试模程序要点（Main points of die test procedure） I. Preface When we got a new pair of mould proofing test, we are always eager to try out some early results and a prayer process in order to avoid the waste of time and trouble. But here we must remind two points: first, mold designers and manufacturing technicians sometimes also mistakes; in our trial, if not alert, may cause great harm to small errors. Second, the result of the trial mold is to ensure the smooth production later. If no reasonable steps are taken and proper records are made during the trial run, there is no guarantee that the production will be carried out smoothly. We are more emphasis is that the smooth use of the mold will increase the profits quickly, otherwise the cost will be more than the cost of the mold itself.. Two, the notice before testing 1. understand the relevant information about the die: The best to design the mold surface for detailed analysis, and often die tryout work in technician. 2. check the mechanical coordination action on the worktable first: Should pay attention to scratches, missing parts and loose, etc., whether the movement of the slider to the road, the trachea and trachea joints are leaking, the opening of the mold, if limited, should also be marked on the mold. If the above action can be done before the die hanging, it can avoid finding problems during the die hanging, and then the waste of the work time happened to remove the die. 3. when each action is properly determined the mold, to choose a suitable mold injection machine, should pay attention to in the selection (a) injection capacity; (b) the width of the guide bar (c) maximum opening (d) accessories Are they congruent?. Everything is confirmed that no problem, then the next step is to hang the mold, the suspension should pay attention to all the clip on the lock template and die before lifting, do not take off, so as not to clamp the template loose or broken, so that the mold fall. When the mold is loaded, the mecha
