Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these examples are only used for
Bright the utility model rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art
Member falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
A kind of injection moulding apparatus 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.
The Shooting Technique of the utility model 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.
