隨著消費性電子產品、汽機車、醫藥等相關產業的迅速發展，塑膠零件的使用量及比例提昇許多，為了順應飛快發展的塑膠製品產業，並且使塑膠製品開發業者能快速且低成本的搶下訂單，快速模具(Rapid Tooling,RT)的技術隨之應運而生。快速模具主要是應用於小規模塑膠製品產量的製程，其具有修改成本低廉且製模迅速的優點，非常適合各類型塑膠製品的少量、多樣且客製化生產。 With the rapid development of related industries such as consumer electronics, automobile and motorcycle, medicine, etc., the use and proportion of plastic parts have increased a lot, in order to comply with the rapid development of the plastic products industry, and enable plastic product developers to quickly and cost-effectively Ordering, Rapid Tooling (RT) technology came into being.

It has the advantages of low cost modification and rapid mold making, and is very suitable for small, diverse and customized production of various types of plastic products.
既有快速模具的製造方法是將原型樣品(Prototype sample)置入快速模具的模框，並直接注入各種塑膠材料，待塑膠材料硬化後，脫模取出該原型樣品，硬化的塑膠材料即可形成快速模具。此種方法雖可快速製得快速模具，但原型樣品在脫模的過程中，可能會有脫模不易或是原型樣品在脫模時損壞等等問題，倘若原型樣品僅有一個，則需要重新製作，造成成本與時間效益銳減。 The method of manufacturing the rapid mold is to put the prototype sample into the mold frame of the rapid mold and directly inject various plastic materials. After the plastic material is hardened, the prototype sample is taken out and the hardened plastic material is formed. Quick mold. Although this method can quickly produce a rapid mold, the prototype sample may have difficulty in demolding or damage of the prototype sample during demolding during the demolding process. If there is only one prototype sample, it needs to be re Production, resulting in a sharp reduction in cost and time efficiency.
而上述用於製造快速模具的塑膠材料目前是以矽膠(Silicone)為主，由於矽膠在後續製造塑膠製品時，其強度如耐高溫及耐高壓的能力有限， 導致所能生產的塑膠製品件數相對較低，非常容易損壞，且無法應用於例如熱壓發泡等需要高溫高壓製程條件的運用，限制了其工業上的發展。 The above-mentioned plastic materials for manufacturing rapid molds are mainly made of silicone (Silicone), and the strength of the silicone rubber is limited, such as high temperature resistance and high pressure resistance, in the subsequent manufacture of plastic products. The number of plastic products that can be produced is relatively low, which is very easy to damage, and cannot be applied to applications requiring high-temperature and high-pressure process conditions such as hot-press foaming, which limits its industrial development.

6.根據本發明表3熱壓實驗結果證明，單純雙酚A型環氧樹脂在相同測試條件下之壓縮厚度變形量達2.9%，較本發明實施例I添加該改質石墨烯後的耐高溫高壓快速模具僅1.8%的變形量而言，增加了1.1%的壓縮厚度變形量，且目前業界已知的快速模具壓縮厚度變形量甚至高達3%以上，由此足以證實本發明耐高溫高壓快速模具較目前既有快速模具材質，於耐高溫高壓的特性上有顯著進步性。 6.

Compared with the current rapid mold material, the rapid mold has significant progress in high temperature and high pressure resistance.

本發明耐高溫高壓快速模具的製造方法較佳實施例，請一併參考圖1，其步驟包含：將一可塑片20以一原型樣品10為成型治具，利用真空吸塑的方法，將該可塑片20局部成型為具有該原型樣品10輪廓線條的一成型結構21。 A preferred embodiment of the method for manufacturing a high temperature and high pressure rapid mold according to the present invention, please refer to FIG. 1 together, the steps of which include: forming a moldable sheet 20 into a prototype sample 10 by using a vacuum blister method. The pliable sheet 20 is partially formed into a formed structure 21 having the contour lines of the prototype sample 10.
該成型結構21成型於該原型樣品10上時，與該原型樣品10的接觸面會形成一第一成型面211以及對應該第一成型面211之一第二成型面213，再利用一擋板30對應該第一成型面211或該第二成型面213周圍圍繞出一容置空間40，將流動態之一耐高溫高壓塑膠材料50注入該容置空間40中，待該耐高溫高壓塑膠材料50硬化成型後，即可將硬化後該耐高溫高壓塑膠材料50自該容置空 間40取出，即為一耐高溫高壓快速模具60。 When the molding structure 21 is formed on the prototype sample 10, a contact surface with the prototype sample 10 forms a first molding surface 211 and a second molding surface 213 corresponding to the first molding surface 211, and a baffle is used. 30 corresponding to the first molding surface 211 or the second molding surface 213 surrounding an accommodating space 40, a flow dynamic high temperature resistant high pressure plastic material 50 is injected into the accommodating space 40, and the high temperature resistant high pressure plastic material is to be 50 after hardening molding, the high temperature resistant high pressure plastic material 50 can be self-hardened after the hardening The 40 is taken out, which is a high temperature and high pressure rapid mold 60.
上述該原型樣品10較佳是以3D列印、電腦數值控制工具機製程(Computer Numerical Control,CNC)、光硬化樹脂製程、木材雕刻、金屬加工或是陶塑捏製等方式，快速製作出該原型樣品10以利後續翻模，3D列印包含熔融沈積或是熱熔擠製成型(Fused Deposition Modeling,FDM)之技術；利用該可塑片20所形成之該成型結構21具有彈性，稍加擠壓或彎曲不致於損壞或變形，使硬化後的該耐高溫高壓快速模具60更加容易脫模取出。一般來說，該原型樣品10通常僅少量生產，本實施例透過該可塑片20對應該原型樣品10之外型所形成的該成型結構21，若後續製成該耐高溫高壓快速模具60時，該成型結構21因脫模而遭破壞，可利用新的該可塑片20對應該原型樣品10之形狀外型再次製作出該成型結構21，避免既有技術利用珍貴的該原型樣品10翻模時，造成該原型樣品10破壞損失。 Preferably, the prototype sample 10 is rapidly produced by 3D printing, computer numerical control tool (CNC), photo-curing resin process, wood engraving, metal processing or ceramic molding. Sample 10 is used for subsequent overmolding, and 3D printing includes a technique of fused deposition or Fused Deposition Modeling (FDM); the formed structure 21 formed by using the moldable sheet 20 has elasticity and is slightly squeezed. The pressing or bending is not damaged or deformed, so that the hardened high temperature and high pressure rapid mold 60 is more easily released from the mold. Generally, the prototype sample 10 is usually only produced in a small amount. In this embodiment, the molded structure 21 formed by the external shape of the prototype sample 10 is matched by the plastic sheet 20, and if the high temperature and high pressure rapid mold 60 is subsequently formed, The molded structure 21 is broken by demolding, and the new molded piece 20 can be used to reproduce the molded structure 21 corresponding to the shape of the prototype sample 10, so as to avoid the prior art using the precious prototype sample 10 when overmolding , causing damage to the prototype sample 10 damage.
請參考圖2，本發明第二較佳實施例係進一步於第一較佳實施例將流動態之該耐高溫高壓塑膠材料50注入該容置空間40的時候，以貫穿該耐高溫高壓塑膠材料50之形式，埋設一散熱導管70於該耐高溫高壓塑膠材料50內部，當該耐高溫高壓塑膠材料50硬化成型為該耐高溫高壓快速模具60時，該耐高溫高壓快速模具60即可具有散熱的功能，改善以往模具製成後需額外穿孔將散熱裝置設置於其中的繁瑣過程。 Referring to FIG. 2, a second preferred embodiment of the present invention further penetrates the high temperature resistant high pressure plastic material when the high temperature resistant high temperature resistant plastic material 50 is injected into the accommodating space 40 in the first preferred embodiment. In the form of 50, a heat dissipation duct 70 is embedded in the high temperature resistant high pressure plastic material 50. When the high temperature resistant high pressure plastic material 50 is hardened into the high temperature resistant high pressure rapid mold 60, the high temperature resistant high pressure rapid mold 60 can have heat dissipation. The function is to improve the cumbersome process of setting up the heat sink in the past after the mold is made.
該散熱導管70不限定僅為導管的形式，隨該耐高溫高壓快速模具60外型需求而任意調整，以解決現有技術散熱流道加工的煩冗問題，使用者可將任何適用之散熱裝置皆可埋設於該耐高溫高壓塑膠材料50中，由於該散熱導管70係於該耐高溫高壓塑膠材料50為流動態時置入，當該耐高溫高壓塑膠材料50硬化為該耐高溫高壓快速模具60時，該散熱導管70即可固定於該耐高溫高壓快速模具60中，因此，使用者可以依據需求擺設所需型態的該散熱導管70至所 需的位置，或是該散熱導管70可預先彎折形成所需外型再置入，進一步解決現有技術無法於模具中形成複雜外型的該散熱導管70的問題，使該耐高溫高壓快速模具60可以有效且均勻地散熱，解決材料於製造過程中可能產生的收縮問題。 The heat dissipating duct 70 is not limited to the form of a duct, and is arbitrarily adjusted according to the requirements of the high temperature and high pressure rapid mold 60 to solve the troublesome problem of the prior art heat dissipating flow path processing, and the user can apply any applicable heat dissipating device. The heat dissipation conduit 70 can be embedded in the high temperature resistant high pressure plastic material 50, and the high temperature resistant high pressure plastic material 50 is hardened to the high temperature and high pressure rapid mold 60. The heat dissipation duct 70 can be fixed in the high temperature and high pressure rapid mold 60. Therefore, the user can arrange the heat dissipation duct 70 to the desired type according to requirements. The required position, or the heat dissipating duct 70 can be pre-bent to form a desired shape and re-inserted, further solving the problem that the prior art cannot form a complicated shape of the heat dissipating duct 70 in the mold, so that the high temperature and high pressure rapid mold 60 can effectively and uniformly dissipate heat, solving the shrinkage problems that may occur in the manufacturing process of materials.
前述的第一及第二較佳實施例中所述之該耐高溫高壓塑膠材料50包含一雙酚A型環氧樹脂50~98wt%、一金屬微米(μm)粉末1~50wt%及一石墨烯1~5wt%，該雙酚A型環氧樹脂中含一硬化劑0.1~2wt%。 The high temperature resistant high pressure plastic material 50 described in the first and second preferred embodiments comprises 50 to 98 wt% of a bisphenol A type epoxy resin, 1 to 50 wt% of a metal micron (μm) powder, and a graphite. The olefin is 1~5wt%, and the bisphenol A type epoxy resin contains 0.1~2wt% of a hardener.
本發明所謂的耐高溫及耐高壓是指以該耐高溫高壓材料50所製成的該耐高溫高壓快速模具60，處於140℃~160℃的溫度範圍以及40Kg/cm2~60Kg/cm2的壓力範圍下，壓縮厚度變形量小於2%，且因添加該金屬微米粉末及該石墨烯達到高效導熱特性及快速散熱特性。而本案所謂的「壓縮厚度變形量」是以目前業界常見測量模具加工前後變形量的測試方法，在模具加工前先以游標卡尺等測量工具測量模具壁厚，待加工後再以同樣測量工具測量相同位置之模具壁厚，取得加工前後模具壁厚的差值來判斷模具耐高溫高壓的能力，故稱之為「壓縮厚度變形量」。 The so-called high temperature resistance and high pressure resistance of the present invention refers to the high temperature and high pressure rapid mold 60 made of the high temperature resistant high pressure material 50, which is in a temperature range of 140 ° C to 160 ° C and 40 Kg / cm 2 to 60 kg / cm 2 . Under the pressure range, the compressive thickness deformation is less than 2%, and the metal micron powder and the graphene are added to achieve high heat conduction characteristics and rapid heat dissipation characteristics. The so-called "compression thickness deformation" in this case is a common test method for measuring the amount of deformation before and after mold processing in the industry. Before the mold processing, the wall thickness of the mold is measured with a vernier caliper and the like, and the same measurement tool is used to measure the same after processing. The thickness of the mold wall at the position and the difference in the wall thickness of the mold before and after the machining are used to determine the ability of the mold to withstand high temperature and high pressure, so it is called "compression thickness deformation amount".
其中，本發明使用具有較佳機械性能以及較好耐腐蝕性的雙酚A型環氧樹脂，並搭配對雙酚A型環氧樹脂中環氧基反應速率較高的硬化劑雙氰胺，可形成高密度的交聯網絡，增加耐高溫高壓之能力。本發明所使用之該雙酚A型環氧樹脂係屬於單劑型的環氧樹脂，該硬化劑可使該雙酚A型環氧樹脂僅需加熱即可達到硬化的效果，相對於目前既有兩劑型或雙液型的環氧樹脂，當兩劑摻混後會快速反應並且硬化，可操作時間範圍較為短暫且不好保存，導致施作上的困難而言，本發明則可自行調整加熱硬化的時間、溫度，大幅增加操作實施的彈性。 Among them, the present invention uses a bisphenol A type epoxy resin having better mechanical properties and better corrosion resistance, and is matched with a dicyandiamide which has a high rate of reaction with an epoxy group in a bisphenol A type epoxy resin. It can form a high-density cross-linking network and increase the ability to withstand high temperature and high pressure. The bisphenol A type epoxy resin used in the invention belongs to a single-agent epoxy resin, and the hardener can achieve the hardening effect only by heating the bisphenol A type epoxy resin, compared with the existing one. Two- or two-component epoxy resin, when two agents are mixed, will react quickly and harden, the operation time range is short and not easy to store, and the invention can adjust the heating by itself. The time and temperature of hardening greatly increase the flexibility of the operation.
上述該金屬微米粉末包含一鋁粉、一氧化鋁粉(氧化陶瓷粉末)或一氧化鋅粉，該耐高溫高壓快速模具60中添加該金屬微米粉末可使本發明之該 耐高溫高壓快速模具60具有高導熱及結構強化的特性。 The metal micron powder comprises an aluminum powder, an aluminum oxide powder (oxidized ceramic powder) or a zinc oxide powder, and the metal micron powder is added to the high temperature and high pressure rapid mold 60 to enable the present invention. The high temperature resistant high pressure rapid mold 60 has high thermal conductivity and structural strengthening characteristics.
上述該石墨烯較佳是利用一甲基丙烯醯氧基矽烷偶聯劑及一氨基矽烷偶聯劑加以改質而成之一改質石墨烯。其中，改質該石墨烯之一較佳實施例是利用該甲基丙烯醯氧基矽烷偶聯劑8.2wt%以及該氨基矽烷偶聯劑0.9wt%加以改質90.9wt%的石墨烯。 Preferably, the graphene is modified to be a modified graphene by a monomethacryloxy decyl coupling agent and an amino decane coupling agent. Among them, a preferred embodiment of upgrading the graphene is to modify the graphene of 90.9 wt% by using 8.2 wt% of the methacryloxy decyl decane coupling agent and 0.9 wt% of the amino decane coupling agent.
本發明改質該石墨烯的原因是未改質的石墨烯與雙酚A型環氧樹脂極性差異大，混合時結合性不佳會導致石墨烯團聚現象。而利用矽烷偶聯劑改質石墨烯後，帶有官能基的石墨烯表面對環氧樹脂親和性得到改善，進而提高石墨烯分散以及與環氧樹脂結合之能力，使得改質後的該改質石墨烯可直接與該雙酚A型環氧樹脂反應，有助於該石墨烯的分散及與該雙酚A型環氧樹脂的結合，且添加該石墨烯於該耐高溫高壓塑膠材料50中可增加最後該耐高溫高壓快速模具60的散熱特性，使得該耐高溫高壓快速模具60於高溫的環境中可快速的將熱能排出，減少材料結構因為高溫而產生劣解或崩壞。 The reason why the graphene is modified by the present invention is that the unmodified graphene and the bisphenol A type epoxy resin have different polarities, and the poor bonding property during mixing leads to graphene agglomeration. After the graphene is modified by the decane coupling agent, the affinity of the graphene surface with the functional group improves the affinity of the epoxy resin, thereby improving the dispersibility of the graphene and the ability to bond with the epoxy resin, so that the modified after the modification The graphene can directly react with the bisphenol A epoxy resin, contribute to the dispersion of the graphene and the combination with the bisphenol A epoxy resin, and add the graphene to the high temperature resistant high pressure plastic material 50. The heat dissipation characteristic of the last high temperature and high pressure rapid mold 60 can be increased, so that the high temperature and high pressure rapid mold 60 can quickly discharge heat energy in a high temperature environment, thereby reducing the material structure due to high temperature and causing inferior solution or collapse.
