Detailed description of the invention
Shown in Fig. 1 is a kind of tangent plane structural representation improving the embodiment of the mould of car carpeting surface quality provided by the utility model, mold integral is the rectangular structure of rule, adopting the mould of the improvement car carpeting surface quality of this kind of patten's design can enable to be installed on more easily on mold base when producing car carpeting, facilitating carpet fabric can be smoothly through the mould of the improvement car carpeting surface quality that the utility model provides.The structure composition of the mould of the improvement car carpeting surface quality that the utility model provides comprises hot pressing patrix 1, hot pressing counterdie 2 and liner 7, and wherein liner 7 is arranged between hot pressing patrix 1 and hot pressing counterdie 2.Carrying out in car carpeting production process, the carpet fabric 6 for the production of car carpeting is being placed on liner 7.When being layed on liner 7 by carpet fabric 6, to keep smooth as far as possible, reducing between liner 7 and carpet fabric 6 and producing space, otherwise can produce obvious gas bag when carrying out hot pressing.
The one side that hot pressing patrix 1 and the carpet fabric 6 of the mould of the improvement car carpeting surface quality that the utility model provides are fitted is plane, the hot pressing patrix 1 when producing car carpeting can be contacted fully with carpet fabric 6, avoiding in hot pressing due to hot pressing patrix 1 and the uneven car carpeting surface irregularity causing producing of carpet fabric 6 contact surface.Described precoat is by styrene monomer and the amorphous polymer of rubber graft polymerization or the physical blending thing of polystyrene and rubber, namely the copolymer of polystyrene or blend are formed, and make whole carpet fabric 6 layers have good formability and erosion-resisting characteristics.
What the liner 7 of the mould of the improvement car carpeting surface quality that the utility model provides adopted is foaming liner.The foaming hardness of liner and modest viscosity, anti-collision is functional, and the excellent toughness of the performance of intensity splendid for polyethylene and oil resistant fat and chemicals and polystyrene, compression strength and processing characteristics combine by this kind of gasket material.
Adopt the car carpeting of pre-buried foaming liner hot-pressing technique, usually liner 7 dorsad hot pressing patrix 1, design different moulding 8 from the part that hot pressing counterdie 3 is fitted for coordinating other gadgets, because the integral foam multiplying power (compression ratio) of liner 7 is consistent, liner 7 thickness at moulding 8 place is larger, when being stressed consistent, the Part portions decrement that thickness is large is larger.In the process of hot pressing matched moulds, the air between liner 7 and carpet fabric 6 can four loose discharges.But at this moment the not timely deaeration of a part may be gathered in the large position of liner 6 decrement, cause comprising some air between carpet fabric 6 and liner 7 and causing carpet surface produce gas bag and cause uneven, the mould of the improvement car carpeting surface quality that the utility model provides avoids the generation of this phenomenon.
