高光成型**模具控温的详细介绍 高光无夹线无熔接痕注塑/高光成型**模具控温 RHCM高光过热水模温控制机 RHCM superheated water high-gloss traceless injection mould 急速升降模温技术 Technology of quick rising and drop of mold temperature 传统注塑模具温度控制的不足之处如下 Disadvantages of the traditional temperature control technology for injection molds: 无法满足高光注塑中快速升温及快速降温的需要。 The need of high-gloss injection molding for quick temperature rising and drop cannot be met. 升温幅度较小，制品表面的溶接痕只能得到减轻而无法消除。 The margin of temperature rising is very small. As a result, the welding traces on product surfaces can be alleviated rather than removed thoroughly. 由于塑料硬度越高，流动性越差。因此采用此种工艺，制品表面的硬度只能达到HB级，无法满足实际使用需要。 Due to the great hardness and poor fluidity of plastics, this technology can only make the surface hardness of a product grade HB, failing to meet the actual requirements of application. 模具升温时受热膨胀，降温时又会收缩，使锁模力很不稳定。 Due to the mold’s expansion when in temperature rising and its shrinkage when in temperature drop, the clamping force is quite unstable. 容易造成制品打不满，烧焦、内应力大等各种缺陷。 Thus, the products are easy to suffer from short molding, scorching, excessive internal stress and other defects. 模具的配置 Configuration of die 模具内表面要求非常高的光洁度，以确保制品的表面质量。 The mold’s inner surface should be very smooth, so as to ensure high surface quality for products. 模具内部开设管道必须合理，以确保可以快速升温和降温。 The pipelines arranged in the mold must be rational so that temperature can rise or drop quickly. 模具内部的管道应该导热性能良好。 The mold’s internal pipelines should be of good heat conductivility. 由于生产过程中需要不停加温及降温，模具选用的钢材要好。 The necessity to have temperature rise and drop frequently in production makes it necessary to select good steel materials for the mold. 组织结构均匀，热胀冷缩系数小。 The organizational structure is even and the expansion and shrinkage coefficients are small. 在使用过程中要尤其注重模具的保养，确保干燥、无尘。 Pay special attention to the mold’s maintenance when in use, making it dry and dustless.
