DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 A flame retardant PC / ABS material injection molding equipment, comprising an injection molding machine 1 and a mixing box 2, wherein the mixing box 2 is provided at one end of the injection molding machine 1, and the mixing box 2 is used to feed the material at the feeding end of the injection molding machine 1, and the injection molding machine 1 is a conventional structure on the market, and will not be described in detail in this article; the injection molding equipment also includes:

[0026] A mixing component, the mixing component includes a box cover 3, a first motor 4 and a stirring piece. The box cover 3 is adapted to the upper opening of the mixing box 2. The output end of the first motor 4 passes through the center of the box cover 3 and is connected to the stirring piece. The box cover 3 covers the mixing box 2. The servo motor output end of the first motor 4 passes through the center of the box cover 3 and is connected to the stirring piece. When the material enters the mixing box 2 through the feed hole 11, the first motor 4 drives the stirring piece to rotate, fully stirring and mixing the material in the mixing box 2, so that the flame retardant and other additives are evenly dispersed in the PC / ABS material, ensuring the quality and stability of the mixed material, and providing high-quality mixed material for subsequent injection molding;

[0027] The batching component includes a support ring 5, an elastic member, a mounting seat 6, a material transfer box 7, an auger 8, a second motor 9 and a loading frame 10. A loading frame 10 is arranged above the material transfer box 7, and an auger 8 is arranged in the material transfer box 7. The output end of the second motor 9 passes through the material transfer box 7 and is connected to the auger 8. A feeding hole 11 adapted to the output end of the material transfer box 7 is arranged on the box cover 3. A mounting seat 6 slidably connected to the support ring 5 is arranged below the material transfer box 7. The support ring 5 is passed through the mounting seat 6. The two ends of the elastic member are respectively connected to the mixing box 2 and the mounting seat 6. The feeding hole 11 and the material transfer box 7 are arranged in several groups. In actual use, it is necessary to proportion and feed each principle. For this purpose, multiple loading frames 10 can pre-store different materials, such as PC / ABS materials, flame retardants and other additives, to provide sufficient material reserves for continuous production. The second motor 9 servo motor drives the auger 8 in the material transfer box 7 to rotate. The rotation of the auger 8 will push the material from the loading frame 10 to the output end of the transfer box 7, and finally enter the mixing box 2 through the feed hole 11. Since the second motor 9 adopts a servo motor, it can accurately control the rotation speed of the auger 8, thereby accurately controlling the material delivery amount and realizing the precise proportion of different materials. The feed hole 11 and the transfer box 7 are set to several groups. Different materials can enter the corresponding transfer box 7 from different loading frames 10 respectively, and then enter the mixing box 2 for mixing according to the set ratio, meeting the requirements of precise proportion and continuous supply of different materials in the continuous production process. At first, the elastic member is in a contracted state, the mounting seat 6 is slidably connected with the support ring 5 and close to the mixing box 2, and the mixing box 2 is stably plugged with the feed hole 11. The first motor 4 and the second motor 9 both adopt stable servo motors. It should be noted that the loading frame 10 only plays the role of temporarily carrying materials, and it can be externally connected with a negative pressure feeding device to ensure continuous feeding.

[0028] In actual use, the elastic member includes a spring 12 and a telescopic rod 13. The spring 12 is sleeved on the telescopic rod 13. Both ends of the spring 12 and the telescopic rod 13 are respectively connected to the mixing box 2 and the mounting seat 6. The spring 12 facilitates the resetting of the mounting seat 6, and the telescopic rod 13 ensures the stable movement of the mounting seat 6.

[0029] In actual use, it is necessary to remove the box cover 3 regularly in order to clean the inner wall of the mixing box 2. At this time, it is necessary to synchronously adjust the positions of several groups of mixing boxes 2. For this purpose, the injection molding equipment also includes a position adjustment component, which includes a lifter 14, an adjustment ring 15 and an inclined plate 16. An inclined plate 16 is also provided below the mounting seat 6. The lifter 14 passes through the support ring 5 and is connected to the adjustment ring 15. The adjustment ring 15 contacts the inclined surface of the inclined plate 16. When the hydraulic cylinder of the lifter 14 is in the production state, the lifter 14 drives the adjustment ring 15 to descend to the lower end. At this time, the elastic member spring 12 and the telescopic rod 13 are in a contracted state, and the transfer box 7 moves downward under the action of the elastic member. Its output end is inserted into the feed hole 11 to form a sealed connection to ensure that the material can be smoothly transported from the transfer box 7 to the mixing box 2. When the transfer box 7 needs to be maintained, cleaned or replaced, the lifter 14 is started to rise. The lifter 14 drives the adjustment ring 15 to rise, and the adjustment ring 15 contacts the inclined surface of the inclined plate 16 and pushes the inclined plate 16 to move upward. Since the inclined plate 16 is connected to the mounting seat 6, the mounting seat 6 will slide on the support ring 5 and drive the transfer box 7 to move upward, so that the transfer box 7 withdraws from the feed hole 11, and the transfer box 7 is separated from the feed hole 11, which is convenient for subsequent operations. The guide rod 17 set on the adjustment ring 15 passes through the support ring 5, plays a guiding role, and ensures the stability and accuracy of the lifting process of the adjustment ring 15. The lifter 14 is set to two groups of symmetrical arrangements. Both groups of lifters 14 use hydraulic cylinders with stable operation and are synchronized by a synchronization valve to ensure the stability of the movement of the adjustment ring 15.
