[0011] Compared with the prior art, the present invention provides a casting device for metal processing, which has the following beneficial effects: the casting device for metal processing can block the feed pipe by introducing the molten metal into the storage box, and then

[0012] The lifting bar can be driven upward by two cylinders, so that each lifting tube can be driven upward, and the baffle can be driven upward, so that the baffle will be away from the feeding tube, and the molten metal will flow into the round box through the gap between the baffle and the feeding tube. When the round box is full, the lifting tube can be driven downward by the cylinder, so that the baffle can be driven downward to block the feeding tube, so that the discharge tube can be opened, and a certain amount of molten metal can be injected into the mold. Quantitative injection avoids waste and prevents users from carrying containers to pour molten metal into the mold one by one.

[0013] The casting device for metal processing injects molten metal into the round box by moving the lifting bar upwards, and at the same time drives the horizontal bar upwards through the two vertical bars, so that each movable tube can be driven to move upwards, so that each round block can be driven to move upwards. When the round block moves upwards to block the conical tube b, it will block the feed pipe, so that the injected molten metal can be prevented from flowing downwards. When the round box is full, the lifting bar is moved downwards and the movable tube can be driven downwards, so that the round block can be moved downwards, so that the molten metal will flow downwards, so that the feed pipe can be closed when the molten metal is injected into the round box, and when it is full, the feed pipe can be opened while blocking the discharge pipe.

[0014] The casting device for metal processing moves the baffle upward to allow the molten metal to enter the round box, and the baffle moves upward away from the short column, so that the vertical pipe will be connected with the feed pipe, and the air in the round box will be discharged from the vertical pipe, so as to avoid the air in the round box not being able to be discharged quickly and affecting the injection of the molten metal. When the round box is full, the baffle moves downward to fit with the short column to close the lower end of the vertical pipe.

[0015] The casting device for metal processing can slide out the half-frame block after the four vertical rods are separated from the connecting grooves by moving upwards, so that the lifting strips and other mechanisms can be moved upwards to be removed, thereby facilitating replacement by users, so that round boxes of different capacities can be replaced according to needs.

[0016] The casting device for metal processing can protect two cylinders through two round barrels, so as to prevent the splashing molten metal from damaging the cylinders when the molten metal is injected into the storage box. When the lifting bar moves upward, it will drive the shielding ring to move upward to block the air groove. When the lifting bar moves downward, it will drive the shielding ring to move downward to expose the air groove. In this way, when the molten metal in the round box flows downward, air will be quickly injected into the round box to accelerate the downward flow speed of the molten metal.

[0017] 6.

By introducing the molten metal into the storage box 12 to block the feed pipe 27, the lifting bar 24 can be driven to move upward by two cylinders 10, so that each lifting tube 23 can be driven to move upward, so that the baffle 34 can be driven to move upward, so that the baffle 34 will be away from the feed pipe 38, so that the molten metal will flow into the round box 16 through the gap between the baffle 34 and the feed pipe 38. When the round box 16 is full, the lifting tube 23 can be driven downward by the cylinder 10, thereby driving the baffle 34 to move downward to block the feed tube 38, so that the discharge tube 27 can be opened, thereby injecting a quantitative amount of molten metal into the mold.

The two round barrels 11 can protect the two cylinders 10, and can prevent the metal liquid splashed out when the molten metal is injected into the storage box 12 from damaging the cylinder 10. When the lifting bar 24 moves upward, it will drive the shielding ring 25 to move upward to block the air groove 39. When the lifting bar 24 moves downward, it will drive the shielding ring 25 to move downward to expose the air groove 39. In this way, when the molten metal in the round box 16 flows downward, air will be quickly injected into the round box 16 to accelerate the speed of the molten metal flowing downward.Several partitions 3 are fixedly installed on the upper side of the bottom plate 1, and several molds 4 are respectively arranged between the several partitions 3.

The rotating tube 18 on each cross bar 17 can facilitate users to slide the mold 4 on the bottom plate 1, thereby improving the practicality of the device.

[0027] When in use, the first step is to guide the molten metal into the storage box 12 to block the feed pipe 27, and then the two cylinders 10 can drive the lifting bar 24 to move upward, so that each lifting tube 23 can be driven to move upward, so that the baffle 34 can be driven to move upward, so that the baffle 34 will be away from the feed pipe 38, so that the molten metal will flow into the round box 16 through the gap between the baffle 34 and the feed pipe 38. When the round box 16 is full, the cylinder 10 can drive the lifting tube 23 to move downward, so that the baffle 34 can be driven to move downward to block the feed pipe 38, so that the feed pipe 27 can be opened, so that a certain amount of molten metal can be injected into the mold. Quantitative injection avoids waste and prevents users from carrying containers to pour molten metal into the mold one by one.

[0028] Step 2: When the molten metal is injected into the round box 16 by moving the lifting bar 24 upward, the two vertical bars 6 drive the horizontal bar 5 to move upward at the same time, so that each movable tube 29 can be driven to move upward, so that each round block 31 can be driven to move upward. When the round block 31 moves upward to block the conical tube b30, it will block the feed pipe 27, so as to prevent the injected molten metal from flowing downward. When the round box 16 is full, the lifting bar 24 is moved downward, and the movable tube 29 can be driven downward, so that the round block 31 can be moved downward, so that the molten metal will flow downward, so that the feed pipe 27 can be closed when the molten metal is injected into the round box 16, and when it is full, the feed pipe 27 can be opened while blocking the discharge pipe 22.

[0029] Step 3: When the baffle 34 moves upward to allow the molten metal to enter the round box 16, the baffle 34 moves upward away from the short column 36, so that the vertical pipe 15 will be connected with the feeding pipe 38, so that the air in the round box 16 will be discharged from the vertical pipe 15, so as to avoid the air in the round box 16 not being able to be quickly discharged and affecting the injection of the molten metal. When the round box 16 is full, the baffle 34 moves downward to fit with the short column 36 to close the lower end of the vertical pipe 15.

[0030] Step 4: After the four vertical rods 43 are moved upward to separate from the connecting grooves 46, the half frame block 44 can be slid out, and the lifting bar 24 and other mechanisms can be moved upward to be removed, so that the user can replace them conveniently, and the round box 16 of different capacity can be replaced according to needs.

[0031] Step 5: The two round barrels 11 can protect the two cylinders 10, and can prevent the splashed molten metal from damaging the cylinders 10 when the molten metal is injected into the storage box 12. When the lifting bar 24 moves upward, it will drive the shielding ring 25 to move upward to block the air groove 39. When the lifting bar 24 moves downward, it will drive the shielding ring 25 to move downward to expose the air groove 39. In this way, when the molten metal in the round box 16 flows downward, air will be quickly injected into the round box 16 to accelerate the downward flow speed of the molten metal.

[0032] Step 6: The partition 3 and the back plate 21 can facilitate users to position each mold 4, the limiting groove 20 and the limiting bar 2 can facilitate users to fix the mold 4, and the rotating tube 18 on each cross bar 17 can facilitate users to slide the mold 4 on the bottom plate 1, thereby improving the practicality of the device.
