AI Technical Summary
Technical Problem
In existing injection molding machine feeding mechanisms, the material remains in a flowing state when the valve is closed, causing a large amount of material to adhere to the baffle at the valve, affecting the blocking effect.
Method used
The baffle closing system is driven by an electric push rod and a motor. The electric push rod pushes the sliding connection between the push seat and the baffle. The suction force inside the feed cylinder and the gear meshing structure are used to achieve tight closure of the baffle and prevent material from adhering.
Benefits of technology
It effectively improves the material blocking effect in the feed barrel, avoids the appearance of material gaps, and ensures the smooth progress of the injection molding process.

Abstract
This utility model discloses a feeding mechanism for an injection molding machine, relating to the field of injection molding machine feeding technology. It includes a feeding cylinder with a support plate fixed to its outer wall, and a support frame connected to the top of the support plate. In this utility model, through the arrangement of a push seat, baffle, motor, and gears, when a closing operation between the baffle and the discharge pipe is required, a first electric push rod is activated, pulling the push seat upwards. Due to the upper-wide, lower-narrow structure of the inner side of the feeding cylinder, resembling a syringe, suction is generated, causing the material to settle under suction. The motor, electrically connected to the first electric push rod, is activated, driving the rotating shaft to rotate. This causes the gears to rotate the handwheel with meshing teeth on its outer wall, completing the work of driving the baffle. This closes the baffle with the discharge pipe, preventing a large amount of material from adhering and eliminating gaps, effectively improving the material blocking effect within the feeding cylinder.
