使用（yòng）熱流道模具是降低成本的好方法。不僅減少了環境（jìng）汙染，而且縮短了注塑製品的生產周期，提高了工作效率。同時還可以提高注塑產品的質量，達到注塑（sù）產品質量的一致性（xìng）。今天我們就來說說注塑模具熱流道的使用方法以及故障點的方法。
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.
熱流道澆注係統主要可分為兩類（lèi）：一類是帶有（yǒu）歧管（guǎn）和分水口的熱（rè）流道澆注係統；另一種是沒有歧管（guǎn）和主流道噴嘴的熱流道澆注係統。熱流道澆注係統的結構主要（yào）包括：主流（liú）道噴嘴、分流板、分流道、加熱和測溫部件、安裝和緊固部件（jiàn），（個別（bié）熱流道還（hái）必須有（yǒu）：閥針、氣缸、隔（gé）熱帽、密封環（huán）等）組成（chéng）。
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（shǐ）用前必須確認模具上熱流道承口內加熱線（xiàn）和感溫線的排列順序是否符合公司《注（zhù）塑模具製造規範》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（jù）上熱（rè）流道插座內的發熱絲和感溫絲（sī）的順序也必須與溫控箱的順序和溫控箱的連（lián）接線一致，以防感溫電線被燒（shāo）壞的順序不一致（zhì）。
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、閥針式（shì）熱流道還必須連接模具上（shàng）控製閥針（zhēn）動作的電磁閥和氣缸上的進出（chū）氣管（guǎn）。
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、熱流道加熱時，必須每次打開溫控箱上的加熱開關一段，待溫度開始升高時再開啟下一段。不要一次（cì）打開它。
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、個別熱流（liú）道分水口處帶有水路密封圈的模具，必須在（zài）加熱熱流（liú）道時開啟模具冷卻係統。防止（zhǐ）分噴嘴上的加熱（rè）圈在高溫下燒壞水路密封圈。
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、如果熱嘴沒有出膠，不（bú）要隨意提高溫控（kòng）箱內設定的溫度（dù）或用槍（qiāng）烤嘴。應檢查螺杆溫度是否到位，螺杆噴嘴是否堵塞。（如果是閥針熱流道，還需要檢查電磁閥是否正常工作，氣缸是否通（tōng）風等）
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、
濟南（nán）注塑模具廠家提醒（xǐng）您（nín）在熱流道（dào）模具生產過程中不要清洗定模分型麵（開嘴熱流道）。防止熱流道內溶膠因受熱過（guò）大而分解爆裂，溶膠噴出燙傷操作人員。
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.
