,Described cover half partly comprises: fixed clamping plate, stripper plate, solid plate and cover half mold cavity component, described dynamic model partly comprises: moving clamping plate, square iron, backing plate, moving platen and dynamic model mold cavity component that screw is fixing are equiped with the dynamic model guide pillar on moving platen.The dynamic model guide pillar is located 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 the installing push pipe; Fixing cover half die cavity mold insert on solid plate.The corresponding dynamic model die cavity mold insert that installs additional on moving platen.Dynamic model die cavity mold insert and the corresponding installing of cover half die cavity mold insert, matched moulds forms later on the helical gear die cavity of precise plastic.The large guide pillar of installing on fixed clamping plate, large guide pillar is installed in stripper plate, solid plate, square iron, 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 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.
plastic beveled wheel mold of the present utility model adopts the multi-point sprue injection molding technology, adopt the auxiliary extrusion technique by force of bearing holder (housing, cover) during product stripping, mould adopts around die cavity examination exhaust technique, mould adopts die cavity spiral surrounding cooling water technology, Mould Machining adopts die cavity one discharge precision processing technology, can produce the precise plastic helical gear product of variety classes and precision by mass simultaneous, and every kind of helical gear engagement degree can meet or exceed the required precision (more than the Pyatyi precision) of metal product of the same race, the forming stability stated in the use in mould production of this product can improve 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
Fig. 1 is mould structure schematic diagram of the present utility model.
The specific embodiment:
A kind of precise plastic beveled wheel mold comprises cover half, dynamic model.Cover half comprises: cover half installing plate 1, stripper plate 2, solid plate 3, cover half mold cavity component 10.Dynamic model comprises: dynamic model installing plate 9, square iron 6, backing plate 5, moving platen 4, dynamic model die cavity mold insert 11.Installing dynamic model guide pillar on 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.At the accurate fixedly cover half die cavity mold insert 10 of solid plate 3.Be fixed with dynamic model die cavity mold insert 11 and the corresponding installing of cover half die cavity mold insert 10 on moving platen 4, matched moulds forms later on the helical gear die cavity of precise plastic.The large guide pillar of installing on cover half installing 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 cover half installing plate 1.Fixing ejecting limit block on face needle plate 7.Offer around the spiral water route on stationary mould for mould die cavity mold insert 10 and dynamic model die cavity mold insert 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 die cavity mold insert 10 and dynamic model die cavity mold insert 11.The die cavity that forms after stationary mould for mould die cavity mold insert 10 and mould dynamic model die cavity mold insert 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:
Gear material adopts polyformaldehyde (POM) at tensile strength, bending strength, endurance life, and wearability and electrically all very good has very low coefficient of friction and good geometrical stability, is particularly suitable for making gear and bearing.POM be in plastic material mechanical property near metal, and one of the kind of alternative metal.Use aborning die device to produce the precise plastic helical gear product of variety classes and precision by mass simultaneous after this product improvement, and every kind of helical gear engagement degree can meet or exceed the required precision (more than the Pyatyi precision) of metal product of the same race, and the forming stability stated in the use in mould production of this product can improve greatly simultaneously.
Stationary mould for mould is installed on forming machine by tools such as pressing plates by cover half installing 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, after the drawer at movable side of forming machine stopped, ejecting mechanism began to eject action, and this moment, product ejected in driven model cavity 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.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.
