注塑加工模具的使用如今在是生活中越來越常見，很多人對該產(chǎn)品的有關(guān)知識實(shí)際上是知之甚少的，所以要想更好的使用產(chǎn)品就要多了解有關(guān)問題，下面來講個(gè)問題--注塑加工模具的組成包含哪些要素？
The use of injection molding mold is now more and more common in life, a lot of people on the knowledge of the product is actually very little, so in order to better use the product to understand more about the problem, here is a question - injection molding mold composition contains what elements?
注塑加工模具澆注系統(tǒng)。澆注系統(tǒng)是指塑料從射嘴進(jìn)入型腔前的流道部分，包括主流道、冷料穴、分流道和澆口等。澆注系統(tǒng)又稱流道系統(tǒng)，它是將塑料熔體由注射機(jī)噴嘴引向型腔的一組進(jìn)料通道，通常由主流道、分流道、澆口和冷料穴組成。它直接關(guān)系到塑料制品的成型質(zhì)量和生產(chǎn)效率。
Injection molding mold pouring system. Pouring system refers to the plastic from the nozzle into the cavity before the runner part, including the main channel, cold hole, shunting channel and gate. Gating system, also known as runner system, is a set of feed channels that lead plastic melt from the injection machine nozzle to the cavity, usually composed of the main channel, shunting channel, gate and cold hole. It is directly related to the molding quality and production efficiency of plastic products.
注塑加工模具主流道。它是模具中連接注塑機(jī)射嘴至分流道或型腔的一段通道。注塑加工模具冷料穴。它是設(shè)在主流道末端的一個(gè)空穴，用以捕集射嘴端部兩次注射之間所產(chǎn)生的冷料，從而防止分流道或澆口的堵塞。如果冷料一旦混入型腔，則所制制品中容易產(chǎn)生內(nèi)應(yīng)力。
Injection molding mold main channel. It is a channel connecting the injection nozzle of the injection molding machine to the shunting channel or cavity. Injection molding mold cold hole. It is a hole at the end of the main passage to trap the cold material produced between two injections at the nozzle end, thus preventing the blockage of the shunt or gate. If the cold material once mixed into the cavity, it is easy to produce internal stress in the products.
注塑加工模具分流道。它是多槽模中連接主流道和各個(gè)型腔的通道。為使熔料以等速度充滿各型腔，分流道在塑模上的排列應(yīng)成對稱和等距離分布。
Injection molding mold shunting channel. It is the channel connecting the main channel and each cavity in the multi-groove die. In order to fill the cavity with molten material at the same speed, the distribution of shunting channels on the mould should be symmetrical and equidistant.
此外，對材料也是有一定的要求的，比如說：模具在工作中由于填充和流動的塑料承受較大的壓縮應(yīng)力和摩擦，要求模具保持其形狀的精度和尺寸精度的穩(wěn)定性，以確保模具具有足夠的使用壽命。模具耐磨性取決于鋼的化學(xué)成分和熱處理硬度，因此提高模具的硬度有利于提高其耐磨性。
In addition, there are certain requirements for the material, such as: the mold in the work due to the filling and flow of plastic under large compressive stress and friction, requires the mold to maintain the stability of its shape accuracy and dimensional accuracy, to ensure that the mold has enough service life. The wear resistance of die depends on the chemical composition of steel and the hardness of heat treatment, so improving the hardness of die is beneficial to improve its wear resistance.
濟(jì)南注塑加工人員提醒：注塑模具部件的形狀往往比較復(fù)雜，淬火后難以加工，應(yīng)盡量使用良好的熱穩(wěn)定性，當(dāng)模具加工熱處理后由于線膨脹系數(shù)小，熱處理變形小，由于尺寸變化率小，金相組織和模具尺寸穩(wěn)定，可以減少或不再加工的溫差，可以確保模具尺寸精度和表面粗糙度的要求。
Ji 'nan injection molding personnel remind: The shapes of the injection mold parts tend to be complex, difficult to processing after quenching, should try to use good thermal stability, when the mould processing due to the small linear expansion coefficient after heat treatment, heat treatment deformation is small, due to their small size change rate, microstructure and mould size stability, can reduce the temperature difference or no processing, to ensure that mold size accuracy and surface roughness requirements.
