1. A skin manufacturing post-treatment method for an automobile collision dummy, comprising:
obtaining a skin layer to be treated, wherein the skin layer to be treated at least comprises: an epidermis layer and a muscle layer that is formed at a side of the epidermis layer; selecting a first machining area on the skin layer to be treated, and forming a first pouring portion on the first machining area; and grinding the first pouring portion, and causing a side, far away from the epidermis layer, of the first pouring portion to dip, to form a patching recess;
obtaining an epidermis layer to be treated, causing the epidermis layer to be treated to be above the first machining area, and a center of the epidermis layer to be treated to be on a central axis of the patching recess, and arranging a heating assembly above the patching recess, wherein the heating assembly has a heating space, and the epidermis layer to be treated is in the heating space;
applying a first pressure to the epidermis layer to be treated along the central axis of the patching recess, and driving the patching recess to move in a direction close to the heating assembly until the heating assembly is attached to an interior of the patching recess, and the epidermis layer to be treated; and
turning on the heating assembly, simultaneously heating the epidermis layer to be treated and the patching recess at a first preset temperature until accumulated heating time reaches first preset duration, and applying a second pressure to the epidermis layer to be treated along the central axis of the patching recess, wherein the second pressure enables the epidermis layer to be treated to be placed in the patching recess; and maintaining the second pressure for second preset duration until an outer wall of the epidermis layer to be treated is attached to an inner wall of the patching recess in a circumferential direction of the inner wall of the patching recess; wherein
the forming a first pouring portion on the first machining area comprises:
forming a first treatment portion on an epidermis layer of the first machining area by using a first cutting portion, wherein the first cutting portion has a second preset temperature; and
cutting the first treatment portion by using the first cutting portion, and forming the first pouring portion; wherein the first cutting portion has a third preset temperature; wherein
the second preset temperature is higher than the third preset temperature.
