Abstract

The utility model provides a transverse linked secondary core-pulling mechanism which comprises a large slide block (1), a small slide block (2) and a baffle (3). With the adoption of the successively linked transverse slide block spliced by the large and small slide blocks, a molded profile part with a large packaging force of a product is arranged on the small slide block and a molded profile part with a small packaging force of the product is arranged on the large slide block. A pulling hole for sliding a baffle block and pulling the large slide block later is arranged on the small slide block. The baffle block passes through a baffle block hole arranged on the large slide block and a pulling hole arranged on the small slide block to string the small slide block slidingly in a slide block hole arranged on the large slide block. During work, the small slide block is driven first to pull the core so as to demold the structural part with the large packaging force of the product. Then, the large slide block is pulled later by the baffle block to pull the core continuously so as to demold the structural part with the small packaging force of the product later, so that the product yield is improved, the production efficiency is improved, and the cost is lowered for injection molding production of the product with the overlarge packaging force on the profile on the outer side face.
