注塑模具结构与维护事项

来源:/ 日期:2022-09-14

注塑模具是一种生产塑胶制品的工具,也是赋予塑胶制品完整结构和精确尺寸的工具。下面济南注塑加工厂家来讲讲注塑模具结构与维护事项。
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.
注塑模具结构
Injection Mold Structure
A、成型零部件:也就是我们通常所说的前、后模CORE,也是与产品联系紧密的部位;
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、浇注系统:熔融塑胶从喷嘴引向型腔的流道,可分为:主流道、分流道、浇口、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、导向系统:确定前、后模合模的时候的相对位置,一般有导柱、导套,要的情况上,顶出部分也需导柱、导套定位;
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、脱模结构:就是将胶件从模具中顶出的装置,常用的有:顶针、顶板、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、温度调节系统:为满足注塑成形工艺对模具温度的要求,在前后模所加的冷却水道;
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、侧向分型及侧向抽芯:当胶件存在倒扣即与脱模方向不一致的结构的时候就得使用行位,常见的形式:滑块、斜顶、抽芯等;
F. Lateral parting and lateral core pulling;

G、排气结构:常见的排气形式有两种:排气槽、成形零部件间隙。为了在注塑过程中排除型腔中的空气和成型过程中产生的气体,常在分型面设置排气槽。设置排气槽的原则是,在不影响溢料及披锋的时候,应尽可能大的排气槽。而镶针、顶针、镶件则是利用成。
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.
注塑模具的维护
Maintenance of injection mold
注塑模具在正常使用过程中,难免会发生使用过程中的正常磨损,当模具出现损坏或者变形等等的时候,为了防止注塑机生产出来的产品出现残次品等,我们就需要及时对模具进行修模处理。
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.
我们先检查模具的损坏或者磨损的程度,其次根据模具的损坏程度,参照正常的模具来制定相应的修模方案,后也是重要的,就是对模具进行维修,在很多时候,其实维修保养工程师都是在无图纸的情况下进行的,而我们维修的原则为“不影响塑件的结构、尺寸”,这就要求我们修模技工在设计到尺寸改变的时候应先拿好数再作下一步工作。
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.
此外做任何事情,问题须为重,模具维修、保养是与模具、设备(钢)打交道,对此问题须引起高度重视。更多注意事项就来我们网站咨询吧。
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 Consult.
