Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these examples are merely to illustrate this
It invents rather than limits the scope of the invention, after the present invention has been read, those skilled in the art are to of the invention various
The modification of equivalent form falls within the application range as defined in the appended claims.
A kind of injection molding die craft equipment of gear shapping machine internal spline guide rail plastic coating, as shown in Figure 2-5, including pedestal 1, lower cover
2, positioning seat 3, internal tooth die cap 4, upper press cover 5, main shaft 6, in which:
The pedestal 1 is for placing internal spline guide rail 7 to be molded.
The lower cover 2 and internal spline guide rail 7 to be molded are fixed.Kidney slot 21, the waist are provided on the lower cover 2
Shape hole 21 and injection molding through-hole 31 correspond.
The positioning seat 3 is fixed on 6 bottom of main shaft, and the positioning seat 3 is located at the top of lower cover 2.The positioning seat 3
On open up there are two through-hole 31 and 4 positioning hole 33 is molded, offer cast gate 32, the cast gate on the injection molding through-hole 31
32 are located at close to the part that injection molding through-hole 31 is molded.The positioning seat 3 of stating is fixed by screws on 6 bottom of main shaft.
The upper press cover 5 is nested on main shaft 6, and 5 lower part of upper press cover is pressed into internal spline guide rail 7 to be molded, and institute
Upper press cover 5 is stated to be fixedly connected with internal spline guide rail 7 to be molded.
4 sets of the internal tooth die cap is located at the lower section of upper press cover 5 on the spline of main shaft 6.
The internal tooth die cap 4, main shaft 6, positioning seat 3 and internal spline guide rail 7 to be molded form injection molding space.
Shooting Technique of the invention is as follows:
As shown in Fig. 2, pedestal 1 mainly plays a supportive role, internal spline guide rail 7 is placed on pedestal 1, by internal spline guide rail
7 empty, and facilitate subsequent installation positioning seat 3 and lower cover 2, and bottom end hollow out also provides space for subsequent injection molding.
4 sets of internal tooth die cap are inserted in internal spline guide rail 7 on the spline of main shaft 6, then by main shaft 6, main shaft bottom is with 4
The hexagon socket cap head screw of M8 × 30 is fixed by positioning seat 3 and main shaft 6, in this way by positioning seat 3, internal tooth die cap 4,6 and of main shaft
The injection molding spatial form that internal spline guide rail 7 is formed substantially forms, and only need to again position internal tooth die cap 4 and positioning seat 3, energy
Determine injection molding space.
As shown in figure 3,3 one side of positioning seat plays a part of determining injection molding space, on the other hand also need to play injection molding
The effect of mouth.Two through-holes are bored on positioning seat 3, are opening two cast gates close to molded portion, can play good pressure maintaining effect in this way
Fruit, the through-hole other end need tapping, facilitate the access of subsequent injection molding copper pipe.
As shown in figure 4, next needing for lower cover 2 and internal spline guide rail 7 to be fixed with screw, it is positioned such that seat 3
It can fall on lower cover 2, so that it is determined that the position of injection molding bottom.Because of the needs of injection molding, lower cover 2 needs to infuse to two
Modeling mouth allows out position, so needing to mill support section two sections, then mills two kidney slots in bottom, facilitates the peace of injection molding copper pipe
Dress and disassembly.
As shown in figure 5, what is finally installed is exactly upper press cover 5, upper press cover 5 is inserted on main shaft 6, then be pressed into internal spline guide rail
In 7, according to technical requirements, the concentricity for needing first to correct main shaft 6 and internal spline guide rail 7 reaches technical requirements, then uses spiral shell
It follows closely and dead.
Injection molding die craft equipment has assembled completion at this time, is next exactly to connect injection molding copper pipe to be molded internal spline guide rail
, notice that above operate must (20 DEG C) progress in thermostatic chamber.
The present invention, which is molded die craft equipment, realizes the injection molding requirement of gear shapping machine internal spline guide rail, improves the resistance to of internal spline guide rail
Mill and shockproof effect, make the precision of gear shapping machine and efficiency be further improved.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
