[0033] like Figure 2 , Figure 3 , Figure 6 As shown, the outer wall of the front inclined guide column 23 is movably sleeved with a stripping module 27, the outer wall of the stripping module 27 is slidably connected to the inner wall of the fixed mold base 1, the outer wall of the stripping module 27 is plugged into the inner wall of the movable mold base 21, the outer wall of the stripping module 27 overlaps the outer wall of the injection molded part 5, the left and right parts of the stripping module 27 are slidably connected with guide blocks 3 28, the outer wall of the guide blocks 3 28 is fixedly connected to the inner wall of the fixed mold base 1 by bolts, the bottom of the stripping module 27 is slidably connected with a guide block 4 29, the outer wall of the guide block 4 29 is fixedly connected to the inner wall of the fixed mold base 1 by bolts.

[0034] When the inclined guide column 23 slides, the stripping module 2 27 slides on the inner wall of the fixed mold base 1, and the guide block 3 28 and the guide block 4 29 guide and limit the stripping module 2 27, so that the stripping module 2 27 will not deviate and fall off when sliding, so that the stripping module 2 27 is away from the injection molded part 5, thereby completing the initial demolding and achieving the demolding effect.

[0035] like Figure 3 , Figure 5 As shown, the upper and lower parts of one end of the mounting plate 31 are fixedly connected with a switch 32, the button of the switch 32 is fixedly connected with an elastic contact 33, the outer wall of the elastic contact 33 at the bottom is overlapped with a lower stopper 34, the outer wall of the lower stopper 34 is fixedly connected to the inner wall of the ejector plate 11 by bolts, the outer wall of the elastic contact 33 at the top is overlapped with an upper stopper 35, the outer wall of the upper stopper 35 is fixedly connected with a cylinder 36, one end of the cylinder 36 is fixedly connected to one end of the fixed mold base 1 by bolts, the output end of the cylinder 36 is fixedly connected with a connecting block 37, the outer wall of the connecting block 37 is clamped with the inner wall of the ejector plate 11.

[0036] At the same time, the cylinder 36 is started, and the cylinder 36 drives the connecting block 37 to move upward, and the connecting block 37 drives the ejector plate 11 to move synchronously, so that the ejector plate 11 drives the fixing sleeve 14 to slide on the outer wall of the return pin 13, and at the same time, the ejector plate 11 drives the ejector pin 15 and the ejector pin 2 16 to move synchronously, and the return pin 13 guides the ejector plate 11, so that the ejector plate 11 moves more smoothly, and at the same time, the ejector plate 11 drives the upper stopper 35 to move synchronously, so that the outer wall of the upper stopper 35 contacts the outer wall of the elastic contact 33. When the outer wall of the upper stopper 35 is not on the outer wall of the elastic contact 33, the cylinder 36 is closed at this time, thereby allowing the cylinder 36 to close automatically.

[0037] like Figure 2 , Figure 6 , Figure 7 As shown, the top of the inclined ejector pin 41 is movably sleeved with a guide sleeve 42, the bottom end of the guide sleeve 42 is fixedly connected with a fixed block 43, the top of the fixed block 43 is fixedly connected to the inner wall of the fixed mold base 1 by bolts, the top of the inclined ejector pin 41 is fixedly connected with a ejector block, the outer wall of the ejector block overlaps the inner wall of the injection molded part 5, the bottom end of the inclined ejector pin 41 is rotatably connected with a slider 45, the outer wall of the slider 45 is slidably connected with a fixed frame 44, and the top of the fixed frame 44 is fixedly connected to the bottom of the ejector plate 11 by bolts.

[0038] When the ejector plate 11 moves upward, the fixed frame 44 drives the inclined ejector 41 to move synchronously. Because the inclined ejector 41 has a certain angle and the guide sleeve 42 is fixed and cannot move, when the inclined ejector 41 slides on the inner wall of the guide sleeve 42, the slider 45 connected to the bottom end of the inclined ejector 41 slides on the inner wall of the fixed frame 44, thereby causing the inclined ejector 41 to slide upward on the inner wall of the guide sleeve 42, driving the ejector block to move synchronously, so that the ejector block ejects the injection molded part 5, thereby completing the demoulding of the injection molded part 5, achieving the demoulding effect.

[0039] The working principle of the utility model is as follows: when it is necessary to demould, the fixed mold seat 1 and the movable mold seat 21 are opened, so that the movable mold seat 21 drives the fixing bolt 22 to move upward synchronously, and at the same time, the fixing bolt 22 drives the inclined guide column 23 to move synchronously, so that the inner wall of the inclined guide column 23 slides on the outer wall of the limit block 231, and the limit block 231 limits and guides the inclined guide column 23, so that the inclined guide column 23 slides more smoothly, and at the same time, the inclined guide column 23 slides on the inner walls of the stripping module 1 24 and the stripping module 2 27. When the inclined guide column 23 slides upward, the stripping module 1 24 slides on the inner wall of the fixed mold seat 1, and the stripping module 1 24 is guided by the guide block 1 25 and the guide block 26. The stripping module 1 24 is guided and limited so that it will not deviate and fall off when sliding. At the same time, the stripping module 2 27 slides on the inner wall of the fixed mold base 1. The guide block 3 28 and the guide block 4 29 guide and limit the stripping module 2 27 so that it will not deviate and fall off when sliding. In this way, the stripping module 1 24 and the stripping module 2 27 are kept away from the injection molded part 5, thereby completing the preliminary demoulding and achieving the demoulding effect. At the same time, the cylinder 36 is started, and the cylinder 36 drives the connecting block 37 to move upward. The connecting block 37 drives the ejector plate 11 to move synchronously, so that the ejector plate 11 drives the fixed sleeve 14 to slide on the outer wall of the return pin 13. At the same time, the ejector plate 11 drives the ejector 1 15 and the ejector 2 16 The return pin 13 guides the ejector plate 11 to make the ejector plate 11 move more smoothly. At the same time, the ejector plate 11 drives the fixed frame 44 to move upward synchronously, so that the fixed frame 44 drives the inclined ejector 41 to move synchronously. Because the inclined ejector 41 has a certain angle and the position of the guide sleeve 42 is fixed and cannot move, when the inclined ejector 41 slides on the inner wall of the guide sleeve 42, the slider 45 connected to the bottom end of the inclined ejector 41 rotates and slides on the inner wall of the fixed frame 44, so that the inclined ejector 41 slides upward on the inner wall of the guide sleeve 42, driving the ejector block to move synchronously, so that the ejector block ejects the injection molded part 5, thereby completing the demoulding of the injection molded part 5, achieving the demoulding effect. When demoulding workpieces at different angles, the angle of the beveled ejector pin 41 is changed, and the beveled ejector pin 41 is rotated to make the beveled ejector pin 41 rotate on the outer wall of the slider 45, so as to change the angle of the beveled ejector pin 41, so that the beveled ejector pin 41 can demould workpieces at different angles, thereby increasing the practicality of the beveled ejector pin 41 and achieving the effect of increasing practicality. Moreover, when the ejector plate 11 moves upward, the upper stopper 35 is driven to move synchronously, so that the outer wall of the upper stopper 35 contacts the outer wall of the elastic contact 33. When the outer wall of the upper stopper 35 is not on the outer wall of the elastic contact 33, the cylinder 36 is closed at this time, so that the cylinder 36 can close itself, thereby greatly improving the user experience.
