Firstly starting a first electric telescopic rod 2 before injection molding, after the output end of the first electric telescopic rod 2 stretches, abutting an injection molding upper die 3 with an injection molding lower die 4, at the moment, adding injection molding materials into an injection molding feed hopper 27 to enable the injection molding materials to enter the first fixed frame 11 through a through groove 36, starting a transmission motor 13, starting the transmission motor 13, rotating an injection molding raw material conveying screw 12 with the output end after the transmission motor 13 starts, starting conveying injection molding raw materials into a plastic raw material conveying pipe 10 after the rotation of the injection molding raw material conveying screw 12, and carrying out injection molding through an injection molding machine injection molding head 9 after the plastic raw material conveying pipe 10 enters an injection molding machine heating cavity 8 for heating, wherein the injection molding machine injection molding head 9 injects the injection molding raw materials into a die formed by the injection molding upper die 3 and the injection molding lower die 4 for injection molding;
firstly, the second electric telescopic rod 6 is started, the injection molding machine sliding base 7 with the output end of the second electric telescopic rod 6 slides and retreats along the inner wall of the injection molding machine sliding rail 5, at the moment, the injection molding machine injection molding head 9 gradually withdraws from the injection molding lower die 4, the first sliding frame 14 moves along with the soft guide track 18 on the inner wall of the first sliding frame 14 while the first sliding frame 14 moves along with the movement of the injection molding machine sliding base 7, at the moment, along with the movement of the soft guide track 18 at an inclined angle, a part of the soft guide track 18 always keeps an inclined state, and slides in a space formed between the first guide rod 32 and the second guide rod 33 which are in sliding contact with the outer wall of the soft guide track 18, so that the injection molding feed hopper 27 can be caused to relatively move along the surface of the soft guide track 18 through the first guide rod 32 and the second guide rod 33, and in the process of moving the relative position of the injection molding feed hopper 27, the soft guide 18 is continuously changed in shape through the sliding position of the first guide rod 32 and the second guide rod 33, and therefore, a part of the soft guide track 18 always keeps an inclined state, and the injection molding feed material can continuously enter the soft guide track 18 from the position of the injection molding feed hopper 27 to the position of the soft guide track 18 continuously through the position of the injection molding feed hopper 27;

the problem that in the injection molding process, the injection molding end of the injection molding machine moves synchronously due to the fact that the blanking hopper is large in size generally and inconvenient to follow in the injection molding process is solved.
Example 2
In this embodiment, the soft guide track 18 is easily deformed and stretched due to the soft characteristic of the soft guide track 18 under the long-term use due to the heavy weight of the first inclined surface mechanism, and the improvement is made on the basis of the embodiment 1, specifically, referring to fig. 1-7, the outer wall of the bolt 15 is in threaded connection with the inner wall of the first sliding frame 14, the end portion of the bolt 15 is rotatably connected with the moving plate 16, the outer wall of the moving plate 16 is fixedly connected with the outer wall of the soft guide track 18 through the first return spring 17, the moving plate 16 which is rotatably connected with the end portion of the bolt 15 is driven to move out of the first sliding frame 14 due to the threaded connection relationship between the moving plate 16 and the first sliding frame 14 after the bolt 15 is screwed, at this time, the moving plate 16 stretches the first return spring 17 outwards, so that the tension of the soft guide track 18 at the other end of the first return spring 17 is enhanced after the deformation, and the length of the soft guide track 18 is adjusted.
In this embodiment, since the first incline mechanism is heavy, the soft guide track 18 is easily deformed and stretched due to its soft nature under long-term use;
Therefore, after the soft guide track 18 is deformed, the bolt 15 is screwed, and the bolt 15 is screwed to drive the moving plate 16 with the end part thereof rotationally connected to move outwards of the first sliding frame 14 due to the threaded connection relation between the bolt 15 and the first sliding frame 14, at this time, the moving plate 16 stretches the first return spring 17 outwards, so that the tension of the soft guide track 18 at the other end of the first return spring 17 is enhanced after the deformation, and the length of the soft guide track 18 is adjusted;
Since the soft guide track 18 is a consumable item, and since the new soft guide track 18 is in a tense state after being installed when the new soft guide track 18 is replaced, the soft guide track 18 may be broken directly due to the tense state of the soft guide track 18 when the first incline mechanism ascends along the soft guide track 18, and the soft guide track 18 may be loosened by rotating the bolts 15;
The problem of soft guide track 18 length increase that is caused by soft characteristic of soft guide track 18 being easy to deform and stretch under long time use is solved.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
