When the mold is closed, the injection motor of the melt-glue injection assembly 5 rotates, driving the injection screw to rotate directly, pulling the entire melt-glue injection assembly 5 and the screw forward quickly, injecting the glue at the front end of the melt-glue cylinder into the mold cavity like an injection, and then maintaining the pressure until the mold is cooled and a cycle is completed; the operation of the shooting cylinder 2 can pull the head plate fixing assembly 3 to ensure the contact force between the nozzle and the mold; the sliding of the head plate fixing assembly 3 causes the spiral screw to slide, and the sliding of the head plate fixing assembly 3 will not cause the material tube assembly 1 and the melt-glue injection assembly 5 to slide. The front end of the melt-glue injection assembly 5 is set by the head plate fixing assembly 3 and the shooting cylinder 2 to shorten the overall length of the shooting platform. The traditional end plate is used as a fulcrum to install the shooting cylinder 2, which provides pulling force to the reduction box and the motor, changes the traditional driving method, can shorten the length of the shooting platform, and is beneficial to the site layout. At the same time, the tension-driven structure can reduce the probability of deformation of the telescopic rod of the shooting cylinder 2, extend the life of the equipment, and maintain accuracy.
