Abstract
The utility model belongs to the technical field of lost foam molds, and provides a side core-pulling mechanism of a lost foam mold of a motor casing. The side core-pulling mechanism of the lost foam mold of the motor casing comprises side core-pulling inserts (1) and core-pulling air cylinders (2); the side core-pulling inserts used for molding of cooling fins on the periphery of the motor casing are four in number and are evenly distributed along the circumferential direction, and the four side core-pulling inserts (1) are located in an inner cavity of a lower mold air chamber (3); the core-pulling air cylinders (2) are four in number and are installed respectively in correspondence with the side core-pulling inserts (1); the four core-pulling air cylinders (2) are respectively fixed on the outside of the lower mold air chamber (3); and the side core-pulling inserts (1) are respectively connected with pistons of the corresponding core-pulling air cylinders (2) through guide posts. The side core-pulling mechanism of the lost foam mold of the motor casing improves molding efficiency, reduces labor intensity of workers, lowers production cost, ensures consistency of molding, and has the advantages of being simple in molding operation, good in product consistency, high in foam pattern accuracy, and good in molding effect.
Description
Technical field
The utility model belongs to the evaporative pattern mold technical field, mainly proposes a kind of side core-pulling mechanism of motor casing evaporative pattern mold.
Background technology
Motor casing adopts the difficult point of lost foam casting process to be: (wall thickness of fin is generally at 2.5-5mm for the fin around the motor casing, exceed outer round surface 30-60mm) casting, the middle same circularity that stator surface is installed guarantees, the processing of the uniform wall thickness of interior profile, lost foam casting difficult point based on above motor casing is analyzed, the design main points of the evaporative pattern mold of motor casing are mainly reflected in motor casing product all around somatotype, processing, the mold insert material selection of fin, and mould is realized opening in advance filling material.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is the side core-pulling mechanism that proposes a kind of motor casing evaporative pattern mold, makes that it has that forming operation is simple, good product consistency, Foam Pattern precision are high, the characteristics of good forming effect.
The utility model adopts following technical scheme for finishing above-mentioned purpose:
A kind of side core-pulling mechanism of motor casing evaporative pattern mold, described side core-pulling mechanism comprise the side core-pulling mold insert and the cylinder of loosing core; Side core-pulling mold insert in order to fin around the moulding motor casing is four that are uniformly distributed along the circumference, and four described side core-pulling mold inserts are arranged in the inner chamber of counterdie air chamber; The described cylinder of loosing core is four, the respectively respective side mold insert setting of loosing core; Four described cylinders of loosing core are separately fixed at the outside of counterdie air chamber; Described side core-pulling mold insert respectively by guide pillar with the piston of the corresponding cylinder of loosing core connect, consists of four described side core-pulling mold inserts under the effect of four cylinders of loosing core, inwardly the structure of the closed formation of motion mold cavity.
The side core-pulling mechanism of a kind of motor casing evaporative pattern mold that the utility model proposes, adopt above-mentioned technical pattern, improved shaping efficiency, labor strength and production cost have been reduced, guaranteed the uniformity of moulding, had that forming operation is simple, good product consistency, Foam Pattern precision are high, the characteristics of good forming effect.
