After injection molding, the temperature of the plastic product and the mold surface is relatively high. The product is taken out after natural cooling, and its cooling efficiency is low. In addition, the product is completely embedded in the mold and is not easy to take out, which makes its surface easily worn during the process of clamping the product. Utility Model Content

[0006] Preferably, the air-cooled lifting mechanism includes a motor fixedly mounted on the mold frame, the output end of the motor is fixedly connected to a first gear, the outer surface of the first gear is meshingly connected to a second gear, and the air-cooled lifting mechanism can guide the airflow into the spiral air duct inside the mold table to accelerate its cooling and facilitate lifting and removing the product.
[0007] Preferably, a screw barrel is fixedly connected to the top of the second gear, a screw rod is threadedly sleeved on the inner surface of the screw barrel, and the top of the screw rod is rotatably connected to the bottom of the lifting platform, and the output end of the screw barrel and the motor respectively pass through one side of the protective box and are rotatably connected. The purpose of designing the protective box is to effectively protect the two sets of gears.

[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The plastic processing mold assembly can generate upward airflow when the fan blades rotate through the air-cooling lifting mechanism. The airflow enters the spiral air duct inside the mold table. The spiral air duct can increase the contact time between the airflow and the surface of the mold table, which can increase the convection heat exchange effect.

[0020] Through the above technical solution, when the device is in use, the plastic raw material is injection molded in the mold table 2, and the air flow can be introduced into the spiral air duct 3 through the air-cooled lifting mechanism to accelerate the cooling of the mold table 2 and the plastic product. With the upward movement of the lifting platform 4, the plastic product can be easily taken out after cooling to avoid damage to the plastic product when clamping it.
[0021] Specifically, the air-cooled lifting mechanism includes a motor 6 fixedly mounted on the mold frame 1 , an output end of the motor 6 is fixedly connected to a first gear 7 , and an outer surface of the first gear 7 is meshingly connected to a second gear 8 .
[0022] Through the above technical solution, turning on the motor 6 can drive the first gear 7 to rotate, and then link the second gear 8 to rotate.
[0023] Specifically, a screw barrel 9 is fixedly connected to the top of the second gear 8 , a screw rod 10 is threadedly sleeved on the inner surface of the screw barrel 9 , and the top of the screw rod 10 is rotatably connected to the bottom of the lifting platform 4 .
[0024] Through the above technical solution, the screw barrel 9 passes through the upper surface of the protection box 5 and is relatively limited by the protection box 5, so that the screw barrel 9 can only rotate but not move up and down.
[0025] Specifically, the outer surface of the screw barrel 9 is rotatably connected to the fan blade 11 , and the outer surface of the fan blade 11 is fixedly connected to the support plate 12 .
[0026] Through the above technical solution, the support plate 12 is designed between the two groups of blades of the fan blade 11, and the support plate 12 supports the vertical rod 13, so as to facilitate driving the fan blade 11.
[0027] Specifically, a vertical rod 13 is fixedly connected to the top of the support plate 12 , and an electric push rod 14 is fixedly installed on the outer surface of the mold frame 1 .
[0028] Through the above technical solution, after the vertical rod 13 is driven by the swing frame 16 , it will indirectly drive the fan blade 11 through the support plate 12 .
[0029] Specifically, the output end of the electric push rod 14 is fixedly connected with a boss 15 , the outer surface of the boss 15 is rotatably connected with a swing frame 16 , and one end of the swing frame 16 away from the boss 15 is rotatably connected to the top of the vertical rod 13 .
[0030] Through the above technical solution, the boss 15 is inverted in design, and after being pushed by the electric push rod 14 , the swing frame 16 will rotate along the surface of the boss 15 .
[0031] Working principle: During the use of the device, the plastic raw materials are hot-melt injection molded in the mold table 2. After the plastic product of the corresponding shape is injection molded, the temperature of the mold table 2 and the plastic product is relatively high. The plastic product needs to be taken out after cooling. At this time, the electric push rod 14 can be turned on to drive the boss 15 to move back and forth. During this process, the swing frame 16 will rotate along the surface of the boss 15, and the other end will rotate along the top of the vertical rod 13. The swing frame 16 will push and pull the vertical rod 13 during the deflection process, and then drive the fan blade 11 through the support plate 12, so that the fan blade 11 rotates back and forth along the surface of the screw barrel 9. The fan blade 11 will generate an upward airflow during the rotation process, and the airflow will enter the spiral-like air duct 3 inside the mold table 2. When the airflow passes through the spiral-like air duct 3, the spiral-like air duct can make The contact time between the airflow and the surface of the mold table 2 is increased, and due to the fast airflow velocity, the convective heat exchange effect can be increased, and the heat will be taken out more quickly, and finally discharged from the top of the mold table 2 with the airflow, thereby accelerating the cooling of the mold table 2 and the internal plastic product. After the plastic product is completely cooled, the motor 6 can be turned on to drive the first gear 7 to rotate, and the second gear 8 can be linked to rotate, and the screw barrel 9 will rotate synchronously with the second gear 8. During this process, the screw 10 will rotate along the inner wall of the screw barrel 9 while moving upward, and then lift the lifting platform 4 at the top, that is, at this time the plastic product will be lifted and moved upward, which is convenient for taking it out of the mold table 2. Compared with directly clamping the product in the mold table 2, it effectively avoids the wear of the product during the clamping process, and improves production efficiency and product quality.
