The utility model can push the plastic remained at the discharge port 120 of the injection molding machine out, thereby avoiding blocking the discharge port 120, improving the production and processing efficiency, reducing the risk of injection molding machine failure, and improving the economic benefit, in the initial state, the push plate 300 is arranged at one side of the discharge pipe 100 far away from the discharge port 120, the plastic raw material to be processed enters the discharge pipe 100 from the feed port 110, the first push rod 200 moves towards the discharge port 120, thereby driving the push plate 300 to move towards the discharge port 120 for pushing, the plastic raw material moves towards the discharge port 120 under the push of the push plate 300, because the cavity formed by the push plate 300 and the discharge pipe 100 is continuously reduced in the process that the push plate 300 moves towards the discharge port 120, the plastic raw material is extruded, so that part of the plastic raw material is pushed out from the discharge port 120, at this time, part of the plastic raw material which is not pushed out remains at the discharge port 120, the first push rod 200 moves towards the discharge port 120, the connecting portion 210 also moves towards the discharge port 120, as shown in fig. 5, in the moving process, the connecting portion contacts with the pushing block 430, the pushing block 430 is pushed to move towards the discharge port 120, the pushing block 430 drives the second pushing rod 410 to move towards the discharge port 120, the second pushing rod 410 is connected with the pushing head 450, so that the pushing head 450 extends out from the pushing pipe 400 under the driving of the second pushing rod 410, and pushes the plastic material remained at the discharge port 120 out of the discharge port 120, thereby completing pushing, wherein the first pushing rod 200 drives the pushing plate 300 to move and push the plastic material, the pushing plate 300 pushes the plastic material towards the discharge port 120, the second pushing rod 410 drives the pushing head 450 to move, and the pushing head 450 pushes the remaining plastic material out of the discharge port 120, thereby avoiding the discharge port 120 from being blocked and improving the processing efficiency.

Further, the connecting portion 210 is connected with the driving rod 220, the driving rod 220 is connected with the driving device 230, and the driving rod 220 is connected through the connecting portion 210, so that one driving device 230 drives the connecting portion 210 to move through the driving rod 220, all the first push rods 200 can be pushed to move at the same time, the efficiency is improved, and the cost is saved.

It should be noted that, the driving rod 220 is connected to the connecting portion 210 to drive all the first push rods 200 to move, so as to ensure that all the first push rods 200 move at the same time by the same distance, and ensure the moving distance and time accuracy, and if different driving devices 230 are used to drive each first push rod 200, the moving time between each first push rod 200 may have an error, and it cannot ensure that each first push rod 200 moves by the same distance.

In order to improve the precision, the driving device 230 is an electric cylinder, the precision can be ensured by using the electric cylinder for driving, the feeding speed can be adjusted according to the use requirement, the maintenance cost of the electric cylinder is low, and the noise is low.

In order to enable the second push rod 410 to automatically reset after the material pushing head 450 pushes the material, a return spring 460 is disposed between the second push rod 410 and the baffle 420, as shown in fig. 4, when the second push rod 410 pushes the material pushing head 450, the return spring 460 is compressed by the extrusion of the second push rod 410 and the baffle 420, after the material pushing head 450 pushes the material, the connecting portion 210 moves in a direction away from the discharge hole 120, and does not push the push block 430 any more, at this time, the return spring 460 returns to its original state under the action of elastic force, and the return spring 460 pushes the second push rod 410 to reset.

It should be noted that the initial length of the return spring 460 is greater than the moving distance of the second push rod 410 during pushing, so that it is ensured that the second push rod 410 can be restored to the initial position under the elastic force of the return spring 460 during the returning process.

In order to enable the plastic raw material to be extruded to the discharge port 120, the discharge pipe 100 is inclined towards the discharge port 120 to form a funnel structure, and the funnel structure enables the plastic raw material to be extruded to the discharge port 120 along the inclined surface of the funnel structure under the condition of being extruded, so that the discharge is facilitated.

In order to push out all the plastic materials remained at the discharge port 120, the width of the material pushing head 450 is equal to the width of the inner cavity of the discharge port 120, so that the plastic materials remained at the discharge port 120 can be pushed out.

It should be noted that, if the width of the material pushing head 450 is greater than the width of the inner cavity of the material outlet 120, the material pushing head 450 cannot enter the material pushing opening to push out the residual plastic material, and if the width of the material pushing head 450 is less than the width of the inner cavity of the material outlet 120, a part of the plastic material still remains on the inner wall of the material outlet 120 after the material pushing is finished.

Further, the push block 430 is connected with a connecting rod 440, the connecting rod 440 is connected with the second push rod 410, and the push block 430 is connected with the second push rod 410 through the connecting rod 440, so that the push block 430 located outside the material pushing pipe 400 can drive the second push rod 410 in the material pushing pipe 400.

In order to prevent the plastic material from being cooled too fast and solidified, the discharge pipe 100 is further provided with a heating plate 140, and the heating plate 140 heats the plastic material in the discharge pipe 100 to prevent the plastic material in the discharge pipe 100 from being cooled and solidified to block the discharge port 120.
