Abstract
Description
Technical Field
[0001] This utility model relates to the field of punching die technology, and in particular to a thermoforming punching die for sound insulation pads. Background Technology
[0002] Sound insulation pads are typically composed of multiple layers of composite materials, such as foam, rubber, fiber, and aluminum foil. These materials possess excellent sound insulation properties, effectively absorbing or blocking sound transmission. With increasing noise control requirements in the automotive, construction, and home furnishing industries, the demand for sound insulation materials is growing daily. As an important noise reduction material, sound insulation pads are widely used in automotive flooring, roof, and doors to reduce external noise and interior vibration, improving passenger comfort and driving experience. Furthermore, sound insulation pads are also used in building decoration for sound insulation and noise reduction of walls, ceilings, and floors.
[0003] A sound insulation pad forming punching die disclosed in CN110757773A includes a die body and a punching blade. The die body has multiple slots at narrow locations where the punching blade needs to be installed. The punching blade is installed onto the die body via connectors passing through these slots. This invention eliminates the need to create slots where a fitter would normally drill a side hole at narrow locations for the punching blade. The punching blade is then installed onto the die body through these slots, eliminating the need to remove inserts. The slots are integrated with the die body, reducing costs and improving work efficiency.
[0004] However, the thermoforming die for the sound insulation pad has the following disadvantages: during the thermoforming process of the sound insulation pad, some materials and dust will accumulate and adhere to the surface of the die, affecting the temperature conduction and forming accuracy of the die, resulting in unstable product dimensions, affecting overall production efficiency, and reducing the service life of the die. Utility Model Content

[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a thermoforming and punching die for sound insulation pads, comprising a mother template, a lower fixing plate fixedly connected to the bottom of the mother template, a dust removal component fixedly connected to one end of the lower fixing plate, and a cooling component fixedly connected to the other side of the mother template; the dust removal component includes a diversion pipe fixedly connected to one end of the mother template, a cyclone separator fixedly connected to one side of the diversion pipe, and a dust collection bin fixedly connected to the bottom of the cyclone separator; the cooling component includes a cooling box fixedly connected to the other side of the lower fixing plate, a radiator fan fixedly connected to one side of the cooling box, and a coolant hose fixedly connected to the other side of the cooling box.
[0009] As a further embodiment of this invention, a dust collection pipe is fixedly connected to one side of the diversion pipe, and a connecting pipe is fixedly connected to one side of the dust collection pipe. A cyclone motor is fixedly connected to the top of the cyclone, and multiple sets of support feet are fixedly connected to the surface of the cyclone. The cyclone's design allows residue and dust from the mold surface to be drawn into its interior, forcing the airflow to rotate along the inner wall of the cylinder. Due to centrifugal force, the residue and dust are thrown against the cylinder wall, falling down into the dust collection bin and ultimately being discharged through the dust exhaust hood.
[0010] As a further embodiment of this utility model, a support circular plate is fixedly connected to the bottom of the support foot, and multiple sets of support legs are fixedly connected to the bottom of the support circular plate. Foot pads are fixedly connected to the bottom of the support legs. The support foot configuration enhances the stability of the cyclone.
[0011] As a further embodiment of this utility model, an output pipe is fixedly connected to the bottom of the cyclone, an input pipe is fixedly connected to the top of the dust collection bin, and a dust exhaust hood is fixedly connected to the bottom of the dust collection bin. The dust exhaust hood enables the timely discharge of residues and dust from the dust collection bin.
[0012] As a further embodiment of this utility model, an inlet pipe is fixedly connected to the top of the cooling box, a temperature controller is fixedly connected to one side of the cooling box, a telescopic pipe is fixedly connected to one side of the cooling box, and a water pump is fixedly connected to one end of the telescopic pipe. By setting the temperature controller, the stability of the mold temperature can be effectively controlled, and a stable thermal environment for the mold can be maintained.
[0013] As a further embodiment of this utility model, multiple sets of partition plates are fixedly connected to both sides of the mother template, and an upper fixing plate is fixedly connected to the top of the partition plates. The partition plates provide a certain buffer space and distance between the mother template and the child template.
[0014] As a further embodiment of this utility model, a movable plate is fixedly connected to the bottom of the upper fixed plate, and a sub-template is fixedly connected to the bottom of the movable plate. Multiple sets of blades are fixedly connected to the outside of the sub-template. The blades are used to remove excess material from the sound insulation pad.
[0015] (III) Beneficial Effects
[0016] This utility model provides a thermoforming and punching die for sound insulation pads, which has the following beneficial effects:
[0017] 1. This sound insulation pad thermoforming punching die, through the setting of the dust removal component, when it is necessary to clean the residue and dust on the surface of the die, the cyclone motor is activated to generate a strong airflow. This airflow will carry the residue and dust on the surface of the die into the internal channel of the mother mold through the surface hole of the mother mold, and then be sucked into the diversion pipe, then into the dust collection pipe, then into the cyclone, and finally to the dust collection bucket, and discharged through the dust exhaust hood. This effectively removes the residue and dust accumulated and adhered to the surface of the die, prevents it from affecting the temperature conduction and forming accuracy of the die, improves the dimensional accuracy of the product, and improves the overall production efficiency.
[0018] 2. This sound insulation pad thermoforming punching die, through its cooling components, directs coolant into a cooling tank. The coolant then enters a water pump via a telescopic pipe on one side of the cooling tank, and subsequently into a coolant hose embedded in the mother mold. The coolant, circulating through this hose, absorbs heat from the mold and transfers it back to the cooling tank. As the coolant flows through the cooling tank, the radiator fan accelerates heat dissipation and enhances airflow, allowing heat to dissipate more quickly. The absorbed heat is released through heat exchange with the air. The coolant flows through pipes within the cooling tank, and the surrounding air carries away heat, initiating a new heat exchange cycle. This continuous circulation of coolant effectively controls the temperature stability of the mold and sound insulation pad, maintaining a stable thermal environment, improving production efficiency and product quality, and extending the mold's lifespan.

A cyclone motor 7 is fixedly connected to the top of the cyclone 302, and multiple sets of support feet 8 are fixedly connected to the surface of the cyclone 302.
