Abstract

A casting apparatus of a casting equipment includes an upper frame to which an upper mold is attached, a lower frame to which a lower mold is attached, a mold closing mechanism, a pair of main link members each of which has a central portion provided with a rotating shaft, a pair of auxiliary link members each of which has a central portion provided with a rotating shaft, and a drive means. The upper frame, the lower frame, the main link member, and the auxiliary link member constitute a parallel link mechanism.

First claim

The invention claimed is:

1. Casting equipment comprising:
a casting apparatus that forms a casting by using an upper mold and a lower mold, which can be opened, closed, and tilted, into which molten metal is poured by using gravity;
a holding furnace that stores the molten metal to be used in the casting apparatus; and
a pouring apparatus that transfers the molten metal to the casting apparatus from the holding furnace and pours the molten metal into the casting apparatus,
the casting apparatus including:
an upper frame to which an upper mold is attached;
a lower frame to which a lower mold is attached;
a mold closing mechanism that is provided in the upper frame to move the upper mold up and down, or that is provided in the lower frame to move the lower mold up and down;
a pair of main link members each of which has upper and lower ends that are rotatably coupled to the upper and lower frames, respectively, to be oppositely arranged, and has a central portion that is provided with a rotating shaft;
a pair of auxiliary link members arranged parallel to the respective main link members, and each of which has upper and lower ends that are rotatably coupled to the upper and lower frames, respectively, to be oppositely arranged, and has a central portion that is provided with a rotating shaft; and
a drive means that is provided to be coupled to the rotating shaft of one of the pair of main link members, and that tilts the upper mold and the lower mold or horizontally moves the molds away from each other,
wherein the upper frame, the lower frame, the main link member, and the auxiliary link member constitute a parallel link mechanism.

2. The casting equipment according to claim 1 , wherein the casting apparatus further includes a ladle attached to the lower mold,
the ladle including:
a storage section formed inside the ladle for storing molten metal; and
a pouring port connected to a receiving port of the lower mold,
and wherein the pouring apparatus pours the molten metal into the ladle when the upper mold and the lower mold are closed by the mold closing mechanism to become a mold closed state.

3. The casting equipment according to claim 2 , wherein the pouring apparatus and the casting apparatus are communicatively connected to each other, and wherein the casting apparatus outputs information showing the mold closed state to the pouring apparatus when the upper mold and the lower mold are in the mold closed state, and then the pouring apparatus does not pour the molten metal into the ladle when receiving no information from the casting apparatus.

4. The casting equipment according to claim 3 , wherein the ladle is attached to the lower mold while inclined in a tilt direction in which the upper mold and the lower mold are tilted.

5. The casting equipment according to claim 3 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

6. The casting equipment according to claim 3 , comprising a plurality of the casting apparatuses,
wherein the pouring apparatus transfers and pours the molten metal to each of the plurality of casting apparatuses from the holding furnace.

7. The casting equipment according to claim 2 , wherein the ladle is attached to the lower mold while inclined in a tilt direction in which the upper mold and the lower mold are tilted.

8. The casting equipment according to claim 7 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

9. The casting equipment according to claim 2 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

10. The casting equipment according to claim 2 , comprising a plurality of the casting apparatuses,
wherein the pouring apparatus transfers and pours the molten metal to each of the plurality of casting apparatuses from the holding furnace.

11. The casting equipment according to claim 1 , wherein the casting apparatus further includes a ladle attached to the lower mold,
the ladle including:
a storage section formed inside the ladle for storing molten metal; and
a pouring port connected to a receiving port of the lower mold, wherein after the upper mold and the lower mold are opened by the mold closing mechanism, the pouring apparatus pours the molten metal into the ladle when the upper mold is moved in a direction away from the pouring apparatus and the lower mold is moved in a direction approaching the pouring apparatus, by the drive means, to become a first separation state where the upper mold and the lower mold are horizontally separated from each other.

12. The casting equipment according to claim 11 , wherein the pouring apparatus and the casting apparatus are communicatively connected to each other, and wherein the casting apparatus outputs information showing the first separation state to the pouring apparatus when the upper mold and the lower mold are in the first separation state, and then the pouring apparatus does not pour the molten metal into the ladle when receiving no information from the casting apparatus.

13. The casting equipment according to claim 12 , wherein the ladle is attached to the lower mold while inclined in a tilt direction in which the upper mold and the lower mold are tilted.

14. The casting equipment according to claim 12 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

15. The casting equipment according to claim 11 wherein the ladle is attached to the lower mold while inclined in a tilt direction in which the upper mold and the lower mold are tilted.

16. The casting equipment according to claim 11 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

17. The casting equipment according to claim 11 , comprising a plurality of the casting apparatuses,
wherein the pouring apparatus transfers and pours the molten metal to each of the plurality of casting apparatuses from the holding furnace.

18. The casting equipment according to claim 1 , wherein the pouring apparatus starts transferring the molten metal before the casting apparatus is ready to receive the molten metal.

19. The casting equipment according to claim 1 , comprising a plurality of the casting apparatuses, wherein the pouring apparatus transfers and pours the molten metal to each of the plurality of casting apparatuses from the holding furnace.

20. The casting equipment according to claim 1 , wherein the pouring apparatus includes a receiving unit that receives a casting from the upper mold, and wherein after the upper mold and the lower mold are opened by the mold closing mechanism, the receiving unit receives a casting from the upper mold when the lower mold is moved in the direction away from the pouring apparatus and the upper mold is moved in the direction approaching the pouring apparatus, by the drive means, to become a second separation state where the upper mold and the lower mold are horizontally separated from each other.
