【文章內(nèi)容簡介】 g screw,35% a plunger (concentrated in the smaller machine size),and 5%a screw pot. Many of the problems connected with in jection molding arises because the densities of polymers change so markedly with 外 文 翻 譯 temperature and temperatures,the density of a polymer is considerably cower than at room temperature,provided the pressure is the ,if modls were filled at atmospheric pressure, “shrinkage”would make the molding deviate form the shape of the mold. To pensate for this poor effect, molds are filled at high pressure presses the polymer and allows more materials to flow into the mold,shrinkage is reduced and better quality moldings are a moldmounting pattern of bolt holes or “T” rods are members of the clamping force actuating machanism that serve as the tension members of clamp when it is holding the mold is a provision in the claming unit that actuates a mechanism within the mold to eject themolded part(s) form the ejection actuating force may be applied hydraulically or pneumatically by a cylinder(s) attached to the moving plate,or mechanically by the opening stroke of the moving plate. The function of a mold is twofold :imparting the desired shape to the plasticized polymer and cooling the injection molded is basically made up of two sets of ponents :the cavities and cores and the base in which the cavities and cores are mounted. The mold ,which contains one or more 外 文 翻 譯 cavities,consists of two basic parts :(1) a stationary molds half one the side where the plastic is injected,(2)Amoving half on the closing or ejector side of the machine. The separation between the two mold halves is called the parting some cases th
