Problems solved by technology
[0002] In the process of mold structure design within the scope of injection molding products, due to space limitations, this kind of insert structure usually does not have water cooling in the past, the temperature of the inserts rises quickly, and the rubber around the inserts is difficult to cool, resulting in a long injection molding production cycle and seriously affecting production efficiency; In the past, needles were also used to cool the nozzle, but the nozzle was installed on the side of the formwork, and it was very difficult to install the inner mold.

The invention discloses a nozzle tube cooling needle insert structure. The nozzle tube cooling needle insert structure comprises a water carrying casting insert, a fastening nut, a insert needle, a nozzle tube seat, and a nozzle tube, and the nozzle tube and the water carrying casting insert are provided with central holes; the nozzle tube is connected and fixed on the nozzle tube seat to form a whole; the fastening nut is provided with a connecting cavity, a sinking table and a connecting through hole, the insert needle comprises a butt part and a inserting connecting hole, and the connectingcavity is connected with the butt part in a paired mode to enable the fastening nut and the insert needle to be assembled as a whole; and the nozzle tube penetrates through the nozzle tube seat and is connected inside of the inserting connecting hole, and the nozzle tube seat is installed in the sinking table of the fastening nut. The assembly structure adopts the nozzle tube cooling insert needle structure and further comprises a internal mold and a plate A, the plate A is provided with a water inlet hole, and the center hole of the water carrying casting insert communications with the center hole of the nozzle tube and the water inlet hole of the plate A; the insert needle is fixed to the internal mold by the fastening nut; and the assembly structure has the advantages of simple structure, compact coordination, reasonable design, and elegant appearance.
Description
【Technical field】 [0001] The invention mainly relates to an insert structure for nozzle cooling and an assembly structure using the same. 【Background technique】 [0002] In the process of mold structure design within the scope of injection molding products, due to space limitations, this kind of insert structure usually does not have water cooling in the past, the temperature of the inserts rises quickly, and the rubber around the inserts is difficult to cool, resulting in a long injection molding production cycle and seriously affecting production efficiency; In the past, needles were also used to cool the nozzles, but the nozzles were installed on one side of the formwork, and it was very difficult to install the inner mold. In order to improve the efficiency of injection molding production and mold loading efficiency, it is urgent to design an optimized nozzle cooling insert structure. 【Content of invention】 [0003] In order to solve the above problems, the present in...
