使用熱流道模具是降低成本的好方法。不僅減少了環(huán)境污染，而且縮短了注塑制品的生產(chǎn)周期，提高了工作效率。同時還可以提高注塑產(chǎn)品的質(zhì)量，達(dá)到注塑產(chǎn)品質(zhì)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(diǎn)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.
熱流道澆注系統(tǒng)主要可分為兩類：一類是帶有歧管和分水口的熱流道澆注系統(tǒng)；另一種是沒有歧管和主流道噴嘴的熱流道澆注系統(tǒng)。熱流道澆注系統(tǒng)的結(jié)構(gòu)主要包括：主流道噴嘴、分流板、分流道、加熱和測溫部件、安裝和緊固部件，（個別熱流道還必須有：閥針、氣缸、隔熱帽、密封環(huán)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、使用前必須確認(rèn)模具上熱流道承口內(nèi)加熱線和感溫線的排列順序是否符合公司《注塑模具制造規(guī)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、模具上熱流道插座內(nèi)的發(fā)熱絲和感溫絲的順序也必須與溫控箱的順序和溫控箱的連接線一致，以防感溫電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制閥針動作的電磁閥和氣缸上的進(jìn)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加熱開關(guān)一段，待溫度開始升高時再開啟下一段。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啟模具冷卻系統(tǒng)。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、如果熱嘴沒有出膠，不要隨意提高溫控箱內(nèi)設(shè)定的溫度或用槍烤嘴。應(yīng)檢查螺桿溫度是否到位，螺桿噴嘴是否堵塞。（如果是閥針熱流道，還需要檢查電磁閥是否正常工作，氣缸是否通風(fēng)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(jì)南注塑模具廠家提醒您在熱流道模具生產(chǎn)過程中不要清洗定模分型面（開嘴熱流道）。防止熱流道內(nèi)溶膠因受熱過大而分解爆裂，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.
