[0027] A modular prefabricated concrete casting template working principle: During the modular molding of the prefabricated concrete casting, the first electric push rod 103 is first controlled to start and drive the main bevel gear 104 to move forward to the meshing part of the two sets of auxiliary bevel gears 105, and then the double-headed motor 101 is controlled to start and drive the meshed main bevel gear 104 and the two sets of auxiliary bevel gears 105 to rotate in opposite directions through the short rotating shaft 102. The two sets of auxiliary bevel gears 105 drive the two threaded short rods 106 to rotate accordingly, and the two threaded short rods 106 drive the two sets of threaded sleeves 107 to move inward synchronously, and the two sets of threaded sleeves 107 drive the two sets of push seats 108 to rotate accordingly. While moving inward, the two groups of short light rods 15, the sliding sleeves 16 and the buffer springs 17 cooperate with the sliding support of the two groups of push seats 108, and the rolling support of the two groups of guide rail frames 18, the support frames 19 and the guide wheels 20, so that the two groups of push seats 108 synchronously drive the long wall panels 3 and the short wall panels 4 to move toward the base plate 1 and the rear wall panel 7, until the long wall panels 3 and the short wall panels 4 are spliced ​​with the base plate 1 and the rear wall panel 7, first control the double-headed motor 101 to pause, and then control the first electric push rod 103 to close and drive the main bevel gear 104 to move backward to disengage the meshing part of the two groups of auxiliary bevel gears 105 to the initial position; Next, the two second electric push rods 113 are controlled to open and drive the two sets of secondary circular gears 112 to move backward to the meshing part of the main circular gear 111, and then the double-headed motor 101 is controlled to open again and drive the two sets of secondary circular gears 112 to rotate through the meshing main circular gear 111, and the two sets of secondary circular gears 112 drive the two threaded long rods 114 to rotate accordingly, and the two threaded long rods 114 drive the two threaded long tubes 115 to move backward synchronously, and the long light rod 118 that follows the movement plays a sliding support role between the push plate 116 and the base frame 2, and the slide rail frame 21, the inner skeleton 22 and the slide rail wheel 23 cooperate with the rolling support of the inner mold 9, so that the two threaded long tubes 115 can move backward synchronously. The long tube 115 drives the inner mold 9 on the two pushing rods 117 to move toward the base plate 1 through the pushing plate 116 until the inner mold 9 reaches the correct position of the long wall panel 3 and the short wall panel 4 spliced ​​in place with the base plate 1 and the rear wall panel 7, firstly controls the double-headed motor 101 to pause, then controls the two second electric push rods 113 to close and drives the two sets of secondary circular gears 112 to move forward and disengage from the meshing part of the main circular gear 111 to the initial position, and then tightens and fixes the long wall panel 3 and the short wall panel 4 spliced ​​in place with a plurality of wall clamping rods 26, so that the overall splicing work of the base plate 1, the rear wall panel 7, the long wall panel 3, the short wall panel 4 and the inner mold 9 before casting is completed; Then, first control the third electric push rod 123 to open and drive the driven bevel gear 122 to move down and get stuck in the meshing part of the driving bevel gear 121, then control the double-headed motor 101 to turn on again and drive the driven bevel gear 122 to rotate through the meshed driving bevel gear 121, and the driven bevel gear 122 drives the planetary bevel gear 125 on the long rotating shaft 124 to rotate accordingly, and while the long wall panel 3 and the short wall panel 4 are spliced ​​into place toward the base plate 1 and the rear wall panel 7, the two bevel gear racks 126 are driven to move inward synchronously through the two sets of side frames 5 thereon to get stuck in the meshing part of the planetary bevel gear 125, and the planetary bevel gear 125 drives the two meshed bevel gear racks 126 to rotate, and the other end gears of the two bevel gear racks 126 drive the two sets of differential bevel gears 131 to rotate accordingly, and the two sets of differential bevel gears 131 drive the two sets of differential bevel gears 131 through the two long rotating rods 132 The cam frame 133 rotates, and when the outermost ends of the two groups of cam frames 133 rotate to the head end positions of the two groups of push rod frames 134, the two groups of push rod frames 134 drive the two groups of vibration seats 136 and buffer pads 24 to knock towards the long wall panels 3 and the short wall panels 4, and compress the two groups of return springs 135. At this time, the two groups of vibration seats 136 and buffer pads 24 in the knocking state vibrate the casting area between the long wall panels 3 and the short wall panels 4 and the inner mold 9. When the innermost ends of the two groups of cam frames 133 rotate to the head end positions of the two groups of push rod frames 134, the two groups of push rod frames 134 that have lost the extrusion force drive the two groups of vibration seats 136 and buffer pads 24 away from the long wall panels 3 and the short wall panels 4 under the elastic return action of the two groups of return springs 135, and reciprocate in this way to continuously vibrate the casting area between the long wall panels 3 and the short wall panels 4 and the inner mold 9; At the same time, the long rotating shaft 124 drives the worm 141 to rotate synchronously with the planetary bevel gear 125, and the worm 141 drives the two sets of worm wheels 142 to rotate accordingly, and the two sets of worm wheels 142 drive the two reciprocating screws 143 to rotate accordingly, and the two reciprocating screws 143 drive the two sets of screw sleeves 144 to move back and forth horizontally, and the two sets of screw sleeves 144 drive the hopper 27 through the two sets of connecting seats 145 to move between the base plate 1, the rear wall panel 7, and the long wall panel 3 that are spliced ​​in place. , short wallboard 4 and inner mold 9 casting area are horizontally displaced back and forth, and the materials prepared in advance in the hopper 27 are distributed to the two sets of distribution pipes 147 through the two sets of four-way valves 146, and then uniformly and comprehensively distributed by two rows of distribution heads 148 to the casting areas of the base plate 1, rear wallboard 7, long wallboard 3, short wallboard 4 and inner mold 9 that are spliced ​​in place, and then combined with the two sets of vibration seats 136 and buffer pads 24 to continuously align the long wallboard 3 and the short wallboard 4 with the inner mold 9. Under the action of continuous vibration force in the casting area between the molds 9, the material is forced to be evenly distributed in the casting area, and the material level in the hopper 27 is monitored in real time by the material level sensor 28, and replenished in time until the material is distributed. After the material is left to stand for a predetermined time, the precast concrete castings in the casting area of ​​the base plate 1, the rear wall panel 7, the long wall panel 3, the short wall panel 4 and the inner mold 9 are formed. On the contrary, the double-headed motor 101 is first controlled to pause, and then the third electric push rod 123 is controlled to be closed and drive the driven bevel gear 122 to move up and disengage from the meshing part of the driving bevel gear 121 to the initial position, stop the knocking vibration of the two sets of vibration seats 136 and the back and forth feeding work of the hopper 27, and then successively separate and reset the long wall panel 3 and the short wall panel 4 from the inner mold 9 from the base plate 1 and the rear wall panel 7, and then demold and remove the formed precast concrete castings, and so on, the modular production of several precast concrete castings can be realized.

[0028] It should be noted that the specific models and specifications of the double-headed motor 101, the electric push rod and the material level sensor 28 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0029] The power supply circuits of the double-headed motor 101, the electric push rod and the material level sensor 28 are clear to those skilled in the art and will not be described in detail here.
