Technical Field
[0001] This application relates to the technical field of injection molding machines, and in particular, to a two-shot injection molding device. Background Art
[0002] Plastic molding, also known as injection molding, is a method in which plastic materials are completely melted by a screw stirrer at a certain temperature and then injected into a mold cavity under high pressure. After cooling and solidifying, a molded product is obtained. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a variety of colors and patterns, the shape can range from simple to complex, the size can range from large to small, and the product size is precise, the product is easy to update, and it can form complex parts. Injection molding is suitable for mass production and molding processing fields of complex-shaped products.
[0003] Currently, as Figure 1 shown in the plug socket, a wire is connected to the plug socket, and the two-shot insulating layer of the plug socket is usually produced by an injection molding machine. An injection molding machine generally includes an upper mold and a lower mold. The lower mold is fixed on the frame of the injection molding machine, and the upper mold can be lifted and is communicated with the raw material supply port of the injection molding machine.
[0004] In view of the above related technologies, when the existing injection molding machine performs two-shot injection on the plug socket, it adopts a single-shot injection mode. After each injection is completed, the staff needs to manually take out the finished product and install a new plug socket for the next injection, which cannot achieve fast and continuous production, affecting production efficiency and production cost, so it needs to be improved. Utility Model Content
[0005] In order to improve the continuity of two-shot injection production of the plug socket and improve production efficiency, this application provides a two-shot injection molding device.
[0006] A two-shot injection molding device provided by this application adopts the following technical solutions:
[0007] A two-shot injection molding device includes a frame, an upper mold, an injection base, a lower mold, and a driving member. The upper mold is arranged to be lifted on the frame. The injection base is arranged on the frame and is located on the moving path of the upper mold. The lower mold is detachably connected to the injection base and there are two of them. The lower mold is used for installing the plug socket. The driving member is connected to the upper mold and is used to control the movement of the upper mold.
[0008] By adopting the above technical solutions, the upper mold is designed to be a liftable structure and is communicated with the raw material supply port of the injection molding machine. The driving member controls the lifting of the upper mold to achieve the mold closing or mold opening operation with the lower mold. The lower mold is designed to be a quickly detachable structure, which is convenient for quick replacement.
[0009] During injection molding, the operator installs the plug base on one of the lower molds and places it on the injection molding base. Then, the driving member is used to control the movement of the upper mold and close the mold with the lower mold. During the injection molding process, the operator can continue to pre-install the plug base on the other lower mold. After the injection molding is completed, the other lower mold with the installed plug base is replaced on the injection molding base; at the same time, the lower mold that has completed the injection molding is removed, and the finished product is taken out. Then, the plug base to be rubber-coated is reinstalled on this lower mold for the next use. By adopting the structure of two alternately used lower molds, continuous production is achieved, greatly improving the production efficiency and reducing the labor cost and operation difficulty.
[0010] Preferably, a limiting groove is formed on the injection molding base, and the lower mold is located in the limiting groove.
[0011] By adopting the above technical solution, the limiting groove can play a role in limiting the lower mold and improve the stability when the lower mold and the upper mold are closed.
[0012] Preferably, handles are further connected to both ends of the lower mold.
[0013] By adopting the above technical solution, the presence of the handles can facilitate the operator to apply force to the lower mold, thereby controlling the installation and disassembly of the lower mold.
[0014] Preferably, a placement plate is further included. The placement plate is connected to the frame and is close to the injection molding base. The placement plate is used for placing the lower mold.
[0015] By adopting the above technical solution, the placement plate can provide corresponding space for placing the lower mold.
[0016] Preferably, a suspension chain and a hook are further included. One end of the suspension chain is connected to the frame, and the other end is connected with the hook. The hook is used for hanging the wires of the plug base.
[0017] By adopting the above technical solution, the plug bases to be rubber-coated in a pile can be hung on the hook, so that the operator can insert the plugs of the plug bases into the lower mold, reducing the time consumed by moving the plug bases back and forth. At the same time, the suspension chain is flexible and can flexibly adjust the position of the hook to meet the production requirements.
[0018] Preferably, a plurality of insertion blocks are connected to the injection molding base, and a plurality of insertion holes are formed on the lower mold. When the lower mold is connected to the injection molding base, each of the insertion blocks is respectively inserted into each of the insertion holes.
[0019] By adopting the above technical solution, the insertion blocks and the insertion holes cooperate with each other, and rely on the insertion force to improve the installation stability of the lower mold, and at the same time do not affect the detachable property of the lower mold.
[0020] Preferably, a guiding post is connected to one side of the upper mold facing the injection molding base, and a guiding hole for inserting the guiding post is correspondingly formed in the injection molding base. When the upper mold and the lower mold are closed, the guiding post is inserted into the guiding hole.
[0021] By adopting the above technical solution, when the upper mold gradually approaches the lower mold, the guiding post will gradually extend into the guiding hole. The guiding post and the guiding hole cooperate with each other to guide and limit the movement of the upper mold, improving the accuracy of mold closing.
[0022] Preferably, the driving member is a cylinder, an oil cylinder or an electric push rod.
[0023] By adopting the above technical solution, a cylinder, an oil cylinder or an electric push rod can be used to control the linear movement of the upper mold and exert a pressure on the lower mold.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] (1) By providing two detachable lower molds, it is convenient for quick switching, realizing continuous production and greatly improving production efficiency.
[0026] (2) By providing a handle, the presence of the handle can facilitate the staff to apply force to the lower mold, thereby controlling the installation and disassembly of the lower mold.
[0027] (3) By providing a lifting chain and a hook, the plug sockets to be coated with glue in piles can be hung on the hook, so that the staff can insert the plugs of the plug sockets into the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS

Without conflict, those skilled in the art can combine and combine the different embodiments or examples represented in this application and the features of different embodiments or examples.
[0037] An embodiment of this application discloses a plastic injection molding device with overmolding. Referring to Figure 2 and Figure 3 , the injection molding device includes a frame 1, an upper mold 2, an injection molding base 3, a lower mold 4, and a driving member 5. The frame 1 serves as a carrier and is fixedly installed on the ground. The upper mold 2 is arranged to move up and down in the vertical direction on the frame 1. The injection molding base 3 is installed on the frame 1 and is located directly below the upper mold 2. The injection molding base 3 is on the moving path of the upper mold 2. The lower mold 4 is detachably connected to the injection molding base 3, and there are two of them. The lower mold 4 is used for installing the plug base. In this embodiment, the plug of the plug base is inserted into the lower mold 4. The driving member 5 is connected to the upper mold 2 and is used to control the up and down movement of the upper mold 2. The driving member 5 is a cylinder, an oil cylinder, or an electric push rod. The cylinder, the oil cylinder, or the electric push rod can all be used to control the linear movement of the upper mold 2, and can be specifically selected according to actual production requirements.
[0038] Among them, several guide posts 6 are fixedly connected to one side of the upper mold 2 facing the injection base 3, and corresponding guide holes 7 for the guide posts 6 to insert are formed on the injection base 3. When the upper mold 2 gradually approaches the lower mold 4, the guide posts 6 will gradually extend into the guide holes 7. The guide posts 6 and the guide holes 7 cooperate with each other to guide and limit the movement of the upper mold 2, improving the accuracy of mold closing. After the upper mold 2 and the lower mold 4 are closed, each guide post 6 is respectively inserted into each guide hole 7.
[0039] During injection molding, the staff installs the plug socket on one of the lower molds 4 and places it on the injection base 3. Then, the driving member 5 is used to control the movement of the upper mold 2 to close the mold with the lower mold 4. During the injection molding process, the staff can continue to pre-install the plug socket on the other lower mold 4. After the injection molding is completed, the other lower mold 4 with the plug socket installed is replaced onto the injection base 3; at the same time, the lower mold 4 that has been injection molded is removed, and the finished product is taken out. Then, the plug socket to be rubber-coated is reinstalled on this lower mold 4 for the next use. By adopting the structure of two alternately used lower molds 4, continuous production is realized, greatly improving the production efficiency and reducing the labor cost and operation difficulty.
[0040] Specifically, a limiting groove 8 is formed on the base, and the lower mold 4 is located in the limiting groove 8. The limiting groove 8 can limit the lower mold 4, improving the stability when the lower mold 4 and the upper mold 2 are closed. Several inserting blocks are also connected to the injection base 3, and several inserting holes 9 are formed on the lower mold 4; when the lower mold 4 is connected to the injection base 3, each inserting block is respectively inserted into each inserting hole 9. Among them, handles 10 are fixedly connected to both ends of the lower mold 4. The presence of the handles 10 can facilitate the staff to apply force to the lower mold 4, thereby controlling the installation and disassembly of the lower mold 4. In some embodiments, a placing plate 11 is also fixedly installed on the frame 1. The placing plate 11 is horizontally arranged and close to the injection base 3. The placing plate 11 is used for placing the lower mold 4 and can provide a relatively large operating space for the staff to operate.
[0041] In addition, referring to Figure 2 , a hanging chain 12 and a hook 13 are also installed on the frame 1. One end of the hanging chain 12 is fixedly connected to the frame 1, and the other end hangs freely and is fixedly connected with the hook 13. The hook 13 is used for hanging the plug socket to be rubber-coated. A pile of plug sockets to be rubber-coated can be hung on the hook 13, so that the staff can insert the plug of the plug socket into the lower mold 4, reducing the time consumed by moving the plug socket back and forth. At the same time, the hanging chain 12 is flexible and can flexibly adjust the position of the hook 13 to meet the production requirements.
[0042] The implementation principle of an encapsulation injection molding device according to an embodiment of the present application is as follows: The upper mold 2 is designed to be a liftable structure and is communicated with the raw material supply port of the injection molding machine; the lower mold 4 is designed to be a quickly detachable structure for easy and quick replacement. During injection molding, the staff installs the plug socket on one of the lower molds 4 and places it on the injection molding base 3. Then, the driving member 5 is used to control the movement of the upper mold 2 to close the mold with the lower mold 4. During the injection molding process, the staff can continue to pre-install the plug socket on the other lower mold 4. After the injection molding is completed, the other lower mold 4 with the plug socket already installed is replaced onto the injection molding base 3; at the same time, the lower mold 4 that has been injection molded is removed, and the finished product is taken out. Then, the plug socket to be encapsulated is reinstalled on this lower mold 4 for the next use. By adopting the structure of two alternately used lower molds 4, continuous production is achieved, and the production efficiency is improved.
[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
