[0003] The following problems still exist in actual use:

[0004] (1) In the prior art, after the casting is completed, the flange workpiece needs to be demoulded manually using tools, which not only increases the labor intensity of the personnel, but also the tools are prone to scratch the flange workpiece during the demoulding process, causing damage to the flange workpiece.

[0005] (2) When the mold is used for a long time, the upper mold moves up and down continuously. After multiple movements, the movement trajectory of the upper mold is easy to deviate, affecting the processing accuracy of the workpiece. In addition, the buffering and shock absorption performance is poor, and the vibration generated during the stamping process is large, which will produce a lot of noise. Utility Model Content

[0025] By providing an ejector assembly 3, after the flange is formed inside the mold, the flange can be ejected from the lower mold 2, which is convenient for mold removal and replacement. At the same time, the ejector rod assembly 4 can play a buffering role when ejecting the flange, thereby protecting the flange from scratches.

[0026] See also Figure 1 to Figure 2, the sleeve 301 is fixedly connected to the inner bottom of the base 1, the slide bar 302 is slidably connected to the sleeve 301, the mounting plate 303 is fixedly connected to the inner bottom of the base 1, both ends of the transmission rod 304 are rotatably connected to the mounting plate 303, the gear 305 is fixedly connected to the surface of the transmission rod 304, and the gear 305 and the slide bar 302 are meshed with each other, the driving motor 306 is fixedly connected to one of the mounting plates 303, and the output shaft is fixedly connected to one end of the transmission rod 304;

[0027] When demoulding is required, the drive motor 306 is started to drive the transmission rod 304 to rotate, and at the same time drives the gear 305 to rotate. The gear 305 drives the slide rod 302 to move upward, thereby driving the ejector rod 401 to move upward, gradually applying supporting force to the flange to eject the flange.

[0028] See also Figures 2 to 3 The ejector rod assembly 4 includes an ejector rod 401, a buffer spring 402, and a limit slider 403. The top of the slide bar 302 is slidably connected to the ejector rod 401, the bottom end of the ejector rod 401 is fixedly connected to the buffer spring 402, and both sides of the bottom of the ejector rod 401 are fixedly connected to the limit slider 403. The top of the ejector rod 401 is located at the inner wall of the lower mold 2, and the bottom end of the buffer spring 402 is fixedly connected to the inner wall of the slide bar 302.

[0029] When the push rod 401 pushes out of the flange, the push rod 401 moves downward under the influence of the flange gravity to squeeze the buffer spring 402, so that the buffer spring 402 is compressed under pressure. The compression deformation of the buffer spring 402 can play a buffering role and protect the flange from scratches.

[0030] See also Figure 1 and Figure 4 , gas rods 5 are fixedly installed at the four corners of the upper surface of the base 1, the output shaft of the gas rod 5 is fixedly connected to the top plate 6, the upper mold 7 is fixedly connected to the bottom side of the top plate 6, and buffer positioning components 8 are arranged on both sides of the lower mold 2 and the upper mold 7.

The two side surfaces of the lower mold 2 are fixedly connected with the positioning blocks 801, the upper surface of the positioning block 801 is provided with a positioning groove 802, and the inner bottom of the positioning groove 802 is provided with a buffer pad 803. The two side surfaces of the upper mold 7 are fixedly connected with positioning rods 804, the positioning rods 804 are consistent with the model of the positioning groove 802, and the material of the buffer pad 803 is rubber;

[0031] During the mold closing process, the positioning rod 804 enters the positioning groove 802 to ensure that the upper mold 7 and the lower mold 2 are accurately positioned relative to each other, and when the positioning rod 804 enters the buffer pad 803 and the bottom hits the buffer pad 803, the impact force can be absorbed by the buffer pad 803 to achieve a buffering effect and reduce the noise generated.

[0032] In the utility model, the working steps of the device are as follows:

[0033] The first step: when the flange inside the mold is formed and needs to be demoulded, the driving motor 306 is started to drive the transmission rod 304 to rotate, and the gear 305 is driven to rotate at the same time. The gear 305 drives the slide bar 302 to move upward, thereby driving the ejector rod 401 to move upward, gradually applying a supporting force to the flange to eject the flange. When the ejector rod 401 ejects the flange, the ejector rod 401 moves downward under the influence of the gravity of the flange to squeeze the buffer spring 402, so that the buffer spring 402 is compressed by pressure. The compression deformation of the buffer spring 402 can play a buffering role, which can protect the flange from scratches, and when the ejector rod 401 moves, it can drive the limit slider 403 to move to limit the ejector rod 401;

[0034] The second step: during the mold closing process, when the upper mold 7 moves toward the lower mold 2, it can drive the positioning rod 804 to move downward, and drive the positioning rod 804 to enter the positioning groove 802, which can ensure that the upper mold 7 and the lower mold 2 are accurately positioned relative to each other, and when the positioning rod 804 enters the buffer pad 803 and the bottom hits the buffer pad 803, the impact force can be absorbed by the buffer pad 803, which has a buffering effect and reduces the noise generated.
