Description

Technical Field

[0001] The utility model belongs to the technical field related to casting machines, and specifically relates to a tilting gravity casting machine. Background Art

[0002] Metal casting (such as aluminum casting) often uses two upper and lower half molds to set half mold cavities respectively. The two half molds are matched to form a complete mold cavity. During casting, the mold is first tilted, and the molten metal is injected from the mold cavity opening. During the process of molten metal injection, the mold is gradually straightened to achieve the molten metal flowing down the mold cavity wall. After cooling and forming, the two half molds are separated to take out the cast blank.

[0003] Usually, aluminum liquid needs to be poured manually during the casting process, which not only increases the workload of the staff, but also causes instability in the manual control of the tilt of the ladle, which can easily lead to safety accidents and endanger the personal safety of the staff. The existing casting device cannot accurately control the pouring amount of aluminum liquid during use, which can easily cause leakage of aluminum liquid and affect the casting quality. Therefore, a tilting gravity casting machine is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a tilting gravity casting machine, comprising a fixed plate 2, a limit frame 16 is fixedly connected to the top of the fixed plate 2, a tilting oil cylinder 1 is arranged inside the limit frame 16, a support plate 3 is also fixedly connected to the top of the fixed plate 2, a rotating shaft 4 is rotatably connected to the inside of the support plate 3, a mounting plate 15 is fixedly connected to the surface of the rotating shaft 4, and a casting mechanism for casting is arranged on the surface of the mounting plate 15;

[0023] The casting mechanism includes a die bin 10, a plurality of die push plates 14 are arranged on the side of the die bin 10, a pressing plate 12 is arranged on one side of the die push plate 14, a pressing hydraulic cylinder 13 is arranged on one side of the pressing plate 12, and a shell 5 is fixedly connected to the surface of the pressing hydraulic cylinder 13.

[0024] In order to facilitate casting, while reducing the work intensity of the staff, the personal safety of the staff can be improved, and the aluminum liquid can be poured at a set flow rate, which can effectively improve the quality of casting. The shell 5 is fixedly connected to the mounting plate 15, and a fixing frame 11 is fixedly connected to the surface of the shell 5 above the mounting plate 15. The interior of the fixing frame 11 is rotatably connected to an articulated cantilever 6 through a pin shaft, and two groups of first hydraulic cylinders 7 are fixedly installed on both sides below the articulated cantilever 6.

[0025] In order to facilitate the pouring of molten aluminum into the die bin 10 , one end of the first hydraulic cylinder 7 is fixedly connected to the top mold cylinder 8 , the surface of the die bin 10 is fixedly connected to a ladle 9 , and one end of the ladle 9 is fixedly connected to a drainage groove 17 .

[0026] In order to facilitate the casting of different molds and effectively improve the application scope of the casting mechanism, the mold is detachably connected to the inside of the die bin 10, the die push plate 14 is slidably connected to the die bin 10, and a reset element is arranged between the die push plate 14 and the die bin 10.

[0027] In order to improve the stability of the device during operation and facilitate casting, the tilting cylinder 1 and the limit frame 16 are rotatably connected through a pin shaft. Two groups of tilting cylinder 1, support plate 3 and limit frame 16 are arranged above the fixed plate 2. The drainage trough 17 and the ladle 9 are made of high-strength and high-temperature resistant materials.

[0028] In order to facilitate the pressing of different molds and casting, the outer shell 5, the pressing plate 12 and the pressing hydraulic cylinder 13 are evenly distributed in four groups at a ninety-degree angle on the outside of the die bin 10. A rubber pad is provided on one end face of the pressing plate 12 close to the die push plate 14, and a rubber pad is also provided on one end face of the top clamping cylinder 8 close to the die bin 10.

[0029] Furthermore, the articulated cantilever 6 and the fixing frame 11 are both made of lightweight steel material.

[0030] Furthermore, the speed of the tilting cylinder 1 can be digitally set between 20% and 100% through the touch screen.

[0031] The working principle and use process of the utility model are as follows: after the utility model is installed, the articulated cantilever 6 is first pulled by the crane to flip inside the fixed frame 11. At this time, the flipping of the articulated cantilever 6 drives the first hydraulic cylinder 7 and the top mold closing cylinder 8 to flip, which can facilitate the manual placement of the sand core and put the target mold into the inside of the die bin 10. Then, the multiple groups of pressing hydraulic cylinders 13 are started to move the pressing plate 12 inwardly. The movement of the pressing plate 12 can push the die push plate 14 to move into the inside of the die bin 10, and the mold inside it can be pressed, which is convenient for subsequent casting. Then, the articulated cantilever 6 is flipped again, so that the top mold closing cylinder 8 is located in front of the die bin 10, and the top of the die bin 10 is pressed. It can not only save the working time of the staff, but also effectively reduce the working intensity of the staff;

[0032] When the die pressing is completed, the tilting cylinder 1 is started to push the mounting plate 15 to rotate. When the mounting plate 15 rotates, it drives the rotating shaft 4 to rotate inside the supporting plate 3. At this time, the mounting plate 15 is in a vertical state, and the ladle 9 is in a horizontal state, which is convenient for the robot to pour the molten aluminum liquid into the ladle 9 through the drainage groove 17, and convenient for the subsequent pouring of the aluminum liquid into the mold inside the die chamber 10 for casting;

[0033] After the molten aluminum liquid is added to the inside of the ladle 9, the tilting cylinder 1 is started again to drive the mounting plate 15 to flip around the rotating shaft 4. The angle during the flipping process is controlled by the tilting cylinder 1, which can achieve a smooth tilting between 0-90 degrees without obvious shaking, and will not cause the aluminum liquid inside the ladle 9 to leak. When the mounting plate 15 gradually and steadily tilts, the aluminum liquid inside the ladle 9 will slowly flow to the mold inside the die bin 10 for pouring. When the pouring is completed, the staff will remove the sand core and the target mold again to complete the workpiece casting.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
