Embodiment
As shown in Fig. 1 and Fig. 8, embodiment of the present utility model is：The utility model includes cover half module 1 and dynamic
Mould module 2, the utility model is when on injection machine, and the cover half module 1 is fixedly mounted on the left end of the injection machine,
The dynamic model module 2 is fixedly mounted on the right-hand member of the injection machine, for convenience of explanation present embodiment, the utility model
It will be illustrated with installation position as shown in Figure 1.
The cover half module 1 is located at the top of the dynamic model module 2, and the cover half module 1 and the dynamic model module 2 are being closed
The runner 3 with several die cavities being adapted with a whole set of keycap 5 of keyboard with connecting each die cavity is formed after mould, in this tool
In body embodiment, the sum of a set of keycap 5 is 107, so the quantity of the die cavity is also 107；
The dynamic model module 2 includes the first dynamic model block 21, the second dynamic model block 22 and the 3rd dynamic model block 23 set gradually from top to bottom, institute
The middle part for stating the first dynamic model block 21 sets fluted, and the connected cavity plate of four pieces of close splits is installed with the groove
212, the die cavity is located on the upper surface of the cavity plate 212；It is provided with immediately below each die cavity corresponding
Movable core,return core core puller mold insert 4, the top of the movable core,return core core puller mold insert 4 is adapted with the bottom of the keycap 5, and the monnolithic case of movable core,return core core puller mold insert 4 is
Strip, the movable core,return core core puller mold insert 4 is made of softer beryllium copper material, and the bottom of the movable core,return core core puller mold insert 4 is provided with projection 41, institute
The middle part for stating the second dynamic model block 22 is provided with the standing groove 221 being adapted with the bottom of the movable core,return core core puller mold insert 4, the movable core,return core core puller mold insert
4 bottom is fixedly installed in the standing groove 221, and the first dynamic model block 21 is provided with what is passed through for the movable core,return core core puller mold insert 4
Groove 211, the movable core,return core core puller mold insert 4 is connected by the groove 211 with the corresponding die cavity；The movable core,return core core puller mold insert 4 it is upper
Pattern groove 42 is provided with the side at end, the purpose for setting the pattern groove 42 is to reduce the movable core,return core core puller mold insert 4 with described to lead to
Relative friction between groove 211, strengthens the service life of the movable core,return core core puller mold insert 4；The keycap 5 is in injection, the movable core,return core core puller edge
One in top to the position being in contact with the corresponding die cavity on part 4, part of the movable core,return core core puller mold insert 4 to constitute the die cavity
Kind；As shown in figure 5, there is the keycap 5 back-off structure 51 at back-off structure 51 at two, two to be symmetricly set on the keycap
5 both sides, the first dynamic model block 21 is provided with the die cavity being adapted with the back-off structure on the side wall of the groove 211
Groove；The size of the back-off structure 51 is small, when ejecting the keycap 5 in the later stage, it is impossible to ejected using the mode of oblique top or line position
The keycap 5, in this specific embodiment, the mode for ejecting the keycap 5 is, in the first dynamic model block 21 and described second
