Title:
FLEXIBLE DEMOLDING DEVICE, CORE MOLDING DEVICE, AND CORE FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/205579
Kind Code:
A1
Abstract:
A flexible demolding device (11), comprising a flexible substrate (111) and a driving device (112). A plurality of forming holes (1110) are provided on the flexible substrate (111) and penetrate through the thickness direction of the flexible substrate (111). The driving device (112) drives the flexible substrate (111) to move continuously in a defined direction. The driving device (112) comprises a driving wheel (1121), a supporting wheel (1122) and a conveying belt (1123) which is sleeved between the driving wheel (1121) and the supporting wheel (1122). The flexible substrate (111) is fixed on the conveying belt (1123). One one hand, the demolding assembly no longer has a rigid structure. On the other hand, since the flexible substrate (111) can be fixed on the conveying belt (1123) by means of the connecting body (1130), the flexible substrate (111) can be easily replaced. Meanwhile, when the connecting body (1130) is provided with a protrusion, and the driving wheel (1121) is provided with a corresponding clamping groove (11211), the size precision of the forming holes (1110) on the flexible substrate (111) can be easily maintained. A core molding device applying the flexible demolding device (11) is further provided.
