使用熱流道模具是降低成本的好方法（fǎ）。不僅減少了環境汙染，而且縮短了注塑製品的生（shēng）產周期，提高了工作效率。同時還可以提（tí）高注塑產（chǎn）品的質量（liàng），達到注塑產品質量的一致性。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解（jiě）決方法（fǎ）。

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（zhǔ）要可分為兩類：一類是帶（dài）有歧管和分水口的熱流道澆注係統；另一種是沒有歧管和主流道噴嘴（zuǐ）的熱流道澆注係統。熱（rè）流道澆注（zhù）係統的結構主要包括：主流道噴嘴、分流板、分流道、加熱和測溫部件、安裝和緊固部（bù）件，（個別（bié）熱流道還必須有：閥針、氣缸、隔（gé）熱帽、密封環等）組成。

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（shǐ）用前必須確認模（mó）具（jù）上熱流道承口內加熱線和感溫線的排列（liè）順序是否符合公司《注塑模具製（zhì）造規範（fàn）》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、模具上熱流（liú）道插座內的（de）發熱絲和感溫絲的順序也必須與溫控箱的（de）順序和溫控箱的連接線一致，以防感溫電（diàn）線被燒壞的順序不一致。

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、閥針式熱流道還必須連接模具上控製閥針動作的電磁閥和氣缸上的進出氣管。

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、熱流道加熱時，必須每次打開溫控箱上的（de）加熱開關一段，待溫度開始升高時再開啟下（xià）一段。不要一次打開它。

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，必須在加熱熱流道時開（kāi）啟模具冷卻係統。防止分噴嘴上的加熱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（chū）膠，不要隨意提高溫控箱（xiāng）內設定（dìng）的溫度或用槍烤嘴。首先應檢查螺杆溫度是否到位，螺杆噴嘴是（shì）否（fǒu）堵塞。（如果是閥針熱流道（dào），還需要檢查電磁閥（fá）是否正常工作，氣缸是否通風等）

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、濟南注塑模具廠家提醒您在熱流道模具生產過程中不要清洗定模分（fèn）型麵（開嘴熱流道）。防（fáng）止熱流道內（nèi）溶膠因受（shòu）熱過大而分解爆裂，溶膠噴出燙傷操作人員（yuán）。

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.
