[Previous technology] The mold adjustment structure of injection molding machine (also known as injection molding machine) is mainly used to adjust the capacity of the mold clamping device of injection molding machine. It is commonly used on general elbow mold clamping and two-plate injection molding machines. In the prior art, the mold adjustment mechanism of the injection molding machine is driven by a motor connected to the driving wheel of the motor, which pulls the chain and drives the large adjustment sprocket to rotate so as to push the mold clamping tail plate to slide along the pull rod to achieve the function of adjusting the modulus of the mold clamping device. It is extremely important to adjust the tension (pre-tightening force) of the chain during the assembly process. Too tight will pull the chain off, and parts will be damaged. Too loose will cause the chain to fall off and jump teeth. [New content] In order to overcome the shortcomings of the prior art, the purpose of this creation is to provide an eccentric mold-adjusting transmission structure of an injection molding machine, which is simple to use and easy to adjust. In order to achieve the above purpose, the technical solution of this creation is: an eccentric mold-adjusting transmission structure of an injection molding machine, including a mold clamping tail plate, each of which is provided with four through holes at four corners; four tie rods respectively passing through the mold clamping tail plate Four through-holes; four large die-adjusting sprocket wheels are respectively set outside the four tie rods; a motor for providing power required for transmission; a driving wheel; and a chain connecting the driving wheel And mold adjustment large sprocket; characterized in that the eccentric mold adjustment transmission structure is further provided
