Description
Technical field
The present invention relates to case field, particularly relate to a kind of manufacture method of ABS/PC duricrust casing.
Background technology
The material that at present luggage case is on the market used is generally all nylon material or plastic material, comprises PP, ABS, PC etc.Wherein, the luggage case be made up of nylon material is referred to as commercial case, and the material of this casing is comparatively light, but cracky.In addition, the luggage case made by plastic material is referred to as hard shell trunk, and hard shell trunk is generally one-body molded, good to the article protection in casing.But current hard shell trunk is generally by two-layer plastic material injection moulding coextrusion mold, although the hard shell trunk hardness of preparation reaches user's requirement, wearability and impact resistance poor, cause casing short for service life.
Summary of the invention
In order to overcome above shortcoming, the object of this invention is to provide a kind of duricrust casing wearability of preparing and impact resistance is strong, the manufacture method of the ABS/PC duricrust casing of long service life.
For achieving the above object, the present invention by the following technical solutions: a kind of manufacture method of ABS/PC duricrust casing, described manufacture method comprises the following steps:
1) injection moulding sheet material: through injection machine co-extrusion obtain two-layer more than composite board, wherein one deck is ABS plate layer, and at least one deck PC sheet metal layer is superficial layer;
2) fit: at the coextruding die head end of injection machine, another PC overlay film is attached to PC sheet metal layer surface, and then the composite board after laminating is sent into extruding laminating between two compression rollers;
3) cutting: by through step 2) composite board after laminating cuts in flakes by case and bag housing size, obtains the cutting blade of composite board;
4) hot briquetting: the cutting blade of composite board step 3) obtained first is preheated to 40-60 DEG C, and then the cutting blade of composite board is put into forming machine, and by the cutting blade Four built in boundaries of composite board in the lower mode cavity of forming machine, cover upper cavity again, then up to be moved by air cylinder driven bed die and by cutting blade top to mold, mold and bed die coordinate makes cutting blade hot briquetting, cutting blade is taken out and obtains described ABS/PC duricrust casing.
Step 2 of the present invention) in, another PC overlay film is attached to the composite board surface formed by PC sheet metal layer and ABS plate layer co-extrusion at coextruding die head end, because the position of laminating is near coextruding die head end, so the composite board surface formed by PC sheet metal layer and ABS plate layer co-extrusion also remains with higher co-extrusion temperature, another PC overlay film operates without the need to extra heating with the laminating of the composite board formed by PC sheet metal layer and ABS plate layer co-extrusion like this, simplify processing technology, improve working (machining) efficiency.
The present invention adopts above manufacture method, has attached one deck PC overlay film in the hard shell trunk surface that tradition is two-layer, thus increases the wearability of hard shell trunk surface.Because PC overlay film is flexible material, also can improve hard shell trunk surface shock resistance, and then reach the object extending duricrust casing service life.
In the present invention, hardness because of ABS plate layer is greater than surperficial PC sheet metal layer, when the duricrust casing that client needs hardness larger, suitably can increase the thickness of ABS plate layer, when the duricrust casing that client needs hardness less, suitably can reduce the thickness of ABS plate layer or increase the thickness of surperficial PC sheet metal layer.
It is bottom that the composite board obtained through injection machine co-extrusion in described step 1) also comprises another PC sheet metal layer, thus improves the quality of the duricrust casing of preparation further.
Hot briquetting in described step 4) is operating as: the hot briquetting in described step 4) is operating as: the cutting blade of composite board step 3) obtained first is preheated to 40-60 DEG C, and then the cutting blade of composite board is put into forming machine, by the cutting blade Four built in boundaries of composite board in the lower mode cavity of forming machine, cover upper cavity again, the temperature of bed die is 40-60 DEG C, the temperature of upper cavity is 430-460 DEG C, then mold is placed in above cutting blade, up to be moved by air cylinder driven bed die and by cutting blade top to mold, mold and bed die coordinate makes cutting blade hot-forming, after cutting blade is shaping, bed die resets, and mold is removed, then is taken out by the ABS/PC duricrust casing after shaping.By above thermoforming process, the cutting blade of composite board is processed into ABS/PC duricrust tank material of the present invention.
When described cutting blade is fixed on forming machine, bed die adopts circulating water, is cooled to 40-60 DEG C.
Adopt manufacture method of the present invention, on the existing basis by the duricrust casing of two-layer plastic material coextrusion mold, attached one deck PC overlay film on the surface of duricrust casing, thus increase the wearability of hard shell trunk surface.Because PC overlay film is flexible material, also can improve hard shell trunk surface shock resistance, and then reach the object extending duricrust casing service life.Meanwhile, PC overlay film is directly attached on the two-layer above co-extrusion glue material of firm coextrusion, and utilize the remaining temperature of the co-extrusion of two-layer above co-extrusion glue material, do not need extra heating, processing technology is simple.
