introduction：The internal stress of injection molded products is due to improper molding、Temperature change、Stress caused by solvent action, etc。Its essence is the formation of high elastic deformation frozen in the product。 Internal stress can affect the properties of molded products，It will also reduce the mechanical strength of the product perpendicular to the direction of flow，Causes plastic products to crack。 The internal stress has the orientation stress、Volume temperature stress、And the deformation stress of the product during release。 Dispersion and elimination of internal stress： Plastic material：Impurities in materials can easily cause internal stress，Multi-component plastic groups should be evenly dispersed，well-vented，The particles are plasticized uniformly during granulation，Product internal stress

introduction：The problem of poor bearing capacity often occurs in the operation of the reducer，According to the analysis of the working principle of Zibo reducer，There are three factors that affect the bearing capacity of the reducer： 1.The effect of the reducer itself The manufacturing accuracy and running speed of gear are the internal factors that affect the bearing capacity of reducer。The ideal motion of the gear pair is that the input and output speed are constant values，Due to gear machining、The existence of assembly errors，Gears move relative to each other during movement，Lead to transmission errors and gear vibration，Internal additional load is brought to the gear，At this time, the reducer will produce a larger noise

introduction：Working principle The butterfly pump relies on two butterfly rotors to rotate synchronously in reverse，Vacuum is generated at the inlet，Thereby inhaling the material to be transported。As shown above，The rotor chamber is enclosed in one space with the end cover，Two rotors divide the space into several smaller Spaces，Double pressa→b→c→dSequence run。In positionawhen，Only the inlet is filled with medium；To positionbwhen，AThe chamber is partially enclosed in the medium；To positioncwhen，AThe chamber communicates with the exit，meanwhileBThe chamber is partially enclosed in the medium；To positiondwhen，BThe room is the same as the exit。The rotor spun without ceasing，interface

introduction： The wall thickness of the strut protruding glue is used for assembly products、For separating objects and supporting other parts。Hollow struts can be used to insert pieces、Screw up。These applications must have sufficient strength to support the pressure without rupture。 Try not to use the prop alone，It should be connected to the outer wall or used with the stiffener as far as possible，The purpose is to strengthen the strength of the pillar and make the rubber flow smoother。In addition，Because the pillar is too high, it will cause gas trapping when the plastic parts are formed，Therefore, the height of the pillar is generally not more than two and a half times the diameter of the pillar。Method of strengthening the pillar”Especially struts away from the outer walls〔，In addition to usable

introduction：Rolling friction Friction when two objects in contact roll relative to each other or tend to roll relative to each other。The mechanism of rolling friction is different from sliding friction﹐It mainly comes from the rolling body producing bullets in the contact area-Plastic deformation﹐At the point of contact(Disjunction line)The contact pressure distribution in the contact area is asymmetrical﹐Causing the reaction of the supporting surfaceN eccentricity﹐And create frictionF (See picture Rolling friction diagram )。Use the normal reaction notationN Distance to the point of contact﹐According to the equilibrium conditions of the forces Where is the radius of rolling element﹔Is the rolling friction coefficient﹐Its dimension is length﹐Its value is associated with the material of the contact surface
