Abstract
The invention relates to a manufacturing method for a wood plastic part used for automobiles. According to the invention, two layers of wood plastic materials are put in a baking oven for heating and softening; surface materials are placed in an upper die and a lower die; after the two layers of softened wood plastic materials are titled in the lower die, die locking is controlled, and air is blew between the two layers of wood plastic materials; boundary materials of an obtained part is removed; plastic parts are adhered to the obtained part and a spacing rope is installed so as to obtain a product. Compared to a common part with a single layer structure manufactured in the prior art, the part manufactured in the invention guarantees same strength on one hand, and enables materials to be saved and reduced weight to be obtained on the other hand since a double layer hollow structure is employed.
Description
Technical field
The present invention relates to part processing and make the field, especially relate to the preparation method of a kind of automobile with the Wood-plastic material part.
Background technology
The luggage case of automobile industry adopts single layer structure mostly at present, so structure is weak; Hardness and intensity are lower, reach certain intensity requirements if desired, then need increase the thickness of part etc.; Cause pts wt to lay particular stress on, make the load of automobile increase, thereby be unfavorable for automobile starting, go; Also can cause oil consumption to increase in addition, be unfavorable for environmental protection.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of preparation method of saving the automobile of material, reduction weight with the Wood-plastic material part to be provided.
The object of the invention can be realized through following technical scheme:
A kind of automobile is characterized in that with the preparation method of Wood-plastic material part this method adopts double-deck hollow structure moulding, and softening two-layer Wood-plastic material up and down is close to die cavity up and down under the pressure of intermediate gas, thereby moulding obtains product.
A kind of automobile is with the preparation method of Wood-plastic material part, and this method specifically may further comprise the steps:
(1) utilize water-cooling system, the temperature of control mold and bed die is 30～50 ℃;
(2) two-layer Wood-plastic material is put into the baking oven thermoplastic;
(3) placement surface material in mold and bed die;
(4) will dry by the fire soft two-layer Wood-plastic material is tiled in the bed die;
(5) with mold and bed die matched moulds, open blowning installation simultaneously, 2～3min blows in the middle of two-layer Wood-plastic material;
(6) blow to finish after, said modules is taken out, remove the rim charge that obtains part, then bonding plastics spare and spacing rope is installed is promptly obtained product on part.
Oven temperature is controlled to be 200～260 ℃ in the said step (2).
Surperficial carpet is laid on top in the said step (3) in the mold, and nonwoven is laid in the bottom in the bed die.
The air pressure of blowning installation is 0.7～1.2MPa in the said step (5).
Compared with prior art, the present invention makes the part that obtains and compares with common single layer structure part, can guarantee same intensity on the one hand, on the other hand, owing to adopt double-deck hollow structure, therefore can save material, and reduce the weight of part.
