Detailed Description

The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings and specific embodiments for further understanding the objects, aspects and functions of the present invention, but not for limiting the scope of the appended claims.

With reference to fig. 1 to 3, fig. 1 is a schematic structural diagram of the winding mold of the present invention, and fig. 2 and 3 are schematic structural diagrams of the lower mold and the upper mold of the winding mold of the present invention respectively. The utility model discloses a wire winding mould 10 can be single line wire winding mould or multi-thread wire winding mould, including relative bed die 100 and the last mould 200 that sets up, the core pulling of bed die 100 begins to go into the line when spring shrinkage and mould plane keep unanimous, goes up the cutter of mould 200 and pushes down and cut the unnecessary part of conductor wire in the coil, then bed die 100 loose core can stretch out through the spring and be higher than the mould plane to form the theoretical clearance that sets up with last mould 200 and begin to wind.

In detail, referring to fig. 1 to 5, fig. 4 is an enlarged view of a portion a of fig. 2; fig. 5 is the utility model discloses a structural schematic diagram that the last mould of winding mould's bed die loosed core. Lower mold 100 includes a lower mold core back 110 and a lower clamp 120, with lower mold core back 110 being located in the center of the mold plane of lower mold 100 facing upper mold 200. The lower mold core back 110 includes a lower jaw hole 111 and a thread end placement groove 112, the lower jaw 120 is disposed in the lower jaw hole 111, and the thread end placement groove 112 extends from the lower jaw hole 111 to the edge of the lower mold core back 110.

The upper mold 200 includes an upper mold core 210, an upper collet 220, and a cutter 230, and the upper mold core 210 is located at a center of a mold plane of the upper mold 200 facing the lower mold 100. Wherein the upper chuck 220 is disposed corresponding to the lower chuck 120. The lower chuck hole 111 of the lower mold 100 of the winding mold 10 of the present invention includes an arc-shaped edge 111 a.

With reference to fig. 6, fig. 6 is a front view of the lower mold of the winding mold of the present invention. In the manufacturing process of the product, the end of the conductor wire 20 is located in the wire end placing groove 112 of the lower die 100, and after the wire is fed, the cutting knife 230 (the position of the cutting knife is shown as B in fig. 6) is extended to cut off the excess conductor wire 21. This practical is novel through setting up arc limit 111a, sets up a transition limit that has the radian promptly, and at the excision in-process, unnecessary conductor wire 21 is buckled gradually through arc limit 111a, has avoided the book to lead to the fact the scratch to conductor wire.

In an embodiment of the present invention, the arc-shaped edge 111a has a chamfer radius, and the chamfer radius is 0.5mm to 1.5 mm. Preferably, the chamfer radius of the arc-shaped edge 111a is 1.0 mm.

Wherein the cutting knife 230 of the upper mold 200 is disposed corresponding to the arc-shaped edge 111a of the lower mold 100. The cutting blade 230 is extended to cut out the excess conductor wire 21.

In an embodiment of the present invention, the lower mold core 110 is circular, and the thread end placing groove 112 extends along the radial direction of the lower mold core 110. Lower jaw hole 111 is located in the middle of lower mold core 110. Generally, the upper mold core 210 is circular. The upper die core 210 is opposite to the lower die core 110 and performs winding thereon.

As shown in fig. 5, the lower jaw hole 111 includes a first side 1111 and a second side 1112 opposite to each other, the thread end placement groove 112 extends from the first side 1111 of the lower jaw hole 111 to an edge of the lower mold core 110, and the arc-shaped edge 111a is provided on the second side 1112.
