Description

TECHNICAL FIELD

[0001] The utility model relates to a mould technical field, concretely is a mould structure. BACKGROUND

[0002] With the development of electric power industry, the demand for dry-type transformer is increasing. The existing dry-type transformer coil manufacturing mold is in an integrated structure, and the mold has large size at one end and small size at the other end, and the whole is a conical mold. When demolding, it can only be pulled out from the large end of the mold, which is laborious and the quality of the coil is not guaranteed. SUMMARY

[0003] In order to solve the problems of the prior art, the utility model provides a mould structure, which comprises: a left half cavity and a right half cavity, the left half cavity and the right half cavity are connected to form a coil manufacturing mold;

[0004] The top and bottom of the coil manufacturing mold are provided with notches;

[0005] The top and bottom of the coil manufacturing mold are provided with locking blocks.

[0006] Further, the top end face size of the coil manufacturing mold is larger than the bottom end face size, and the top and bottom of the coil manufacturing mold are in a round rectangular structure.

[0007] Further, the edges of the top and bottom of the coil manufacturing mold are provided with mold opening handles.

[0008] Further, the locking block is provided with a through hole corresponding to the position of the notch, and the two ends of the locking block are connected with the left half cavity and the right half cavity respectively.

[0009] Further, the top and bottom end faces of the left half cavity and the right half cavity are provided with threaded holes, and the locking block is provided with a through hole corresponding to the position of the threaded hole. The locking block is connected with the left half cavity and the right half cavity through the through hole and the threaded hole.

[0010] The utility model has the advantages of:

[0011] The utility model sets the mold into a pair of plate type assembly structure, which can directly pull open the mold when opening the mold. Compared with the existing direction of pulling open the mold, it is more convenient and will not damage the quality of the coil. The locking block can avoid the problem of misplacement of the mold during use. BRIEF DESCRIPTION OF DRAWINGS

[0016] The technical solutions in the embodiments of the present application will be apparently and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0017] Please refer to Figs. 1-2 The utility model provides a mould structure, include: left half formula cavity 1 and right half formula cavity 2, left half formula cavity 1 with right half formula cavity 2 are opposite and form coil manufacturing mould,

[0018] The top and bottom of the coil manufacturing mould are provided with notches.

[0019] The top and bottom of the coil manufacturing mould are provided with locking blocks 4.

[0020] The top end face size of the coil manufacturing mould is greater than the bottom end face size, and the top and bottom of the coil manufacturing mould are in a rounded rectangular structure.

[0021] The top and bottom of the coil manufacturing mould are provided with open mould handles 3 at the edges.

[0022] The locking block 4 is provided with a through hole 5 corresponding to the position of the notch, and the two ends of the locking block 4 are connected with the left half formula cavity 1 and the right half formula cavity 2 respectively.

[0023] The top and bottom end faces of the left half formula cavity 1 and the right half formula cavity 2 are provided with threaded holes, and the locking block 4 is provided with a through hole 5 corresponding to the position of the threaded hole, and the locking block 4 is connected with the left half formula cavity 1 and the right half formula through a locking member passing through the through hole 5 and the threaded hole.

[0024] The main application point of the application is that the mold structure is arranged as a clamping structure of half type, then the mold is locked by the locking block, the limiting effect of the locking block is contacted in the mold opening, then the mold is directly pulled in two opposite directions, the mold opening is completed, the mold opening process is simple, the coil in the mold is not damaged, and the coil quality is ensured.

[0025] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
