The current connecting terminals are mainly composed of two parts: a conductive sheet and a plastic shell. The conductive sheet is responsible for achieving electrical connection, while the plastic shell plays the role of fixing and protecting the conductive sheet. The plastic shell is usually manufactured using injection molding technology.

[0004] In the process of using the above-mentioned terminal molding injection molding machine, the two model plates are first spliced ​​together. After splicing, the heating tank passes the heated and molten plastic fluid into the hydraulic delivery pipe under the action of the air pump, and then the hydraulic delivery pipe passes the plastic fluid into the mold between the two model plates. After the connecting terminal between the two model plates is cooled and formed, the two model plates are opened, and the connecting terminal and its injection-molded molding frame are pushed down together by the ejector pin in one of the model plates, and then fall into the storage box. However, since the model plate is injection-molded with connecting terminals and molding frames, the molding frame is large in size and will occupy a large space in the storage box, so that the connecting terminals may overflow after being stored for a certain period of time, but the internal space utilization rate is small and the quality is insufficient, resulting in the storage box being unable to be pressed down by gravity, so as to be replaced.

[0020] 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 explained below in conjunction with specific implementation methods.

[0021] Embodiment 1 like Figures 1 to 10 As shown, a fully automatic injection molding process for connecting terminals according to an embodiment of the present invention specifically comprises the following steps: Step 1: Raw material preparation: Select appropriate plastic raw materials, and pre-treat, dry, and mix colors to ensure the quality of the raw materials and the progress of injection molding; Step 2: Injection molding: Add the pretreated plastic raw materials into the hopper of the injection molding machine. Through heating and the shearing action of the screw, the plastic is melted and reaches the set injection temperature. The injection molding machine injects the molten plastic into the mold at high pressure and speed to fill the mold cavity and form the preliminary shape of the connecting terminal. The plastic in the mold is gradually cooled and solidified under the action of the cooling system to form a connecting terminal.

[0022] like Figures 1 to 4 As shown, the injection molding machine of this embodiment includes a box body 1, a first hydraulic cylinder 2 is arranged on the upper surface of the box body 1, a forming hydraulic plate 21 is fixedly connected to the output end of the first hydraulic cylinder 2, an air pump 22 is fixedly connected to the upper surface of the box body 1, a delivery tank 24 is fixedly connected to one side of the air pump 22, a hydraulic delivery pipe 23 is fixedly connected to one side of the delivery tank 24, an auxiliary plate 25 is fixedly connected to the end of the hydraulic delivery pipe 23 away from the delivery tank 24, the forming hydraulic plate 21 and the auxiliary plate 25 are abutted to form a forming mold, and a feeding port 26 is opened on one side of the box body 1; a first shell 24 is fixedly connected to one side of the box body 1 A collecting frame 28 is arranged on the first shell 27, and the collecting frame 28 is used to collect the connecting terminals. A conveyor belt 29 is arranged inside the first shell 27, and the conveyor belt 29 is used to convey the collecting frame 28. A first frame body 3 is fixedly connected to a position corresponding to the discharge port 26 inside the box body 1, and a collecting groove 31 is provided in the first frame body 3. A plurality of discharge holes 34 are provided on the bottom surface of the first frame body 3, and the plurality of discharge holes 34 are used to drop the connecting terminals. A plurality of cones 35 are fixedly connected to the bottom surface of the first frame body 3, and the plurality of cones 35 are used to assist in the discharge of the connecting terminals.

[0023] Specifically, in the process of using the above-mentioned terminal molding injection molding machine, the two model plates are first spliced ​​together. After the splicing, the heating tank passes the heated and molten plastic fluid into the hydraulic delivery pipe 23 under the action of the air pump 22, and then the hydraulic delivery pipe 23 passes the plastic fluid into the mold between the two model plates. After the connecting terminal between the two model plates is cooled and formed, the two model plates are opened, and the connecting terminal and its injection-molded molding frame are pushed down together by the ejector in one of the model plates, and then fall into the storage box. However, since the model plate is injection-molded with the connecting terminal and the molding frame, the molding frame is large in size and will occupy a large space in the storage box, so that the connecting terminal may overflow after being stored for a certain period of time, but the internal space utilization rate is small and the quality is insufficient, resulting in the storage box being unable to be pressed down by gravity, so as to perform replacement work. At the same time, it is also necessary to screen the connecting terminal and the molding frame in the storage box separately, resulting in the problem of cumbersome processing process; Therefore, the present invention solves this problem by setting a certain structure. First, the prepared plastic raw material is poured into the conveying tank 24. After being heated in the conveying tank 24 and sheared by the screw, the plastic is melted and reaches the set injection molding temperature. After the plastic reaches the preset temperature, the first hydraulic cylinder 2 is started to drive the molding hydraulic plate 21 at its output end to approach the auxiliary plate 25. In the process of approaching the auxiliary plate 25, the auxiliary plate 25 will gradually approach the molding hydraulic plate 21 under the push of the hydraulic conveying pipe 23 until the molding hydraulic plate 21 and the auxiliary plate 25 abut against each other, thereby forming a connecting terminal molding mold. After the molding mold is formed, the air pump 22 is started to pressurize the conveying tank 24, and the plastic fluid in the conveying tank 24 is It will quickly flow into the molding mold along the hydraulic delivery pipe 23, fill the mold cavity and form the preliminary shape of the connecting terminal. The plastic in the mold is gradually cooled and solidified under the action of the cooling system to form a connecting terminal. After the cooling is completed, the first hydraulic cylinder 2 and the hydraulic delivery pipe 23 are started to drive the molding hydraulic plate 21 and the auxiliary plate 25 to separate respectively, and then the connecting terminal and the molding frame will fall into the first frame 3. Then, the connection terminal that falls off at this time will pass through the screening of the first frame 3 and fall into the collection frame 28 along the discharge port 26 on one side of the box body 1, but the molded frame is stuck in the first frame 3, so that the molding frame and the connecting terminal are separated, the processing efficiency is improved, and the production cost is reduced; The invention solves the problem that, since the injection-molded model plate has connecting terminals and a molding frame, the molding frame is large in size and occupies a large space in the storage box, so that the connecting terminals may overflow after being stored for a certain period of time, but the internal space utilization rate is low and the quality is insufficient, resulting in the storage box being unable to be pressed down by gravity.

[0024] like Figure 6As shown, in this embodiment, a rotating shaft 315 is fixedly connected to one side of the first frame body 3, and a rotating plate 32 is rotatably connected to the circumferential surface of the rotating shaft 315. A second hydraulic cylinder 37 is fixedly connected to the inside of the box body 1, and a fixed column 38 is fixedly connected to the output end of the second hydraulic cylinder 37. One end of the fixed column 38 is fixedly connected to a positioning plate 311, and a vibration member is slidably provided on the lower surface of the positioning plate 311. The vibration member includes a plurality of vertical rods 312 slidably provided on the lower surface of the positioning plate 311.

[0025] Specifically, a rotating plate 32 is arranged on the rotating shaft 315 on one side of the first frame 3 to rotate. The arrangement of the rotating plate 32 prevents the falling connecting terminals and the forming frame from falling out of the first frame 3. At the same time, after the forming frame falls into the first frame 3, the forming frame in the first frame 3 needs to be taken out to avoid the forming frame blocking the first frame 3 from unloading the connecting terminals. Therefore, the second hydraulic cylinder 37 is started to drive the fixed column 38 at its output end to move along the first frame 3. Several vertical rods 312 on the lower surface of the positioning plate 311 at one end of the fixed column 38 can push the forming frame out of the first frame 3. At the same time, the movement of the positioning plate 311 will trigger the vibration part on the lower surface of the positioning plate 311, thereby shaking the pushed forming frame, and vibrating and falling off the connecting terminals that may not have fallen off on the forming frame, thereby improving the falling effect of the connecting terminals and improving the falling efficiency of the connecting terminals.

[0026] like Figure 8 As shown, the vibration member of this embodiment also includes a first groove body 320 opened on the lower surface of the positioning plate 311, and a slide plate 321 is slidably connected in the first groove body 320, one end of the slide plate 321 is fixedly connected to a compression spring 322, one end of the compression spring 322 is fixedly connected to the inner wall of the positioning plate 311, a plurality of vertical rods 312 are fixedly connected to the lower surface of the slide plate 321, one side of each of the plurality of vertical rods 312 is fixedly connected to a plurality of horizontal rods 313, and a protrusion 323 is fixedly connected to the other end of the slide plate 321, and a side of the first frame body 3 corresponding to the protrusion 323 is fixedly connected to a limiting plate 318, and one side of the limiting plate 318 is fixedly connected to a plurality of protrusions 319.

[0027] Specifically, when the positioning plate 311 is pushed to slide by the fixed column 38, the slide plate 321 in the first groove 320 on the lower surface of the positioning plate 311 will drive the protrusion 323 at one end thereof to slide along the protrusion 319 on the inner wall of the first frame body 3. When the protrusion 323 encounters the protrusion 319, it will first be squeezed along the inclined surface of the protrusion 319. At this time, the slide plate 321 will move toward the side with the compression spring 322, thereby driving the movement of several horizontal bars 313 and vertical bars 312 on the lower surface of the slide plate 321. Then, when the protrusion 323 moves into the groove between the two protrusions 319, the compression spring 322 rebounds and keeps reciprocating, thereby forming a back and forth shaking action, thereby achieving the work of shaking and falling off the connecting terminals that have not fallen off on the forming frame.

[0028] like Figure 6 As shown, in this embodiment, a pressure sensor 33 is fixedly connected to one side of the rotating plate 32 , and a top column 314 is fixedly connected to the position of the positioning plate 311 corresponding to the pressure sensor 33 . The top column 314 is made of rubber and is used to squeeze and protect the pressure sensor 33 .

[0029] Specifically, after the forming frame is inserted with the cooperation of the vertical rod 312 and the horizontal rod 313, it moves to one side of the rotating plate 32. Through the top column 314 fixed on one side of the positioning plate 311, the top column 314 will squeeze the pressure sensor 33 on one side of the rotating plate 32, and then the equipment will automatically rotate the rotating plate 32 around the rotating axis 315. After rotating 180 degrees, the formed frame can be pushed out of the first frame body 3, thereby cleaning the forming frame.

[0030] like Figure 5 As shown, the circumferential surface of the fixed column 38 of this embodiment is fixedly connected to a fixed plate 39, and a plurality of plug rods 310 are fixedly connected to one side of the fixed plate 39. A connecting groove 36 is opened at the position of the first frame 3 corresponding to the plug rod 310, and the plurality of plug rods 310 can be inserted into the connecting groove 36 for moving the connecting terminal.

[0031] Specifically, after the fixed column 38 drives the positioning plate 311 at one end thereof to clean the forming frame, the fixed plate 39 on the circumferential surface of the fixed column 38 will also move toward the first frame body 3, and the insertion rod 310 on one side of the fixed plate 39 will be inserted into the first frame body 3 along the connecting groove 36. The connecting terminal stuck between the conical columns in the first frame body 3 is disturbed by the insertion rod 310, so that the connecting terminal can flow into the discharge hole 34, thereby improving the falling efficiency of the connecting terminal and further improving the processing efficiency.

[0032] like Figure 7 As shown, in this embodiment, a plurality of second grooves 324 are provided on both sides of each insertion rod 310, a fixed shaft 325 is fixedly connected in each second groove 324, a torsion spring 326 is sleeved on the circumferential surface of each fixed shaft 325, and a shift rod 327 is fixedly connected to the circumferential surface of each torsion spring 326.

[0033] Specifically, after the insertion rod 310 is inserted into the first frame 3, the levers 327 in the second grooves 324 on both sides of the insertion rod 310 will be limited between every two cones 35, thereby passively rotating, and then the levers 327 will be reset under the drive of the torsion spring 326 after being separated from between the two cones 35. After one shifting is completed, the levers 327 on both sides of each insertion rod 310 can be retracted into the second grooves 324 through electrical control, and then retracted as the second hydraulic cylinder 37 is retracted, thereby achieving the goal of being able to clear the falling of the connection terminals and being able to be used repeatedly.

[0034] like Figure 6 As shown, in this embodiment, both ends of the rotating plate 32 are fixedly connected with plug plates 316, and one side of the first frame body 3 is provided with two slots 317, and the two plug plates 316 can be inserted into the slots 317 to assist the stable insertion of the rotating plate 32 and the first frame body 3.

[0035] Specifically, during the rotation of the rotating plate 32, both ends of the rotating plate 32 are fixedly connected with plug plates 316. During the closing of the rotating plate 32 to seal the first frame 3, the two plug plates 316 can be inserted into the two slots 317, thereby achieving stable insertion of the auxiliary rotating plate 32 and the first frame 3.

[0036] Embodiment 2 like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is: a fixing groove 5 is opened on the internal top wall of the box body 1, a third hydraulic cylinder 52 is fixedly connected to the top wall of the fixing groove 5, an output end of the third hydraulic cylinder 52 is fixedly connected to a bottom plate 53, a plurality of clamping plates 51 are fixedly connected to the lower surface of the bottom plate 53, and the plurality of clamping plates 51 are used to assist in the blanking of the forming frame.

[0037] Specifically, when the positioning plate 311 pushes the horizontal rod 313 and the vertical rod 312 to clamp the forming frame in the first frame body 3, the first frame body 3 is pushed out. When the positioning plate 311 moves to the bottom of the fixing groove 5, the third hydraulic cylinder 52 in the fixing groove 5 is started. After the third hydraulic cylinder 52 is started, it will drive the bottom plate 53 at the output end. Then, the downward movement of the bottom plate 53 can drive several clamping plates 51 on the lower surface. The clamping plates 51 will be located between every two vertical rods 312 and move downward along the positioning plate 311. Then, the second hydraulic cylinder 37 retracts the positioning plate 311, which can achieve the effect of moving and falling off the forming frame, thereby improving the screening effect of the forming frame and the connecting terminal.

[0038] like Fig.10 As shown, in this embodiment, a placement box 4 is provided inside the box body 1, and a storage slot 43 is opened in the placement box 4. A support plate 41 is fixedly connected to one side of the box body 1, and a first motor 42 is fixedly connected to the upper surface of the support plate 41. A reciprocating screw 44 is fixedly connected to the output end of the first motor 42, and an extrusion plate 45 is slidably connected to the circumferential surface of the reciprocating screw 44. The reciprocating screw 44 and the extrusion plate 45 are both located inside the placement box 4, and the extrusion plate 45 is used for crushing and extruding the forming frame.

[0039] Specifically, the forming frame is stored through the placement box 4 and the storage slot 43 in the box body 1, and then the first motor 42 is driven to rotate, and then the first motor 42 will drive the reciprocating screw 44 to rotate, and the reciprocating screw 44 drives the extrusion plate 45 slidably connected to it to reciprocate in the placement box 4, so as to effectively crush and extrude the forming frame, thereby improving the efficiency of material processing and reducing the burden of manual screening of connection terminals and forming frames. At the same time, the extrusion and crushing process helps to reduce the volume of materials, facilitates subsequent storage and recycling, and improves space utilization.

[0040] Working principle: first, pour the prepared plastic raw material into the conveying tank 24. After heating in the conveying tank 24 and the shearing action of the screw, the plastic is melted and reaches the set injection temperature. After the plastic reaches the preset temperature, the first hydraulic cylinder 2 is started to drive the molding hydraulic plate 21 at its output end to approach the auxiliary plate 25. In the process of approaching the auxiliary plate 25, the auxiliary plate 25 will gradually approach the molding hydraulic plate 21 under the push of the hydraulic conveying pipe 23 until the molding hydraulic plate 21 and the auxiliary plate 25 abut against each other, thereby forming a connecting terminal molding mold. After the molding mold is formed, the air pump 22 is started to pressurize the conveying tank 24, and the plastic fluid in the conveying tank 24 is It will quickly flow into the molding mold along the hydraulic delivery pipe 23, fill the mold cavity and form the preliminary shape of the connecting terminal. The plastic in the mold is gradually cooled and solidified under the action of the cooling system to form a connecting terminal. After the cooling is completed, the first hydraulic cylinder 2 and the hydraulic delivery pipe 23 are started to drive the forming hydraulic plate 21 and the auxiliary plate 25 to separate respectively, and then the connecting terminal and the molding frame will fall into the first frame 3. Then, the connection terminal that falls off at this time will pass through the screening of the first frame 3 and fall into the collection frame 28 along the discharge port 26 on one side of the box body 1, but the molded frame is stuck in the first frame 3, so that the molding frame and the connecting terminal are separated; Then, by starting the second hydraulic cylinder 37, the fixed column 38 at its output end is driven to move along the first frame body 3, and the plurality of vertical rods 312 on the lower surface of the positioning plate 311 at one end of the fixed column 38 can push the forming frame out of the first frame body 3. In the process of the positioning plate 311 being pushed and slid by the fixed column 38, the slide plate 321 in the first groove 320 on the lower surface of the positioning plate 311 will drive the protrusion 323 at one end thereof to slide along the protrusion plate 319 on the inner wall of the first frame body 3. When the protrusion 323 encounters the protrusion plate 319, it will first When pressed along the inclined surface of the convex plate 319, the slide plate 321 will move toward the side with the compression spring 322, thereby driving the plurality of cross bars 313 and the vertical bars 312 on the lower surface of the slide plate 321 to move, and then when the convex block 323 moves into the groove between the two convex plates 319, the compression spring 322 rebounds and continuously reciprocates, thereby forming a back-and-forth shaking action, so as to achieve the work of shaking off the connection terminals that have not fallen off on the forming frame, thereby improving the falling efficiency of the connection terminals, improving the processing efficiency, and reducing the production cost; After the fixing column 38 drives the positioning plate 311 at one end thereof to clean the forming frame, the fixing plate 39 on the circumferential surface of the fixing column 38 will also move toward the first frame body 3, and the insertion rod 310 on one side of the fixing plate 39 will be inserted into the first frame body 3 along the connecting groove 36, and the connecting terminal stuck between the cone columns in the first frame body 3 is disturbed by the insertion rod 310, so that the connecting terminal can flow into the feeding hole 34, thereby improving the falling efficiency of the connecting terminal, thereby improving the processing efficiency; After the insertion rod 310 is inserted into the first frame 3, the levers 327 in the second grooves 324 on both sides of the insertion rod 310 are limited between each two cones 35, so that they rotate passively, and then the levers 327 are reset under the drive of the torsion spring 326 after being separated from between the two cones 35. After one shifting, the levers 327 on both sides of each insertion rod 310 can be retracted into the second grooves 324 by electric control, and then retracted with the retraction of the second hydraulic cylinder 37, so that the connection terminal can be unblocked and dropped, and it can be used repeatedly; When the positioning plate 311 pushes the cross bar 313 and the vertical bar 312 to clamp the forming frame in the first frame body 3, the first frame body 3 is pushed out, and when the positioning plate 311 moves to the right below the fixing groove 5, the third hydraulic cylinder 52 in the fixing groove 5 is started. After the third hydraulic cylinder 52 is started, it will drive the output end bottom plate 53, and then the downward movement of the bottom plate 53 can drive a number of card plates 51 on the lower surface, and the card plates 51 will be located between every two vertical bars 312 and move downward along the positioning plate 311. Then, the second hydraulic cylinder 37 retracts the positioning plate 311, which can achieve the effect of moving and falling off the forming frame, thereby improving the screening effect of the forming frame and the connecting terminal. Finally, the forming frame is stored through the placement box 4 and the storage slot 43 in the box body 1, and then the first motor 42 is driven to rotate, and then the first motor 42 will drive the reciprocating screw 44 to rotate, and the reciprocating screw 44 drives the extrusion plate 45 slidably connected to it to reciprocate in the placement box 4, so as to effectively crush and extrude the forming frame, thereby improving the efficiency of material processing and reducing the burden of manual screening of connection terminals and forming frames. At the same time, the extrusion and crushing process helps to reduce the volume of materials, facilitates subsequent storage and recycling, and improves space utilization.
