塑料井盖模具的设计
发布人:管理员   发布时间:2020-10-30

塑料井盖模具设计是模具的根本,设计导致整体产品出现不良品和企业生产效率结构设计问题,冲模结构不合理,细长凸模没有设计加固装置,出料口不畅现堆集,卸料力过大使凸模承受交变载荷加剧等。
Mold design of plastic manhole cover is the fundamental of the mold. The design results in defective products and structural design problems of enterprise production efficiency. The die structure is unreasonable. There is no reinforcement device designed for the slender punch. The discharge port is not smooth and is piled up. If the unloading force is too high, the punch will bear the alternating load.

塑料井盖模具的设计制造过程极为繁琐,影响它的要素也挺多。凝土构件模具,塑料井盖模具浇注系统是井盖模具构造设计中的一个重要组成局部,也是塑料熔体进入模具型腔的独一通道。

它的几何外形及构造尺寸设计的合理与否,直接影响到聚合物熔体在模具通道中的流变特性及填充效果,进而影响到最终塑件的成型质量与模具整体构造设计的复杂水平。
Whether the geometric shape and structural dimension design is reasonable or not directly affects the rheological characteristics and filling effect of polymer melt in the mold channel, and then affects the molding quality of the final plastic parts and the complexity level of the overall structure design of the mold.

塑料井盖模具对应的加工设备是塑料注射成型机,塑料首先在注射机底加热料筒内受热熔融,然后在注射机的螺杆或柱塞推动下,经注射机喷嘴和模具的浇注系统进入模具型腔,塑料冷却硬化成型,脱模得到制品。
The corresponding processing equipment of plastic well cover mold is plastic injection molding machine. Firstly, the plastic is heated and melted in the heating barrel at the bottom of the injection machine, and then driven by the screw or plunger of the injection machine, it enters into the mold cavity through the injection nozzle and the pouring system of the mold, and the plastic is cooled and hardened into the mold, and demoulded to obtain the products.
