They are divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity. The product can then be removed by demolding.

The key points of its technical solution are that it includes a feeding barrel, a barrel and a screw. The screw is placed in the barrel and the two are gap-matched. The gap part is conductively connected to the feeding barrel. The feeding barrel has a feeding inlet, and the barrel has a barrel inlet. A detour component is conductively connected between the feeding barrel and the barrel. The detour component has a conductive detour interface and a detour outlet.

At the same time, by installing the lifting and rotating frame 7 on the crushing assembly 5, when the crushing assembly 5 rotates under the drive of the second drive motor 6, the lifting and rotating frame 7 can be driven to rotate synchronously, and then the raw materials fed are lifted and stirred by the rotating lifting and rotating frame 7, which facilitates the crushing assembly 5 to be better crushed and used. By installing the discharge head 8 at the lower end of the feed shell 4, the crushed raw materials can be discharged into the heat flow tube 2 at the lower end through the discharge head 8 when it is easy to use.

[0036] The implementation principle of an efficient and energy-saving injection molding machine in an embodiment of the present application is as follows: during actual use, the operator can turn on the heating mechanism on the heat flow tube 2 to preheat the heat flow tube 2. After the heat flow tube 2 is heated to a specified temperature, the first drive motor 3 can be started to drive the extrusion screw in the heat flow tube 2 to rotate, and then the second drive motor 6 is started to drive the crushing component 5 to rotate in the feed shell 4. Then, the raw materials can be added to ensure that the raw materials can be crushed by the crushing component 5 after entering the feed shell 4. At the same time, the raw materials are lifted and stirred by cooperating with the lifting and rotating frame 7. The crushed raw materials can pass through the filter plate 82 to continuously fall into the heat flow tube 2 of the love section, and the diversion shell 83 is set to ensure that the raw materials can be dispersed into the heat flow tube 2, thereby ensuring good melting efficiency.
