[0029] The injection molding machine body 110 includes an air induced draft box 121 fixedly installed at both ends of the injection molding machine body 110, and a double-axis stepping synchronous motor 122 is installed inside the two sets of air induced draft boxes 121. The outer wall of the output shaft of the double-axis stepping synchronous motor 122 is sleeved with a transmission belt 123. A fan blade 124 connected to the transmission belt 123 is provided at the air inlet of one end of the air induced draft box 121 through a connecting shaft, and a rotating disk 125 is connected to the other end of the inner wall of the transmission belt 123 through a connecting shaft. A limited stroke groove 126 is installed at one end of the rotating disk 125, and two sets of connecting plates 127 are respectively installed at both ends of the limited stroke groove 126. A pushing block 128 is installed at the other end of each set of connecting plates 127. A fixed block 129 is fixedly installed on one side of the inner wall of the air induced draft box 121 close to the pushing block 128, and a push rod 1291 is provided inside the fixed block 129 for sliding. A first telescopic spring 1292 is sleeved on the outer wall of the push rod 1291, and a filter dust removal net 1293 is provided on one end of the inner wall of the draft box 121 close to the push rod 1291. The rear end of the filter dust removal net 1293 is located on the inner wall of the draft box 121 and is fixedly installed with four groups of second telescopic springs 1294. A first connecting block 1295 that penetrates and extends to the bottom end of the draft box 121 is installed at one end of the frame edge of the filter dust removal net 1293. The bottom end of the draft box 121 is located below the first connecting block 1295 and is provided with a dust box 1296. A detachable dust bag 1298 that is connected to the dust box 1296 is provided at the bottom of the dust box 1296.

[0030] When cleaning the dust attached to the inside of the filter dust removal net 1293 and cooling the injection molding machine body 110, the dual-axis stepping synchronous motor 122 is started, thereby prompting the transmission belt 123 to rotate the fan blades 124 and the rotating disk 125, thereby driving the two sets of connecting plates 127 to slide along the limit stroke groove 126 and the limit block on both sides, prompting the pushing block 128 installed at the end of the connecting plate 127 to contact the push rod 1291, thereby compressing the first telescopic spring 1292 to prompt The other end of the push rod 1291 contacts and collides with the filter dust removal net 1293, and at the same time, the second telescopic spring 1294 at the edge of the frame at the other end of the filter dust removal net 1293 pushes the filter dust removal net 1293, so that the filter dust removal net 1293 is always in contact with one end of the push rod 1291, thereby achieving a vibration effect on the filter dust removal net 1293. When the filter dust removal net 1293 vibrates, the dust attached to the inner wall of the filter dust removal net 1293 falls off, and at the same time, the filter dust removal net 1293 During the reciprocating vibration process, 1293 causes one end of the first connecting block 1295 connected to the dust box 1296 to slide, causing negative air pressure to be formed in the dust box 1296. At the same time, the one-way valve in the connecting pipe 147 is closed, and the one-way valve in the dust pipe 1297 is opened, causing the dust on the filter dust net 1293 to fall and pass through the dust pipe 1297 and be sucked into the dust box 1296. At the same time, when the first connecting block 1295 slides to the right, the one-way valve in the dust pipe 1297 is opened. When the connecting pipe 147 is closed, the one-way valve in the connecting pipe 147 is opened, so that the dust can be sucked into the detachable dust bag 1298 wrapped with the strap on the outer wall of the connecting pipe 147, thereby achieving self-cleaning of the dust in the filter dust removal net 1293 and preventing dust from overflowing. The detachable dust bag 1298 can be disassembled and cleaned for recycling, and the electronic components 150 in the induced draft box 121 can be dissipated sustainably, and the workpieces in the workpiece placement slot 130 can be air-cooled through the air supply pipe 131.

[0031] Please refer to Figure 1 and Figure 4 The cooling spray assembly 140 includes a water-cooled box 141 fixedly mounted on the upper end of the base plate 100 near the side of the induced draft box 121, a mounting limit seat 142 is installed at the bottom end of the induced draft box 121, and a cooling pipe 143 is provided on the upper end of the mounting limit seat 142, which penetrates the induced draft box 121 and extends into the water-cooled box 141. A connecting pipe 147 is installed at the other end of the cooling pipe 143, and the connecting pipe 147 is located above the workpiece placement trough 130. Three groups of equidistant circumferentially distributed transmission rods 144 are installed on the output shaft at the other end of the dual-axis stepping synchronous motor 122, and a rolling extrusion cylinder 145 is rotatably installed between each group of transmission rods 144. A reflux pipe 146 connected to the water-cooled box 141 is installed at the bottom end of the workpiece placement trough 130.

[0032] When the workpiece in the workpiece placement slot 130 is subjected to a cooling treatment, when the dual-axis stepping synchronous motor 122 rotates, the other end of the dual-axis stepping synchronous motor 122 penetrates the middle of the filter dust removal net 1293 and extends to the transmission rod 144 connected to the bearing inside the induced draft box 121 to rotate, so that the rolling extrusion cylinder 145 rotatably installed between the three groups of transmission rods 144 cyclically rolls the cooling pipe 143 placed in the limit seat 142 installed below, so that the cooling pipe 143 forms a negative pressure, and then the other end of the cooling pipe 143 is cooled. The cooling water in the water-cooling box 141 connected to the end is sprayed on the workpiece in the workpiece placement trough 130 through the atomizing nozzle installed at the end of the connecting pipe 147, so as to cool the workpiece placed in the workpiece placement trough 130, and the sprayed cooling water can be collected through the return pipe 146 connected between one end of the workpiece placement trough 130 and the water-cooling box 141, and then flow into the water-cooling box 141 for cooling, so as to quickly cool the workpiece, speed up the processing speed of the product, and avoid the waste of water resources.

[0033] Please refer to Figure 2 and Figure 3 Brackets are installed at both inner and outer ends of the air inlet at one end of the induced draft box 121, and one end of the fan blade 124 and the rotating disk 125 are fixedly installed at both ends of the inner part of the bracket through a transmission shaft.

[0034] The fan blades 124 and the rotating disk 125 rotate through the transmission shafts fixedly installed at both ends of the bracket.

[0035] Please refer to Figure 2 and Figure 3 A sliding groove for sliding the first connecting block 1295 is provided at the bottom of the inner wall of the induced draft box 121, and a positioning rod is provided in the sliding groove, which passes through the first connecting block 1295 and extends to both ends of the sliding groove.

[0036] The first connecting block 1295 can slide to the left and right sides in the sliding groove through the positioning rod.

[0038] The cooling pipe 143 is connected to the water cooling box 141 via one end to cool the workpiece in the workpiece placement tank 130 by passing cooling water through an atomizing nozzle.

[0039] Please refer to Figure 5 and Figure 6A one-way valve is provided inside the dust box 1296 at the connection position with the dust pipe 1297, a dust outlet pipe is installed at the bottom end of the dust box 1296, a detachable dust bag 1298 is fixed to the outer wall of the dust outlet pipe by wrapping with a strap, and a one-way valve is installed at the connection position with the dust outlet pipe at the bottom end of the dust box 1296.

[0040] A pushing plate connected to the first connecting block 1295 is provided in the dust box 1296 , and the size of the pushing plate matches the size of the inner wall of the dust box 1296 .

[0041] Please refer to Figure 2 and Figure 3 Two groups of limit blocks are installed on the inner wall of the induced draft box 121 near the two sides of the rotating disk 125, and each group of limit blocks is provided with a travel groove for the connecting plate 127 to slide.

[0042] The connecting plate 127 can slide on both sides along the travel groove provided in the limiting block.

[0043] When in use, when cleaning the dust attached to the inside of the filter dust removal net 1293 and cooling the injection molding machine body 110, the dual-axis stepping synchronous motor 122 is started, thereby prompting the transmission belt 123 to rotate the fan blades 124 and the rotating disk 125, thereby driving the two sets of connecting plates 127 to slide along the limit stroke groove 126 and the limit block on both sides, prompting the pushing block 128 installed at the end of the connecting plate 127 to contact the push rod 1291, thereby compressing the first telescopic spring 1292. The second retractable spring 1294 at the edge of the frame at the other end of the filter dust removal net 1293 pushes the filter dust removal net 1293, so that the filter dust removal net 1293 is always in contact with one end of the push rod 1291, thereby achieving a vibration effect on the filter dust removal net 1293. When the filter dust removal net 1293 vibrates, the dust attached to the inner wall of the filter dust removal net 1293 falls off, and the filter dust removal net 1293 is also moved. The dust net 1293 causes one end of the dust net 1293 connected to the first connecting block 1295 to slide inside the dust box 1296 during the reciprocating vibration process, causing negative air pressure to be formed in the dust box 1296. At the same time, the one-way valve in the connecting pipe 147 is closed, and the one-way valve in the dust pipe 1297 is opened, causing the dust on the dust filter 1293 to fall and pass through the dust pipe 1297 and be sucked into the dust box 1296. At the same time, when the first connecting block 1295 slides to the right, the one-way valve in the dust pipe 1297 is opened. The valve is closed, and the one-way valve in the connecting pipe 147 is opened, so that the dust can be sucked into the detachable dust bag 1298 wrapped with the strap on the outer wall of the connecting pipe 147, so as to achieve self-cleaning of the dust in the filter dust removal net 1293 and prevent dust from overflowing. The detachable dust bag 1298 can be disassembled and cleaned for recycling, and the electronic components 150 in the induced draft box 121 can be dissipated sustainably, and the workpieces in the workpiece placement slot 130 can be air-cooled through the air supply pipe 131.

[0044] When the workpiece in the workpiece placement slot 130 is subjected to a cooling treatment, when the dual-axis stepping synchronous motor 122 rotates, the other end of the dual-axis stepping synchronous motor 122 penetrates the middle of the filter dust removal net 1293 and extends to the transmission rod 144 connected to the bearing inside the induced draft box 121 to rotate, so that the rolling extrusion cylinder 145 rotatably installed between the three groups of transmission rods 144 cyclically rolls the cooling pipe 143 placed in the limit seat 142 installed below, so that the cooling pipe 143 forms a negative pressure, and then the other end of the cooling pipe 143 is connected to the cooling water in the water cooling box 141 through The atomizing nozzle installed at the end of the connecting pipe 147 sprays water-cooling on the workpiece in the workpiece placement trough 130, thereby achieving the cooling treatment of the workpiece placed in the workpiece placement trough 130, and the return pipe 146 connected between one end of the workpiece placement trough 130 and the water cooling box 141 can collect the sprayed cooling water and flow it to the inside of the water cooling box 141 for cooling again, thereby achieving rapid cooling of the workpiece, accelerating the processing speed of the product, and avoiding the waste of water resources.
