Stamping die

Abstract

The invention discloses a stamping die. The stamping die structurally comprises a stamping plunger rod, a negative pressure recoil disc seat, an upper parting panel, a die plate pressing groove, a lower parting surface block, a demoulding lining plate and a base plate block. The stamping plunger rod is matched with the negative pressure recoil disc seat, and the stamping plunger rod penetrates through a suction column cylinder ring to erect a folded plate negative pressure seat for collecting extraction liquid in a thick block of a shaft rotating stamping disc, so that overflowed and returnedstamping injection molding liquid can be effectively extracted to form a trace collecting and integrating effect. The recoil disc seat subjected to molding pressure guarantees the molding fitting degree of an integral stamping part, the upper and lower packaging efficiency of a template is improved, and the density of the bulged injection molding liquid forms overflow and return regulation and control, so that the sector pressure of a rack type sector brush plate rack and a spacer ball plate operated by the die is guaranteed. The material cost saving degree of stamping die processing is improved, careless mistakes of stamping are also corrected, and the die processing accuracy is improved.

Description

technical field [0001] The invention relates to a stamping die, which belongs to the field of dies. Background technique [0002] Mold is a mechanical equipment for processing injection molding of hardware and plastic products, which facilitates high-heat injection of injection molding liquid or metal liquid, improves the filling degree of the inner template groove, and then forms a die-casting operation through impact pressure to ensure hardware and plastic products. The technical processing is rigorous, and the shortcomings of the current technology that need to be optimized are: [0003] The central end of the stamping part is impacted up and down by the overall mold panel to form die-casting, and the diffuse pressure at the central end during the die-casting process will disperse the injection molding liquid on the edge, causing the phenomenon of pulling the edge to fill the edge seam, causing the edge to overflow the plate when demolding The rigid deformation operation...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a stamping die to solve the problem that the center end of the stamping part is impacted up and down by the overall mold panel to form die-casting, and the diffusion pressure at the center end during the die-casting process will disperse the edge The injection molding liquid caused the edge pulling phenomenon of the filling edge seam, which caused the rigid deformation operation of the edge overflow plate to whiten the center stamping part during demoulding, resulting in a decrease in the homogeneity of the mold stamping in the later stage, and poor demoulding yield. The degree of finishing and grinding of finished parts in the later stage consumes a large amount of engineering, which greatly reduces the molding quality of stamping dies.
