An injection mechanism of an injection molding machine, comprising an injection platform support, an injection platform front plate and an injection platform rear plate located on the injection platform support, an injection cylinder group and a shifting cylinder group are installed on the injection platform front plate, and An oil motor and an injection piston rod are installed on the rear plate of the injection platform, and the injection piston rod is connected with the injection cylinder group. On the rod, the guide rod is installed in front of the support of the shooting platform; the bottom of the rear plate of the shooting platform is provided with a slider, and the slider is slidably connected with the linear guide rail, and the linear guide rail is installed on the The rear of the shooting platform support. The invention provides an injection mechanism of an injection molding machine with long service life, less damage caused by improper nozzle center adjustment, more rapid and stable injection, and high precision.
Description
(1) Technical field [0001] The invention relates to the field of injection molding machines, in particular to an injection mechanism of an injection molding machine. (2) Background technology [0002] The existing injection molding machines are basically guided by two parallel guide rods. figure 1 , and the guide rod also bears the weight of the injection part and the weight of the raw material while guiding, and the guide rod undergoes radial deformation under the action of gravity, which greatly reduces the accuracy of injection and material storage; and the guide rod and guide The gap fit between the sleeves has already determined that the precision of the structure is limited, and the friction between them is sliding friction, and the precision will become lower and lower as time goes by. [0003] Another example is the Chinese Patent No.: 02265526.3, the invention name is an improved utility model patent for the pre-molding guide system of an injection molding machine,...
