Technical Field

[0001] The utility model relates to the technical field of automobile trim strip processing, in particular to an automobile trim strip injection mold which is easy to demould. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds. When producing automotive trims, injection molding is usually used.

[0003] Prior art CN212979063U proposes an injection mold for automotive interior parts that is easy to demold. The patent is provided with a blocking mechanism. The injection molding material enters the filling nozzle and then enters the cavity between the upper mold and the lower mold along the filling nozzle. Then the second motor drives the second gear to rotate, and the second gear drives the meshing rack to move, so that the rack and the baffle move in the upper mold until the baffle blocks the bottom of the filling nozzle, thereby blocking the filling nozzle and the cavity between the upper mold and the lower mold, preventing the connection between the injection molding material in the filling nozzle and the injection molding material in the cavity between the upper mold and the lower mold, and facilitating the cooling and molding of the injection molding material in the cavity, reducing the waiting time for demolding, and facilitating subsequent demolding.
