Manifold block of hot runner system for injection molding

摘要

The present invention relates to a manifold block of a hot runner system for injection molding, and more particularly, heat is applied to the flow portion of the synthetic resin from the injection molding machine to the cavity of the mold to maintain the molten synthetic resin that passes through the resin channel. Comprising a manifold block of the injection molding hot runner system to enable the upper and lower body of the body of the manifold block is formed with a heater installation groove for inserting the rod-shaped electric heater, respectively, In the opening circumference, a cover plate mounting groove for inserting and installing a heater fixing cover plate for fixing the electric heater inserted into the heater mounting groove is formed, and around the cover plate mounting groove, the heater fixing cover plate inserted into the cover plate mounting groove is fixed. By configuring a plurality of screw fastening holes which are respectively fastened to a plurality of cover plate fixing screws to be formed at a predetermined interval In the manufacturing process, the electric heater embedded in the body of the manifold block can be installed more easily, thereby greatly improving the assembly workability, and at the same time, it is possible to quickly and easily replace the electric heater that is disconnected or broken during use. This is to improve the maintainability significantly.;Injection molding, hot runner system, manifold block, electric heater, cover plate, set screw
