Description

Technical Field

[0001] This utility model relates to the field of plastic preform processing technology, and in particular to a lightweight injection molding component for Vitamil bottle preforms. Background Technology

[0002] Lightweighting of Vitasoy bottle preforms refers to reducing the amount of raw materials used and the weight of the preforms by optimizing the wall thickness distribution and structural design, while ensuring that the original structural strength, sealing performance and usability of the Vitasoy bottle preforms are not affected. This method can not only save production costs, but also reduce resource consumption and environmental pollution. Injection molding components are the core parts used in the injection molding process to achieve the injection molding of bottle preforms. They mainly consist of mold cavities, cores, sprue bushings, ejection mechanisms, etc. In the production process of Vitamil bottle preforms, molten plastic raw materials need to be injected into the cavity of the injection molding component. After cooling and solidification, the required bottle preform is obtained. Therefore, injection molding components are key equipment for achieving mass production and efficient production of bottle preforms.

[0003] The existing lightweight injection-molded component for Vitamil bottle preform has the following shortcomings: Because traditional mold cavity modules and fixed templates are mostly fixedly connected, it is not convenient to replace mold cavity modules with different wall thicknesses. As a result, when processing Vitamil bottle preforms for lightweighting, the entire mold needs to be replaced, which is cumbersome and costly. At the same time, the existing equipment has low cooling efficiency due to unreasonable cooling structure design. The heat absorbed by the coolant is difficult to dissipate quickly, resulting in slow cooling and shaping of the bottle preforms, which affects production efficiency. Utility Model Content

[0004] This utility model mainly provides a lightweight injection molding component for Vita milk bottle preforms that is easy to replace mold cavity modules and has high cooling efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight injection molding component for Vita milk bottle preform, comprising a fixed template and a movable template, wherein the movable template is disposed on the right side of the fixed template, an injection tube is fixedly connected to the top left side of the fixed template, a plurality of mold cores are fixedly installed on the left side of the movable template, a plurality of mold cavity modules are fixedly installed on the right side of the fixed template, and cooling components are fixedly connected to both the front and rear sides of the fixed template.

[0006] The mold cavity module includes a plug-in post. Several plug-in slots are provided on the right side of the fixed mold plate. The plug-in post is slidably inserted into the inner surface of the plug-in slot. A mold cavity body is provided in the middle of the plug-in post. A sprue sleeve is provided in the middle of the left end of the inner surface of the plug-in slot. The left end of the mold cavity body is connected to the sprue sleeve. Grooves are provided at the four corners of the right end of the plug-in post. Threaded rods are fixedly connected to the four corners of the inner wall of the plug-in slot. The right end of the threaded rod penetrates into the interior of the groove and a threaded cap is threadedly connected to its outer surface.

[0007] Preferably, positioning slide bars are fixedly connected to the front and rear sides of the right side of the inner wall of the insertion slot, and positioning slide grooves are opened on the front and rear sides of the right side of the outer surface of the insertion post, and the inner surface of the positioning slide groove is slidably connected to the outer surface of the positioning slide bar.

[0008] Preferably, the cooling assembly includes a connecting frame, and two connecting frames are respectively fixedly connected to the front and rear sides of the fixed template. Dustproof nets are fixedly connected to the upper and lower ends of the inner surface of the connecting frame.

[0009] Preferably, a plurality of metal heat pipes are provided on the opposite sides of the two connecting frames. The metal heat pipes penetrate the interior of the fixed template and are respectively located on the inner side of the two connecting frames at their front and rear ends. Heat dissipation fins are fixedly connected to the front and rear sides of the outer surface of the metal heat pipes, and the heat dissipation fins are fixedly connected to the inner side of the connecting frames.

[0010] Preferably, a support frame is fixedly connected to the top of the inner surface of the connecting frame, an electric motor is fixedly connected to the middle of the support frame, a rotating shaft is fixedly connected to the output shaft of the electric motor, and a guide fan is fixedly connected to the top of the outer surface of the rotating shaft.

[0011] Preferably, the bottom end of the rotating shaft passes through a metal heat pipe and a plurality of guide fans are fixedly connected to its outer surface, and the guide fans are rotatably connected inside the metal heat pipe.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, the mold cavity module is quickly disassembled and precisely replaced by slidingly engaging the insertion post of the mold cavity module with the insertion slot of the fixed template, combined with the fixing structure of the threaded rod and threaded cap, and the guiding and positioning functions of the positioning slide bar and positioning groove. When lightweight processing of Vitamil bottle preforms is required, the threaded cap is unscrewed to release the insertion post from its restriction, the old mold cavity module is pulled out along the positioning slide bar, and then the new mold cavity module with a smaller wall thickness is inserted by aligning it with the positioning slide bar through the positioning groove. Finally, the threaded cap is tightened to complete the fixation. This structure solves the problem of the difficulty in replacing the traditional fixed mold cavity. It can produce bottle preforms with different degrees of lightweighting without replacing the entire mold. It not only simplifies the operation process and reduces equipment investment costs, but also improves the flexibility and adaptability of production, and meets the diverse needs of lightweight processing.

[0013] 2. In this utility model, the electric motor of the cooling component drives the rotating shaft, which in turn drives the guide fan inside the metal heat pipe and the guide fan inside the connecting frame to rotate. Together with the heat transfer structure of the heat dissipation fins and the metal heat pipe, a highly efficient cooling circulation system is formed. The rotation of the guide fan causes the coolant to circulate rapidly within the metal heat pipe, absorbing the heat from the mold plate and the mold cavity. The heat is transferred to the heat dissipation fins through the metal heat pipe, and the rotation of the guide fan accelerates the airflow within the connecting frame, quickly dissipating the heat from the heat dissipation fins to the outside. Compared with traditional cooling methods, this structure significantly improves heat exchange efficiency, accelerates the cooling and shaping speed of the preform, shortens the production cycle, ensures cooling uniformity, reduces quality problems such as preform deformation caused by insufficient cooling, and improves product qualification rate and production efficiency.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figure 1 - Figure 4This utility model provides a technical solution: a lightweight injection molding assembly for Vita milk bottle preforms, including a fixed template 1 and a movable template 2. The movable template 2 is located on the right side of the fixed template 1. An injection tube 3 is fixedly connected to the top left side of the fixed template 1. Several mold cores 4 are fixedly installed on the left side of the movable template 2. Several mold cavity modules 5 are fixedly installed on the right side of the fixed template 1. Cooling components 6 are fixedly connected to both the front and rear sides of the fixed template 1. The mold cavity module 5 includes a plug-in post 51. An opening is provided on the right side of the fixed template 1. There are several insertion slots 11. Insertion pins 51 are slidably inserted into the inner surface of the insertion slots 11. A mold cavity body 52 is provided in the middle of the insertion pin 51. A sprue sleeve is provided in the middle of the left end of the inner surface of the insertion slot 11. The left end of the mold cavity body 52 is connected to the sprue sleeve. Grooves 53 are provided at the four corners of the right end of the insertion pin 51. Threaded rods 12 are fixedly connected to the four corners of the inner wall of the insertion slot 11. The right end of the threaded rod 12 passes through the interior of the groove 53 and a threaded cap 54 is threadedly connected to its outer surface.

[0019] like Figure 2 As shown, positioning slide bars 13 are fixedly connected to the front and rear sides of the right side of the inner wall of the insertion groove 11. Positioning grooves 55 are provided on the front and rear sides of the right side of the outer surface of the insertion post 51. The inner surface of the positioning groove 55 is slidably connected to the outer surface of the positioning slide bar 13. Here, the cooperation between the positioning slide bar 13 and the positioning groove 55 can achieve precise positioning during the installation of the mold cavity module 5, avoid misalignment between the mold cavity body 52 and the sprue sleeve due to installation offset, and ensure smooth injection of the injection molding material.

[0020] like Figure 3 As shown, the cooling component 6 includes a connecting frame 61. Two connecting frames 61 are fixedly connected to the front and rear sides of the fixed template 1, respectively. Dustproof nets 62 are fixedly connected to the upper and lower ends of the inner surface of the connecting frame 61. Here, the dustproof nets 62 can block external dust from entering the interior of the connecting frame 61, prevent dust from adhering to the heat dissipation components and affecting the cooling effect, and at the same time ensure the cleanliness of airflow.

[0021] like Figure 3 As shown, several metal heat pipes 63 are provided on the opposite sides of the two connecting frames 61. The metal heat pipes 63 penetrate the interior of the fixed template 1 and are respectively located on the inner side of the two connecting frames 61 at both ends. Heat dissipation fins 64 are fixedly connected to the front and rear sides of the outer surface of the metal heat pipes 63. The heat dissipation fins 64 are fixedly connected to the inner side of the connecting frames 61. Here, the metal heat pipes 63 quickly conduct heat from the fixed template 1 and the mold cavity module 5. The heat dissipation fins 64 accelerate heat dissipation and improve cooling efficiency by increasing the heat dissipation area.

[0022] like Figure 4As shown, a support frame 65 is fixedly connected to the top of the inner surface of the connecting frame 61, an electric motor 66 is fixedly connected to the middle of the support frame 65, a rotating shaft 67 is fixedly connected to the output shaft of the electric motor 66, and a guide fan 68 is fixedly connected to the top of the outer surface of the rotating shaft 67. Here, the support frame 65 stably supports the electric motor 66, and the electric motor 66 drives the guide fan 68 to rotate, accelerating the airflow inside the connecting frame 61 and quickly removing the heat emitted by the heat dissipation fins 64.

[0023] like Figure 4 As shown, the bottom end of the rotating shaft 67 passes through the metal heat pipe 63 and several guide fans 69 are fixedly connected to its outer surface. The guide fans 69 are rotatably connected inside the metal heat pipe 63. Here, the guide fans 69 rotate with the rotating shaft 67 to push the coolant to circulate inside the metal heat pipe 63, thereby enhancing the heat exchange efficiency between the coolant and the pipe wall and ensuring uniform cooling of the fixed template 1.

[0024] The usage method and working principle of this device are as follows: When using it, first select the mold cavity module 5 with the corresponding wall thickness. Align the positioning slide groove 55 of the plug-in post 51 with the positioning slide bar 13 of the plug-in groove 11 and push it in. After the threaded rod 12 passes through the groove 53, tighten the threaded cap 54 to fix it, ensuring that the mold cavity body 52 and the sprue sleeve are connected. The device is activated, the moving template 2 moves to the left so that the mold core 4 is inserted into the mold cavity body 52 to form a cavity, and the injection tube 3 injects the molten material into the cavity through the sprue sleeve. Simultaneously, the electric motor 66 is started, and the rotating shaft 67 drives the guide fan 69 and guide fan 68 to rotate. The guide fan 69 drives the coolant in the metal heat pipe 63 to circulate, absorbing the heat of the fixed platen 1 and the mold cavity module 5. The heat is transferred to the heat dissipation fins 64 through the metal heat pipe 63. The guide fan 68 promotes air convection in the connecting frame 61. Outside air enters through the dustproof net 62, takes away the heat of the heat dissipation fins 64, and is then discharged from the dustproof net 62 above. After the raw material cools and solidifies, the moving template 2 moves to the right, the mold core 4 is pulled out, and the preform is taken out through the ejection mechanism; When a lighter preform needs to be produced, unscrew the threaded cap 54, remove the old mold cavity module 5, replace it with a new module with a smaller wall thickness, and fix it in place.
