| U型槽模具作为经常使用的一种,对于整个市场的激烈竞争来说,u型槽模具不得不进行改善,增加u型槽钢模具的设计理念才是关键,打造全新模具的才是最主要,全新的模具设计是提高质量的最重要的一步,需要考虑的因素有很多,包括模具材料的选用、模具结构的可实用性/安全性、模具零件的可加工性以及模具维修的方便性. As one of the most frequently used moulds, U-groove moulds have to be improved in the fierce competition of the whole market. The key is to increase the design concept of U-groove steel moulds. The most important thing is to create a new moulds. The new design of moulds is the most important step to improve the quality of moulds. There are many factors to be considered, including the selection of die materials and the practicability of die structure. Safety, machinability of die parts and convenience of die maintenance. 当u型槽模具的工作温度较高进,会使硬度和强度下降,导致模具早期磨损或产生塑性变形而失效.因此,模具材料应具有较高的抗回火稳定性,以保证模具在工作温度下,具有较高的硬度和强度.U型槽模具在工作过程中处于反复加热和冷却的状态,使型腔表面蠕动泵 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 受拉、压力变应力的作用,引起表面龟裂和剥落,增大摩擦力,阻碍塑性变形,降低了尺寸精度,从而导致模具失效. U型槽模具浇注系统:将塑料由少射机喷嘴引向型腔的流道称为浇注系统,由主流道,分流道,浇口.热交换系统:为了满足注射成形工艺对电缆槽模具温度的要求需要对模具温度进行较精确的控制.顶出系统:实现塑胶产品脱模的机构,其结构形式很多,最常用的是顶针、司筒和推板等脱模机构.最新生产的钢模具择需要3-8毫米的钢板进行卷曲、裁剪、造型、加固、焊接、拼装等手续,虽然比模具制作麻烦,但是寿命确实塑料模具的几十倍.钢模具有高质感、抗耐磨、光滑度、密实度好的特点. When the working temperature of the U-groove die is higher, the hardness and strength will decrease, leading to early wear or plastic deformation of the die and failure. Therefore, the die material should have higher temper resistance stability to ensure that the die has higher hardness and strength at working temperature. The U-groove die is in the state of repeated heating and cooling in the working process, so that the surface of the cavity is tension and pressure response. The effect of force causes surface cracking and peeling, increases friction, hinders plastic deformation and reduces dimensional accuracy, which leads to die failure. U-groove mould pouring system: the runner that leads plastic from the nozzle of less injector to the cavity is called pouring system, which includes main runner, shunt runner and gate. Heat exchange system: in order to meet the requirement of injection moulding process for the temperature of cable groove mould, the temperature of the mould needs to be controlled. Ejection system: The structure of ejection mechanism for plastic products has many forms. The most commonly used ones are ejection mechanism such as ejector pin, cylinder and pusher. The latest steel die selection requires 3-8mm steel plate for curling, cutting, moulding, strengthening, welding, assembling and other procedures. Although it is more troublesome than die making, the life of steel die is dozens of times longer than that of plastic die. It has the characteristics of high texture, wear resistance, smoothness and compactness. |
