自封袋的注塑擠出怎么使用?

自封塑模具的溫度,要比型坯模具的溫度低10~30℃左右。壓力。注射壓力及保壓壓力。注射壓力可在注射機額外壓力范圍內調整。注射壓力缺乏,型坯外表不平坦,熔體充模量缺乏,易造成型坯缺口、漏底、螺紋尺度缺乏等缺點;注射壓力過高,易呈現型坯芯棒偏斜,型坯呈現飛邊。注射壓力可控制在(2.0~2.5)X105Pa。熔體被注射充模后,注射機仍需堅持滿足的保壓壓力,才干得到尺度準確、外表平坦光亮、比容值較低的型坯。
The temperature of self sealing plastic mold is about 10 ~ 30 ℃ lower than that of parison mold. Pressure. Injection pressure and holding pressure. The injection pressure can be adjusted within the additional pressure range of the injection machine. Lack of injection pressure, uneven surface of parison, lack of melt filling modulus, easy to create parison gap, bottom leakage, lack of thread size and so on; If the injection pressure is too high, it is easy to show parison mandrel deflection and parison flash. The injection pressure can be controlled at (2.0 ~ 2.5) x105pa. After the melt is injected and filled, the injection machine still needs to adhere to the pressure holding pressure to obtain the parison with accurate scale, flat and bright appearance and low specific volume value.
與此同時,鎖模設備亦需要堅持滿足的鎖模力,以防脹模。模具的鎖模力與注射壓力及型腔投影面積有關。吹脹氣壓。吹脹氣壓是指在吹塑模具內將型坯吹脹成容器的壓縮空氣壓力。 陰陽自封袋?壓縮空氣壓力,通常控制在0.8~1.OMPa范圍內。進步吹脹氣壓,可削減型坯吹脹缺乏、肩部變形、瓶身洼陷等缺點;進步壓縮空氣的體積流量(充氣速度)可進步出產功率,改進容器的外表光澤度和壁厚均勻性。
At the same time, the mold locking equipment also needs to adhere to the mold locking force to prevent mold expansion. The clamping force of the mold is related to the injection pressure and the projected area of the cavity. Inflation pressure. The blowing pressure refers to the compressed air pressure that blows the parison into a container in the blow mold. Yin Yang self sealing bag? The compressed air pressure is usually controlled within the range of 0.8 ~ 1.ompa. Improving the blowing pressure can reduce the defects such as lack of parison blowing, shoulder deformation and bottle body depression; Increasing the volume flow (inflation speed) of compressed air can improve the production power and improve the surface gloss and wall thickness uniformity of the container.

時刻。注射吹塑成型周期是各段技術進程所需時刻的歸納。它包含物料混煉塑化時刻、注射時刻、模具等待時刻、吹塑時刻、模具啟閉間隔時刻,通常為10-20s。成型周期是在確保容器質量的條件下,獲得高出產功率的歸納平衡成果。加速物料塑化時刻,可縮短成型周期,但以不影響物料塑化質量為條件;延伸注射時刻、保壓時刻、吹脹時刻,有利于改進容器的質量,卻會下降出產功率。 自封袋注射吹塑成型的開車操作應按照以下過程進行。
Moment. Injection blow molding cycle is the induction of the time required for each technical process. It includes material mixing and plasticizing time, injection time, mold waiting time, blow molding time and mold opening and closing interval, usually 10-20s. Forming cycle is the inductive balance result of obtaining high production power under the condition of ensuring container quality. Accelerating the plasticizing time of materials can shorten the forming cycle, but it does not affect the plasticizing quality of materials; Extending the injection time, pressure holding time and inflation time is conducive to improving the quality of the container, but will reduce the production power. The start-up operation of self sealing bag injection blow molding shall be carried out according to the following process.
接通電源,按技術需求對料筒進行加熱,到達設定溫度后,應恒溫lh,使各點溫度均勻共同。翻開料斗座冷卻水開關,對料斗座進行冷卻,以防加料口呈現“架橋”表象。選用手動對空注射,調查物料塑化狀況,若物料塑化均勻即可出產開端。通過幾個循環操作,芯棒、型腔和吹塑模的溫度趨于合適,就可以發動注射機的主動操作。
Turn on the power supply and heat the barrel according to the technical requirements. After reaching the set temperature, keep the temperature constant for 1h to make the temperature of each point uniform and common. Turn on the cooling water switch of the hopper base to cool the hopper base to prevent the feeding port from showing the appearance of "bridging". Select manual air injection to investigate the plasticization of materials. If the materials are plasticized evenly, the production can start. Through several cycle operations, the temperature of the mandrel, cavity and blow mold tends to be appropriate, and the active operation of the injection machine can be started.
脫模工位要對制品進行抽檢,看其質量、尺度是不是符合需求,有無飛邊、缺料和破洞。芯棒上恣意部位若是黏附有塑料,容器的壁厚就會發生不均勻,故應從每個芯棒取樣,送至質量查驗部分進行查驗,若是合格,即可正常出產。注射吹塑成型的泊車操作應按照以下過程進行。把操作方法選擇開關轉變到手動方位。
The demoulding station shall conduct sampling inspection on the products to see whether their quality and scale meet the requirements, and whether there are flash, material shortage and holes. If any part of the mandrel is attached with plastic, the wall thickness of the container will be uneven. Therefore, each mandrel shall be sampled and sent to the quality inspection part for inspection. If it is qualified, it can be produced normally. The parking operation of injection blow molding shall be carried out according to the following process. Change the operation method selection switch to manual position.
封閉加料擋板,中止持續向料筒供料。將模具置于半合模狀況。注射座推回。整理料筒中的余料,對加工中易分化的樹脂如PVC等,應選用螺桿清潔專用料清潔潔凈。把一切操作開關和按鈕置于斷開方位,斷電、斷水、斷氣。泊車后要擦洗機器部位,并清掃環境衛生。
Close the feeding baffle and stop the continuous feeding to the barrel. Place the mold in the semi closed state. Push the injection seat back. For the remaining materials in the finishing barrel, the resin that is easy to differentiate in processing, such as PVC, shall be cleaned with special materials for screw cleaning. Put all operation switches and buttons in the off position to cut off power, water and gas. After parking, scrub the machine parts and clean the environment.
