The processing technology for injection molding comprises the following working steps:
s1, preparing materials: preparing an injection mold 11 and an injection material, and pouring the injection material into the feeding pipe 20;
s2, fixing a mold: sequentially clamping the injection molds 11 on the clamping plate 10, and starting the first micro motor 7;
s3, injection molding: when the clamping plate 10 and the injection mold 11 rotate to the lowest side, the telescopic rod 13 is started to extend, the injection pipe 17 is pushed to abut against a pouring gate 111 of the injection mold 11, the second micro motor 27 is started to drive the threaded rod 19 to rotate, and injection molding materials are injected into the injection mold 11;
s4, blanking: after the injection mold 11 is filled with the material and is far away from the injection pipe 17, the first micro motor 7 automatically drives the filled injection mold 11 to be far away from the injection pipe 17. The next injection mould 11 is moved against the injection pipe 17 and the injection mould 11 is removed from the clamping plate 10 to complete the injection.
According to the invention, the first micro motor 7 is started to drive the incomplete gear 8 to rotate, the incomplete gear 8 rotates to drive the power gear 5 to rotate through meshing, and when the power gear 5 is not meshed with the incomplete gear 8, the incomplete gear 8 cannot drive the power gear 5 to rotate, so that when the first micro motor 7 drives the incomplete gear 8 to continuously rotate, the power gear 5 intermittently rotates.
The power gear 5 and the rotary table 6 are both fixedly connected with the rotating shaft 4, so that the rotary table 6 intermittently rotates along with the power gear; the injection mold 11 is clamped on the clamping plate 10 and can slide within a certain range, when the rotary table 6 rotates to enable a certain injection mold 11 to move to the lowest side, the telescopic rod 13 is started to enable the certain injection mold 11 to move, so that the circular tube 21 on the injection tube 17 is just inserted into the pouring gate 111 of the injection mold 11, the second micro motor 27 is started to enable the circular tube to drive the friction plate 28 to rotate at a constant speed, and the friction plate 28 abuts against the friction roller 29 to drive the friction roller 29 to rotate at a constant speed. The friction roller 29 drives the threaded rod 19 in the injection molding pipe 17 to rotate, and then the injection molding material in the injection molding hole 18 is filled into the pouring channel 111;
when the injection material is injected into the pouring gate 111, the power gear 5 is not engaged with the incomplete gear 8, the injection mold 11 is kept stationary, when the injection mould is filled with the injection material, the pressure in the pouring channel 111 increases, and the injection mould 11 is moved away from the injection pipe 17 by continuously injecting the injection material into the injection mould until the round pipe 21 is separated from the pouring channel 111, at which time the second spring 32 pushes the extrusion plate 31 and the Z-shaped rod 30 to move synchronously, and then the second micro motor 27 moves towards the direction close to the injection molding pipe 17, in the process, the friction plate 28 is always pressed against the friction roller 29, and because the friction roller 29 is of a circular truncated cone structure, when the friction plate 28 is moved in the direction of the injection pipe 17, the rotational speed of the friction roller 29 is reduced, namely, the rotating speed of the threaded rod 19 is reduced, the injection speed of the injection molding material is reduced, so that the second micro motor 27 can be closed by a worker in time, and the injection molding material is prevented from leaking to the outer side of the injection mold 11.
After injection molding of one injection mold 11 is completed, the incomplete gear 8 is meshed with the power gear 5 again to drive the incomplete gear to rotate, so that the next injection mold 11 moves to the lowest end and repeats the operation, and injection molding work is continued, and in the stopping process of the turntable 6, a worker can take down the injection mold 11 which is subjected to injection molding on the turntable 6 and mount the injection mold 11 to be subjected to injection molding, so that continuous processing is facilitated.
When the second micro motor 27 moves, the sliding column 26 fixed with the second micro motor 27 moves along with the second micro motor 27, and under the action of the first spring 25, the sliding column 26 slides relative to the sliding sleeve 24, so that the friction plate 28 is ensured to be always abutted against the friction roller 29. During the movement the slide 23 slides in the slide groove 22.
