DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-5As shown, the present invention provides a post-processing device for electric drill plastic shell molding, comprising a workbench 1, a mold base 3 is installed at the top end of the workbench 1, and a molding assembly for pressing the electric drill plastic shell is arranged on the upper surface of the mold base 3, and four fixed columns 7 are arranged on one side of the mold base 3, and the top ends of the four fixed columns 7 are commonly connected to a fixed top plate 8, and a sliding side plate 9 for limiting the molded electric drill plastic shell is slidably installed on the bottom surface of the fixed top plate 8, and an extension plate 12 extending into the molding assembly is slidably installed on the bottom surface of the fixed top plate 8, and a rotating adsorption assembly for adsorbing two molded electric drill plastic shells is installed on the lower surface of the extension plate 12, and a rotating frame 25 is rotatably installed on the middle part of the side of the sliding side plate 9, and a limiting pin 26 for limiting the hole groove of the electric drill plastic shell is installed on the inner wall surface of the rotating frame 25. The rotating adsorption assembly is used to rotate the two electric drill plastic shells in opposite directions and abut the electric drill plastic shells in the corresponding rotating frame 25. There is an electric push rod 24, and a grinding component for deburring the edge of the rotating electric drill plastic shell is installed at the pushing end of the electric push rod 24. The electric drill plastic shell is first molded by the molding component, and then the molding component is opened to release pressure. The extension plate 12 at the bottom of the fixed top plate 8 extends into the opened molding component, and a group of electric drill plastic shells are first adsorbed and fixed by the rotating adsorption component. After that, after the extension plate 12 is reset to the lower surface of the fixed top plate 8, the rotating adsorption component rotates a group of electric drill plastic shells 90 degrees in different directions at the same time. At this time, the electric drill plastic shell changes from a horizontal state to a vertical state, and then the two sliding side plates 9 synchronously slide toward the middle of the fixed top plate 8, and the electric drill plastic shell enters the rotating frame 25, and the prefabricated hole groove of the electric drill plastic shell is plugged by the limit pin 26. At this time, the electric drill plastic shell is limitedly installed in the rotating frame 25, and the electric drill plastic shell is driven to rotate together through the rotation of the rotating frame 25, and the edge of the electric drill plastic shell is polished in the vertical direction by the grinding component.

[0031] See also Figure 2 and Figure 3As shown, the rotating adsorption assembly includes an electric push rod 13 installed in the middle of the bottom surface of the extension plate 12, the pushing end of the electric push rod 13 is fixedly connected to the lifting plate 18, and the middle of the bottom surface of the lifting plate 18 is fixedly installed with a mounting frame 20, and a steering rod 1 22 and a steering rod 2 23 with opposite rotation directions are rotatably installed in the mounting frame 20, and the ends of the steering rod 1 22 and the steering rod 2 23 are both installed with bevel gears 21 meshed with intermediate helical gears, and the steering rod 1 22 and the steering rod 2 23 are coaxially arranged, and the ends of the steering rod 1 22 and the steering rod 2 23 are both rotatably installed with suction cups 19, and the rotation direction of the suction cups 19 is inconsistent with the rotation direction of the steering rods 1 22 and the steering rods 23, and the suction cups 19 and the rotating frame 25 are opposite in rotation direction. At the same time, it is convenient to realize the rotation of the limited electric drill plastic shell. When the extension plate 12 reaches the opened molded component, the electric push rod 13 pushes the lifting plate 18 downward, driving the suction cups 19 on the steering rod 1 22 and the steering rod 23 to move downward synchronously, and use the suction cups 19 to absorb and take out a group of electric drill plastic shells. After taking out, the extension plate 12 is reset to leave the opened molded component, and the two bevel gears 21 are driven by the middle bevel gear to rotate in opposite directions at the same time until the steering rod 1 22 and the steering rod 23 are rotated 90 degrees in different directions and then stop rotating. At this time, the electric drill plastic shell absorbed by the suction cup 19 changes from a horizontal state to a vertical state, which is convenient for the subsequent vertical installation of the electric drill plastic shell and the grinding of the edge.

[0032] See also Figure 2 As shown, on the bottom surface of the extension plate 12, T-shaped guide rods 15 are installed on both sides of the electric push rod 13. The outside of the guide rod 15 is sequentially sleeved with a spring 16 and a spring 2 17 from top to bottom. The ends of the spring 16 and the spring 2 17 are respectively fixed to the upper surface and the lower surface of the lifting plate 18. In the initial state, as shown in FIG. Figure 2 As shown, when the electric push rod 13 pushes the lifting plate 18 downward, the spring 16 is stretched, and the spring 2 17 is squeezed to produce elastic compression, and the lifting plate 18 slides on the upper limit of the guide rod 15. When the electric push rod 13 is powered off, the lifting plate 18 rises to the initial height under the elastic tension of the spring 16 and the spring 2 17.

[0033] See also Figure 2 As shown, a guide groove 10 is provided at one end of the bottom surface of the fixed top plate 8, and a guide block 11 fixedly connected to the upper surface of the extension plate 12 is slidably installed inside the guide groove 10. A stroke cylinder 14 for pushing the extension plate 12 to slide horizontally is installed at the other end of the bottom surface of the fixed top plate 8. After the molded component is formed into the plastic shell of the electric drill, the molded component is opened, and the stroke cylinder 14 pushes the extension plate 12 to slide horizontally along the bottom surface of the fixed top plate 8. During the sliding process, the guide block 11 is guided by the limit position in the guide groove 10 to provide guide support for the sliding of the extension plate 12.

[0034] See also Figure 4 As shown, two linear guides are symmetrically arranged on the bottom surface of the fixed top plate 8, and a sliding seat connected to the sliding side plate 9 is slidably installed on the outside of each linear guide, and the bottom inner wall surface of the sliding side plate 9 is an inclined surface, and a dust box 29 is adapted to be installed between the two adjacent sliding side plates 9. A vacant groove 2 is provided on the top surface of the workbench 1, which is engaged with the dust box 29. The top of the dust box 29 is inclined outward and is arranged to fit the inner wall surface of the sliding side plate 9. First, the dust box 29 is inserted into the vacant groove 2. When the extension plate 12 transports the adsorbed electric drill plastic shell to the top of the vacant groove 2, the steering rod 1 22 and the steering rod 23 are rotated to make a group of electric drill plastic shells rotate in opposite directions respectively, and then the two sliding side plates 9 approach toward the middle until the top of the dust box 29 fits the inner wall surface of the sliding side plate 9. Through the arrangement of the two sliding side plates 9 and the dust box 29, the waste chips generated by grinding are naturally reduced.

[0035] See also Figure 4 and Figure 5 As shown, the grinding assembly includes a fixed block 30 connected to the pushing end of the electric push rod 24, and two vertical plates 31 are installed on the bottom surface of the fixed block 30. The inner wall surfaces of the two vertical plates 31 are fixedly connected with hollow sleeves 37. The end of the hollow sleeve 37 is rotatably installed with a grinding roller 33 that contacts the outer edge of the electric drill plastic shell. The shaft at the end of the grinding roller 33 passes through the interior of the hollow sleeve 37, and the outer surface of each hollow sleeve 37 is clamped with a grinding disk 34 that contacts the side of the edge of the electric drill plastic shell. During grinding, the rotation of the rotating frame 25 drives the limited electric drill plastic shell to rotate together, and the outer edge of the electric drill plastic shell is grinded by the self-rotating grinding roller 33, and the two side surfaces of the edge of the electric drill plastic shell are grinded by the friction between the rotating electric drill plastic shell and the grinding disks 34 on both sides. The grinding efficiency is high, and the waste chips polished on the outer edge and the two side surfaces of the edge settle into the inner cavity of the dust collecting box 29 under gravity.

[0036] See also Figure 5 As shown, a plurality of groups of annularly arranged telescopic rods 36 are installed between the vertical plate 31 and the grinding disc 34, and a synchronous cylinder 32 is installed on the outer wall surface of the vertical plate 31 for pushing the grinding disc 34 to slide along the key block limit on the hollow sleeve 37. The synchronous cylinder 32 drives the two grinding discs 34 to slide synchronously on the upper limit of the hollow sleeve 37. At this time, the distance between the grinding disc 34 and the grinding roller 33 changes, which can adapt to the deburring processing of the edge of the plastic shell of the electric drill with different thicknesses.

[0037] See also Figure 1As shown, the molding assembly includes a lower mold 4, a movable mold 6 is arranged just above the lower mold 4, and two mold cavities 5 are arranged on the top surface of the lower mold 4. A punch used in conjunction with the mold cavity 5 is installed on the bottom surface of the movable mold 6. By pressing the movable mold 6 downward, the punch enters the mold cavity 5 to mold the injection liquid, thereby obtaining the electric drill plastic shell.

[0038] The present invention also provides a processing method for a post-molding processing device of an electric drill plastic shell, the molding method comprising the following steps:

[0039] Step 1: Use a molding component to shape a group of electric drill plastic shells, then use a rotating adsorption component to adsorb and fix them, and then rotate a group of electric drill plastic shells 90 degrees in different directions at the same time, so that the electric drill plastic shells change from a horizontal state to a vertical state;

[0040] Step 2: After that, the two sliding side plates 9 are moved closer to each other under the sliding of the linear guide rail, and the limit pins 26 in the rotating frame 25 enter the prefabricated hole groove of the electric drill plastic shell, and the sucker 19 is rotated and pressed, and then the rotating frame 25 drives the pressed electric drill plastic shell to rotate, and the outer edge of the electric drill plastic shell is vertically polished;

[0041] Step 3: The outer surface of the electric drill plastic shell is directly polished by the polishing roller 33, and the edge side of the electric drill plastic shell is polished by two polishing discs 34. The distance between the polishing disc 34 and the polishing roller 33 is controlled by the synchronous cylinder 32 to change the polishing thickness of the outer edge of the electric drill plastic shell.

[0042] When the present invention is in use, the extension plate 12 at the bottom of the fixed top plate 8 extends into the opened molded component, and a group of electric drill plastic shells are first adsorbed and fixed by means of the rotating adsorption component. After that, after the extension plate 12 is reset to the lower surface of the fixed top plate 8, the rotating adsorption component simultaneously rotates a group of electric drill plastic shells 90 degrees in opposite directions. At this time, the electric drill plastic shell changes from a horizontal state to a vertical state, and then the two sliding side plates 9 synchronously slide toward the middle of the fixed top plate 8, and the electric drill plastic shell enters the rotating frame 25, and the prefabricated hole groove of the electric drill plastic shell is plugged by the limit pin 26. At this time, the electric drill plastic shell is in a vertical state and is limitedly installed in the rotating frame 25. The electric drill plastic shell is driven to rotate together through the rotation of the rotating frame 25, so that the edge of the electric drill plastic shell can be polished in the vertical direction by the polishing component.

[0043] The rotation of the rotating frame 25 drives the electric drill plastic shell to rotate together after being limited, and the outer edge of the electric drill plastic shell is polished by the self-rotating grinding roller 33, and the two side surfaces of the edge of the electric drill plastic shell are polished by the friction between the rotating electric drill plastic shell and the grinding discs 34 on both sides, with high grinding efficiency. The waste chips polished on the outer edge and the two side surfaces of the edge settle into the inner cavity of the dust collecting box 29 under gravity;

[0044] The two grinding discs 34 are driven by the synchronous cylinder 32 to slide synchronously on the upper limit of the hollow sleeve 37. At this time, the distance between the grinding disc 34 and the grinding roller 33 changes, which is suitable for deburring the edge of the electric drill plastic shell with different thicknesses.
