Automobile seat headrest mold ejection mechanism

Abstract

The invention discloses an automobile seat headrest mold ejection mechanism. The automobile seat headrest mold ejection mechanism comprises a seat plate, a connecting plate, two air cylinders, straight ejection blocks, a core-pulling push rod, a guide rod and an ejection rod; the two air cylinders are symmetrically installed on the upper surface of the seat plate along the center of the seat plateand located on the two sides of a mold core; a telescopic rod of each air cylinder is fixedly connected with the seat plate, a fixed part of each air cylinder is locked on the connecting plate through bolts, the connecting plate is placed between the seat plate and a push plate, the connecting plate is fixedly connected with the push plate, the connecting plate and the push plate are driven by the air cylinders to lift relative to the seat plate, and the ejector rod and the core-pulling push rod are installed on the push plate; the core-pulling push rod is connected to the core rod in a sleeved mode, the core rod is used for forming an inserting rod of a headrest workpiece, the core-pulling push rod pushes an outer ring of the inserting rod to be demolded, the plurality of straight ejection blocks are arranged on a supporting plate around the periphery of the bottom of a mold core, the bottoms of the straight ejection blocks are connected with the ejection rod, and the inner sides ofthe straight ejection blocks are flush with the inner side of the headrest workpiece. According to the automobile seat headrest mold ejection mechanism, the height of a headrest mold is reduced, so that the headrest workpiece is stressed uniformly, and damage to a connector clip and a central thin wall is avoided.

Description

technical field [0001] The invention belongs to the field of molds for auto parts, and in particular relates to a mold ejection mechanism for a headrest of an automobile seat. Background technique [0002] The function of the car seat headrest is to make the head more comfortable and protect the head under impact conditions. During long-term driving, the headrest can relieve fatigue and provide cushioning protection for the neck in the event of an emergency. Therefore, the quality of the car seat headrest is of great significance to ensure the safety of passengers and comfortable driving, and also puts forward requirements on the wall thickness, shape, strength and deformation of the headrest. As attached to the manual figure 1 As shown, there are many connectors at the bottom of the headrest of the car seat, and the displacement of the ejector mechanism may easily cause damage to the headrest workpiece. The current mold ejection mechanism for automobile seat headrest is ...
