Description
[technical field]
The invention belongs to Design of Dies and manufacture technology field, relate to a kind of integral type planet carrier mould, processing
Method and planet carrier.
[background technology]
Planet carrier is that one of main member of planetary transmission, planet wheel spindle or bearing are just contained in
On planet carrier, integral type planet carrier good rigidly, but if this structure uses solid forging technique, then cut
Cutting processing capacity very big, the most small planet carrier, machining difficulty is bigger, so the most gradually adopting
Replace the planet carrier of metal material with the planet carrier of plastic material, plastics planet carrier needs when being molded the demoulding to adopt
Take the mode loosed core, for there is the integral type planet carrier of the plastic material of three planetary gears when being molded the demoulding
Need the mode taking three faces to loose core.Loosing core in three faces can significantly increase the volume of mould, increases the life of mould
Produce cost, the most also can reduce production efficiency, the most not for having the one of three planetary gears
Body formula planet carrier takes stripping means and the mould that two sides looses core.
[summary of the invention]
The purpose of the present invention is contemplated to solve the problem that prior art exists, it is proposed that a kind of integral type planet
Frame mould, processing method and planet carrier.
The concrete technical scheme of the present invention is as follows:
The present invention provides a kind of integral type planet carrier mould, and described planet carrier is the planet with three planetary gears
Frame, it is characterised in that described mould includes fixed half and moving half, is oppositely arranged two-phase between fixed half and moving half
Interworking merge piece together the first slide block and second slide block with planet carrier die cavity, the first slide block have one or
Multiple wedge shaped projection being set up in parallel, have one first groove in the front end of projection, and the first slide block also has two
Individual second groove, two the second grooves are positioned at the both sides of the end of projection, and described second slide block has one or many
Individual " U-shaped " groove being set up in parallel and match with projection, the rear bottom of described " U-shaped " groove is arc
Shape, described second slide block also has two projections, and said two projection is positioned at the front top of " U-shaped " groove
Both sides, the both sides of " U-shaped " groove and the both sides of projection are plane, the first slide block and the second slide block phase
During chance, described projection inserts in described " U-shaped " groove, and the both sides of described " U-shaped " groove and projection
Both sides tangent, when fixed half and moving half is separated, the first slide block and the second slide block are separated.
Described second slide block and the contact surface relative when meeting of the first slide block are big to the distance of " U-shaped " trench bottom
Radius in planet carrier.
The side that described second groove is relative with projection is arc.
The bottom of described first groove is arc.
The side that described second groove connects with projection is circular arc.
The crowning of described projection is cambered surface.
The present invention also provides for the processing method of a kind of integral type planet carrier, and this planet carrier uses the method for injection to enter
Row processing, it is characterised in that the injection mold of this planet carrier is above-mentioned planet carrier mould, when the demoulding,
First fixed half and moving half is separated, eject one or more planet carriers of injection mo(u)lding the most again with thimble.
The present invention separately provides a kind of integral type planet carrier, and this planet carrier is the planet carrier with three planetary gears,
Including three for installing the external toothing of planetary gear, the ring gear being positioned at planet carrier center and three connection row
The fixing post of carrier upper and lower covers, it is characterised in that first fixes post and second fixes post and have an angular cut,
Two angular cuts are oppositely arranged, and two angular cut place plane convergence lines and the 3rd fix post in the same side.
Two angular cuts are symmetrical arranged, and the both sides of another fixing post are flat mouth corner cut, and first fixes post or second
The plane and the 3rd at the angular cut place of fixing post is fixed post and first and is fixed post or second and fix post together
The tangent plane of the flat mouth corner cut of side is at grade.
The inner side of three fixing posts is all tangent with ring gear, and described first fixes post or second fixes post and the 3rd
The side that fixing post is relative is circular arc.
Useful the having the technical effect that of the present invention
Need three faces to loose core when the present invention is by planet carrier that traditional injection has three planetary gears to make into
The mode loosed core in two sides, on the basis of not affecting the use of planet carrier function, improves the mode that the demoulding is loosed core
After, not only make the volume of mould reduce, cost reduces, but also enables to can hold in single mould
Receive more die cavity, thus disposably can depanning more planetary gear product, production efficiency is greatly improved.
