使用热流道模具是降低成本的好方法。不仅减少了环境污染，而且缩短了注塑制品的生产周期，提高了工作效率。同时还可以提高注塑产品的质量，达到注塑产品质量的一致性。今天我们就来说说注塑模具热流道的使用方法以及故障点的方法。
Using hot runner mold is a good way to reduce cost. It not only reduces environmental pollution, but also shortens the production cycle of injection molding products and improves work efficiency. At the same time, it can also improve the quality of injection products and achieve the consistency of injection product quality. Today, let's talk about the use of hot runner of injection mold and the solutions to the fault points.
热流道浇注系统主要可分为两类：一类是带有歧管和分水口的热流道浇注系统；另一种是没有歧管和主流道喷嘴的热流道浇注系统。热流道浇注系统的结构主要包括：主流道喷嘴、分流板、分流道、加热和测温部件、安装和紧固部件，（个别热流道还必须有：阀针、气缸、隔热帽、密封环等）组成。
Hot runner gating system can be divided into two types: one is hot runner gating system with manifold and water outlet; The other is a hot runner gating system without manifold and sprue nozzle. The structure of hot runner gating system mainly includes: main runner nozzle, splitter plate, splitter, heating and temperature measuring parts, installation and fastening parts (individual hot runner must also have: valve needle, cylinder, heat insulation cap, sealing ring, etc.).
1、使用前必须确认模具上热流道承口内加热线和感温线的排列顺序是否符合公司《注塑模具制造规范》的要求。
1. Before use, it is necessary to confirm whether the arrangement order of hot wires and temperature sensing wires in the hot runner bell mouth on the mold meets the requirements of the company's injection mold manufacturing specification.
2、模具上热流道插座内的发热丝和感温丝的顺序也必须与温控箱的顺序和温控箱的连接线一致，以防感温电线被烧坏的顺序不一致。
2. The sequence of heating wires and temperature sensing wires in the hot runner socket on the mold must also be consistent with the sequence of the temperature control box and the connecting wires of the temperature control box, so as to prevent the sequence of temperature sensing wires from being burned out.
3、阀针式热流道还必须连接模具上控制阀针动作的电磁阀和气缸上的进出气管。
3. The valve needle hot runner must also be connected with the solenoid valve on the die to control the action of the valve needle and the air inlet and outlet pipe on the cylinder.
4、热流道加热时，必须每次打开温控箱上的加热开关一段，待温度开始升高时再开启下一段。不要一次打开它。
4. When heating the hot runner, the heating switch on the temperature control box must be turned on one section at a time, and the next section can be turned on when the temperature begins to rise. Don't open it all at once.
5、个别热流道分水口处带有水路密封圈的模具，必须在加热热流道时开启模具冷却系统。防止分喷嘴上的加热圈在高温下烧坏水路密封圈。
5. For molds with water seal ring at the water outlet of individual hot runner, the mold cooling system must be started when heating the hot runner. Prevent the heating ring on the sub nozzle from burning out the water seal ring under high temperature.
6、如果热嘴没有出胶，不要随意提高温控箱内设定的温度或用枪烤嘴。应检查螺杆温度是否到位，螺杆喷嘴是否堵塞。（如果是阀针热流道，还需要检查电磁阀是否正常工作，气缸是否通风等）
6. If there is no glue from the hot nozzle, do not arbitrarily increase the temperature set in the temperature control box or bake the nozzle with a gun. First, check whether the screw temperature is in place and whether the screw nozzle is blocked. (in case of hot runner of valve needle, check whether the solenoid valve works normally and whether the cylinder is ventilated, etc.)
7、
济南注塑模具厂家提醒您在热流道模具生产过程中不要清洗定模分型面（开嘴热流道）。防止热流道内溶胶因受热过大而分解爆裂，溶胶喷出烫伤操作人员。
7. Jinan injection mold manufacturer reminds you not to clean the parting surface of the fixed mold (open nozzle hot runner) during the production of hot runner mold. Prevent the sol in the hot runner from decomposing and bursting due to excessive heating, and scald the operator due to sol spray.
