Description

Technical Field

[0001] The present application relates to the field of injection molding machine technology, and in particular to an injection molding mechanism of an injection molding machine. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine; it is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. In modern industrial production, injection molding machines have become an indispensable and important equipment;

[0003] After searching, it is found that an injection molding mechanism of an injection molding machine disclosed in Chinese patent CN220095306U reduces the impact force generated by the falling of raw materials through two groups of buffer components, such as a material buffer box, a bearing seat, a material guide inclined plate, an electric push rod, a first hinge seat and a second hinge seat. The design has a good effect of reducing the impact force, and can better protect the raw material conveying structure of the injection molding machine, solving the problem that the injection molding mechanism of the original injection molding machine only reduces the impact force generated by the falling of raw materials through a spiral tube, and the effect of reducing the impact force is poor when there are more raw materials.

[0004] However, when the device is actually used, the material needs to flow into the barrel from the feed pipe after the impact is reduced by the buffer component. If a large amount of raw materials are added at one time, the feed pipe may be blocked, thereby affecting the transmission of the material, which is very inconvenient to use. For this reason, we urgently need to provide an injection molding mechanism for an injection molding machine.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to solve the problem that if too much raw material is added at one time, the feed pipe may be blocked, thereby affecting the transmission of the material and causing inconvenience in use, the present application provides an injection molding mechanism of an injection molding machine.

[0007] The injection molding mechanism of an injection molding machine provided in this application adopts the following technical solution:

[0008] An injection molding mechanism of an injection molding machine includes a heating box body, two feed hoppers are welded to the top of the heating box body, a servo motor is installed on the top of the heating box body, the output end of the servo motor passes through the heating box body and is installed with a rotating column, a plurality of stirring rods are evenly fixedly installed on the outer surface of the rotating column, a material guide pipe is fixedly installed on the bottom of the heating box body, a fixed rod is fixedly installed on the bottom of the rotating column, the fixed rod is located on the inner side of the material guide pipe, and a first auger blade is fixedly installed on the outer surface of the fixed rod.

[0009] Preferably, a material delivery cylinder is fixedly mounted on the bottom of the material guide tube, and the bottom of the material guide tube is connected to the inside of the material delivery cylinder, and a stepping motor is mounted on the right side of the material delivery cylinder.

[0010] Preferably, the output end of the stepper motor passes through the feeding cylinder and is connected to a connecting column, and a second auger blade is fixedly mounted on the outer surface of the connecting column.

[0011] Preferably, a discharge port is fixedly mounted on one end of the feeding cylinder away from the stepping motor, and the discharge port is arranged in a cone-shaped structure.

[0012] Preferably, the outer surface of the feeding cylinder is connected to a heating base, a plurality of electric heating rods are arranged on the inner side of the heating base, and the outer surface of one end of the feeding cylinder close to the discharge port is in contact with the plurality of electric heating rods.

[0013] Preferably, a heating device is fixedly mounted on the top of the heating base, and the heating device is electrically connected to a plurality of electric heating rods.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. A servo motor is installed on the upper end of the heating box to drive the rotating column and multiple stirring rods to rotate inside the heating box, thereby improving the stirring and mixing effect of the injection molding raw materials inside the heating box, making it difficult for the raw materials to solidify. At the same time, the rotation of the rotating column drives the fixed rod and the first auger blade to rotate inside the material guide pipe, and the material is evenly transported. When there is a lot of raw materials inside the heating box, the material guide pipe will not be blocked, which enhances the stability of the device during material feeding and ensures the injection molding efficiency of the injection molding machine;

[0016] 2. By setting a heating base at the discharge port of the feed barrel, and using a heating device to control the temperature of the electric heating tube inside the heating base, the material transmitted in the feed barrel is heated to avoid cooling and solidification of the injection molding material during the transmission process of the second auger blade inside the feed barrel, thereby affecting the subsequent injection molding effect and enhancing practicality.
