Description

Technical Field

[0001] The present application relates to the field of nano injection molding, and in particular to a nano injection molding device with an anti-cracking structure. Background Art

[0002] Nano-molding (NMT) is the abbreviation of a mold injection molding technology that combines metal and plastic. It is a new technology that directly injects engineering plastics onto a processed metal surface to achieve a more perfect and strong combination. It is used to replace traditional gluing, in-mold coating injection, and metal riveting technologies to achieve the purpose of lighter, thinner, and more textured products. This processing technology has been widely used in the production of electronic and electrical housings, mainly in the metal housings of 3C products such as mobile phones.

[0003] Existing nano injection molding devices are very prone to cracking during the injection molding process, which damages the quality of the product and greatly affects the production efficiency. The reason for the cracking is mostly due to cooling problems. Spraying water is a common cooling method, and artificial water spraying is often used to cool the injection molding material. This method greatly increases labor costs and reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a nano injection molding device with an anti-cracking structure. Figure 1-Figure 4A nano injection molding device with an anti-cracking structure includes a frame 1, grooves 2 are provided on both sides of the frame 1, an electric push rod 5 is arranged on the top of the inner side of the frame 1, a nano injection molding table 6 is arranged at the bottom of the electric push rod 5, a movable table 3 is arranged below the nano injection molding table 6, an electric slide rail 4 is arranged at the bottom of the movable table 3, a slide groove 18 is opened on one side of the movable table 3 and penetrates the movable table 3, a cross plate 15 is slidably connected to the slide groove 18, and a spray head 8 is connected to both ends of the cross plate 15, a motor 14 is arranged on one side of the movable table 3, a screw rod 16 is connected to the output shaft of the motor 14, one end of the screw rod 16 extends through the slide groove 18 and is threadedly connected to the cross plate 15, a water pipe 19 is arranged at the bottom of the spray head 8, and a water pump 17 is connected to one end of the water pipe 19.

[0022] By adopting the above technical solution, the nano injection molding process is divided into two stages. By first injecting the low-pressure layer and then the high-pressure layer, the internal stress of the product is gradually reduced and the risk of cracking is reduced. After the injection molding is completed, the motor 14 drives the screw rod 16 to rotate. The rotation of the screw rod 16 can move the spray head 8 threadedly connected to the screw rod 16. The water pipe 19 moves with the spray head 8. The water pump 17 at the bottom draws water to the spray head 8 to spray it on the injection molding material after the injection molding is completed for cooling treatment to prevent it from cracking.

[0023] Reference Figure 1 and Figure 2 There are two groups of nano injection molding tables 6, which are fixedly connected to the electric push rod 5. The bottoms of the two groups of nano injection molding tables 6 are provided with clamping columns 7.

[0024] By adopting the above technical solution, the two groups of nano injection molding tables 6 are respectively a low-pressure layer and a high-pressure layer, which divide the injection molding process into two parts, reducing the risk of cracking. The fixed connection with the electric push rod 5 allows the two groups of nano injection molding tables 6 to move up and down, facilitating injection molding.

[0025] Reference Figure 1 The movable platform 3 is slidably connected to the electric slide rail 4 , and there are two groups of electric slide rails 4 . The electric slide rail 4 is fixedly connected to the frame 1 .

[0026] By adopting the above technical solution, the movable table 3 can slide on the electric slide rail 4 and carry the injection molding material to perform two-stage injection molding processing.

[0027] Reference Figure 1 A fixing member 10 is provided on the top of the movable platform 3, and four corners of the top of the movable platform 3 are provided with card slots 9, and the card columns 7 and the card slots 9 are embedded.

[0028] By adopting the above technical solution, the fixing part 10 can fix the injection molding material to prevent the injection molding material from moving during the injection molding process and causing injection molding failure. The clamping column 7 and the clamping groove 9 are embedded in each other, so that the nano injection molding table 6 and the movable table 3 can be tightly connected together during the injection molding process to prevent deviation.

[0029] Reference Figure 4 A water tank 13 is provided inside the movable platform 3, and a transverse groove 11 is provided between the water tank 13 and the chute 18 corresponding to the water pipe 19.

[0030] By adopting the above technical solution, the temperature during the injection molding process can be controlled to ensure that the plastic material is quickly cooled and solidified in the injection mold, thereby improving production efficiency. The transverse groove 11 provides space for the water pipe 19 to move.

[0031] Reference Figure 3 A water inlet 12 is provided on one side of the movable platform 3 and is connected to a water storage tank 13 .

[0032] By adopting the above technical solution, the water inlet 12 can replenish the water in the water storage tank 13 to prevent the lack of water from being unable to spray for cooling and shaping.

[0033] The implementation principle of a nano injection molding device with an anti-cracking structure in an embodiment of the present application is as follows: placing the material to be injection molded on the fixing part 10, and starting the device after confirming that it is stable. The movable platform 3 slides along the electric slide rail 4 and slides to the bottom of the first nano injection molding platform 6 for the first injection molding process. The electric push rod 5 extends downward to drive the nano injection molding platform 6 to descend. The clamping column 7 is inserted into the clamping slot 9 to fix the two together and start nano injection molding. After the end, the electric push rod 5 retracts upward to separate the nano injection molding platform 6 and the movable platform 3. The movable platform 3 moves to the second nano injection molding platform 6 for processing. After the injection molding is completed, the movable platform 3 returns to the initial position, and the motor 14 drives the screw rod 16 to rotate. The rotation of the screw rod 16 allows the spray head 8 threadedly connected to the screw rod 16 to move. The water pipe 19 moves with the spray head 8. The water pump 17 at the bottom draws water to the spray head 8 to spray it on the injection molding material after the injection molding is completed for cooling treatment to prevent it from cracking.
