Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a steam thermoforming punching die for a front spare tire tank liner. Background Technology

[0002] The front spare tire well guard plate is mainly used to protect the spare tire well area under the vehicle from impacts by mud, water, and gravel. In the steam thermoforming die for the front spare tire well guard plate, the steam thermoforming process uses high-temperature and high-pressure steam to quickly and evenly heat the plastic sheet, softening it. Then, within the same mold, the formed part is precisely cut from the sheet scrap by using air pressure (positive pressure, negative pressure, or a combination of both) in the same mold and by using a punching blade (steel blade or hardened insert).

[0003] The existing steam thermoforming die for front spare tire liner has poor material flowability, especially in the deep cavity area of ​​the mold, where the filling speed is slow, which makes it difficult to improve processing efficiency. In addition, due to different materials, some plastic materials (such as PP and ABS) may not require excessively high steam temperatures during molding (e.g., steam temperature exceeding the material softening point by too much), which makes it difficult to ensure the quality of the front spare tire liner molding.

[0016] (III) Beneficial Effects

[0017] This utility model provides a steam thermoforming and punching die for a front spare tire well panel, which has the following advantages:

[0018] 1. This front spare tire tank liner steam thermoforming die, through the setting of a cooling component, connects the steam delivery pipe to the steam source and the external connection pipe to the cooling water source during use. According to the material of the stamping material, a high-precision temperature sensor detects the temperature of the steam. If the temperature exceeds the monitored threshold, a signal is sent to the PLC controller. The PLC controller controls the intelligent delivery pump to turn on, and low-temperature water is delivered to the atomizing nozzle pipe, atomized, and sprayed into the steam delivery pipe for evaporation and cooling. This achieves the effect of changing the steam temperature, avoiding the need for excessively high steam temperatures (e.g., steam temperature exceeding the material's softening point) when molding certain plastic materials (such as PP and ABS). Cooling can prevent material degradation or surface defects (such as bubbles or scorching), helping to ensure the quality of the front spare tire tank liner molding.

[0019] 2. This steam thermoforming die for the front spare tire well liner, through optimized component settings, utilizes high-temperature, high-pressure steam to rapidly and uniformly heat the plastic sheet, softening it. Then, a vibration motor is activated, using the centrifugal force generated by the high-speed rotation of the shaft and eccentric block to produce vibration, increasing the fluidity of the softened material and achieving rapid filling. This avoids issues caused by weak material fluidity, especially in the deep cavity area of ​​the front spare tire well liner die, thus improving processing efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a steam thermoforming punching die for a front spare tire well guard plate, comprising an upper die 1 and a lower die 2. Steam channel pipes are provided inside the upper die 1 and the lower die 2. A steam connection port 3 is fixedly connected to one end of the steam channel pipe, and a cooling component 4 is fixedly connected to one end of the steam connection port 3. Optimization components 5 are fixedly connected to both sides of the lower die 2.

[0027] The cooling component 4 includes a connecting pipe 401, a steam delivery pipe 402, a high-precision temperature sensor 403, a vertical pipe 404, an atomizing nozzle pipe 405, and a PLC controller 406. With the cooling component 4 in place, the steam delivery pipe 402 is connected to a steam source, and the external connecting pipe 10 is connected to a cooling water source. Based on the material of the stamping material, the high-precision temperature sensor 403 detects the steam temperature. If the temperature exceeds the monitored threshold, a signal is sent to the PLC controller 406. The PLC controller 406 then controls the intelligent delivery pump 9 to open, delivering low-temperature water to the atomizing nozzle pipe 405, atomizing it, and spraying it into the steam delivery pipe 402 for evaporative cooling. This achieves the effect of changing the steam temperature, avoiding the need for excessively high steam temperatures (e.g., steam temperatures exceeding the material's softening point) during molding of certain plastic materials (such as PP and ABS). Cooling prevents material degradation or surface defects (such as bubbles or scorching), helping to ensure the quality of the front spare tire tank liner molding.

[0028] The optimized component 5 includes a vibration motor 501 and an eccentric block 502. By optimizing the component 5, the plastic sheet is heated quickly and evenly by high-temperature and high-pressure steam during use, softening it. Then, the vibration motor 501 is started, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block 502 is used to generate excitation force and produce vibration. This increases the fluidity of the softened material, thereby achieving the purpose of rapid filling. This avoids the problem of poor material fluidity, especially in the deep cavity area of ​​the front spare tire tank liner mold, and helps to improve processing efficiency.

[0029] The top surface of the upper mold 1 is fixedly connected to the upper mold base 6, and the bottom surface of the lower mold 2 is fixedly connected to the lower mold base 7. The arrangement of the upper mold base 6 and the lower mold base 7 facilitates the installation of the molds on the steam thermoforming equipment for the front spare tire tank liner.

[0030] The upper mold 1 has a punching cutter embedded around its bottom surface, and the lower mold 2 has a punching groove on its top surface that matches the punching cutter. The punching cutter and the punching groove together serve as a spare tire well guard before punching.

[0031] The cooling component 4 includes a connecting pipe 401 fixedly connected to one end of the steam connection port 3. A steam conveying pipe 402 is fixedly connected to one end of the connecting pipe 401. A high-precision temperature sensor 403 is fixedly installed on the top surface of both the connecting pipe 401 and the steam conveying pipe 402. A vertical pipe 404 is fixedly connected to the top of the steam conveying pipe 402. An atomizing nozzle pipe 405 is fixedly connected to the top surface of the vertical pipe 404. The high-precision temperature sensor 403 is connected to a PLC controller 406 via an electrical signal. The cooling component 4 reduces the steam temperature.

[0032] A low-temperature water delivery pipe 8 is fixedly connected to one end of the atomizing nozzle pipe 405, and an intelligent delivery pump 9 is fixedly connected to one end of the low-temperature water delivery pipe 8. The atomizing nozzle pipe 405 is designed to deliver cooling water.

[0033] The input end of the intelligent transfer pump 9 is fixedly connected to an external connecting pipe 10, which is used to connect to an external cooling water source. Through the setting of the external connecting pipe 10, it plays the role of transporting steam.

[0034] The optimization component 5 includes a vibration motor 501 fixedly connected to both sides of the lower mold 2. The output end of the vibration motor 501 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to an eccentric block 502. By setting up the optimization component 5, the filling speed is increased.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: During use, the steam delivery pipe 402 is connected to the steam source, and the external connection pipe 10 is connected to the cooling water source. According to the material of the stamping material, the high-precision temperature sensor 403 detects the temperature of the steam. If the temperature exceeds the monitored threshold, a signal is sent to the PLC controller 406. The PLC controller 406 controls the intelligent delivery pump 9 to turn on, and low-temperature water is delivered to the atomizing nozzle pipe 405, atomized, and sprayed into the steam delivery pipe 402 for evaporation and cooling.

[0037] The second step: During use, the plastic sheet is heated quickly and evenly by high-temperature and high-pressure steam to soften it. Then, the vibration motor 501 is started, and the centrifugal force generated by the high-speed rotation of the shaft and eccentric block 502 is used to generate the excitation force, produce vibration, and increase the fluidity of the softened material.
