It also comprises internal layer mould clamping device, described internal layer mould clamping device is made up of L plate and bolt II, the long limit of L plate is hinged with pressing plate, the minor face that pressing plate is parallel to L plate is arranged, bolt II is connected with nut through after the minor face of L plate and pressing plate successively, and described leather strap I and leather strap II is arranged between the minor face of pressing plate and L plate.
The bottom of the groove of described outer mould II is provided with eight coil hole.
The long limit that described bolt II is parallel to L plate is arranged.
Described top cover is provided with injecting hole.
The present invention has the following advantages: the two edges of (1) outer mould I of the present invention ride over outer mould II outside, internal layer mould is arranged between outer mould I and outer mould II, the groove of the channel-section steel of outer mould clamping device is buckled on outer mould II, bolt I is pressed on outer mould I, thus outer mould I is fixed on outer mould II by bolt I tightly, when after the complete rubber of coil surface injection moulding, looser a bolt I, make outer mould I and outer mould II separately, only need first looser a bolt II subsequently, rotary pressure plate again, now, clamping force is not had between leather strap I and leather strap II, workman is facilitated to be separated with U-board II by U-board I, finally just can easily finished product coil be taken out, workman is facilitated to take out coil, there is structure simple, assemble firmly feature.(2) top cover of the present invention arranges injecting hole, through after injecting hole, steel cable is fixed on top cover with steel cable, thus facilitates workers carry's coil.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As Figure 1-3, a kind of coil injection molding mould, it comprises internal layer mould, outer mould I1, outer mould II2 and outer mould clamping device, internal layer mould is made up of U-board I3 and U-board II4, the opening of U-board I3 and U-board II4 is oppositely arranged, the edge of U-board I3 and U-board II4 is welded with respectively leather strap I5 and leather strap II6, top cover 7 and bottom 8 is provided with between U-board I3 and U-board II4, the cross section of outer mould I1 takes the shape of the letter U shape, the cross section of outer mould II2 is concave shape, the bottom of the groove of outer mould II2 is provided with coil hole 9, outer mould I1 and outer mould II2 is all arranged between bottom 8 and top cover 7, the outer opening of mould I1 and the groove of outer mould II2 are oppositely arranged, and the two edges of outer mould I1 ride over outer mould II2 outside.As Figure 1-3, internal layer mould is arranged between outer mould I1 and outer mould II2, outer mould clamping device is made up of channel-section steel 10 and bolt I11, the side of channel-section steel 10 is provided with screwed hole, screwed hole is connected with bolt I11, the groove of channel-section steel 10 is buckled on outer mould II2, and bolt I11 is pressed on outer mould I1.
As shown in Figure 4, it also comprises internal layer mould clamping device, described internal layer mould clamping device is made up of L plate 12 and bolt II13, the long limit of L plate 12 is hinged with pressing plate 14, the minor face that pressing plate 14 is parallel to L plate 12 is arranged, bolt II13 is connected with nut 15 through after the minor face of L plate 12 and pressing plate 14 successively, and the long limit that bolt II13 is parallel to L plate 12 is arranged, and leather strap I5 and leather strap II6 is arranged between the minor face of pressing plate 14 and L plate 12.
