[0037] A method for using a new energy vehicle reducer housing hand-plate mold comprises the following steps: Step 1: S1: Lubricating liquid is passed into the connecting pipe 402, and the lubricating liquid lubricates the upper mold 103 and the lower mold 104 through the nozzle 403; S2: By adjusting the connecting pipe 402 and the nozzle 403 to reciprocate in an arc shape, the upper mold 103 and the lower mold 104 are fully lubricated; Step 2: S3: The upper mold 103 is moved downward to fit with the lower mold 104, and then injection molding is performed through the liquid inlet of the lower mold 104. After the injection molding is completed and cooled, the upper mold 103 is moved upward; Step 3: S4: The formed hand plate is ejected by the ejection plate 206. When the hand plate is ejected from the lower mold 104, the rollers 313 on both sides approach the hand plate to limit the hand plate to prevent the hand plate from shifting, and then the hand plate can be taken out.

[0038] The specific scheme is as follows: start the cylinder 102 to drive the upper mold 103 to move to a suitable position, start the cylinder 202 to extend and retract, so as to drive the wedge-shaped strip 302 to move up and down, and under the joint action of the elastic member 306, the L-shaped plate 303 drives the adjustment plate 407 to move back and forth, and the adjustment plate 407 drives the L-shaped rod 404 to rotate back and forth in an arc through the adjustment slot 408 and the arc frame 406, and drives the connecting pipe 402 and the nozzle 403 to rotate back and forth in an arc to ensure that the lubricating liquid at the nozzle 403 is evenly sprayed on the upper mold 103 and the lower mold 104, so that the formed hand plate is not easy to adhere to the upper mold 103 and the lower mold 104, and the integrity of the hand plate is improved. Subsequently, the cylinder 102 is turned on to drive the upper mold 103 to fit with the lower mold 104, and injection molding is performed. After cooling, the upper mold 103 moves up, and the cylinder 202 is turned on to drive the connecting plate 203 to move. 203 drives the support plate 205 to move, and the support plate 205 drives the ejection plate 206 to move, so that the formed hand plate part can be easily and quickly ejected from the lower mold 104, thereby improving the processing efficiency. At the same time, the connecting plate 203 moves up to eject the hand plate part out of the lower mold 104, and the connecting plate 203 drives the wedge-shaped bar 302 to move up, and the wedge-shaped bar 302 pushes the L-shaped plate 303 to move horizontally, and the L-shaped plate 303 drives the moving plate 308 and the connecting column 310 to move, and the connecting column 310 drives the connecting frame 311, the rotating shaft 312 and the roller 313 to move. When the roller 313 contacts the hand plate part, the moving plate 308 squeezes the elastic member 2 309. Under the elastic force of the elastic member 2 309, the roller 313 squeezes and limits the side wall of the hand plate part, so that the outer wall of the hand plate part is not easy to be skewed and scratched against the edge of the lower mold 104, thereby ensuring the beauty of the surface of the hand plate part and improving the structural integrity and service life of the entire part.

A plurality of rollers (313) are provided, and rotating shafts (312) are rotatably mounted on the inner walls of the plurality of rollers (313), and both ends of the rotating shafts (312) are fixedly connected to the inner wall of the connecting frame (311).

8. The new energy vehicle reducer housing hand-made mold according to claim 1 is characterized in that: Fixed plates (401) are respectively fixedly mounted on the two side surfaces of the frame body (301), a plurality of connecting tubes (402) are provided, the lower end of the connecting tube (402) rotates through the bearing seat to penetrate the top surface of the fixing plate (401) and extends to the bottom of the fixing plate (401), an L-shaped rod (404) is fixedly mounted on the outer wall of the lower end of the connecting tube (402), an arc-shaped frame (406) is slidably mounted on the outer wall of the lower end of the L-shaped rod (404), and the top surface of the arc-shaped frame (406) is fixedly connected to the bottom surface of the fixing plate (401) via a fixing rod (405).

9. A new energy vehicle reducer housing hand-made mold according to claim 8, characterized in that: Adjustment plates (407) are fixedly mounted on both side surfaces of the L-shaped plate (303), a through slot (409) is provided through the side surface of the frame body (301), the side surface of the adjustment plate (407) is slidably connected to the inner wall of the through slot (409), an adjustment slot (408) is provided through the top surface of the adjustment plate (407), and the inner wall of the adjustment slot (408) is slidably connected to the outer wall of the L-shaped rod (404).

10. A method for using a new energy vehicle reducer housing hand-plate mold, applicable to a new energy vehicle reducer housing hand-plate mold as described in any one of claims 1 to 9, characterized in that: The method of using the hand plate mold includes the following steps: Step 1: S1: Lubricating liquid is introduced into the connecting pipe (402), and the lubricating liquid lubricates the upper mold (103) and the lower mold (104) through the nozzle (403); S2: adjusting the connecting pipe (402) and the nozzle (403) to reciprocate in an arc shape, thereby fully lubricating the upper mold (103) and the lower mold (104); Step 2: S3: the upper mold (103) is moved downward to fit with the lower mold (104), and then injection molding is performed through the liquid inlet of the lower mold 104. After the injection molding is completed and cooled, the upper mold (103) is moved upward; Step 3: S4: The formed hand plate is ejected through the ejection plate (206). When the hand plate is ejected from the lower mold (104), the rollers (313) on both sides approach the hand plate to limit the hand plate to prevent the hand plate from shifting, and then the hand plate can be taken out.
