Description

A kind of multiple tooth shape mixing gear die

Technical field

The utility model belongs to Gear Production technical field, and in particular to a kind of multiple tooth shape mixing gear die.

Background technology

Limited by Gear Processing Tool and Die Technology, current gear product be generally monodentate shape or bidentate shape compared with More, the gear product of three tooth forms even four tooth forms is relatively fewer.This is because gear mesh required precision is higher, especially gear The concentricity of degree of engagement, central shaft and gear ring is the core pith of gear product.But some current existing gear dies The problems such as tool, Template Location precision is not high before and after generally existing, each tooth form mold insert and the poor concentricity in product center hole, and Any cooling provision is not often taken on traditional gear die mold insert, or directly using the type of cooling of watering, cooling effect It is bad, so as to cause product deformation it is larger the problems such as.Therefore the more tooth-profile of gear produced cannot be satisfied required precision, it is necessary to It is replaced using multigroup monodentate shape or bidentate type gear, has not only increased the cost and its assembling space of product, but also may be more One group of Gearing.

Utility model content

In view of the above problems, the utility model has been intended to provide a kind of multiple tooth shape mixing gear die.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：

A kind of multiple tooth shape mixing gear die, is made of openable and closable front die component and back die component；The front die component Including one piece of upper mounted plate, the lower surface of fixed plate is provided with one piece of front template, the preceding mould by one piece of water gap plate It is embedded in the middle part of plate there are one mould mold insert before first, mould mold insert before being embedded with second in mould mold insert before described first, described second Mould mold insert before third is embedded in preceding mould mold insert；The back die component includes one piece of bottom plate, the upper table of the bottom plate Face is fixed with one piece of support plate by support block, and the upper surface of the support plate is provided with one piece of rear pattern plate, in the rear pattern plate Portion is embedded there are one rear mold mold insert corresponding with mould mold insert before described first, and the top of the rear mold mold insert is arranged that there are one tiltedly Tooth mold insert, setting is there are one bearing between the helical teeth mold insert and the rear pattern plate, after being provided with one in the rear mold mold insert The lower end of mould pin, the rear mold pin is inserted into the support plate；The front template, the rear pattern plate and the support plate It is respectively arranged on lateral wall and mould mold insert, the rear mold mold insert and the rear mold pin are connected to before described first cooling water Road.

Further, mould mold insert, the rear mold before mould mold insert, the third before mould mold insert, described second before described first Mold insert, the helical teeth mold insert and the rear mold pin are concentric.

Further, the lower surface of mould mold insert is flushed with the lower surface of the front template before described first, before described second The lower surface of mould mold insert is higher than the lower surface of mould mold insert before described first, and the lower surface of mould mold insert is higher than described the before the third The lower surface of mould mold insert before two.

Further, the upper surface of the helical teeth mold insert and the bearing is flushed with the lower surface of the rear pattern plate.

Further, the upper end of the rear mold pin is higher than the lower surface of the rear pattern plate, when the front die component and institute When stating back die component molding, the upper end of the rear mold pin is convex into mould mold insert before described first.

Further, the top outer rim of the rear mold mold insert and the lower internal edge of the helical teeth mold insert take 5 ° of wipings to wear fixed Position.

Further, one piece of Ejector Retainer Plate, the Ejector Retainer Plate are provided between the bottom plate and the support plate Lower surface be fixedly connected with the bottom plate, the upper surface of the Ejector Retainer Plate is provided with one piece of thimble panel.

Further, the lower surface of the front template and the upper surface of the rear pattern plate are provided with the fine positioning worked in coordination Block.

The beneficial effects of the utility model are as follows：

The utility model uses common Three-board-mould structure, it is contemplated that the preceding mould of gear product has two circle tooth forms, therefore this mould Tool in front template has done three mold inserts, allows these three preceding mould mold inserts to work in coordination positioning, is cut out with ensuring that tooth form can be cut by line, guarantor The machining accuracy of tooth form is demonstrate,proved.In view of the rear mold of gear product is helical teeth, therefore helical teeth is done on the rear pattern plate of this mold Mold insert and rear mold mold insert, and positioning is worn using 5 ° of wipings, to ensure that helical teeth mold insert line cuts tooth form.Helical teeth mold insert periphery is bearing, mould When tool die sinking ejection, helical teeth mold insert is rotated by bearing, the smooth depanning of gear product.In view of there is a hole among gear product, Therefore the pin that one can go deep into preceding mould mold insert is added in rear pattern plate, and each tooth form and product are ensured with mould mold insert before and after positioning The concentricity of centre bore.This mold takes the mode of the directly cooling front and back mould mold insert of cooling water channel, to reach preferably cooling effect Fruit effectively controls the deformation extent of product.In conclusion the utility model efficiently solves three tooth forms or four tooth form teeth Wheel product goes out modulus problem, avoids gear product separating use, not only solve the cost and assembling space of product, also subtract Transmission problem hidden danger caused by more one group of gear product is lacked.
