[0042] Embodiment three:

[0043] Reference Figure 2 as well as Figure 4-Figure 8 , which is basically the same as Example 2, and further discloses a specific implementation plan for demoulding the injection molded parts.

[0045] During operation, the lower mold 4 after injection molding is conveyed by the conveyor belt to the top of the ejector rod 19. At this time, the next lower mold 4 is conveyed by the conveyor belt to the bottom of the upper mold 5. Therefore, when demoulding, the next lower mold 4 is performing mold closing injection molding, thereby enabling continuous production and improving production efficiency. When demoulding, the positioning plate 7 rises to drive the mounting frame 17 to rise. The mounting frame 17 drives the ejector rod 19 to rise through the connecting plate 18 to eject the injection molded part in the lower mold 4 out of the lower mold 4. At the same time, the rotation of the screw rod 302 will drive the transmission through the second belt drive 25. The movable shaft 23 rotates, and the transmission shaft 23 drives the cam 24 to rotate. The cam 24 squeezes the connecting plate 18 to drive the connecting plate 18 to rise, and the connecting plate 18 drives the ejector rod 19 and the connecting block 20 to rise. The connecting block 20 slides upward along the guide rod 21 and compresses the first spring 22. Then the first spring 22 is reset, so that the connecting plate 18 drives the ejector rod 19 to vibrate longitudinally. The ejector rod 19 vibrates the lower mold 4 while ejecting the injection molded part, which is conducive to better detachment of the injection molded part from the lower mold 4 and improves the demoulding efficiency.

In the initial state, the second spring 33 is at the free end, and the upper half of the T-plate 31 is against the inner wall of the T-slot 30, so that the T-slot 30 is avoided. When the ejector rod 19 is pushed upward out of the T-plate 31, the T-plate 31 slides upward along the T-slot 30. At this time, the gas generated by the air intake device 26 can enter the T-slot 30, thereby blowing toward the injection molded part for better demoulding. A conveyor belt is installed on the housing 16, and the conveyor belt is arranged above the conveyor belt. After the injection molded part is demoulded, the robot removes the injection molded part and puts it on the conveyor belt.

[0047] During operation, the push rod 19 enters the T-slot 30 upward, and the push rod 19 lifts the T-plate 31, which stretches the second spring 33. At the same time, the air intake device 26 blows out gas, which is blown out from the air outlet 29 through the air pipe 27 and the conversion head 28. The gas is blown upward at an angle, and the gas helps the injection molded parts to be demolded faster. At the same time, the injection molded parts can also be cooled for a second time to facilitate the subsequent staff to take them, further improving the demolding efficiency.

[0048] When the automatic injection molding equipment is in use, the belt conveyor 1 conveys the lower mold 4 to the top of the positioning plate 7. At this time, the belt conveyor 1 stops working and the motor 203 is started. The output end of the motor 203 drives the rotating shaft 204 to rotate, and drives the threaded rod 205 to rotate under the transmission of the first belt transmission 206. The threaded rod 205 drives the slider 207 to slide horizontally along the notch of the belt conveyor 1. The slider 207 drives the support rod 208 to rotate. Under the restriction of the rotating drum 201 and the spline shaft 202, the support rod 208 drives the positioning plate 7 to move upward. At the same time, the positioning plate 7 drives the spline shaft 202 to slide upward along the rotating drum 201. At the same time, the threaded rod 205 drives the rotating drum 201 to rotate through the first bevel gear 304, and the rotating drum 201 drives the spline shaft 202 to rotate. The spline shaft 202 passes through the second The transmission of the bevel gear 305 drives the screw rod 302 to rotate, and the screw rod 302 drives the two sliding blocks 303 to approach each other, and the sliding blocks 303 drive the two clamping plates 301 to approach each other, so as to position the lower mold 4 so that the lower mold 4 is directly opposite to the upper mold 5 for mold closing to avoid deviation during mold closing, and the molten raw material in the barrel 8 is injected into the upper mold 5 and the lower mold 4 through the discharge pipe 9 for injection molding, and the coolant is injected between the mounting seat 6 and the upper mold 5 through the liquid inlet pipe 10 to cool the injection molded part. When the mold is opened, the positioning plate 7 drives the lower mold 4 away from the upper mold 5, and at the same time, the positioning plate 7 drives the connecting rod 12 to move downward, and the connecting rod 12 drives the pressing plate 13 to move downward, and the pressing plate 13 squeezes the airbag 11, and the gas inside the airbag 11 is blown to the bottom of the lower mold 4 through the air inlet pipe 14 and the air hole 15, so as to further cool the lower mold 4;

[0049] The positioning plate 7 places the lower mold 4 on the conveyor belt. At this time, the conveyor belt runs to transfer the lower mold 4 to the top of the ejector rod 19. At this time, the next lower mold 4 is transferred by the conveyor belt to the bottom of the upper mold 5. Therefore, when demolding, the next lower mold 4 is performing mold closing injection molding, thereby enabling continuous production and improving production efficiency. When demolding, the positioning plate 7 rises and drives the mounting frame 17 to rise. The mounting frame 17 drives the ejector rod 19 to rise through the connecting plate 18 to eject the injection molded part in the lower mold 4 out of the lower mold 4. At the same time, the rotation of the screw rod 302 will drive the transmission shaft 23 to rotate through the second belt transmission 25. The transmission shaft 23 drives the cam 24 to rotate. The cam 24 squeezes the connecting plate 18 to drive the connecting plate 18 to rise, and the connecting plate 18 drives the ejector rod 19 and the connecting block 20 rise, the connecting block 20 slides upward along the guide rod 21 and compresses the first spring 22, and then the first spring 22 is reset, so that the connecting plate 18 drives the ejector rod 19 to vibrate longitudinally, and the ejector rod 19 vibrates the lower mold 4 while ejecting the injection molded part, and the ejector rod 19 enters the T-slot 30 upward, and the ejector rod 19 lifts the T-plate 31, and the T-plate 31 stretches the second spring 33. At the same time, the air intake device 26 blows out gas, which is blown out from the air outlet 29 through the air pipe 27 and the conversion head 28. The gas is blown upward at an angle, and the gas helps the injection molded part to be demolded faster. At the same time, the injection molded part can also be cooled for a second time to facilitate the subsequent staff to take it, further improving the demolding efficiency.
