AI Technical Summary
Irregularly shaped shell products are difficult to demold after stamping, resulting in surface scratches and low production efficiency.
A stamping die suitable for irregularly shaped shells was designed. It adopts an upper and lower die structure, combined with a lifting mechanism and a positioning block. The stamping process of flat, inclined and curved surfaces is realized by the cooperation of clearance groove and extension part, and the lifting mechanism is used to realize rapid demolding.
It enables rapid demolding of irregularly shaped shells, ensuring the precision and smoothness of the product surface, and improving production efficiency and mold life.

Abstract
Claims
1. A stamping die suitable for irregularly shaped housings, comprising an upper die and a lower die; characterized in that: A stamping part is fixedly installed on the bottom side of the upper mold, and several positioning blocks are fixedly installed on the lower mold. A cavity part is installed between the positioning blocks in a sliding and lifting manner. The bottom side of the stamping part is the core surface, and the upper side of the cavity part is the inner cavity surface. The core surface presses on the upper side of the inner cavity surface to realize the stamping action. The outer side of the cavity component is formed with several clearance grooves. The cavity component is installed between several positioning blocks through the several clearance grooves. One of the positioning blocks is formed with a right-angle slot, and a first extension component is fixedly installed in the right-angle slot. A lifting mechanism is fixedly installed on the bottom side of the lower mold. The lifting mechanism drives the cavity component to move up and down between several positioning blocks. When demolding, the lifting mechanism drives the cavity component to move to the inside of the first extension component.
2. The stamping die for a profiled housing according to claim 1, characterized in that: The first extension has a first extended curved surface formed on it. One side edge of the first extended curved surface is flush with one side edge of the inner cavity surface. The bottom side of the upper mold has a recessed groove formed on it. A second extension is fixedly installed in the recessed groove. The second extension has a second extended curved surface formed on it. One side edge of the second extended curved surface is flush with one side edge of the core surface.
3. A press tool suitable for use with a profiled housing according to claim 2, wherein: The first flat key is inlaid and installed in the right-angle slot, and the bottom side of the first extension is formed with a first keyway. The first flat key is installed in the first keyway with clearance fit.
4. The stamping die for a profiled housing according to claim 2, characterized in that: A second flat key is embedded in the recessed groove, and a second keyway is formed on the upper side of the second extension. The second flat key is fitted into the second keyway with a clearance fit.
5. The stamping die for a profiled housing according to claim 2, characterized in that: The second extension is positioned above the first extension.
6. The stamping die for a profiled housing according to claim 1, characterized in that: The positioning block has a wear-resistant pad that can be detachably installed on the side near the clearance groove.
7. The stamping die for a profiled housing according to claim 1, characterized in that: The lower mold has several lifting holes formed inside, and a vertical rod is slidably installed inside the lifting holes. The upper end of the vertical rod abuts against the bottom side of the cavity part. The lifting mechanism is located below the vertical rod and drives the vertical rod to move up and down.
8. A stamping die suitable for irregularly shaped shells according to any one of claims 1 or 7, characterized in that: The lifting mechanism is provided in multiple ways, and a base plate is provided on the lower side of the multiple lifting mechanisms. Several through holes are formed on the bottom side of the lower mold, and several positioning shafts are fixedly installed on the bottom side of the base plate. The positioning shafts are slidably inserted into the through holes one by one.
9. A press tool suitable for use with a profiled housing according to claim 8, wherein: Several assembly blocks are fixedly installed on the base plate. The assembly blocks are formed with lifting holes, and the lifting mechanisms are installed in the lifting holes in a corresponding clearance fit.
