注塑机螺杆一般情况下可分为加料段、压缩段、均化段。不同的螺杆三段所占的比值不一样,螺杆槽深不一样,螺杆底径过渡形式不一样。
  螺杆是注塑机的重要部件。它的作用是对塑料进行输送、压实、熔化、搅拌和施压。所有这些都是通过螺杆在机筒内的旋转来完成的。
  需要注意的内容如下:
(1)给螺栓的螺纹和螺杆头罗纹表面均匀涂上高温防紧蚀膏,以防日后拧不出来;
(2)螺杆型号确认;
(3)安装螺杆头确认止逆环介子前后端面与螺杆贴合端面要吻合;
(4)注意在把螺杆装入料筒时止逆环要用手扶住轻轻往里推,预防止逆环挂到料筒端面;
(5)注意螺杆头拧紧方向是逆时针;
(6)螺丝必须是强度级别12.9级的优质螺栓,给螺栓的螺纹表面涂上高温防紧蚀膏;
(7)前法兰与料筒螺丝一定要对称均匀拧紧;
(8)注塑机螺杆料筒冷却系统要清理干净,保证通畅。注意正确使用生料带,缠在工艺螺塞上。
Injection machine machine of of injection injection machine
The injection molding machine screw can generally be divided into feeding section, compression section and homogenization section. The ratio of different screw three sections is different, the screw groove depth is different, and the screw bottom diameter transition form is different.
Screw rod is an important part of the injection molding machine. Its role is to transport, compact, melt, stir, and pressure the plastic. All of this is done by the rotation of the screw in the barrel.
Note that the contents are as follows:
1. Apply the thread and the thread surface of the bolt evenly with high temperature anti-corrosion paste to prevent untwisting out in the future;
2, screw model confirmation;
3. Install the screw head to confirm that the front and rear end of the ring pion should coincide with the end of the screw;
4. Pay attention to put the screw into the material cylinder and push it gently to prevent the reverse ring from hanging to the end surface of the material cylinder;
5. Note that the tightening direction of the screw head is counterclockwise;
6, the screw must be a high quality bolt strength level 12.9 level, to the thread surface of the bolt coated with high temperature anti-corrosion paste;
7, the front flange and the material cylinder screws must be tightened symmetrical and evenly;
8, injection molding machine screw cylinder cooling system should be cleaned up to ensure smooth. Note the correct use of the raw material belt, wrapped around the process screw plug.
