AI Technical Summary

Technical Problem

When existing slider molds are used to process the undercut structure of soft rubber and silicone products, it is difficult to demold smoothly after injection molding, resulting in low production efficiency and easy deformation or tearing of the product.

Method used

A mold structure with delayed slider extraction is designed, which includes an upper mold base, an upper stripping plate, a lower stripping plate and a bottom plate. The slider is provided with a shift block hole and a shift block. The clearance between the shift block and the slider, combined with the precise positioning of the retreat insert, can achieve delayed slider extraction, avoid mold interference, and ensure smooth product demoulding.

Benefits of technology

The molding effect and structural stability of the product are improved, the mold structure is optimized, the product can be produced smoothly, the production efficiency is improved and the cost is reduced.

Abstract

The utility model relates to the technical field of dies for pulling out a sliding block in a delayed manner, and discloses a die structure for pulling out a sliding block in a delayed manner, which comprises an upper die holder, an upper stripping plate, a lower stripping plate and a bottom plate, the upper die holder and the upper stripping plate are mounted, the upper stripping plate and the lower stripping plate are mounted, and the lower stripping plate and the bottom plate are mounted. A sliding block delay extraction structure is arranged in the upper stripping plate and the lower stripping plate, the sliding block delay extraction structure specifically comprises two sliding blocks arranged between the upper stripping plate and the lower stripping plate, and block shifting holes are formed in the sliding blocks. After injection mold opening, the ejector rod ejects the lower stripper plate to push, at the moment, the sliding block is limited by delayed core pulling and the shifting block, when separation movement needs to be carried out, the retreating insert is separated from a matched movable plane formed by the retreating insert and the bottom of the sliding block, then the sliding block is moved to be shifted outwards, the mold structure does not interfere with the mold structure, and a product is taken out after ejection is completed. Therefore, the effect of pulling out the sliding block in a delayed manner is achieved.
