Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner filter molds, and particularly relates to an injection mold for filters. Background Art

[0002] An air conditioner filter is a component used in an air conditioner system. Its main functions are to filter and purify air, capture tiny particles such as dust, pollen, bacteria, etc., protect the air conditioner equipment, improve air quality, and enhance the efficiency of the air conditioner. Common types include ordinary filters, HEPA filters, activated carbon filters, and electrostatic filters, which need to be cleaned or replaced regularly to ensure their effectiveness.

[0003] The existing patent CN212472251U discloses that an upper mold is arranged at the upper end of the lower mold, the lower connecting plate and the upper connecting plate are connected to each other through a locking screw, a ejector rod is fixedly connected to the upper end of the lower connecting plate, flow channels are arranged inside both the lower mold and the upper mold, an air inlet is arranged on one side of the flow channel inside the lower mold and the upper mold, an air outlet is arranged on the other side of the flow channel inside the lower mold and the upper mold, a rubber plug is arranged inside the air outlet, cooling fans are fixedly connected to the other two sides of the lower mold and the upper mold, and one end of a first connecting pipe is fixedly connected to one side of the cooling fan.

[0004] This patent aims to solve the problem of extremely low cooling speed when cooling the mold by the static cooling method. By accelerating the air flow in the flow channel through the cooling fan, the heat in the injection molded product can be quickly exported, realizing the rapid heat dissipation of the mold, and thus improving the production efficiency of the mold.

[0005] However, in actual use, there are still the following deficiencies. For example, when a plastic injection molded part experiences uneven cooling during the manufacturing process, this unevenness will cause different parts of the injection molded part to shrink at different rates. This differential shrinkage rate will generate uneven stress inside the injection molded part. If it cannot be effectively released, it may cause deformation of the injection molded part during the cooling process. This deformation will not only affect the appearance of the injection molded part, making its shape distorted, but may also cause the dimensional accuracy of the injection molded part not to meet the pre-designed requirements.

[0006] Therefore, the utility model provides an injection mold for filters. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide an injection mold for filters.

[0008] To achieve the above purpose, the utility model adopts the following technical scheme: an injection mold for filters, including an injection component and an injection molded part, and a cooling component is fixedly connected inside the injection component;

[0009] The cooling component includes a cold air duct and a cold air chamber. One end of the cold air duct is fixedly connected to a dispersion pipe.

One end of the connecting pipe away from the partition is fixedly connected to a cooling block. An air outlet pipe is fixedly connected to the outer side of the cooling block.

[0010] As a preferred embodiment, the injection molding component includes an outer frame. One end of the outer frame is fixedly connected to an inner frame. A template is fixedly connected to the inside of the inner frame. An injection port is fixedly connected to the top of the inner frame.

[0013] The technical effect of adopting the above technical solution is: It can effectively manage and guide the air flow. Such a design helps to more effectively distribute the cold air and improve the cooling efficiency.

[0014] As a preferred embodiment, the outer side of the cooling block is fixedly connected to the inside of the template, and the outer side of the injection molded part is clamped on the template.

[0015] The technical effect of adopting the above technical solution is: It enables the cold air to be accurately transmitted to the injection molded part.

[0016] As a preferred embodiment, the outer side of the cold air duct is fixedly connected to the outer frame and extends outward to be connected to a cold air device.

The partition plate guides the flow of cold air and fixes the position of the dispersion pipe, increasing the surface area of contact between the cold air and the mold. The cold air connecting pipe transmits cold air to the cooling block to improve the cooling efficiency and ensure that the mold maintains an appropriate temperature during operation. Finally, the electric valve is opened, and the cold air is quickly discharged through the air outlet pipe to prevent the cold air from staying inside the mold. Such a design effectively ensures that the cold air can be evenly distributed to various parts of the mold, increases the contact area between the cold air and the mold, enables the mold to reach the required low temperature faster, shortens the cooling time, and effectively prevents the deformation of the injection molded part caused by uneven cooling.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Such as Figure 1 - Figure 4As shown in the figure, this embodiment provides a technical solution: a filter screen injection mold, including an injection component 1 and an injection part 3, and a cooling component 2 is fixedly connected inside the injection component 1;

[0032] The cooling component 2 includes a cold air duct 21 and a cold air cavity 26. The outer side of the cold air duct 21 is fixedly connected to the outer frame 11 and extends outward to be connected to a cold air device. One end of the cold air duct 21 is fixedly connected to a dispersion pipe 22. The outer side of the dispersion pipe 22 is fixedly connected to a partition plate 23. The outer side of the partition plate 23 is fixedly connected to the inside of the inner frame 12. One end of the dispersion pipe 22 away from the cold air duct 21 is fixedly connected to a connecting pipe 24. One end of the connecting pipe 24 away from the partition plate 23 is fixedly connected to a cooling block 25. The outer side of the cooling block 25 is fixedly connected to the inside of the template 13. The outer side of the cooling block 25 is fixedly connected to an air outlet pipe 27. The outer side of the air outlet pipe 27 is fixedly connected to the inner frame 12. The outer side of the cold air duct 21 is fixedly connected to the outer frame 11 and extends outward to be connected to a cold air device. The cold air provided by the cold air device enters the cold air duct 21 to ensure a stable cold air source for the cooling system. One end of the cold air duct 21 is fixedly connected to a dispersion pipe 22. The design of the dispersion pipe 22 enables the cold air to be evenly distributed to various parts of the injection mold to ensure consistent cooling effect. The outer side of the dispersion pipe 22 is fixedly connected to a partition plate 23. The existence of the partition plate 23 helps to guide the flow of cold air and also fixes the position of the dispersion pipe 22 to enhance the structural stability. The outer side of the partition plate 23 is fixedly connected to the inside of the inner frame 12. This fixing method ensures the overall structure of the cooling component 2 and the injection mold is compact and prevents the cooling component 2 from shifting during operation. One end of the dispersion pipe 22 away from the cold air duct 21 is fixedly connected to a connecting pipe 24. As a channel for cold air transmission, the connecting pipe 24 further transmits the cold air to the key parts of the mold. One end of the connecting pipe 24 away from the partition plate 23 is fixedly connected to a cooling block 25. The design of the cooling block 25 increases the surface area of contact between the cold air and the mold, improves the cooling efficiency, and ensures that the mold maintains an appropriate temperature during operation. The outer side of the cooling block 25 is fixedly connected to the inside of the template 13. This design ensures that the cold air can directly act on the injection part, improves the cooling effect, and prevents deformation and defects of the injection part 3. The design of the air outlet pipe 27 enables the cold air to be quickly discharged after passing through the cooling block 25, preventing the cold air from staying inside the mold, and an electric valve is provided on the air outlet pipe 27 to avoid gas outflow.

[0033] Furthermore, as Figure 2 - Figure 3As shown in the figure: The injection molding assembly 1 includes an outer frame 11. One end of the outer frame 11 is fixedly connected to an inner frame 12. Inside the inner frame 12, a template 13 is fixedly connected. The outer side of the injection molded part 3 is snap-fitted onto the template 13. A cold air cavity 26 is opened between the inner frame 12 and the partition plate 23. The top end of the inner frame 12 is fixedly connected to an injection port 14. The injection molding assembly 1 includes an outer frame 11. The outer frame 11 serves as the support structure of the entire injection molding device, providing a solid foundation. The outer frame 11 is closely combined with the inner frame 12, further enhancing the overall rigidity and stability. Inside the inner frame 12, a template 13 is fixedly connected. The template 13 serves as the fixed base of the injection molded part 3, ensuring that the injection molded part 3 maintains the correct position and shape during the injection molding process, thus guaranteeing the consistency and precision of the finished product. The outer side of the injection molded part 3 is snap-fitted onto the template 13. This design ensures that the injection molded part 3 does not shift or fall off during the injection molding and cooling processes, improving the safety of the operation and the quality of the finished product. The cold air cavity 26 is opened between the inner frame 12 and the partition plate 23. This design utilizes the space between the inner frame 12 and the partition plate 23 to form an independent cooling area, enabling cold air to effectively circulate and cool the injection molded part 3, enhancing the cooling efficiency. The injection port 14 is the channel for the injection molding material to enter the mold, ensuring that the molten material can be accurately and quickly injected into the mold.

[0034] Working principle:

[0035] As Figure 1 - Figure 4 shown:

[0036] In use: First, the outer frame 11 and the inner frame 12 of the injection molding component 1 are tightly combined, enhancing the overall rigidity and stability. Subsequently, a template 13 is fixedly connected inside the inner frame 12. The template 13 serves as the fixed base for the injection molded part 3, ensuring that the injection molded part 3 maintains the correct position and shape during the injection molding process, thereby ensuring the consistency and precision of the finished product. The outer side of the injection molded part 3 is snap-fitted onto the template 13 to ensure that it does not shift or fall off during the injection molding and cooling processes, improving the safety of the operation and the quality of the finished product. Then, the outer side of the cold air duct 21 of the cooling component 2 is fixedly connected to the outer frame 11 and extends outward to be connected to the cold air blower. The cold air provided by the cold air blower enters the system through the cold air duct 21 and can be evenly distributed to all parts of the injection mold through the dispersion pipe 22 to ensure consistent cooling effect. At this time, the partition plate 23 guides the flow of the cold air and fixes the position of the dispersion pipe 22, enhancing the structural stability. The cold air connecting pipe 24 of the dispersion pipe 22 serves as the channel for cold air transmission. Subsequently, when reaching the cooling block 25, the surface area of contact between the cold air and the mold is increased, improving the cooling efficiency and ensuring that the mold maintains an appropriate temperature during operation, ensuring that the low temperature can be transmitted to the inside of the template 13. This design ensures that the cold air can directly act on the injection molding part, improving the cooling effect and preventing deformation and defects of the injection molded part 3. Finally, the electric valve is opened to ensure that the cold air can be quickly discharged through the air outlet pipe 27 after passing through the cooling block 25, preventing the cold air from staying inside the mold.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
