快速模具技術(shù)是在快速成型技術(shù)的基礎(chǔ)上發(fā)展的一種新型模具制造技術(shù)，不過(guò)還需要不斷的完善和研究。下面山東快速成型廠(chǎng)家來(lái)講講快速模具制造方法有哪兩種.

Rapid tooling technology is a new mold manufacturing technology developed on the basis of rapid prototyping technology, but it still needs to be improved and studied continuously. Next, Shandong rapid prototyping manufacturer will talk about the two methods of rapid tooling manufacturing

快速模具制造方法有兩種:

There are two methods of rapid tooling manufacturing:

一種為間接制模，間接制模是以快速原型為模型采用某種工藝制造模具;

One is indirect mold making, which uses rapid prototyping as a model and adopts a certain process to manufacture the mold;

另一種為直接制模，直接制模是在快速原型制造設(shè)備上直接制造模具，即根據(jù)制品形狀設(shè)計(jì)了模具的三維實(shí)體模型或?qū)⒘慵Ｐ娃D(zhuǎn)換為型腔模型，選擇專(zhuān)用材料，利用快速原型技術(shù)制造模具。

The other is direct mold making. Direct mold making is to directly manufacture the mold on the rapid prototyping manufacturing equipment, that is, design the 3D solid model of the mold according to the shape of the product or convert the part model into the cavity model, select special materials, and use the rapid prototyping technology to manufacture the mold.

在快速制模技術(shù)中，制造出尺寸精度比較高的快速原型是前提，但大部分快速成型得到的原型因材質(zhì)和成型工藝的限制，一般不采取直接制模的方法。用快速原型制母模，澆注蠟、硅橡膠、環(huán)氧樹(shù)脂、聚氨脂等軟材料，可構(gòu)成軟模具。

In rapid prototyping technology, it is the premise to produce rapid prototyping with high dimensional accuracy, but most of the prototypes obtained by rapid prototyping are not directly molded due to the limitations of materials and molding technology. The soft mold can be formed by casting wax, silicone rubber, epoxy resin, polyurethane and other soft materials with rapid prototyping master mold.

硅橡膠制模制造工藝是一種比較普及的快速模具制造方法。由于硅橡膠模具具有良好的柔性和彈性，能夠制作結(jié)構(gòu)復(fù)雜、花紋精細(xì)、模斜度甚具有倒拔模斜度以及具有深凹槽類(lèi)的零件，制作周期短，制件質(zhì)量高，因而備受關(guān)注。由于零件的形狀尺寸不同，對(duì)硅橡膠模具的強(qiáng)度大小要求也不一樣，因而制模方法也有所不同。

Silicone rubber mold manufacturing process is a popular rapid mold manufacturing method. Due to the good flexibility and elasticity of silicone rubber mold, it can make parts with complex structure, fine pattern, mold slope, even reverse draft angle and deep groove, short manufacturing cycle and high product quality, so it has attracted much attention. Due to the different shapes and sizes of parts, the requirements for the strength of silicone rubber molds are also different, so the molding methods are also different.

電弧噴涂快速制模以原型為樣模，將熔點(diǎn)的熔化金屬充分霧化后以一定的速度噴射到樣模表面，形成模具型腔表面，背襯充填復(fù)合材料，用填充鋁的環(huán)氧樹(shù)脂或硅橡膠支撐，將殼與原型分離，得到精密的模具，并加入澆注系統(tǒng)和冷卻系統(tǒng)等，連同模架構(gòu)成注射模具。

The arc spraying rapid mold making takes the prototype as the sample mold. The molten metal at the melting point is fully atomized and sprayed onto the sample mold surface at a certain speed to form the mold cavity surface. The backing is filled with composite materials. The shell is supported by aluminum filled epoxy resin or silicone rubber. The shell is separated from the prototype to obtain a precise mold, and the pouring system and cooling system are added to form the injection mold together with the mold base.

樹(shù)脂型復(fù)合模具制模是將液態(tài)的環(huán)氧樹(shù)脂與有機(jī)或無(wú)機(jī)材料復(fù)合作為基體材料，然后以原型為基準(zhǔn)澆注模具。工藝過(guò)程為:制作原型-表面處理-表面設(shè)計(jì)、制作模框-選擇、設(shè)計(jì)分型面-在原型表面、分型面刷脫模劑，膠衣樹(shù)脂-澆注凹模。

Resin composite mold manufacturing is to composite liquid epoxy resin with organic or inorganic materials as the matrix material, and then pour the mold based on the prototype. The technological process is: making prototype - surface treatment - surface design, making mold frame - selection, design parting surface - brushing release agent on the prototype surface and parting surface, gel coat resin - casting concave mold.

硅膠-陶瓷型橡膠模制模其通過(guò)涂層轉(zhuǎn)移獲得精密陶瓷型，澆鑄鑄鋁或黑色金屬。快速精密鑄造模具采用快速精密鑄造的方式得到快速模具有許多方法。它利用立體光刻工藝獲得零件膜具的半中空原型，然后在原型的外表面掛漿，得到有一定厚度和粒度的陶瓷層，它緊緊地包裹在原型的外面，再放入高溫爐中燒掉半中空原型。

Silicone - ceramic rubber mold. It can obtain precise ceramic mold through coating transfer and cast aluminum or ferrous metal. There are many ways to obtain rapid tooling by rapid precision casting. It uses the stereo lithography process to obtain the semi-hollow prototype of the part film, and then hangs slurry on the outer surface of the prototype to obtain a ceramic layer with a certain thickness and size, which is tightly wrapped around the outside of the prototype, and then put it into a high-temperature furnace to burn the semi-hollow prototype.

該方法的優(yōu)點(diǎn)是用原型代替原來(lái)精密鑄造中的蠟型，大大提高鑄造原型的精度，大大加快制造速度。您對(duì)此有怎樣的問(wèn)題或需求就來(lái)我們網(wǎng)站http://m.tescen.com咨詢(xún)吧！

The advantage of this method is that the wax mold in the original precision casting is replaced by the prototype, which greatly improves the precision of the casting prototype and greatly accelerates the manufacturing speed.
