DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] An injection mold for an automotive sensor plug assembly, such as Figure 1 and Figure 2 , comprising a horizontally distributed workbench 1, two lower molds 2 arranged on the workbench 1, and an upper mold 3 that cooperates with the two lower molds 2; It also includes a power assembly for allowing the upper mold 3 to move up and down, and a position-changing assembly for allowing the two lower molds 2 to be alternately positioned below the upper mold 3; The transposition assembly enables the two lower molds 2 to rotate and move, and the two lower molds 2 are located in a straight line; It also includes a storage box 11 and a storage box 2 12 placed on the workbench 1 and located on the side of the lower mold 2 away from the upper mold 3. The storage box 11 is used to store the copper bushing 4, and the storage box 2 12 is used to store the pin 5. The copper bushing 4 and the pin 5 are placed on the lower mold 2 that is rotated away from the upper mold 3.

[0022] like Figure 1 and Figure 2 , the power component makes the upper mold 3 and the lower mold 2 located below the upper mold 3 close together, and then the plastic shell 6 of the automobile sensor plug assembly is injected. After the injection molding is completed, the transposition component rotates the other lower mold 2 with the copper bushing 4 and the pin 5 installed to the bottom of the upper mold 3, so that the power component drives the upper mold 3 to close the mold with the lower mold 2 for injection molding. At this time, the lower mold 2 that has been injected is rotated to a position away from the upper mold 3 to facilitate the removal of the injection molded part. Subsequently, the copper bushing 4 and the pin 5 are placed in the lower mold 2, waiting to be moved to the bottom of the upper mold 3 for injection molding. The above steps are repeated. At this time, two lower molds 2 are used so that the copper bushing 4 and the pin 5 can be placed in the lower mold 2 in advance, reducing the time when the mold stops working and improving production efficiency.

[0023] like Figure 1 and Figure 4The transposition component includes a circular turntable 13 rotatably arranged on the upper end surface of the workbench 1, two lower molds 2 are fixed on the upper end disk surface of the turntable 13, and the two lower molds 2 are located at both ends of the diameter direction of the turntable 13, and a through hole 131 is coaxially opened at the center of the turntable 13, and a gear ring 132 is provided on the lower end surface of the turntable 13, which is coaxially distributed with the through hole 131 and has an inner diameter larger than the aperture of the through hole 131. The lower end surface of the workbench 1 supports the workbench 1 from the ground through a number of vertical plates 14, and a servo motor 133 is provided on the vertical plate 14. At this time, a plate can be horizontally extended from the vertical plate 14 for installing the servo motor 133, and a driving gear 134 meshing with the gear ring 132 is coaxially provided on the rotating shaft of the servo motor 133, and the teeth of the gear ring 132 are located on the outer wall of the gear ring 132.

[0024] like Figure 1 and Figure 4 The working principle of the transposition component is as follows: the servo motor 133 drives the gear ring 132 to rotate through the driving gear 134. The gear ring 132 is installed on the turntable 13, thereby driving the turntable 13 to rotate back and forth 180°, that is, rotating 180° clockwise to rotate one lower mold 2 to the bottom of the upper mold 3, and then rotating 180° counterclockwise to rotate the other lower mold 2 to the bottom of the upper mold 3, so as to achieve the purpose of the two lower molds 2 appearing alternately under the upper mold 3.

[0025] like Figure 1 and Figure 4 The power assembly includes a vertical column 135 passing through the through hole 131. The upper end of the vertical column 135 is provided with a column 136. The upper end of the column 136 is provided with a fixed plate 137 for mounting the upper mold 3. The lower end of the vertical column 135 is driven up and down by an electric cylinder 138. At this time, the electric cylinder 138 drives the vertical column 135 to move up and down, thereby driving the column 136 to move up and down. At this time, the vertical column 135 and the column 136 are coaxially distributed with the electric cylinder 138, which facilitates the upward and downward movement of the fixed plate 137, so that the fixed plate 137 drives the upper mold 3 to move up and down, realizing the opening and closing of the upper mold 3 and the lower mold 2. The upper end of the fixed plate 137 is provided with a barrel of an injection molding machine for injecting molten material into the upper mold 3 and a storage barrel connected to the barrel. The barrel is vertically distributed, and the storage barrel opens upward. This is a prior art and will not be described in detail here.

[0026] like Figure 3 and Figure 6 and Figure 7 and Figure 9The lower mold 2 includes a lower template 21 fixed to the upper end surface of the turntable 13, two support plates 22 arranged at both ends of the upper end surface of the lower template 21, a lower cavity mounting plate 23 arranged at the upper ends of the two support plates 22, a lower cavity plate 24 installed in the upper end surface of the lower cavity mounting plate 23, a back plate 25 located between the two support plates 22, and an ejector mounting plate 26 fixed to the side of the back plate 25 facing the lower cavity mounting plate 23, and a plurality of ejectors 261 arranged on the side of the ejector mounting plate 26 facing away from the back plate 25, the upper end of each ejector 261 extends to the upper end surface of the lower cavity plate 24, and the upper end surface of the lower cavity plate 24 is flush with the upper end surface of the lower cavity mounting plate 23; like Figure 3 and Figure 6 and Figure 7 and Figure 9 , the upper end surface of the lower cavity plate 24 is provided with a main branch channel 27, the lower end surface of the turntable 13 is provided with an electric cylinder 2 located below each lower template 21, and each lower template 21 is penetrated by a driving column passing through the lower end surface of the turntable 13. The piston rod of the electric cylinder 2 contacts the lower end of the driving column and drives the driving column to move upward. The driving column passes through the lower template 21 and is fixedly connected to the lower end surface of the back plate 25. The upper end surface of the ejector mounting plate 26 is provided with a mounting column extending to the bottom of the lower cavity mounting plate 23. The outer wall of the mounting column is provided with a compression spring 28. The upper and lower ends of the compression spring 28 respectively contact with On the lower cavity mounting plate 23 and the ejector mounting plate 26; when it is necessary to push the ejector mounting plate 26 and the back plate 25 upward, the piston rod of the electric cylinder 2 drives the driving column to move upward (not shown in the figure). At this time, the compression spring 1 28 is in a compressed state. When the ejector mounting plate 26 needs to be reset, the piston rod of the electric cylinder 2 moves downward, and the compression spring 1 28 drives the ejector mounting plate 26 downward, thereby resetting the ejector 261. The reason why the piston rod of the electric cylinder 2 is in contact with the driving column instead of being fixedly connected is to facilitate the disassembly and assembly of the lower mold 2 in the later stage.

[0027] like Figure 5 and Figure 8 The upper mold 3 includes an upper template 31 and an upper cavity mounting plate 32 fixed to the lower end surface of the upper template 31. An upper cavity plate 33 is provided on the lower end surface of the upper cavity mounting plate 32. The upper cavity plate 33 corresponds to and cooperates with the lower cavity plate 24 to form the outer wall of the plastic shell 6 of the automobile sensor plug assembly. A pouring gate 34 and a main flow channel connected to the pouring gate are opened on the upper template 31. The main flow channel extends to the upper cavity plate 33 and is connected to the main branch channel 27 of the lower cavity plate 24.

[0028] like Figure 3 and Figure 6 and Figure 7The main flow channel is connected to the middle position of the main branch flow channel 27. The two ends of the main branch flow channel 27 are respectively used to form a plastic shell 6 of an automobile sensor plug assembly. The upper end surface of the lower cavity plate 24 is provided with a secondary branch flow channel 29 connected to the main branch flow channel 27 at both ends of the main branch flow channel 27. Both ends of the secondary branch flow channel 29 extend to both sides of the main branch flow channel 27, that is, the secondary branch flow channel 29 is vertically distributed with the main branch flow channel 27, and one end of each secondary branch flow channel 29 is connected to a lifting plate 231 for sliding up and down. At this time, the lifting plate 231 slides up and down. Move to the lower cavity mounting plate 23, each secondary flow channel 29 is provided with a placement block 241 on the bottom wall near the lifting plate 231, the upper end of the placement block 241 is U-shaped, and the placement block 241 is provided with a rod 242 on both upper end surfaces of the U-shape, and the rod 242 is for the opening on the pin 5 to pass through. At this time, there are two pins 5 in the plastic shell 6 of an automobile sensor plug assembly, so two rods 242 are provided, and each lifting plate 231 is provided with a protective block 232 located outside the placement block 241, and the protective block 232 is opened. There is a matching port 233 for placing the placement block 241, and the matching port 233 passes through the placement block 241 from top to bottom. The protective block 232 is embedded in the lower cavity plate 24. At this time, the width of the protective block 232 and the lifting plate 231 are wider than the width of the secondary branch channel 29. After the protective block 232 is embedded in the lower cavity plate 24, the placement block 241 is inserted into the matching port 233. The upper ends of the lifting plate 231, the protective block 232, the placement block 241 and the insertion rod 242 all extend out of the lower cavity plate 24. Therefore, the upper cavity plate 33 is provided with The matching molding groove, when injection molding, the molten material in the secondary branch channel 29 flows to the placement block 241 and enters the two vertical sides of the U-shaped placement block 241. The distance between the two pins 5 is smaller than the width of the secondary branch channel 29. The purpose is to facilitate the pins 5 to be located in the molten material when the secondary branch channel 29 is filled with molten material. The pins 5 at the upper end of the placement block 241 do not come into contact with the molten material because the upper mold 3 has correspondingly distributed parts pressing on the upper end of the placement block 241, thereby forming the following Figure 13 Automobile sensor plug assembly; like Figure 3 and Figure 6 and Figure 7The lower cavity plate 24 is connected to a lifting rod 234 that slides up and down near the main flow channel. The lifting rod 234 is located on one side of the lifting plate 231 and is closer to the secondary flow channel 29 than the lifting plate 231. The end face of the lifting rod 234 is provided with an embedded column 235 that contacts the lower cavity plate 24. The lower end portion of the embedded column 235 is embedded in the lower cavity plate 24, and the end face of the embedded column 235 is flush with the side wall of the main flow channel 27. A positioning rod 236 extending toward the main flow channel 27 is provided on the end face of the embedded column 235. The diameter of the positioning column is smaller than the diameter of the embedded column 235. The positioning rod 236 Used to sleeve the copper bushing 4, a limiting column 237 coaxially distributed with the positioning rod 236 is fixedly embedded on the upper end face of the lower cavity plate 24, and the diameter of the limiting column 237 is the same as the diameter of the embedded column 235. The end face of the limiting column 237 is flush with the side wall of the main branch channel 27, and the limiting column 237 and the embedded column 235 are relatively distributed. One end of the positioning rod 236 is in conflict with the end face of the limiting column 237; the upper ends of the lifting rod 234, the embedded column 235, the positioning rod 236, and the limiting column 237 all extend out of the upper end face of the lower cavity plate 24, so the upper cavity plate 33 is provided with a forming groove that matches them.

[0029] like Figure 3 and Figure 6 and Figure 7 and Figure 9 The lower ends of the lifting rod 234 and the lifting plate 231 extend out of the lower end surface of the lower cavity plate 24 and are fixedly connected to two of the ejector pins 261. The end surfaces of the remaining ejector pins 261 are located at the bottom of the secondary runner 29 and are flush with the bottom of the secondary runner 29, so as to facilitate ejection of the molded injection molded parts. like Figure 3 and Figure 6 and Figure 7 , a slide groove 243 is provided on the lower cavity plate 24, and the slide groove 243 extends out of the side wall of the lower cavity mounting plate 23 at one end away from the lower cavity plate 24, and a connecting groove 244 is provided on the lower cavity plate 24 so that the slide groove 243 is connected with the end of the two secondary flow channels 29 away from the lifting plate 231, and the lower cavity plate 24 is horizontally slidably connected to the slide plate 245 through the slide groove 243, and a slider 246 that cooperates with the connecting groove 244 is placed in the connecting groove 244, and the width of the slider 246 is greater than the width of the secondary flow channel 29, and the slider 246 is provided with a The placement cylinder 2461 in the flow channel 29 has a gap between the lower end of the placement cylinder 2461 and the bottom of the secondary branch flow channel 29, and the upper end extends out of the upper end of the lower cavity plate 24. A slot for inserting the pin 5 is provided in the placement cylinder 2461. The slot is distributed on the inner bottom wall of the placement cylinder 2461 and is opposite to the insertion rod 242 on the placement block 241. The size of the insertion rod 242 on the placement block 241 is smaller than the size of the hole on the pin 5. When the upper mold 3 and the lower mold 2 are closed, the upper mold 3 is provided with a pushing member that causes the slide plate 245 to press the slider 246.

[0030] like Figure 5 and Figure 6 and Figure 8 , guide columns 35 are provided at the four corner points of the lower end surface of the upper cavity mounting plate 32, and a guide groove 36 for inserting the guide columns 35 is provided on the lower cavity mounting plate 23. The pushing member includes a pushing rod 37 provided on the lower end surface of the upper cavity plate 33. The pushing rod 37 is an inclined rod and is gradually inclined downward from the lower end surface of the upper cavity mounting plate 32 to the edge of the upper cavity mounting plate 32. An inclined groove 371 for inserting the pushing rod 37 is provided on the slide plate 245 and the lower cavity mounting plate 23; like Figure 5 and Figure 6 and Figure 8 When the mold is opened, a pulling member is provided on the slide plate 245 to move the slider 246 away from the secondary branch channel 29.

[0031] like Figure 3 and Figure 7 The pulling member includes an open slot 2462 formed on the side of the slider 246 facing the slide plate 245, and a stopper 2463 extending toward each other is provided on the opposite notch of the open slot 2462. The slide plate 245 is provided with a driving slot distributed toward the open slot 2462, and two swing plates 2464 are rotatably connected in the driving slot. One end of the two swing plates 2464 extends out of the driving slot and enters the open slot 2462, and a baffle 2465 is provided at the end of the entry to abut against the stopper 2463. When the two swing plates 2464 enter the open slot 2462 and cause the stopper 2463 to abut against the baffle 2465, a gap exists between the baffle 2465 and the bottom of the open slot 2462. like Figure 3 and Figure 7The baffle 2465 and the stopper 2463 are both provided with an arc surface 2466 on the side away from the mutual conflict, and the two swing plates 2464 are connected by a compression spring 2467. When the two swing plates 2464 have not entered the opening groove 2462 and the compression spring 2467 is in a natural state, the arcuate surfaces 2466 on the two baffles 2465 are respectively distributed relative to the arcuate surfaces 2466 on the two stoppers 2463, and at this time, the two vertical opposite groove walls of the driving groove respectively contact the opposite sides of the two swing plates 2464, restricting the two swing plates 2464 from moving away from each other. As the slide plate 245 moves toward the slider 246, the two arcuate surfaces 2466 contact each other, and the arcuate surface 2466 on the stopper 2463 causes the thickness of the stopper 2463 to gradually decrease from the notch direction of the opening groove 2462, and the arcuate surface 2466 on the baffle 2465 causes the thickness of the baffle 2465 to gradually decrease from the direction away from the swing plate 2464. After the curved surface 2466 on the baffle 2465 comes into contact with the curved surface 2466 on the stop block 2463, the curved surface 2466 on the baffle 2465 will squeeze the curved surface 2466 on the baffle 2465, causing the baffle 2465 to move into the opening groove 2462 while causing the two rocking plates 2464 to swing toward each other, thereby compressing the compression spring 2467 to have an elastic restoring force. When one end of the rocking plate 2464 and the baffle 2465 enter the opening groove 2462, the baffle 2465 and the stop block 2463 are separated, and the compression spring 2467 drives the two rocking plates 2464 to swing away from each other under the action of the elastic restoring force until the baffle 2465 is distributed relative to the stop block 2463 and one side of the slide plate 245 comes into contact with the slider 246, thereby causing the slider 246 to come into contact with the groove wall of the connecting groove 244 and close one end of the secondary branch channel 29.

[0032] The upper ends of the slide plate 245 , the slider 246 , and the placement cylinder 2461 all extend out of the upper end surface of the lower cavity plate 24 , so the upper cavity plate 33 is provided with grooves that match them.

[0033] like Figure 1-9 The working principle of closing and opening the lower mold 2 and the upper mold 3: Step 1: After the lower mold 2 equipped with the copper bushing 4 and the pin 5 rotates to the position directly below the upper mold 3, the upper mold 3 moves downward under the drive of the power assembly. At this time, each guide column 35 is inserted into the guide groove 36, and the lower end of the push rod 37 is inserted into the inclined groove 371. As the lower mold 2 descends, the push rod 37 drives the slide plate 245 to move toward the slider 246, so that the two swing plates 2464 enter the open groove 2462. The slide plate 245 contacts one side of the slider 246, squeezing the slider 246 to the bottom of the connecting groove 244. At this time, the upper mold 3 and the lower mold 2 are closed. Step 2: After the injection molding is completed, the power assembly drives the upper mold 3 to move upward. At this time, the push rod 37 gradually moves out of the inclined groove 371, thereby driving the slide plate 245 to move away from the slider 246. At this time, the baffle 2465 on the swing plate 2464 contacts the block 2463, thereby causing the slider 246 to move away from the secondary runner 29 along with the slide plate 245. At this time, the slider 246 drives the placement cylinder 2461 to move together, so that the placement cylinder 2461 is separated from the molded part. Step 3: The turntable 13 rotates 180°, so that the lower mold 2 that has been injected is rotated away from the upper mold 3. The lower mold 2 waiting to be injected is transferred to the bottom of the upper mold 3 for injection molding. The electric cylinder 2 corresponding to the lower mold 2 that has been injected starts to work. The piston rod of the electric cylinder 2 drives the driving column to move upward, pushing the ejector mounting plate 26 and the back plate 25 to move upward, thereby causing the ejector 261 on the ejector mounting plate 26 to eject the molded part. In addition, another ejector 261 drives the ejection rod 234 and the lifting plate 231 to move upward, so that the molded part is taken out of the lower cavity plate 24 and placed on the positioning rod 236 and the protective block 232. Only the molded part needs to be taken out. Step 4: After taking out the injection molded part, place the copper bushing 4 on the two ejected positioning rods 236. Then, the piston rod of the second electric cylinder moves downward, and the compression spring 1 28 drives the ejector mounting plate 26 to move downward, thereby causing the ejector 261, the lifting plate 231, and the lifting rod 234 to reset, until the embedded column 235 on the lifting rod 234 contacts the lower cavity plate 24 and the protective block 232 on the lifting plate 231 contacts the lower cavity plate 24. Step 5: After inserting the pin 5 into the placement cylinder 2461, place the slider 246 into the connecting groove 244. At this time, the placement cylinder 2461 is located in the secondary branch channel 29, and the pin 5 in the placement cylinder 2461 is inserted into the insertion rod 242 on the placement block 241. After the lower mold 2 that is molded with the upper mold 3 is also injection-molded, rotate the turntable 13 so that the lower mold 2 with the pin 5 and the copper bushing 4 installed is rotated to the bottom of the lower mold 2 for injection molding; the cycle is repeated to reduce the injection molding downtime, improve production efficiency, and increase the output of injection molded products.

[0034] like Figure 10 and Figure 11 and Figure 12 In order to automatically load the copper bushing 4 and remove the injection molded part, a picking component is also included. The picking component removes the injection molded part on the lower mold 2 that is rotated away from the upper mold 3 and puts the copper bushing 4 into it.

[0035] like Figure 10 and Figure 11 and Figure 12The picking assembly includes a picking box 141 that is arranged on the vertical plate 14 and distributed vertically. The box mouth of the picking box 141 is distributed upward and extends out of the upper end surface of the workbench 1. One side box wall of the picking box 141 extends out of the vertical plate 14. The inner box bottom of the picking box 141 is rotatably connected to a passive gear 142. The inner box bottom of the picking box 141 is rotatably provided with a driven gear 143 that meshes with the passive gear 142. The outer box bottom of the picking box 141 is provided with a servo motor 2 144 that drives the driven gear 143 to rotate; the servo motor 2 144 drives the driven gear 143 to rotate, thereby driving the passive gear 142 to rotate.

[0036] like Figure 10 and Figure 11 and Figure 12 , an electric cylinder 3 145 is fixedly provided on the upper end surface of the passive gear 142, the axis of the electric cylinder 3 145 is coaxially distributed with the axis of the passive gear 142, the piston rod of the electric cylinder 3 145 is vertically distributed upward and extends out of the upper end of the workbench 1, a telescopic plate 146 is provided on the piston rod of the electric cylinder 3 145, one end of the telescopic plate 146 is provided with a picking plate 1461 distributed perpendicular to the length direction of the telescopic plate 146, the lower end of the picking plate 1461 is provided with an adjusting groove 1462 distributed along the length direction of the picking plate 1461, and two adjusting blocks 1463 are slidably connected in the adjusting groove 1462, and the lower ends of the two adjusting blocks 1463 extend out of the adjusting groove 146 2 and an air claw 1464 is fixedly connected to the extended end, and a screw 1465 is rotatably connected to the opposite groove wall of the adjusting groove 1462. The thread on the screw 1465 has two sections and the threads are opposite. The screw 1465 passes through each adjusting block 1463 and the two sections of thread on the screw 1465 are respectively threadedly connected to the two adjusting blocks 1463. A servo motor three 1466 for driving the screw 1465 to rotate is provided on the outer wall of the picking plate 1461; the servo motor three 1466 drives the two adjusting blocks 1463 to move toward each other or in opposite directions through the screw 1465, thereby adjusting the distance between the two air claws 1464.

[0037] like Figure 10 and Figure 11 and Figure 12 The servo motor 2 144 drives the electric cylinder 3 145 to rotate, and then drives the two air claws 1464 to rotate, changing the direction of the two air claws 1464. The structure of the telescopic plate 146 can be a transversely distributed box body fixed to the piston rod of the electric cylinder 3 145. The longitudinal section of the box body is a rectangular frame. A removal plate is slidably connected to the box body. The bottom of the box body is provided with an electric cylinder 5 that pushes the removal plate to slide in the box body. The removal plate is fixedly connected to the picking plate 1461 at one end of the box mouth of the removal box body.

[0038] like Figure 10 and Figure 11 and Figure 12The vertical plate 14 is provided with a placement box 15 for placing injection molded parts on one side of the vertical plate 14 where the take-out box 141 is provided.

[0039] like Figure 10 and Figure 11 and Figure 12 The storage box 11 and the storage box 2 12 are respectively located on both sides of the electric cylinder 3 145, and the upper end surface of the workbench 1 is provided with a U-shaped bracket 16 for lifting the storage box 11 away from the upper end surface of the workbench 1. The two vertical sides of the bracket 16 are fixedly connected to the upper end surface of the workbench 1. The storage box 11 includes two storage boxes 111 fixed on the horizontal surface of the bracket 16. The inner wall of the storage box 111 slides with the copper bushing 4. At this time, the axis of the copper bushing 4 is horizontally distributed. The storage boxes 111 are vertically distributed and a removal hole 112 for removing the bottom layer of the copper bushing 4 is opened on the bottom box wall. The outer wall of the storage box 111 is provided with a transversely distributed cylinder 113, and a push pin 114 is slidably connected to the cylinder 113. The push pin 114 also slides with the hole wall of the removal hole 112, and the end of the push pin 114 that moves into and out of the removal hole 112 is provided with a plug 115 that cooperates with the inner wall of the copper bushing 4. The front end of the plug 115 is tapered to facilitate the insertion of the plug 115 into the copper bushing 4. The horizontal surface of the bracket 16 is provided with an electric cylinder 4 116 that pushes the push pin 114 to move back and forth in the cylinder 113. The electric cylinder 4 116 is located on the side of the storage box 111 away from the air gripper 1464; like Figure 10 and Figure 11 and Figure 12 , when the upper end of the storage box 111 is connected to the diverter box 117 with a conical distribution and the accumulation box 118 located at the upper end of the diverter box 117 and connected to the diverter box 117, the upper end of the diverter box 117 has a large taper, and the internal width of the diverter box 117, the accumulation box 118, and the storage box 111 is the width of the copper bushing 4, that is, the copper bushing 4 can be placed in the accumulation box 118 and the diverter box 117 and the storage box 111 with the axis horizontal. At this time, multiple copper bushings 4 are placed in the accumulation box 118 and the diverter box 117, and the diverter box 117 is opened. The function of box 117 is to guide multiple copper bushings 4 in the accumulation box 118 to be arranged vertically in sequence into the storage box 111, so that the copper bushings 4 can fall into the removal hole 112 in sequence from top to bottom along the height direction of the storage box 111, and then the electric cylinder 116 pushes the push pin 114 to move toward the copper bushing 4 until the plug post 115 is inserted into the copper bushing 4. As the push pin 114 moves, the push pin 114 will drive the copper bushing 4 to move out of the storage box 111, making it easier for the air claw 1464 to grab the copper bushing 4 on the plug post 115.

[0040] like Figure 10 and Figure 11 and Figure 12The working principle of the picking component is as follows: after the lower mold 2 after injection molding is rotated away from the upper mold 3, the positioning rod 236 and the lifting plate 231 are both distributed toward the air gripper 1464, and the electric cylinder 3 145 drives the air gripper 1464 to move downward. At the same time, the servo motor 3 1466 adjusts the distance between the two air grippers 1464, so that the two air grippers 1464 grab the outer wall of the injection molded part opposite to the placement cylinder 2461, and then the telescopic plate 146 drives the two air grippers 1464 to move horizontally away from the positioning rod 236 until the injection molded part is pulled out of the positioning rod 236. Then, the servo motor 2 144 drives the electric cylinder 3 145 to rotate 180°, that is, to rotate away from the storage box 11, so that the air gripper 1464 is located above the placement box 15, thereby facilitating the air gripper 1464 to place the injection molded part into the placement box 15 for storage. like Figure 10 and Figure 11 and Figure 12 The electric cylinder 4 116 pushes the push post 114 to move toward the copper bushing 4, so that the push post 114 will drive the copper bushing 4 to move out of the storage box 111. The servo motor 2 144 drives the electric cylinder 3 145 to continue to rotate 90 degrees, so that the air claw 1464 is facing the two copper bushings 4 to be moved out. The telescopic plate 146, the electric cylinder 3 145, and the servo motor 3 1466 cooperate to make the two air claws 1464 grab the two copper bushings 4. At this time, the two copper bushings 4 that have been moved out of the storage box 111 are The distance between the copper bushings 4 is the distance between the two positioning rods 236 on the lower mold 2, so that after the air gripper 1464 grabs the copper bushing 4, it directly rotates 270° in the opposite direction so that the air gripper 1464 faces the positioning rod 236 on the lower mold 2. The telescopic plate 146 enables the two air grippers 1464 to insert the copper bushing 4 onto the two positioning rods 236, thereby completing the automatic installation of the two copper bushings 4; in the above process, it is also necessary to manually take out the slider 246 and install the pin 5.
