一、概述橡胶压铸模是将胶料放入压缩室,利用柱塞传递压力,通过浇铸孔将胶料压入型腔而硫化橡胶制品的模具。由于胶料在压制过程中受到强烈的挤切作用,使胶料中的配合剂分散得更加均匀,因此产品质量稳定,制品毛边少,尺寸准确。它具有和注压法相同而优于模压法制品的特点,如扯断力高,耐弯曲疲劳好和与金属结合强度高等,同时又可克服注压法中的高温快速硫化、交联不完全稳定而使定伸强度较低,压缩变形较大的缺点。
First, an overview of rubber die-casting mold is the rubber compound into the compression chamber, the use of plunger pressure transmission through the casting hole will be pressed into the cavity rubber and vulcanized rubber products mold. As the rubber compound in the pressing process by a strong squeeze cut, the rubber compound in the more evenly dispersed, so the product quality and stability, less flash products, the size of accurate. It has the same pressure injection method and superior to molded products, such as high breaking force, bending fatigue resistance and high bonding strength with the metal, but also can overcome the pressure injection method of rapid curing high temperature, crosslinking is not complete Stable so that the lower fixed strength, compression deformation larger shortcomings.
