Material pressing structure for preventing skylight opening base material from lacking material

The utility model discloses a material pressing structure for preventing skylight opening base materials from lacking materials, which comprises an upper die and is characterized in that a spring sleeve is arranged on the upper die, a plug screw and a spring are assembled in the spring sleeve, an ejector rod is assembled on the spring sleeve and connected with the spring, and a profiling pressing plate is connected onto the ejector rod with the spring. The mechanism is driven by the closing process of the die to firstly contact with a base material in the die cavity and effectively press the base material, so that the problem of shortage of the base material caused by contact and punching of a punching knife and the base material is solved, and the appearance defect that a product is uneven after edge covering is avoided. 本实用新型公开了一种预防天窗口基材缺料的压料结构，包括上模具，其特点是，所述的上模具上设弹簧套，弹簧套内装配螺塞和弹簧，所述的弹簧套上装配顶杆，顶杆与弹簧连接，所述的带弹簧的顶杆上连接仿形压板；该机构借助模具的闭合过程带动，在模腔内先接触基材，将其有效压住，解决因冲刀与基材接触并冲切而造成的基材缺料，避免产品包边后高低不平的外观缺陷。
