注塑模具(jù)是(shì)一種生產塑膠製品的工具,也是賦予塑膠製品完整結構和精確尺寸的(de)工具。下麵
濟南注塑加工廠家(jiā)來講講注塑模具(jù)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(zhù)塑(sù)模(mó)具結構
Injection Mold Structure
A、成(chéng)型零部件:也就是我們通常所說的前、後模CORE,也(yě)是與產品聯(lián)係緊密的部位;
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、澆注係統:熔融塑膠從(cóng)噴嘴(zuǐ)引向型腔的流道,可分為:主(zhǔ)流道、分(fèn)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、導向係(xì)統:確定前、後(hòu)模合模的時候的相對位置,一般有導柱、導套,要的情況上(shàng),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(jié)構:就是將膠件從模具中頂出的裝置(zhì),常(cháng)用(yòng)的有:頂針、頂板、司筒等(děng);
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、溫度調節係統:為滿足注塑成形工藝對模具溫度的要求,在前(qián)後模所加的冷卻水道;
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(dǎo)扣即與脫模方(fāng)向不一(yī)致的結(jié)構的(de)時候就得使用行位,常見的形式:滑塊、斜頂、抽芯等(děng);
F. Lateral parting and lateral core pulling;

G、排氣結構:常見的排氣形式有兩種:排(pái)氣槽、成形零部件間隙。為了在注塑過程中排除型腔中(zhōng)的空氣和成型過程中產生的氣體,常在分型麵設置排氣槽。設置排氣槽的原則(zé)是,在不影響溢料及披(pī)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,難免會發生使用過程中的正(zhèng)常磨損,當模具出現損壞或者變形等等的時候,為了防止(zhǐ)注(zhù)塑機生產出來(lái)的產品出現殘次品等,我(wǒ)們就(jiù)需要及時對模具進行修(xiū)模處理(lǐ)。
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(jiǎn)查模具的損壞或者磨損的(de)程度,其次根據模具的損壞程度,參照正常的模具來製定相應(yīng)的修模方案,後也是重要的,就是對模具進(jìn)行維修,在很多時候(hòu),其(qí)實維修保養工程師都是在(zài)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(jié)構、尺寸”,這就要求我們修模技工在設計到(dào)尺寸(cùn)改變的(de)時候應(yīng)先拿好數再作下一步工作。
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.lsjtcyjt.cn Consult.
