今天小编为大家带来的一个相关知识便是怎么来确定注塑模具浇口截面的大小，希望能够让您更加了解注塑模具，以便以后更好的使用工作。

　　Today xiaobian for you to bring a related knowledge is how to determine the size of the injection mold gate section, I hope to let you know more about the injection mold, so that the future better use of work.

　　按照山东模具制造厂家的常规，浇口的截面尺寸要小，不能大。在确定浇口尺寸时，应先变小，然后在试模过程中，根据型腔的填充情况进行修正，特别是对于一模有多个型腔的模具，通过修正，每一个同时可以均匀地填充型腔。

　　According to the general practice of Shandong mold manufacturers, the section size of the gate should be small, not large. In the determination of gate size, should be smaller first, and then in the mold test process, according to the cavity filling situation for correction, especially for a mold with multiple cavities, through correction, each can fill the cavity evenly at the same time.

　　为防止应力引起变形，一般浇口要薄；为了防止缩痕，浇口要厚；如果充填不足，则要宽，在模具允许范围内，浇口和流道的长度要短。曲折少为好；影响注塑件外观的浇口尽量小：对于质量大、形状大、收缩率大的产品，浇口尽量大。

　　In order to prevent deformation caused by stress, the gate should be generally thin. In order to prevent shrinkage marks, the gate should be thick; If the filling is insufficient, it should be wide and the length of the gate and runner should be short as the mold allows. Less twists and turns is better; The gate that affects the appearance of injection parts should be as small as possible: for products with large quality, large shape and large shrinkage rate, the gate should be as large as possible.

　　小浇口可以增加熔体的流速，增加熔体的摩擦力，提高熔体的温度。结果熔体的粘度降低，有利于充模。但由于小浇口阻力大，注射压力损失大，不利于熔体的充填，尤其是远射部分的薄结构。有些制品的浇口不宜过小，如一些厚壁制品，在注射过程中要进行两次以上的附加压力，才能满足塑料制品的要求。

　　The small gate can increase the flow rate of melt, increase the friction force of melt and raise the temperature of melt. Results The viscosity of melt decreased, which was beneficial to mold filling. However, because of the large resistance of the small gate and the large loss of injection pressure, it is not conducive to melt filling, especially for the thin structure of the far-shot part. Some products of the gate should not be too small, such as some thick wall products, in the process of injection to carry out more than two additional pressure, to meet the requirements of plastic products.

　　总之，浇口的形式和截面尺寸会影响注塑件的变形，不同形状的注塑件应采用不同的浇口形状和断面尺寸。所以在使用时一定要多加注意吧！

　　In short, the form and section size of the gate will affect the deformation of the injection molded parts, and different shapes of the injection molded parts should use different gate shape and section size. So in use must pay more attention to it!
