Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and particularly relates to a slider delayed secondary core-pulling structure. Background Art

[0002] With the development of industrial technology, the structures of mold injection products are becoming more and more complex. The conventional mold structures in the past are increasingly difficult to meet the ever-changing product requirements. In molds, sliders are common component mechanisms that complete parts that cannot be completed by one-way mold opening of products. Core-pulling is used to handle positions on the parting surface of products that cannot be demolded and belongs to the "undercut treatment system".

[0003] In the prior art, for some products in which sliders participate in molding, such as lamp brackets, there are many fine parts such as thin rods and bumps on the product contact surfaces of the slider forming surfaces. If the sliders are directly pulled out as usual, it often causes pulling deformation and damage to the products, and the effect is poor. Therefore, a slider delayed secondary core-pulling structure is needed. Summary of the Utility Model

An insert fixing plate is fixedly connected to the top of the slider seat, and a pressing block is fixedly connected to the outside of the slider seat. Due to the setting of the limiting block, it is beneficial to limit the stroke of the main insert.

[0010] Preferably, a chute is provided at the corresponding position of the wear-resistant plate and the shovel, and the shovel is slidably connected to the inside of the wear-resistant plate. Due to the setting of the shovel, it is beneficial to apply a locking force to the main insert.
