[0024] Embodiment Two

[0025] Please refer to Figures 4 - 6, on the basis of the first embodiment, the forming equipment based on the production of aerated concrete blocks in this embodiment is added with an intelligent temperature control component. The intelligent temperature control component includes a temperature induction probe 14 and a controller 15. The temperature induction probe 14 is fixedly installed inside the curing box 1, and the controller 15 is fixedly connected to the other side of the curing box 1. The input end of the controller 15 is signal-connected to the output end of the temperature induction probe 14, and the output end of the controller 15 is electrically connected to the input end of the heating plate 3. The controller 15 includes a signal receiving module 151, a signal processing module 152, a numerical setting module 153, and a circuit control module 154. The input end of the signal receiving module 151 is signal-connected to the output end of the temperature induction probe 14, and the output end of the signal receiving module 151 is signal-connected to the input end of the signal processing module 152. The output end of the signal processing module 152 is signal-connected to the input end of the numerical setting module 153. The output end of the numerical setting module 153 is signal-connected to the input end of the circuit control module 154. The output end of the circuit control module 154 is electrically connected to the input end of the heating plate 3; In this embodiment, when the slurry inside the curing box 1 is heated and cured into shape, the temperature induction probe 14 will detect the temperature inside the curing box 1 in real time and transmit the detected temperature value to the signal receiving module 151 in the form of a signal. The signal receiving module 151 will transmit the received signal to the signal processing module 152, and the signal processing module 152 will amplify and analyze the signal and transmit the processed signal to the numerical setting module 153. If the temperature value detected by the temperature induction probe 14 is less than the temperature value range set by the numerical setting module 153, the circuit control module 154 will turn on the circuit of the heating plate 3, so that the heating plate 3 generates heat due to being powered on. If the temperature value detected by the temperature induction probe 14 is greater than the temperature value range set by the numerical setting module 153, the circuit control module 154 will disconnect the circuit of the heating plate 3, so that the heating plate 3 stops generating heat due to being powered off. In this way, the temperature inside the curing box 1 can be controlled in a suitable curing environment, so that the slurry can better generate gas to form a blank, thus facilitating the intelligent control of the curing and forming temperature of the aerated concrete block.

[0026] To sum up, for the forming equipment based on the production of aerated concrete blocks in this embodiment, by setting the temperature induction probe 14 and the controller 15, it is convenient to accurately control the temperature inside the curing box 1 during the curing and forming process of the aerated concrete block, so that the slurry can better generate gas to form a blank in a suitable curing environment, thus reflecting the intelligence of the forming equipment.

[0027] Working principle and usage process of the present invention: First, push the mold frame with the slurry mold to one side of the curing box 1, then use the steering component 4 to rotate the top cover 2 to directly above the mold frame, and start the electric push rod 7 to make it extend. The electric push rod 7 will drive the mounting sleeve 9 to move vertically downward, so that the mounting sleeve 9 is sleeved outside the top of the screw rod 11, and use bolts to fix the two; Then start the electro-hydraulic rod 5 to make it extend. The electro-hydraulic rod 5 will drive the top cover 2 and the mold frame fixed to its bottom to move vertically upward through the cross plate 6 until the moving seat 10 at the bottom of the mold frame is higher than the top of the curing box 1. Then use the steering component 4 to rotate the mold frame to directly above the top of the curing box 1. At this time, start the electro-hydraulic rod 5 again to make it retract. The electro-hydraulic rod 5 will drive the top cover 2 and the mold frame fixed to its bottom to move vertically downward through the cross plate 6, so that the top cover 2 is sleeved outside the top of the curing box 1, and the mold frame is located inside the curing box 1, which is convenient to put the mold frame into the curing box 1. On the contrary, after curing, the mold frame can be taken out from the inside of the curing box 1; Immediately start the electric push rod 7 to make it extend, so that the mold frame moves vertically downward inside the curing box 1, causing the universal wheels of the moving seat 10 at the bottom of the mold frame to contact the bottom of the inner cavity of the curing box 1. Then connect the circuit of the heating plate 3, so that the heating plate 3 generates heat due to being powered on. At the same time, turn on the rotary motor 82, so that the mold frame rotates slowly inside the curing box 1. This can make the slurry inside the mold on the mold frame fully heated, so that the slurry can better generate gas to form a green body; Finally, the temperature induction probe 14 will detect the temperature inside the curing box 1 in real time, and transmit the detected temperature value to the signal receiving module 151 in the form of a signal. The signal receiving module 151 will transmit the received signal to the signal processing module 152, and the signal processing module 152 will amplify and analyze the signal, and transmit the processed signal to the numerical setting module 153. If the temperature value detected by the temperature induction probe 14 is less than the temperature value range set by the numerical setting module 153, the circuit control module 154 will connect the circuit of the heating plate 3, so that the heating plate 3 generates heat due to being powered on. If the temperature value detected by the temperature induction probe 14 is greater than the temperature value range set by the numerical setting module 153, the circuit control module 154 will disconnect the circuit of the heating plate 3, so that the heating plate 3 stops generating heat due to being powered off. This can control the temperature inside the curing box 1 in a suitable curing environment, so that the slurry can better generate gas to form a green body, thus facilitating the intelligent control of the curing and forming temperature of the aerated concrete block.
