[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] Example 1

[0042] like Figures 1 to 10 As shown, the fully automatic injection molding process for connecting terminals according to an embodiment of the present invention comprises the following specific steps:

[0043] Step 1: Raw material preparation: Select appropriate plastic raw materials and perform pretreatment, drying, and color mixing to ensure the quality of the raw materials and the progress of injection molding;

[0044] Step 2: Injection molding: The pretreated plastic raw material is added to 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, filling the mold cavity and forming the preliminary shape of the connecting terminal. The plastic in the mold gradually cools and solidifies under the action of the cooling system to form the connecting terminal.

[0045] As Figures 1 to 4 shown, the injection molding machine of the embodiment comprises a box body 1, the upper surface of the box body 1 is provided with a first hydraulic cylinder 2, the output end of the first hydraulic cylinder 2 is fixedly connected with a forming hydraulic plate 21, the upper surface of the box body 1 is fixedly connected with an air pump 22, one side of the air pump 22 is fixedly connected with a conveying tank 24, one side of the conveying tank 24 is fixedly connected with a hydraulic conveying pipe 23, one end of the hydraulic conveying pipe 23 away from the conveying tank 24 is fixedly connected with an auxiliary plate 25, the forming hydraulic plate 21 and the auxiliary plate 25 abut to form a forming mold, and one side of the box body 1 is provided with a discharging port 26; one side of the box body 1 is fixedly connected with a first shell 27, the first shell 27 is provided with a collecting frame 28, the collecting frame 28 is used for collecting connecting terminals, the inside of the first shell 27 is provided with a conveying belt 29, and the conveying belt 29 is used for conveying the collecting frame 28; a first frame body 3 is fixedly connected to the inside of the box body 1 corresponding to the position of the discharging port 26, a collecting groove 31 is formed in the first frame body 3, a plurality of discharging holes 34 are formed in the bottom surface of the first frame body 3, and the plurality of discharging holes 34 are used for discharging the connecting terminals, and a plurality of conical portions 35 are fixedly connected to the bottom surface of the first frame body 3, and the plurality of conical portions 35 are used for assisting the connecting terminals to be discharged.

[0046] Specifically, in the process of using the terminal forming injection molding machine, first, the two mold plates are spliced, after splicing, the heated tank is connected with the hydraulic conveying pipe 23 under the action of the air pump 22, then the hydraulic conveying pipe 23 will pass the plastic fluid into the mold between the two mold plates, and the connecting terminals between the two mold plates are cooled and formed, then the mold plates are opened, the connecting terminals and the injection molded frame are ejected together through the ejector pin in one of the mold plates, then fall into the storage box, but because the mold plate injection molding has connecting terminals and a forming frame, the volume of the forming frame is large, which 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, the internal space utilization is low, the quality is not enough, the storage box cannot be pressed down due to gravity, so that the replacement work is carried out, and the connecting terminals and the forming frame in the storage box also need to be screened separately, causing the problem of complicated processing process;

[0047] Therefore, the application solves the problem by setting a certain structure. First, pour the prepared plastic raw material into the conveying tank 24. Through the heating and shearing action of the screw in the conveying tank 24, 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 output end of the forming hydraulic plate 21 to approach the auxiliary plate 25. In the process of approaching the auxiliary plate 25, the auxiliary plate 25 will also gradually approach the forming hydraulic plate 21 under the push of the hydraulic conveying pipe 23, until the forming hydraulic plate 21 and the auxiliary plate 25 abut, thereby forming a connecting terminal forming mold. After the forming mold is formed, the air pump 22 is started to pressurize the conveying tank 24. The plastic fluid in the conveying tank 24 will flow quickly into the forming mold along the hydraulic conveying 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 the connecting terminal. After cooling is completed, the first hydraulic cylinder 2 and the hydraulic conveying pipe 23 are started to drive the forming hydraulic plate 21 and the auxiliary plate 25 to separate, respectively. Then the connecting terminal and the forming frame will fall into the first frame 3, and then the falling connecting terminal will be screened by the first frame 3 and fall into the collecting frame 28 along the discharge port 26 on one side of the box 1. However, the formed frame is stuck in the first frame 3, which achieves the separation of the formed frame and the connecting terminal, improves the processing efficiency, and reduces the production cost.

[0048] The model plate injection molding has a connecting terminal and a forming frame. The volume of the forming frame is large, which occupies a large space in the storage box, so that the connecting terminal may overflow after being stored for a certain period of time, the internal space utilization is low, the quality is not enough, and the storage box cannot be pressed down due to gravity.

[0049] As shown in Figure 6 The first frame 3 of the embodiment is fixedly connected with a rotating shaft 315 on one side. The rotating plate 32 is rotatably connected to the circumferential surface of the rotating shaft 315. The second hydraulic cylinder 37 is fixedly connected to the inside of the box 1. The output end of the second hydraulic cylinder 37 is fixedly connected with a fixed column 38. One end of the fixed column 38 is fixedly connected with a positioning plate 311. The lower surface of the positioning plate 311 is slidably provided with a vibrating member. The vibrating member includes a plurality of vertical rods 312 slidably arranged on the lower surface of the positioning plate 311.

[0050] Specifically, the rotating plate 32 is arranged on the rotating shaft 315 on one side of the first frame body 3, which prevents the falling connecting terminals and the forming frame from falling out of the first frame body 3, and the forming frame needs to be taken out of the first frame body 3 after falling into the first frame body 3 to avoid that the forming frame blocks the connecting terminals to be discharged from the first frame body 3, so that the fixed column 38 at the output end of the second hydraulic cylinder 37 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, and the movement of the positioning plate 311 triggers the vibration member on the lower surface of the positioning plate 311, so as to shake the pushed forming frame and shake the connecting terminals that may not be detached from the forming frame, thereby improving the detachment effect of the connecting terminals and the falling efficiency of the connecting terminals.

[0051] As shown in Figure 8 , the vibration member further includes a first groove 320 formed in the lower surface of the positioning plate 311, a sliding plate 321 slidably connected in the first groove 320, a compression spring 322 fixedly connected to one end of the sliding plate 321, the other end of the compression spring 322 fixedly connected to the inner wall of the positioning plate 311, a plurality of vertical rods 312 fixedly connected to the lower surface of the sliding plate 321, a plurality of horizontal rods 313 fixedly connected to one side of the plurality of vertical rods 312, a protrusion 323 fixedly connected to the other end of the sliding plate 321, a limiting plate 318 fixedly connected to one side of the first frame body 3 corresponding to the protrusion 323, and a plurality of protruding plates 319 fixedly connected to one side of the limiting plate 318.

[0052] Specifically, during the sliding process of the positioning plate 311 pushed by the fixed column 38, the sliding plate 321 in the first groove 320 on the lower surface of the positioning plate 311 drives the protrusion 323 at one end thereof to slide along the protruding plates 319 on the inner wall of the first frame body 3, and when the protrusion 323 encounters the protruding plates 319, it is first pressed along the inclined surface of the protruding plates 319, at which time the sliding plate 321 moves to the side with the compression spring 322, thereby driving the plurality of horizontal rods 313 and vertical rods 312 on the lower surface of the sliding plate 321 to move, and then when the protrusion 323 moves into the groove between the two protruding plates 319, the compression spring 322 rebounds and repeatedly moves, thereby forming a back-and-forth shaking motion to shake and detach the connecting terminals that have not been detached from the forming frame.

[0053] As shown in Figure 6 , one side of the rotating plate 32 is fixedly connected with a pressure sensor 33, and the position corresponding to the pressure sensor 33 of the positioning plate 311 is fixedly connected with a top column 314 made of rubber for pressing and protecting the pressure sensor 33.

[0054] Specifically, after the shaped frame inserted into the vertical rod 312 and the horizontal rod 313 is moved to one side of the rotating plate 32, the top post 314 fixed on one side of the positioning plate 311 extrudes the pressure sensor 33 on one side of the rotating plate 32, and then the device automatically rotates the rotating plate 32 around the rotating shaft 315, and after rotating 180 degrees, the shaped frame can be pushed out of the first frame body 3, achieving the cleaning of the shaped frame.

[0055] As shown in Figure 5 , the circumferential surface of the fixed column 38 is fixedly connected with the fixed plate 39, one side of the fixed plate 39 is fixedly connected with a plurality of insertion rods 310, the first frame body 3 is provided with a connecting groove 36 corresponding to the position of the insertion rod 310, and the insertion rod 310 can be inserted into the connecting groove 36 for the stirring of the connecting terminal.

[0056] Specifically, after the fixed column 38 drives the positioning plate 311 at one end to clean the shaped frame, the fixed plate 39 on the circumferential surface of the fixed column 38 also moves towards the first frame body 3, and the insertion rod 310 on one side of the fixed plate 39 is inserted into the first frame body 3 along the connecting groove 36, and the insertion rod 310 stirs the connecting terminal stuck between the tapered columns in the first frame body 3, so that the connecting terminal can fall into the discharging hole 34, thereby improving the falling efficiency of the connecting terminal and the processing efficiency.

[0057] As shown in Figure 7 , the two sides of each insertion rod 310 are provided with a plurality of second grooves 324, each second groove 324 is fixedly connected with a fixed shaft 325, a torsional spring 326 is sleeved on the circumferential surface of each fixed shaft 325, and a push rod 327 is fixedly connected on the circumferential surface of each torsional spring 326.

[0058] Specifically, after the insertion rod 310 is inserted into the first frame body 3, the push rod 327 in the second groove 324 on both sides of the insertion rod 310 is limited between every two conical columns 35, thereby passively rotating, and then the push rod 327 is reset under the driving of the torsional spring 326 after being separated from the two conical columns 35, and when the stirring is completed once, the push rod 327 on both sides of each insertion rod 310 can be retracted into the second groove 324 through electric control, and then retracted along with the second hydraulic cylinder 37, thereby achieving the unblocking and falling of the connecting terminal, and the reciprocating use.

[0059] As shown in Figure 6 , both ends of the rotating plate 32 are fixedly connected with the insertion plate 316, one side of the first frame body 3 is provided with two insertion grooves 317, and the two insertion plates 316 can be inserted into the insertion grooves 317 for the stable insertion of the rotating plate 32 and the first frame body 3.

[0060] Specifically, in the process of rotating the rotating plate 32, both ends of the rotating plate 32 are fixedly connected with the inserting plates 316, and in the process of closing and sealing the first frame body 3 by the rotating plate 32, the two inserting plates 316 can be inserted into the two inserting grooves 317, so that the stable insertion of the rotating plate 32 and the first frame body 3 is achieved.

[0061] Embodiment Two

[0062] As shown in Figures 2 to 10 the comparative embodiment one, another embodiment of the present application is that a fixing groove 5 is formed in the inner top wall of the box body 1, a third hydraulic cylinder 52 is fixedly connected to the top wall of the fixing groove 5, the output end of the third hydraulic cylinder 52 is fixedly connected to a bottom plate 53, and 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 discharging the forming frame.

[0063] 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, and then pushes out the first frame body 3, when the positioning plate 311 moves to the position directly below the fixing groove 5, the third hydraulic cylinder 52 in the fixing groove 5 is started, and after the third hydraulic cylinder 52 is started, the output end of the third hydraulic cylinder 52 drives the bottom plate 53 to move downward, and then the downward movement of the bottom plate 53 drives the plurality of clamping plates 51 on the lower surface to move downward, the clamping plates 51 are located between every two vertical rods 312, and move downward along the positioning plate 311, and then the second hydraulic cylinder 37 retracts the positioning plate 311, so that the forming frame is pushed and falls off, and the screening effect of the forming frame and the connecting terminal is improved.

[0064] As shown in Figure 10 the comparative embodiment one, another embodiment of the present application is that a fixing groove 5 is formed in the inner top wall of the box body 1, a third hydraulic cylinder 52 is fixedly connected to the top wall of the fixing groove 5, the output end of the third hydraulic cylinder 52 is fixedly connected to a bottom plate 53, and 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 discharging the forming frame.

[0065] Specifically, the placing box 4 and the storage groove 43 in the box body 1 are used to store the forming frame, the first motor 42 is driven to rotate, and then the first motor 42 drives the reciprocating screw 44 to rotate, the reciprocating screw 44 drives the extrusion plate 45 connected therewith to reciprocate in the placing box 4, and the forming frame is effectively crushed and extruded, the efficiency of material processing is improved, the burden of manual screening of the connecting terminal and the forming frame is reduced, and the process of crushing and extruding is helpful to reduce the volume of the material, facilitate subsequent storage and recycling, and improve the space utilization.

[0066] The working principle is that first, the prepared plastic raw material is poured into the conveying tank 24, and through the heating and shearing action of the screw in the conveying tank 24, 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 output end of the forming hydraulic plate 21 to approach the auxiliary plate 25. In the process of approaching the auxiliary plate 25, the auxiliary plate 25 will also gradually approach the forming hydraulic plate 21 under the push of the hydraulic conveying pipe 23, until the forming hydraulic plate 21 and the auxiliary plate 25 abut, thereby forming a connecting terminal forming mold. After the forming mold is formed, the air pump 22 is started to pressurize the conveying tank 24, and the plastic fluid in the conveying tank 24 will flow quickly into the forming mold along the hydraulic conveying 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 the connecting terminal. After cooling is completed, the first hydraulic cylinder 2 and the hydraulic conveying pipe 23 are started to drive the forming hydraulic plate 21 and the auxiliary plate 25 to separate, respectively. Then the connecting terminal and the forming frame will fall into the first frame body 3, and then the falling connecting terminal will fall into the collecting frame 28 through the screening of the first frame body 3 along the discharge port 26 on one side of the box body 1, but the formed frame is stuck in the first frame body 3, achieving the separation of the formed frame and the connecting terminal.

[0067] Then the second hydraulic cylinder 37 is started to drive the fixed column 38 at the output end to move along the first frame body 3. The vertical rods 312 on the lower surface of the positioning plate 311 on one end of the fixed column 38 can push the formed frame out of the first frame body 3. In the process of sliding of the positioning plate 311 pushed by the fixed column 38, the slide plate 321 at one end of the first groove 320 on the lower surface of the positioning plate 311 will drive the lug 323 to slide along the lug plate 319 on the inner wall of the first frame body 3. When the lug 323 encounters the lug plate 319, it will be first squeezed along the inclined surface of the lug plate 319. At this time, the slide plate 321 will move to the side with the compression spring 322, thereby driving the horizontal rods 313 and vertical rods 312 on the lower surface of the slide plate 321 to move. Then, when the lug 323 moves into the groove between the two lug plates 319, the compression spring 322 rebounds, and continuously reciprocates, thereby forming a back-and-forth shaking action, which can shake off the connecting terminal that has not fallen off the formed frame, thereby improving the falling efficiency of the connecting terminal, improving the processing efficiency, and reducing the production cost.

[0068] After the positioning plate 311 on one end of the fixed column 38 cleans the formed frame, the fixed plate 39 on the circumference of the fixed column 38 will also move towards the first frame body 3. The insertion rod 310 on one side of the fixed plate 39 will be inserted into the first frame body 3 along the connecting slot 36, thereby disturbing the connecting terminal stuck between the tapered columns in the first frame body 3, so that the connecting terminal can fall into the discharge hole 34, thereby improving the falling efficiency of the connecting terminal and further improving the processing efficiency.

[0069] When the insertion rod 310 is inserted into the first frame body 3, the push rod 327 in the second groove 324 on both sides of the insertion rod 310 is limited between every two conical parts 35, thereby passively rotating, and then disengaging between the two conical parts 35, and the push rod 327 is reset under the driving of the torsional spring 326. After completing a push, the push rod 327 on both sides of each insertion rod 310 can be retracted into the second groove 324 through electric control, and then retracted along with the retraction of the second hydraulic cylinder 37, so as to achieve the purpose of dredging the falling of the connecting terminal and continuously reciprocating use.

[0070] When the positioning plate 311 pushes the horizontal rod 313 and the vertical rod 312 to push the shaped frame in the first frame body 3, the shaped frame is clamped, and then the first frame body 3 is pushed out. When the positioning plate 311 moves to the position directly below the fixed groove 5, the third hydraulic cylinder 52 in the fixed groove 5 is started, and the third hydraulic cylinder 52 is started to drive the output end bottom plate 53, and the downward movement of the bottom plate 53 can drive the plurality of clamping plates 51 on the lower surface. The clamping plate 51 is located between every two vertical rods 312 and moves downward along the positioning plate 311, and then the second hydraulic cylinder 37 retracts the positioning plate 311, so as to achieve the purpose of pushing and falling of the shaped frame, and improve the screening effect of the shaped frame and the connecting terminal.

[0071] Finally, the shaped frame is stored through the placement box 4 and the storage groove 43 in the box body 1, and then the first motor 42 is driven to rotate, and then the first motor 42 drives the reciprocating screw rod 44 to rotate. The reciprocating screw rod 44 drives the sliding connection of the extrusion plate 45 in the placement box 4 to reciprocate, and effectively crushes and extrudes the shaped frame, improves the efficiency of material processing, reduces the burden of manual screening of the connecting terminal and the shaped frame, and at the same time, the process of extrusion and crushing helps to reduce the volume of the material, facilitates subsequent storage and recycling, and improves the space utilization rate.
