Description

Flow divider mould

Technical Field

The utility model relates to the technical field of splitter molds, in particular to a splitter mold.

Background

The flow divider is a device connected to the outlet end of the thermostatic expansion valve, and the outlet of the flow divider is connected with a capillary tube and connected with the refrigeration flow of an evaporator in a refrigeration system to provide uniform refrigerant for the evaporator. The existing shunt processing mode is that a blank with a cylindrical head part is obtained after die processing, and then turning processing is carried out on the blank, so that the head part of the blank is changed into a conical shape. This machining method results in a large amount of raw material used and a long time spent for the subsequent turning. Therefore, there is a need to improve existing dies to make the head of the blank conical so that less turning is subsequently required.
