Description

Technical Field

[0001] The utility model belongs to the technical field related to the injection molding of hemodialyzers, and particularly relates to a heating structure for multi-stage injection molding of hemodialyzers. Background Technique

[0002] A hemodialyzer is a pipeline and container for solute exchange between blood and dialysate, and is a key part of hemodialysis. The dialyzer mainly consists of a support structure and a dialysis membrane. The latter is an important component and is a semi-permeable membrane that only allows molecules smaller than the membrane pore size to pass through. Therefore, when producing hemodialyzers, injection molding equipment is required, and in order to ensure the stability of the injection molding process, a heating structure needs to be installed on the injection molding equipment.

[0003] However, when existing multi-stage injection molding equipment uses a heating structure, most of them install multiple heating structures on the equipment to perform multi-point heating on the injection molding process. However, this method uses more heating equipment, resulting in waste of resources. At the same time, the heating structures used do not have the ability to adjust the position according to the different injection molding points. Therefore, each time an adjustment is made, connecting pipes of different lengths need to be replaced. At the same time, since the connecting pipes used cannot be arbitrarily changed in shape, there is a situation where the injection molding equipment may cause wear or extrusion to the connecting pipes. For this reason, we provide a heating structure for multi-stage injection molding of hemodialyzers to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a heating structure for multi-stage injection molding of hemodialyzers. By connecting the interiors of the first semi-circular frame and the second semi-circular frame, multi-stage heating of multi-stage injection molding is achieved. At the same time, the use of the corrugated hose can be adjusted according to the shape environment between the first semi-circular frame and the second semi-circular frame.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0028] Specifically, there are two semi-cylindrical half-frames 1 and two semi-cylindrical half-frames 2; heating pipes 4 are fixed inside both of the two half-frames 1, and a plurality of annularly and evenly arranged first through pipes 102 are fixed on the front end faces of the half-frames 2.

Corrugated hoses 3 are arranged between the first through pipes 102 and the second through pipes 202 with the same front-back direction. Connecting pipes 301 are fixed at both ends of the corrugated hoses 3, and the other ends of the connecting pipes 301 are bolted to the ends of the first through pipes 102 and the second through pipes 202 through flange plates 302.
