Embodiment Construction
[0050] Now in conjunction with accompanying drawing, the present invention will be further described:
[0051] As shown in the figure, a cooling and shaping mold for automobile sound insulation and noise reduction cotton, including:
[0052] The mold frame 7, whose shape is adapted to the sound-proof and noise-absorbing cotton of the automobile, is used to place the sound-proof and noise-absorbing cotton of the automobile. The mold frame 7 is provided with a plurality of positioning holes 71, and the positioning holes 71 correspond to the through holes on the sound-proof and noise-absorbing cotton of the automobile;
[0053] The guide groove 4 is fixed relative to the formwork 7, and is vertically located above the middle part of the formwork 7;
[0054] The guide rail 3 can only move up and down along the guide groove 4, and the guide rail 3 is provided with a rack;
[0055] Motor 1, the housing is fixed to the guide groove 4, the rotating shaft is fixed to the gear 2, and t...

The invention discloses a cooling forming die of automotive soundproof silencing cotton. The cooling forming die comprises a die set, a guide groove, a guide rail, a motor, a lifting plate and a plurality of pins. The die set is matched with automotive soundproof silencing cotton in shape and is used for placing the automotive soundproof silencing cotton; a plurality of positioning holes are formed in the die set and correspond to through holes in the automotive soundproof silencing cotton; the guide groove is fixed relative to the die set and is vertically formed in a position above the middle of the die set; the guide rail can move up and down only along the guide groove; a rack is arranged on the guide rail; the shell of the motor is fixed with the guide groove, a rotary shaft is fixed with a wheel gear, and the wheel gear is meshed with the rack; the lifting plate is fixed with the lower end face of the guide rail; the pins are the same as the positioning holes in number and are fixed with the lifting plate; and when the automotive soundproof silencing cotton is placed on the die set, the motor is controlled, so that the pins move up and down along with the guide rail and the lifting plate to penetrate through the through holes in the automotive soundproof silencing cotton and to be inserted in the positioning holes to position the automotive soundproof silencing cotton. The cooling forming die has the beneficial effects of simple structure, low cost, high application convenience and good shaping effect.
