All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the description of the invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. Furthermore, the terms "first," "second," and the like in the description and in the claims, as well as in the drawings, are used for distinguishing between different objects and not necessarily for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Referring to fig. 1-5, a housing forming system 20 for forming a housing 30 of a product is provided. The housing forming system 20 includes an external heating device 40 and a hot press mold 50. The mold heating device 40 is configured to heat a plurality of predetermined portions of a glass fiber plate 32 to respective predetermined temperatures, and the predetermined temperatures corresponding to the plurality of predetermined portions may be different. If the position of the edge of the glass fiber plate 32 requiring deformation is heated to 130 degrees, the position of the plane of the glass fiber plate 32 not requiring deformation is heated to 80 degrees. The hot pressing mold 50 is used for hot pressing the glass fiber plate 32 heated outside the mold into a predetermined shape, and performing injection molding during the hot pressing so that the edge of the hot pressed glass fiber plate 32 is combined with the plastic 70 to form the housing 30 with a predetermined shape.
The hot press mold 50 includes a cavity 52 and a core 54. The cavity insert 52 is provided with a plurality of first heating members 56 and a plurality of first temperature sensing members (not shown). The first temperature sensing elements sense temperatures of a plurality of portions of the cavity insert 52. The first heating member 56 is an oil pipe. The oil pipes are communicated with the oil cylinder, and heat a plurality of portions of the female mold core 52 to respective corresponding preset temperatures, so that the portions of the glass fiber plate 32 in the hot-pressing mold 50 are kept within corresponding preset temperature ranges, and the glass fiber plate 32 placed on the male mold core 54 is hot-pressed to form a three-dimensional curved surface on the glass fiber plate 32.
The core insert 54 is formed with a through hole 58, a fixing block 60 is fixed in the through hole 58, and a second heating element (not shown) and a second temperature sensing element (not shown) are disposed in the fixing block 60. The second heating member is used to heat the fixing block 60 to a prescribed temperature. The second temperature sensing member is used for sensing the temperature of the fixed block 60. A molding insert 62 is fixed to an end of the fixing block 60 opposite to the cavity 52, and the molding insert 62 extends out of the core 54 and is used for forming a mark 68 on the glass fiber plate 32 when the glass fiber plate 32 between the core 54 and the cavity 52 is hot-pressed when heated to a predetermined temperature. The mark 68 is a trademark or a product serial number, etc. In one embodiment, a plurality of threaded holes 64 are formed on the opposite sides of the fixing block 60 and the core insert 54 from the cavity insert 52, and a plurality of screws are screwed into the threaded holes 64 of the fixing block 60 and the core insert 54 to fix the fixing block 60 in the through hole 58. The molding insert 62 is fixed to the fixing block 60 by a positioning pin.
The core insert 54 further forms a casting system 66 for injection molding when the hot pressing mold 50 performs hot pressing on the glass fiber plate 32, so that the edge of the hot pressed glass fiber plate 32 is combined with the plastic 70 to form the housing 30 with a preset shape.
Fig. 6 is a flowchart illustrating a method for forming a housing 30 according to the present invention. The method of forming the housing 30 includes the following steps.
Step S401: predetermined portions of a glass fiber sheet 32 are heated to respective predetermined temperatures by an external mold heating device 40. The preset temperatures corresponding to the preset parts are different.
Step S402: the glass fiber sheet 32 heated by the mold external heating device 40 is placed in a core insert 54 of a hot press mold 50.
Step S403: the cavity 52 of the hot pressing mold 50 is closed to the core 54, so that the glass fiber sheet 32 is hot pressed into a predetermined shape. The preset shape is a three-dimensional curved surface. In one embodiment, when the cavity 52 is clamped on the core 54 and the glass fiber sheet 32 is hot pressed, a mark 68 is formed on the glass fiber sheet 32, and the mark 68 is a trademark or a product serial number.
Step S404: the injection molding is performed by an injection molding system on the hot pressing mold 50 during the hot pressing, so that the edges of the glass fiber plate 32 subjected to the hot pressing are combined with the plastic 70 to form the housing 30 with a predetermined shape.
The housing forming system 20 and the housing 30 forming method form the housing 30 by hot-pressing the glass fiber plate 32 and performing injection molding during the hot-pressing so that the edge of the glass fiber plate 32 is combined with the plastic 70, and since the glass fiber plate 32 has high strength and low cost, and the surface thereof can be directly used as the appearance surface of a product, a post-processing paint spraying process is not required, the formed housing 30 also has the advantages of high strength, environmental protection, low cost and the like.
It will be appreciated by those skilled in the art that the above embodiments are illustrative only and not intended to be limiting, and that suitable modifications and variations to the above embodiments are within the scope of the disclosure provided that the invention is not limited thereto.
