One ends of two first connecting rods 305 are respectively hinged to the two vertical plates 4051.

During the downward movement of the longitudinal moving pressing plate 4071, the limit slider 403 is pushed towards the side of the bottom case 101, so as to push the installation groove 302 downward through the first connecting rod 305, enabling the supporting block 309 to enter the side groove 104. When the longitudinal moving pressing plate 4071 continues to move downward, the clamping rod 4064 is pushed into the clamping groove 102. Installation is achieved by the downward movement of the longitudinal moving pressing plate 4071, which is convenient for use. When the positioning rod 4078 is clamped with the upper positioning groove 4053, the bottom case 101 and the top cover 201 are in a separated state, and the supporting block 309 is completely located inside the communication groove 306.

When the positioning rod 4078 is clamped with the lower positioning groove 4055, the bottom case 101 and the top cover 201 are in a clamped state, and the supporting block 309 enters the side groove 104, thus facilitating the determination of the three states and facilitating the forming and blanking of the perforated bricks.

[0041] The moving limiting unit 408 includes a lower longitudinal limiting plate 4081 fixedly installed at the top end of the top cover 201. A middle inclined limiting plate 4082 is fixedly installed at the top end of the lower longitudinal limiting plate 4081.

The bottom end of the middle inclined limiting plate 4082 is inclined towards the side of the bottom case 101. During the downward movement of the longitudinal moving pressing plate 4071, the limit slider 403 is pushed towards the side of the bottom case 101, so as to push the installation groove 302 downward through the first connecting rod 305, enabling the supporting block 309 to enter the side groove 104. When the longitudinal moving pressing plate 4071 continues to move downward, the clamping rod 4064 is pushed into the clamping groove 102. Installation is achieved by the downward movement of the longitudinal moving pressing plate 4071, which is convenient for use.

[0042] Working principle: During operation, first install the top cover 201 at the top of the bottom shell 101, so that the respective insertion rods 204 at the bottom end of the top cover 201 are inserted into the respective slots 103. At this time, the limiting rod 4072 contacts the side wall of the upper longitudinal limiting plate 4083. Then, pinch the two push plates 4079 at the top ends of the two longitudinal moving pressing plates 4071, so that the two positioning rods 4078 approach each other and disengage from the upper positioning groove 4053, and push the longitudinal moving pressing plate 4071 downward, so that the limiting rod 4072 moves downward along the inclined surface of the middle inclined limiting plate 4082, causing the two longitudinal moving pressing plates 4071 to approach each other, thereby pushing the two vertical plates 4051 to approach each other, and then pushing the mounting plate 303 downward, so that the push rod 304 moves downward to push the movable plate 310 downward, and then through the respective second connecting rods 311, push the respective supporting blocks 309 into the respective side slots 104. At this time, the two positioning rods 4078 on the longitudinal moving slider 4074 move to positions corresponding to the middle positioning groove 4054;

[0043] Then continue to push the longitudinal moving pressing plate 4071 downward, so that the limiting rod 4072 at the bottom end of the longitudinal moving pressing plate 4071 generates pressure on the wedge block 4067, pushing the clamping rod 4064 to move toward one side of the bottom shell 101, so that the clamping rod 4064 is clamped into the clamping groove 102, and the top cover 201 is clamped and fixed to the bottom shell 101. At this time, the positioning rod 4078 moves downward to a position corresponding to the lower positioning groove 4055, release the two push plates 4079, and under the elastic force of the connecting spring 40710, the positioning rod 4078 is clamped into the lower positioning groove 4055 to fix the longitudinal moving pressing plate 4071;

[0044] Subsequently, unscrew the pipe plug 203 to open the feed pipe 202, and introduce the raw material into the forming cavity from the feed pipe 202. Since the insertion rods 204 are uniformly arranged inside the forming cavity, after forming, pores appear on the bricks;

[0045] After forming, for discharging, pinch the two push plates 4079 at the top ends of the two longitudinal moving pressing plates 4071, so that the positioning rod 4078 disengages from the lower positioning groove 4055, and then pull the longitudinal moving pressing plate 4071 upward until the positioning rod 4078 is in a state corresponding to the middle positioning groove 4054, so that the positioning rod 4078 is clamped into the middle positioning groove 4054. At this time, the limiting slider 403 is still pressed tightly, so that the supporting block 309 still remains inside the side slot 104, but the clamping rod 4064 moves back under the elastic force of the pressing spring 4065 and disengages from the clamping groove 102, so that the bottom shell 101 is separated from the top cover 201. Then pull the top cover 201 upward. Since the supporting block 309 is located below the porous brick at this time, the porous brick is taken out from the bottom shell 101;

[0046] After taking out, pinch the two push plates 4079 at the top ends of the two longitudinal moving pressure plates 4071, so that the positioning rod 4078 is disengaged from the middle positioning groove 4054, and then pull the longitudinal moving pressure plate 4071 upward until the positioning rod 4078 corresponds to the upper positioning groove 4053, so that the positioning rod 4078 is engaged with the upper positioning groove 4053. At this time, the limit slider 403 moves outward under the elastic force of the compression spring 404, so as to pull the mounting plate 303 upward through the first connecting rod 305, making the push rod 304 move upward. At this time, the movable plate 310 moves upward under the elastic force of the return spring 313, and pulls each supporting block 309 back into the communication groove 306 through the second connecting rod 311, pulling the top cover 201 upward and pulling out the insertion rod 204 from the holes of the perforated brick, which is convenient for blanking.
