The gating system is an important part of mold processing. The gating system is to fill the injection mold cavity evenly and quickly with melted material, forming a regular shape plastic part. It is composed of sprue, distributor, gate and cold hole. Each part has its own role to complete the whole process of pouring together. The role of each part is introduced one by one in Shandong mold.
1. Sprue: a section of channel connecting the nozzle to the mold to separate the melt is called the main channel. It can effectively transfer pressure, prevent melting material from solidifying too fast, and evenly distribute pressure into other channels.
2. Shunt channel: the flow channel connecting each groove after being separated from the main channel. In order to balance the pressure distribution between the flow channels, the distributary channel is generally symmetrical distribution. The layout of natural balance is used to transport the molten materials to the gate, which can make the filling process of materials uniform and prevent the appearance of unqualified products.
3. Gate: after filling the cavity with material, the gate is cooled quickly to prevent the melt from flowing backward. The gate is a small part of the whole runner system, but it has a great influence on the molding of plastic parts. The design of gate directly affects the quality of plastic parts, so the appropriate gate should be designed according to the shape and structure of plastic parts.
4.冷料井。储存冷料的作用。过滤掉冷却了的融料, 并使好的熔料能顺利充满型腔的一个环节， 防止不合格的冷料进入型腔对塑件产生不良影响或堵塞浇口，以免造成产品外观不良，影响塑件质量。
4. Cold material well. The function of cold material storage. Filter out the cooled melt material and make the good melt fill the mold cavity smoothly, so as to prevent the unqualified cold material from entering the mold cavity, causing adverse effect on the plastic parts or blocking the gate, so as to avoid the appearance defect of the product and affect the quality of the plastic part.
According to the appearance structure and product performance of plastic parts, the design of gating system should be adjusted to achieve high quality and qualified injection mold.
The above is about the mold processing gating system design and function of the introduction, I hope to help you, if you want to know more about the content, please click the website: Shandong mold http://www.jnhjgs.cn 。
