Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a casting container holder used for casting zinc, lead, etc.

[Prior Art] For example, a casting container (ingot case) used for obtaining a zinc ingot is a container that opens upward and has a concave portion having a rectangular shape in plan view.
For example, 10 kg of molten metal is poured into each container.

When casting, first, the casting container is placed on a pedestal facing upward (opening upward), and molten metal is poured into the recess. Once the solution has solidified by leaving it to cool or forced cooling, the casting container is turned upside down and the solidified metal ingot is dropped and taken out.

[Problems to be Solved by the Invention] The above-mentioned work of inverting the casting container has the problem that the casting container is heavy and sagging at high temperatures, requiring a great deal of labor and being dangerous.

In order to improve this, a frame 52 that rotates around a horizontal axis of rotation 51 is provided on a base 53 as shown in FIG. 5
An inversion type casting device 50 has been developed that rotates the casting container 2 and pours the metal alternately into the upper and lower casting containers.
Although this device is easier to work with and safer than conventional ones, it still requires a considerable amount of effort as it requires rotating a frame to which many heavy casting containers filled with metal are attached by operating a handle. There was a problem.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides the following casting container holder.

That is, the casting container holder according to the present invention has a pair of receiving frames that support the casting container, and when one receiving frame is in the pouring position supporting the casting container upward, the other receiving frame supports the casting container downward. It is characterized in that it is provided symmetrically about the rotating shaft so that it is in an inverted position where it is supported by the support frame, and that it is provided with a stopper that stops the rotation of the receiving frame at a predetermined rotational position.

[Operation] With the casting container of one receiving frame facing upward, rotation is restrained by a stopper, and molten metal is poured into the casting container facing upward. When the molten metal solidifies after being left to cool or forced to cool for a predetermined period of time, the stopper is released. Then, the receiving frame on the poured side rotates downward due to gravity, which causes the receiving frame on the opposite side, to which the empty casting container is attached, to move upward. At this time, the receiving frame on the poured side rotates due to inertia until it is reversed downward, so that the ingot in the casting container is released by gravity. The rotated receiving frame is stopped at a predetermined position by a stopper. Repeated casting is possible in this way.

[Examples] Examples shown in the drawings will be described below.

In this casting container holder 1, a rotating shaft 5 is supported horizontally by bearings 3, 3 provided on the upper part of a base frame 2. The rotating shaft 5 has a pair of receiving frames 6 in its diametrical direction.
6' is attached. Seven casting containers (ingot cases) 7, . . . are attached to the receiving frames 6, 6', respectively. In Figure 1, the ingot cases 7,... attached to one receiving frame 6 are facing upward, and the ingot cases 7,... of the receiving frame 6' on the opposite side are facing downward in this position. However, when the rotating shaft 5 rotates 180 degrees, the ingot cases 7, ... on the receiving frame 6' side face upward,
Conversely, the ingot cases 7, . . . on the receiving frame 6 side face downward.

Auxiliary frames 9, 9' are attached to the rotating shaft 5 in a direction perpendicular to the receiving frames 6, 6'. Auxiliary frame 9,
The tip end of the support frame 9' and the tip end of the receiving frames 6, 6' are connected by inclined reinforcing members 10, 10.

A reversing stopper 2 for stopping the receiving frames 6, 6' in a horizontal state is provided on the reversing position R side of the casting container holder 1.
0 is set. The reverse stopper 20 is the third
As shown in the figure, a pair of mounting pieces 2 are provided at the outer end of the receiving member 21 that protrudes into the rotation locus of the receiving frames 6, 6'.
2 and 22 are pivotally connected to a protrusion 23 protruding outside the base frame 2 with a pin 24. Normally, the vertical plates 21a, 21a on both sides of the receiving member 21 are placed on the base frame 2 due to gravity, and at this time, the receiving member 20 is supported in a horizontal state, but there is no upward force. When the force is applied, the receiving member 21 rotates upward.

Further, a main stopper 30 is provided on the pouring position S side of the casting container holder 1 to support the bottoms of the holder frames 6, 6'. The main stopper 30 includes a bar 33 that is pivotally connected to a pedestal 31 extending from the base frame 2 toward the operator's side by a shaft 32, and the bar 33 is attached to the rotation axis as shown in FIG. 3d. 5, its tip protrudes into the locus of movement of the receiving frames 6, 6'; however, it can be rotated in a horizontal plane by grasping the front part (handle part) 33a of the bar 33. When this is done, the tip ends escape out of the movement trajectory of the receiving frames 6, 6'.

When using this casting container pedestal 1, molten metal is poured into the ingot cases 7, ... of the holder frame on the pouring position S side, which is supported horizontally while being placed on the main stopper 30. do. When pouring is completed, the molten metal is left to cool or is forced to cool until it solidifies, and when solidification is completed, the main stopper 30 is manually operated to remove the tip of the bar 33 from the bottom of the receiving frame 6, 6'. Then, the receiving frames 6, 6' rotate together with the rotating shaft 5 in the direction of arrow X due to the weight of the poured ingot cases 7,..., but when the ingot cases 7,... The ingot falls under its own weight, and the ingot case becomes empty, flips up the reversing stopper 20 by inertia, and passes above the reversing stopper. The flipped up reverse stopper 20 immediately returns to its original horizontal state due to its own weight, and the receiving frames 6, 6', which once passed upward, descend in the opposite direction of arrow X due to gravity and are placed on the reverse stopper 20. be done. Note that the main stopper 30 is returned to its original supporting state (a position perpendicular to the rotating shaft 5) immediately after the receiving frames 6, 6' holding the ingot case on the poured side are lowered, so that the main stopper 30 remains in the inverted position until then. Receiving frames 6', 6 having R are placed thereon. That is, the receiving frame is supported in a horizontal state by the main stopper 30 and the reverse stopper 20. Therefore, as in the previous case, the upward facing ingot case 7, which is in the pouring position,...
Just pour hot water inside.

As the reverse rotation stopper 20, instead of the hinge type illustrated example, a reverse rotation prevention device that allows rotation in only one direction, such as a ratchet mechanism, may be used.

[Effects of the invention] As is clear from the above explanation, the casting container holder according to the invention is structurally simple and robust, and is an excellent product that allows pouring work to be carried out safely, easily, and continuously. It became.
