Description

Technical Field

[0001] The utility model relates to the technical field of cold stamping, in particular to a demoulding mechanism of a cold stamping die. Background Art

[0002] Cold stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material to cause it to separate or plastically deform, thereby obtaining the required parts.

[0003] After the cold stamping die is formed, the body is subjected to a certain impact, causing its bottom to fit into the die groove, making it difficult to completely separate during demolding, and easily resulting in the production of defective products. At the same time, when forming different workpieces, the size of the die groove is difficult to change, and the upper and lower molds need to be replaced uniformly, resulting in poor compatibility. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a demolding mechanism for a cold stamping die, which has the advantages of driving a push plate to push the bottom end of the inside of the die groove through a telescopic rod, thereby ejecting the die inside the die groove, making demolding more convenient, while maintaining the stability of the push plate in moving upward or resetting, and facilitating the extrusion and adjustment of the space inside the die groove, making it suitable for processing molds of different sizes, improving the compatibility of the device, etc., and solving the above-mentioned technical problems.

[0008] Preferably, four groups of support rods are relatively fixedly installed on the top of the base, and a sleeve rod is sleeved inside each group of support rods, and the top end of the sleeve rod is fixedly connected to the bottom end of the mold groove.

[0009] Through the above technical solution, firstly, the bottom end of the mold groove is connected with the base through four groups of support rods and sleeve rods to provide supporting force and increase the stability of the bottom end of the mold groove.

[0010] Preferably, a group of push plates are fixedly mounted on the top of the telescopic rod.

[0011] Through the above technical solution, when the mold processing inside the mold groove is completed, the telescopic rod is started to extend the top of the telescopic rod to drive the push plate to extend, and the push plate ejects the workpiece at the bottom end of the mold groove, thereby facilitating demoulding.

[0013] Through the above technical solution, while the telescopic rod drives the push plate upward, the push plate drives the fixed cylinder on the outer circumference of the vertical pole upward synchronously, and drives the spring to stretch at the same time, thereby increasing the stability of the push plate upward. When the telescopic rod is reset, it drives the spring to reset synchronously, and drives the fixed cylinder to reset synchronously on the outer circumference of the vertical pole, thereby maintaining stability when resetting the push plate, and avoiding the offset of the support plate and the bottom end of the mold groove during resetting or upward movement, resulting in unevenness inside the mold groove.

[0014] Preferably, the connecting frames are arranged in two groups relatively to each other, and two groups of threaded rods are installed through the threads on the sides relatively to each other, and the outer peripheral surface of the movable plate is slidably connected to the inner wall of the slide groove.

[0015] Through the above technical solution, the threaded rod is rotated to make the threaded rod move relative to the thread on the side of the connecting frame, and the corresponding bearing drives the movable plate to drive the limiting side plate to slide inside the slide groove, thereby limiting the two sides of the mold groove, making it easy to adjust the internal size of the mold groove, so that it is suitable for processing molds of different models and sizes.

[0016] Compared with the prior art, the utility model provides a demoulding mechanism for a cold stamping die, which has the following beneficial effects:

When the telescopic rod drives the push plate upward, the push plate drives the fixed tube on the outer circumference of the vertical rod to move upward synchronously, and drives the spring to stretch at the same time, thereby increasing the stability of the push plate upward. When the telescopic rod is reset, it drives the spring to reset synchronously, and drives the fixed tube to reset synchronously on the outer circumference of the vertical rod, thereby maintaining stability for the reset of the push plate, and avoiding the deviation of the support plate and the bottom end of the mold groove during reset or upward movement, resulting in unevenness inside the mold groove.

[0027] Specifically, four groups of support rods 2 are relatively fixedly installed at the top of the base 1, and a sleeve rod 3 is sleeved inside each group of support rods 2, and the top of the sleeve rod 3 is fixedly connected to the bottom of the mold groove 4. The advantage is that firstly, the bottom of the mold groove 4 is connected to the base 1 through the four groups of support rods 2 and the sleeve rod 3, providing support force and increasing the stability of the bottom of the mold groove 4.

[0028] Specifically, a set of push plates 6 are fixedly mounted on the top of the telescopic rod 5. The advantage is that when the mold inside the mold cavity 4 is processed, the telescopic rod 5 is started to extend the top of the telescopic rod 5 to drive the push plate 6 to extend, and the push plate 6 ejects the workpiece at the bottom end of the mold cavity 4, thereby facilitating demoulding.

[0029] Specifically, two groups of fixed cylinders 7 are relatively fixedly installed at the bottom end of the push plate 6, the outer circumference of the vertical rod 8 is slidably connected to the inside of the fixed cylinder 7, and the top end is fixedly connected to the top end of the base 1. Two groups of springs 9 are provided, and the top end is fixedly connected to the bottom end of the push plate 6, and the bottom end of the spring 9 is fixedly connected to the top end of the base 1. The advantage is that when the telescopic rod 5 drives the push plate 6 upward, the push plate 6 drives the fixed cylinder 7 to move upward synchronously on the outer circumference of the vertical rod 8, and at the same time drives the spring 9 to stretch, which increases the stability of the push plate 6 upward.
