AI Technical Summary
Existing stamping molds are prone to breaking out of the edges and corners of the blanks when used, which hurts workers. The spring fatigue of the ejection mechanism after long-term use causes the molded parts to be unable to eject out quickly.
A protective stamping mold is designed, including a shielding mechanism and a lifting mechanism. The shielding mechanism reduces debris splash through a guide frame and a shielding plate. The lifting mechanism uses a spring and a push plate to achieve stable ejection of the molded parts.
It effectively reduces debris splash during stamping, improves the ejection stability of molded parts, and avoids worker injury and spring fatigue problems.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a protective stamping die. Background Art
[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. They are called cold stamping dies. Stamping is a pressure processing method that uses dies installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.
[0003] In the current existing technology, when the stamping die is used to stamp the material, the corners and debris of the blank will pop out during the stamping, thereby injuring the workers. In addition, after long-term use, the spring of the ejector mechanism will fatigue, resulting in the problem that the formed stamped parts cannot be ejected quickly. Therefore, it is necessary to design a protective stamping die to solve the above problems. Utility Model Content

[0006] Preferably, a guide bar is provided on the inner side of the guide frame, a guide groove is provided on the outer side of the shielding plate, and the guide bar is slidably installed in the guide groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. Through the designed shielding mechanism, the shielding mechanism is installed on the four sides of the upper die base and the lower die base when in use. When in use, the blank enters between the upper die base and the lower die base from the inside of the guide frame for stamping. During stamping, the shielding plate follows and descends to block the outside, thereby reducing debris splashing outward during stamping, and the shielding plate is guided by the guide frame, which is more stable during lifting and lowering.
[0013] 2. Through the designed jacking seat, pushing plate and second spring, when in use, the jacking seat and the inclined surface of the pushing plate cooperate.

Into the groove 9, the guidance between the guide groove 9 and the guide strip 10 facilitates the guidance of the lifting and lowering of the baffle plate 8; guide sleeves 3 are provided at the four corners of the lower surface of the upper die base 2, and guide slides 4 are provided at the four corners of the upper surface of the lower die base 1. The upper end of the guide slide 4 is slidably installed on the inner side of the guide sleeve 3.

Example
[0021] See also Figures 1 to 3 As shown, on the basis of the first embodiment, the utility model provides a technical solution: a lifting mechanism 6 is arranged on the inner side of the lower die base 1, and the position of the lifting mechanism 6 corresponds to the position of the forming die 16, and the lifting mechanism 6 includes a first spring 13 fixed in the lower die base 1, a lifting seat 12 is arranged on the upper side of the first spring 13, and a lifting column 11 is arranged on the upper side of the lifting seat 12, and a second spring 15 is arranged in the middle of the lower die base 1, and a pushing plate 14 is arranged at one end of the second spring 15, and the pushing plate 14 and the lifting seat 12 are fitted with each other through an inclined surface, and the pushing plate 14 is pushed by the second spring 15, and the pushing plate 14 is pushed on one side of the lifting seat 12, and cooperates with the first spring 13 to lift the lifting seat 12, thereby driving the lifting column 11 to push the molded part in the forming die 16 to be ejected.
[0022] By adopting the above technical solution, when in use, the lifting seat 12 and the inclined surface of the pushing plate 14 cooperate, and when the lifting column 11 slides down, the second spring 15 is pressed on the pushing plate 14, and cooperates with the first spring 13 to lift the lifting seat 12, so that the lifting column 11 can stably lift the stamping part formed in the forming die 16.
