introduction： The requirements for a uniform heat balance on the hot runner plate mainly include the absence of local temperature differences as far as possible，Because when the probe(Torpedo body)It is heated indirectly by the hot runner system，The same temperature at the tip of the probe is a necessary prerequisite。The hot runner plate must have as little temperature fluctuation as possible one—Most pads should be as high as possible ——Heat loss should be as little as possible ——The temperature should be controlled。 To determine the heating capacity of the hot runner mold，The heating capacity of the hot runner plate has been proven according to150～300WeightsThe ratio of its results is successful

introduction：How the rice cooker works The rice cooker is made using a heating plate，Cook rice in the bottom of an aluminum pan。The heating plate contains a hot wire，The hot wire is controlled by an automatic switch。The main structure is shown in the figure。 There is a round hole in the center of the heating plate，There is a temperature-sensitive soft magnetic field in the hole，Its attached to the bottom of the pan by a spring。This is a pure ferrite。Its in...100℃Or below，Can be attracted by permanent magnets。But when it rises103℃when，Lose magnetism，No longer attracted to permanent magnets。 When the switch button is pressed，As shown in the figure(a)As indicated。The switch bar holds the magnet up to the top against a temperature-sensitive soft magnet。At this moment，

introduction：bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Its a mass production of mechanical parts，And the manufacturing accuracy requirements are very strict，There is a high degree of technical specialization，Therefore, for the vast majority of easy to buy bearing varieties，It should be more cost-effective to buy than to repair，Apart from economics，The repair of bearings is also technical，This requires the repairman to charge
