注塑模具是一種生產(chǎn)塑膠制品的工具，也是賦予塑膠制品完整結構和精確尺寸的工具。下面
濟南注塑加工廠家來講講注塑模具結構與維護事項。
Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and accurate size. Next, Jinan injection molding processing factory will talk about injection mold structure and maintenance.
注塑模具結構
Injection Mold Structure
A、成型零部件：也就是我們通常所說的前、后模CORE，也是與產(chǎn)品聯(lián)系緊密的部位；
A. Molding parts: that is, the front and rear mold CORE, which we usually call, is also the part closely related to the product;
B、澆注系統(tǒng)：熔融塑膠從噴嘴引向型腔的流道，可分為：主流道、分流道、澆口、冷料井等；
B. Gating system: the runner of the molten plastic from the nozzle to the cavity can be divided into: main runner, splitter, gate, cold well, etc;
C、導向系統(tǒng)：確定前、后模合模的時候的相對位置，一般有導柱、導套，要的情況上，頂出部分也需導柱、導套定位；
C. Guide system: determine the relative position of the front and rear mold when closing the mold. Generally, there are guide posts and guide sleeves. If necessary, the ejection part also needs to be positioned by the guide posts and guide sleeves;
D、脫模結構：就是將膠件從模具中頂出的裝置，常用的有：頂針、頂板、司筒等；
D. Demoulding structure: it is a device to eject the rubber parts from the mold, commonly used are: thimble, top plate, ejector sleeve, etc;
E、溫度調(diào)節(jié)系統(tǒng)：為滿足注塑成形工藝對模具溫度的要求，在前后模所加的冷卻水道；
E. Temperature regulating system: to meet the requirements of injection molding process on mold temperature, cooling channels are added to the front and rear molds;
F、側向分型及側向抽芯：當膠件存在倒扣即與脫模方向不一致的結構的時候就得使用行位，常見的形式：滑塊、斜頂、抽芯等；
F. Lateral parting and lateral core pulling;
G、排氣結構：常見的排氣形式有兩種：排氣槽、成形零部件間隙。為了在注塑過程中排除型腔中的空氣和成型過程中產(chǎn)生的氣體，常在分型面設置排氣槽。設置排氣槽的原則是，在不影響溢料及披鋒的時候，應盡可能大的排氣槽。而鑲針、頂針、鑲件則是利用成。
G. Exhaust structure: there are two common exhaust forms: exhaust slot and clearance between formed parts. In order to eliminate the air in the mold cavity and the gas generated in the molding process during the injection molding process, an exhaust slot is often set on the parting surface. The principle of setting the exhaust slot is that the exhaust slot should be as large as possible when it does not affect the overflow and the flaring. The core pin, thimble and insert are used.
注塑模具的維護
Maintenance of injection mold
注塑模具在正常使用過程中，難免會發(fā)生使用過程中的正常磨損，當模具出現(xiàn)損壞或者變形等等的時候，為了防止注塑機生產(chǎn)出來的產(chǎn)品出現(xiàn)殘次品等，我們就需要及時對模具進行修模處理。
During the normal use of the injection mold, it is inevitable that normal wear will occur during the use. When the mold is damaged or deformed, we need to repair the mold in time to prevent defective products from occurring in the products produced by the injection molding machine.
我們先檢查模具的損壞或者磨損的程度，其次根據(jù)模具的損壞程度，參照正常的模具來制定相應的修模方案，后也是重要的，就是對模具進行維修，在很多時候，其實維修保養(yǎng)工程師都是在無圖紙的情況下進行的，而我們維修的原則為“不影響塑件的結構、尺寸”，這就要求我們修模技工在設計到尺寸改變的時候應先拿好數(shù)再作下一步工作。
We first check the damage or wear degree of the mold, and then formulate the corresponding mold repair plan according to the damage degree of the mold and referring to the normal mold. It is also important to repair the mold. In many cases, the maintenance engineer actually carries out the maintenance without drawing, and our maintenance principle is "do not affect the structure and size of the plastic parts", This requires our mold repair technicians to take good numbers before doing the next step when designing to change the size.
In addition, the safety problem must be the most important when doing anything. Mold repair and maintenance are related to molds and equipment (steel), which must be paid great attention to. More notes on our website http://www.820hu.com Consult.
