Floating type sliding block core pulling and demoulding mechanism

Abstract

The invention provides a floating type sliding block core pulling and demoulding mechanism. The floating type sliding block core pulling and demoulding mechanism comprises a slider angle pin, a compressing block screw, a long core sliding block body, a compressing block, a sliding block body spring, a sliding block body limiting pin, a sliding block body sliding groove plate, a blocking floating plate, a floating plate spring, a floating plate pull rod, a guide sleeve and a floating plate guide column. According to the floating type sliding block core pulling and demoulding mechanism in the technical scheme, in the mould shaping process of tubular plastic products with the small circular tube diameter and large length, mould design height can be effectively reduced, it can be guaranteed that ejection marks are not reserved on the products in the ejection process, the forming quality of the products is effectively guaranteed, and mould production and manufacturing cost and product injection molding cost are lowered. The mould structural design is reasonable, the structure is compact, work is stable, safety and reliability are achieved, and use is convenient.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a floating slider core-pulling and demoulding mechanism. Background technique [0002] The diameter is relatively small, but the length is long, and when the tubular plastic products are molded with a length of more than 200mm, such as figure 1 As shown, if the mold layout adopts the vertical layout along the length direction, the mold height and manufacturing difficulty of the mold will be increased; if the horizontal layout is adopted, there will be obvious ejection marks on the surface, which will affect the appearance quality of the product, and it will take a long time In view of this, when the horizontal layout design is adopted, a new core-pulling and demoulding mechanism must be designed, which not only reduces the height of the mold, but also ensures the appearance quality of the product.
