Problems solved by technology

[0002] At present, the hot nozzle bushing in the prior art is directly pressed on the hot nozzle pad. Because the hot nozzle pad has a large diameter and a large contact area, it will not sink into the manifold, but the main body is in direct contact with the manifold, and the contact area is smaller than Hot nozzle pads, the hardness of the manifold is smaller than that of the nozzle bushing, and the nozzle bushing will sink into the manifold, resulting in glue leakage in the system

Abstract

The invention discloses a disk spring hot nozzle bush. The disk spring hot nozzle bush comprises a hot nozzle bush body. One end of the outer wall of the hot nozzle bush body is provided with a shaft shoulder, and the other end of the outer wall of the hot nozzle bush body is provided with a clamping groove. A clamp spring is arranged in the clamping groove. A spring and a pressure-bearing gasket are arranged on the outer wall of the hot nozzle bush body and located between the shaft shoulder and the clamping spring. The hot nozzle bush body is arranged in a die mounting hole. A hot nozzle body is arranged in the hot nozzle bush body. The shaft shoulder, the spring and the pressure-bearing gasket are arranged between the hot nozzle bush body and the die mounting hole. In this way, the disk spring hot nozzle bush can play a role in protecting a die and a hot runner system against glue leakage; the bearing capacity is large; pressurization is uniform; the buffer capacity and damping capacity are high; the contact area is small; heat loss of a hot nozzle is small, and energy resources are saved; the hot runner system is good in stability.

Description

technical field [0001] The invention relates to the improvement of a hot nozzle bushing, in particular to a bushing that can protect the mold and the hot runner system and avoid glue leakage; has a large bearing capacity; uniform pressure; strong buffering and shock absorption capabilities; small contact area ; The heat loss of the hot nozzle is also less, saving energy; the stability of the hot runner system is good for the disc spring hot nozzle bushing. Background technique [0002] At present, the hot nozzle bushing in the prior art is directly pressed on the hot nozzle pad. Because the hot nozzle pad has a large diameter and a large contact area, it will not sink into the manifold, but the main body is in direct contact with the manifold, and the contact area is smaller than The hardness of the hot nozzle pad and the manifold is smaller than that of the hot nozzle bushing, and the hot nozzle bushing will sink into the manifold, resulting in glue leakage in the system. ...
