Description

Technical Field

[0001] The invention belongs to the technical field of metal casting equipment, in particular to a mold for casting metal castings. Background Art

[0002] The molten metal is input between the upper and lower dies of the mold, and then the metal casting is obtained after the molten metal is cooled. However, since the temperature of the mold is low when it is used for the first time, it is easy to cause defects such as molding difficulties, sticking films, and casting cracks. After the molten metal enters the mold, the temperature changes too much and the cold and hot stresses are large, which can easily cause damage to the mold. In severe cases, the mold may even explode. Therefore, in order to protect the mold and improve the efficiency of the mold, a preheating device is used to preheat the mold so that the mold is always kept in a suitable temperature range.

[0003] Traditional casting molds generally use electric heaters to preheat the mold cavity. During processing, the electric heater needs to continuously preheat the mold cavity at a high power to prevent the temperature from changing too much after the molten metal enters the mold cavity, resulting in damage to the mold cavity. This is not economical. At the same time, in order to increase the molding speed of the casting, a cooling device is set up to cool the mold.

[0032] Two ventilation pipes 29 are fixedly connected to the top of the insulation shell 32, and the two ventilation pipes 29 are arranged opposite to each other. There are two circulation pipes 21, two water pumps 22, two motors 23, two telescopic pipes 24, and two fan blades 31. The two circulation pipes 21, two water pumps 22, two motors 23, two telescopic pipes 24, and two fan blades 31 are respectively located at the two ventilation pipes 29. The fan blades 31 are located in the inner cavity of the ventilation pipe 29, and the sealing plate 38 is in contact with the inner wall of the ventilation pipe 29.

[0033] The spring assembly 33 is composed of a damping telescopic rod 331 and a spring 332. The damping telescopic rod 331 is located at the center of the inner cavity of the spring 332. The top ends of the damping telescopic rod 331 and the spring 332 are fixedly connected to the lower pressure plate 34, and the bottom ends of the damping telescopic rod 331 and the spring 332 are fixedly connected to the bottom end of the inner cavity of the insulation shell 32.

[0034] A guide rod 362 is provided on one side of the threaded rod 361 , and the bottom end of the guide rod 362 is fixedly connected to the preheating and cooling chamber 25 . The pressing plate 37 is engaged with the surface of the threaded rod 361 , and the pressing plate 37 is movably sleeved on the surface of the guide rod 362 .

[0035] The bottom end of the pressing plate 37 is fixedly connected to the upper mold 5 , and the center of the upper mold 5 is fixedly connected to an input tube 6 , which passes through the upper mold 5 . The bottom end of the input tube 6 is located at the bottom end of the upper mold 5 , and the upper mold 5 is located above the lower mold 28 .

[0036] The circulation pipe 21 is connected to the inner cavity of the telescopic pipe 24 and the preheating and cooling chamber 25 through the water pump 22, and the two circulation pipes 21 are respectively connected to the input end and the output end of the cooler base 1.

[0037] In this embodiment, when in use, the inner cavity of the preheating and cooling chamber 25 is pre-filled with cold heat transfer oil, and then the heating rod 26 is started to heat the heat transfer oil in the inner cavity of the preheating and cooling chamber 25, and the temperature is detected in real time by the temperature sensor 27, so that the heat transfer oil is heated to a suitable temperature;

[0038] Then, the external molten metal input device is connected to the input pipe 6, and then the motor 2 35 is started to drive the threaded rod 361 to rotate. The pressing plate 37 is meshed with the threaded rod 361, thereby driving the pressing plate 37 to descend along the axis direction of the threaded rod 361 and the guide rod 362, and also driving the upper mold 5 to descend to the inner cavity of the lower mold 28. The pressing plate 37 descends and contacts the lower pressure column 341, and presses the lower pressure column 341 and the lower pressure plate 34 downward. When the lower pressure plate 34 is pressed, the spring assembly 1 33 contracts and accumulates elasticity. When the lower pressure plate 34 descends, it drives the sealing plate 38 to descend along the rotating shaft 41, and separates the sealing plate 38 from the ventilation pipe 29, thereby making the insulation shell 32 connected with the outside, so that the external cold air can enter the insulation shell 32 from the machine;

[0039] Then, the external molten metal input device transports the molten metal from the input pipe 6 to between the upper mold 5 and the lower mold 28. At the initial stage of the molten metal entering, the motor 23 is started to drive the rotating shaft 41 to rotate slowly to prevent the lower mold 28 from cooling due to excessive air flow and destroying the preheating effect.

[0040] When the molten metal is filled, the motor 23 is started to drive the rotating shaft 41 to rotate at a high speed, and the water pump 22 is operated, so that the cold heat transfer oil in the inner cavity of the cooler base 1 is input into the inner cavity of the preheating and cooling bin 25 along the telescopic tube 24 through the circulation pipe 21, and the heat transfer oil in the inner cavity of the preheating and cooling bin 25 is extracted through another water pump 22, so that the heat transfer oil in the inner cavity of the preheating and cooling bin 25 and the cooler base 1 circulates, cools the molten metal in the lower mold 28, and accelerates the molding of the casting;

[0041] The high-speed rotation of the rotating shaft 41 drives the fan blades 31 to rotate at a high speed, generating wind force to blow into the inner cavity of the heat preservation shell 32, and then the air in the inner cavity of the heat preservation shell 32 is discharged through another fan blade 31, so that the wind force of the two fan blades 31 causes the air in the inner cavity of the heat preservation shell 32 to flow at a high speed, thereby assisting the preheating and cooling bin 25 in cooling and dissipating heat, further enhancing the cooling efficiency of the metal melt in the inner cavity of the lower mold 28, allowing it to be quickly formed, and realizing that during the casting process, the heat preservation shell 32 can be used for centralized wind guidance, so that the high-speed flowing air can evenly contact the outer side of the preheating and cooling bin 25, thereby improving the molding of the casting and accelerating the production efficiency;

[0042] After the molten metal in the inner cavity of the lower mold 28 is formed into a casting, the water pump 22 stops running, so that the heat transfer oil in the inner cavity of the preheating and cooling chamber 25 no longer circulates, thereby realizing that the heat generated during casting is used to heat the heat transfer oil in the preheating and cooling chamber 25. The heated heat transfer oil can be used to preheat the lower mold 28 for the next casting, without the need for the heating rod 26 to continuously heat the heat transfer oil.

[0043] Then the motor 1 23 stops running, and then the motor 2 35 is started to drive the threaded rod 361 to run, thereby driving the pressing plate 37 to rise along the axis direction of the threaded rod 361 and the guide rod 362, and then the casting is taken out from the inner cavity of the lower mold 28;

[0044] When the pressing plate 37 rises, the spring assembly 33 loses its limit, and the extended release elasticity drives the lower pressing plate 34 to rise and reset, thereby driving the sealing plate 38 to rise and fit the inner wall of the ventilation pipe 29 again, so that the inner cavity of the insulation shell 32 is sealed. After the casting is completed, the sealed insulation shell 32 is used to keep the temperature of the heat transfer oil in the preheating and cooling chamber 25 warm. When the interval between two castings is long or extremely long, the heating rod 26 does not need to be operated, and the heat transfer oil in the preheating and cooling chamber 25 can keep the lower mold 28 preheated. Alternatively, the heating rod 26 only needs to be operated at extremely low power to cooperate with the insulation of the insulation shell 32 to keep the lower mold 28 preheated, making the entire casting process more economical.

[0045] like Figures 1 to 6 As shown, an embodiment of the present invention provides a mold for casting metal castings, and the knocking mechanism 4 also includes a spring component 2 42, and the spring component 2 42 is fixedly connected to the bottom end of the rotating shaft 41, and a knocking rod 43 is fixedly connected to the side of the spring component 42 away from the rotating shaft 41, and a fixed rod 44 is fixedly connected to the outer side of the preheating and cooling chamber 25 near the knocking rod 43, and the bottom end of the preheating and cooling chamber 25 is fixedly connected to the spring component 3 45.

[0046] The spring assembly 42 is composed of a damping telescopic rod 421 and a spring 422. The damping telescopic rod 421 is located at the center of the inner cavity of the spring 422. The two ends of the damping telescopic rod 421 and the spring 422 are fixedly connected to the rotating shaft 41 and the knocking rod 43 respectively. The fixed rod 44 is located on the moving path of the knocking rod 43.

[0047] The spring assembly 3 45 is composed of a damping telescopic rod 3 451 and a spring 3 452. The damping telescopic rod 3 451 is located at the center of the inner cavity of the spring 3 452. The bottom ends of the damping telescopic rod 3 451 and the spring 3 452 are fixedly connected to the bottom end of the inner cavity of the heat preservation shell 32. The top of the inner side of the heat preservation shell 32 is in contact with the top of the outer side of the preheating and cooling chamber 25.

[0048] In this embodiment, at the initial stage when the molten metal enters between the upper mold 5 and the lower mold 28, the rotating shaft 41 will run slowly. At this time, due to the slow rotation speed of the rotating shaft 41, the centrifugal force on the knocking rod 43 is small, and thus it cannot overcome the pulling force of the spring 2 422, so the knocking rod 43 is close to the rotating shaft 41. At this time, the fixed rod 44 is located on the moving path of the knocking rod 43, and as the rotating shaft 41 rotates, the knocking rod 43 and the fixed rod 44 are driven to contact intermittently. When the knocking rod 43 contacts the fixed rod 44, the fixed rod 44 is pressed downward, thereby driving the preheating and cooling chamber 25 to move downward. At this time, the spring component 3 45 contracts and accumulates force. When the knocking rod 43 separates from the fixed rod 44, the spring component 3 45 loses its limit, and stretches to release its elasticity to drive the lower mold 28 to vibrate slightly, thereby making the molten metal between the upper mold 5 and the lower mold 28 more tightly filled, and eliminating bubbles in the molten metal;

[0049] When the molten metal fills the space between the upper mold 5 and the lower mold 28, the motor 1 23 drives the rotating shaft 41 to rotate at a high speed. At this time, the centrifugal force on the knocking rod 43 is relatively large, thereby overcoming the pulling force of the spring 2 422, so that the knocking rod 43 moves away from the rotating shaft 41, and then the fixed rod 44 is no longer located on the moving path of the knocking rod 43. At this time, the preheating and cooling chamber 25 no longer vibrates;

[0050] After the casting in the inner cavity of the lower mold 28 is formed, the motor 23 no longer needs to drive the fan blades 31 to cool down, and the rotating shaft 41 reduces its rotation speed. At this time, the centrifugal force applied to the knocking rod 43 is small, so it is pulled back by the spring assembly 2 42, so that the fixed rod 44 is again located on the moving path of the knocking rod 43, and then the knocking rod 43 contacts the fixed rod 44 to knock on the preheating and cooling bin 25, so that the casting is quickly separated from the inner wall of the lower mold 28, thereby improving the blanking efficiency.

[0051] Working principle and use process: the inner cavity of the preheating and cooling chamber 25 is filled with heat-conducting oil. When used for the first time, the heating rod 26 is started to heat the heat-conducting oil in the inner cavity of the preheating and cooling chamber 25, thereby preheating the preheating and cooling chamber 25, and the temperature is detected by the temperature sensor 27;

[0052] Then, the external input device is connected to the input pipe 6, and then the motor 2 35 is started to drive the threaded rod 361 to rotate, thereby driving the pressing plate 37 engaged therewith to move downward, so that the upper mold 5 is lowered to the inner cavity of the lower mold 28. At this time, the pressing plate 37 contacts and presses the lower pressing column 341, driving the lower pressing plate 34 to move downward. The downward movement of the lower pressing plate 34 drives the sealing plate 38 to move downward along the rotating shaft 41 in a large range, thereby making the insulation shell 32 connected with the outside, so that the external cold air can enter the insulation shell 32, and then the molten metal is input from the input pipe 6 into the space between the lower mold 28 and the upper mold 5;

[0053] In the early stage when the molten metal is input between the lower mold 28 and the upper mold 5, the starting motor 1 23 drives the rotating shaft 41 to rotate slowly. The rotating shaft 41 with a slower rotation speed drives the knocking rod 43 to rotate. The centrifugal force on the knocking rod 43 is small, so the spring component 2 42 will not extend. At this time, the knocking rod 43 is in contact with the spring component 2 42, and through the rotation of the knocking rod 43, the knocking rod 43 is intermittently in contact with the fixed rod 44. When the knocking rod 43 and the fixed rod 44 are in contact, the fixed rod 44 is driven to move downward, and the spring component 3 45 contracts and accumulates force. When the knocking rod 43 and the fixed rod 44 are separated, the spring component 3 45 extends and releases elasticity to drive the lower mold 28 to vibrate slightly, thereby discharging bubbles and making the molten metal and the upper mold 5 and the lower mold 28 more tightly filled;

[0054] After vibrating for many times, the space between the upper mold 5 and the lower mold 28 is filled with molten metal, the motor 1 23 drives the rotating shaft 41 to rotate at a high speed, and the water pump 22 operates, so that the cold heat transfer oil in the inner cavity of the cooler base 1 is input into the inner cavity of the preheating and cooling bin 25 along the telescopic tube 24 through the circulation pipe 21, and the heat transfer oil in the inner cavity of the preheating and cooling bin 25 is extracted through another water pump 22, so that the heat transfer oil in the inner cavity of the preheating and cooling bin 25 and the cooler base 1 circulates, cools the molten metal in the lower mold 28, and accelerates the molding of the casting;

[0055] The rotating shaft 41 rotates at a high speed, the centrifugal force on the knocking rod 43 is large, the spring assembly 2 42 extends, so that the knocking rod 43 and the fixing rod 44 are no longer in contact, the vibration of the lower mold 28 stops, and the heat preservation shell 32 is connected to the outside, and the wind force generated by the fan blade 31 is blown into the inner cavity of the heat preservation shell 32, and then the air is discharged through another fan blade 31, thereby assisting the heat dissipation of the preheating and cooling chamber 25;

[0056] The molten metal in the inner cavity of the lower mold 28 is cooled by cold heat transfer oil to form it quickly. After forming, the rotation speed of the rotating shaft 41 is reduced again, and the water pump 22 is stopped from circulating, so that the heat transfer oil in the inner cavity of the preheating and cooling chamber 25 is no longer circulated, and the heat transfer oil in the inner cavity of the preheating and cooling chamber 25 is continuously heated by the casting;

[0057] At this time, the knocking rod 43 and the fixing rod 44 are in intermittent contact again, so that the preheating and cooling chamber 25 vibrates, so that the casting can be quickly separated from the upper mold 5 and the lower mold 28;

[0058] Then, the motor 2 35 is started to drive the threaded rod 361 to rotate, thereby driving the upper mold 5 to rise, and then the casting is taken out, and the pressing plate 37 is separated from the lower pressing plate 34, and then the sealing plate 38 is driven to rise by the thrust of the spring assembly 1 33 to block the rotating shaft 41, and at this time, the inner cavity of the heat preservation shell 32 is sealed;

[0059] At this time, the lower mold 28 is continuously preheated by the heat-conducting oil in the inner cavity of the preheating and cooling chamber 25 to prepare for the next use, and the preheating and cooling chamber 25 is insulated by the sealed insulation shell 32.
