There is connects bayonet socket.
Optionally, the described car insurance is comprised the following steps that with the production method of noise box:
A, proportion injection molding ingredient, is made PU liquid charging stock；
B, release agent is sprayed；
C, material feeding；
D, contracting mold insert；
E, it molds；
F, it is opened；
G, mold insert is pushed up；
H, product is taken out.
Optionally, the plastics of the noise box are that two kinds of ingredients mix, and two kinds of ingredients are respectively A ingredient and B ingredient.
Optionally, the A ingredient of the noise box is as follows: wherein 330 type polyethers 65%, H45 type polyethers 35%, diethanol amine
3.5%, triethanolamine 1%, water 1.2%, ethylene glycol 1.15%, HP type catalyst 0.6%, A33 type catalyst 0.3% and B-
8715 type silicone oil 0.3%.
Optionally, the B ingredient of the noise box is as follows: wherein liquefy polyurethane 60%, polymerizable polyurethane 10% and pre-polymerization
Polyurethane 30%.
Optionally, the injection molding panel material is pre-fabricated as PU liquid charging stock.
Optionally, the safety belt noise box is in injection moulding process, sets mold temperature as between 50~60 DEG C, injection pressure
Power is 0.7~0.9kbar, sets targetedly cast gate quantity to different size safety belt noise box.
The present invention provides a kind of car insurance band noise box and its production methods to have following compared with traditional approach
The utility model has the advantages that
The car insurance is used for the noise reduction of car insurance band with noise box, may be mounted at corresponding position, reduces safety belt
The noise issued when pull-out or withdrawal improves user of service's comfort level, and properties of product are relative to common insurance
Band noise box greatly improves, and appearance is beautiful, and sound insulation value is perfect, and product indices have all reached the requirement of automotive check,
The odor requirements that especially all automobiles are all paid close attention to, be compared to material not environmentally, odor detection general insurance band not up to standard
Noise box, car insurance band noise box can pass through odor detection project, more safety and environmental protection, while when manufacturing,
The control time of technique is controlled by computer disk, can be realized standard component, and quality is reliable and stable, and it is real to manufacture overall process
Standardization industrial production is showed, production efficiency is higher, and the quality of production is more stable.
Detailed description of the invention
