[specific embodiment]
Please refer to shown in Figure 1A to Fig. 3 B, the present invention is a kind of injection molding forming method, and it can be applied to two or more raw material integrated injection molding.
One of embodiment of the present invention notebook computer casing 10, because notebook computer casing body 11 is plastic materials, and the sealant 12 that is formed on the notebook computer casing body 11 is elastomeric materials, need be with two kinds of different materials integrated injection moldings, and main preparation method is as follows:
(1) at first provides an injection machine that is equipped with two injection moulding apparatus (being injection molding material pipe A and B) and turntable C, wherein first injection moulding apparatus (injection molding material pipe A) is used for the injection moulding plastic material, and second injection moulding apparatus (injection molding material pipe B) is used for the injection molded elastomer raw material.
(2) provide a retable glue injection mold 20, it is divided into master mold 21 and male model 22, this retable glue injection mold 20 is mounted on the turntable C of injection machine, and its master mold 21 is mounted to first injection molding material pipe A below, male model 22 is positioned at master mold 21 belows, and formed 23, the first injection molding material pipes of mold cavity A between male model 22 and the master mold 21 and can in this mold cavity 23, inject plastic material.
(3) provide one group of rubber injection mold mould 30, it also has master mold 31 and male model 32, and also be mounted on the turntable C of injection machine, and its master mold 31 is mounted to second injection molding material pipe B below, male model 32 is positioned at master mold 31 belows, and formed 33, the second injection molding material pipes of mold cavity B between male model 32 and the master mold 31 and can in this mold cavity 33, inject rubber raw materials.
After above-mentioned steps finished, just also finished the work that mould sets up, mainly have two group moulds 20 and 30, two injection molding material pipe A, Bs and a turntable C on the injection machine this moment, then can carry out following step:
(4) carry out the injection mo(u)lding first time, utilize first injection molding material pipe A in the die cavity 23 of plastic injection mold 20, to inject plastic material, just form the plastic cement body 11 of notebook computer casing, i.e. semi-finished product.Detailed process is: first injection molding material pipe A will make its nozzle withstand the feeding mouth of plastic injection mold 20 by hydraulic-driven, again with the plastic material injection moulding in the injection molding material pipe (raw material type, number and time pressure in the injection molding material pipe can change with the size and the customer requirement of product) to mould, nozzle with first injection molding material pipe A separates with mould 20 feeding mouths then, expiration to be cooled, form the plastic cement body, but just die sinking this moment.
(5) turntable rotates 180 degree, the male model 22 of plastic injection mold 20 will be subjected to its traction together with the male model 32 of the semi-finished product on it 11 and rubber injection mold mould 30 and rotate and switch, but the position of the master mold position of two injection molds and two injection molding material pipe A and B then all can not change.Result after the mould transposing is: the male model 22 that is attached with semi-finished product 11 is the belows that are positioned at master mold 31 and second injection molding material pipe B of rubber injection mold mould 30, and the male model 32 of former rubber injection mold mould 30 is the belows that are positioned at master mold 21 and first injection molding material pipe A of former plastic injection mold 20.
(6) carry out the injection mo(u)lding second time, utilize second injection molding material pipe B in the mold cavity at above-mentioned semi-finished product 11 places, to inject rubber raw materials, thereby on the plastic cement body of notebook computer casing, form a rubber sealant 12, it is finished product, this notebook computer casing is the structure that is integral type, and this combination claims many material combinations again.Similar because of the operating principle of the injection mo(u)lding second time to the operating principle of injection mo(u)lding for the first time, just no longer be described in detail to this herein.With also having that this action is carried out simultaneously, first injection molding material pipe A also injects plastic material in the master mold 21 formed vacant fully die cavities of the male model 32 of former rubber injection mold mould 30 and former plastic injection mold 20, from and form the plastic cement body (being semi-finished product) of a notebook computer casing, promptly finished injection mo(u)lding for the first time.
(7) after injection mo(u)lding is for the second time finished, carry out die sinking, the finished product that will form in the injection mo(u)lding second time by the thimble on the injection machine (not shown) ejects, and relends and helps manipulator that it is taken out.
In the process that above-mentioned steps (6) is carried out, not only can form a finished product (carrying out the injection mo(u)lding second time therein in the mold cavity forms), also can form another semi-finished product (carrying out the injection mo(u)lding first time in another mold cavity forms), take out finished product then, repeat the action and the step (6) of the mould transposing of above-mentioned steps (5) afterwards again, these semi-finished product will carry out the injection mo(u)lding second time in corresponding die cavity, then carrying out injection mo(u)lding for the first time in another die cavity.The continuous production that so goes round and begins again, not only can significantly improve the production efficiency and the product yield of notebook computer casing, and because the rubber layer and the plastic layer of notebook computer casing are the structures that has adopted integral type, it is safe in utilization stable, and the normal service life of having guaranteed computer.
Injection molding forming method of the present invention not only can be applied on the notebook computer, and other need be with the integrated occasion of two or more raw materials can also to be applied to phone housing etc.Because the injection moulding apparatus of two kinds of different materials of injection moulding is assembled one, two kinds of different materials of injection moulding are simultaneously not only saved equipment occupation space, and can be enhanced productivity.
