Abstract

The invention provides a rubber stator forming fixture and a rubber stator forming process and overcomes the defects of complex glue-injection process and inaccurate stator forming size in the prior art caused by restoration of a glue injection port after glue is injected into a stator of a screw pump. The rubber stator forming fixture provided by the invention comprises a fixture, a mold core, a metal steel sheath and rubber, wherein the fixture is arranged at two ends of the mold core; the metal steel sheath is arranged on the periphery of the mold core; the rubber is filled between the metal steel sheath and the mold core; and an opening is horizontally formed in one end of the metal steel sheath. The process is simple in steps, the stator size is accurate and the phenomenon of material leakage generated in the running course of the screw pump is avoided.

Description

technical field [0001] The invention relates to a stator, in particular to a rubber stator forming jig and a rubber stator forming process. Background technique [0002] The screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and the screw to deliver or pressurize the liquid. [0003] The screw pump stator is an important part that is easily damaged in the screw pump. Its dimensional accuracy and molding process affect the service life of the rubber stator. The existing screw pump stator has a rubber stator molding fixture 1A such as figure 1 As shown, it adopts the vertical glue injection process. During the vertical glue injection, it is necessary to open the injection hole 3A in the middle of the steel sleeve 2A, so under the high pressure injection, the mold core 4A is prone to deformation, so the molding size of the stator is not accurate; In addition, in order to avoid leakage of materials during the o...
