AI Technical Summary
Technical Problem
During the injection molding process of PET foam sheets, the gap between the template hinge connecting pin and the pin hole increases, leading to lubricant leakage and dry friction, which reduces the service life of the connecting pin.
Method used
A template hinge base was designed, comprising a base plate, a pin support, an oil storage assembly, and a connecting pin. The oil storage assembly stores lubricating oil and applies lubricating oil when the connecting pin is under stress, thereby reducing the probability of oil leakage and dry friction.
Benefits of technology
It effectively reduces the probability of oil leakage on the surface of the connecting pin inside the template hinge seat, increases the service life of the connecting pin, and reduces wear.

Abstract
The utility model relates to the technical field of injection molding machines, and particularly discloses a template hinged support for reducing oil leakage during injection molding of a PET foamed sheet, which comprises a bottom plate, a pin support, an oil storage assembly and a connecting pin, the bottom plate is detachably connected to the template; the pin support is fixedly connected to the side, away from the formwork, of the bottom plate, and a pin hole is formed in the pin support. The oil storage assembly is arranged in the pin hole and used for storing lubricating oil. The connecting pin rotatably penetrates through the pin hole, and the side wall of the connecting pin slidably abuts against the hole wall of the pin hole and the oil storage assembly. The mold plate hinge seat has the effects that the probability of dry grinding caused by oil leakage on the surface of the connecting pin in the mold plate hinge seat during injection molding is reduced, and the service life of the connecting pin is prolonged.
