Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a processing die for a camera housing. Background Art

[0002] The camera housing refers to the outer shell structure used to protect the internal components of the camera (such as lenses, image sensors, circuit boards, etc.). For some metal camera housings with simple shapes (such as some housings with thin metal sheets as the main structure), a stamping process can be used. The stamping die is installed on the stamping machine, and the metal sheet is placed between the dies. Through the up and down movement of the stamping machine, the die is used to punch, bend, stretch and other operations on the sheet to gradually form the shape of the camera housing.

[0003] A stamping die generally consists of two dies. When the two dies are closed, the blank is placed in the die cavity for forming. When the two dies are separated, the stamped product is taken out. When demolding after the stamping process is completed, tools are usually used for demolding or manual material removal. However, it is very inconvenient to remove the stamped product from the cavity, resulting in extremely low demolding efficiency. Therefore, a processing die for a camera housing is proposed to address the above problems. Utility Model Content

[0035] Example 2

[0036] For comparison with Example 1, please refer to Figure 5 As shown, the utility model provides another embodiment, the demoulding column 83 includes an upper column 831 and a lower column 832, and a screw 833 is rotatably connected to the top center of the lower column 832. The top end of the screw 833 passes through and is threadedly connected to the upper column 831, and a sliding groove 9 is opened on the side wall of the cavity 7.

[0041] Specifically, the support block 10 is used to support the rotating rod 11, the rotating rod 11 is used to drive the bevel gear 2 836 to rotate, the bevel gear 2 836 is used to drive the bevel gear 1 835 to rotate, the bevel gear 1 835 is used to drive the screw 833 to rotate, and the rotation of the screw 833 is used to drive the upper column 831 to rise and fall.

[0042] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected to be electrically connected to the hydraulic rod 5 according to actual conditions to meet control requirements. For specific connections and control sequences, reference should be made to the following working principle, in which the electrical components are electrically connected in a sequential working order. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principles and processes, and does not explain the electrical control.

[0043] Working principle: the blank is placed in the female die of the lower stamping die 2, and the hydraulic rod 5 is operated to drive the upper stamping die 1 to move downward to close the die. The blank is punched into the camera housing by closing the male die and the female die. When the mounting seat 6 moves downward, it drives the column 89 to be inserted into the cavity 7 until the connector 84 is against the base 3. When the connector 84 passes through the fixed seat 86, the inner rod of the spring telescopic rod 87 slides and contracts along the connector 84 until it stretches and inserts into the slot 85 when it faces the slot 85, thereby connecting the base 3 with the column 89. , and when the column 89 rises, it drives the base 3 to rise, so that the demoulding column 83 pushes the camera housing out of the opening 81 to achieve automatic demoulding. When the column 89 rises, it drives the base 3 to rise, and the telescopic rod 88 rotates upward to first contract and then extend. When it extends to the maximum extent, the spring telescopic rod 87 is pulled to contract through the connecting member 12, so that the inner rod of the spring telescopic rod 87 exits the slot 85, thereby canceling the connection between the base 3 and the column 89, so that the column 89 can be normally moved out of the base 3, so that it can be reused.

[0044] After replacing the stamping die, the bottom height of the groove will be adjusted accordingly due to the different sizes of the camera products. By rotating the screw 833, the upper column 831 can be driven up and down, thereby adjusting the height of the top of the demoulding column 83 according to the height of the bottom of the groove, so that the top of the demoulding column 83 and the bottom of the groove are kept on the same horizontal plane, thereby adapting to a variety of stamping dies. By rotating the rotating rod 11, the screw 833 is driven to rotate through the transmission cooperation of bevel gear 1 835 and bevel gear 2 836, which makes it convenient for the operator to adjust the height of the demoulding column 83 on the outside of the base 3.
