我国的高速护坡模具有望创造新的历史****点,市场需求庞大是我国刀具行业兴旺发展的重要因素。在消费的刺激下,我国的刀具生产规模正在不断扩大。在刀具市场的推动下,我国的刀具模具的市场需求必然会得到提升,将会促进国内刀具模具产业更好发展。高速护坡模具变形:在生产过程中注塑护坡钢模具在出模时变形了,就要考虑到,模温、料温和产品出模时温度较高,还是保压时间不够充足和残余应力的作用等非设计原因,或者是护坡钢模具产品壁厚薄不均匀等都要考虑到。
The high-speed slope protection molds in China are expected to create new historical points, and the huge market demand is an important factor for the prosperous development of China's cutting tool industry. Under the stimulation of consumption, the scale of tool production in China is constantly expanding. Driven by the cutting tool market, the market demand for cutting tool molds in China will inevitably increase, which will promote the better development of the domestic cutting tool mold industry. High speed slope protection mold deformation: During the production process, if the injection molding slope protection steel mold deforms during demolding, it is necessary to consider non design reasons such as mold temperature, material temperature, high temperature during product demolding, insufficient holding time, and residual stress, or uneven wall thickness of the slope protection steel mold product.
高速护坡模具断裂:原材料填的过多,顶杆太小又太少了、顶速太快、粗温不够高等,有嵌件的预热不够有时候也会造成裂痕。塑模在,改善材料,不同的材料可产生不同类型的模具积垢,从薄的易流动的到厚的松软的。薄的易流动的积垢可能由低分子聚合物组分造成,它们在模具出口处挥发并沉积于模具表面。厚的松软的积垢则往往是由熔体内部局部的泡沫造成,如材料之间的兼容问题,或模具内的应力过高。在这里,需要留意树脂内是否有过多的水分和树脂是否降解退化,以及熔体的断裂,或通风不够充分。改善高速护坡模具在模具表面涂覆含氟聚合物防止模具积垢,如聚四氟乙烯,现已取得一定的成功。更为有效的方法是金属涂层,结合模具内部涂覆的含氟聚合物,可减少模具出口处的应力
High speed slope protection mold fracture: Excessive filling of raw materials, too small and too few top rods, too fast top speed, insufficient rough temperature, and insufficient preheating of embedded parts can sometimes cause cracks. Plastic molds can improve materials, and different materials can produce different types of mold deposits, ranging from thin and easy to flow to thick and soft. Thin and easily flowing deposits may be caused by low molecular weight polymer components, which evaporate and deposit on the surface of the mold at the outlet. Thick and soft scale is often caused by local foam inside the melt, such as compatibility problems between materials, or excessive stress in the mold. Here, it is necessary to pay attention to whether there is excessive moisture inside the resin, whether the resin has degraded, and whether the melt has broken or insufficient ventilation. Improving the coating of fluorinated polymers on the surface of high-speed slope protection molds to prevent mold fouling, such as polytetrafluoroethylene, has achieved certain success. A more effective method is metal coating, combined with fluorinated polymers coated inside the mold, to reduce stress at the mold outlet
