Technical Field

[0001] The utility model relates to the technical field of stamping dies, and specifically relates to a stamping die with automatic demoulding. Background Technique

[0002] A stamping die with automatic demoulding is a device that can automatically eject the stamped parts from the die during the stamping process. It is widely used in multiple fields such as automobiles, household appliances, electronics, communications, and hardware. Especially in mass production, the stamping die with automatic demoulding can significantly improve production efficiency and product quality, and reduce production costs. When the stamping die with automatic demoulding is in use, the resilience of a spring is usually utilized to enable the stamped parts to be ejected after stamping. However, the spring will age and corrode after long-term use, resulting in poor resilience and inability to eject the stamped parts. At this time, replacing the spring increases the cost, and there are certain deficiencies. Therefore, we propose a stamping die with automatic demoulding. Content of the Utility Model

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0027] Some embodiments of the present utility model will be described below with reference to the accompanying drawings to provide a stamping die with automatic demoulding.

[0028] Embodiment 1:

[0029] Referring to Figure 1-7 , this is the first embodiment of the present utility model. This embodiment provides a stamping die with automatic demoulding, including a lower die base 100, a guide pillar 200, an upper die base 300, a lower ejection assembly 400, an adjusting part 500, a blocking part 600 and an upper ejection assembly 700.

[0030] Specifically, the guide pillar 200 is arranged at the corners of the top end of the lower die base 100. During use, the guide pillar 200 plays a positioning role, which can ensure the precise docking of the upper die base 300 with the lower die base 100.

[0031] Specifically, the upper die base 300 is inserted and connected with the guide pillar 200. During use, a hydraulic cylinder can be connected to the top end of the upper die base 300, and the upper die base 300 can be driven to move downward by the hydraulic cylinder for stamping.

[0032] Specifically, the lower ejecting component 400 is disposed on the lower die base 100. The lower ejecting component 400 includes a bracket 401 bolted to the bottom of the lower die base 100, an ejecting rod 402 inserted through the bracket 401, a first spring 403 disposed on the ejecting rod 402, and a fixing plate 404 disposed at the bottom of the first spring 403. A round hole is formed in the middle position of the fixing plate 404. During use, the bracket 401 is fixed by bolts for easy installation and disassembly of the lower ejecting component 400. Then, the ejecting rod 402 can move downward through the first spring 403 for stamping. At the same time, the resilience of the first spring 403 is utilized to facilitate the ejection of the stamped part.

[0033] Specifically, the adjusting component 500 includes a clamping seat 501 inserted through the lower ejecting component 400, a stud 502 disposed on the right side of the clamping seat 501, and a fastening knob 503 threadedly connected to the stud 502. During use, when the resilience of the first spring 403 is poor, the ejecting rod 402 will move downward. At this time, the ejecting rod 402 cannot completely eject the stamped part. The user can loosen the fastening knob 503 of the adjusting component 500. After loosening, the clamping seat 501 can be moved upward. The moving clamping seat 501 will drive the fixing plate 404, the first spring 403, and the ejecting rod 402 until the top end of the ejecting rod 402 is at the same horizontal plane as the top end of the lower die base 100. Then, the fastening knob 503 is tightened to avoid the problem that the ejecting rod 402 cannot completely eject the stamped part due to the poor resilience of the first spring 403.

[0034] Specifically, the blocking component 600 is disposed at the bottom of the lower die base 100. The blocking component 600 includes a baffle 601 screwed to the bottom of the lower die base 100 and an anti-wear ring 602 bonded to the top end of the baffle 601. The aperture of the middle round hole of the baffle 601 is smaller than the aperture of the middle round hole of the lower die base 100. During use, the blocking component 600 can be fixed by screws for easy installation and disassembly of the blocking component 600. Then, through the blocking of the anti-wear ring 602, the ejecting rod 402 can be prevented from moving downward continuously for stamping.

[0035] Specifically, the upper ejecting component 700 includes a mounting plate 701 screwed to the top end of the upper die base 300, an air pipe 702 disposed on the top of the mounting plate 701, a second spring 703 disposed at the bottom of the mounting plate 701, an ejecting seat 704 disposed at the bottom of the second spring 703, and an air hole 705 formed in the ejecting seat 704.

[0036] An installation hole 301 for installing the upper ejecting component 700 is provided at the middle position of the upper die base 300, and the installation hole 301 is a circular hole. A plurality of air holes 705 are provided, and the plurality of air holes 705 are arranged in a circular pattern. The air pipe 702 is fixedly connected to the air supply device. During use, the elastic force of the second spring 703 can be used to eject the stamping part through the ejecting seat 704, avoiding the stamping part sticking to the upper die base 300. When the second spring 703 has poor resilience and cannot eject the stamping part, the air pipe 702 of the upper ejecting component 700 can be connected to the air supply device, and then the air supply device conveys gas. The conveyed gas can reach the installation hole 301 of the upper die base 300 through the air pipe 702 and the mounting plate 701. Subsequently, the gas is discharged through the air holes 705 of the ejecting seat 704, and the discharged gas can eject the stamping part, avoiding the problem that the stamping part cannot be ejected due to the poor resilience of the second spring 703.

[0037] The working principle and usage process of the present utility model: When the first spring 403 has poor resilience, the ejecting rod 402 will move downward. At this time, the ejecting rod 402 cannot completely eject the stamping part. The user can loosen the fastening knob 503 of the adjusting part 500. After loosening, the clamping seat 501 can be moved upward. The moving clamping seat 501 will drive the fixing plate 404, the first spring 403 and the ejecting rod 402 until the top end of the ejecting rod 402 is at the same horizontal plane as the top end of the lower die base 100. Then, tighten the fastening knob 503 to avoid the problem that the ejecting rod 402 cannot completely eject the stamping part due to the poor resilience of the first spring 403. When the second spring 703 has poor resilience and cannot eject the stamping part, the air pipe 702 of the upper ejecting component 700 can be connected to the air supply device, and then the air supply device conveys gas. The conveyed gas can reach the installation hole 301 of the upper die base 300 through the air pipe 702 and the mounting plate 701. Subsequently, the gas is discharged through the air holes 705 of the ejecting seat 704, and the discharged gas can eject the stamping part, avoiding the problem that the stamping part cannot be ejected due to the poor resilience of the second spring 703.

[0038] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
