Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 5, the present invention provides a movable mold for foil winding coil, which includes an inner mold 10 and an outer mold 20, wherein a gap is formed between the inner mold 10 and the outer mold 20, and a pouring port 21 is disposed on the outer mold 20 for pouring between the inner mold 10 and the outer mold 20.

Specifically, as shown in fig. 1, the inner mold 10 is symmetrically provided with two steel plates, which are formed by rolling steel plates, two ends of each steel plate are bent towards the other inner mold 10, and are arranged in two opposite semicircular shapes, and the inner mold is formed by rolling steel plates, so that the bent parts have better flatness. The two ends of the two inner molds 10 are correspondingly arranged and connected and are connected through the supporting bars 11, and the length of the straight line part of the inner molds 10 can be adjusted by replacing the supporting bars 11, so that the distance between the two bending sides and the outer molds 20 can be adjusted. Sealing gaskets, in this embodiment, silica gel gaskets, are further provided at the joints of the two ends of the inner mold 10, and are used for sealing the joints of the two inner molds 10.

The support bars 11 can play a role in connection and can also play a role in supporting and fixing, in the embodiment, the support plates 12 are arranged on the inner sides of the inner molds 10 in a bending mode, and the inner molds 10 are rolled by steel plates, so that the support plates 12 are arranged to improve the strength and play a role in reinforcement.
