Description

Technical Field

[0002] The working principle of the injection molding machine is similar to that of a syringe used for injections. It uses the thrust of the screw to inject the plasticized molten plastic into a closed mold cavity, and obtains the finished product after solidification and shaping.

[0003] According to the patent with announcement number CN219445917U, an injection molding machine with convenient feeding is proposed. When in use, the raw materials are added to the inside of the feed port, and the raw materials enter the inside of the tube body through the feed hole. At this time, the double-headed motor is started to drive the bottom plate and the tube body to rotate. After the inside of the tube body is filled, it rotates to the position of the discharge hole and falls into the inside of the injection molding tube. At this time, there is no feed hole on the top plate above the tube body, so no excess raw materials will enter, so that quantitative feeding can be carried out. After the feeding is completed, the machine continues to rotate to complete the filling, and multiple tube bodies can be quantitatively fed in batches.

[0004] However, the injection molding machine with convenient feeding generally feeds plastic particles through a screw pusher, and the feeding funnel and the conveying pipe of the screw pusher are fixed. When the angle of the screw pusher is adjusted, the angle of the feeding funnel will also change accordingly. When feeding at a large angle, the plastic particles are easy to flow out from the lower part of the feeding funnel. Therefore, a feeding mechanism of an injection molding machine for plastic precision processing is proposed to solve the above problem. Utility Model Content
