The technical scheme that adopts is:
high-precision dual reset beveled wheel mold device comprises stationary mould for mould and mould dynamic model, and stationary mould for mould comprises: fixed clamping plate, stripper plate, solid plate and cover half die cavity, the mould dynamic model comprises: moving clamping plate, square iron, backing plate, moving platen and dynamic model mold cavity component that screw is fixing, and installing dynamic model guide pillar on moving platen, the dynamic model guide pillar is installed in the guide pin bushing of solid plate, at fixing end needle plate and the face needle plate of the inboard installing of square iron screw, and installing push pipe, the fixing associated components such as cover half die cavity mold insert and bearing external member on solid plate, the corresponding associated components such as dynamic model die cavity mold insert and bearing external member orientation angle wedge that install additional on moving platen, the installing corresponding to the cover half mold insert of dynamic model mold insert, matched moulds forms later on the helical gear die cavity of high-precision dual reset, the large guide pillar of installing on fixed clamping plate, large guide pillar is installed on stripper plate, solid plate, square iron, in backing plate and moving platen, install sprue puller on stripper plate, installing sprue bush and locating ring on fixed clamping plate.Fixing limited block on the face needle plate.Establish orientation angle wedge and double-deck die cavity on the dynamic model die cavity, match with bearing between internal layer and outer die cavity, the outer inside of overlapping is provided with around the spiral cooling water channel.
Advantage of the present utility model:
This die device can be produced the high-precision dual reset helical gear product of variety classes and precision simultaneously, and the design accuracy that every kind of helical gear engagement degree can meet or exceed product requires (more than the Pyatyi precision), and the forming stability of product improves greatly simultaneously.The air discharge duct of cover half mold insert and dynamic model mold insert and cooling water channel design greatly reduce the moulding difficulty of product, have avoided some formed product defectives.As: exhaust is bad, fill bad, the overproof undesirable condition that waits of engagement degree.Reduce the cycle of formed product, improved the product working (machining) efficiency.
Description of drawings:
Accompanying drawing 1 is mould structure schematic diagram of the present utility model.
The specific embodiment:
High-precision dual reset beveled wheel mold device comprises stationary mould for mould, mould dynamic model and mold cavity.
Stationary mould for mould comprises: fixed clamping plate 1, stripper plate 2, solid plate 3, cover half mold cavity component 10.
The mould dynamic model comprises: moving clamping plate 9, square iron 6, backing plate 5, moving platen 4, dynamic model mold cavity component 11.
Installing dynamic model guide pillar on mould moving platen 4.The dynamic model guide pillar is installed in the guide pin bushing of solid plate 3.
At fixing end needle plate 8 and the face needle plate 7 of the inboard installing screw of square iron 6, and the installing push pipe.
In the accurate fixedly cover half mold cavity component 10 of solid plate 3.Accurate fixedly dynamic model mold insert and the bearing external member of correspondence on moving platen 4.Mould dynamic model mold insert and bearing external member and the corresponding installing of cover half mold insert and bearing external member, matched moulds forms later on the helical gear die cavity of high-precision dual reset.
The large guide pillar of installing on fixed clamping plate 1, large guide pillar is installed in stripper plate 2, solid plate 3, square iron 6, backing plate 5 and moving platen 4.
Install sprue puller on stripper plate 2, installing cone-shaped gate cover and locating ring on fixed clamping plate 1.Fixing ejecting limit block on face needle plate 7.
Offer around the spiral water route on stationary mould for mould mold cavity component 10 and dynamic model mold cavity component 11, connect outside die temperature control device, play to the mold cavity heat radiation and keep the constant effect of mold temperature.Offer air discharge duct on cover half mold cavity component 10 and dynamic model mold cavity component 11.
The die cavity that forms after stationary mould for mould mold cavity component 10 and mould dynamic model mold cavity component 11 matched moulds can be the die cavity of identical gear or the die cavity of different gear, and precision can meet or exceed the Product Precision requirement fully.
Its operation principle is:
Stationary mould for mould is installed on forming machine by tools such as pressing plates by fixed clamping plate 1, it realize by locating ring and forming machine between the location and spacing.Stripper plate 2 and solid plate 3 can be in the large enterprising line slips of guide pillar, and solid plate 3 is partly realized positioning and guiding by dynamic model guide pillar and dynamic model.The mould dynamic model is arranged on the drawer at movable side of forming machine by tools such as pressing plates by dynamic model installing plate 9, end needle plate 8 and face needle plate 7 form liftout attachment, realize the ejection device action under the thick stick effect of the top of forming machine.
During die sinking, drawer at movable side at forming machine retreats, first will expect throwing off, then solid plate 3 and moving platen 4 are separately, cover half rotation under the guiding of bearing and dynamic model orientation angle wedge is deviate from the upper strata profile of tooth, after the drawer at movable side of forming machine stops, ejecting mechanism begins to eject action, this moment, product ejected in driven model cavity 11 under the effect of push pipe, so because die cavity is that the helical teeth structure has produced horizontal revolving force in the process that ejects, the rotation under the guiding of bearing of profile of tooth mold insert this moment can be ejected product normally by push pipe.After product ejected, the mould matched moulds began next molding cycle, and during matched moulds, cover half is in the guiding Regression home position of bearing and dynamic model orientation angle wedge.This Mould Machining is easy, and during production, stability is with safe, and Product Precision can reach more than 5 grades, is fit to scale of mass production.
