The invention has the beneficial effects that: after the hot-melt support framework layer is formed by utilizing the shaping mould, any shell type appearance effect (furniture, lamps and artworks) can be manufactured by the scheme, under the condition of consistent basic appearance, the shape of the hot-melt support framework layer is more abundant and changeable, the same and different feelings are achieved, the individuation is strong, and the requirement that each consumer enjoys the unique feeling of the product is met.
Description
Technical Field
The invention relates to a plastic product, in particular to a manufacturing method of the plastic product.
Background
As is well known, wood resources are now less and less, and it is more and more difficult to meet the increasing demand of people, so that the technical personnel in the field use plastics to replace wood materials to make plastic furniture or artworks. However, the existing plastic furniture or artware is usually manufactured by adopting a fixed mold production mode, each product is uniform, the appearance is stiff, and the personalized requirements of consumers are difficult to meet, so that further transformation is necessary.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a manufacturing method of a plastic product which is simple in structure, variable in shape, strong in bearing capacity and rich in appearance effect and is invisible.
The object of the invention is achieved in the following way: a method for manufacturing a plastic product is characterized in that: the method comprises the following steps:
a: manufacturing a bottom die similar to the shape of a finished product;
b: spraying and forming a framework layer on the surface of the bottom die by a plastic spinning process, wherein the framework layer is required to be made of transparent or reflective plastic;
c: and demolding after the framework layer is cooled and solidified.
In the plastic spinning process, the cross section of the jetted plastic filament is circular.
In the plastic spinning process, the cross section of the jetted plastic filament is elliptic.
In the plastic spinning process, the cross section of the ejected plastic filament is in an irregular shape.
The framework layer can be arranged into one layer or multiple layers according to the stress requirement of the framework layer.
The invention has the beneficial effects that: 1. simple structure, low production cost and improved market competitiveness. 2. After the hot-melt support framework layer is formed by utilizing the shaping mould, any shell type appearance effect (furniture, lamps and artworks) can be manufactured by the scheme, under the condition of consistent basic appearance, the shape of the hot-melt support framework layer is more abundant and changeable, the same and different feelings are achieved, the individuation is strong, and the requirement that each consumer enjoys the unique feeling of the product is met. 3. The product shell is integrally formed by mutually adhering plastic spinning yarns, and the adhesion part of the product shell has a complex and changeable stressed structure, so that the product produced by the process has stronger bearing capacity under the condition of the same thickness. 4. The light-transmitting or light-reflecting material can enable all parts of the product to generate different light effects under the action of light, so that the characteristics of the product are created.

FIG. 1 is a sectional view of the structure of the present invention.
FIG. 2 is a schematic view of the assembly effect of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. A method for manufacturing a plastic product is characterized in that: the method comprises the following steps:
a: manufacturing a bottom die 1 similar to the shape of a finished product;
b: spraying and forming the framework layer 2 on the surface of the bottom die 1 by a plastic spinning process, wherein the framework layer 2 is required to be made of transparent or reflective plastic;
c: and demolding after the framework layer 2 is cooled and solidified.
In the plastic spinning process, the cross section of the jetted plastic filament is circular.
In the plastic spinning process, the cross section of the jetted plastic filament is elliptic.
In the plastic spinning process, the cross section of the ejected plastic filament is in an irregular shape.
The framework layer can be arranged into one layer or a plurality of layers according to the stress requirement of the framework layer 2.
The working principle is as follows: in practical production, a user needs to set a bottom die with a corresponding shape for modeling, and then a skeleton layer is formed on the surface of the bottom die by spraying through a plastic spinning process, wherein the skeleton layer requires that plastic spinning is spiral as the best, and the thickness can be freely controlled. And after the hot framework layer is cooled and solidified, demolding the support framework layer for use.
Compared with the prior art, the framework layer in the scheme is formed by plastic spinning of transparent or reflective plastic, the framework layer can be arranged into one layer or multiple layers according to the stress condition of a product, and the thickness of each layer can be freely controlled. In the spinning of each layer of framework layer, the spinning yarns are adhered to each other, so that a complex multi-point supporting structure can be formed, and products produced by the process have higher supporting force in terms of the same thickness, thereby playing the roles of saving materials and reducing the weight of the products. In addition, the surface of the product produced by the process has regular or irregular textures or even hollow parts, and compared with the traditional injection molding product, the product has stronger surface stereoscopic impression and more novelty in overall appearance, thereby being capable of arousing the purchasing desire of users, and being widely popularized and used.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
