[0024] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0025] A cold forging camera housing processing mold includes a lower mold assembly 2, a core 3, and an upper mold assembly 1. The upper mold assembly 1 is used to apply forging pressure downwards. The core 3 extends longitudinally and is connected to the lower mold assembly 2 at its lower part. The upper part of the core 3 extends above the lower mold assembly 2 to form a core head, which is used to place the workpiece to be cold forged. The upper mold assembly 1 includes a forging pressure plate 11 and a forging stationary plate 12. The forging pressure plate 11 and the forging stationary plate 12 are stacked and assembled. The forging stationary plate 12 has a forging stationary groove, and the workpiece to be cold forged is placed in the forging stationary groove. The forging pressure plate 11 is used to apply forging pressure to the workpiece to be cold forged.

[0026] The aforementioned cold forging camera housing processing mold, during processing, uses a fixed part head to feed the product. Under the cooperation of the forging plate 11 and the forging plate 12, the material to be cold forged is cold forged, and finally the camera housing 5 is produced. In this way, the cold forging method for manufacturing the camera housing 5 not only improves the production efficiency of the camera housing 5, but also reduces the production cost of the camera housing 5, and helps to increase the strength and precision of the camera housing 5, greatly improving the quality and service life of the product.

[0027] The lower mold assembly 2 includes an upper core plate 21 and a lower core plate 22, which are stacked and assembled. The component core 3 forms a limiting component, which is embedded in the lower core plate 22. The limiting component is used to restrict the component core 3 from moving in the direction toward the lower core plate 22.

[0028] In this way, the combined action of the upper core plate 21 and the lower core plate 22 improves the stability of the core 3 and ensures the alignment of the loaded product, thereby improving the accuracy of cold forging.

[0029] The limiting component includes an outer edge, which is arranged to surround the core 3 and is flat. An upper core plate 21 is embedded in the outer edge, and the outer edge and the lower core plate 22 are arranged to overlap and abut against each other. In this way, under the action of the limiting component, the core 3 is prevented from being pressed down and falling out of position, ensuring that the core 3 is set in place and also ensuring the manufacturing accuracy of the camera housing 5.

[0030] The lower die assembly 2 includes multiple pressure-bearing blocks 23, which are arranged in a long strip shape. Each pressure-bearing block 23 is arranged in a corresponding manner around the upper core plate 21. The thickness of the pressure-bearing block 23 is greater than the thickness of the upper core plate 21. The pressure-bearing blocks 23 are used to bear the downward pressure of the upper die assembly 1. During cold forging, under the action of each pressure-bearing block 23, the pressure of the upper die assembly 1 is borne, preventing the upper die assembly 1 from continuing to apply downward pressure to the core 3, and preventing the core 3 from being subjected to excessive force, thereby ensuring the reciprocating cold forging process of the die.

[0031] The end of the fixed head forms a forging head, which is used to receive the forging pressure applied by the upper core plate 21 and to apply the forging pressure to the workpiece to be cold-forged. In this way, the cold forging operation is carried out in conjunction with the forging head, so that the camera housing 5 meets the expected design requirements and effectively improves the strength and precision of the camera housing 5.

[0032] The lower mold assembly 2 includes a core plate 24, which is arranged horizontally. The lower part of the core 3 is mated and fixedly arranged with the core plate 24. Under the action of the core plate 24, the core 3 is assembled.

[0033] The lower mold assembly 2 includes a reinforcing plate 25, a lower core plate 22, and the reinforcing plate 25 and the core plate 24 are arranged in a sequentially stacked arrangement. The reinforcing plate 25 has a fixing groove, and the lower part of the core 3 forms a core seat. The core seat is located in the fixing groove, and the outer surface of the core seat is in contact with the groove wall of the fixing groove.

[0034] In this way, the stability of the core 3 is improved by the reinforcing plate 25. At the same time, the fixing groove provides space for the core 3 to move and plays a positioning and guiding role in the movement of the core 3, thereby improving the accuracy of cold forging.

[0035] The lower mold assembly 2 includes multiple ejector pins 4, which are arranged at intervals and corresponding to each other. The ejector pins 4 are arranged in a corresponding manner with the core seat. Each ejector pin 4 is used to apply ejection force to the core seat. Under the action of each ejector pin 4, it is convenient for the core 3 to move and be demolded.

[0036] The core 3 includes an upper core 31, a lower core 32, and a core shell 33. The upper part of the upper core 31 forms a core head, and the lower part of the upper core 31 is fitted with the core shell 33. The upper part of the lower core 32 is fitted with the core shell 33, and the lower part of the lower core 32 is fitted with a core fixing plate. The lower core 32 and the core fixing plate are assembled together. The lower part of the core shell 33 forms a core seat. The ejector pin 4 is used to apply ejection force to separate the lower core 32 from the core shell 33. In this way, the lower core 32 and the core shell 33 can be demolded, which facilitates the replacement of parts such as the upper core 31, the lower core 32, and the core shell 33, and also facilitates the demolding between the upper seat plate 26 and the core fixing plate 24.

[0037] The lower mold assembly 2 includes four ejector pins 4, which are arranged in a circular and spaced manner, and are symmetrically arranged in pairs; this improves the uniformity of the ejection force and the smoothness of demolding.

[0038] The lower mold assembly 2 includes an upper base plate 26, a middle base plate 27, and a lower base plate. The upper base plate 26, the middle base plate 27, and the lower base plate are stacked and assembled in sequence. The ejector pin 4 extends through the upper base plate 26 and the middle base plate 27 in sequence and is arranged to dock with the lower base plate. This realizes the setting of the ejector pin 4 and also realizes the support of the upper mold assembly 1.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
