Detailed Implementation

[0019] Example 1

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0021] As shown in the figure, this utility model provides a lifting injection molding part trimming device, including a worktable 1. The worktable 1 is characterized by a baffle 11 fixedly connected to one side, a bracket 12 fixedly connected to the middle of the worktable 1, a drive motor A121 fixedly connected to the outer top of the bracket 12, a screw 122 connected to the output end of the drive motor A121, a moving block 123 connected to the screw 122, a telescopic cylinder A124 fixedly connected to the moving block 123, a tool holder 125 fixedly connected to the telescopic end of the telescopic cylinder A124, and a cutting blade 125 connected to the tool holder 125. 6. A fan 127 is fixedly connected to one side of the bracket 12. A plug 13 is fixedly connected to one side of the bottom of the workbench 1. The plug 13 is detachably connected to the collection box 2. A drive motor B3 is fixedly connected to the other side of the bottom of the workbench 1. The output end of the drive motor B3 is connected to the support turntable 4. The support turntable 4 is fixedly connected to the mold placement plate 5. Adjustment rods 6 are connected to the four corners of the mold placement plate 5. A support plate 9 is fixedly connected to the surface of the workbench 1 next to the support turntable 4. A telescopic cylinder B7 is fixedly connected to the support plate 9. The telescopic end of the telescopic cylinder B7 is connected to the brush head 8.

[0022] A square groove 14 is provided on the surface of the workbench located in front of the brush head 8, and a collection box 2 is provided at the bottom of the square groove 14.

[0023] Slots 21 are provided on both sides of the top of the collection box 2, and a handle 22 is provided on the front side of the collection box 2.

[0024] A circular groove 51 is provided in the middle of the mold placement plate 5.
