Abstract
The utility model discloses a kind of continuous fiber thermoplastic composite plastic seat skeleton, and described cushion frame is made up of the support slot in gate truss and gate truss, and the support slot in described gate truss and gate truss is interconnected, and forms the overall groove be interconnected.Back of seat in the utility model, seat sitting face are one-body molded, and production efficiency is higher.Adopt continuous fiber and long fibre two kinds of fibers in seat sitting face, this set makes the layout of fiber and orientation complement each other, and substantially increases the strength-to-density ratio of sitting face, specific modulus and impact resistance.Use long fibre in reinforced rib, avoid the phenomenon that in compressing process, fiber easily ruptures, have lightweight compared with traditional back of seat, seat sitting face, the advantage that strength-to-density ratio, specific modulus and impact resistance are high.
Description
Technical field
The utility model belongs to automotive field, is specifically related to a kind of continuous fiber thermoplastic composite plastic seat skeleton.
Background technology
Along with the requirement of auto trade product weight-saving, the weight of client to product it is also proposed stricter requirement.The backrest frames overwhelming majority that automobile chair on market uses is metal backrest, and manufacturing procedure is complicated, spends more man-hour, energy resource consumption aspect, produces raw materials for plastics production than producing raw material metal and can save the more energy.The cost again utilized is less, pollutes hardly environment.The density that it has is little, the linear expansion factor of thermoplastic composite is less, the advantages such as the shrinkage percentage (precision of product size can be improved) in product molding process can be reduced and greatly extend composite material use in daily life, alternative metals and timber gradually, as the metal parts on car.But the intensity ratio intensity of plastics, specific modulus and shock resistance are strong, the product of preparation often service life shorter.The applying date is on November 27th, 2009, application number is the Chinese patent of 200910199483. 1, disclose a kind of car seat back frame of plastic material, described skeleton is integrated by plastic material, and described skeleton has the shell extended along its circumference, the horizontal sentence cross section of described shell is " n " type, and the inner side of the shell of described n tee section has cellular reinforced rib.Although reinforced rib be arranged on the service life that improve product to a certain extent, also differ greatly compared with the intensity of plastics and metalwork and impact property.
Summary of the invention
The purpose of this utility model is to provide the higher continuous fiber thermoplastic composite plastic seat skeleton of a kind of strength-to-density ratio, specific modulus and impact resistance.
For achieving the above object, the utility model is by the following technical solutions:
A kind of continuous fiber thermoplastic composite plastic seat skeleton, described cushion frame is made up of the support slot in gate truss and gate truss, and the support slot in described gate truss and gate truss is interconnected, and forms the overall groove be interconnected.
The material of described cushion frame is continuous fiber thermoplastic composite plastics.
Establish supporting rib stiffener in the groove that described entirety is interconnected, supporting rib stiffener is long fiber thermoplastic composite plastic.
The inside face of the groove groove that described entirety is interconnected is long fiber thermoplastic composite plastic.
Back of seat in the utility model, seat sitting face are one-body molded, and production efficiency is higher.Adopt continuous fiber and long fibre two kinds of fibers in seat sitting face, this set makes the layout of fiber and orientation complement each other, and substantially increases the strength-to-density ratio of sitting face, specific modulus and impact resistance.Use long fibre in reinforced rib, avoid the phenomenon that in compressing process, fiber easily ruptures, have lightweight compared with traditional back of seat, seat sitting face, the advantage that strength-to-density ratio, specific modulus and impact resistance are high.

Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of continuous fiber thermoplastic composite plastic seat skeleton, cushion frame is made up of the support slot in gate truss and gate truss, and the support slot in gate truss and gate truss is interconnected, and forms the overall groove 11 be interconnected.As shown in Figure 3, supporting rib stiffener 31 is established in the groove that entirety is interconnected; As shown in Figure 4, the inside face 41 of the groove groove that entirety is interconnected is long fiber thermoplastic composite plastic, and supporting rib stiffener is long fiber thermoplastic composite plastic, and the material of cushion frame is continuous fiber thermoplastic composite plastics.Long-fiber-reinforced thermoplastics is the rectangular of fully being flooded by resin of obtaining after resin dedicated dipping of long fibre, is then cut into the length of needs as required, is generally 20-30cm; Continuous fiber reinforced thermoplastic plastic is similar to Long-fiber-reinforced thermoplastics preparation method, and just continuous fiber reinforced thermoplastic plastic is uninterrupted along its length, can infinitely extend.
The job operation of continuous fiber thermoplastic composite plastic seat skeleton, comprises the steps:
Step one, makes the expansion drawing of cushion frame groove, cuts continuous fiber thermoplastic composite plastic sheet according to the shape of expansion drawing;
Step 2, sheet material step one sheared is heated to 200-240 DEG C;
Step 3, covers the former of cushion frame, as shown in 51 in Fig. 5, then the groove 53 of former 51 is placed in the middle part of sheet stock by the sheet material of at least one deck heating;
Step 4, sheet material is pressed into former by the formpiston of cushion frame, the groove making continuous fiber thermoplastic composite plastic sheet form entirety to be interconnected, molding pressure 1500-1800T/M
2, female mould temperature 30-80 DEG C, dwell time 40-90 second, the demoulding afterwards.
The step 4 not demoulding, extract formpiston, formed in groove that entirety is interconnected at continuous fiber thermoplastic composite plastic sheet and insert the long fiber thermoplastic composite plastic material strip being heated to 200-240 DEG C, with another in the overall groove be interconnected of formpiston press-in, this formpiston is arranged the groove that reinforced rib is corresponding, molding pressure 1500-1800T/M
2, female mould temperature 30-80 DEG C, dwell time 40-90 second, the demoulding is afterwards long fiber thermoplastic composite plastic supporting rib stiffener in the groove that entirety is interconnected.Because of mold pressing and temperature higher, can be moved to continuous fiber interface at mould pressing process medium length fibre, therefore, just there will be as in Fig. 4, the inside face of gate groove is long fibre 41.
