Technical Field

[0001] This utility model relates to a foaming molding device for a microporous structure on the surface of a filler masterbatch, and particularly to a foaming molding device for a microporous structure on the surface of a filler masterbatch applied in the field of foaming molding equipment. Background Technology

[0002] The microporous structure foaming molding equipment for filled masterbatch is a specialized device used to generate uniform microporous structures on the surface of polymer masterbatch. Combining supercritical fluid foaming technology with precision molding processes, it achieves material lightweighting and functionalization by controlling gas diffusion, nucleation, and shaping processes. Its core modules include a supercritical fluid injection system, a pressure gradient control unit, and an intelligent temperature-controlled mold.

[0003] The core function of the microporous structure foaming molding equipment for filler masterbatch is: customized microporous structure (utilizing supercritical CO2 / N2 to form a single-phase sol in the molten masterbatch, inducing micropore nucleation through pressure gradient release, generating uniform surface pores with a pore size of 10-50μm, improving the material's adsorption, sound insulation, and heat insulation performance; combined with biomimetic layered structure design, such as a hard shell-porous core, it can simultaneously enhance surface hardness and core weight reduction, suitable for lightweight automotive components and other fields), and efficient and environmentally friendly production (physical foaming technology replaces chemical foaming agents, reducing VOCs). Cs emissions; built-in waste gas recovery system can recycle more than 90% of unreacted gases, reducing raw material costs; fully automatic parameter control, temperature ±1℃, pressure ±0.1MPa, improving yield to 98%; supports rapid switching of multiple material formulas, increasing production efficiency by 30%) and functional material expansion (can produce lightweight materials such as EPE foam masterbatch, with impact resistance and corrosion resistance, widely used in electronic packaging, building insulation and other fields; through the nano-coating technology on the mold surface, the bubble distribution is directionally controlled to achieve high-density surface micropores, porosity >80%, reducing the need for post-processing). Its main applications are: packaging industry (manufacturing high-cushioning EPE foam to protect precision electronic components), automotive manufacturing (microporous foam core material for lightweight interior parts), and construction field (producing thermal insulation and sound insulation boards, such as polyurethane composite wall panels).

[0004] The existing foaming molding equipment for microporous structures on the surface of filler masterbatch is difficult to clean after use, and it also increases the workload of personnel, thus causing great inconvenience to personnel when cleaning the foaming molding equipment for microporous structures on the surface of filler masterbatch. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the existing foaming molding equipment for microporous structures on the surface of the filler masterbatch is not only difficult to clean after use, but also increases the workload of personnel.

[0006] To solve the above problems, this utility model provides a foaming molding device for microporous structures on the surface of a filling masterbatch, including a molding equipment body. A sealing cover is fixedly connected to the upper end of the molding equipment body by bolts. An electric push rod is fixedly connected to the lower end of the sealing cover. A connecting box is fixedly connected to the telescopic end of the electric push rod. An air pump is fixedly connected inside the connecting box. A connecting pipe is fixedly connected to the air outlet end of the air pump. Multiple air inlet pipes are fixedly connected to the outer end of the connecting pipe. The ends of the multiple air inlet pipes that are far apart from each other are fixedly connected to the same inflation plate. An inflation ring is fixedly connected to the outer end of the inflation plate.

[0007] In the above-mentioned foaming molding device for microporous structures on the surface of the filler masterbatch, it is easy for personnel to clean its interior, and the cleaning steps are simple, which greatly reduces the cleaning workload of personnel.

[0008] As a further improvement of this application, after the air ring is inflated, its outer end fits tightly against the inner wall of the molding equipment body.

[0009] As a further improvement to this application, the end of the connecting pipe away from the air pump has a closed structure.

[0010] As a further improvement of this application, multiple nozzles are fixedly connected to the outer end of the connecting box, and multiple water inlet pipes are fixedly connected to the upper end of the connecting box.

[0011] As a further improvement of this application, the lower end of the water inlet pipe is inserted into the inside of the connector box and communicates with the side end of the nozzle, while the upper end of the water inlet pipe movably passes through the sealing cover and extends out of it to the outside.

[0012] As a further improvement of this application, an exhaust pipe is fixedly connected to the side end of the molding equipment body, and a switch valve is fixedly connected to the upper end of the exhaust pipe.

[0013] As another improvement of this application, the outer end of the exhaust pipe is threaded with a sleeve, the inner wall of the sleeve is coated with an activated carbon layer, and a filter plate is fixedly connected inside the sleeve.

[0014] In summary, before cleaning the inner wall of the molding equipment, the air pump can be started, allowing gas to be injected into the inflation plate and inflation ring through the connecting pipe and air inlet pipe. This causes the inflation plate and inflation ring to expand until the outer end of the inflation ring abuts against the inner wall of the molding equipment. An external water pump is then used to inject water into the water inlet pipe and nozzle, causing water to spray onto the inner wall of the molding equipment. Afterward, the electric push rod is activated, its telescopic end pushing the connecting box and all its mechanisms downwards within the molding equipment, thus using the inflation ring to clean the inner wall of the molding equipment. The adhering material is scraped off. At the same time, the position of the nozzle inside the molding equipment is changed so that water can be sprayed at different locations inside the molding equipment. Then, the connecting box is moved up and down repeatedly, and the air ring is used to repeatedly scrape off the inner wall of the molding equipment. The scraped material is then rinsed off. Finally, the scraped material will flow with the water to the inner bottom wall of the molding equipment. The mixture of material and water can then be removed from the bottom of the molding equipment. This application makes it easy for personnel to clean the inside of the equipment, and the cleaning steps are simple, greatly reducing the cleaning workload of personnel. Attached Figure Description

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figure 1-5 A foaming molding device for microporous structures on the surface of a filling masterbatch is shown. It includes a molding equipment body 1. A sealing cover 2 is fixedly connected to the upper end of the molding equipment body 1 by bolts. An electric push rod 3 (model XX-L) is fixedly connected to the lower end of the sealing cover 2. A connecting box 4 is fixedly connected to the telescopic end of the electric push rod 3. An air pump 5 is fixedly connected inside the connecting box 4. A connecting pipe 6 is fixedly connected to the air outlet end of the air pump 5. Multiple air inlet pipes 7 are fixedly connected to the outer end of the connecting pipe 6. The ends of the multiple air inlet pipes 7 that are far apart from each other are fixedly connected to the same inflation plate 8. An inflation ring 9 is fixedly connected to the outer end of the inflation plate 8.

[0025] After the air ring 9 is inflated, its outer end fits tightly against the inner wall of the molding equipment body 1. The end of the connecting pipe 6 away from the air pump 5 is a closed structure. Multiple nozzles 10 are fixedly connected to the outer end of the connecting box 4. Multiple water inlet pipes 11 are fixedly connected to the upper end of the connecting box 4.

[0026] The lower end of the water inlet pipe 11 is inserted into the inside of the connecting box 4 and communicates with the side end of the nozzle 10. The upper end of the water inlet pipe 11 movably passes through the sealing cover 2 and extends out of it to the outside. The side end of the molding equipment body 1 is fixedly connected to the exhaust pipe 12, and the upper end of the exhaust pipe 12 is fixedly connected to the switch valve 13.

[0027] The use of this application involves the following steps:

[0028] Step 1: Before cleaning the inner wall of the molding equipment body 1, the air pump 5 can be started so that the air outlet injects gas into the air plate 8 and the air ring 9 through the connecting pipe 6 and the air inlet pipe 7, thereby causing the air plate 8 and the air ring 9 to expand until the outer end of the air ring 9 abuts against the inner wall of the molding equipment body 1.

[0029] Step 2: Use an external water pump to inject water into the water inlet pipe 11 and the nozzle 10, so that the water is sprayed out from the nozzle 10 and sprayed onto the inner wall of the molding equipment body 1. Then, start the electric push rod 3, so that its telescopic end pushes the connecting box 4 and all its mechanisms to move downwards inside the molding equipment body 1. This allows the air ring 9 to scrape off the material adhering to the inner wall of the molding equipment body 1. At the same time, change the position of the nozzle 10 inside the molding equipment body 1 so that the water is sprayed at different locations inside the molding equipment body 1.

[0030] Then, the connecting box 4 is moved up and down repeatedly, and the air ring 9 is used to repeatedly scrape the inner wall of the molding equipment body 1. The scraped material is then rinsed. Finally, the scraped material will flow with the water to the inner bottom wall of the molding equipment body 1. Then, the mixture of material and water can be taken out from the bottom of the molding equipment body 1.

[0031] In summary, this application facilitates internal cleaning by personnel, and the cleaning process is simple, greatly reducing the workload of personnel.

[0032] Second implementation method:

[0033] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0034] Figure 2 The exhaust pipe 12 is shown to be threaded with a sleeve 14 at its outer end. The inner wall of the sleeve 14 is coated with an activated carbon layer 15, and a filter plate 16 is fixedly connected inside the sleeve 14.

[0035] When the switch valve 13 is opened and exhaust is carried out through the exhaust pipe 12, the activated carbon layer 15 performs the initial adsorption and purification treatment on the gas. After that, the gas will pass through the filter plate 16 and drift to the outside of the sleeve pipe 14. The filter plate 16 can filter and purify the gas, further improving the cleanliness of the gas and making it less likely to pollute the environment.

[0036] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
