However, there are many burrs on the surface of the processed automobile parts, and the burrs are relatively sharp. When the workers take the processed automobile parts out of the lower mold, the burrs on the surface of the automobile parts will The burrs on the processed auto parts can be removed by adjusting device 2 to avoid the burrs on the workers' hands.

The screw rod 207 is a titanium alloy rod. The surface of the rod body of the titanium alloy screw rod 207 is relatively hard. This is also why the surface of the screw rod 207 is difficult to deform when the screw rod 207 is used for a long time, and the service life is relatively strong;

[0033] In the embodiments of the present invention, please refer to Figure 5 The auxiliary device 3 includes a fixed block 31, which is fixedly connected to the upper die seat 6. The inner wall of the fixed block 31 is fixedly connected to a fixed rod 32. The arc surface of the fixed rod 32 is rotatably connected to a power rod 34. Both ends of the arc surface of the fixed rod 32 are sleeved with coil springs 33. The two ends of the coil spring 33 are respectively fixedly connected to the power rod 34 and the fixed block 31. An impact block 35 is installed at one end of the power rod 34 away from the fixed rod 32. When the upper die seat 6 and the lower die seat 4 are used to cooperate to produce automobile parts, some of the produced automobile parts will be stuck in the upper die seat 6 and are difficult to take out. At this time, the upper die seat 6 can be impacted by the auxiliary device 3, so that the workers can use the auxiliary device 3 to quickly take out the automobile parts stuck in the upper die seat 6. The arc surface of the power rod 34 is provided with a coil spring 33. The two ends of the coil spring 33 are respectively fixedly connected to the power rod 34 and the fixed block 31. The arc surface is fixedly connected with a sleeve 36, and the arc surface of the sleeve 36 is fixedly connected with a pull ring 37. When the power rod 34 needs to be pulled, the pull ring 37 installed on the sleeve 36 can be used to pull the power rod 34. The pull ring 37 can improve the speed and efficiency of pulling the power rod 34. The end of the arc surface of the impact block 35 close to the power rod 34 is fixedly connected with two connecting blocks 38. The inner walls of the two connecting blocks 38 are slidably penetrated by the same limiting rod 39. The limiting rod 39 slides through the inner wall of the power rod 34. When the impact block 35 is damaged after long-term use, the limiting rod 39 can be pulled out from the inner wall of the connecting block 38 to replace the damaged impact block 35, so that the impact effect of the impact block 35 can be improved by replacing the new impact block 35.

[0034] The working principle of a plastic mold for automobile parts processing provided by the utility model is as follows: when it is necessary to scrape off the burrs on the surface of the processed automobile parts, firstly, the fixing plate 201 is installed on the lower mold base 4 by using screws, and then the motor 205 is started. The movement of the motor 205 will drive the screw rod 207 to rotate through its output end. When the screw rod 207 rotates, it will drive the adjustment block 206 to slide in the adjustment plate 204, so that the adjustment block 206 can slide in the adjustment plate 204 to drive the scraper 208 installed on the side of the adjustment block 206 to move, so that the scraper 208 can be moved to scrape off the burrs on the surface of the automobile parts, thereby preventing the burrs from stabbing the hands of workers. The situation occurs that the surface of the motor 205 is relatively fragile. At this time, the protective shell 209 can be used to protect the surface of the motor 205, so as to avoid the motor 205 from being damaged when it is bumped. The protective shell 209 can increase the service life of the motor 205. When the protective shell 209 protects the motor 205, the heat dissipation holes 210 opened on the protective shell 209 can discharge the heat energy generated by the motor 205 when it is working, so that the heat energy generated by the motor 205 when it is working can be reduced through the heat dissipation holes 210, and the loss of heat energy to the motor 205 is reduced. The surface of the rod body of the titanium alloy screw rod 207 is relatively hard, which is also why the surface of the screw rod 207 is less likely to deform when the screw rod 207 is used for a long time, and the service life is longer.

[0035] When it is necessary to remove the automobile parts stuck in the upper die seat 6, the power rod 34 is pulled in the direction away from the upper die seat 6. The power rod 34 will rotate on the surface of the fixed rod 32. When the power rod 34 rotates, it will drive the two coil springs 33 to reel in. At this time, the coil springs 33 are in a stretched state. After the power rod 34 is pulled to a certain distance, the power rod 34 is released. The coil spring 33 is restored and drives the impact block 35 to collide with the upper die seat 6 through the power rod 34, so that the upper die seat can be hit by the impact block 35. 6, to knock out the automobile parts stuck in the upper die seat 6. When it is necessary to pull the power rod 34, the pull ring 37 installed on the sleeve 36 can be used to pull the power rod 34. The pull ring 37 can improve the speed and efficiency of pulling the power rod 34. When the impact block 35 is damaged after long-term use, the limit rod 39 can be pulled out from the inner wall of the connecting block 38 to replace the damaged impact block 35, so that the impact effect of the impact block 35 can be improved by replacing the new impact block 35.

[0036] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
