Description
本發明是有關於一種產品的模具及其製造方法，特別是指一種製造具傾角之纖維強化外殼的熱壓模具及其製造方法。The present invention relates to a mold for a product and a method of manufacturing the same, and more particularly to a hot press mold for manufacturing a fiber reinforced outer shell having an inclined angle and a method of manufacturing the same.
參閱圖1，現有製造碳纖維外殼100的熱壓模具1包括相配合的一下模11與一上模12，及一介於該下模11與該上模12之間的分模面13。其中，該下模11具有一位於該分模面13下方的模穴111，該上模12具以一對應該模穴111的模仁121。Referring to Fig. 1, a conventional hot press mold 1 for manufacturing a carbon fiber outer casing 100 includes a mating lower mold 11 and an upper mold 12, and a parting surface 13 interposed between the lower mold 11 and the upper mold 12. The lower mold 11 has a cavity 111 below the parting surface 13, and the upper mold 12 has a pair of mold cores 121 which are cavities 111.
實際應用時，是將多數碳纖維預浸布14層疊於該模穴111中，再配合該模仁121熱壓所述碳纖維預浸布14而製成該碳纖維外殼100，其中，該碳纖維外殼100包括一概呈平板狀的本體101，及一環繞該本體101周緣的圍繞壁102。In practical application, a plurality of carbon fiber prepreg 14 is laminated in the cavity 111, and the carbon fiber prepreg 14 is hot pressed with the mold core 121 to form the carbon fiber outer casing 100. The carbon fiber outer casing 100 includes the carbon fiber outer casing 100. A substantially planar body 101 and a surrounding wall 102 surrounding the periphery of the body 101.
參閱圖2，隨著人們求新求變的需求，現有碳纖維外殼100除了包括該本體101與該圍繞壁102外，大多會於該圍繞壁102相反於該本體101之一側上形成有傾角103，除具美觀效果外，還能便於使用者拿取。Referring to FIG. 2, the existing carbon fiber outer casing 100, in addition to the body 101 and the surrounding wall 102, is formed with an inclination 103 on the side of the surrounding wall 102 opposite to the body 101. In addition to the aesthetic effect, it is also convenient for the user to take.
利用該熱壓模具1製造形成有傾角103之碳纖維外殼100時，形成於該圍繞壁102上的傾角103會在下模11的模穴111上形成嵌角(undercut)112，不但會影響碳纖維外殼100的脫模作業，而且嵌角112還會阻礙熱壓壓力的傳遞，導致傾角103處的結構較為鬆散脆弱而容易發生損壞。When the carbon fiber outer casing 100 having the inclination angle 103 is formed by the hot press die 1, the inclination 103 formed on the surrounding wall 102 forms an undercut 112 on the cavity 111 of the lower mold 11, which affects not only the carbon fiber outer casing 100. The demolding operation, and the bezel 112 also hinders the transfer of the hot pressing pressure, resulting in a structure that is relatively loose and fragile at the dip angle 103 and susceptible to damage.
為避免上述缺點，現有形成於該圍繞壁102上的傾角103，大多是額外再利用電腦數值控制(Computer Numerical Control,CNC)的加工方式，以於該圍繞壁102上切削成型出傾角103。如此雖然能避免上述缺點，但是，額外加工無疑是增加額外的生產成本與加工時間，而所切削下來的材料也是一種原料上的浪費。In order to avoid the above disadvantages, the existing inclination angle 103 formed on the surrounding wall 102 is mostly processed by a computer numerical control (CNC) to form a dip angle 103 on the surrounding wall 102. Although the above disadvantages can be avoided, the additional processing is undoubtedly an increase in additional production cost and processing time, and the material to be cut is also a waste of raw materials.
因此，本發明之目的，即在提供一種能減少成本與加工時間，並避免原料浪費之製造具傾角之纖維強化外殼的熱壓模具。Accordingly, it is an object of the present invention to provide a hot press mold for producing a fiber reinforced outer casing having an inclined angle which can reduce cost and processing time and avoid waste of raw materials.
