state, the horizontal cylinder 15 is extended to operate, and the four rotary roller bodies 1 mounted on the rotary shafts 8, 8 are rotated.
The casting frames F are lifted from the transport line 1 by rotating and raising 1 and 11 via a link mechanism, and the upper surface of the casting frame F is pressed against the lower surface of the stopper body 2 to be fixed by pressing.

Next, the punch-out head 5 is operated to move upward to push up the poured sand mold M contained in the casting frame F, pull it out of the casting frame F, and raise it while being guided by the guide tube 3. Then, the molten sand mold M is moved laterally by a device (not shown) to move the punch-out head 5
To the original state (lower). At this time, the inner surface of the casting frame F is scraped off by the sand-removing pieces 6 to remove the foundry sand.

Then, the horizontal cylinder 15 is reversely operated, and the four rotary roller bodies 11 mounted on the rotary shafts 8 and 8,
11 is rotated down through a link mechanism to return the empty flask F to the transport line 1 and send it to the next step, and the flask F containing the new molten sand mold M is punched out by the punch-out head 5 The above-mentioned operation is repeated by carrying in above.

[0013]

As is apparent from the above description, the present invention raises a casting frame on a transfer line by a single cylinder through a special link mechanism and presses it against a stopper body to fix and pull it up. Since it is constructed so as to draw a frame, various effects can be obtained such that the leveling of the molding frame can be performed accurately and troubles in the piping and wiring of the cylinder can be minimized.
