精密注塑机的结构特点
Structure characteristics of precision injection molding machine
1) 由于精密注射机注射压力高，这就要强调合模系统的刚度。动、定模板的平行度控制在0.05～0.08mm 的范围内。
1) Due to the high injection pressure of the precision injection machine, it is necessary to emphasize the rigidity of the mold closing system. The parallelism of moving and fixed formwork shall be controlled within the range of 0.05-0.08mm.
2) 要求对低压模具的保护及合模力大小精度的控制。因为合模力的大小要影响模具变形的程度，最终要影响到制件的尺寸公差。
2) It is required to protect the low-pressure die and control the precision of die closing force. Because the size of the clamping force will affect the degree of die deformation, and ultimately affect the dimensional tolerance of the workpiece.
3) 启、闭模速度要快，一般在60mm/s左右。
3) The opening and closing speed of the formwork shall be fast, generally around 60mm / s.
4) 塑化部件: 螺杆、螺杆头、止逆环、料保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 筒等, 要设计成塑化能力强、均化程度好、注射效率高的结构形式；螺杆驱动扭矩要大，并能无级变速。
4) Plasticizing parts: screw, screw head, check ring, barrel, etc. shall be designed into a structure with strong plasticizing ability, good homogenization degree and high injection efficiency; the driving torque of screw shall be large and can be continuously variable
