Embodiment Construction

[0017] combine Figure 1 to Figure 3 , which describes the specific implementation of the present invention in detail, but does not limit the claims in any way.

[0018] An integral hot runner assembly process of the present invention includes a diverter plate 100, and a plurality of diverter holes 101 are arranged on the diverter plate 100, and the size of the diverter holes 101 is equal to or slightly smaller than the hot nozzle 200; The hole 101 is circular, and correspondingly, the hot nozzle 200 is also circular, and the inner diameter of the distribution hole 101 is slightly smaller than the outer diameter of the hot nozzle 200; Thermal expansion, insert the hot nozzle 200 into the distribution hole 101 of the distribution plate 100 . During implementation, the temperature of the splitter plate can be adjusted at a temperature above 100°C according to actual needs. During implementation, a guide hole 300 is provided on one side of the diversion hole 101, and a guide gr...

Abstract

The invention provides an integrated hot runner assembly process. The technical purpose is to provide an assembly process of an integrated hot runner system with simple process, tight matching and precise assembly. The integrated hot runner assembly process comprises a splitter plate; a plurality of splitter holes are formed on the splitter plate; the sizes of the splitter holes are slightly less than those of hot nozzles; the splitter plate is heated to a temperature more than 100 DEG C in an assembly process; the splitter holes on the splitter plate are subjected to hot expansion; and the hot nozzles are inserted in the splitter holes of the splitter plate. With the adoption of the integrated hot runner assembly process provided by the invention, the better sealing property is achieved; no glue leakage is ensured because the splitter plate is matched with the hot nozzles; and a hot runner structure has a longer service life, and is safer and more reliable to use. The integrated hot runner assembly process is applicable to be applied in the hot runner structure of a die.

Description

technical field [0001] The invention relates to a production process of a hot runner, in particular to an integral hot runner assembly process. Background technique [0002] In the prior art, in the hot runner structure, the fluid in the manifold passes through the channel of the manifold and flows out through the hot nozzle. The requirements for the matching process of the hot nozzle and the manifold in the hot runner technology are very strict, and the existing In the technology, there is a lack of a good assembly process in the size matching and operation process, resulting in local glue leakage or shortening the service life of the product due to poor installation and process; the assembly process of the hot runner manifold and the hot nozzle in the prior art Existing technical defect becomes the technical problem urgently to be solved by those skilled in the art. Contents of the invention [0003] The technical purpose of the present invention is to overcome the tech...
