[0039] Implementation Methods of the Application

[0040] In order to further understand the features, technical means, and specific objectives and functions achieved by this application, this application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] 1 to 9 : A fully automatic negative pressure casting device for aluminum ingots, comprising a casting unit 1, the casting unit 1 comprising a casting chamber 11, a mold clamping control mechanism 2 and a mold locking mechanism 3; the mold clamping control mechanism 2 is provided with a detection unit for detecting the mold clamping stroke and the detection unit is provided with a first detection position, a second detection position and a third detection position equidistantly along the mold clamping direction; when the movable module 13 slides toward the casting chamber 11, when the movable module 13 slides to the first detection position, the system issues an alarm, and except for the movable module 13 being able to rise and fall, the rest of the casting equipment is in a locked state; when the movable module 13 slides to the second detection position, it is adjusted to a decelerated rising state; when the movable module 13 slides to the third detection position, it is adjusted to an extremely slow rising state; in order to ensure the stability and accuracy of the mold clamping degree; a mold plate cover 12 is also flipped and set on one side above the casting chamber 11, and the mold plate cover 12 is driven and controlled by a locking mechanism 3 fixedly set at one end of the casting chamber 11; the mold cover plate is hingedly connected to the casting chamber 11 through a flip bracket 14; the locking mechanism 3 is used to realize the flip cover of the mold plate cover 12 in the casting state and to be set on the casting chamber 11, and to flip and open the mold plate cover 12 in the non-casting state; the locking mechanism 3 is provided with an actuator arm 31 coaxially fixed at the shaft head of the flip bracket 14 and a linear drive 32 for driving the axis of the actuator arm 31 to flip circumferentially along the flip axis of the flip bracket 14, and the linear drive 32 has a circumferential fixing element 33 for pre-locking the driving stroke of the linear drive 32 before the driving state.

[0042] Since there cannot be non-productive water accumulation at the smelting and casting operation site, the water sealing requirements of the equipment are very high, so the following ground water supply device 4 is used for water supply at the water inlet; the ground water supply device 4 consists of a mounting base 41, a docking flange 42, a dust shield 43, a flexible joint 44, a compression spring 45, an adjusting pad 46, a dust cover 47 and a torsion spring 48; one end of the flexible joint 44 is mounted on the mounting base 41, and the other side is fixedly connected to the docking flange 42, and a compression spring 45 is installed under the docking flange 42, which is adjusted by The pad 46 adjusts the compression spring 45 to provide an upward thrust to the flexible joint 44; when the mobile trolley 15 moves towards the casting station, the water inlet of the mobile trolley 15 pushes open the rotatable dust shield 43. After the mobile trolley 15 moves into position, the water outlet of the mobile trolley 15 is pressed down and combined with the docking flange 42. The downward pressure of the water outlet and the compression spring 45 provide an upward thrust to the flexible joint 44 to ensure the sealing of the docking water outlet; after the casting is completed, the trolley leaves the casting station, and the rotatable dust shield 43 is restored to its original position by the torsion spring 48 to prevent debris from entering the water supply port.

[0043] As shown in Figure 6: the mold clamping control mechanism 2 includes a movable detection unit 21 and a fixed detection unit 22; the movable detection unit 21 is horizontally arranged vertically on one side of the movable mold group and the detection end is radially arranged toward the side away from the movable mold group; the movable detection unit 21 is provided with a movable detection head and the detection head is telescopically adjustable; the fixed detection unit 22 is vertically fixedly arranged on one side of the equipment frame adjacent to the movable detection unit 21.

[0044] In the working state, the movable module 13 is lifted up at a relatively fast speed under the jacking of the lifting device 16 oil cylinder. When the movable module 13 moves up, it will synchronously drive the active detection unit 21 to rise. During the continuous upward movement, when the movable unit approaches the fixed detection unit 22 vertically arranged on the equipment frame, the fixed detection unit 22 detects that the movable detection unit 21 in the upward movement is at the first detection position. The movable detection unit 21 continues to move up, and the fixed detection unit 22 sends an early warning signal to the system. Except for the movable module 13, the rest of the casting equipment is in a locked state. The active detection unit 22 is close to the fixed detection unit 22 vertically arranged on the equipment frame. 1 continues to move upward, and when it moves to the second detection position, the fixed detection unit 22 sends a control signal to the lifting device 16 to drive it to decelerate and rise in a decelerated state; when the movable detection unit 21 continues to move upward, and when it moves to the third detection position, the fixed detection unit 22 again sends a deceleration signal to the lifting device 16 to drive it to rise at an extremely slow speed; until the movable module 13 is molded with the mold surface of the casting chamber 11 and stops. By controlling the lifting of the movable module 13 in stages, the mold closing efficiency can be effectively maintained while ensuring the stability of the mold closing, avoiding mold collision caused by excessive mold closing speed and liquid leakage caused by inadequate mold closing.

[0045] See Figures 2, 3, 6 and 7: the activity detection unit 21 includes a fixed sleeve rod 211, an adjusting rod 212, an extension rod 213 and a second sensor element; the fixed sleeve rod 211 is vertically fixed to one side of the dynamic module 13 through a fixed base plate; the adjusting rod 212 is slidably set in the fixed sleeve rod 211 and passes through the end of the fixed sleeve rod 211 and is set toward the outside; the extension rod 213 is vertically set at the end of the adjusting rod 212 and the end of the extension rod 213 is extended toward the ground; the second sensor element is a split displacement sensor, which consists of a sensing block 214 and a sensing base 215, which can display the position in real time; the sensing block 214 of the second sensor element is fixed at the end of the extension rod 213.

[0046] In the working state, since the adjusting rod 212 is slidably arranged in the fixed sleeve rod 211, the adjusting rod 212 can be flexibly telescopically adjusted according to the detection requirements and the installation position of the active detection unit 21, so that its sensing block 214 can be set in contact with the fixed detection unit 22 to the greatest extent, thereby presenting a more sensitive and accurate detection effect.

[0047] The sensing block 214 is used to cooperate with the fixed detection unit 22 to provide the fixed detection unit 22 with the lifting position of the moving module 13 in real time, thereby achieving precise control of the lifting height of the moving module 13.

[0048] Referring to Figures 2, 3, 6 and 7: the fixed detection unit 22 includes a mounting slot 221, a first sensor element 222, a sensing base 215, a third sensor element 223 and an adjustment plate 224; the first sensor element 222, the sensing base 215 and the third sensor element 223 are movably installed on one side of the mounting slot 221 close to the movable detection unit 21 through the adjustment plate 224, and the first sensor element 222, the sensing base 215 and the third sensor element 223 are respectively arranged near the upper, middle and lower positions of the mounting slot 221; thereby forming the first detection position, the second detection position and the third detection position respectively.

[0049] In the working state, when the moving module 13 moves vertically upward under the drive of the lifting device 16, the activity detection unit 21 fixed on one side of the moving module 13 is synchronously driven to move upward. When the moving module 13 moves to the first sensor element 222, the first sensor element 222 warns the system that except for the moving module 13, the rest of the casting equipment is in a locked state; after the induction block 214 is detected by the induction base 215, it will transmit a control signal to the lifting device 16, thereby driving the lifting device 16 to execute the corresponding deceleration instruction, so as to realize flexible control of the lifting speed of the lifting device 16 and to enable the moving module 13 to accurately reach the mold closing position every time through the data comparison of the two sets of second induction elements; due to the first sensor element 222, the induction base 215 and The third sensing element 223 is fixedly arranged on one side of the mounting groove 221 by an adjustment plate 224. When the detection point needs to be adjusted, the installation position of the first sensing element 222, the sensing base 215 and the third sensing element 223 can be changed by sliding and adjusting the adjustment plate 224; the first detection position: at the sensing position of the first sensing element 222, the moving module 13 can rise, and the rest of the casting equipment is in a locked state to prevent the movement of other components from affecting the mold closing; the second detection position: the sensing block 214 displays the mold closing position in real time and accurately controls the mold closing position; the second sensing element is a split displacement sensor (the sensing block 214 installed on the extension rod 213 and the sensing base 215 in the mounting groove 221 respectively, which can display the position in real time).

[0050] As shown in FIG2 , the first sensing element 222 and the third sensing element 223 are position sensors.

[0051] In the working state, the position sensor is used to detect the position of the moving module 13, so as to ensure that when the sensing block 214 moves to the second detection position and the third detection position, it can promptly send a control instruction to the lifting device 16 to adjust the lifting speed of the moving module 13.

[0052] As shown in FIG5 , a sealing rubber ring 17 is embedded in the surface of the mold plate cover 12 that contacts the casting chamber 11 .

[0053] The sealing ring is used to further seal the contact surface between the mold plate cover 12 and the casting chamber 11 when the mold plate cover 12 is locked by the mold locking mechanism 3 , thereby maintaining a good sealing effect in the casting chamber 11 .

[0054] 4 and 5 : the clamping mechanism 3 is provided with an actuator arm 31 coaxially fixed at the shaft head of the flip bracket 14 and a linear drive 32 for driving the axis of the actuator arm 31 to flip circumferentially along the flip axis of the flip bracket 14, and the linear drive 32 has a circumferential fixing element 33 for pre-locking the driving formation of the linear drive 32 before the driving state.

[0055] In the working state, the actuator arm 31 consists of a driving main arm and an arc arm fixedly arranged at the end of the driving main arm; the driving end of the linear drive 32 is hinged to the arc arm through a pin shaft. By adopting the design of adding an arc arm at the end of the driving main arm, the flip angle can be increased when driving the flip bracket 14 to flip; when the mold cover 12 needs to be locked, the output shaft of the linear drive 32 extends 7-8mm from the minimum stroke and is locked by the circumferential fixing element 33, and then the actuator arm 31 is locked with the flip bracket 14, thereby converting the linear driving force of the linear drive 32 into a flipping force for the mold cover 12; when the driving end of the linear drive 32 contracts to the minimum stroke, this reserved 7-8mm stroke is converted into a downward pressure on the mold cover 12, thereby pressing the sealing ring to achieve the effect of locking the mold cover 12, thereby effectively improving the sealing performance of the mold cover 12.

[0056] 4 and 5 : the linear drive 32 includes a mounting panel 321 , a circumferential fixing element 33 , an electric push rod 322 and a hinge portion 323 ;

[0057] The non-working end of the electric push rod 322 is fixed to one side of the mounting panel 321 through a hinge portion 323 , and the telescopic rod of the electric push rod 322 is hinged to the actuator arm 31 through a pin shaft;

[0058] The circumferential fixing element 33 is coaxially fixedly arranged at the connection between the actuator arm 31 and the shaft head of the flip bracket 14 .

[0059] In the working state, the telescopic rod of the electric push rod 322 extends 7-8mm from the minimum stroke position and is locked by the circumferential fixing element 33; when it is necessary to drive the mold plate cover 12 to flip, close and open, it is only necessary to connect an external power supply to drive the electric push rod 322 to work, and the telescopic rod of the electric push rod 322 extends to drive the actuator arm 31 to move, and the actuator arm 31 synchronously drives the flip bracket 14 to flip under the action, thereby achieving the effect of driving the mold plate cover 12 to open and close.

[0060] 4 and 5 , the circumferential fixing element 33 is a hydraulic locking sleeve.

[0061] The hydraulic locking sleeve is a prior art and will not be described in detail here. It is used to lock the reserved stroke of the electric push rod 322.

[0062] The present application can not only achieve efficient and precise mold clamping of the movable module 13 and the casting unit 1 , but also achieve sealing of the fitting surface on the casting chamber 11 covered by the mold cover plate.

[0063] The above embodiments merely represent one or several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
