[0002] The process from design to molding of plastic products is a very complicated one, which includes several key aspects such as plastic product design, mold structure design, mold processing and manufacturing, and plastic parts production. Injection molding is a processing method for mass production of certain parts with complex shapes. Injection molds are tools for producing plastic products and realizing injection molding. They are also tools that give plastic products complete structures and precise dimensions.

[0003] With the continuous development of the electric vehicle industry, plastic parts such as electric vehicle covers are generally injection molded. After injection molding, electric vehicle plastic parts need to be shaped using molds. During the shaping process, the mold needs to be heated, and then cooled and shaped before the mold is taken out to ensure the shape of the plastic part.

[0004] The existing demoulding method for EMU plastic parts is mostly manual demoulding, that is, manually prying the two ends of the core rod or the core to pry up the product. The manual demoulding method is not only difficult to pry up and has low work efficiency, but also easily causes the demoulding process to be unsmooth or even damage the plastic parts. Therefore, we need to upgrade and transform the existing technology. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, the present embodiment provides a straight-pushing demoulding mechanism for an oblique mounting hole of an electric vehicle plastic part, comprising a device body 1, the device body 1 comprising a workbench 6 and a lower mold 2, a mold groove 7 being opened in the lower mold 2, a plastic part 8 being arranged in the mold groove 7, a connecting buckle 9 being fixedly provided below the plastic part 8, a movable groove 10 being provided below the plastic part 8, a fixed block 11 being installed in the movable groove 10, a guide groove 12 being opened in the fixed block 11, a guide block 13 being installed in the guide groove 12, one side of the guide block 13 being connected to an oblique push plate 14, a slide groove 15 being provided in the front end of the oblique push plate 14, a T-shaped slider 16 being provided in the slide groove 15, one end of the T-shaped slider 16 being connected to an electric push rod 17, and a push rod 19 and an electric push rod 21 being provided on the left and right sides of the electric push rod 17 respectively.

[0024] Preferably, extension buckles 3 are fixedly connected to the outer walls at both ends of the left and right ends of the lower mold 2, and screw holes 4 are provided in the extension buckles 3 and the workbench 6. By providing the screw holes 4, the extension buckles 3 of the lower mold 2 can be aligned with the workbench 6, avoiding the trouble of installation. There are multiple groups of screw holes 4, and bolts 5 are installed in the multiple groups of screw holes 4. The bolts 5 are screwed with the screw holes 4, which can fix and limit the lower mold 2, making it convenient for users to disassemble and replace it later, increasing the practicality of the device and avoiding the trouble of inconvenient disassembly and assembly of the lower mold 2. The oblique push plate 14 is fixedly connected to the guide block 13, and the guide block 13 is slidably installed in the guide groove 12. The oblique push plate 14 is slidably connected to the fixed block 11, which increases the connectivity and intimacy between the devices and avoids the position displacement of the oblique push plate 14 of the device during movement.

[0025] Preferably, a connecting plate 18 is provided on the electric push rod 17, and a push rod 19 is provided at one end of the connecting plate 18. The push rod 19 is fixedly connected to the electric push rod 17 through the connecting plate 18, which increases the intimacy and connectivity between the devices, facilitates the user to control the device, and provides convenience for the user. A sleeve 20 is provided under the push rod 19, and the sleeve 20 is slidably connected to the push rod 19 and the sleeve 20 is fixedly installed in the workbench 6. By providing the sleeve 20, the moving direction of the push rod 19 can be guided to avoid the position displacement of the push rod 19 during the movement.

[0026] The use principle and use process of the utility model are as follows: when in use, by controlling the electric push rod 17 to work, the electric push rod 17 pushes the T-shaped slider 16 and the push rod 19 upward, and the T-shaped slider 16 moves in the slide groove 15 of the oblique push plate 14. During the movement, the T-shaped slider 16 pushes the oblique push plate 14 to move upward, and the oblique push plate 14 drives the guide block 13 to move in the guide groove 12 of the fixed block 11, and also drives the push rod 19 to move out of the sleeve 20.
