Description

Technical Field

[0001] This utility model belongs to the field of injection molding equipment technology, and in particular relates to an injection molding machine for inner and outer molds of a charging cable connector. Background Technology

[0002] The existing production process of charging cable connectors is usually carried out through injection molds. The manufacturing process of charging cable connectors is usually divided into inner mold injection molding and outer mold injection molding, which requires two injection molding processes of adhesive layers. Vertical injection molding machines are usually used for the injection molding of adhesive layers of charging cable connectors.

[0003] An injection molding machine is a molding device that produces various plastic products from thermoplastic or thermosetting plastics through processes such as heating, melting, injection, pressure holding, and cooling. The most distinctive feature of a vertical injection molding machine is that the injection system and the mold clamping system move perpendicular to the ground; that is, the injection screw moves up and down, and the mold clamping mechanism typically opens and closes vertically as well.

[0004] In existing technologies, the vertical stroke of a vertical injection molding machine is superimposed, such as... Figure 1 As shown, the C-shaped frame provides more stable support. However, since the actions of mold closing, mold locking, and pressure holding of the injection molding machine all need to be installed on the upper part of the C-shaped frame, the width of the C-shaped frame is increased. This results in the injection molding machine occupying a large space and obstructing the view during the injection molding of the charging cable connector adhesive layer, thus affecting production efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 2 The diagram shown is a structural diagram of an inner and outer mold injection molding machine for a charging cable connector 3 provided in an embodiment of the present utility model, including: a frame 1, wherein the frame 1 is provided with a mounting boss 11 located at the center position; A set of injection molding devices 2, the set of injection molding devices 2 are respectively used for inner mold injection and outer mold injection of the charging cable 3 connector, and the set of injection molding devices 2 are all installed on the mounting boss 11 and located on adjacent injection positions. The injection molding device 2 includes an injection assembly 21 and a mold assembly 22. The injection assembly 21 is connected to the mold assembly 22 via a mounting bracket 23. The mounting bracket 23 includes a mounting plate 232 and a guide rod 233. The mounting plate 232 is provided with a positioning sleeve 231, which is used to position the injection assembly 21. One end of the positioning sleeve 231 is connected to the guide rod 233, and the other end of the guide rod 233 passes through the mounting boss 11 and is connected to the movable mold 222 of the mold assembly 22.

[0020] In this embodiment of the present invention, preferably, the inner and outer mold injection molding machine for the charging cable 3 connector is mainly used for the injection molding of the inner mold rubber layer and the outer mold rubber layer for the two connectors of the charging cable 3. The inner mold rubber layer is used to protect the wire core at the connector, and the outer mold rubber layer is used for the outer rubber layer of the charging cable 3 connector. Since the rubber materials for the inner and outer mold injection are different, the inner mold rubber layer and the outer mold rubber layer of the charging cable 3 connector are respectively injection molded by a set of injection molding devices 2. The frame 1 can be the base part of the entire inner and outer mold injection molding machine for the charging cable 3 connector. A mounting boss 11 with a certain height is provided at the center of the upper surface of the frame 1. A set of injection molding devices 2 are respectively installed on the mounting boss 11 and located on adjacent injection positions, so that they are located directly above the carrier 121 on the turntable 12. The turntable 12 is set on the frame 1 and is used to drive the charging cable 3 on the carrier 121 to rotate so as to transport the charging cable 3 to the corresponding injection position of the set of injection molding devices 2. Preferably, a group of injection molding units 2 arranged side by side can reduce their space occupation and provide loading and unloading space on both sides of the injection molding unit 2. The injection molding unit 2 is connected between the injection assembly 21 and the mold assembly 22 via a mounting bracket 23. The top surface of the mounting plate 232 is used to position the moving position of the injection assembly 21 via a positioning sleeve 231. A guide rod 233 is connected to the positioning sleeve 231 and passes through the mounting boss 11 to connect to the moving mold 222 of the mold assembly 22. The guide rod 233 guides the movement of the moving mold 222 of the mold assembly 22. The mounting bracket 23 connects the structural components of the injection, mold closing, and mold moving actions of the injection molding unit 2. This reduces the width of the injection molding unit 2, thereby reducing the width of the C-shaped structure of the injection molding unit 2, making the installation layout of a group of injection molding units 2 more compact and avoiding low production efficiency caused by large space occupation obstructing the view and affecting the loading and unloading speed. Figure 1 As shown, the C-shaped structure of the injection molding device 2 mainly refers to the fact that the mold assembly 22 and the injection assembly 21 together form a vertical shape similar to the English letter "C" in spatial layout. It is a single open frame with huge load-bearing capacity and rigidity, which is integrally cast or welded. This frame connects the moving mold 222 of the mold assembly 22 and the mounting boss 11 of the frame 1. When viewed from the side, it forms a "C" shape. The mold assembly 22 performs mold closing, injection, cooling and mold opening within this open "C" shaped area.

[0021] In one embodiment of this utility model, a mounting boss 11 is provided at the center of the frame 1. A carrier 121 for placing charging cables 3 is transported by a turntable 12 rotating around the mounting boss 11, so that the carrier 121 moves to the inner mold injection position and the outer mold injection position respectively for inner mold injection and outer mold injection of the charging cable 3 connector. A set of injection molding devices 2 are respectively installed on the mounting boss 11 and positioned in adjacent injection positions to facilitate inner mold injection and outer mold injection of different sets of charging cables 3. The injection molding devices 2 installed on the mounting boss 11 are connected between the injection assembly 21 and the mold assembly 22 by a mounting bracket 23, and a positioning sleeve 231 is installed on the user The mounting plate 232 for mounting the injection assembly 21 facilitates the positioning of the injection assembly 21. A guide rod 233 connects the positioning sleeve 231 and the mold assembly 22, guiding the movement of the moving mold 222 of the mold assembly 22. A mounting bracket 23 connects the injection assembly 21 and the mold assembly 22, using the positioning sleeve 231 to position the injection assembly 21. The guide rod 233 guides the movement of the moving mold 222, facilitating the installation of various moving structural components and reducing the overall width of the injection molding device 2. This reduces the space occupied by one set of injection molding devices 2, and the installation of one set of injection molding devices 2 at adjacent injection positions further reduces space requirements and facilitates loading and unloading, thereby improving production efficiency.

[0022] like Figure 3-4 As shown, in a preferred embodiment of the present invention, the injection assembly 21 includes an injection drive 211 and a melting assembly. The injection drive 211 is mounted on a mounting frame 212 and is used to push the rubber material in the melting cylinder 215 to be injected into the mold cavity. The mounting frame 212 has a U-shaped structure. The middle part of the mounting frame 212 is used to mount the injection drive 211. The ends of the two side wings of the mounting frame 212 are respectively connected to the melting assembly. The melt assembly includes a melt motor 213 and a melt cylinder 215. The melt motor 213 is mounted on a mounting block 214 and is used to drive the screw inside the melt cylinder 215 to rotate. The mounting block 214 is sleeved on the two side wings of the mounting frame 212 and is located above the positioning sleeve 231. The two side wings of the mounting frame 212 are collinear with the axis of the guide rod 233 inserted into the positioning sleeve 231. The two side wings of the mounting frame 212 are used to guide the movement of the mounting block 214 and the melt assembly.

[0023] In this embodiment of the present invention, preferably, the injection assembly 21 of the injection molding device 2 mainly uses the injection drive 211 to push the melting assembly, so that the molten rubber in the melting cylinder 215 is injected into the mold cavity. The injection drive 211 can be a hydraulic cylinder. The injection drive 211 is mounted on the top surface of the U-shaped mounting bracket 212. The output end of the injection drive 211, i.e., the end of the piston rod, passes through the through hole in the middle of the mounting bracket 212, so that it is positioned above the melting motor 213, so that the rubber in the melting cylinder 215 is injected into the mold cavity during the movement of the screw. The screw inside the melting cylinder 215 is driven to rotate to agitate and transport the molten adhesive. The melting cylinder 215 can be installed at the center of the mounting plate 232 of the mounting bracket 23. A hopper 216 is provided on the outer side of the melting cylinder 215 near the melting motor 213 and is connected to the inside of the melting cylinder 215 so that the adhesive can enter the melting cylinder 215 through the hopper 216. A heating coil can be provided on the outer wall of the melting cylinder 215 so that the adhesive inside the melting cylinder 215 is in a molten state. The melting cylinder 215 is located below the mounting block 214.

[0024] The two wing rods of the mounting bracket 212 are respectively inserted into the top surface of the mounting block 214. The center of the top surface of the mounting block 214 is used to install the melt motor 213. The mounting block 214 is provided with a connecting frame connected to the output end of the injection drive 211. The connecting frame is also located at the center of the mounting block 214 and covers the outside of the melt motor 213. The connecting frame and the mounting block 214 are fixedly connected. When the injection drive 211 drives the connecting frame, the mounting block 214 and the melt motor 213 connected to the mounting block 214 to move through the output end, the mounting block 214 moves along the length direction of the two wing rods of the mounting bracket 212 and the positioning sleeve 231 restricts the stroke of the mounting block 214. It also drives the screw connected to the output end of the melt motor 213 to move, so that the screw pushes the glue in the melt cylinder 215 into the mold cavity. The middle part of the mounting block 214 and the mounting bracket 212 can be a narrow plate shape with the same length, thereby reducing the width space occupied by the injection molding device 2.

[0025] like Figure 1-4 As shown in the preferred embodiment of this utility model, the mounting plate 232 is H-shaped, and a first positioning hole for positioning the melting cylinder 215 of the injection component 21 is provided at the center of the mounting plate 232. A set of positioning sleeves 231 are provided and arranged at two opposite corners of the top surface of the mounting plate 232. A set of guide rods 233 are provided, and a set of guide rods 233 are respectively connected to the bottom surface of the mounting plate 232 through the mounting sleeves. The guide rods 233 are used to guide the movement of the mounting plate 232 and the injection component 21.

[0026] In this embodiment of the present invention, preferably, the mounting plate 232 located on the mounting block 214 and used for mounting the melt cylinder 215 is H-shaped. One end of the melt cylinder 215 is mounted on the top surface of the mounting plate 232 via a connecting seat, and the other end of the melt cylinder 215 passes through the mounting plate 232 so that it is positioned above the moving mold 222. The mounting plate 232 is provided with positioning sleeves 231 at two opposite corners for connecting the wing rods on both sides of the mounting frame 212. The positioning sleeves 231 are fitted over the wing rods on both sides of the mounting frame 212. The mounting bracket 212 is located below the mounting block 214. The ends of the two wing rods on both sides of the mounting bracket 212 can be fixedly connected to the top surface of the mounting plate 232. The guide rod 233 is fitted with a mounting sleeve on its outer side. The mounting sleeve is installed on the bottom surface of the mounting plate 232 and the axis of the mounting sleeve is collinear with the axis of the positioning sleeve 231. One end of the guide rod 233 is installed on the bottom surface of the mounting plate 232 and the other end of the guide rod 233 is installed on the back of the moving mold 222. The length of the diagonal connecting line of the mounting plate 232 can be the same as the length of the mounting block 214.

[0027] like Figure 3-5 As shown in the preferred embodiment of the present invention, the injection molding device 2 further includes a mold closing assembly. The mold closing assembly includes a set of mold locking drive members 24. The set of mold locking drive members 24 is mounted on the mounting boss 11. The set of mold locking drive members 24 are respectively close to both sides of the mounting plate 232 and located at two opposite openings of the mounting plate 232. The output ends of the set of mold locking drive members 24 are respectively connected to the moving mold 222 of the mold assembly 22. The set of mold locking drive members 24 is used to drive the moving mold 222 to move to realize the opening or closing of the mold cavity.

[0028] In this embodiment of the present invention, preferably, the injection molding device 2 further includes a mold closing assembly mounted on the mounting boss 11. The mold closing assembly mainly uses a set of mold locking drive members 24 to drive the moving mold 222 of the mold assembly 22 and the injection assembly 21 mounted on the mounting plate 232 to move, so that the moving mold 222 and the positioning mold 221 close together to realize the closing, opening and locking actions of the mold cavity. The set of mold locking drive members 24 can be located at the two openings of the H-shaped mounting plate 232 and mounted on the mounting boss 11. The mold locking drive members 24 can be selected as hydraulic cylinders, utilizing the liveness of their output ends. The stopper rod passes through the mounting boss 11 and connects to the movable mold 222 of the mold assembly 22. Since the guide rod 233 is connected between the mounting plate 232 and the movable mold 222, when the output end of the mold clamping drive 24 extends or retracts, it will drive the movable mold 222, the mounting plate 232 connected to the guide rod 233, and the injection assembly 21 mounted on the mounting plate 232 to move along the length direction of the guide rod 233. The extension can cause the movable mold 222 to move toward the positioning mold 221 to achieve mold closing. The retraction can cause the movable mold 222 to separate from the positioning mold 221 after injection molding is completed.

[0029] like Figure 3-6As shown, in a preferred embodiment of the present invention, the mold assembly 22 includes a positioning mold 221, a moving mold 222 and a set of moving drive components 223. The positioning mold 221 is mounted on the frame 1 and located outside the turntable 12. The positioning mold 221 is provided with a first positioning cavity 2211 and a plurality of second positioning cavities 2212. The first positioning cavity 2211 is used to position the carrier 121, and the plurality of second positioning cavities 2212 are used to position the charging cable 3 on the carrier 121. The back of the movable mold 222 is connected to the guide rod 233. The back of the movable mold 222 is provided with a feed port, which is used for the glue material in the melt cylinder 215 to enter the mold cavity. The front of the movable mold 222 is provided with a third positioning cavity and a fourth positioning cavity. The third positioning cavity is used to position the carrier 121, and the fourth positioning cavity is used to position the charging cable 3 on the carrier 121. A set of movable drive components 223 are mounted on the mounting plate 232. The set of movable drive components 223 are arranged at two opposite corners on the top surface of the mounting plate 232. The output end of the set of movable drive components 223 is connected to the top surface of the movable mold 222. The set of movable drive components 223 is used to drive the movable mold 222 to move so as to adjust the distance between the melt cylinder 215 and the feed port on the back of the movable mold 222.

[0030] In this embodiment of the present invention, preferably, the positioning mold 221 of the mold assembly 22 is mounted on the frame 1 and located outside the turntable 12. The closing surface of the positioning mold 221 faces the moving mold 222 located above it. A carrier 121 is positioned on the positioning mold 221 by a strip-shaped first positioning cavity 2211 so that when the mold is closed, the carrier 121 is positioned on the first positioning cavity 2211. A plurality of second positioning cavities 2212 can be placed one-to-one with a plurality of charging cables 3 on the carrier 121. A tool for... The circular groove of the positioning moving mold 222 is designed to engage with the protrusion on the moving mold 222 to achieve complete mold closing; the moving mold 222, which is connected to the guide rod 233 and the output end of the mold locking drive component 24, can also be provided with a feed hole that penetrates the mold closing surface. The feed port is located on the back of the moving mold 222, and the discharge port is located on the mold closing surface, so that the rubber material enters the mold cavity after mold closing. A third positioning cavity corresponding to the first positioning cavity 2211 of the positioning mold 221 and a fourth positioning cavity corresponding to the second positioning cavity 2212 are provided on the mold closing surface of the moving mold 222. A set of moving drive components 223 are installed at two opposite corners on the top surface of the mounting plate 232. The output end of the moving drive component 223 can be a piston rod, the end of which is connected to the back of the moving mold 222 to drive the moving mold 222 to move and adjust the distance between the feed port on the back of the moving mold 222 and the material outlet of the melt cylinder 215 on the bottom surface of the mounting plate 232. This can drive the moving mold 222 closer to or further away from the material outlet of the melt cylinder 215. When it is closer, it can facilitate the material to enter the mold cavity after the moving mold 222 and the positioning mold 221 are closed through the feed port. When it is further away, it can stop the material discharge after the injection is completed. The distance between the melt cylinder 215 and the back of the moving mold 222 increases, preventing the material outlet of the melt cylinder 215 from being too close to the moving mold 222, so that the vibration during disassembly will collide with the material outlet of the melt cylinder 215. It can also facilitate the cleaning action of the material outlet of the melt cylinder 215. Moreover, the set of moving drive components 223 are respectively installed at two opposite corners on the top surface of the mounting plate 232, which can reduce the width of the injection molding device 2 and the space occupied.

The support column 111 is installed at the center of the top surface of the frame 1. The support column 111 is connected to the bottom surface of the mounting platform 112. The mounting platform 112 is plate-shaped. A set of positioning grooves is provided on the side of the mounting platform 112. The set of positioning grooves are used to position the melt cylinder 215 of the injection assembly 21. The mounting platform 112 is provided with a plurality of limiting holes for limiting the radial movement of the guide rod 233. The mold closing assembly of the injection molding device 2 is installed on the top surface of the mounting platform 112, and the output end of the mold clamping drive 24 passes through the mounting hole of the mounting platform 112 and is connected to the moving mold 222.

[0032] In this embodiment of the present invention, preferably, the mounting boss 11 mounted on the upper surface of the frame 1 supports the mounting platform 112 and a set of injection molding devices 2 mounted on the mounting platform 112 via support columns 111. The support columns 111 and the upper surface of the frame 1 can be integral or fixed to the upper surface of the frame 1. The mounting platform 112 can be a plate with a certain thickness, and positioning grooves are respectively provided on its adjacent two sides. Mounting holes for mounting the output end of the mold clamping drive 24 are respectively provided on both sides of the positioning grooves. The positioning groove located between the two mounting holes is used to position the melt. The cylinder 215 is arranged so that a set of clamping drive components 24 are close to the molten cylinder 215. This installation layout can reduce the space occupied by the injection molding device 2 in the width direction. A limiting hole with the axis close to the support column 111 is provided on the mounting platform 112. The limiting hole restricts the radial movement freedom of the guide rod 233 and reduces the space occupied by the injection molding device 2 in the outward direction, so that its center of gravity is close to the support column 111. At the same time, the clamping force when the moving mold 222 and the positioning mold 221 are closed is more concentrated and closer to the mounting platform 112. This not only reduces the space occupied, but also avoids the clamping force deviating from the center of gravity and affecting the clamping effect.
