Abstract

The utility model provides a novel structure for product discharge, which comprises a pre-breaking structure, a segmented stamping structure and a blanking structure, wherein the pre-breaking structure breaks the connection points between a to-be-molded product and a material belt so as to thin the thickness of the connection points; then the segmented stamping structure is utilized for stamping materials, thereby the connection point is sunken into a product; finally the blanking structure is adopted to stamp the connection point between the product and the material belt off and enable the product to fall into a specific position. The novel structure for product discharge can prevent the surface of the product from generating burrs after the pre-breaking structure breaks the connection point and stamps the materials; even if the burrs are generated, the burrs are sunken into the product and can not affect the normal use of the product; moreover, the product is enabled to directly dropat the specific position through the blanking structure discharging materials; the product is prevented from dropping on a die or a machine tool, and the die can be protected from damage.
