Shut-off synchronous glue sealing nozzle

Abstract

The invention discloses a shut-off synchronous glue sealing nozzle. The nozzle comprises a nozzle middle seat and a power assembly arranged on the outer side of the nozzle middle seat and arranged inthe same direction as the nozzle middle seat, wherein a glue injection runner is formed in the nozzle middle seat in the axial direction of the nozzle middle seat, a glue sealing cavity communicatingwith the glue injection runner is formed in the nozzle middle seat in the radial direction of the nozzle middle seat, a glue sealing valve element is movably arranged in the glue sealing cavity, the bottom end of the glue sealing valve element is connected with the power assembly, and the top end of the glue sealing valve element is driven by the power assembly to enable the glue injection runnerto be unblocked or blocked. According to the shut-off synchronous glue sealing nozzle, a lever is adopted to push the glue sealing valve element to block flowing of molten plastic in the runner, so that the problem that glue is prone to overflowing during glue melting of an injection molding machine is solved, the product quality can be improved, the production stability can be improved, a production period can be obviously shortened, and the injection molding machine can simultaneously carry out other actions such as mold opening, ejection and mold closing while carrying out glue melting.

Description

technical field [0001] The invention relates to a nozzle of an injection molding machine, in particular to a flow-cutting and synchronous sealing nozzle. Background technique [0002] Injection molding products are widely used in all walks of life. With the continuous improvement of people's living standards, the injection molding industry is constantly innovating and improving in the process of development. While improving the quality of products, it is also necessary to reduce production costs accordingly. As the main molding method of plastic products, injection molding is characterized by high production efficiency, strong adaptability to various plastics, and the ability to form injection molded products with complex shapes and precise dimensions. It is widely used in defense industry, aviation, transportation, electrical, Various fields such as machinery, construction, agriculture, culture and education. [0003] The current injection molding process is generally carr...
