AI Technical Summary
Existing technologies struggle to efficiently mold and demold composite trash can outer containers. Traditional ejector pin demolding is difficult and costly, while robotic arm demolding occupies equipment space and incurs high costs.
The system adopts a combination structure of outer mold, core mold assembly, left end cover, right end cover and demolding baffle. Demolding is achieved by pushing each component horizontally with a cylinder. Demolding is completed by pushing the right end face of the outer barrel with the demolding baffle, ensuring uniform force distribution.
It achieves efficient injection molding and demolding of the outer barrel, with a simple structure, stable and reliable operation, and reduced costs.

Abstract
Claims
1. An injection mold for an outer barrel of a trash can, characterized by: Includes outer mold, core mold assembly, left end cap, right end cap, and demolding baffle; The left end cap is vertically arranged, with a hot nozzle in the middle of its left end face, an injection channel in its middle, and a flow divider on its right end face; the hot nozzle, the injection channel, and the flow divider are connected. The outer mold is set vertically. It is a shell with openings at both the left and right ends and a cylindrical cavity in the middle. Its left end face is connected to the left end cover by screws. The core mold assembly includes a cylindrical core and an end connector; the core is inserted into the cylindrical cavity of the outer mold; a gap area is provided between the outer wall of the core and the inner wall of the outer mold, which is the outer barrel forming cavity; The connecting seat is vertically arranged at the right end of the mold core and is connected to the vertically arranged right end cap by screws. The left end face of the mold core is provided with a second flow divider groove, which is a cross-shaped groove with a conical hole at its end. The tip of the conical hole is connected to the outer barrel forming mold cavity. A demolding baffle is fitted onto the right end face of the outer barrel forming mold cavity.
2. The injection mold for an outer barrel of a trash can according to claim 1, characterized in that: The demolding baffle has a cylindrical cavity in the middle, which is fitted onto the right end of the mold core, and its right end face is attached to the left end face of the connecting seat.
