Abstract

The invention provides a spiral rotor mold. The spiral rotor mold comprises an inner core, wherein the outer wall of the inner core is sleeved with a medium sand box, a gap between the inner core andthe medium sand box is filled with precoated sand, and the outer perimeter of the upper portion of the inner core is larger than that of the lower portion of the inner core; a spiral groove is formedin the outer wall of the upper portion of the inner core, and a first through hole is longitudinally formed in the inner core; a bottom plate is fixedly arranged below the inner core, a second throughhole is formed in the middle of the bottom plate, and a vibration pump is arranged at the bottom of the bottom plate; and the lower portion of the inner core penetrates through the second through hole. The spiral rotor mold further comprises a heating pipe, and the lower portion of the heating pipe penetrates through the first through hole and then is fixedly connected with the lower portion of the inner core. The spiral rotor mold has the advantages of being simple in structure, good in demolding effect and capable of saving the cost, and is suitable for the field of spiral rotors.

Description

technical field [0001] The invention relates to the technical field of helical rotors, in particular to a helical rotor mold, a demoulding device and a preparation method thereof. Background technique [0002] The screw rotor is one of the important components in the air compressor, and its preparation method and equipment will directly affect the performance of the air compressor. [0003] The traditional screw rotor usually turns the bar, and then slowly mills the spiral groove on the outer wall of the turned bar to complete the processing of the screw rotor. The preparation method is complicated, and a large amount of manpower and raw materials are wasted; the machine tool is also easily worn during the processing, and the cost is high. [0004] In order to solve the problems of complex preparation methods, waste of manpower and raw materials, serious wear and tear of machine tools and high cost, someone provided a spiral rotor mold with spiral grooves on the outer wall ...
