Description

Technical Field

[0001] This utility model relates to the field of fabric processing, and more specifically, to a mold for forming breathable holes in an antistatic and breathable sofa fabric. Background Technology

[0002] There are two main methods for creating ventilation holes in existing fabric sofa upholstery: 1. **Woven ventilation holes:** During the fabric weaving process, ventilation holes are formed through a special weaving technique. For example, using an "S"-shaped weaving method, the upper and lower weaving threads form diamond-shaped holes, through which the connecting threads of the upper and lower weaving layers pass, thus creating ventilation holes. 2. **Mold-formed ventilation holes:** During fabric production, ventilation holes are formed on the fabric using a mold. Mold-formed ventilation holes are simpler, more efficient, and widely used.

[0003] Existing perforation forming molds include an upper mold, a lower mold, and protrusions and recesses that work together to punch holes in the fabric. However, after punching the fabric, some fabric remains on the mold, requiring manual cleaning after each processing. This is not only troublesome but also quite dangerous. To address these issues, a solution is proposed below. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a mold for forming breathable holes in antistatic and breathable sofa fabric, which allows for easy cleaning of the mold.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A permeable hole forming mold for an antistatic and breathable sofa fabric includes an upper mold and a lower mold. The upper mold is located above the lower mold and the upper mold and the lower mold are adapted to each other. A positioning component is provided between the upper mold and the lower mold. A plurality of push rods are evenly provided at the bottom of the upper mold. A plurality of recesses are evenly provided at the top of the lower mold. The recesses and push rods correspond to and are adapted to each other. An air channel is provided at one end of the push rod. An air blowing component for supplying air to the air channel is provided inside the upper mold. A cleaning component for cleaning the surface of the upper mold is provided at the bottom of the upper mold.

[0007] Preferably, the air blowing assembly includes a flow divider box and a valve. The flow divider box is installed on the upper mold and has several air ports. The air ports correspond to air passages. An air inlet is provided on the side of the flow divider box. The output end of the valve is connected to the air inlet.

[0008] Preferably, the cleaning assembly includes a cleaning plate and a spring. The cleaning plate is arranged at the bottom of the upper mold, and a plurality of cleaning openings are provided at the bottom of the cleaning plate. The push rod passes through the cleaning openings and slides with the cleaning plate. The spring is arranged between the cleaning plate and the upper mold, and both ends of the spring are fixedly connected to the cleaning plate and the upper mold, respectively.

[0009] Preferably, the positioning component includes a positioning rod and a positioning sleeve. The positioning rod is arranged on the side of the lower mold, and the positioning sleeve is arranged on the side of the upper mold. The positioning rod and the positioning sleeve are inserted into each other and slide together.

[0010] Preferably, the bottom of the lower mold has a through groove, the through groove is connected to the recess, a storage box is slidably disposed inside the through groove, and the storage box has several pressure relief holes.

[0011] Preferably, the valve is an electrically controlled valve.

[0012] Preferably, the upper mold and the lower mold are provided with mounting brackets on their sides that are far apart from each other, and the mounting brackets are provided with a plurality of mounting openings.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. This solution uses a top rod and a notch to work together. The edges of the top rod and the notch are used to form a shear surface for punching holes in the sofa fabric. After punching, the waste fabric will fall through the notch. Some of the waste fabric will get stuck inside the notch. By blowing air into the notch using an air blowing component, the waste fabric stuck inside the notch will be blown out, avoiding long-term accumulation that could affect subsequent processing. At the same time, the cleaning component can clean the surface of the top rod, preventing threads from getting tangled on the surface of the top rod and extending the service life of the top rod and the notch.

[0015] 2. High-pressure gas from the outside enters the distribution box and is dispersed into various air channels through the air inlet. The high-speed flow of gas cleans the waste fabric inside the recess. Valves are used to control the opening and closing of the air inlet.

[0016] Third, the cleaning plate moves, causing the cleaning port to move. The cleaning port cleans the surface of the top rod. At the same time, the cleaning plate can be reset by the force of the spring and the gravity of the cleaning plate.

[0017] IV. The design of the positioning sleeve and positioning rod is used for positioning between the upper and lower molds.

[0018] 5. The channel is used to collect the waste fabric that falls into the notch. It is collected in a collection box to avoid subsequent handling. The pressure relief hole facilitates the discharge of air blown out of the notch to avoid high pressure and ensure safety.

[0019] VI. The valves are electrically controlled, which can be opened without manual intervention. They can be connected to the control system of external equipment for automatic opening and closing, which not only improves the level of intelligence but also reduces human error, and can significantly improve production efficiency in large-scale production.

[0020] 7. The mounting bracket and mounting port are used to connect the upper and lower dies to an external press. Attached Figure Description

[0027] Example 1:

[0028] Please see Figure 1-4 A permeable forming mold for an antistatic breathable sofa fabric includes an upper mold 1 and a lower mold 2. The upper mold 1 is located above the lower mold 2 and the upper mold 1 and lower mold 2 are adapted to each other. A mounting frame 19 is provided on the side of the upper mold 1 and the lower mold 2 that are far apart from each other. The mounting frame 19 has several mounting holes 20. The upper mold 1 and the lower mold 2 can be easily connected to a press through the mounting holes 20 and the mounting frame 19. A positioning component 3 is provided between the upper mold 1 and the lower mold 2. The positioning component 3 includes a positioning rod 14 and a positioning sleeve 15. The positioning rod 14 is arranged on the side of the lower mold 2 and the positioning sleeve 15 is arranged on the side of the upper mold 1. The positioning rod 14 and the positioning sleeve 15 are inserted into each other and slide in fit. The positioning sleeve 14 and the positioning rod 14 are designed for positioning between the upper mold 1 and the lower mold 2.

[0029] The bottom of the upper mold 1 is evenly provided with several push rods 4, and the top of the lower mold 2 is evenly provided with several notches 5. The notches 5 and the push rods 4 correspond to and fit each other. The push rods 4 and the notches 5 cooperate to form a shear surface through the edge of the end face of the push rod 4 and the edge of the notch 5, which is used to punch holes in the sofa fabric. One end of the push rod 4 is provided with an air passage 6. The upper mold 1 is provided with an air blowing assembly 7 for supplying air to the air passage 6. The air blowing assembly 7 includes a flow divider box 9 and a valve 10. The flow divider box 9 is installed between the upper mold 1 and the corresponding mounting bracket 19. The flow divider box 9 is provided with several air ports 21. Corresponding to air passage 6, the side of the diversion box 9 has an air inlet 22. The output end of valve 10 is connected to the air inlet 22. It is connected to the external compressed gas pipeline through valve 10. Valve 10 is a switch to control the compressed gas to enter the interior of the diversion box 9. Valve 10 is an electrically controlled valve. The design of the electrically controlled valve can be easily operated by an external controller without manual opening, ensuring safety. After the external high-pressure gas enters the interior of the diversion box 9, it will enter each air passage 6 through air port 21, thereby blowing the waste fabric inside the recess 5 downward through the high-pressure gas.

[0030] A through groove 16 is formed between the bottom of the lower mold 2 and the corresponding mounting bracket 19. The through groove 16 is connected to the recess 5. A storage box 17 is slidably arranged inside the through groove 16. Several pressure relief holes 18 are opened on the storage box 17. The through groove 16 is used to collect the waste fabric that falls from the recess 5. The waste fabric is collected in a concentrated manner through the storage box 17 to avoid subsequent handling. The pressure relief holes 18 facilitate the discharge of the gas blown out of the recess 5 to avoid high pressure and ensure safety.

[0031] The bottom of the upper mold 1 is provided with a cleaning component 8 for cleaning the surface of the upper mold 1. The cleaning component 8 includes a cleaning plate 11 and a spring 12. The cleaning plate 11 is arranged at the bottom of the upper mold 1, and several cleaning holes 13 are opened at the bottom of the cleaning plate 11. The ejector rod 4 passes through the cleaning holes 13 and slides with the ejector rod 4 and the cleaning plate 11. The spring 12 is arranged between the cleaning plate 11 and the upper mold 1. The two ends of the spring 12 are fixedly connected to the cleaning plate 11 and the upper mold 1, respectively. The bottom of the lower mold 2 is provided with a placement opening for storing the spring 12, so that the cleaning plate 11 can be completely attached to the bottom of the upper mold 1. During the operation of the mold, the cleaning component 8 can effectively clean the surface of the ejector rod 4. After cleaning, the amount of contaminant residue on the surface of the ejector rod 4 is reduced, which effectively extends the service life of the ejector rod 4.

[0032] Working principle:

[0033] In use, the upper mold 1 is fixedly connected to the power end of the press, and the lower mold 2 is fixedly connected to the operating end of the press. Simultaneously, valve 10 is connected to the control cabinet of the press. The fabric is laid flat on the upper surface of the lower mold 2. When the press is started, it will drive the upper mold 1 downwards, creating a hole in the fabric through the cooperation of the notch 5 and the push rod 4. The cut-off waste fabric will fall into the notch 5. When the output end of the press is at its lowest point, the press control system will open valve 10, thereby releasing the external high pressure. Gas enters the diversion box 9 and then enters the recess 5 through the air inlet 21 and air passage 6. High-pressure gas blows the waste gas cloth inside the recess 5 into the collection box 17 located at the bottom of the recess 5. The valve 10 can be automatically closed 3-5 seconds after starting by the delay module in the control cabinet to avoid wasting resources. The pressure relief port on the side of the collection box 17 can discharge the gas to avoid excessive pressure and ensure safety. The collection box 17 plays a collection role, and the cooperation between the collection box 17 and the through groove 16 makes it easy to remove.

[0034] When the upper mold 1 and the lower mold 2 come into contact, the cleaning plate 11 is pushed upward. When the drilling is completed and the upper mold 1 is reset, the cleaning plate 11 is reset downward under its own weight and the elastic force of the spring 12, so as to clean the side of the push rod 4 through the cleaning port 13.
