塑料注射模各模板间相对位置不仅在运行中要求稳定,而且要求在拆卸或修复后复位准确。动、定模的定位精度与紧固的稳定性轻者引起型腔位移,制件外形尺寸及精度受影响,严重时引起模具损坏,故注射模对紧固件提出严格的可靠性要求。动、定模模板紧固方式如下:1.螺销钉紧固法这种结构在我国广泛流行,定位元件——销钉通常贯穿整个销孔,但有时由于模
The relative position of the plastic injection molds between the templates not only requires stability during operation, but also requires accurate resetting after disassembly or repair. Dynamic and fixed mold positioning accuracy and tightness of the stability of the light caused by the displacement of the cavity, the workpiece shape and size accuracy affected, causing severe mold damage, so the injection mold on the fastener to the strict reliability requirements. Dynamic, fixed mold template fastening methods are as follows: 1. Screw pin fastening method This structure is widespread in our country, positioning components - pin usually runs through the pin hole, but sometimes due to die
