The demoulding device includes a workbench 1 and a molding mold 2 for molding the headlamp lampshade installed on the workbench 1. The workbench 1 is provided with a protective frame 3, and the protective frame 3 is provided with an upper mold 4 used in conjunction with the molding mold 2.

The protective frame 3 is provided with a demoulding mechanism 6 for demoulding the molded lampshade inside the upper mold 4. The demoulding mechanism 6 includes a connecting pipe sleeve 61 provided on the protective frame 3, and a connecting pipe sleeve 64 connected to the connecting pipe sleeve 61 through an air inlet pipe 64. The connecting sleeve 61 is provided with an air intake pump 63 for communicating with the upper mold 4, the interior of the connecting sleeve 61 is provided with an air intake component 62 for air intake into the internal cavity of the upper mold 4, and the connecting sleeve 61 is provided with a connecting component 65 for maintaining communication with the interior of the upper mold 4, the bottom of the upper mold 4 is provided with a long rod 67, and the long rod 67 is provided with a movable ejector plate 68, and the workbench 1 is provided with an ejector sleeve 66 for demoulding the molded lampshade adhered to the molding mold 2, and the inner diameter of the ejector sleeve 66 matches the outer shape of the molding mold. The upper mold 4 is equipped with a plurality of molds, and the ...

[0023] The demoulding mechanism 6 solves the problem of smooth demoulding of the injection molded part by inputting nitrogen. However, when the demoulding operation is not performed, nitrogen will continue to be input, which is easy to cause certain waste and has poor practicality. Therefore, an air intake component 62 is provided. The air intake component 62 includes a rotatable top plate 622 arranged inside the connecting sleeve 61, and a servo motor 621 arranged on the connecting sleeve 61 for driving the top plate 622. A movable slider 623 is arranged inside the connecting sleeve 61, and a connecting rod 626 is arranged on the slider 623, and a fixed The fixed sleeve 625 inside the connecting sleeve 61, the spring 624 between the slider 623 and the fixed sleeve 625, and the connecting rod 626 are provided with a baffle 629, a retaining ring 627 is provided between the fixed sleeve 625 and the baffle 629, and a sealing gasket 628 is provided on the baffle 629. The input end of the firstly arranged air intake pump 63 is connected with nitrogen. When nitrogen input is required, the air intake pump 63 is started to drive nitrogen into the inside of the connecting sleeve 61, and the servo motor 621 is started to drive the top plate 622 to rotate clockwise. When the top plate 622 rotates clockwise, the top plate 622 rotates clockwise. When the raised part of the plate 622 rotates to the bottom, the servo motor 621 is stopped, and the slider 623 is driven to move downward, so that the spring 624 is compressed, and the baffle 629 is driven to move downward, so that the baffle 629 is separated from the retaining ring 627. Since the outer diameter of the baffle 629 is smaller than the inner diameter of the connecting pipe sleeve 61, the nitrogen will pass through the retaining ring 627 and flow downward from the outer side of the baffle 629, and finally enter the inner cavity of the upper mold 4 through the injection port 654. Through the continuous input of nitrogen, the adhered internal part of the upper mold 4 can be The injection molded part is ejected. When nitrogen input is not needed, the servo motor 621 is started again to rotate the top plate 622 clockwise. When the raised portion of the top plate 622 rotates to the top, the servo motor 621 is stopped. At this time, under the action of the spring 624, the baffle 629 is driven to move upward, so that the baffle 629 contacts the retaining ring 627. A sealing gasket 628 is provided on the baffle 629 to ensure the sealing between the retaining ring 627 and the baffle 629, so that nitrogen cannot be input downward, so that nitrogen will not be wasted, and better practicality is achieved.

[0024] Example 2

[0025] Based on Example 1, Figure 1-Figure 4As shown, based on the current problem that the injection molded part can be smoothly removed from the mold by the input of nitrogen, there is still a problem that the connection between the cavity and the gas supply is not stable enough, which is easy to cause gas leakage and affect the demoulding effect. Therefore, the device is also provided with a connecting component 65, the connecting component 65 includes an upper connecting sleeve 651 fixed on the connecting pipe sleeve 61, and a lower connecting sleeve 655 fixed on the upper mold 4 and used in conjunction with the upper connecting sleeve 651, the inner sleeve of the lower connecting sleeve 655 is provided with an injection port 654 communicated with the interior of the upper mold 4, the inner wall of the upper connecting sleeve 651 is provided with a sealing sleeve 652, the upper connecting sleeve 651 is communicated with the connecting pipe sleeve 61, the inner diameter of the upper connecting sleeve 651 matches the outer diameter of the injection port 654, and the outer diameter of the upper connecting sleeve 651 matches the outer diameter of the lower connecting sleeve 655, the upper connecting sleeve 651 is provided with a plurality of connecting holes 653, and the lower connecting sleeve The sleeve 655 is provided with a plurality of limiting rods 656 used in conjunction with the connecting holes 653. The upper mold 4 is continuously raised by the cylinder 5, which will make the injection port 654 slide into the upper connecting sleeve 651. A sealing sleeve 652 is provided on the inner wall of the upper connecting sleeve 651. The lower end of the sealing sleeve 652 is arc-shaped, which is convenient for the upper connecting sleeve 651 to smoothly cover the injection port 654. In the covering process, the sealing sleeve 652 will be continuously compressed to ensure the air tightness between the upper connecting sleeve 651 and the injection port 654. At the same time, the connecting holes 653 will gradually cover the limiting rods 656 to achieve better connectivity. At this time, the interior of the connecting pipe sleeve 61 will be connected to the inner cavity of the upper mold 4 through the injection port 654. At the same time, before starting the air intake pump 63 to supply air to the inner cavity of the upper mold 4, it is necessary to ensure that the upper connecting sleeve 651 and the injection port 654 are connected, thereby achieving a better demoulding effect.
