Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cotton board processing technology, and in particular relates to a multi-layer mold for producing automotive sound insulation and heat insulation cotton. Background Technology
[0002] Sound and heat insulation cotton has excellent heat insulation properties. When applied inside the car hood, it effectively prevents the engine's high temperature from being directly transferred to the hood, thus protecting the paint on the hood surface. It also prevents fogging on the hood from obstructing visibility in rainy weather, reduces engine noise, lowers noise levels, improves vehicle noise reduction and ride comfort, alleviates metal fatigue in the car chassis, and helps extend the car's lifespan. Metal fatigue usually stems from unevenness in the internal structure of the metal; the addition of sound insulation cotton helps reduce this stress concentration, thereby slowing down the process of metal fatigue. Sound and heat insulation cotton also has excellent waterproof properties, helping to prevent rust on the car body panels.
[0003] A search revealed that patent document CN215511398U discloses a multi-layer mold for producing heat and sound insulation cotton for automotive roofs. The mold includes a bottom template with supporting legs fixedly connected to it. Supporting pads are fitted onto the bottom of the supporting legs. Multiple templates are connected above the bottom template, and grooves are formed at the bottom of each template. This multi-layer mold for producing heat and sound insulation cotton for automotive roofs features a bottom template and multiple templates, giving it a multi-layered structure. Multiple templates work together, improving production efficiency. A demolding template is located inside the mold groove. A hydraulic cylinder inside the template drives a movable rod to extend and retract, which in turn moves a sliding rod up and down within the bottom and multi-layer templates, further raising and lowering the demolding rod. This allows control over the raising and lowering of the demolding template, which ejects the sound insulation cotton from the mold groove, making demolding more convenient and further improving processing efficiency.

[0032] A positioning plate is provided on one side of the main body 1. A motor 21 is fixedly installed on the positioning plate.

[0034] The working principle of the multi-layer mold for producing automotive sound and heat insulation cotton provided by this utility model is as follows:
[0035] First step: Proximity sensors are installed on frame 10, frame 21, and the main body 1. The feeding pipe 8 has a feed hose connected to an external material pump. The air duct 20 and hollow plate 24 each have two air inlet hoses connected to an external air pump. During the production of sound and heat insulation cotton, the two motors 22 start first, driving the gears 13 on both sides to rotate, thereby causing frame 10 and frame 21 to move back and forth. This, combined with the up-and-down movement of the hydraulic telescopic rod, allows for staggered feeding and replenishment. When any frame moves to the rear... Material replenishment is performed by external machines or manually. When any frame moves forward, the hydraulic telescopic rod sinks, causing the proximity sensor on the frame to approach and trigger the proximity sensor on the main body 1, which sends a signal to retract the electric telescopic rod 16. This causes the upper clamping plate 15 to lose its pressure and separate from the lower clamping plate 14, allowing the material on the frame to be placed on the concave bottom template 2. The two frames move alternately until the material is placed. At the same time as the material is being laid, the spray pipe 8 moves back and forth with the cooperation of the motor 3 and the threaded rod 4 to spread the adhesive, which facilitates subsequent bonding.
[0036] The second step: After each new layer of material is laid, before the adhesive is applied, the upper template 19 is pressed down by the hydraulic pressure rod to press the material on the concave bottom template 2. At the same time, an external air pump inflates the air pipe 20 and blows it out through multiple flat nozzles to blow off the residue on the concave bottom template 2, preventing it from being pressed into the cotton board. Then the upper template 19 is retracted and waits for the material to be laid before pressing down again. When the cotton board is completely made, with the cooperation of motor 3 21 and electric telescopic rod 22, the cotton board is lifted and transferred by the cooperation of external air pump and suction cup 25.
