In the working state, the movable module 13 is lifted and moved upwards at a higher speed under the lifting of the oil cylinder of the lifting device 16, the movable detection unit 21 is synchronously driven to lift while the movable module 13 is lifted, when the movable unit is close to the fixed detection unit 22 vertically arranged on the equipment rack in the continuous lifting process, the fixed detection unit 22 detects the movable detection unit 21, namely the first detection position, in the lifting process, the movable detection unit 21 continuously moves upwards, the fixed detection unit 22 sends an early warning signal to the system, the movable detection unit 13 can lift, and other casting equipment is in a locking state; when the movable detection unit 21 continues to move upwards and moves upwards to the second detection position, the fixed detection unit 22 sends a control signal to the lifting device 16 to drive the lifting device to decelerate and lift in a deceleration state; when the movable detecting unit 21 continues to move upwards and moves upwards to the third detecting position, the fixed detecting unit 22 sends out a deceleration signal to the lifting device 16 again and drives the lifting device to rise at an extremely slow speed; until the movable module 13 and the die assembly surface of the casting chamber 11 are closed, the movable module 13 is controlled to be lifted in a staged mode, so that the die assembly efficiency can be effectively maintained, the stability of die assembly is ensured, and the phenomenon of liquid leakage caused by die collision and out-of-place die assembly due to too high die assembly speed is avoided.
See fig. 2, 3, 6 and 7: the activity detection unit 21 includes a fixed loop bar 211, an adjustment bar 212, an extension bar 213, and a second sensing element; the fixed sleeve 211 is vertically and fixedly arranged on one side of the movable module 13 through a fixed bottom plate; the adjusting lever 212 is slidably disposed in the fixed sleeve 211 and is disposed toward the outside through an end of the fixed sleeve 211; the extension rod 213 is vertically arranged at the end of the adjusting rod 212 in a vertical state, and the rod end of the extension rod 213 extends towards the ground; the second sensing element is a split displacement sensor, and consists of a sensing block 214 and a sensing base 215, so that the position can be displayed in real time; the sensing block 214 of the second sensing element is fixedly arranged at the end of the extension rod 213.
Under the operating condition, since the adjusting rod 212 is slidably disposed in the fixed sleeve 211, the adjusting rod 212 can be flexibly adjusted according to the detection requirement and the installation position of the movable detection unit 21, so that the sensing block 214 can be in contact with the fixed detection unit 22 to the greatest extent, thereby presenting a more sensitive and accurate detection effect.
The sensing block 214 is used to cooperate with the fixed detection unit 22; the lifting position of the movable module 13 is provided for the fixed detection unit 22 in real time, so that the precise control of the lifting height of the movable module 13 is realized.
See fig. 2, 3, 6 and 7: the fixed sensing unit 22 includes a mounting groove 221, a first sensing element 222, a sensing base 215, a third sensing element 223, and an adjustment plate 224; the first sensing element 222, the sensing base 215 and the third sensing element 223 are movably arranged on one side of the installation groove 221, which is close to the movable detection unit 21, through the adjusting plate 224, and the first sensing element 222, the sensing base 215 and the third sensing element 223 are respectively arranged near the upper, middle and lower three positions of the installation groove 221; thereby forming the first, second and third detection bits, respectively.
In the working state, when the movable module 13 moves vertically upwards under the driving of the lifting device 16, the movable detection unit 21 fixedly arranged on one side of the movable module 13 is synchronously driven to move upwards, and when the movable module 13 moves to the first sensing element 222, the first sensing element 222 gives early warning to the system, the movable module 13 can be lifted, and other casting equipment are all in a locking state; after being detected by the sensing base 215, the sensing block 214 transmits a control signal to the lifting device 16, so that the lifting device 16 is driven to execute a corresponding deceleration instruction, the lifting speed of the lifting device 16 is flexibly controlled, and the movable module 13 can accurately reach the die closing position each time through the comparison of two groups of second sensing element data; since the first sensor 222, the sensing base 215 and the third sensor 223 are all fixedly disposed on one side of the mounting groove 221 through the adjusting plate 224, when the detection point is required to be adjusted, the change of the mounting positions of the first sensor 222, the sensing base 215 and the third sensor 223 can be realized through the sliding adjustment of the adjusting plate 224; first detection bit: the first sensing element 222 senses that the removal module 13 can ascend, and other casting equipment is in a locking state, so that the other parts are prevented from moving to influence the die assembly; second detection bit: the sensing block 214 displays the die closing position in real time and precisely controls the die closing position; the second sensor element is a split displacement sensor (a sensing block 214 respectively installed on the extension rod 213 and a sensing base 215 in the installation groove 221, and the positions can be displayed in real time).

See fig. 5: the surface of the mold disc cover 12, which is attached to the casting chamber 11, is also provided with a sealing rubber ring 17 in an embedded manner.
The sealing ring is used for realizing the further sealing of the joint surface of the mold disc cover 12 and the casting chamber 11 when the mold disc cover 12 is driven by the mold locking mechanism 3 to lock the mold; thereby maintaining a good sealing effect in the casting chamber 11.
See fig. 4 and 5: the mold locking mechanism 3 is provided with an actuating arm 31 coaxially and fixedly arranged at the shaft head of the turnover support 14 and a linear driver 32 for driving the axis of the actuating arm 31 to circumferentially turn along the turnover axis of the turnover support 14, and the linear driver 32 is provided with a circumferential fixing element 33 for pre-locking the driving formation of the linear driver 32 before the driving state.

In the working state, the reserved travel of the telescopic rod of the electric push rod 322, which extends out of the minimum stroke by 7-8mm, is locked by the circumferential fixing element 33; when the mold cover 12 needs to be driven to turn over, cover and open, only an external power supply is connected to drive the electric push rod 322 to work, the telescopic rod of the electric push rod 322 extends to drive the actuating arm 31 to act, and the actuating arm 31 synchronously drives the turning support 14 to turn over under the action, so that the effect of driving the mold cover 12 to open and close is achieved.
