Abstract
The invention discloses a preparation method of an ABS/PC hard shell box. The preparation method comprises following steps: 1) a composite sheet material with more than two layers is obtained by co-extrusion of an injection molding machine; 2) at the end of the co-extrusion die head of the injection molding machine, the surface of a PC sheet material layer is covered by another PC overlaying film; 3) after covering, the composite sheet material is cut into pieces; and 4) the pieces of the composite sheet material are subjected to thermal forming so as to obtain the ABS/PC hard shell box. Existing hard shell boxes are prepared by two-layer plastic cement material through co-extrusion molding. According to the preparation method, the surface of existing hard shell box is covered with the layer of PC overlaying film, so that wear resistance of the surface of the hard shell box is increased. The PC overlaying film is of a flexible structure, surface impact resistance of the hard shell box is increased, so that service life of the hard shell box is prolonged.
Description
Technical field
The present invention relates to the case and bag field, relate in particular to a kind of manufacture method of ABS/PC duricrust casing.
Background technology
Current luggage case material used on the market is generally all nylon material or plastic material, comprises PP, ABS, PC etc.Wherein, the luggage case of being made by nylon material is referred to as commercial case, and the material of this casing is lighter, but cracky.In addition, by the luggage case general designation hard shell trunk that plastic material is made, 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 customer requirements, wearability and impact resistance are poor, causes casing short service life.
Summary of the invention
In order to overcome above shortcoming, the purpose of this invention is to provide a kind of duricrust casing wearability and impact resistance prepared 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 the injection machine co-extrusion, obtain the composite board more than two-layer, wherein one deck is the ABS sheet metal layer, and one deck PC sheet metal layer is superficial layer at least;
2) laminating: 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 fitting is sent into extruding laminating between two compression rollers;
3) cutting: will be through step 2) composite board after laminating cuts in flakes by case and bag housing size, obtains the sheet that cuts of composite board;
4) hot briquetting: the sheet that cuts of the composite board that step 3) is obtained first preheats to 40-60 ℃, and then the sheet that cuts of composite board is put into to forming machine, and sheet four limits that cut of composite board are fixed in the lower mode cavity of forming machine, cover again upper cavity, then by the air cylinder driven bed die, up move and will cut the sheet top to mold, mold and bed die coordinate makes to cut the sheet hot briquetting, will cut the sheet taking-up and obtain 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 sheet metal layer co-extrusion at the coextruding die head end, due to the close coextruding die head end in the position of laminating, so the composite board surface formed by PC sheet metal layer and ABS sheet metal layer co-extrusion also remains with higher co-extrusion temperature, another PC overlay film operates without extra heating with the laminating of the composite board formed by PC sheet metal layer and ABS sheet metal layer co-extrusion like this, simplify processing technology, improved working (machining) efficiency.
The present invention adopts above manufacture method, has attached one deck PC overlay film in the two-layer hard shell trunk surface of tradition, thereby increases the wearability of hard shell trunk surface.Because the PC overlay film is flexible material, also can improve hard shell trunk surface shock resistance, and then reach the prolongation duricrust casing purpose in service life.
In the present invention, because the hardness of ABS sheet metal layer is greater than surperficial PC sheet metal layer, when the client needs the larger duricrust casing of hardness, can suitably increase the thickness of ABS sheet metal layer, when the client needs the less duricrust casing of hardness, can suitably reduce the thickness of ABS sheet metal layer or increase the thickness of surperficial PC sheet metal layer.
The composite board obtained through the injection machine co-extrusion in described step 1) also comprises that another PC sheet metal layer is bottom, thereby further improves the quality of the duricrust casing of preparation.
Hot briquetting in described step 4) is operating as: the hot briquetting in described step 4) is operating as: the sheet that cuts of the composite board that step 3) is obtained first preheats to 40-60 ℃, and then the sheet that cuts of composite board is put into to forming machine, sheet four limits that cut of composite board are fixed in the lower mode cavity of forming machine, cover again upper cavity, the temperature of bed die is 40-60 ℃, the temperature of upper cavity is 430-460 ℃, then mold is placed in and cuts the sheet top, by the air cylinder driven bed die, up move and will cut the sheet top to mold, it is hot-forming that mold and bed die cooperation make to cut sheet, after cutting the sheet moulding, bed die resets, and mold is removed, then the ABS/PC duricrust casing after moulding is taken out.By above thermoforming process, the sheet that cuts of composite board is processed into to ABS/PC duricrust tank material of the present invention.
Described when cutting sheet and being fixed on forming machine, bed die adopts circulating water, is cooled to 40-60 ℃.
Adopt manufacture method of the present invention, on the basis of existing duricrust casing by two-layer plastic material coextrusion mold, on the surface of duricrust casing, attached one deck PC overlay film, thereby increase the wearability of hard shell trunk surface.Because the PC overlay film is flexible material, also can improve hard shell trunk surface shock resistance, and then reach the prolongation duricrust casing purpose in service life.Simultaneously, the PC overlay film directly is attached on the two-layer above co-extrusion glue material of firm coextrusion, utilizes the remaining temperature of co-extrusion of two-layer above co-extrusion glue material, does not need extra heating, and processing technology is simple.
