Vertical cast-aluminum rotor die cutting mechanism

Abstract

The invention discloses a vertical cast-aluminum rotor die cutting mechanism. The vertical cast-aluminum rotor die cutting mechanism comprises a cast-aluminum rotor, a cast-aluminum lower die, first bolts, lower die dragging plates, a lower die base plate, lower die base plate dragging plates, a die-casting melting cup, second bolts, lower die lifting supporting plates, injection heads, a lifting oil cylinder and a pouring gate; the lower die dragging plates are symmetrically arranged on the left side and the right side of the cast-aluminum lower die; the lower die base plate is arranged below the lower die dragging plates, the lower die base plate dragging plates are symmetrically arranged on the left side and the right side of the lower die base plate, and the lower die base plate dragging plates abut against the lower die base plate; the die-casting melting cup is of a cylindrical structure and is used for containing molten aluminum to be cast and formed and symmetrically arranged below the lower die base plate and the lower die base plate dragging plates, and the lower die lifting supporting plates are symmetrically arranged on the left side and the right side of the lower die base plate dragging plates in an abutting-against mode; and the surfaces of the outer side walls of the injection heads abut against the surface of the inner side wall of the die-casting melting cup. According to the scheme, the service life of a vertical cast-aluminum die for a motor rotor can be prolonged, the cost is low, and the quality is good.

Description

technical field [0001] The invention relates to the technical field of tooling and moulds. In particular, it relates to a die-cutting mechanism for a vertical cast aluminum rotor. Background technique [0002] At present, the rotors of small and medium-sized low-voltage motors in China adopt die-casting technology. There are two types of die-casting: horizontal and vertical. Due to the influence of the tonnage of horizontal die-casting equipment and the high price of molds, horizontal die-casting is generally used for small-batch and large-scale rotors. Large batches of small rotors adopt vertical die-casting. [0003] Due to the large diameter of the medium-sized rotor, vertical die-casting is used for rotors with a specification of 250-500mm. Among the existing technicians, the feed rate method of cast aluminum rotor blades is generally used. The feeding area is large, the process is reasonable, and the die-casting quality is relatively high. Good, but due to the harsh w...

Problems solved by technology

[0003] Due to the large diameter of the medium-sized rotor, vertical die-casting is used for rotors with a specification of 250-500mm. Among the existing technicians, the feed rate method of cast aluminum rotor blades is generally used. The feeding area is large, the process is reasonable, and the die-casting quality is relatively high. Good, but due to the harsh working environment, the die-casting lower mold is prone to mold deformation, cracking, short mold life, high management costs, and seriously affects the subsequent production of cast aluminum rotors, affecting the customer's delivery date, and cannot meet the requirements. Large customer demand and tight product delivery requirements
