Technical Field

[0001] This utility model relates to the field of plastic molding technology, and in particular to a heat-stabilized modified plastic molding device. Background Technology

[0002] Heat-stabilized modified plastic molding equipment plays a crucial role in the plastics processing industry, widely used in the production of various plastic products requiring high thermal stability, such as automotive parts and electronic device housings. It processes heat-stabilized modified plastic raw materials into molds to meet the stringent performance requirements of different industries. Current equipment typically requires the following technologies in practical applications:

[0003] 1. Reliable mold fixing technology ensures that the mold remains stable and does not shift during the injection molding process;

[0004] 2. Precise mold positioning technology ensures accurate mold closing between the moving mold and the stationary mold, improving the precision of the molded products;

[0005] 3. Convenient mold changing technology, enabling quick mold replacement to adapt to the production of different products;

[0006] 4. Safe electromagnetic control technology effectively controls and monitors the magnetic force of the magnetic panel, ensuring operational safety;

[0007] 5. Stable injection molding technology ensures that heat-stable modified plastics are molded under suitable conditions, thus ensuring product quality.

[0008] Currently, various molding devices are used to mold heat-stabilized modified plastics. Some devices use simple bolt connections to fix the mold, while others use magnetic panels to fix the mold.

[0009] However, the above method has a prominent hardware structure problem: the existing device lacks the function of guiding irregular positioning blocks. When installing the mold, the mold is fixed by simple connection or magnetic attraction, lacking effective positioning guidance, making it difficult to achieve fast and accurate positioning. This not only increases the installation difficulty and time cost, but also affects the efficiency of mold replacement. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a heat-stabilized modified plastic molding device, which solves the technical problem that existing devices lack the guiding function of irregularly shaped positioning blocks. When installing molds, the molds rely solely on simple connections or magnetic fixation, lacking effective positioning guidance, making it difficult to achieve rapid and accurate positioning. This not only increases the installation difficulty and time cost but also affects the efficiency of mold replacement.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A heat-stabilized modified plastic molding apparatus includes a magnetic panel. Two L-shaped positioning blocks are fixedly connected to the outer surface of the magnetic panel. Two rectangular positioning blocks are fixedly connected to one end of the outer surface of the magnetic panel near the two L-shaped positioning blocks. The two rectangular positioning blocks are located at the upper ends of the two L-shaped positioning blocks. A stationary mold is provided on the outer surface of the magnetic panel. The two L-shaped positioning blocks and the two rectangular positioning blocks are located on the outer surface of the stationary mold. Two lifting rings are fixedly connected to the upper end of the stationary mold. A sliding frame is slidably connected to the outer surface of the magnetic panel. An abutment plate is slidably connected to the outer surface of the sliding frame. The abutment plate is in contact with the outer surface of the stationary mold.

[0013] Preferably, the outer surface of the sliding frame is threaded with a clamping bolt, and the clamping bolt is in contact with the outer surface of the sliding frame.

[0014] Preferably, a T-shaped slider is fixedly connected to the end of the outer surface of the sliding frame away from the contact plate, and a T-shaped groove is provided inside the magnetic panel.

[0015] Preferably, the T-shaped slider is slidably connected to the outer surface of the T-shaped groove, and the injection molding machine body is fixedly connected to the outer surface of the magnetic panel.

[0016] Preferably, a moving mold is slidably connected inside the injection molding machine body, and four positioning rods are fixedly connected to the outer surface of the moving mold.

[0017] Preferably, the magnetic panel has four cylindrical slots inside, and the four positioning rods are all on the same horizontal line as the four cylindrical slots.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The rectangular and L-shaped positioning blocks on the magnetic panel serve to assist in positioning the stationary mold. The upper end of the rectangular positioning block has an inclined surface towards the center of the stationary mold. When the stationary mold is lowered, it first contacts this surface for guidance, ensuring stable alignment during installation. The lower L-shaped positioning block is similar to a right triangle with an L-shaped groove inside. When the lower end of the stationary mold is tilted, it first contacts the inclined surface and slides into the groove for positioning. These four irregularly shaped positioning blocks make the installation of the stationary mold more accurate and smooth, helping workers to quickly find the correct position and complete the installation efficiently.

[0020] 2. After the static mold is positioned, the magnetic panel generates a magnetic field by energizing the internal electromagnetic coil. The surrounding iron core further enhances the magnetic field strength. The static mold is mostly made of ferromagnetic metal, which is magnetized when it approaches the magnetic panel. It attracts the magnetic field of the panel and generates an adsorption force to fix the static mold. The adsorption force can be adjusted by controlling the current. It is equipped with a power failure protection device, a magnetic force detection sensor and other safety mechanisms to ensure that the static mold is easy to install and disassemble and that the production process is safe. At this time, the sliding frame is reset, and the tightening bolts are tightened so that the contact plate is pressed against the surface of the static mold to complete the installation and fixation of the static mold, providing a more stable installation and fixation effect for the static mold.

[0027] This application provides a heat-stabilized modified plastic molding apparatus that effectively solves the problem of existing devices lacking the guiding function of irregularly shaped positioning blocks. During mold installation, the mold relies solely on simple connections or magnetic fixation, lacking effective positioning guidance, making rapid and accurate positioning difficult. This not only increases installation difficulty and time costs but also affects mold replacement efficiency. The rectangular and L-shaped positioning blocks on the magnetic panel assist in positioning the stationary mold. The upper end of the rectangular positioning block has an inclined surface towards the center of the stationary mold. When the stationary mold is lowered, it first contacts this surface for guidance, ensuring stable installation alignment. The lower L-shaped positioning block resembles a right-angled triangle with an L-shaped groove inside. When the lower end of the stationary mold is tilted, it first contacts the inclined surface and slides into the groove for positioning. These four irregularly shaped positioning blocks make the installation of the stationary mold more accurate and smooth, helping workers quickly find the correct position and complete the installation efficiently.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that existing devices lack the guiding function of irregularly shaped positioning blocks. When installing molds, the molds rely solely on simple connections or magnetic fixation, lacking effective positioning guidance, making it difficult to achieve rapid and accurate positioning. This not only increases installation difficulty and time costs but also affects mold replacement efficiency. The overall concept is as follows: A heat-stabilized modified plastic molding device includes a magnetic panel 11. Two L-shaped positioning blocks 12 are fixedly connected to the outer surface of the magnetic panel 11. Two rectangular positioning blocks 13 are fixedly connected to one end of the outer surface of the magnetic panel 11 near the two L-shaped positioning blocks 12. Both rectangular positioning blocks 13 are located at the upper ends of the two L-shaped positioning blocks 12. A stationary mold 14 is provided on the outer surface of the magnetic panel 11. One L-shaped positioning block 12 and two rectangular positioning blocks 13 are located on the outer surface of the stationary mold 14. Two lifting rings 15 are fixedly connected to the upper end of the stationary mold 14. A sliding frame 16 is slidably connected to the outer surface of the magnetic panel 11, and an abutment plate 17 is slidably connected to the outer surface of the sliding frame 16. The abutment plate 17 is in contact with the outer surface of the stationary mold 14. A locking bolt 18 is threadedly connected to the outer surface of the sliding frame 16, and the locking bolt 18 is in contact with the outer surface of the sliding frame 16. When the stationary mold 14 needs to be disassembled and replaced after a batch of materials has been processed, the locking bolt 18 is turned off to loosen the contact with the abutment plate 17. At this time, the sliding frame 16 is pulled outward to slide, thereby releasing the limit on the stationary mold 14. Then, the lifting rings 15 are lifted upward by the lifting equipment for disassembly, and a new stationary mold is installed. At 14:00, the static mold 14 is hoisted to a position close to the surface of the magnetic panel 11 by connecting it to the hoisting equipment and hoisting ring 15. At this time, the rectangular positioning blocks 13 and L-shaped positioning blocks 12 installed on the surface of the magnetic panel 11 provide auxiliary positioning during installation. The two rectangular positioning blocks 13 are shaped like rectangular blocks, each with an inclined surface at its upper end, facing the center of the static mold 14. When placing the static mold 14 from top to bottom, it will first contact the upper surfaces of the two rectangular positioning blocks 13. The two inclined surfaces provide accurate guidance, ensuring stable alignment of the static mold 14. At the lower end of the static mold 14's installation position, two L-shaped positioning blocks 12 are installed. Shaped like a right triangle, the L-shaped groove inside the stationary mold 14 is designed to fit against its surface. When the stationary mold 14 is placed from top to bottom, if its lower end is tilted, it will first fit against the tilted surfaces of the two L-shaped positioning blocks 12 and slide downwards along these tilted surfaces to be positioned within the L-shaped groove. By setting a total of four irregularly shaped L-shaped positioning blocks 12 and rectangular positioning blocks 13, a more accurate and smooth positioning effect is provided for the installation of the stationary mold 14, which helps the workers quickly find the accurate installation position of the stationary mold 14, thus achieving rapid and efficient installation. The outer surfaces of the two L-shaped positioning blocks 12 and the two rectangular positioning blocks 13 are all tilted by beveling right angles. When installing the stationary mold 14 from the outside in...The two L-shaped positioning blocks 12 and the two rectangular positioning blocks 13 can still serve a positioning and guiding function.

[0030] A T-shaped slider 19 is fixedly connected to the end of the outer surface of the sliding frame 16 away from the contact plate 17. A T-shaped groove 21 is opened inside the magnetic panel 11. The T-shaped slider 19 is slidably connected to the outer surface of the T-shaped groove 21. After the stationary mold 14 is positioned, the magnetic panel 11 generates a magnetic field by energizing the internal electromagnetic coil. The surrounding iron core further enhances the magnetic field strength. The stationary mold 14 is mostly made of ferromagnetic metal. When it is close to the magnetic panel 11, it is magnetized and attracts the magnetic field of the panel to generate an adsorption force, thereby fixing the stationary mold 14. The adsorption force can be adjusted by controlling the current. It is equipped with a power failure protection device, a magnetic force detection sensor and other safety mechanisms to ensure that the stationary mold 14 is easy to install and disassemble and safe in the production process. At this time, the sliding frame 16 is reset, and the abutment bolt 18 is tightened to make the contact plate 17 press against the surface of the stationary mold 14 to complete the installation and fixing of the stationary mold 14. The T-shaped groove 21 will limit the sliding trajectory of the T-shaped slider 19 and provide a smoother sliding effect.

[0031] The outer surface of the magnetic panel 11 is fixedly connected to the injection molding machine body 22. A moving mold 23 is slidably connected inside the injection molding machine body 22. Four positioning rods 24 are fixedly connected to the outer surface of the moving mold 23. Four cylindrical slots 25 are provided inside the magnetic panel 11. The four positioning rods 24 and the four cylindrical slots 25 are all on the same horizontal line. The moving mold 23 is pushed to slide by a power element inside the injection molding machine body 22. Smooth cylindrical rods installed on the surface of the magnetic panel 11 limit the sliding trajectory of the moving mold 23. The moving mold 23 slides and engages with the stationary mold 14 to complete mold closing. At this time, the injection molding machine body 22 injects plastic material into the stationary mold 14. The mold closing of the moving mold 23 and the stationary mold 14 completes the process. In the extrusion molding operation, given the requirements of heat-stabilized modified plastics for molding conditions, the injection molding machine body 22 will inject plastic material in its optimal molten state with uniform temperature and pressure into the mold cavity of the stationary mold 14 through a high-speed and precise injection system, according to injection parameters specifically formulated for heat-stabilized modified plastics. This aims to ensure that the heat-stabilized modified plastic can quickly and uniformly fill the material in the cavity and form an ideal microstructure during the subsequent holding pressure and cooling process, thereby fully utilizing its excellent thermal stability performance. When the moving mold 23 and the stationary mold 14 are fitted together, the positioning pin 24 installed on the surface of the moving mold 23 will be inserted into the cylindrical slot 25, thereby providing a more accurate guiding function.

[0032] To address the problems existing in the prior art, this utility model provides a heat-stabilized modified plastic molding device. The rectangular positioning block 13 and the L-shaped positioning block 12 on the magnetic panel 11 assist in positioning the stationary mold 14. The upper end of the rectangular positioning block 13 has an inclined surface towards the center of the stationary mold 14. When the stationary mold 14 is lowered, it first contacts this surface for guidance, ensuring stable installation and alignment. The lower end of the L-shaped positioning block 12 resembles a right triangle and has an L-shaped groove inside. When the lower end of the stationary mold 14 is tilted, it first contacts the inclined surface and slides into the groove for positioning. These four irregularly shaped positioning blocks make the installation of the stationary mold 14 more accurate and smooth, helping workers quickly find the correct position and complete the installation efficiently.

[0033] Working principle:

[0034] In the first step, the moving mold 23 is pushed to slide by the power element inside the injection molding machine body 22. The smooth round rod installed on the surface of the magnetic panel 11 limits the sliding trajectory of the moving mold 23. The moving mold 23 slides and fits with the stationary mold 14 to complete the mold closing. At this time, the injection molding machine body 22 injects plastic material into the stationary mold 14. The extrusion molding operation is realized by the mold closing of the moving mold 23 and the stationary mold 14. Considering the requirements of heat-stabilized modified plastics for molding conditions, the injection molding machine body 22 will inject the plastic material in the optimal melting state and with uniform temperature and pressure into the mold cavity of the stationary mold 14 through a high-speed and precise injection system according to the injection parameters specifically formulated for heat-stabilized modified plastics. This is to ensure that the heat-stabilized modified plastic can quickly and evenly fill the material in the cavity and form an ideal microstructure in the subsequent holding pressure and cooling process, thereby giving full play to its excellent thermal stability performance. When the moving mold 23 and the stationary mold 14 fit together, the positioning pin 24 installed on the surface of the moving mold 23 will be inserted into the cylindrical slot 25 to provide a more accurate guiding function.

[0035] The second step involves disassembling and replacing the stationary mold 14 after the processing of a single batch of materials. Tightening the clamping bolt 18 releases the contact with the abutment plate 17. At this point, pulling the sliding frame 16 outwards releases the limit on the stationary mold 14. The lifting ring 15 is then lifted upwards for disassembly using a lifting device. When installing the new stationary mold 14, the lifting device is connected to the lifting ring 15, lifting the stationary mold 14 close to the surface of the magnetic panel 11. The rectangular positioning blocks 13 and L-shaped positioning blocks 12 installed on the surface of the magnetic panel 11 then play an auxiliary positioning role during installation. The two rectangular positioning blocks 13 are similar in shape to rectangular blocks. Two rectangular positioning blocks 13 each have an inclined surface at their upper ends, both facing the center of the stationary mold 14. When the stationary mold 14 is placed from top to bottom, it will first come into contact with the upper surfaces of the two rectangular positioning blocks 13. At this time, the two inclined surfaces will provide accurate guidance, ensuring the stable alignment of the stationary mold 14. At the lower end of the stationary mold 14, two L-shaped positioning blocks 12 are installed. The two L-shaped positioning blocks 12 are similar in shape to right-angled triangles, and L-shaped grooves are opened inside them to fit with the surface of the stationary mold 14. When the stationary mold 14 is placed from top to bottom, if there is any tilt at its lower end, it will first come into contact with the two L-shaped positioning blocks 13. The inclined surface of the positioning block 12 fits and slides downward along its inclined surface to be positioned in the L-shaped groove. By setting a total of four irregularly shaped L-shaped positioning blocks 12 and rectangular positioning blocks 13, a more accurate and smooth positioning effect is provided for the installation of the stationary mold 14, which helps the staff to quickly find the accurate installation position of the stationary mold 14, thereby realizing the installation of the stationary mold 14 quickly and efficiently. The outer end surfaces of the two L-shaped positioning blocks 12 and the two rectangular positioning blocks 13 are all inclined surfaces formed by chamfering right angles. When installing the stationary mold 14 from the outside to the inside, the two L-shaped positioning blocks 12 and the two rectangular positioning blocks 13 can still play a positioning guide role. After the stationary mold 14 is positioned, the magnetic panel 11 generates a magnetic field by energizing its internal electromagnetic coil. The surrounding iron core further enhances the magnetic field strength. The stationary mold 14 is mostly made of ferromagnetic metal. When it approaches the magnetic panel 11, it is magnetized and attracts the magnetic field of the panel to generate an adsorption force, thereby fixing the stationary mold 14. The adsorption force can be adjusted by controlling the current. It is equipped with a power failure protection device, a magnetic force detection sensor and other safety mechanisms to ensure that the stationary mold 14 is easy to install and disassemble and that the production process is safe. At this time, the sliding frame 16 is reset, and the tightening bolt 18 is then tightened so that the contact plate 17 presses against the surface of the stationary mold 14 to complete the installation and fixing of the stationary mold 14.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
