Abstract
The utility model relates to a magnetic ring automatic mould for producing a permatron, which belongs to the field of a manufacturing forming mould. The magnetic ring automatic mould is composed of a mould frame, a mould die cavity, a mould former block, a core bar and a hydraulic charging system and is characterized in that an axial center deep hole is arranged in the core bar to be used as a feed pipeline, the place of the core bar having a proper distance from the top end is provided with a radial through hole charging hole which is communicated with a feed pipeline, the lower part of the core bar is provided with a feed hole connected with the tail end of the feed pipeline, and the feed hole is communicated with the hydraulic charging system. The utility model has concise and scientific structure, integrates the feed hole and the feed pipeline at the core bar, realizes the full automation of the magnetic steel product compacting process, not only shortens the compacting time, greatly enhances the production efficiency, and reduces the labor intensity of workers, but also has accordant product density and size as well as stable and accordant product magnetic property due to constant feeding amount, enhances the rate of finished products, and prolongs the service life of the mould, thereby remarkably increasing the economic benefit.
Description
Technical field
The utility model is used to produce the magnet ring automatic die, belongs to manufacturing industry mould field, particularly the automatic die of moulding magnet steel product.
Background technology
The current mould that is used to produce magnet ring comprises mould bases, mold cavity 9, core bar 1, mold and punching head 8 is formed, during production, mold and punching head is motionless, and following oil cylinder rises, mold cavity, core bar is up, mold cavity and core bar are partly formed add material space K, to add material space K reinforced after, the mould closure, upper and lower mould is exerted pressure simultaneously, extrude the moisture content in the raw material, take away with negative pressure, after hydraulic press reaches rated pressure, keep opening mould behind the certain hour, drift is motionless, following oil cylinder return, mold cavity, core bar is descending, makes mold cavity, core bar partly with drift in same level, goods are taken out in the goods demoulding.Is the key issue that adopts existing mold to realize that auto feed is produced: how charging? what parts is charging aperture located at? how reinforced to adding material space? what position is this located to charge door again? because these problems do not solve, so, so far the production method that is still this backwardness of hand charge that most of producers adopt, promptly adopt manual operations that the oar material is inserted and add material space, again that die surface is unnecessary raw material is removed.This charging process not only efficient is low, labor strength is big, and forming process can only be semi-automatic, but also exists such as the moulded products density unevenness even, size is inconsistent, during sintering because of the inconsistent problems such as causing waste product that cracks or ftracture of each position coefficient of expansion of product.Therefore, the automatic feed that solves this area mould realizes that with reinforced automated production becomes the major issue of paying close attention in the industry.
The utility model content
The purpose of this utility model provides a kind of automatic die that is used to produce magnet ring.
The utility model purpose is achieved by the following technical solution:
Originally be used to produce the automatic die of magnet ring, comprise mould bases, mold cavity, mold and punching head, core bar, characteristics are that to offer the axial centre deep hole in core bar 1 be feeding pipe 2, height with the processing magnet ring is a foundation, at core bar 1 apart from its respective distance place, top, offer radial direction through hole charge door 3 with feeding pipe 2 UNICOMs, offer in core bar 1 bottom and the feeding pipe 2 terminal charging apertures 4 that are connected, charging aperture 4 is by check valve 5 and press hydraulic pressure material feeding charging system S UNICOM, between the endoporus of mold and punching head 8 and core bar 1 sealing cowleather ring 6 is housed.
The design is with automatically feed charging aperture, charge door and feeding pipe all design on these parts of core bar, offer the axial centre deep hole as feeding pipe in core bar inside, height with the processing magnet ring is a foundation, at core bar apart from its respective distance place, top, the radial direction through hole of offering with feeding pipe UNICOM is a charge door, have and the terminal charging aperture that is connected of feeding pipe in the core bar bottom, charging aperture is then by check valve 5 and press hydraulic pressure material feeding charging system S UNICOM, thereby realized throat-fed by the core bar bottom, by the feeding pipe feeding of core bar inside, from the charge door on feeding pipe top to the reinforced auto feed process in mould charge space.
When hydraulic pressure material feeding charging system is reinforced, mold and punching head is motionless, mold cavity, core bar uplink synchronization, between mold cavity and core bar, form the charge space, close die, press material feeding system passes through the feeding pipe charging of the charging aperture of core bar bottom to the core bar center, from the charge door at its top to the charge space of mould automatic-feeding, reinforced finishing, mold and punching head is motionless, mold cavity and core bar are descending at the pressure of patrix, are sealed the build-up pressure process that is pressed in the die cavity by the mold and punching head endoporus until charging aperture.
The utility model is simple for structure, science, stable, compile charging aperture, feeding pipe, charge door in core bar parts one, adopt the design's mould molding, realized that magnet steel product compression moulding process is full-automatic, not only shorten the compression moulding time, increase substantially production efficiency, reduce labor strength, and because of the feeding quantity of product is constant, product density, consistent size, product magnetic property stable and consistent, improve the finished product rate, die surface totally cleans, and prolongs die life, so the economic benefit of significantly improving.

The specific embodiment
How now further specify the utility model in conjunction with the accompanying drawings operates:
The design offers the axial centre deep hole as feeding pipe 2 in core bar 1 inside, at core bar 1 apart from 30mm place, its top, the radial direction through hole of offering with feeding pipe UNICOM is a charge door 3, have and the feeding pipe 2 terminal charging apertures 4 that are connected in the core bar bottom, charging aperture 4 is by check valve 5 and press hydraulic pressure material feeding charging system S UNICOM, to prevent that slip from refluxing, thereby charging aperture 4 chargings have been realized by core bar 1 bottom, by feeding pipe 2 feedings of core bar 1 inside, from the charge door 3 on feeding pipe 2 tops to the reinforced auto feed process in mould charge space.
The design's core bar is size and processing technology processing in accordance with regulations, for guaranteeing the intensity of core bar, inlays the bag carbide alloy outside core bar, for improving the wearability of sealing ring, between drift endoporus and core bar sealing cowleather ring is housed.
The utility model mold cavity product is not limited by specification.
