Description

An injection molding mechanism with raw material color mixing and stirring function

Technical Field

The utility model relates to the technical field of injection molding color adjustment, in particular to an injection molding mechanism with raw material color adjustment and stirring functions.

Background Art

Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. In the injection molding process, the raw materials need to be colored. The granular materials in the common plastic parts masterbatch coloring method are used by actually mixing the plastic with the masterbatch to actually deliver the mixture or masterbatch to the injection molding machine.

The color adjustment part of the raw material of the traditional injection molding mechanism only uses the stirring rod to stir in the horizontal direction. The stirring and mixing effect achieved in this way is relatively poor, resulting in a long mixing time and low efficiency. In addition, after the mixing is completed, the mixed material needs to be put into the heating box for heating. The feeding port is generally narrow and there is a possibility of blockage. How to solve this problem is what we need to consider.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Referring to Fig. 1-Fig. 3, an injection molding mechanism with raw material color mixing and stirring function comprises a barrel 1, a feed port 2 is arranged at the inner top of the barrel 1, a discharge port 5 is arranged at the inner bottom of the barrel 1, a mounting frame 4 is installed on the right side of the barrel 1, the barrel 1 is mounted on the upper end of the heating device through the mounting frame 4, and the discharge port 5 is located inside the feed port of the heating device, the outer wall of the discharge port 5 is in a fitting state with the inner wall of the feed port of the heating device, and the inner bottom surface of the barrel 1 is a conical surface, which is convenient for the comprehensiveness of subsequent discharge;

The mixing mechanism includes a rotating rod 9 vertically arranged in the cylinder 1, a plurality of stirring rods 10 are fixedly connected to the outer side of the rotating rod 9, the lower end portion of the rotating rod 9 extends into the discharge port 5 and is fixedly connected to a circular plate 8, the outer side of the circular plate 8 is slidably connected to the inner side of the discharge port 5, and the outer side of the lower end portion of the rotating rod 9 is fixedly connected to a spiral blade 7;

The driving mechanism is used to drive the mixing mechanism. The driving mechanism includes a motor 3 installed at the upper end of the cylinder 1. The output shaft of the motor 3 extends into the cylinder 1 and is fixedly connected to a rectangular rod 6. A rectangular groove 12 is formed at the upper end of the rotating rod 9. The lower end of the rectangular rod 6 extends into the rectangular groove 12 and is slidably connected to the inner wall of the rectangular groove 12.

The lifting mechanism is used to move the rotating rod 9 up and down. The lifting mechanism includes a hydraulic telescopic rod 11 fixedly connected to the top of the cylinder 1. The telescopic end of the hydraulic telescopic rod 11 is fixedly connected to a lifting plate 13. The rotating rod 9 passes through the lifting plate 13 and is rotatably connected to the lifting plate 13 through a bearing. The bearing can not only ensure the rotational connection, but also play a supporting role.

In the utility model, when in use, firstly, a proper amount of masterbatch and raw materials are put into the barrel 1 through the feed port 2, and then the motor 3 is started, and the motor 3 partially rotates the rotating rod 9 through the rectangular rod 6, so that the multiple stirring rods 10 rotate, and the rotation of the multiple stirring rods 10 causes the masterbatch and the raw materials to be mixed;

During this process, the hydraulic telescopic rod 11 can be started to reciprocate up and down, thereby driving the rotating rod 9 to move up and down, so that it moves up and down in a rotating shape, thereby improving the stirring and mixing efficiency (the up and down movement range should not be too large to avoid the circular plate 8 leaving the discharge port 5);

After the mixing is completed, the hydraulic telescopic rod 11 is started to extend, so that the rotating rod 9 and the circular plate 8 move downward until the circular plate 8 is located at a certain height from the upper end surface of the heating device. At this time, the motor 3 is started again, so that the rotating rod 9 drives the spiral blade 7 to rotate, and the mixed material moves down into the heating device. The use of spiral pushing can effectively avoid blockage. After the mixed material is completely discharged into the heating device, the hydraulic telescopic rod 11 can be started to move back, so that the circular plate 8 moves back to the inside of the discharge port 5 again, and the discharge port 5 is sealed (that is, the feed port part of the heating device is sealed), which can ensure that the heating device is in a sealed state when working to avoid heat leakage.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
