Description

Technical Field

[0001] The utility model relates to the technical field of demoulding devices, in particular to a demoulding device for die-casting housings of LED lamps. Background Art

[0002] The die-cast housing of LED lamps is a lamp shell made by die-casting process. The die-cast housing of LED lamps is usually made of aluminum alloy or zinc alloy materials. It has the advantages of high strength, corrosion resistance and wear resistance. At the same time, it has good thermal conductivity, which can effectively dissipate heat and increase the service life of LED lamps. During the die-casting process of the LED lamp shell, liquid metal is injected into the mold for molding, and a solid shell is formed after cooling. A demoulding device is required to smoothly remove the solid shell from the mold to ensure that the shape and size of the shell are accurate.

[0003] However, in the prior art, when the die-casting mold is used to produce the shell of the LED lamp, after the metal solution cools down, the upper mold is opened, and then the molded LED lamp shell is lifted up by the demolding push rod provided at the bottom of the lower mold to complete the demolding operation. Such a demolding method has a simple structure and a low cost, and is a demolding structure commonly used in casting processing. However, when such a demolding structure is used to demold the shell of the LED lamp, due to the thin thickness of the shell of the LED lamp, when the demolding push rod pushes it, the contact area between the push rod and the shell of the LED lamp is small, resulting in excessive pressure on the contact surface of the LED lamp shell, which can easily cause dents on the surface of the LED lamp shell, affecting the quality of the LED lamp shell.

The upper part of the No. 2 fixed plate 210 is fixedly connected to the No. 2 slide rail 211, and the No. 2 slider 212 is slidably connected inside the No. 2 slide rail 211. The No. 2 slide rail 211 is fixedly connected to the No. 2 slide rail 213. One end of the telescopic rod 213 is fixedly connected to the side of the No. 2 slider 212. A spring 214 is provided on the surface of the telescopic rod 213. One end of the spring 214 is fixedly connected to the No. 2 slide rail 211, and the other end of the spring 214 is fixedly connected to the No. 2 slider 212.

The side of the driven wedge push block 27 is fixedly connected to a connecting frame 28, and one end of the connecting frame 28 is fixedly connected to a wedge push plate 29.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. The upper mold 11 and the lower mold 12 are fitted together, and molten metal is injected into the upper mold 11 and the lower mold 12. When the LED lamp housing is cooled and formed, the upper mold 11 is opened, and then the servo motor 24 drives the adjusting screw 25 to rotate, so that the active wedge push block 26 moves upward along the adjusting screw 25. As the active wedge push block 26 moves upward, the telescopic rod 213 and the spring 214 push the second slider 212 to slide along the second slide rail 211. In the process of the movement of the second slider 212, the driven wedge push block 27 and the connecting frame 2 are driven. 8. The wedge-shaped push plate 29 moves along the surface of the lower mold 12, and the edge of the LED lamp housing on the surface of the lower mold 12 is lifted by the wedge-shaped push plate 29, thereby reducing the adhesion between the LED lamp housing and the surface of the lower mold 12, and then the connecting plate 15 is driven by the electro-hydraulic push rod 17 to move, and the connecting plate 15 drives the demoulding push rod 16 to push the LED lamp housing. The wedge-shaped push plate 29 is first used to reduce the adhesion between the LED lamp housing and the lower mold 12, so as to avoid excessive force on the surface of the LED lamp housing when the demoulding push rod 16 demoulds the LED lamp housing, thereby improving the processing quality of the LED lamp housing.

[0025] like Figure 2 and Figure 3 As shown, a mounting bracket 13 is fixedly connected to one side of the lower mold 12, and an electro-hydraulic push rod 17 is fixedly connected to the surface of the lower mold 12. One end of the electro-hydraulic push rod 17 is fixedly connected to a connecting plate 15. The mounting bracket 13 facilitates the installation of the entire assembly on the surface of the die-casting equipment, and the electro-hydraulic push rod 17 facilitates the stable movement of the connecting plate 15.

The limiting rod 14 limits the connecting plate 15 to improve the stability of the connecting plate 15 when it moves.

[0028] like Figure 4 As shown, the adjusting screw rod 25 is located in the middle of the active wedge-shaped push block 26 , and the adjusting screw rod 25 passes through the active wedge-shaped push block 26 , so that the height of the active wedge-shaped push block 26 can be adjusted easily by adjusting the screw rod 25 .

[0029] like Figure 1As shown, the side of the No. 1 fixed plate 21 is fixedly connected to the No. 1 slide rail 22, and the No. 1 slide rail 22 is slidably connected inside the No. 1 slide block 23. The No. 1 slide block 23 is fixedly connected to the side of the active wedge-shaped push block 26. During the up and down movement of the active wedge-shaped push block 26, the No. 1 slide block 23 slides along the No. 1 slide rail 22 to limit the movement of the active wedge-shaped push block 26, thereby improving the stability of the active wedge-shaped push block 26 during movement.

[0030] like Figure 4 As shown, two wedge-shaped push plates 29 are provided on the side of the lower mold 12 , and the two wedge-shaped push plates 29 are symmetrically distributed on both sides of the lower mold 12 . The LED lamp housing can be fully demoulded through the two wedge-shaped push plates 29 .

[0031] The usage and working principle of this device are as follows: the upper mold 11 and the lower mold 12 are fitted together, and molten metal is injected into the upper mold 11 and the lower mold 12. When the LED lamp housing is cooled and formed, the upper mold 11 is opened, and then the servo motor 24 drives the adjusting screw 25 to rotate, so that the active wedge push block 26 moves upward along the adjusting screw 25. As the active wedge push block 26 moves upward, the telescopic rod 213 and the spring 214 push the No. 2 slider 212 to slide along the No. 2 slide rail 211. During the movement of the No. 2 slider 212, the driven wedge push block 27, the connecting frame 28, and the wedge push plate 29 are driven to move along the surface of the lower mold 12. Then, the connecting plate 15 is driven to move by the electro-hydraulic push rod 17, and the connecting plate 15 drives the demoulding push rod 16 to push the LED lamp housing. During the up and down movement of the active wedge push block 26, the No. 1 slider 23 slides along the No. 1 slide rail 22.
